What Exactly Is a TFN?
A TFN in Australia is a unique 9-digit number issued by the Australian Taxation Office (ATO) to identify individuals and businesses for tax purposes. It serves as your personal reference number in all dealings with the ATO. Whether you’re working, studying, or running a business, the TFN is crucial to ensure you're taxed correctly and that your financial records remain in order. This number is used when filing tax returns, opening bank accounts, and applying for government benefits.
Why Is a TFN Important in Australia?
The importance of a TFN lies in its role as a gateway to participating in Australia’s financial and tax systems. Without it, you’ll likely be taxed at the highest marginal rate, which can significantly reduce your take-home income. You’ll also struggle to open a bank account or access essential services. That’s why having a TFN is one of the first steps for anyone settling or working in Australia. If you're an international student, you can apply for a TFN as a student here.
