How to Apply for a Tax File Number (TFN) in Australia

If you plan to work, study, or bank in Australia, obtaining a Tax File Number (TFN) is imperative. A TFN is a unique identifier issued by the Australian Taxation Office (ATO) that ensures you are taxed correctly, can lodge tax returns, and access government services without unnecessary deductions.

What Is a TFN and Why You Need One

A Tax File Number in Australia is your personal reference within the tax system. Although not legally mandatory, you will be taxed at the highest marginal rate if you lack one. With a TFN, you can:

• Start employment and receive accurate pay
• Open bank accounts and invest
• Lodge your annual tax return online
• Apply for government benefits
• Contribute to and manage superannuation

Who Needs a TFN?

You should apply for a TFN if you are:

• An Australian citizen or permanent resident
• A temporary resident on a working holiday visa or student visa
• A foreign passport holder working in Australia
• A contractor, tradie or FIFO worker providing services under an ABN
• A business or company director

• A valid passport or Australian birth certificate
• Visa grant notice (for non-residents)
• Proof of Australian residential address

Processing Time

Most applicants receive their TFN by mail within 10–28 days of successful submission. Applications requiring further verification may take up to 50 days. Use the Australia Tax Office contact number (13 28 61) for any inquiries.

Is a TFN Secure and Private?

Your TFN number in Australia is strictly confidential. Only share it with:

• Employers (to apply correct tax rates)
• Banks and financial institutions
• The ATO and your superannuation fund

Avoid disclosing your TFN on public platforms or to unauthorized third parties.

Can You Start Work Without a TFN?

Yes. Inform your employer that you have applied and provide proof of submission. You must supply your TFN within 28 days to prevent higher withholding taxes.

Quick Recap

Additional Tips for New Arrivals

Furthermore, if you are planning to work under an ABN in entry level FIFO jobs, ensure you have both your TFN and ABN in place. This dual setup enables smooth invoicing and compliance with the Australian business registration requirements.

In addition, store a digital copy of your TFN correspondence in a secure folder, and update your address via your myGov account if you relocate.
