What Is a TFN and How Do I Get One? (2026)
How do I apply for a TFN?
If you're in Australia on a visa with work rights, apply online through the ATO's registration for foreign passport holders — you only need your passport and an Australian address. The system checks your visa automatically, and the TFN letter arrives by mail within 28 days. Applying is always free.
Can I work while I wait for my TFN?
Yes. You can start a job immediately and have 28 days to give your employer the TFN. After 28 days without it, they must withhold tax at the highest rate — so apply on day one in Australia.
What is the difference between a TFN and an ABN?
A TFN makes you an employee: your employer withholds tax and pays superannuation on top of your wage. An ABN makes you a contractor responsible for your own tax and super. If a cleaning, delivery or labouring job tells you to "get an ABN" for what is really employee work, that is usually a red flag to dodge your entitlements.
Do I need a new TFN if I change visas?
No — your TFN is yours for life. It stays the same across visa changes, employers, and even if you leave Australia and come back years later.
How do I keep my TFN safe?
Only give it to your employer (after you start), the ATO, your super fund, and your bank. Never put it in a job application, and ignore anyone who calls "from the ATO" demanding your TFN or payment — that is always a scam.
