A Tax File Number (TFN) is your personal reference number in the tax and superannuation systems.
This unique (usually 9 digit) number is legally required if you are employed in Australia and are above 15 years of age. Your TFN is yours for life, even if you change jobs, name, move interstate of go overseas. TFNs are provided by the Government through the Australian Taxation Office (ATO).
Here we explain how to apply for your TFN as an Australian or Non-Australian citizen.
Why do I need a TFN?
You don’t have to have a TFN, but without one, your employer or financial institution must withhold more tax from the payments they make to you.
Additionally, without a TFN you:
- Can’t apply for government benefits or allowances (JobSeeker)
- Can’t lodge your tax return online
- Can’t apply for an Australian Business Number (ABN)
Australian Citizen
