  • How to find your TFN

    Your TFN is yours for life, even if you change jobs, move interstate or change your name. If you leave the country and come back to Australia, you still use the same TFN.

    You can find your TFN on:

    • your income tax notice of assessment
    • any correspondence we have sent you
    • a payment summary - for example, from your employer
    • your superannuation member statement.

    If you have a registered tax agent, you can ask them for your TFN.

    If you still can't find your TFN, you can contact us. We will need to know that we are talking to the correct person before we can discuss your tax affairs, so we will ask you for details only you or your authorised representative would know.
