How to get a Tax File Number (TFN)

A tax file number is your personal reference number issued by the Australian Taxation Office in the tax and superannuation systems. It is an important part of your identity, and it cannot be used by anyone else.

Here are the steps to obtaining your TFN:

1. Choose how to apply

• Apply online through the Australian Taxation Office (ATO) website
• Apply at Australian Post
• Apply by post – using the paper form if you don’t meet the online criteria

2. Prepare your documents

• You’ll need proof of identity (Passport, Australian birth certificate, Driver’s license)
• International students may need visa details, passport details and foreign government identification, etc.

3. Submit your application and wait for your TFN

• Lodge your application and keep your reference number
• The ATO will mail your TFN to you within 28 days after receiving your completed application

Why it’s important to have a TFN:

It’s important to have a TFN because without your TFN, your employer or financial institution provider must withhold more tax payments they make to you. Additionally, you can’t apply for government benefits or allowances (such as Jobseeker) or lodge your tax return online.

Keeping your TFN and personal details safe:

Make sure you protect your identity. Basic information such as your name, date of birth, address, MyGov details or TFN can be enough for someone to commit identity fraud or scams. Only disclose your TFN to people or organisations that require it for legitimate reasons, such as:

• Us – Edith Cowan College
• Your superannuation fund
• Government agencies to claim benefits
• Your employer when you start work and your bank
