Quick TFN Tips (2026)

• Where to apply: Only on the ATO website
• Cost: TFN applications are 100% free
• Avoid scams: Never use paid websites — even if they “look official”
• Required documents: Passport, visa grant, Aussie address
• Who needs a TFN? Workers, students, temp visa holders, ABN holders
• How long it takes: 1–4 weeks to arrive by mail

What Is a TFN and Why You Need One

What is a Tax File Number (TFN)?

A Tax File Number (TFN) is a unique 9-digit number the Australian government gives you for life. You need it to work, pay tax, open a bank account, or claim super. Think of it like your Aussie tax identity — you only get one, and you keep it forever.

Who needs a TFN in Australia?

If you're working, studying, or staying in Australia on a visa, you probably need a TFN. Here's who should apply:

• New international students Pls follow this blog to find out the process.
• Working holiday visa holders (subclass 417 or 462)
• Anyone with an ABN (freelancers, side hustlers)
• Migrants on temporary or permanent visas
• Citizens and residents getting their first job

When do you need to provide your TFN?

You’ll be asked for your TFN in these common situations:

• Your employer (when starting a job)
• ATO (Australian Tax Office) when filing a return
• Banks (to avoid paying more tax on your interest)
• Super funds (so your retirement savings are taxed correctly)

If you don’t provide it, you could be taxed at the highest rate (45%) on your income or interest. Ouch.

Is Applying for a TFN Free? (Avoid Paid “Helpers”)

TFN Application Cost in Australia

Yes — applying for a TFN is 100% free if you do it through the official ATO website. You do not need to pay anything, even if you're a student, working holiday visa holder, or new migrant.

If a website is asking you to pay for a TFN, stop immediately — it's either a private business pretending to help or a scam.

Bottom line: If you're being charged anything to apply for a TFN, you're not on the ATO website.

Why Third‑Party TFN Websites Charge Fees

Some private websites act like “TFN assistance services” and charge you $30 to $100+ just to fill out the same free form, you could do yourself in 10 minutes.

Here’s how they try to justify their fees:

• “Express TFN application”
• “Faster processing” (spoiler: they can’t)
• “Expert help for migrants and students”

But none of them are official. They simply collect your details, enter them into the ATO system, and keep the fee. You don’t get your TFN faster — and you risk giving your personal ID to someone you can’t trust.

How TFN Scam Websites Trick You (Real Examples + Red Flags)

These sites often:

• Use “.com” or “.org” domains (never “.gov.au”)
• Look like the ATO with Aussie flags and logos
• Use fake urgency: “Last date to apply!” or “Only 3 TFNs left”
• Say they’re “partners of ATO” (which the ATO never does)

Real example from a comment on our page:

“I applied through tfnexpress.com.au and paid $89. Never got anything. Now I can’t reach them.”

– International student, Melbourne

Safe Rule: Only Use Official Government Channels

There’s only one place you should apply: https://www.ato.gov.au/Individuals/Tax-file-number/

This page links you to the myGov platform, where you can:

• Submit your TFN application
• Track your status
• Update your details securely

Never apply for a TFN through a .com, .net, or .org site — no matter how “official” it looks.

Real Tip from Vicky

“Over the last two years, I’ve seen dozens of students and migrants lose money to fake TFN websites. One paid $65 and didn’t even realise until we showed them the official ATO link. Don’t be fooled by good design — always double-check the URL.”

TFN Scam Warning: Real Stories and Red Flags

Unfortunately, TFN scams are becoming more common, especially targeting new migrants, students, and working holiday makers. These fake sites often look official, but they exist solely to take your money — or worse, steal your identity.

Let’s break down what these scams look like, what real users have experienced, and how to stay safe.

Real Scam Examples from Migrants and Students

Case 1: Paid $89 for Nothing

“I searched ‘apply for TFN’ on Google and clicked the first link. It looked legit — had a flag and Aussie logo. Paid $89. After two weeks, nothing arrived. When I emailed them, no reply.”

– Temporary resident, Sydney

Case 2: Gave Passport Details to a Scam Site

“I didn’t know it should be free. The site asked for my passport number, visa, and even a scanned signature. It was only after talking to a friend I realised it wasn’t the ATO.”

– International student, Brisbane

Case 3: Lost TFN + ABN Fees to the Same Site

“They offered a TFN and ABN combo for $149. I applied, paid, and never got anything. They stopped replying the moment I asked for a refund.”

– Freelance worker on 408 visa, Melbourne

These are not isolated. We’ve had dozens of messages and comments from people caught in similar traps

How to Report TFN Scams and Protect Your Identity

To take action:

• Report scams via Scamwatch
• Report identity theft via IDCARE
• Let your bank know if you used a credit card — you may be able to reverse the charge
• Warn others — leave a review, post in migrant groups, or message pages like ours to help stop the spread

We regularly flag these sites publicly and have received over 370 comments and reactions on our TFN scam alert posts — this is a real issue affecting real people.

How to Protect Your TFN After You Get It

Once you receive your TFN, it’s yours for life — but that also means you need to protect it like a password. Your TFN links directly to your identity, income, super, and tax records. If someone gets hold of it, they could file fake tax returns, open accounts in your name, or even commit fraud.

Here’s how to keep it safe.

Who You Should Share Your TFN With

You’re only expected to give your TFN to trusted and legally authorised organisations.

This includes:

• The Australian Taxation Office (ATO)
• Your employer (after you accept a job offer)
• Banks and financial institutions (for interest income)
• Superannuation funds (to link your TFN and avoid extra tax)
• Your registered tax agent or accountant

These organisations are bound by law to protect your TFN and use it only for tax-related purposes.

Who Should Never Ask for Your TFN

If someone outside the list above asks for your TFN, don’t give it.

Red flags include:

• Landlords or real estate agents
• Mobile phone providers
• Online services or unknown apps
• Recruitment agencies or job sites (before you're hired)
• Education agents or overseas consultants

They may ask for it out of habit or misunderstanding, but no private company can legally demand it unless they’re regulated under tax law.

What to Do if Your TFN Is Stolen or Leaked

If you’ve accidentally shared your TFN with someone suspicious — or worse, on a scam website — take action immediately.

Step-by-step:

1. Call the ATO on 13 28 61 and explain what happened
2. Request a TFN misuse investigation
3. Monitor your myGov account for unusual activity
4. Contact IDCARE — they specialise in identity theft
5. Avoid sharing your TFN again unless necessary

The ATO rarely cancels TFNs, but they can flag your file and investigate any suspicious use.

Real Reminder from Vicky

“A lot of people treat their TFN like a casual ID — but once it’s out there, you can’t take it back. I’ve worked with students who shared their TFN on forms without knowing where it went. Months later, they found someone filed tax returns in their name.”

TFN FAQs

How long does it take to get a TFN?

Once you apply through the ATO, your TFN typically arrives by post within 10 to 28 days. It may take longer if you entered incorrect details or applied during peak times. The ATO does not send your TFN by email or SMS.

Can I work while waiting for my TFN?

Yes, you can start working after applying for a TFN. Let your employer know you've applied, and provide the number as soon as it arrives. You may be taxed at a higher rate until your TFN is recorded, but this can be adjusted later.

Can I apply for a TFN from overseas?

No, you must be physically in Australia on a valid visa before you can apply for a TFN. The application system checks your visa status with immigration. You also need an Australian postal address to receive your TFN letter.

Do I need a TFN to get an ABN?

Yes, having a TFN is recommended when applying for an ABN. It helps the ATO verify your identity and tax status. If you apply for an ABN without a TFN, your application may be delayed or rejected.

Can I change my TFN?

No, your TFN is for life — it does not change, even if your visa, name, or job does. If your TFN is lost or compromised, you can ask the ATO to investigate for misuse, but they will not usually issue a new number.
