We are authorised by the Taxation Administration Act 1953 to request your tax file number (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 there may be a delay processing the Non-lodgment advice form.
We are also authorised by the Income Tax Assessment Act 1936, the Income Tax Assessment Act 1997 and the A New Tax System (Family Assistance) (Administration) Act 1999 to ask for the information on this advice. We need this information to help us administer tax law. If the information is not collected, there could be a delay processing the form.
Where authorised by law, we may give this information to other government departments and agencies, including:
- Department of Education
- Department of Employment
- Services Australia
