What is a TFN?
A Tax File Number is your personal reference number in Australia's tax system. Without one, tax is withheld at the highest rate.
How to apply
Apply free online through the Australian Taxation Office after you arrive. You'll need your passport and an Australian address.
Keep it private
Only share your TFN with the ATO, your employer (after starting work), your bank, and your super fund.
