It is estimated that more than 95 million records will be obtained, including the records for approximately 1.2 million individuals.


These records will be electronically matched with certain ATO data holdings to identify non-compliance with registration, lodgment, reporting and payment obligations under taxation laws.


This program is called the share transactions data matching program and its purpose is to ensure that taxpayers are correctly meeting their taxation obligations in relation to the share transactions. These obligations include registration, lodgment, reporting and payment responsibilities. Its objectives are to:


§  Identify income tax returns that may not include accurate information relating to the disposal of shares and securities, especially in relation to capital gains tax

§  Improve the taxpayer and tax agent understanding and awareness of their capital gains tax obligations

§  Identify taxpayers that have outstanding returns or not correctly registered for their taxation obligations

§  Develop intelligence and indicators to detect emerging trends and issues

§  Enhance voluntary compliance through initiatives such as pre-populating information into taxation returns

§  Generally ensure compliance with registration, lodgment, correct reporting and payment of taxation and superannuation obligations.


A document describing this program has been prepared in consultation with the Office of the Australian Information Commissioner. A copy of this document is available:
