  • Keep your TFN and myGov details safe

    Keeping your tax file number (TFN) and other personal identity details secure helps prevent identity crime. Someone only needs some basic details such as your name, date of birth, address, myGov details, or TFN to commit identity fraud.

    Your TFN is how we identify you for tax and super. Each person that applies for a TFN gets their own number, it is yours for life. It is important you don't let anyone else use it – not even friends or family.

    In the wrong hands, your TFN could be used to commit fraud, so keep it safe. Make sure you protect your identity by keeping all your personal details, including your TFN, secure.

    There are only a few people and places that can ask for your TFN:

    • the ATO
    • Centrelink
    • your bank
    • your employer after you start a job
    • your super fund
    • your registered tax agent - you can find a registered tax agent, or check whether a person is a registered tax agent, by visiting the Tax Practitioners boardExternal Link website.

    MyGov is a simple and secure way to access government online services. Your myGov account holds many of your personal identity details, so it is important that you don't share your myGov login details including your password with anyone.

    Your login details should always be kept private and should not be shared with others. This includes your tax agent - they only need your TFN, not your myGov login details to lodge your return.

    Phone the Indigenous helpline on 13 10 30 if your TFN or personal information has been:

    • lost
    • stolen
    • misused.
