Tax File Number (TFN)

If you want to file the annual tax returns electronically, apply for Australian business number (ABN), or benefit from government services, you must apply for your unique lifelong tax file number (TFN).


TFN remains unchanged even if your name, occupation or country residency is changed.

It is highly advised to secure your TFN since it works as a reference for all your professional and personal affairs such as your tax and super documents.
