Are you having trouble finding your Tax File Number? (TFN)
If you already have a TFN and don’t remember the number, you can find it online in ATO online services via your myGov account.
If you don’t have a myGov account, you can usually find your TFN on:
- your income tax notice of assessment, if you have lodged a Tax Return
- letters you have received from the ATO, such as a statement of account
- a payment summary or income statement (provided by your employer)
- your superannuation account statement.
If you still having trouble finding your Tax File Number after checking these options, you can phone the ATO on 13 28 61
