  • Tax file number – application or enquiry for individuals

    How to apply

    If you're an Australian resident for tax purposes, and can attend an interview at a participating Australia Post retail outlet, you can apply for a TFN on the web. Use the Australia Post office locatorExternal Link to find out where you can present your identity documents.

    Otherwise, you'll need to complete a paper form Tax file number – application or enquiry for individuals (NAT 1432). You can get a copy of this form by:

    • ordering online
    • phoning 1300 720 092 (24 hours a day, 7 days a week)
    • asking for one from Centrelink or the Department of Veterans’ Affairs if you're applying for a government benefit or pension.

    The form must be accompanied by documents which prove your identity – your TFN won't be processed without these. Send us certified copies of documents – don't send original documents. Certified copies of documents you mail to us may not be returned to you.

    A full list of acceptable documents is provided in the instructions to the form.

    If you can't find your TFN or aren't sure you have a TFN, check all your correspondence from us, contact your registered tax agent, or phone us on 13 28 61 between 8.00am and 6.00pm, Monday to Friday.

    Next step:

    Note: Don't print and submit this online sample form – you must instead complete the paper copy we provide when you order the form from us.
