Whether you’re starting your first job, launching your dream business, or moving to Australia, you’ll quickly come across a small but mighty term — the Tax File Number (TFN).
A TFN is a unique number that plays a huge role in your financial life in Australia. It’s kind of like your tax fingerprint — it’s how the government identifies you for all things tax-related. But don’t worry, even if taxes sound scary, we’re here to break it down in plain English. You’ll walk away knowing exactly what it is, why it matters, and how to apply for a TFN step-by-step.
Why is a Tax File Number (TFN) Important?
Imagine this: Mia just landed her first job at a local cafe in Sydney. She was excited — until she noticed a big chunk missing from her first paycheck. Why? She didn’t have a TFN yet.
Without a TFN, your employer must withhold the highest tax rate (which can go up to 47%). That’s a lot of your hard-earned cash gone before you even get to enjoy it.
Having a Tax File Number means:
-
You pay less tax.
-
You can lodge your tax return.
-
You get access to government benefits, like HECS-HELP for students.
-
You can open a bank account.
-
You can register a business or ABN (if you’re self-employed or a sole trader).
