We are authorised by the Taxation Administration Act 1953 to request tax file numbers (TFNs). 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 this form.

We are also authorised by the Income Tax Assessment Act 1936 and the Taxation Administration Act 1953 to collect the information requested on the form. We need it to provide a TFN to your company, partnership, trust or other organisation. If you do not provide this information, we may not be able to process your application.

We collect some personal information about you because you signed the form. The information collected will enable us to ensure that you are the person with the authority within the entity to complete the form. It will also allow us to contact you if we need further information.

Where authorised by law, we may give this information to other government departments and agencies, including:

  • Department of Human Services
  • Australian Bureau of Statistics
  • Law Enforcement Agencies.

We may check the proof of identity information you supply with the agencies that issued them.

We also provide taxpayer information to treaty partners overseas under international tax agreements.
