3 Duty of parents to maintain their children

4 Objects of Act

(1) The principal object of this Act is to ensure that children receive a proper level of financial support from their parents.

(2) Particular objects of this Act include ensuring:

(a) that the level of financial support to be provided by parents for their children is determined according to their capacity to provide financial support and, in particular, that parents with a like capacity to provide financial support for their children should provide like amounts of financial support; and

(b) that the level of financial support to be provided by parents for their children should be determined in accordance with the costs of the children; and

(c) that persons who provide ongoing daily care for children should be able to have the level of financial support to be provided for the children readily determined without the need to resort to court proceedings; and

(d) that children share in changes in the standard of living of both their parents, whether or not they are living with both or either of them; and

(e) that Australia is in a position to give effect to its obligations under international agreements or arrangements relating to maintenance obligations arising from family relationship, parentage or marriage.

(3) It is the intention of the Parliament that this Act should be construed, to the greatest extent consistent with the attainment of its objects:

What is a child support period?

(1) A child support period is a period that:

(a) starts at a time described in subsection (2); and

(b) ends at the time described in subsection (3) that occurs soonest after the start of the period.

Note: Subsections (5) to (8) provide some examples of child support periods. The examples are not exhaustive: see section 15AD of the Acts Interpretation Act 1901.

When does a child support period start?

(2) Each of the following times is the start of a child support period:

(a) the beginning of the day on which an application for an administrative assessment of the child support payable for a child is properly made under Part 4;

(b) the beginning of the day mentioned in paragraph 93(1)(g) (child support payable under a child support agreement accepted by Registrar);

(c) the start of the first day for which a child support agreement described in section 34B is to affect the rate of child support payable for a child;

(d) immediately after the end of the preceding child support period that relates to child support payable for the child (whether it was a period starting as described in paragraph (a), (b) or (c) or this paragraph).

Note: Despite paragraph (2)(a), a child support period might not start if a non‑parent carer applies for an administrative assessment of child support during a child support period (see section 40B).

End of the child support period

(3) The child support period ends at whichever of the following times occurs soonest after the start of the period:

(a) the time 15 months after the period started;

(b) the end of the calendar month during which the Registrar makes an assessment relating to the annual rate of child support payable for the child as required by section 34A (assessment when new tax figure is available);

(d) the end of the day immediately before the first day for which a child support agreement described in section 34B is to affect the rate of child support payable for the child.

Examples

(4) Subsections (5), (6), (7) and (8) merely give a series of examples of the operation of the rules in subsections (1), (2) and (3). The examples involve Mary and Peter. Mary cares for their child and, on 8 June 2000, makes an application under Part 4 and receives a child support assessment for Peter to pay her child support for the child.

Example—initial child support period resulting from application under Part 4

(5) On 20 October 2000, the Registrar makes a new administrative assessment based on an assessment under the income tax law of Peter’s taxable income for the 1999‑2000 year of income (as required by section 34A). The first child support period starts on 8 June 2000 and ends at the end of 31 October 2000, and the second starts on 1 November 2000.

Example—end of child support period if new taxable income not available within 15 months

(6) If no assessment of the taxable income of Mary or Peter for the 1999‑2000 or the 2000‑2001 year of income had been made under the income tax law before the end of 7 September 2001, the first child support period would start on 8 June 2000 and end at the end of 7 September 2001 (15 months after it started).

Example—child support agreement ends existing child support period and starts a new one

(7) If Mary and Peter make a child support agreement to influence the annual rate of child support on and after 15 September 2000:

(a) the child support period that started on 8 June 2000 ends at the end of 14 September 2000; and

(b) a new child support period starts on 15 September 2000.

Example—child support period for child support agreement setting child support rate lasts 15 months

(8) If the child support agreement set the rate of child support payable for the next 2 years (so section 34A did not require the Registrar to make an administrative assessment on 20 October 2000 as described in subsection (5)), the child support period that started on 15 September 2000 would end 15 months later at the end of 14 December 2001 (unless Mary and Peter made another child support agreement to affect the rate of child support payable for a day before 15 December 2001).

7B Meaning of eligible carer

(1) In this Act, eligible carer, in relation to a child, means a person who has at least shared care of the child.

(2) Despite subsection (1), if:

(a) a person cares for a child; and

(b) the person is neither a parent nor a legal guardian of the child; and

(c) a parent or legal guardian of the child has indicated that he or she does not consent to the person caring for the child;

then the person is not an eligible carer in relation to the child unless it would be unreasonable in the circumstances for a parent or legal guardian of the child to care for the child.

(3) For the purposes of subsection (2), it is unreasonable for a parent or legal guardian to care for a child if:

(a) the Registrar is satisfied that there has been extreme family breakdown; or

(b) the Registrar is satisfied that there is a serious risk to the child’s physical or mental wellbeing from violence or sexual abuse in the home of the parent or legal guardian concerned.

9 Interpretation—meaning of separated

For the purposes of this Act, the parents of a child are to be taken to have separated in circumstances in which the parties to a marriage are, under the Family Law Act 1975, taken to have separated.

10 Interpretation—meaning of resident of Australia

For the purposes of this Act, a person is a resident of Australia on a day if on that day the person is a resident of Australia for the purposes of the Income Tax Assessment Act 1936.

12 Interpretation—happening of child support terminating events

(1) A child support terminating event happens in relation to a child if:

(a) the child dies; or

(b) the child ceases to be an eligible child under regulations made under subsection 22(1); or

(ii) otherwise—on the day on which the application is made.

Example: Some reciprocating jurisdictions require that notice be given about the making and substance of the application for administrative assessment of child support and how the person may object to the application, or require that a person have an opportunity to be heard before making a decision on an application.

Note: Part 4A deals with assessments for later child support periods.

(a) a statement that the Registrar was not satisfied under section 29 that the person is a parent of the child; and

Part 4A—Assessments of child support for later child support periods

34A Registrar must make assessment when new tax figure is available

Application of section

(1) This section requires the Registrar to assess the annual rate of child support payable in some cases if:

(a) child support is payable by a liable parent for a child for a day in a child support period (the earlier period); and

(b) during the earlier period, an assessment (the tax assessment) is made under an Income Tax Assessment Act of the taxable income, or any other component of the adjusted taxable income, of the liable parent or the other parent, for the latest year of income (the last year) that ended after the start of the earlier period.

Registrar must make assessment using new tax figures

(2) As soon as practicable after the tax assessment is made, the Registrar must assess the annual rate of child support payable for the child for days in a child support period starting on the first day of the next calendar month (after the calendar month in which the Registrar makes the assessment).

When new assessment is not required

(3) This section does not require the Registrar to make an assessment if:

(a) the Registrar calculates that the tax assessment for the last year could not affect the annual rate of child support payable for the child for a day in a child support period; or

(b) the annual rate of child support payable for the child for the first day of the next calendar month is to be worked out without reference to the actual taxable income of the parent mentioned in paragraph (1)(b) because of:

(i) a child support agreement between the parents of the child; or

(ii) a determination under Part 6A (departure determination); or

(iii) an order made by a court under this Act or the Registration and Collection Act; or

(c) the earlier period will end before the end of the earliest calendar month in which it is practicable for the Registrar to make the assessment mentioned in subsection (2).

Note: In the case of paragraph (3)(c), the Registrar must use the information from the tax assessment to make an assessment for the period starting immediately after the end of the earlier period (unless the information is not relevant to an assessment, because of an agreement, determination or order) (see section 34C).

34B Administrative assessment for child support period started by new agreement when support already payable

(1) The Registrar must assess the annual rate of child support payable for a child for a day in a child support period if:

(a) the Registrar accepts a child support agreement made in relation to the child; and

(b) child support is already payable by a parent for the child under an administrative assessment; and

The Registrar must assess the annual rate immediately after accepting the agreement.

Note 1: Section 95 explains how the provisions of the agreement affect the assessment.

Note 2: If the Registrar makes an assessment under this section, the Registrar must make a provisional notional assessment under section 146B.

(2) The child support period starts:

(a) if:

(i) the application for acceptance of the agreement was made to the Registrar within 28 days after the day on which the agreement was signed; and

(ii) the agreement states that child support is to be payable from a specified day; and

(iii) the day specified is not earlier than the day on which child support first became payable under the administrative assessment;

on the specified day; or

(b) if:

(i) the application for acceptance of the agreement was made to the Registrar within 28 days after the day on which the agreement was signed; and

(ii) the agreement states that child support is to be payable from a specified day; and

(iii) the day specified is earlier than the day on which child support first became payable under the administrative assessment;

on the day on which child support first became payable under the administrative assessment; or

(i) the application for acceptance of the agreement was made to the Registrar within 28 days after the day on which the agreement was signed; and

(ii) the agreement does not specify a day from which child support is to be payable;

on the day on which the agreement was signed; or

(d) otherwise—on the day on which the application was made to the Registrar for acceptance of the agreement.

(3) However, if the applicant for acceptance of the agreement is a resident of a reciprocating jurisdiction, subsection (2) applies as if the references in subparagraphs (2)(a)(i), (b)(i) and (c)(i) were references to 90 days instead of 28 days.

34C Administrative assessments for child support periods not started by application or new agreement

The Registrar must assess under this Act the annual rate of child support payable for a child for days in a child support period either before, or as soon as practicable after, the start of the period unless:

(a) the period starts when the application is made under Part 4; or

(b) the period starts on a day mentioned in paragraph 93(1)(g); or

(c) an assessment of the child support payable for the child for days in the period has already been made as required by section 34A; or

(d) the period starts on the first day for which a child support agreement described in subsection 34B(1) is to affect the annual rate of child support payable for the child.

Note 1: Section 31 requires the Registrar to make an assessment of child support payable as quickly as possible after accepting an application under Part 4.

Note 2: Subsection 93(2) requires the Registrar to make an assessment of child support payable as soon as practicable after accepting certain child support agreements.

Note 3: If a child support agreement has effect for the purposes of the child support period, it will affect the assessment (see section 95).

Part 5—Administrative assessment of child support

Division 1—Preliminary

35A Simplified outline

The following is a simplified outline of this Part:

• This Part includes the formulas used for assessing the annual rate of child support payable by a parent for a child for a day in a child support period (other than in cases where that rate is worked out in accordance with a child support agreement, a Registrar’s determination under Part 6A or a court order).

• The Costs of the Children Table published by the Secretary each year (based on the table in Schedule 1 to this Act) sets out the costs to parents of raising children in various age ranges.

• Those costs are to be met by both parents (by paying child support or by caring for their children) according to each parent’s capacity to meet the costs.

• To determine each parent’s capacity to meet those costs, the parents are assessed in respect of the costs of the child.

• Generally, both parents’ income is taken into account in determining each parent’s capacity to meet the costs of their children.

• The formulas also allow child support payable to non‑parent carers of children to be worked out.

Division 2—The formulas

Subdivision A—Preliminary

35B Simplified outline

The following is a simplified outline of this Division:

• The Costs of the Children Table published by the Secretary each year (based on the table in Schedule 1 to this Act) sets out the costs to parents of raising children in various age ranges.

• These costs are to be met by both parents (by paying child support or by caring for their children) according to each parent’s capacity to meet the costs.

• To determine each parent’s capacity to meet the costs, the parents are assessed in respect of the costs of the child.

• Formulas 1 and 2 apply if both parents’ incomes are taken into account in determining each parent’s capacity to meet the costs of their children, and each parent only has one child support case.

• Formulas 3 and 4 apply if both parents’ incomes are taken into account in determining each parent’s capacity to meet the costs of their children, and at least one of the parents has multiple child support cases.

• Formulas 5 and 6 apply if only one parent’s income is taken into account in determining the parent’s capacity to meet the costs of his or her children (such as because the other parent is not a resident of Australia).

• Formulas 2, 4, 5 and 6 also allow child support payable to non‑parent carers of children to be worked out.

• In some cases, the annual rate of child support payable by a parent is assessed under Subdivision B of Division 8 (low income parents and minimum annual rates of child support).

35C Application of Part to determine annual rate of child support

This Part applies in relation to the assessment of child support payable by a parent for a child, subject to:

(a) any determination made by the Registrar under Part 6A (departure determinations); and

(b) any order made by a court under Division 4 of Part 7 (departure orders); and

(c) any provisions of a child support agreement that have effect, for the purposes of this Part and section 142, as if they were such an order made by consent.

Subdivision B—Working out annual rates of child support using incomes of both parents in single child support case

35D Application of Subdivision

(1) The annual rate of child support payable for a child for a day in a child support period is assessed under this Subdivision if:

(a) both parents of the child are to be assessed in respect of the costs of the child; and

(b) both parents are to be assessed only in respect of the costs of:

(i) that child; and

(ii) any other child in the child support case that relates to that child.

(2) Subsection (1) does not apply if at least one of the parents is liable to pay child support for a child under an administrative assessment under the law of a reciprocating jurisdiction.

35 Formula 1: Method statement using incomes of both parents in single child support case with no non‑parent carer

This is how to work out the annual rate of child support payable for a child for a day in a child support period if no non‑parent carer has a percentage of care for the child for the day.

Method statement

Step 1. Work out each parent’s child support income for the child for the day (see section 41).

Step 2. Work out the parents’ combined child support income for the child for the day (see section 42).

Step 3. Work out each parent’s income percentage for the child for the day (see section 55B).

Step 4. Work out each parent’s percentage of care for the child for the day (see Subdivision B of Division 4 of Part 5).

Step 5. Work out each parent’s cost percentage for the child for the day (see section 55C).

Step 6. Work out each parent’s child support percentage for the child for the day (see section 55D).

Step 7. Work out the costs of the child for the day under sections 55G and 55H.

Step 8. If a parent has a positive child support percentage under step 6, the annual rate of child support payable by the parent for the child for the day is worked out using the formula:

Start formula Parent's child support percentage for the child for the day times Costs of the child for the day end formula

Note: If a parent’s percentage of care for a child is more than 65%, the parent’s annual rate of child support for the child is nil (see section 40C).

36 Formula 2: Working out annual rates of child support using incomes of both parents in single child support case with a non‑parent carer

(1) This is how to work out the annual rate of child support payable for a child for a day in a child support period if one or more non‑parent carers have a percentage of care for the child for the day.

(2) Follow steps 1 to 8 of the method statement in section 35 for each parent (disregarding subsection 55D(2) (negative child support percentages)).

Annual rate payable by parent

(3) If a parent’s (the first parent’s) child support percentage under step 6 of the method statement in section 35 is positive, then the annual rate of child support payable by the first parent for the child for the day is the annual rate of child support for the child worked out under step 8 of the method statement.

Annual rate payable only to non‑parent carers

(4) If:

(a) the second parent’s child support percentage is also positive; or

(b) the second parent’s child support percentage is nil or negative, and the second parent does not have at least shared care of the child during the relevant care period;

then, subject to section 40B, the first parent must pay the annual rate of child support that is payable by the first parent for the child under subsection (3) to the non‑parent carer or carers in accordance with section 40A.

Note 1: If both parents have a positive child support percentage, then the non‑parent carer or carers are entitled to be paid the total of the 2 annual rates of child support that are payable by the parents for the child.

Note 2: Under section 40B, a non‑parent carer of a child is not entitled to be paid child support unless he or she applies under section 25A in relation to the child.

Annual rate payable to parent and non‑parent carer

(5) If the second parent’s child support percentage is negative, and the second parent has at least shared care of the child during the relevant care period, then:

(a) the first parent must pay to the second parent the annual rate of child support for the child worked out under step 8 of the method statement using the second parent’s negative child support percentage (expressed as a positive); and

(b) subject to section 40B, the first parent must pay to the non‑parent carer an annual rate of child support for the child that is the difference between:

(i) the annual rate of child support payable by the first parent for the child under subsection (3); and

(ii) the rate referred to in paragraph (a) of this subsection.

Subdivision C—Working out annual rates of child support using incomes of both parents in multiple child support cases

36A Application of Subdivision

(1) The annual rate of child support payable for a child for a day in a child support period is assessed under this Subdivision if:

(a) both parents of the child are to be assessed in respect of the costs of that child; and

(b) at least one of the parents of the child is to be assessed in respect of the costs of another child in another child support case.

(2) For the purposes of paragraph (1)(b), a parent is taken to be assessed in respect of the costs of another child in another child support case if the parent is liable to pay child support for that child under an administrative assessment under the law of a reciprocating jurisdiction.

37 Formula 3: Method statement using incomes of both parents in multiple child support cases with no non‑parent carer

This is how to work out the annual rate of child support payable for a child for a day in a child support period if no non‑parent carer has a percentage of care for the child for the day.

Method statement

Step 1. Follow steps 1 to 6 in the method statement in section 35 for each parent.

Step 1A. Work out the costs of the child for the day under section 55HA.

Step 1B. If a parent has a positive child support percentage under step 6 of the method statement in section 35, work out the following rate:

Start formula Parent's child support percentage for the child for the day times Costs of the child for the day end formula

Step 2. Work out each parent’s multi‑case cap (if any) for the child for the day (see section 55E).

Step 3. If a parent has a positive child support percentage under step 6 of the method statement in section 35, the annual rate of child support payable by the parent for the child for the day is the lower of:

(a) the rate worked out under step 1B of the method statement in this section; and

(b) the parent’s multi‑case cap (if any) for the child for the day.

Note: If a parent’s percentage of care for a child is more than 65%, the parent’s annual rate of child support for the child is nil (see section 40C).

38 Formula 4: Working out annual rates of child support using incomes of both parents in multiple child support cases with a non‑parent carer

(2) Follow steps 1 to 6 of the method statement in section 35 for each parent (disregarding subsection 55D(2) (negative child support percentages)).

(2A) Work out the costs of the child for the day under section 55HA.

(2B) If a parent has a positive child support percentage under step 6 of the method statement in section 35, work out the following rate:

Start formula Parent's child support percentage for the child for the day times Costs of the child for the day end formula

(3) Work out each parent’s multi‑case cap (if any) for the child for the day (see section 55E).

Annual rate payable by parent

(4) If a parent’s (the first parent’s) child support percentage under step 6 of the method statement in section 35 is positive, then the annual rate of child support payable by the first parent for the child for the day is the lower of:

(a) the rate worked out under subsection (2B); and

(b) the first parent’s multi‑case cap (if any) for the child for the day.

Annual rate payable only to non‑parent carers

(5) If:

(a) the second parent’s child support percentage is also positive; or

(b) the second parent’s child support percentage is nil or negative, and the second parent does not have at least shared care of the child during the relevant care period;

then, subject to section 40B, the first parent must pay the annual rate of child support that is payable by the first parent for the child under subsection (4) to the non‑parent carer or carers in accordance with section 40A.

Note 2: Under section 40B, a non‑parent carer of a child is not entitled to be paid child support unless he or she applies under section 25A in relation to the child.

Annual rate payable to parent and non‑parent carer

(6) If:

(a) the second parent’s child support percentage is negative; and

(b) the second parent has at least shared care of the child during the relevant care period;

then, subject to section 40B, the first parent must pay the annual rate of child support that is payable by the first parent for the child under subsection (4) to the second parent and the non‑parent carer in accordance with section 40A.

Subdivision D—Working out annual rates of child support using income of one parent

38A Application of Subdivision

The annual rate of child support payable for a child for a day in a child support period is assessed under this Subdivision if only one parent of the child is to be assessed in respect of the costs of the child.

39 Formula 5: Method statement using income of one parent where other parent not a resident of Australia or in special circumstances

(1) This is how to work out the annual rate of child support payable for a child for a day in a child support period if a non‑parent carer of the child has applied for a parent of the child to be assessed in respect of the costs of the child because of subparagraph 25A(b)(ii) or (iii) (non‑resident of Australia or special circumstances).

Method statement

Step 1. Work out the parent’s child support income for the day (see section 41) and double that income.

Step 2. Work out the parent’s percentage of care for the child for the day (see Subdivision B of Division 4 of Part 5).

Step 3. Work out the parent’s cost percentage for the child for the day (see section 55C).

Step 4. If the parent is assessed in respect of the costs of another child who is in another child support case, work out the costs of the child for the day under section 55HA. Otherwise, work out the costs of the child for the day under sections 55G and 55H. Assume, in applying section 55G or 55HA and Schedule 1, that the reference to the child support income of the parent in the Costs of the Children Table is a reference to the amount worked out under step 1.

Step 5. Work out the following rate:

$Start formula start fraction 1 over 2 end fraction times open square bracket Costs of the child for the day minus open bracket Parent's cost percentage for the child for the day times Costs of the child for the day close bracket close square bracket end formula$

Step 6. If the parent is not assessed in respect of the costs of another child who is in another child support case, the annual rate of child support payable by the parent for the child for the day is the rate worked out under step 5.

Step 7. If the parent is assessed in respect of the costs of another child who is in another child support case, work out the parent’s multi‑case cap for the child for the day (see section 55E).

Step 8. The annual rate of child support payable by the parent for the child for the day is the lower of:

(a) the rate worked out under step 5; and

(b) the parent’s multi‑case cap for the child for the day.

Step 9. If there is only one non‑parent carer who has a percentage of care for the child for the day, the parent must pay the annual rate of child support that is payable for the child under step 5 or 8 to the non‑parent carer. If there are 2 non‑parent carers who have a percentage of care for the child for the day, then, subject to section 40B, the parent must pay the annual rate of child support that is payable for the child under step 5 or 8 to the non‑parent carers in accordance with section 40A.

Note: Under section 40B, a non‑parent carer of a child is not entitled to be paid child support unless he or she applies under section 25A in relation to the child.

(2) For the purposes of steps 4, 6 and 7 of the method statement in subsection (1), a parent is taken to be assessed in respect of the costs of another child who is in another child support case if the parent is liable to pay child support for that child under an administrative assessment under the law of a reciprocating jurisdiction.

40 Formula 6: Method statement using income of one parent where other parent deceased

Method statement

Step 1. Work out the parent’s child support income for the day (see section 41).

Step 2. Work out the parent’s percentage of care for the child for the day (see Subdivision B of Division 4 of Part 5).

Step 3. Work out the parent’s cost percentage for the child for the day (see section 55C).

Step 5. Work out the following rate:

Start formula Costs of the child for the day minus open bracket Parent's cost percentage for the child for the day times Costs of the child for the day close bracket end formula

Step 7. If the parent is assessed in respect of the costs of another child who is in another child support case, work out the parent’s multi‑case cap for the child for the day (see section 55E).

Step 8. The annual rate of child support payable by the parent for the child for the day is the lower of:

(a) the rate worked out under step 5; and

(b) the parent’s multi‑case cap for the child for the day.

Note: Under section 40B, a non‑parent carer of a child is not entitled to be paid child support unless he or she applies under section 25A in relation to the child.

Subdivision E—General provisions

40A Cases where there is more than one person entitled to child support

(1) If, in applying:

(a) subsection 36(4) or 38(5) or (6); or

(b) step 9 in the method statement in subsection 39(1) or 40(1); or

child support is payable to:

(d) a parent and a non‑parent carer of a child; or

(e) 2 non‑parent carers of a child;

then, the annual rate of child support for the child for a day in the child support period that each parent or non‑parent carer (as the case requires) is, subject to section 40B, entitled to be paid is:

$Start formula Total rate to which parent and non-parent carers are entitled to be paid for the day times start fraction Parent's or non-parent carer's cost percentage for the child for the day over Total parent's and non-parent carer's cost percentages for the child for the day end fraction end formula$

Note: Under section 40B, a non‑parent carer of a child is not entitled to be paid child support unless he or she applies under section 25A in relation to the child.

(2) In applying subsection (1), even if a non‑parent carer is not entitled to be paid an annual rate of child support because of section 40B, the non‑parent carer’s cost percentage is taken into account.

40B Non‑parent carer must have applied for child support

(1) A non‑parent carer of a child is not, under section 36, 38, 39, 40, 65A or 66, entitled to be paid an annual rate of child support for the child for a day in a child support period unless the non‑parent carer has made an application under section 25A in relation to the child.

(2) If a non‑parent carer is not entitled to be paid child support for a child for a day in a child support period under subsection (1), the annual rate of child support payable by the parent for the child for the day is reduced by the amount that is not payable because of subsection (1).

(3) If:

(a) a non‑parent carer of a child has not so applied at the time the administrative assessment of child support for the child for the child support period is made; but

(b) the non‑parent carer does so during the child support period;

then:

(c) the non‑parent carer is entitled to be paid an annual rate of child support for the child worked out under this Part from the day on which the non‑parent carer makes the application under section 25A; and

(d) despite paragraph 7A(2)(a), a new child support period is not started by that application.

40C Parents with more than 65% care

The annual rate of child support payable by a parent for a child for a day in a child support period is nil if:

(a) the parent’s annual rate of child support for the child is worked out under section 35 or 37 (income of both parents, no non‑parent carer); and

(b) the parent’s percentage of care determined for the purposes of the administrative assessment of child support for the child is more than 65%.

40D Parents with nil child support percentage

The annual rate of child support payable by a parent for a child for a day in a child support period is nil if the parent’s child support percentage for the child for the day is nil.

Division 3—Child support income

Subdivision A—Preliminary

40E Simplified outline

The following is a simplified outline of this Division:

• The income used in determining a parent’s capacity to meet the costs of his or her children might be reduced by the following amounts:

(a) the self‑support amount (to take account of the parent’s need to support himself or herself);

(b) a relevant dependent child amount (if the parent cares for a relevant dependent child or step‑child of the parent);

• The relevant dependent child amount and the multi‑case allowance take account of the costs of relevant dependent children, and children in other child support cases, in a similar way to the way in which the costs of the children are worked out for children in a child support case.

• A parent’s adjusted taxable income for a year of income can be reduced under section 44 in respect of a particular child if the parent earns additional income during the first 3 years after separating from the other parent of the child.

Subdivision B—Child support income and combined child support income

41 Working out parent’s child support income

Single child support case—no relevant dependent children

(1) If:

(a) a parent is to be assessed in respect of the costs of a child in only one child support case; and

(b) the parent does not have a relevant dependent child;

the parent’s child support income for the child for a day in a child support period is the amount worked out using the formula:

Start formula Parent's adjusted taxable income for the child for the day minus Parents self-supported amount for the day end formula

Single child support case—relevant dependent children

(2) If:

(a) a parent is to be assessed in respect of the costs of a child (the particular child) in only one child support case; and

(b) the parent has at least one relevant dependent child;

the parent’s child support income for the particular child for a day in a child support period is the amount worked out using the formula:

Start formula Parent's adjusted taxable income for the particular child for the day minus Parent's self-supported amount for the day minus Parent's relevant dependent child amount for the day end formula

Multiple child support cases—no relevant dependent children

(3) If:

(a) a parent is to be assessed in respect of the costs of a child (the particular child); and

(b) the parent is also to be assessed in respect of the costs of another child in another child support case; and

the parent’s child support income for the particular child for a day in a child support period is the amount worked out using the formula:

Start formula Parent's adjusted taxable income for the particular child for the day minus Parent's self-support amount for the day minus Parent's multi-case allowance for the particular child for the day end formula

Multiple child support cases—relevant dependent children

(4) If:

(a) a parent is to be assessed in respect of the costs of a child (the particular child); and

(b) the parent is also to be assessed in respect of the costs of another child in another child support case; and

the parent’s child support income for the particular child for a day in a child support period is the amount worked out using the formula:

Start formula Parent's adjusted taxable income for the particular child for the day minus Parent's self-support amount for the day minus Parent's relevant dependent child amount for the day minus Parent's multi-case allowance for the particular child for the day end formula

Negative result taken to be nil

(5) A parent’s child support income for a day in a child support period is taken to be nil if the amount worked out using a formula in this section is negative.

Administrative assessments under laws of reciprocating jurisdictions

(6) Subsection (1) or (2) does not apply if the parent is liable to pay child support for a child under an administrative assessment under the law of a reciprocating jurisdiction.

(7) For the purposes of paragraphs (3)(b) and (4)(b), a parent is taken to be assessed in respect of the costs of another child in another child support case if the parent is liable to pay child support for that child under an administrative assessment under the law of a reciprocating jurisdiction.

42 Working out parents’ combined child support income

Work out the parents’ combined child support income for a child for a day in a child support period by adding together each parent’s child support income for the child for the day.

Subdivision C—Working out the components of child support income

43 Working out parent’s adjusted taxable income

(1) Subject to this Part, a parent’s adjusted taxable income for a child for a day in a child support period is the total of the following components:

(a) the parent’s taxable income for the last relevant year of income in relation to the child support period, disregarding the parent’s assessable FHSS released amount (within the meaning of the Income Tax Assessment Act 1997) for that year of income;

(b) the parent’s reportable fringe benefits total for that year of income;

(d) the parent’s total net investment loss (within the meaning of the Income Tax Assessment Act 1997) for that year of income;

(e) the total of the tax free pensions or benefits received by that parent in that year of income;

(f) the parent’s reportable superannuation contributions (within the meaning of the Income Tax Assessment Act 1997) for that year of income.

Note 1: Other provisions that relate to a person’s adjusted taxable income are section 34A and Subdivisions B and C of Division 7.

Note 2: The components of the definition of adjusted taxable income are defined in section 5.

(2) If the Registrar amends an assessment under section 44, then for the purposes of the assessment, the person’s adjusted taxable income for a child to whom the assessment relates, for a day in the child support period, is the amount determined by the Registrar.

44 Post‑separation costs

Application for post‑separation income to be excluded

(1) A parent (the applicant) of a child may apply to the Registrar to amend an administrative assessment of child support payable by or to the parent for the child for part of a child support period if:

(a) the applicant and the other parent of the child lived together on a genuine domestic basis for at least 6 months; and

(b) the separation, following that 6 month period, of the applicant from the other parent occurred:

(i) within the last 3 years; and

(ii) before the application for administrative assessment of child support for the child was made under section 25 or 25A; and

(d) in the last relevant year of income, or in the application period for an income election (if such an election has been made by the parent), the applicant earns, derives or receives income:

(i) in accordance with a pattern of earnings, derivation or receipt that is established after the applicant and the other parent first separate; and

(ii) that is of a kind that it is reasonable to expect would not have been earned, derived or received in the ordinary course of events.

(2) If the applicant makes an application under this section, the Registrar may determine that the applicant’s adjusted taxable income for the child for a day in the child support period is a specified amount that excludes the income referred to in paragraph (1)(d).

(3) However, the Registrar may make a determination under subsection (2) only if the determination:

(a) reduces the applicant’s adjusted taxable income for the child for a day in the child support period by 30% or less; and

(b) applies in respect of a day in the child support period, being a day that is less than 3 years after the last separation referred to in paragraph (1)(b).

Registrar to implement determinations

(4) The Registrar is to take such action as is necessary to give effect to the determination by amending any administrative assessment that has been made in relation to the child support period.

Notice to be served if Registrar refuses application

(5) If the Registrar refuses to make a determination under subsection (2), the Registrar must serve written notice of the decision on the applicant.

(6) The notice must include, or be accompanied by, a statement to the effect:

(a) that the applicant may, subject to the Registration and Collection Act, object to the particulars of the assessment in relation to which the applicant sought to make the application; and

(b) that if the applicant is aggrieved by the decision on the objection, he or she may, subject to that Act and the AAT Act, apply to the AAT for review of the decision.

(7) This section does not prevent the Registrar from making a new assessment for part of the child support period.

Note: This section does not limit the power under section 75 to amend assessments (see subsection 75(5)).

45 Working out the self‑support amount

A parent’s self‑support amount for a day in a child support period is:

$Start formula start fraction 1 over 3 end fraction times Annualised MTAWE figure for the relevant June quarter end formula$

Note: A parent’s self‑support amount can be varied by a determination or order under section 98S or 118.

46 Working out parent’s relevant dependent child amount

A parent’s relevant dependent child amount for a day in a child support period is the total of the amounts worked out for each relevant dependent child of the parent using this method statement.

Method statement

Step 1. Work out the difference between the parent’s adjusted taxable income for the child for the day and the parent’s self‑support amount for the day (see sections 43 and 45).

Step 2. Work out the parent’s percentage of care for the child for the day (see Subdivision B of Division 4 of Part 5).

Step 3. Work out the parent’s cost percentage for the child for the day (see section 55C).

Step 4. Work out the costs of the child for the day under sections 55G and 55H as if:

(a) the parent’s annual rate of child support were assessed under Subdivision D of Division 2; and

(b) the reference in subsection 55G(2) to the parent’s child support income were a reference to the amount worked out under step 1; and

(c) references in sections 55G and 55H to children in the child support case that relates to the child were references to all of the parent’s relevant dependent children.

Step 5. Work out the following amount for the child for a day in the child support period:

Start formula Parent's cost percentage for the child under step 3 times Costs of the child under step 4 end formula

Note: Section 73A deals with the Registrar discovering, after making an administrative assessment, that a parent has a relevant dependent child.

47 Working out multi‑case allowances

(1) A parent’s multi‑case allowance for a child (the particular child) for a day in a child support period is worked out using this method statement.

Method statement

Step 1. Work out the following amount:

Start formula Parent's adjusted taxable income for the particular child for the day minus self-support amount for the day end formula

Step 2. If the parent has a relevant dependent child, take the parent’s relevant dependent child amount (see section 46) for the day from the amount worked out under step 1.

Step 3. For each of the children (the multi‑case children) for whom the parent is assessed in respect of the costs of the child for the day, work out the multi‑case child costs for the particular child for the day under section 55HA, as if:

(a) the parent’s annual rate of child support were assessed under Subdivision D of Division 2; and

(b) the reference in subsection 55HA(2) to the parent’s child support income were a reference to the amount worked out under step 1 or 2 (as the case requires); and

(c) references in section 55HA to children in the child support case that relates to the child were references to all of the parent’s multi‑case children.

Step 4. The parent’s multi‑case allowance for the particular child for the day is the sum of the multi‑case child costs for each of the other multi‑case children (excluding the particular child and any other children in the child support case that relates to the particular child).

(2) For the purposes of step 3 of the method statement, a parent is taken to be assessed in respect of the costs of a child if the parent is liable to pay child support for the child under an administrative assessment under the law of a reciprocating jurisdiction.

Division 4—Percentage of care

Subdivision A—Preliminary

48 Simplified outline

The following is a simplified outline of this Division:

• A responsible person’s percentage of care for a child during a care period is the percentage of care determined by the Registrar under Subdivision B of this Division.

Division 5—Working out other elements for the formulas

Subdivision A—Preliminary

55A Simplified outline

The following is a simplified outline of this Division:

• A parent’s income percentage represents the parent’s capacity to meet the costs of the child.

• A parent’s cost percentage represents the extent to which the parent is taken to have met the costs of the child through care.

• A parent’s child support percentage is the difference between the parent’s income percentage and his or her cost percentage. Generally, if the parent has a positive child support percentage, the annual rate of child support payable by the parent is that percentage of the costs of the child.

• If a parent has multiple child support cases, the annual rate of child support payable by the parent for a child is capped by the parent’s multi‑case cap for the child.

Subdivision B—Working out other elements for the formulas

55B Working out income percentages

Work out each parent’s income percentage for a child for a day in a child support period using the formula (worked out to 2 decimal places, rounding up if the third decimal place is 5 or more):

$Start formula start fraction Parent's child support income for the child for the day over Parents' combined child support income for the child for the day end fraction end formula$

55C Working out cost percentages

A parent’s or non‑parent carer’s cost percentage for a child for a day in a child support period is the percentage worked out using the table based on the parent’s or non‑parent carer’s (as the case requires) percentage of care for the child for the day.

Cost percentages
Item	Column 1 Percentage of care	Column 2 Cost percentage
1	0 to less than 14%	Nil
2	14% to less than 35%	24%
3	35% to less than 48%	25% plus 2% for each percentage point over 35%
4	48% to 52%	50%
5	more than 52% to 65%	51% plus 2% for each percentage point over 53%
6	more than 65% to 86%	76%
7	more than 86% to 100%	100%

55D Working out child support percentages

(1) Work out each parent’s child support percentage for a child for a day in the child support period using the formula:

(2) A parent’s child support percentage for a day in a child support period is taken to be nil if the amount worked out using the formula is negative.

55E Working out the multi‑case cap

(1) Work out a parent’s multi‑case cap for a child (the particular child) for a day in a child support period in accordance with subsection (2) if:

(a) the parent’s annual rate of child support for the particular child is assessed for the day under section 37, 38, 39 or 40; and

(b) if section 37 or 38 applies—the parent has a positive child support percentage for the particular child under step 6 of the method statement in section 35; and

(c) in any case—the parent is assessed for the day in respect of the costs of another child who is in another child support case.

(2) The parent’s multi‑case cap for the particular child for the day is worked out using the formula:

Start formula open bracket 100% minus Parent's cost percentage for the particular child for the day close bracket times Multi-case child costs for the particular child for the day end formula

(3) For the purposes of paragraph (1)(c), a parent is taken to be assessed for a day in respect of the costs of another child who is in another child support case if the parent is liable to pay child support for that child for the day under an administrative assessment under the law of a reciprocating jurisdiction.

Division 6—The costs of the child

Subdivision A—Preliminary

55F Simplified outline

The following is a simplified outline of this Division:

• The costs of the children are worked out using the rules in this Division and the Costs of the Children Table in Schedule 1.

• The costs of the children are based on the number of children in a child support case and the ages of those children.

• The costs of the child are the costs of the children divided by the number of children in the child support case.

• The Costs of the Children Table is updated every year to reflect changes to the annualised MTAWE figure.

Subdivision B—The costs of the child

55G Working out the costs of the children

(1) If an annual rate of child support for a day in a child support period is assessed for a child under section 35 or 36 (Formulas 1 and 2), identify the column in the Costs of the Children Table for that child support period that covers the combined child support income of the parents of the child.

Note: The Secretary publishes the updated Costs of the Children Table in the Gazette each year for child support periods that begin in the next year (see section 155).

(2) If:

(a) an annual rate of child support for a day in a child support period is assessed for a child under Subdivision D of Division 2 (Formulas 5 and 6); and

(b) the parent of the child is not assessed in respect of the costs of another child who is in another child support case;

identify the column in the Costs of the Children Table for that child support period that covers the child support income of the parent of the child.

Note: This subsection also applies in working out the relevant dependent child amount (see step 4 of the method statement in section 46).

(3) Identify the number of children (the child support children) in the child support case that relates to the child.

(4) Identify the ages of the child support children on the day. If there are more than 3 child support children, use the ages of the 3 oldest children.

(5) Identify the item in the relevant column in the Costs of the Children Table that covers that number of child support children of those ages.

(6) The amount worked out for the item in accordance with Schedule 1 to this Act is the costs of the children.

(7) For the purposes of paragraph (2)(b), a parent is taken to be assessed in respect of the costs of another child who is in another child support case if the parent is liable to pay child support for that child under an administrative assessment under the law of a reciprocating jurisdiction.

55H Working out the costs of the child

For the purposes of section 55G, the costs of a child for a day in a child support period is:

(a) if there is only one child support child—the costs of the children; and

(b) otherwise—the costs of the children divided by the number of child support children.

55HA Working out the costs of the child if parents have multiple child support cases

(1) If an annual rate of child support for a day in a child support period is assessed for a child under section 37 or 38 (Formulas 3 and 4), identify the column in the Costs of the Children Table for that child support period that covers the combined child support income of the parents of the child.

Note: The Secretary publishes the updated Costs of the Children Table in the Gazette each year for child support periods that begin in the next year (see section 155).

(2) If:

(a) an annual rate of child support for a day in a child support period is assessed for a child under Subdivision D of Division 2 (Formulas 5 and 6); and

(b) the parent of the child is assessed in respect of the costs of another child who is in another child support case;

identify the column in the Costs of the Children Table for that child support period that covers the child support income of the parent of the child.

Note: This subsection also applies in working out the multi‑case allowance (step 3 of the method statement in section 47).

(3) Identify the number of children (the child support children) in the child support case that relates to the child.

(4) Identify the ages of the child support children on the day.

(5) In respect of each of the child support children:

(a) assume that all of the child support children are the same age as that child; and

(b) identify the item in the relevant column in the Costs of the Children Table that covers that number of child support children of that age.

(If there are more than 3 child support children, use the row for 3 children.)

(6) For the purposes of this section, the costs of the child for a day in a child support period, in respect of each child, is the amount worked out, in accordance with Schedule 1 to this Act, for the item identified for that child divided by the number of child support children.

Division 7—Assessments and estimates of adjusted taxable income

Subdivision A—Preliminary

55J Simplified outline

The following is a simplified outline of this Division:

• A parent’s taxable income is generally the amount of taxable income that is assessed under an Income Tax Assessment Act.

• The Registrar may determine a parent’s adjusted taxable income in certain circumstances.

• There are limits on the Registrar’s ability to amend an assessment for past periods if the parent later lodges his or her tax return.

• A parent can estimate the amount of his or her adjusted taxable income for a year of income.

Subdivision B—Adjusted taxable income determined by reference to taxable income etc.

56 Taxable income is as assessed under Income Tax Assessment Act

Meaning of taxable income

(1) For the purposes of assessing a parent in respect of the costs of a child in relation to a child support period, if the parent’s taxable income has been assessed under an Income Tax Assessment Act for the last relevant year of income in relation to the child support period, the parent’s taxable income for that year is the amount as so assessed.

Note: Sections 34A and 57 are also relevant to a person’s taxable income.

When amended tax assessment may be taken into account

(2) If, after an administrative assessment of child support is made, the assessment (the tax assessment) of a parent’s taxable income is amended (whether or not because of an objection, appeal or review), the Registrar may amend the administrative assessment to take account of the amendment to the tax assessment.

Retrospective determinations

(2A) An amendment of the administrative assessment under subsection (2) must be on the basis that the parent’s adjusted taxable income for that year of income is, and has always been, the amount worked out as a result of the amended tax assessment if:

(a) the parent’s adjusted taxable income worked out as a result of the amended tax assessment is higher than the parent’s previous adjusted taxable income; or

(b) the parent applied for the amendment of the tax assessment on or before:

(i) the day by which the parent was required to lodge his or her income tax return for that year of income with the Commissioner of Taxation (taking into account any deferral under section 388‑55 in Schedule 1 to the Taxation Administration Act 1953); or

(ii) the end of 28 days after the parent was given the tax assessment (including an amended tax assessment) by the Commissioner of Taxation; or

(iii) the end of 28 days after the parent becomes aware that the tax assessment is not correct if the parent did not apply for the amendment on or before a day referred to in subparagraph (i) or (ii) because of circumstances beyond the knowledge or control of the parent; or

(c) the parent did not apply for the amendment of the tax assessment on or before any of the days referred to in paragraph (b), but the Registrar is satisfied that special circumstances exist.

Prospective determinations

(2B) If subsection (2A) does not apply, an amendment of the administrative assessment under subsection (2) for a child support period must be on the basis that for each later day in the period the parent’s adjusted taxable income for that year of income is the amount worked out as a result of the amended tax assessment.

Date of assessment of a parent’s taxable income taken to be date of notice of the assessment

(3) For the purposes of this section, if:

(a) notice of an assessment (including an amended assessment) of a parent’s taxable income under an Income Tax Assessment Act has been served on the parent under the Income Tax Assessment Act 1936; and

(b) the notice is dated;

then the assessment is taken to have been made on the date of the notice.

Section not to affect determinations, court orders or consent orders

(4) This section does not prevent:

(a) the Registrar from making any determination under Part 6A (departure determinations); or

(b) a court from making any order under Division 4 of Part 7 (departure orders); or

(c) the making, and acceptance by the Registrar, of a child support agreement that includes provisions that have effect for the purposes of this Part as if they were such an order made by consent.

57 Taxable income for child support purposes where taxable income determined to be nil under Income Tax Assessment Act

(1) This section does not apply to a parent for a year of income if the parent has a component of adjusted taxable income mentioned in paragraphs 43(1)(b) to (f) for the year of income.

Determinations that taxable income nil or no tax payable

(2) A parent’s taxable income for a year of income is nil if the parent’s taxable income for that year has been determined to be nil under an Income Tax Assessment Act.

(3) A parent’s taxable income for a year of income is also nil if:

(a) the Commissioner has determined under an Income Tax Assessment Act that no tax was payable (before the allowance of any rebate or credit) under that Act on the parent’s taxable income for the year of income; and

(b) either of the following subparagraphs applies in relation to the person:

(i) Part 1 of Schedule 7 to the Income Tax Rates Act 1986 (or any other law prescribed by the regulations for the purposes of this paragraph in relation to the year of income) applied in relation to the parent for the year of income;

(ii) no tax would have been payable (before the allowance of any rebate or credit) under that Act by the person on his or her taxable income if Part 1 of Schedule 7 to the Income Tax Rates Act 1986 (or any other law prescribed by the regulations for the purposes of this paragraph in relation to the year of income) had applied in relation to the parent for the year of income.

(4) Subsections (2) and (3) do not apply in relation to an administrative assessment made in relation to a parent if:

(a) before the administrative assessment is made; but

(b) after the most relevant notice mentioned in subsection (5) or (6) is made;

an assessment is issued under the Income Tax Assessment Act 1936 of the person’s taxable income for the year of income under an Income Tax Assessment Act.

Notices issued under the Income Tax Assessment Act 1936

(5) If a parent has been served a notice under the Income Tax Assessment Act 1936 to the effect that the taxable income of the parent under an Income Tax Assessment Act for a year of income is nil, then:

(a) the parent’s taxable income for that year is taken to have been determined to be nil under an Income Tax Assessment Act; and

(b) if the notice was dated—the determination is taken to have been made on the date of the notice.

(6) If a parent has been served a notice under the Income Tax Assessment Act 1936 to the effect that no tax is payable (before the allowance of any rebate or credit) under an Income Tax Assessment Act on the taxable income of the parent for a year of income, then:

(a) the Commissioner is taken to have determined under the Income Tax Assessment Act that no tax was payable (before the allowance of any rebate or credit) under that Act on the parent’s taxable income for the year of income; and

(b) if the notice was dated—the determination is taken to have been made on the date of the notice.

Higher taxable income to be taken into account

(7) If, after an administrative assessment of child support is made, the assessment (the tax assessment) of a parent’s taxable income is amended (whether or not because of an objection, appeal or review) to determine a taxable income that is higher than nil, the Registrar must amend the administrative assessment on the basis that the parent’s adjusted taxable income for that year of income is, and has always been, the amount worked out as a result of the amended tax assessment.

Date of assessment of a parent’s taxable income taken to be date of notice of the assessment

(8) For the purposes of this section, if:

(b) the notice is dated;

then the assessment is taken to have been made on the date of the notice.

Section not to affect determinations, court orders or consent orders

(9) This section does not prevent:

(a) the Registrar from making any determination under Part 6A (departure determinations); or

(b) a court from making any order under Division 4 of Part 7 (departure orders); or

(c) the making, and acceptance by the Registrar, of a child support agreement that includes provisions that have effect for the purposes of this Part as if they were such an order made by consent.

58 Determination by the Registrar of a parent’s adjusted taxable income

(1) This section applies if a parent is to be assessed in respect of the costs of a child in relation to a child support period (the relevant period) and either of the following apply:

(a) the parent’s taxable income for the last relevant year of income in relation to the relevant period has not been assessed under an Income Tax Assessment Act;

(b) the Registrar is unable to ascertain whether or not the parent’s taxable income for that year has been so assessed.

Information or document in the possession of the Registrar etc.

(2) If:

(a) the Registrar or the Commissioner of Taxation has information (whether oral or written) or a document in his or her possession; and

(b) either:

(i) an amount is specified in that information or document as the parent’s adjusted taxable income for the last relevant year of income; or

(ii) that information or document allows the amount of the parent’s adjusted taxable income for the last relevant year of income to be worked out; and

(c) the Registrar is satisfied that the specified amount, or the amount so worked out, is a reasonable approximation of the parent’s adjusted taxable income for that year;

the Registrar may determine that the specified amount, or the amount so worked out, is the parent’s adjusted taxable income for that year.

Parent not required to lodge a return

(2A) If:

(a) paragraph (1)(a) applies to the parent; and

(b) the Registrar is satisfied that the parent is not required, under section 161 of the Income Tax Assessment Act 1936, to give to the Commissioner of Taxation a return for the last relevant year of income;

the Registrar may determine that the parent’s adjusted taxable income for the last relevant year of income is the amount under subsection (2B).

(2B) The amount under this subsection is the amount that would be equal to one‑third of the annualised MTAWE figure for the relevant June quarter in relation to a child support period if that period were to start on 1 January during the parent’s last relevant year of income in relation to the relevant period.

Parent’s taxable income assessed for the previous year of income

(3) If:

(a) the parent’s taxable income for a year of income has been assessed under an Income Tax Assessment Act; and

(b) that year (the previous year) is the year of income before the last relevant year of income;

the Registrar may determine that the parent’s adjusted taxable income for the last relevant year of income is the amount worked out by multiplying the parent’s adjusted taxable income for the previous year by the ATI indexation factor.

Parent’s taxable income assessed for an earlier year of income

(4) If:

(a) the parent’s taxable income for the previous year has not been assessed under an Income Tax Assessment Act; but

(b) the parent’s taxable income for an earlier year of income has been so assessed;

the Registrar may determine that the parent’s adjusted taxable income for the last relevant year of income is the greater of the following amounts:

(c) the amount worked out by multiplying the parent’s adjusted taxable income for the earlier year of income (or, if the parent’s taxable income has been so assessed for more than one earlier year of income, the most recent of those years) by the ATI indexation factor;

(d) the amount that is equal to two‑thirds of the annualised MTAWE figure for the relevant June quarter in relation to the relevant period.

Other circumstances

(5) If:

(a) subsections (2), (2A), (3) and (4) do not apply in relation to the parent; or

(b) the Registrar decides not to make a determination in relation to the parent under one of those subsections;

the Registrar may determine that the parent’s adjusted taxable income for the last relevant year of income is an amount that is at least two‑thirds of the annualised MTAWE figure for the relevant June quarter in relation to the relevant period.

58AA ATI indexation factor for determinations under section 58

(1) The ATI indexation factor is:

$Start formula start faction AWE amount for the December quarter of the last relevant year of income over AWE amount for the December quarter of the tax return year end fraction end formula$

where:

AWE amount for a December quarter of a year of income means the amount published for the reference period in the quarter by the Australian Statistician in a document titled “Average Weekly Earnings, Australia” (or, if that title changes, in a replacement document) under the headings “Average Weekly Earnings—Trend—Persons—All employees total earnings” (or, if any of those headings change, under any replacement headings).

December quarter of a year of income means the quarter ending on 31 December of that year.

reference period in a December quarter of a year of income means the period described by the Australian Statistician as the last pay period ending on or before the third Friday of the middle month of the quarter.

tax return year means:

(a) if subsection 58(3) applies—the year of income before the last relevant year of income in relation to a child support period; or

(b) if subsection 58(4) applies—the earlier year of income that applies under paragraph 58(4)(c).

(2) The ATI indexation factor is to be calculated to 3 decimal places (rounding up if the fourth decimal place is 5 or more).

(3) If:

(a) the Australian Statistician publishes an AWE amount (the later amount) for a December quarter of a year of income; and

(b) the later amount is published in substitution for an AWE amount for that quarter that was previously published by the Australian Statistician or that was applicable because of subsection (5);

the publication of the later amount is to be disregarded for the purposes of this section.

Determination of amount by Minister

(4) If the Australian Statistician has not published an AWE amount for a December quarter of a year of income before the end of the first 31 March after the end of that quarter, the Minister may, by legislative instrument, determine an amount for that quarter.

(5) If the Minister does so, the AWE amount for that quarter is taken to be the amount determined in the instrument under subsection (4) for that quarter.

58A Subsequently ascertaining components of a parent’s adjusted taxable income

(1) The Registrar must immediately amend an administrative assessment of child support payable by or to a parent in relation to a child support period if:

(a) the assessment was made on the basis of a determination under section 58; and

(b) either:

(i) the Registrar subsequently ascertains the amount of the parent’s adjusted taxable income for the last relevant year of income; or

(ii) the Registrar makes a later determination under section 58; and

(i) if subparagraph (b)(i) applies—the amount that was subsequently ascertained is different from the amount that was determined under section 58; or

(ii) if subparagraph (b)(ii) applies—the later amount that the Registrar determines is different from the earlier amount determined under section 58.

Retrospective determinations

(2) If:

(a) at the time the Registrar is to amend the administrative assessment under this section, the parent could lodge his or her tax return by the date required under Part IV of the Income Tax Assessment Act 1936 (taking into account any deferral under section 388‑55 in Schedule 1 to the Taxation Administration Act 1953); or

(b) paragraph (a) of this subsection does not apply and:

(i) the amount subsequently ascertained, as mentioned in subparagraph (1)(b)(i), is higher than the amount that was determined under section 58; or

(ii) the later amount that the Registrar determines, as mentioned in subparagraph (1)(b)(ii), is higher than the earlier amount determined under section 58; or

(c) neither paragraph (a) nor (b) applies, but circumstances prescribed by the regulations for the purposes of this section apply in relation to the parent;

then the Registrar must immediately amend the administrative assessment for the child support period on the basis that the parent’s adjusted taxable income for that year of income is, and has always been, the amount that was subsequently ascertained or later determined (as the case requires).

Prospective determinations

(3) If subsection (2) does not apply, then the Registrar must immediately amend the administrative assessment for the child support period on the basis that for each later day in the period the parent’s adjusted taxable income for that year of income is the amount that was subsequently ascertained or later determined (as the case requires).

(3A) If, after an administrative assessment of child support is amended under subsection (2) or (3) because of subparagraph (1)(b)(i), the assessment (the tax assessment) of a parent’s taxable income is amended (whether or not because of an objection, appeal or review), the Registrar may further amend the administrative assessment to take account of the amendment to the tax assessment.

Amended tax assessments—retrospective determinations

(3B) An amendment of the administrative assessment under subsection (3A) must be on the basis that the parent’s adjusted taxable income for that year of income is, and has always been, the amount worked out as a result of the amended tax assessment if:

(a) the parent’s adjusted taxable income worked out as a result of the amended tax assessment is higher than the amount determined under section 58; or

(b) the parent lodged his or her income tax return for that year of income with the Commissioner of Taxation on or before the day by which the parent was required to lodge the income tax return for that year (taking into account any deferral under section 388‑55 in Schedule 1 to the Taxation Administration Act 1953) and:

(i) the parent applied for the amendment of the tax assessment on or before the day by which the parent was required to lodge his or her income tax return for that year; or

(ii) the parent applied for the amendment of the tax assessment before the end of 28 days after the parent was given the tax assessment (including an amended tax assessment) by the Commissioner of Taxation; or

(iii) the parent applied for the amendment of the tax assessment before the end of 28 days after the parent becomes aware that the tax assessment is not correct if the parent did not apply for the amendment on or before a day referred to in subparagraph (i) or (ii) because of circumstances beyond the knowledge or control of the parent; or

(iv) the parent did not apply for the amendment of the tax assessment on or before any of the days referred to in subparagraph (i), (ii) or (iii), but the Registrar is satisfied that special circumstances exist.

(3C) An amendment of the administrative assessment under subsection (3A) must be in accordance with subsection (3E) if:

(a) subsection (3B) does not apply; and

(b) the parent’s adjusted taxable income (the later income) worked out as a result of the amended tax assessment is:

(i) higher than the earlier ascertainment of the parent’s taxable income; but

(ii) lower than the amount determined under section 58.

(3D) An amendment of the administrative assessment under subsection (3A) must be in accordance with subsection (3E) if:

(a) subsection (3B) does not apply; and

(b) the parent’s adjusted taxable income (the later income) worked out as a result of the amended tax assessment is lower than both the earlier ascertainment of the parent’s taxable income and the amount determined under section 58; and

(i) the parent applied for the amendment of the tax assessment before the end of 28 days after the parent was given the tax assessment (including an amended tax assessment) by the Commissioner of Taxation;

(ii) the parent applied for the amendment of the tax assessment before the end of 28 days after the parent becomes aware that the tax assessment is not correct if the parent did not apply for the amendment on or before a day referred to in subparagraph (i) because of circumstances beyond the knowledge or control of the parent;

(iii) the parent did not apply for the amendment of the tax assessment on or before either of the days referred to in subparagraph (i) or (ii), but the Registrar is satisfied that special circumstances exist.

(3E) If subsection (3C) or (3D) applies, the amendment of the administrative assessment under subsection (3A) must be on the basis of the later income from the day the earlier ascertainment of the parent’s adjusted taxable income took effect.

Amended tax assessments—prospective determinations

(3F) If none of subsections (3B), (3C) nor (3D) applies, an amendment of the administrative assessment under subsection (3A) for a child support period must be on the basis that for each later day in the period the parent’s adjusted taxable income for that year of income is the amount worked out as a result of the amended tax assessment.

No taxation assessment required

(4) This section applies whether or not the Commissioner of Taxation has made an assessment under an Income Tax Assessment Act of the parent’s taxable income for that year of income.

Subdivision BA—Overseas income

58B Inclusion of overseas income in working out a parent’s adjusted taxable income

For the purposes of working out a parent’s adjusted taxable income for a child for a day in a child support period if the parent is a resident of a reciprocating jurisdiction, a reference in this Division to the parent’s taxable income includes a reference to the parent’s overseas income as determined under this Subdivision.

58C Determination of overseas income if information and documents in Registrar’s possession are sufficient

(1) This section applies if the Registrar possesses sufficient information and documents to determine a parent’s overseas income (whether as a result of seeking information or documents under section 162A or not).

(2) In making an administrative assessment in relation to the parent and a child support period, the Registrar may determine, from the information and documents in the Registrar’s possession, an amount to be the parent’s overseas income for the year of income for the purpose of working out the person’s adjusted taxable income.

58D Determination of overseas income if information and documents in Registrar’s possession are insufficient

(1) This section applies if:

(a) the Registrar does not possess sufficient information and documents to determine a parent’s overseas income; and

(b) despite requesting, under section 162A, information or documents from the parent or from an overseas authority that are necessary to determine the parent’s overseas income, the information or documents requested have not been supplied.

(2) In making an administrative assessment of the child support in relation to the parent and a child support period, the Registrar may determine that the parent’s overseas income for the year of income, for the purpose of working out the parent’s adjusted taxable income, is an amount that the Registrar considers appropriate of at least two‑thirds of the annualised MTAWE figure for the relevant June quarter.

Subdivision C—Child support income determined by reference to parent’s estimate of adjusted taxable income

60 Parent may elect to estimate his or her adjusted taxable income for a year of income

(1) A parent may, before a year of income starts or during a year of income, elect that the parent’s adjusted taxable income for the year of income is to be the amount that applies under subsection (2) or (3) if:

(a) the parent is to be assessed in respect of the costs of a child of the parent for a day in a child support period; and

(b) the amount that would apply under that subsection is not more than 85% of:

(i) the total of the parent’s adjusted taxable income determined in accordance with section 43 for the last relevant year of income for the child support period; or

(ii) an amount that the parent declares is the total of the parent’s adjusted taxable income for the last relevant year of income for the child support period, and the Registrar is satisfied that the declared amount is correct.

Estimate for a whole year of income

(2) If the parent makes the election under subsection (1) before the year of income starts or on the first day of the year of income, the amount is the total of the following amounts (the income component amounts) as estimated by the parent:

(a) the parent’s taxable income for the year, disregarding any assessable FHSS released amount (within the meaning of the Income Tax Assessment Act 1997) that may be included in the parent’s assessable income for the year;

(b) the parent’s reportable fringe benefits total for the year;

(d) the parent’s total net investment loss (within the meaning of the Income Tax Assessment Act 1997) for the year;

(e) the total of the tax free pensions or benefits received by the parent in the year;

(f) the parent’s reportable superannuation contributions (within the meaning of the Income Tax Assessment Act 1997) for the year.

Estimate for a part of a year of income etc.

(3) If the parent makes the election under subsection (1) during the year of income but not on the first day of the year of income:

(a) the parent is to use the method in subsection (4) to work out the amount; and

(b) the parent is to estimate each income component amount for the parent for the period that:

(i) started on the first day of the year of income; and

(ii) ended at the end of the day before the start day for the election.

(4) For the purposes of paragraph (3)(a), the method is as follows:

Method statement

Step 1. Estimate each income component amount for the parent for the period (the remaining period):

(a) starting on the start day for the election; and

(b) ending at the end of the last day of the year of income.

Step 2. Add up those amounts. The result is the partial year income amount.

Step 3. Divide the partial year income amount by the number of days in the remaining period.

Step 4. Multiply the quotient by 365.

(5) The start day for the election must be:

(a) the day on which the parent makes the election; or

(b) the first day of a child support period, so long as that day is not before the day referred to in paragraph (a).

No election if an income amount order is in force

(6) Despite subsection (1), a parent may not make an election if an income amount order is in force in relation to:

(a) the parent; and

(b) if the parent were to make such an election—any part of the period that would be the application period for the election.

How election is made

(1) If:

(a) a parent makes an election under subsection 60(1) relating to a year of income; and

(b) the parent is to be assessed in respect of the costs of a child of the parent for a day in a child support period; and

then, for the purposes of so assessing the parent, the parent’s adjusted taxable income is the amount that applies under subsection 60(2) or 60(3).

(1A) The application period for an election under subsection 60(1) relating to a year of income is the period that:

(a) starts:

(i) if the parent made the election before the year of income started or on the first day of the year of income—on the first day of that year of income; or

(ii) otherwise—on the start day for the election;

unless the election is revoked before that day; and

(b) ends:

(i) at the end of the last day of that year of income; or

(ii) if the parent revokes the election before that day and makes another election (the later election) under subsection 62A(1) relating to the year of income—at the end of the day before the start day for the later election.

(2) Subsection (1) has effect subject to an income amount order that is made after the making of the election that applies in relation to the parent and any part of the application period for the election.

(3) The Registrar must immediately take such action as is necessary to give effect to subsection (1) in relation to any administrative assessment that has been made in relation to the parent (whether by amending the assessment or otherwise).

Method statement

Step 1. Estimate each income component amount for the parent for the period (the remaining period):

(a) starting on the start day for the election made under this subsection; and

(b) ending at the end of the last day of the year of income.

Step 2. Add up those amounts. The result is the partial year income amount.

Step 3. Divide the partial year income amount by the number of days in the remaining period.

Step 4. Multiply the quotient by 365.

Start day

(2) Subject to subsection (3), the start day for the election under subsection (1) must be the day on which the parent makes that election.

(3) If:

(a) an event affecting the accuracy of an estimate on which the earlier election is based has occurred; and

(i) if subsection 60(2) or (3) applied to the earlier election—the amount that applied under that subsection; or

(ii) if the earlier election was made under subsection (1) of this section—the amount worked out under that subsection;

the start day for the election under subsection (1) of this section must be the day on which the event occurred.

How election is made

(a) starts on the start day for the election unless the election is revoked before that day; and

(b) ends:

(i) at the end of the last day of the year of income; or

(2A) Subsection (1) has effect subject to an income amount order that applies in relation to the parent and any part of the application period for the later election.

(d) if the Registrar has made a determination under subsection 64AB(1) in relation to the parent—the parent’s actual adjusted taxable income for the year of income is more than the parent’s determined ATI for that year; and

(e) if, under section 63A, 63B or 63C, the Registrar has amended an assessment of child support payable by or to the parent—the Registrar determines that this section should apply in relation to the parent.

Reconciliation—election for a whole year of income

(2) Subject to this section, if:

(a) subsection 60(2) applied to the income election; and

(b) the parent’s actual adjusted taxable income for the year of income is more than the amount that applied under that subsection;

the parent’s adjusted taxable income for that year is taken to be, and to have always been, the parent’s actual adjusted taxable income for that year.

Reconciliation—election for a part of a year of income

(3) Subject to this section, if:

(a) subsection 60(3) applied to the income election; and

(b) the difference between:

(i) the parent’s actual adjusted taxable income for the year of income; and

(ii) the parent’s applicable year to date income amount for the year of income;

is more than the partial year income amount worked out by the parent under subsection 60(4);

is more than the parent’s estimated ATI amount for the year of income, then the parent’s adjusted taxable income for a day that occurs in the application period of each income election made by the parent is taken to be, and to have always been, the amount worked out for that income election using the method in subsection (4).

Estimated ATI amount

(3) The parent’s estimated ATI amount for the year of income is worked out using the following method:

Method statement

Step 1. For each income election relating to the year of income that had an application period that ended before the last day of the year of income:

(a) if subsection 60(2) applied to the income election—divide the amount that applied under that subsection by 365; or

(b) otherwise—divide the partial year income amount worked out under subsection 60(4) or 62A(1) by the number of days in the remaining period to which the income election related.

Step 2. For each of those income elections, multiply the result of step 1 by the number of days in the application period for the income election.

Step 3. Add up each of the amounts worked out under step 2.

Step 4. Add the result of step 3 and the partial year income amount worked out under subsection 62A(1) for the last income election relating to the year of income that was made by the parent.

Amount for the purposes of subsection (2)

(4) For the purposes of subsection (2), the amount for each income election is worked out using the following method:

Method statement

Step 1. Subtract the parent’s estimated ATI amount from the parent’s actual ATI amount.

Step 2. Divide the result by the total number of days in the application periods for each income election relating to the year of income that was made by the parent. The result is the additional daily rate.

Step 3. For each of those income elections, multiply the additional daily rate by the number of days in the application period for the income election. The result is the underestimated amount for the income election.

Step 4. For each of those income elections, add the underestimated amount for the income election and:

(a) if the income election had an application period that ended before the last day of the year of income—the amount worked out for the income election under step 2 of the method statement in subsection (3); or

(b) otherwise—the partial year income amount worked out under subsection 62A(1) for the income election.

Step 5. For each of those income elections:

(a) divide the result of step 4 by the number of days in the application period for the income election; and

(b) multiply the quotient by 365.

Income amount orders

(5) This section does not apply if an income amount order applies in relation to the parent and any part of an application period for any of the income elections.

(3) If the parent made more than one income election relating to the year of income, the parent has underestimated an income amount in making the income elections if the amount worked out by subtracting:

(a) the parent’s applicable year to date income amount (if any) for the year of income; from

(b) the parent’s actual adjusted taxable income for the year of income;

is at least 110% of the parent’s estimated ATI amount for the year of income worked out under subsection 64A(3).

64AG Amount of penalty

(1) If a parent is liable under subsection 64AF(1) to pay a penalty, the amount of the penalty for each income election made by the parent relating to the year of income is 10% of the difference between:

(a) the administrative assessment of child support made under section 64AA in relation to the parent; and

(b) the administrative assessment of child support that would have been made if it were based entirely on the amount that applied under subsection 60(2) or (3), or that was worked out under subsection 62A(1).

(2) The penalty is a debt due to the Commonwealth by the parent and is due and payable on the issue of the administrative assessment of child support made under section 64AA in relation to the parent.

64AH Remission of penalty

(1) The Registrar may remit the whole or a part of a penalty that a parent who made an income election is liable to pay under subsection 64AF(1) if:

(a) the parent underestimated an income amount in making the income election because of an amendment of an Income Tax Assessment Act, or because of a ruling or determination under that Act; or

(b) the parent underestimated an income amount in making the income election for some other reason, and the Registrar is satisfied that it would be fair and reasonable in the circumstances to remit the whole or that part of the penalty.

(2) If the Registrar makes a decision to remit only part of the penalty, or not to remit any part of the penalty, the Registrar must give written notice of the decision to the parent by whom the penalty is, or but for the remission would be, payable.

(3) The notice must include, or be accompanied by, a statement to the effect:

(a) that the parent may, subject to the Registration and Collection Act, object to the decision (the original decision); and

(b) that if the parent is aggrieved by a later decision on an objection to the original decision, he or she may, subject to that Act and the AAT Act, apply to the AAT for review of the later decision.

(4) A contravention of subsection (3) in relation to a decision does not affect the validity of the decision.

Division 8—Provisions relating to the making of assessments

Subdivision A—Preliminary

64B Simplified outline

The following is a simplified outline of this Division:

• In making an administrative assessment, the Registrar may act on the basis of the documents and information in his or her possession.

• In some cases, the Registrar may assess, under this Division, the annual rate of child support for a child that is payable by a parent who is not receiving an income support payment.

• The Registrar may also assess, under this Division, the annual rate of child support payable by a parent for all the children in a child support case as the minimum annual rate of child support.

• Subdivision C contains rules relating to making administrative assessments (such as when the Registrar can amend an administrative assessment and when the Registrar needs to give a notice of assessment).

Subdivision B—Annual rates of child support for low income parents and minimum annual rates of child support

65A Annual rate of child support for low income parents not on income support

Assessment of annual rate

(1) The Registrar must assess an annual rate of child support payable by a parent for a child for a day in a child support period as the rate specified in subsection (2) if:

(a) the parent did not receive an income support payment during the last relevant year of income; and

(b) the following amount is less than the pension PP (single) maximum basic amount:

(i) if subparagraph (ii) does not apply—the parent’s adjusted taxable income determined in accordance with section 43 for the last relevant year of income for the child support period;

(ii) if the day occurs in the application period for an income election made by the parent—the amount that applied under subsection 60(2) or (3), or that was worked out under subsection 62A(1); and

How much is the annual rate

(2) The annual rate of child support payable is $1060.

Note: The annual rate of child support specified in subsection (2) is indexed under section 153A.

(3) The Registrar must not assess the total annual rate of child support payable by a parent under subsection (1) (including any child support that is not actually payable because of subsection 40B(1)) for a day in a child support period as more than 3 times the rate specified in subsection (2).

(4) If an annual rate of child support is payable by a parent under subsection (1) (including any child support that is not actually payable because of subsection 40B(1)) for more than 3 children for a day in a child support period, then the annual rate of child support payable by the parent for each child for a day in the child support period is:

$Start formula start fraction 3 times Annual rate specified in subsection open bracket 2 close bracket over Total number of children for whom child support is payable by the parent under subsection start bracket 1 close bracket end fraction end formula$

(4A) For the purposes of subsection (4), if a parent is liable to pay child support for one or more children under an administrative assessment under the law of a reciprocating jurisdiction, then that child support is taken to be payable by the parent for those children under subsection (1).

Paying the annual rate to more than one person

(5) If, (disregarding section 40B) the rate under subsection (2) or (4) would be payable for a child to:

(a) a parent and a non‑parent carer of the child; or

(b) 2 non‑parent carers of the child;

then, subject to section 40B, the annual rate of child support for the child worked out under this section is payable in accordance with section 40A.

Note: Under section 40B, a non‑parent carer of a child is not entitled to be paid child support unless he or she applies under section 25A in relation to the child.

65B Application for section 65A not to apply

(1) If the Registrar makes an assessment of an annual rate of child support payable by a parent for a day in a child support period under section 65A:

(a) the parent may apply to the Registrar for the section not to apply; or

(b) the parent is taken to have applied to the Registrar for the section not to apply if, immediately before the end of the previous child support period, the section did not apply because of a determination under this section.

(2) The parent making the application must provide evidence to the Registrar concerning the parent’s income (within the meaning of subsection 66A(4)) to demonstrate that his or her current income is:

(a) less than the pension PP (single) maximum basic amount; and

(b) that it would be unjust and inequitable to expect him or her to pay the amount assessed under this section.

(3) An assessment issued by the Commissioner of Taxation for the last relevant year of income shall not be sufficient evidence of the income of the parent for the purposes of this section.

(4) If the parent makes an application, the Registrar may determine in writing that the section not apply to the parent if the parent’s current income (within the meaning of subsection 66A(4)) is less than the pension PP (single) maximum basic amount and it would be unjust and inequitable to expect him or her to pay the amount assessed under this section.

Note: If the Registrar refuses to grant an application under this section, the Registrar must serve a notice on the applicant under section 66C.

(5) The Registrar must specify the day in the child support period on which the section ceases to apply to the parent. The day may be any day from the first day of the child support period on which an annual rate of child support under section 65A became payable by the parent.

66 Minimum annual rate of child support

Assessment of annual rate

(1) The Registrar must assess the total of the annual rates of child support payable by a parent for all the children in a child support case for a day in a child support period as the minimum annual rate of child support for the child support period if:

(a) the parent does not have at least regular care of at least one of the children in the child support case for the day; and

(b) the total payable by the parent for all the children in the child support case would (apart from this section) be assessed as less than the minimum annual rate of child support for the child support period.

Note: The Registrar must not make an assessment under this subsection in certain cases (see subsections (2) and (8)).

(2) To avoid doubt, the Registrar must not make an assessment in respect of a parent whose annual rate of child support could be assessed under section 65A (low income parents not on income support) unless the Registrar has determined under section 65B that section 65A does not apply.

When assessment applies

(4) An assessment in respect of a parent covered by paragraph (1)(b) applies to each day in the period:

(a) beginning on the first day in the child support period on which the total payable by the parent in respect of the child support case would (apart from this section) be assessed as less than the minimum annual rate of child support for the child support period; and

(b) ending:

(i) if the parent would be so assessed until the end of the child support period—at the end of the child support period; or

(ii) otherwise—28 days after the day on which the person would cease to be so assessed (even if that day is after the end of the child support period).

How much is the minimum annual rate

(5) The minimum annual rate of child support is $320.

Note: The minimum annual rate of child support specified in subsection (5) is indexed under section 153A.

(6) If:

(a) the Registrar makes an assessment in respect of a parent under subsection (1); and

(b) the parent is assessed (whether under subsection (1) or otherwise) for a day in a child support period in respect of the costs of children in more than 3 child support cases;

then the annual rate of child support payable by the parent for a day in the child support period for a particular child support case is:

$Start formula start fraction 3 times Minimum annual rate of child support over Total number of parent's child support cases end fraction end formula$

(6A) For the purposes of subsection (6), if a parent is liable to pay child support for one or more children for a day under an administrative assessment under the law of a reciprocating jurisdiction, then the parent is taken to be assessed for the day in respect of the costs of children in a child support case.

Paying the minimum annual rate to more than one person for a single child support case

(7) If the rate worked out under subsection (5) or (6) is payable by a parent for a child support case to:

(a) the parent of the children to whom the case relates and to one or more non‑parent carers of those children; or

(b) 2 or more non‑parent carers of those children;

then:

(c) if 2 or more persons have equal percentages of care of the children, and those percentages are the highest percentages—each of those persons is entitled to be paid an equal proportion of the annual rate of child support that is payable by the parent; and

(d) otherwise—only the person who has the highest percentage of care of the children is entitled to be paid the annual rate of child support that is payable by the parent.

Registrar not to make minimum rate assessment in certain cases

(8) The Registrar must not make an assessment under subsection (1) in relation to the child support payable by a parent:

(a) in accordance with a determination made under Part 6A (departure determinations); or

(b) in accordance with an order made under Division 4 of Part 7 (departure orders); or

(c) in accordance with provisions of a child support agreement that have effect, for the purposes of this Part, as if they were such an order made by consent.

Definition of income support payment

(9) In this Act:

income support payment:

(a) has the meaning given by subsection 23(1) of the Social Security Act 1991; and

(b) includes a payment under the ABSTUDY scheme that includes an amount identified as living allowance, being an allowance that is paid at the maximum basic rate.

66A Registrar may reduce an assessment to nil in certain cases

(1) If the Registrar has made an assessment under section 66 in respect of the annual rate of child support payable by a parent for all the children in a child support case for a day in a child support period, the Registrar may, on an application made by the parent that:

(a) is in accordance with the regulations; and

(b) either:

(i) nominates the whole (the nominated period) of that child support period (if the first day of that child support period is the day referred to in paragraph 66(4)(a)); or

(ii) nominates a part (the nominated period) of that child support period, being a part that is at least 2 months and that begins on or after the day referred to in paragraph 66(4)(a);

reduce the annual rate of child support payable by the parent for those children for the nominated period to nil. This subsection is subject to subsection (3C).

Note: If the Registrar refuses to grant an application under this section, the Registrar must serve a notice on the applicant under section 66C.

(2) The Registrar must not grant an application under subsection (1) unless the Registrar is satisfied that the amount worked out under subsection (3) is less than the amount worked out under subsection (3A).

(2A) For the purposes of subsection (2), a parent is taken to have a child support case if the parent is liable to pay child support for one or more children under an administrative assessment under the law of a reciprocating jurisdiction.

(3) The amount for the purposes of this subsection is:

$Start formula start fraction Parent's income for the nominated period over Number of days in the nominated period end fraction times 365 end formula$

(3A) The amount for the purposes of this subsection is:

Start formula The total number of the parent's child support cases times The minimum annual rate of child support for the child support period end formula

(3B) For the purposes of subsection (3A), a parent is taken to have a child support case if the parent is liable to pay child support for one or more children under an administrative assessment under the law of a reciprocating jurisdiction.

(3C) A reduction under subsection (1) has no effect in relation to a day to which the assessment under section 66 does not apply.

Note: Subsection 66(4) deals with when an assessment under section 66 applies.

(4) In this section:

income, in relation to a person, means:

(a) any money earned, derived or received by the parent for his or her own use or benefit, other than money earned, derived or received in a manner, or from a source, prescribed by the regulations for the purposes of this paragraph; or

(b) a periodical payment by way of a gift or allowance, other than a payment of a kind prescribed by the regulations for the purposes of this paragraph.

66B Amendment of assessment made under section 65B or 66A

The Registrar may amend an assessment at any time if:

(a) either:

(i) under section 65B, the Registrar has determined that section 65A does not apply to a parent; or

(ii) under section 66A, the Registrar has reduced an annual rate of child support payable by a parent to nil; and

(b) the Registrar becomes satisfied that the parent does not satisfy the condition in subsection 65B(4) or 66A(2) (as the case requires).

66C Notice to be given to unsuccessful applicant

(1) If the Registrar refuses to grant an application under section 65B or 66A, or amends an assessment in accordance with section 66B, the Registrar must serve written notice of the decision on the parent.

(2) The notice must include, or be accompanied by, a statement to the effect:

(a) that the parent may, subject to the Registration and Collection Act, object to the particulars of:

(i) the assessment in relation to which the unsuccessful application was made; or

(ii) the assessment that was amended;

(as the case requires); and

(b) that if the parent is aggrieved by the decision on the objection, he or she may, subject to that Act and the AAT Act, apply to the AAT for review of the decision.

(3) A contravention of subsection (2) in relation to a decision does not affect the validity of the decision.

Subdivision C—Making administrative assessments

66D How assessment is to be made

In making an administrative assessment, the Registrar may act on the basis of the documents and information in his or her possession, and is not required to conduct any inquiries or investigations into the matter or to require (whether under this Act or otherwise) the giving of any information or the production of any document.

67 Assessment to relate to all children for whom child support is payable by parent

(1) If child support is payable by a parent to a person for 2 or more children for a day in a child support period, any administrative assessment of the child support payable by the parent in relation to the day is to relate to all of the children and not to any of the children separately.

(2) Subsection (1) applies whether or not the child support is payable because of:

(a) the acceptance by the Registrar of 2 or more separate applications for administrative assessment made otherwise than in the same form; or

(b) the acceptance by the Registrar of 2 or more child support agreements made otherwise than in the same document; or

(c) the acceptance by the Registrar of an application for administrative assessment and of an application for acceptance of a child support agreement.

(3) Subsection (1) does not require a single administrative assessment to be made of the child support payable by a parent to 2 or more other persons.

67A Offsetting of child support liabilities

The annual rate of child support that would, apart from this section, be payable for a child or children in a child support case, for a day in a child support period, by one parent to the other parent is to be reduced (but not below nil) by the annual rate of child support that would, apart from this section, be payable to that parent in relation to that day by the other parent for the child or the children in the child support case.

68 Assessment to relate to whole or part of single child support period

(1) An administrative assessment of child support is to relate to all the days, or some of the days, of a single child support period.

(2) Subsection (1) does not prevent a single notice of assessment under section 76 dealing with more than one administrative assessment.

69 Conversion of annual rates into daily rates of payment

If the Registrar assesses the annual rate of child support payable by a parent for a child or children in a child support case, for a day in a child support period, the Registrar must, in accordance with the regulations, convert that annual rate into a daily rate and specify both the annual and daily rates in the notice of assessment given under section 76 in relation to the assessment.

70 Evidence relating to assessments

(1) The production of a notice of administrative assessment, or of a document signed by the Registrar that appears to be a copy of a notice of administrative assessment, is prima facie evidence:

(a) of the proper making of the administrative assessment; and

(b) except in proceedings to which subsection (1A) applies—that all the particulars of the notice of administrative assessment are correct.

(1A) For the purposes of paragraph (1)(b), this subsection applies to any of the following proceedings relating to the administrative assessment:

(a) an AAT first review or AAT second review for the purposes of the Registration and Collection Act;

(b) an appeal under Part IVA of the AAT Act in relation to such a review.

(2) The production of a document signed by the Registrar that appears to be a copy of, or an extract from, any return or notice of administrative assessment is evidence of the matters in the document to the same extent as the original would be if it were produced.

71 Assessment for part of a child support period

In making an administrative assessment of the annual rate of child support payable for days in a period (the part period) that is not a whole child support period, the Registrar may apply this Act as if the beginning and end of the part period were the beginning and end respectively of a child support period.

72 Validity of assessments

Except in an AAT first review or AAT second review within the meaning of the Registration and Collection Act, or an appeal under Part IVA of the AAT Act in relation to such a review, the validity of an assessment is not affected because any of the provisions of this Act have not been complied with.

73 Assumptions as to future events

In assessing the annual rate at which child support is payable for a day in the future, the Registrar may act on the assumption that the state of affairs known to the Registrar at the time the assessment is made will remain unchanged on that day.

73A Registrar becoming aware of relevant dependent child

(1) If:

(a) an administrative assessment of child support is in force in relation to a parent; and

(b) the Registrar is later notified, or otherwise becomes aware, of the fact that the parent has a relevant dependent child who was not taken into account for the purposes of making the assessment;

then, for the purposes of working out the parent’s relevant dependent child amount under section 46, the parent is taken to have the relevant dependent child:

(c) if the Registrar was notified, or otherwise became aware, of the fact that the child is a relevant dependent child of the parent within 28 days after the day on which the child became such a child—on and from the day the child became such a child; or

(d) if paragraph (c) does not apply and the Registrar was notified, or otherwise became aware, of the fact within 28 days after giving a notice under section 34 (giving notice of successful application)—on and from the day on which the application was made; or

(e) if neither paragraph (c) nor (d) applies—on and from the day the Registrar was notified, or otherwise became aware, of the fact that the child is a relevant dependent child of the parent.

(2) If the parent is a resident of a reciprocating jurisdiction, subsection (1) has effect as if the references in paragraphs (1)(c) and (d) to 28 days were references to 90 days.

74 Registrar to give effect to happening of child support terminating events etc.

(1) If:

(a) child support is payable for a child; and

(b) the Registrar is notified of, or otherwise becomes aware of:

(i) the happening of a child support terminating event in relation to the child, a liable parent, or a carer entitled to child support, or all 3; or

(ii) the happening of an event or change of circumstances that affects the annual rate at which the child support is payable under this Act;

the Registrar must immediately take such action as is necessary to take account of the happening of the event or change of circumstances (whether by amending any administrative assessment or otherwise).

(2) Nothing in subsection (1) is to be taken to prevent the Registrar from taking such action as the Registrar considers appropriate to take account of the likely happening of an event or change of circumstances of which the Registrar is notified or otherwise becomes aware (whether by amending any administrative assessment or otherwise).

74A Date of effect of change in care

If:

(a) child support is payable for a child; and

(b) a determination of a responsible person’s percentage of care for the child is revoked; and

(ba) another such determination (the later determination) is made in relation to the responsible person; and

(c) as a result, the Registrar amends an administrative assessment under section 75 to alter the annual rate at which the child support is payable for the child;

the altered annual rate is to apply on and from the first day in a child support period to which the responsible person’s percentage of care under the later determination applies.

Note: If the Registrar becomes aware of a relevant dependent child who was not taken into account for the purposes of making an assessment, the Registrar must take action in accordance with section 73A.

75 Amendment of assessments

(1) The Registrar may, at any time, amend any administrative assessment by making such alterations and additions as the Registrar considers necessary to give effect to this Act or the Registration and Collection Act.

(2) However, if the amendment relates to a responsible person’s percentage of care for a child, the Registrar must not amend an administrative assessment unless:

(a) the amendment relating to the responsible person’s percentage of care for the child would cause the person’s cost percentage for the child to change; or

(d) the child is a relevant dependent child and the Registrar has become aware that the child was not taken into account for the purpose of making the assessment.

(3) Subsection (1) has effect despite the fact that:

(a) child support has been paid under the administrative assessment; or

(b) the child support period, or the part of the child support period, to which the administrative assessment relates has ended; or

(c) proceedings against or in relation to the administrative assessment are pending in the AAT or in a court having jurisdiction under this Act, the Registration and Collection Act or the AAT Act.

(4) Without limiting subsection (1), the Registrar may amend any administrative assessment for the purpose of:

(a) correcting any error or mistake (whether or not made by the Registrar); or

(b) correcting the effect of any false or misleading statement made to the Registrar; or

(c) giving effect to the happening of a child support terminating event in relation to a child, the liable parent, the carer entitled to child support, or all 3; or

(d) giving effect to the happening of an event or change of circumstances that, under this Act or the Registration and Collection Act, affects the annual rate at which child support is or was payable; or

(e) giving effect to the acceptance of a child support agreement by the Registrar; or

(f) giving effect to a decision or order of the AAT or of a court having jurisdiction under this Act, the Registration and Collection Act or the AAT Act.

(5) Where a provision of this Act or the Registration and Collection Act expressly authorises the Registrar to amend an administrative assessment, that provision does not by implication limit the power of the Registrar (whether under this section or otherwise) to amend the assessment.

(6) Except as otherwise expressly provided in this Act or the Registration and Collection Act, every amended administrative assessment is to be taken to be an administrative assessment for all the purposes of this Act and the Registration and Collection Act.

76 Notice of assessment to be given

(1) When the Registrar makes an administrative assessment, the Registrar must immediately give written notice of the assessment to the liable parent and the carer entitled to child support.

(2) The notice must (in addition to specifying the matters that section 69 (daily rate conversion) requires to be specified in the notice) specify at least the following matters:

(a) the adjusted taxable income, and child support income, of any parent (the assessed parent) who was assessed in respect of the costs of the children in the child support case to which the assessment relates;

(b) the names and dates of birth of those children;

(d) the number and age ranges of the other children in other child support cases (if any) of an assessed parent;

(e) an assessed parent’s, and non‑parent carer’s, percentage of care for each child in the child support case to which the assessment relates;

(g) the costs of each child in the child support case to which the assessment relates;

(ga) if a child support agreement includes lump sum payment provisions, or if a court has made an order under section 123A, in respect of the children in the child support case to which the assessment relates:

(i) the amount of the lump sum payment specified in the agreement or order; and

(ii) the amount of any remaining lump sum payment (within the meaning of the Registration and Collection Act); and

(iii) any annual rate and daily rate of child support that remains payable under section 78 of this Act after taking into account any remaining lump sum payment that will be credited under section 69A of the Registration and Collection Act;

(h) such other matters as are prescribed.

(2AA) For the purposes of paragraph (2)(d), a parent is taken to have a child support case if the parent is liable to pay child support for one or more children under an administrative assessment under the law of a reciprocating jurisdiction.

(2A) Despite subsection (2), if an administrative assessment is affected either:

(a) by an order made by a court under Division 4 of Part 7; or

(b) by the provisions of a child support agreement;

the Registrar is not required to specify any matter referred to in that subsection that is not relevant to the making of the assessment.

(3) The notice must also include, or be accompanied by, statements of the following kinds:

(a) a statement that specifically draws the attention of the liable parent and the carer entitled to child support to the right:

(i) to object, subject to the Registration and Collection Act, to particulars of the assessment; and

(ii) if aggrieved by the decision on an objection to particulars of the assessment (no matter who lodges the objection but subject to that Act and the AAT Act), to apply to the AAT for review of the decision;

(c) a statement that specifically draws the attention of the liable parent and the carer entitled to child support to the right to apply to the Registrar for a determination under Part 6A having the effect that the provisions of this Act relating to administrative assessment of child support will be departed from in relation to a child in the special circumstances of the case;

(ca) a statement that specifically draws the attention of the liable parent and the carer entitled to child support to the right to apply to a court having jurisdiction under this Act for an order under section 123A that the liable parent provide child support for the child in the form of a lump sum payment to be credited against the amount payable under the liability of the liable parent under any relevant administrative assessment;

(d) a statement that specifically draws the attention of the liable parent and the carer entitled to child support to the right, subject to the Family Law Act 1975, to apply to a court having jurisdiction under this Act for an order under section 124 that a parent provide child support for the child otherwise than in the form of periodic amounts.

Division 9—Liability to pay child support as assessed

76A Simplified outline

The following is a simplified outline of this Division:

• The amount of child support payable for a child or children for a day in a child support period is the daily rate specified in the notice of assessment.

77 Effect of assessment

(1) This section applies if the Registrar:

(a) assesses the annual rate of child support payable for a child or children in a child support case, for a day in a child support period, by a liable parent to a carer entitled to child support; and

(b) converts the annual rate into a daily rate and specifies both rates in a notice of assessment given under section 76 in relation to the assessment.

(2) Child support is payable for the child or children by the liable parent to the carer entitled to child support for each day in the child support period.

(3) The amount of child support payable for the child or children for the day by the liable parent to the carer entitled to child support is the amount of the daily rate specified in the notice of assessment.

78 When amounts of child support due and payable

(1) An amount of child support payable by a liable parent in relation to a day in any calendar month is due and payable on the later of the following days:

(a) the seventh day of the following calendar month;

(b) the 30th day after the liable parent was given a notice of assessment under section 76 specifying the annual and daily rates of child support in relation to that day.

Note: Section 66 of the Registration and Collection Act deals with when child support debts become due and payable.

(2) An amount payable under subsection (1), in relation to a day in a calendar month in a year of income, is taken to be paid at the time that the amount becomes due and payable, to the extent that a remaining lump sum payment will be credited, under section 69A of the Registration and Collection Act, at the end of the year of income against that amount.

79 Recovery of amounts of child support

An amount of child support due and payable by a liable parent to a carer entitled to child support is a debt due and payable by the liable parent to the carer, and may be sued for and recovered in:

(a) a court having jurisdiction for the recovery of debts up to the amount of the child support; or

(b) a court having jurisdiction under this Act.

Note: Amounts covered by section 30 of the Registration and Collection Act are debts due to the Commonwealth.

Part 6—Consent arrangements

Division 1—Preliminary

80A Simplified outline

The following is a simplified outline of this Part:

• Parents (and non‑parent carers) of a child can, using a child support agreement, agree between themselves the child support that is to be payable for the child.

• There are 2 sorts of agreements. The first is a binding child support agreement. Each party to the agreement must have received legal advice before entering the agreement, and must also receive legal advice before terminating the agreement.

• The second sort of agreement is a limited child support agreement. An administrative assessment must be in place before a limited child support agreement can be accepted by the Registrar. The annual rate of child support payable under the agreement must be at least the annual rate of child support otherwise payable under this Act.

• Agreements may include provisions that state that child support is to be payable otherwise than in the form of periodic amounts. There are 2 main kinds of such provisions:

(a) non‑periodic payment provisions, under which lump sum payments and other non‑periodic payments (such as school fees) may be made; and

(b) lump sum payment provisions, under which lump sum payments may be made.

• Payments made under non‑periodic payment provisions reduce the annual rate of child support payable.

• Payments made under lump sum payment provisions are credited against the amount payable under the liability of a party to the agreement (rather than reducing the annual rate of child support payable).

80B Cases in relation to which Part applies

This Part applies where the parents of an eligible child, or a parent or the parents of an eligible child and a non‑parent carer of the child, want to give effect to an agreement between themselves in relation to child support payable for the child.

(2) If there is a party to the agreement in relation to whom subsection (1) does not apply, that party is to be disregarded for the purposes of this Act.

(3) Subsection (2) does not affect the operation of the agreement in relation to that party for any other purpose.

84 Provisions that may be included in agreements

Provisions that may be included

(1) An agreement is a child support agreement only if it includes one or more of the following kinds of provisions:

(a) provisions under which a party is to pay child support for a child to another party in the form of periodic amounts paid to the other party;

(b) provisions under which the rate at which a party is already liable to pay child support for a child to another party in the form of periodic amounts paid to the other party is varied;

(c) provisions agreeing between parties any other matter that may be included in an order made by a court under Division 4 of Part 7 (departure orders);

(d) provisions (the non‑periodic payment provisions) that state:

(i) that a party (the liable party) is to provide child support for a child to another party otherwise than in the form of periodic amounts; and

(ii) that the annual rate of child support payable for the child by the liable party under any relevant administrative assessment is to be reduced, in the manner specified under subsection (6), by the amount of child support to be provided by the liable party;

(e) provisions (the lump sum payment provisions) that meet the requirements of subsection (7) and that state:

(i) that a party (the liable party) is to provide child support for a child to another party in the form of a lump sum payment (including by way of transfer or settlement of property); and

(ii) that the lump sum payment is to be credited against the amount payable under the liable party’s liability under the relevant administrative assessment;

(f) provisions under which a party is to provide child support for a child to another party otherwise than in the form of periodic amounts and that are not non‑periodic payment provisions or lump sum payment provisions;

(g) provisions under which the liability of a party to pay or provide child support for a child to another party is to end from a specified day.

(2) The agreement may include more than one kind of provision in relation to different parts of a child support period and different child support periods.

Other kinds of provisions not to have effect

(3) If the agreement also includes provisions of a kind not referred to in subsection (1), those provisions do not have effect for the purposes of this Act.

(4) Subsection (3) does not affect the operation of provisions of the kind referred to in that subsection for any other purpose.

Agreement may also be parenting plan, maintenance agreement or financial agreement

(5) Without limiting subsection (4), nothing in this Part is to be taken to prevent the same document being both a child support agreement and:

(a) a parenting plan; or

(b) a maintenance agreement or financial agreement under the Family Law Act 1975; or

Additional requirements of agreements with non‑periodic payment provisions

(6) If an agreement includes provisions of the kind referred to in paragraph (1)(d), the statement referred to in subparagraph (1)(d)(ii) must specify either:

(a) that the annual rate of child support payable under the administrative assessment is to be reduced by a specified amount that represents an annual value of the child support payable; or

(b) that the annual rate of child support payable under the administrative assessment is to be reduced by 100% or another specified percentage that is less than 100%.

Note: Non‑periodic payment provisions are taken to have effect as if they were a statement made by a court under section 125 in an order made under section 124 (see subsection 95(3)).

Additional requirements etc. of agreements with lump sum payment provisions

(7) If an agreement includes provisions of the kind referred to in paragraph (1)(e), the provisions meet the requirements of this subsection if:

(i) is specified in the agreement; and

(ii) equals or exceeds the annual rate of child support payable for the child under the administrative assessment.

Note: If an agreement includes provisions of the kind referred to in paragraph (1)(e) (lump sum payment provisions), the lump sum payment is credited under section 69A of the Registration and Collection Act against the amount payable under the liable party’s liability (rather than reducing the annual rate of child support payable under the administrative assessment).

(8) An agreement that includes lump sum payment provisions may also state that the lump sum payment is to be credited against 100%, or another specified percentage that is less than 100%, of the amount payable under the liability.

Note: If an agreement does not specify a percentage, the lump sum payment is credited against 100% of the amount payable under the liability (see section 69A of the Registration and Collection Act).

85 Child support agreement must not provide for person who is not eligible carer to be paid child support

(1) An agreement is not a child support agreement in relation to a child if (disregarding section 67A) the agreement provides that a party to the agreement is to pay or provide child support for the child to another party for a period during which the party is not an eligible carer of the child.

(2) Subsection (1) does not affect the operation of the agreement for any other purpose.

Division 2A—Other rules relating to child support agreements

86 Suspension of child support agreements when person is not eligible carer

(1) A child support agreement is suspended in relation to a child by force of this section on a day if:

(a) a party (the former carer) to the agreement who is entitled to be paid or provided child support for the child (disregarding section 67A) under the agreement is not an eligible carer of the child on that day; and

(b) the period (including that day) during which the former carer has not been an eligible carer of the child is:

(i) 28 days or less; or

(ii) if subsection (2) applies—26 weeks or less; and

(d) the former carer would (apart from this section) continue to be entitled to be paid or provided child support for the child under the agreement in respect of the day despite ceasing to be an eligible carer.

Note: The agreement may continue without suspension in relation to other children to whom the agreement relates if the person does not cease to be an eligible carer of those children (see section 87).

(2) The former carer may cease to be an eligible carer of the child for up to 26 weeks under subparagraph (1)(b)(ii) if:

(a) the child support agreement provides that the agreement is to be suspended if a party to the agreement ceases to be an eligible carer of the child for a period of more than 28 days; or

(b) after the former carer ceases to be an eligible carer, each of the parties to the agreement notifies the Registrar, before the end of the 26 week period, that the parties to the agreement want the agreement suspended for more than 28 days; or

86A Apportioning amounts payable under child support agreements

(1) This section applies if:

(a) an agreement is made in the same document in relation to 2 or more children; and

(b) the agreement does not explicitly provide, and it is not possible to work out, the amount payable under the agreement in relation to each of the children to whom the agreement relates.

(2) The agreement is taken to provide that the total amount payable under the agreement in relation to each of the children to whom the agreement relates is worked out using the following formula:

$Start formula start fraction Total amount payable under the agreement over The total number of children to whom the agreement relates end fraction end formula$

(3) To avoid doubt, if the agreement ceases to relate to a child, the amount worked out under subsection (2) continues to apply in relation to each of the remaining children to whom the agreement relates.

87 Agreement may be made in relation to 2 or more children etc.

(1) If an agreement is made in the same document in relation to 2 or more children, the document may be treated as if it contained separate agreements for each of the children.

(2) If:

(a) agreement is made in the same document in relation to a child or 2 or more children; and

(b) child support is to be payable to or by 2 or more parties to the agreement for the child or any of the children;

the document may be treated as if it contained separate agreements made in relation to the child or each of the children by each of the parties to or by whom child support is to be payable.

Division 3—Applications to Registrar for acceptance of child support agreements

90 Application for 2 or more separate agreements may be made in same form

If application is made in the same form for acceptance of 2 or more agreements made in relation to a child or 2 or more children (whether or not the agreements have been made in the same document), the form may be treated as if it contained separate applications for each of the agreements.

Division 4—Decisions on applications

91 How decision is to be made

In determining whether an agreement made in relation to a child is an agreement referred to in paragraph 88(a), the Registrar may act on the basis of the application made to the Registrar for acceptance of the agreement, the documents accompanying the application and the agreement itself, and is not required to conduct any inquiries or investigations into the matter.

92 Decision on application

(1) Subject to this section, if the Registrar is satisfied that an application made to the Registrar for acceptance of an agreement made in relation to a child has been properly made, the Registrar must accept the agreement.

(2) If the Registrar is not so satisfied, the Registrar may refuse to accept the agreement.

(3) The Registrar must refuse to accept a limited child support agreement if, immediately before the application for acceptance of the agreement is made, no administrative assessment is in force in relation to the child.

(5) The Registrar must refuse to accept the agreement if:

(a) immediately before the application is made, an administrative assessment is in force in relation to the child and the 2 parties to the agreement; and

(b) the application for administrative assessment was made, in accordance with paragraph 29B(1)(b), by an overseas authority of a reciprocating jurisdiction on behalf of the one of the parties to the agreement; and

93 Liability to pay child support arises on acceptance of application where child support not already payable etc.

(1) If:

(a) the Registrar accepts a child support agreement made in relation to a child; and

(i) child support is not already payable for the child; or

(ii) child support is already payable by a person to another person for the child, but child support is to be paid or provided under agreement for the child otherwise than by the first‑mentioned person to the other person;

then, subject to subsection (1A):

(c) the acceptance of the agreement by the Registrar has the same effect (as provided by this section) as the acceptance by the Registrar of an application for administrative assessment of child support for the child; and

(d) a person to whom child support is to be paid or provided under the agreement is a carer entitled to child support in relation to the child; and

(e) a person by whom child support is to be paid or provided under the agreement to the carer entitled to child support is a liable parent in relation to the child and the carer entitled to child support; and

(f) child support is payable for the child by the liable parent to the carer entitled to child support; and

(g) the child support is payable from the day on which the application was made to the Registrar for acceptance of the agreement; and

(h) the child support is payable until the earlier of the following days:

(i) the day immediately before the day on which a child support terminating event happens in relation to the child, the carer entitled to child support, the liable parent or all 3 of them;

(ii) the day immediately before the day on which the agreement is terminated under section 80D or 80G.

(1A) Despite paragraphs (1)(g) and (h), child support is not payable for a child under the agreement for a day if the agreement is suspended in relation to the child under section 86 on that day.

(2) The Registrar must assess under this Act the annual rate of the child support payable by the liable parent to the carer entitled to the child support for the child for the days in the child support period that starts on the day on which the application was made to the Registrar for acceptance of the agreement. The Registrar must do so as quickly as practicable.

Note 1: The Registrar must assess, under section 34B, the annual rate of child support payable under an agreement if an annual rate of child support is already payable and the agreement is to affect that annual rate.

Note 2: If the Registrar makes an assessment under this section, the Registrar must make a provisional notional assessment under section 146B.

(3) In making any administrative assessment in relation to the child, the carer entitled to child support and the liable parent, the Registrar must act in accordance with section 95 (Effect of certain provisions of accepted child support agreements).

94 Registrar to take action to give effect to accepted child support agreement or termination agreement etc.

(1) After the Registrar accepts a child support agreement made in relation to a child, the Registrar must immediately take such further action (if any) as is necessary to give effect to the agreement.

Note: After accepting the agreement, section 34B or 93 or Part 5 might require the Registrar to assess an annual rate of child support payable.

(2) In making any administrative assessment in relation to the child, the Registrar must act in accordance with section 95 (effect of certain provisions of accepted child support agreements).

(3) After the Registrar accepts a termination agreement, or a written agreement referred to in paragraph 80G(1)(b), the Registrar must immediately take such further action (if any) as is necessary to give effect to the agreement.

95 Effect of certain provisions of accepted child support agreements

(1) This section applies in relation to a child support agreement that has been accepted by the Registrar.

(2) If the agreement includes:

(a) provisions under which a party is to pay child support for a child to another party in the form of periodic amounts paid to the other party; or

(b) provisions under which the rate at which a party is already liable to pay child support for a child to another party in the form of periodic amounts paid to the other party is varied; or

(c) provisions agreeing between parties any other matter that may be included in an order made by a court under Division 4 of Part 7 (Orders for departure from administrative assessment in special circumstances);

the provisions have effect, for the purposes of Part 5 and section 142, as if they were an order made by consent by a court under Division 4 of Part 7.

(3) If the agreement includes non‑periodic payment provisions:

(a) the provisions have effect, for the purposes of this Act, as if they were a statement made by a court under section 125 in an order made under section 124; and

(b) if the provisions or the agreement is registered in a court having jurisdiction under Part VII of the Family Law Act 1975—Division 13A of Part VII, and Parts XIII and XIIIB, of that Act apply in relation to the provisions as if the provisions were an order made by the court under Part VII of that Act.

Note 1: The effect of paragraph (3)(a) is that the Registrar must make any subsequent administrative assessment on the basis of the annual rate of child support as reduced by the amount or percentage specified in the child support agreement (see section 127).

Note 2: This section does not deal with lump sum payment provisions (see paragraph 84(1)(e) of this Act and section 69A of the Registration and Collection Act).

(5) The provisions of the agreement have effect despite any inconsistency with a court order made before the agreement was entered into.

(6) Where any difficulty arises in the application of this section in or in relation to a particular proceeding, the court exercising jurisdiction in the proceeding may, on the application of a party to the proceeding or of its own motion, give such directions, and make such orders, as it considers appropriate to resolve the difficulty.

Division 5—Notice of the decision

96 Notice of decision to be given

(1) If the Registrar accepts or refuses to accept an agreement made in relation to a child, the Registrar must immediately notify each party to the agreement of the decision.

(2) The notice must include, or be accompanied by, a statement that specifically draws the attention of the parties to the agreement to the right:

(a) to object, subject to the Registration and Collection Act, to the decision (the original decision); and

(3) A contravention of subsection (2) in relation to a decision does not affect the validity of the decision.

(4) If a child support agreement includes lump sum payment provisions, the notice must specify:

(a) the amount of the lump sum payment specified in the agreement; and

(b) any annual rate and daily rate of child support that remains payable after taking into account any remaining lump sum payment (within the meaning of the Registration and Collection Act) that will be credited under section 69A of that Act.

Part 6A—Departure from administrative assessment of child support (departure determinations)

Division 1—Preliminary

98A Simplified outline

The following is a simplified outline of this Part:

• The Registrar can make a determination under this Part to depart from the provisions of this Act relating to administrative assessment of child support for a child.

• A liable parent or a carer entitled to child support can apply for such a determination, or the Registrar can make a determination on his or her own initiative.

• The Registrar must not make a determination in respect of a day that is more than 18 months earlier without leave of a court under section 112.

• The grounds for deciding whether to make a determination are the same as a court uses in deciding whether to make an order under Division 4 of Part 7.

• If the Registrar is considering making a determination, the parties can make a child support agreement in relation to child support payable for the child instead of the Registrar making the determination.

• Under section 80 of the Registration and Collection Act, certain persons can object to a decision to make or refuse to make a determination under this Part.

Division 2—Departures initiated by a liable parent or carer

98B Application for determination under Part

(1) If, at any time when an administrative assessment is in force in relation to a child:

(a) the liable parent concerned; or

(b) the carer entitled to child support concerned;

is of the view that, because of special circumstances that exist, the provisions of this Act relating to administrative assessment of child support should be departed from in relation to the child, the liable parent or carer may, by written application, ask the Registrar to make a determination under this Part.

Note 1: For the determinations that the Registrar may make under this Part see section 98S.

Note 2: The Registrar may only make a determination under this Part in respect of a day that is more than 18 months earlier than the day on which the relevant application is made with a court’s leave under section 112 (see subsection 98S(3B)).

(a) if the reason referred to in paragraph (1)(b) was the only reason for the Registrar refusing to accept the application—a person should be assessed in respect of the costs of the child because the person is a parent of the child; and

(b) if the reason referred to in paragraph (1)(b) was one of the reasons for the Registrar refusing to accept the application—the Registrar should reconsider the application under Division 2 of Part 4 because a person who was to be assessed in respect of the costs of the child is a parent of the child.

(a) the Registrar to make a determination under section 98S; or

(b) the court to make an order under section 118.

(2) The court may grant leave for an order to be made under section 118 if the court is satisfied that it would be in the interest of the parties to the proceeding for the court to consider, at the same time as it hears the application under section 111, whether an order should be made under section 118. If the court does so, the applicant is taken to have made an application to the court under section 116 for such an order.

(3) Otherwise, the court may grant leave for the Registrar to make a determination under section 98S.

(3A) To avoid doubt, the court may grant leave for the Registrar to make a determination under section 98S, or for the court to make an order under section 118, irrespective of what the applicant applied for under section 111.

Matters to be considered

(4) In considering whether to grant leave under subsection (1), the court must have regard to:

(a) any responsibility, and reason, for the delay in:

(i) making an application under section 98B or 116; or

(ii) making a determination under section 98S;

as the case requires; and

(b) the hardship to the applicant (other than the Registrar) if leave is not granted; and

Orders granting leave to specify period

(6) An order granting leave under this section must specify the period in respect of which the Registrar may make a determination or the court may make an order.

(7) The period specified under subsection (6):

(a) must not include a day in a child support period if the day is more than 7 years earlier than the day on which the application under section 111 was made; and

(b) is not limited by the terms of that application.

No requirement to make determination or order

(8) The granting of leave under subsection (1) does not imply that:

(a) the Registrar is required to make a determination under section 98S; or

(b) the court is required to make an order under section 118.

113 Implementation of decisions

When a decision of a court under this Division is made, the Registrar must immediately take such action (if any) as is necessary to give effect to the decision.

113A Pending application not to affect assessment

Subject to section 111C of the Registration and Collection Act (stay orders), the fact that a proceeding is pending under this Division in relation to a person does not, in the meantime, interfere with, or affect, any administrative assessment made in relation to the person, and any such assessment may be registered under the Registration and Collection Act, and amounts of child support and other amounts recovered in relation to the assessment, as if no proceeding were pending.

Division 4—Orders for departure from administrative assessment in special circumstances (departure orders)

The following is a simplified outline of this Division:

• Certain courts can make an order under this Division to depart from the provisions of this Act relating to administrative assessment of child support for a child.

• A person can apply for such an order in certain limited circumstances. (If a person cannot apply for an order under this Division, the person might instead be able to apply for a determination by the Registrar under Part 6A.)

• A court can also make such an order without an application in some circumstances (such as after setting aside a child support agreement).

• A court must not make an order in respect of a day in a child support period that is more than 18 months earlier without leave of the court under section 112.

114 Additional particular objects of Division

Additional particular objects of this Division include ensuring:

(a) that children have their proper needs met from reasonable and adequate shares in the income, earning capacity, property and financial resources of both of their parents; and

(b) that parents share equitably in the support of their children.

116 Application for order under Division

(1) A liable parent or a carer entitled to child support may, in respect of an administrative assessment of child support for a child, apply to a court having jurisdiction under this Act for an order under this Division in relation to the child in the special circumstances of the case if:

(b) both of the following apply:

(i) the liable parent or carer entitled to child support is a party to an application pending in a court having jurisdiction under this Act;

(ii) the court is satisfied that it would be in the interest of the liable parent and the carer entitled to child support for the court to consider whether an order should be made under this Division in relation to the child in the special circumstances of the case; or

(c) in the case of a liable parent—the administrative assessment of child support payable by the liable parent for the child is made under subsection 66(1).

Note 1: For the orders that a court may make under this Division see section 118.

Note 2: With a court’s leave, a court may make an order under this Division in respect of a day that is more than 18 months earlier than the day on which the relevant application was made (see subsection 118(2B)). A person is taken to have applied under this section if leave is granted.

Note 3: A court may make an order under this Division if the court sets aside a child support agreement under section 136.

(2) An application may be made by the carer entitled to child support, or the liable parent, in relation to the child.

117 Matters as to which court must be satisfied before making order

Court may make departure order

(1) Where:

(a) application is made to a court having jurisdiction under this Act for an order under this Division in relation to a child in the special circumstances of the case; and

(b) the court is satisfied:

(i) that one or more of the grounds for departure mentioned in subsection (2) exists or exist; and

(ii) that it would be:

(A) just and equitable as regards the child, the carer entitled to child support and the liable parent; and

(B) otherwise proper;

to make a particular order under this Division;

the court may make the order.

Grounds for departure order

(2) For the purposes of subparagraph (1)(b)(i), the grounds for departure are as follows:

(a) that, in the special circumstances of the case, the capacity of either parent to provide financial support for the child is significantly reduced because of:

(i) the duty of the parent to maintain any other child or another person; or

(ii) special needs of any other child or another person that the parent has a duty to maintain; or

(iii) commitments of the parent necessary to enable the parent to support:

(A) himself or herself; or

(B) any other child or another person that the parent has a duty to maintain; or

(iv) high costs involved in enabling a parent to spend time with, or communicate with, any other child or another person that the parent has a duty to maintain;

(aa) that, in the special circumstances of the case, the capacity of either parent to provide financial support for the child is significantly reduced because of the responsibility of the parent to maintain a resident child of the parent (see subsection (10));

(b) that, in the special circumstances of the case, the costs of maintaining the child are significantly affected:

(i) because of high costs involved in enabling a parent to spend time with, or communicate with, the child; or

(ia) because of special needs of the child; or

(ib) because of high child care costs in relation to the child; or

(ii) because the child is being cared for, educated or trained in the manner that was expected by his or her parents;

(c) that, in the special circumstances of the case, application in relation to the child of the provisions of this Act relating to administrative assessment of child support would result in an unjust and inequitable determination of the level of financial support to be provided by the liable parent for the child:

(i) because of the income, earning capacity, property and financial resources of the child; or

(ia) because of the income, property and financial resources of either parent; or

(ib) because of the earning capacity of either parent; or

(ii) because of any payments, and any transfer or settlement of property, made or to be made (whether under this Act, the Family Law Act 1975 or otherwise) by the liable parent to the child, to the carer entitled to child support or to any other person for the benefit of the child.

High costs involved in enabling parent to care for a child

(2B) A parent’s costs involved in enabling the parent to care for a child can only be high for the purposes of subparagraph (2)(a)(iv) or (2)(b)(i) if the costs that have been or will be incurred, during a child support period, total more than 5% of the amount worked out by:

(a) dividing the parent’s adjusted taxable income for the period by 365; and

(b) multiplying the quotient by the number of days in the period.

(2C) If a parent has at least regular care of a child, then the only costs that can be taken into account for the purposes of subsection (2B) are costs related to travel to enable the parent to spend time with, or communicate with, the child.

High child care costs

(3A) The ground for departure mentioned in subparagraph (2)(b)(ib) is taken not to exist unless:

(a) the costs are incurred by a parent or a non‑parent carer; and

(b) the child is younger than 12 at the start of the child support period.

(3B) Child care costs for a parent can only be high for the purposes of subparagraph (2)(b)(ib) if, during a child support period, they total more than 5% of the amount worked out by:

(a) dividing the parent’s adjusted taxable income for the period by 365; and

(b) multiplying the quotient by the number of days in the period.

(3C) Child care costs for a non‑parent carer can only be high for the purposes of subparagraph (2)(b)(ib) if, during a child support period, they total at least 25% of the costs of the child for that period.

Matters to consider for purposes of subparagraph (1)(b)(ii)

(4) In determining whether it would be just and equitable as regards the child, the carer entitled to child support and the liable parent to make a particular order under this Division, the court must have regard to:

(a) the nature of the duty of a parent to maintain a child (as stated in section 3); and

(b) the proper needs of the child; and

(d) the income, property and financial resources of each parent who is a party to the proceeding; and

(da) the earning capacity of each parent who is a party to the proceeding; and

(e) the commitments of each parent who is a party to the proceeding that are necessary to enable the parent to support:

(i) himself or herself; or

(ii) any other child or another person that the person has a duty to maintain; and

(f) the direct and indirect costs incurred by the carer entitled to child support in providing care for the child; and

(g) any hardship that would be caused:

(i) to:

(A) the child; or

(B) the carer entitled to child support;

by the making of, or the refusal to make, the order; and

(ii) to:

(A) the liable parent; or

(B) any other child or another person that the liable parent has a duty to support;

by the making of, or the refusal to make, the order; and

(iii) to any resident child of the parent (see subsection (10)) by the making of, or the refusal to make, the order.

(5) In determining whether it would be otherwise proper to make a particular order under this Division, the court must have regard to:

(a) the nature of the duty of a parent to maintain a child (as stated in section 3) and, in particular, the fact that it is the parents of a child themselves who have the primary duty to maintain the child; and

(b) the effect that the making of the order would have on:

(i) any entitlement of the child, or the carer entitled to child support, to an income tested pension, allowance or benefit; or

(ii) the rate of any income tested pension, allowance or benefit payable to the child or the carer entitled to child support.

Proper needs of the child

(6) In having regard to the proper needs of the child, the court must have regard to:

Income, earning capacity, property and financial resources

(7) In having regard to the income, earning capacity, property and financial resources of the child, the court must:

(b) disregard:

(i) the income, earning capacity, property and financial resources of any person who does not have a duty to maintain the child, or who has such a duty but is not a party to the proceeding, unless, in the special circumstances of the case, the court considers that it is appropriate to have regard to them; and

(ii) any entitlement of the child or the carer entitled to child support to an income tested pension, allowance or benefit.

(7A) In having regard to the income, property and financial resources of a parent of the child, the court must:

(a) have regard to the capacity of the parent to derive income, including any assets of, under the control of, or held for the benefit of, the parent that do not produce, but are capable of producing, income; and

(b) disregard:

(ii) any entitlement of the child or the carer entitled to child support to an income tested pension, allowance or benefit.

(7B) In having regard to the earning capacity of a parent of the child, the court may determine that the parent’s earning capacity is greater than is reflected in his or her income for the purposes of this Act only if the court is satisfied that:

(a) one or more of the following applies:

(i) the parent does not work despite ample opportunity to do so;

(ii) the parent has reduced the number of hours per week of his or her employment or other work below the normal number of hours per week that constitutes full‑time work for the occupation or industry in which the parent is employed or otherwise engaged;

(iii) the parent has changed his or her occupation, industry or working pattern; and

(b) the parent’s decision not to work, to reduce the number of hours, or to change his or her occupation, industry or working pattern, is not justified on the basis of:

(i) the parent’s caring responsibilities; or

(ii) the parent’s state of health; and

(c) the parent has not demonstrated that it was not a major purpose of that decision to affect the administrative assessment of child support in relation to the child.

Direct and indirect costs in providing care

(8) In having regard to the direct and indirect costs incurred by the carer entitled to child support in providing care for the child, the court must have regard to the income and earning capacity foregone by the carer entitled to child support in providing that care.

(9) Subsections (4) to (8) (inclusive) do not limit other matters to which the court may have regard.

(2) When the decision of the court making the order becomes final, the Registrar must immediately take such action as is necessary to give effect to the order in relation to any relevant administrative assessment that has been made (whether by amending the assessment or otherwise).

(3) In subsequently making a relevant administrative assessment, the Registrar must:

(a) work out what would, apart from this Division, be the annual rate of child support payable by the liable parent to the carer entitled to child support; and

(1) If an order under section 123A or 124 is in force in relation to a child (whether or not all things ordered to be done by the order have been done):

(a) the court that made the order; or

(b) another court having jurisdiction under this Act in which the order has been registered;

may under this section, by order:

(a) just and equitable as regards the child, the carer entitled to child support and the liable parent concerned; and

(b) otherwise proper;

to make the order.

(3) The court must not, by order under subsection (1), vary an order unless it is also satisfied:

(a) that making the variation is justified because of a change in the circumstances of the child, the carer entitled to child support or a liable parent concerned since the order was made or last varied; or
