How do I find my TFN?
Before you apply for a TFN, check to make sure you don’t have one already. If you do have a TFN, you can find it from
- your income tax notice of assessment
- correspondence from the ATO
- a payment summary from your employer
- your superannuation member statement
- your registered tax agent
If you still can’t find your TFN, you can phone the ATO at 13 28 61.
