Get or find your tax file number

Your TFN is a personal reference number you use for tax and superannuation.

You should have a TFN if you want to get a job, apply for government payments, or get an Australian business number (ABN).

Find your TFN

If you already have a TFN but don't remember the number, you can find it.

Using ATO online services

Other ways
