Whether you’re new to Australia, just landed your first job, or starting your own business, getting a Tax File Number (TFN) is one of the first and most important things you’ll need to do. But don’t worry — it’s easier than it sounds. This guide breaks it down step-by-step using plain English and real-life tips to help you through the process.
What is a Tax File Number (TFN) and Why Do You Need It?
A Tax File Number is a unique, 9-digit number issued by the Australian Taxation Office (ATO). It’s how the government identifies you for tax and superannuation purposes.
Without a TFN, you might:
-
Pay more tax than you need to (up to 47%!)
-
Have trouble starting a job
-
Delay receiving your superannuation
-
Miss out on government benefits
Quick story:
When Lisa, a uni student from Melbourne, started her part-time café job without a TFN, her employer had to withhold tax at the highest rate. Once she finally got her TFN, it was a hassle to fix her tax situation. Learn from Lisa — get your TFN early!

️ Step-by-Step: How to Get a TFN in Australia
Here’s the good news: applying for a TFN is free and you only have to do it once in your lifetime.
1. Choose the Right Application Method
Depending on your situation, there are different ways to apply:
a) If You’re an Australian Resident
You can apply online via the ATO website. You’ll need:
-
A valid Australian passport or other proof of identity (driver’s licence, birth certificate, etc.)
-
An Australian postal address
-
A working myGov account linked to the ATO
b) If You’re a Temporary Visitor or International Student
If you’re on a working holiday visa, student visa, or any other temporary visa, you can also apply online here.
Make sure your visa is active and your details match those in the Department of Home Affairs records.
c) Applying by Paper Form or In-Person
Can’t apply online? You can request a paper form by calling the ATO or visit an Australia Post outlet that offers identity checks.
What Happens After You Apply?
-
You’ll receive your TFN by mail within 10–28 business days
-
The letter will come to the address you provided, so make sure it’s correct!
-
Keep your TFN secure — don’t share it unless it’s required (e.g., with your employer, your bank, or your tax agent)

No worries. You can find it on your payment summary, tax return, myGov account, or call the ATO to retrieve it.
3. Is it okay to give my TFN to my employer or bank?
