Tax file number - application or enquiry for individuals

How to apply

If you are an Australian citizen 16 years old or older and able to attend an interview at one of the participating Australia Post retail outlets, you can apply for a TFN on the web.

Otherwise, you will need to complete a paper Tax file number - application or enquiry for individuals (NAT 1432) form. You can get a copy of this form:

• from online ordering
• by phoning 1300 720 092 24 hours a day, 7 days a week
• from one of our shopfronts or selected newsagents, or
• by asking for one from Centrelink or the Department of Veterans' Affairs if you are applying for a government benefit or pension.

The form must be accompanied by original documents which prove your identity.

Your TFN will not be processed without the necessary documents. A full list of acceptable documents is provided in the instructions to the form.

If you cannot find your TFN or are not sure you have a TFN, check all your correspondence from us, contact your registered tax agent or phone us on 13 28 61 between 8.00am and 6.00pm, Monday to Friday.

A sample of the Tax file number - application or enquiry for individuals (NAT 1432, PDF 176KB) is available for your reference. Do not print and submit this form as it cannot be processed by our systems. You must order and complete the paper copy provided by us.
