If you’re stepping into FIFO (Fly-In Fly-Out) work in Australia, getting your Tax File Number (TFN) is essential. Whether you’re a local or international worker, your TFN helps you get paid correctly and avoid higher tax rates. Let’s break it down.
Why You Need a TFN for FIFO Jobs
A TFN is your personal tax identifier in Australia. Without one, employers may withhold up to 47% of your earnings in tax.
With a TFN, you:
- Get taxed at the correct rate
- Can apply for ABNs or register for superannuation
- Stay compliant with the ATO (Australian Taxation Office)
Who Should Apply?
You need a TFN if you’re:
- Starting FIFO work or any job in Australia
- An international worker on a visa (Working Holiday, Student, etc.)
- Earning money as a sole trader or contractor
What You Need Before Applying
- Valid passport (if you’re not a citizen)
- Australian address (can be temporary)
- Active visa (if you’re applying from overseas)
- Optional: Medicare or Centrelink number
How to Apply for a TFN (Step-by-Step)
If you’re in Australia:
- Go to the ATO TFN application page
- Choose your status (e.g. Australian resident, overseas worker)
- Fill out the online form (takes about 15 minutes)
- Submit and wait for your TFN via post (within 28 days)
If you’re applying from overseas:
- You must have a valid visa that allows work
- Apply via myGovID + ATO or a registered agent
After You Apply
You don’t need to memorise your TFN, just keep it secure
You’ll receive your TFN by mail (make sure your address is correct)
Use your TFN when starting a new job, opening a bank account, or lodging tax
Common Mistakes to Avoid
- Giving your TFN to strangers or via unsecured links
- Using fake agents or paid services — applying is 100% free via the ATO
- Entering incorrect visa or address details
