  • How we can help you

    Report the loss or theft of your TFN without delay.

    • If you have lost your TFN and do not suspect misuse, phone us on 13 28 61 between 8.00am and 6.00pm, Monday to Friday.
    • If your TFN has been stolen or misused, phone us on 1800 467 033 between 8.00am and 6.00pm, Monday to Friday.
    • If you do not speak English well and want to talk to a tax officer, phone the Translating and Interpreting Service on 13 14 50 for help with your call.

    If you think that your information might be at risk, and you might become a victim of identity crime, we can also help by monitoring the use of your TFN.


    • Using another person's TFN, misusing yours, or allowing it to be used by others, and 'buying' or 'selling' a TFN, are all serious crimes which can result in heavy fines or jail.
    • If you have legitimate access to the identity details of other people, including their TFN, you must keep that information secure
