What is a TFN and how can I get one to work in Australia?

How to apply for a TFN in Australia: complete step-by-step guide

If you’re going to work in Australia, you need a TFN (Tax File Number). Here we explain what it is, who needs it, and how to apply correctly step by step.

1️⃣ What is a TFN?

A TFN (Tax File Number) is your personal tax number in Australia. It’s required to work legally and so your employer can withhold the correct amount of tax from your pay.

If you work without a TFN, your employer may withhold tax at the highest rate.

2️⃣ Who needs a TFN?

  • Work and Holiday Visa (WHV)
  • International students
  • Temporary residents
  • Permanent residents
  • Anyone who will work legally

Even if you only work for a few weeks, you still need a TFN.

3️⃣ How to apply for a TFN step by step

The process is free and done online.

1) Be physically in Australia

You must be in Australia with a valid visa that allows you to work.

2) Have your passport and visa details ready

You’ll need your passport number, visa details, and your date of entry to Australia.

3) Complete the online form

Access the TFN application form and select the option for people with a temporary or permanent visa.

4) Enter your personal details

Full name, date of birth, and nationality exactly as shown on your passport.

5) Enter an Australian postal address

Your TFN will arrive by mail to that address, so it must be correct and accessible.

6) Add contact information

Email and an Australian phone number if you have one.

7) Carefully review your details

Mistakes in your name or visa details can delay the process.

8) Submit your application

Once submitted, you’ll receive a reference number.

9) Wait for the letter

The TFN usually takes between 7 and 28 days to arrive by post.

10) Provide your TFN to your employer

You have 28 days to give it to your employer from the date you start working.

Even though you can start working without a TFN, if you don’t provide it in time your employer may apply the highest withholding rate.

4️⃣ Common mistakes when applying for a TFN

  • Misspelling your name (it must match your passport)
  • Entering an incorrect address
  • Mistakes in your visa details
  • Not saving your reference number

5️⃣ TFN and your Tax Return

A TFN is essential to lodge your annual Tax Return. Without it, you won’t be able to claim a refund or manage your tax situation properly.

Many people end up paying more tax than necessary simply because they don’t understand how the system works.
