We are authorised by the Taxation Administration Act 1953 to request your tax file numbers (TFN). We will use your TFN to identify you in our records. It is not an offence not to provide your TFN but if you don't your assessment may be delayed.
We are also authorised by the Income Tax Assessment Act 1936, Income Tax Assessment Act 1997, A New Tax System (Family Assistance) (Administration) Act 1999, Superannuation (Government Co-contributions for Low Income Earners) Act 2003 and the Superannuation (Unclaimed Money and Lost Members) Act 1999 to ask for the other information on the Tax return for individuals. We need this information to help us to administer taxation law. If the information is not collected it could increase the chance of a delay or error in your assessment.
Where authorised by law, we may give this information to other government departments and agencies, including:
- Department of Education
- Department of Employment
- Services Australia
- Department of Social Services
- Department of Veterans' Affairs
- Australian Bureau of Statistics
- Reserve Bank of Australia
We also provide taxpayer information to treaty partners overseas under international tax agreements.
If you have an Australian Business Number, some information on this form may be collected under the A New Tax System (Australian Business Number Act) 1999 and will be used to update your details on the Australian Business Register (ABR). Where authorised by law, selected information may be made publicly available and some may be passed to a wide range of government agencies, including Commonwealth, state and local government agencies.
Our privacy policy contains important information about your privacy, including information about how you can access and seek correction of information we hold about you, how to make a complaint if you think we have breached the Australian Privacy Principles and how we will deal with any privacy complaints.
