What if I don't know my TFN?
You can find your TFN on:
- your income tax notice of assessment (NOA)
- correspondence we have sent you
- a payment summary - for example, from your employer
- your superannuation member contribution statement.
If you have a tax agent, you can ask them for your TFN.

- from online ordering
- by phoning 1300 720 092 24 hours a day, 7 days a week
- from one of our shopfronts or selected newsagents
- 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 that 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.
or
Online - 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.
