Stolen TFNs & Delayed Refunds: The 2025 Guide to Tax Identity Fraud

Published: June 2025

When it comes to tax time, there’s one little number you do NOT want slipping into the wrong hands… your Tax File Number (TFN). That unique 9-digit code is like your financial fingerprint. And if it ends up in the hands of a scammer, it can spell chaos, headaches, and a serious delay to your tax refund.

Let’s break it down the Derek way — plain English, no fluff, and loads of smart tips to keep your refund timeline smooth and scam-free.

What is Your TFN and Why Should You Care?

Your TFN is your secret code to all things tax. The ATO uses it to match your income, prefill your return, and process your refund. It’s private, it’s personal, and it’s not something you want floating around the dark corners of the internet.

If someone steals your TFN, they might:

• Lodge a fake tax return in your name

• Access your superannuation

• Apply for credit in your name

• Delay your actual tax refund while the ATO untangles the mess

Scammers are getting slicker every year. They’re spoofing ATO numbers, faking employer records, and even sending realistic-looking emails. In short: identity theft is booming, and TFNs are prime targets.

How Would I Know If My TFN Was Stolen?

Here are the classic red flags:

• You get a tax debt notice… but you haven’t lodged yet.

• Your tax return is held up longer than usual.

• You receive an unexpected ATO communication about a return or refund.

• You can’t link your myGov account — someone may have already done it.

If anything smells off, call the ATO’s Identity Theft Hotline:

Derek's Top Tips: How to Protect Your TFN in 2025

Like locking your front door or hiding the good biscuits — some things just make sense. Protecting your TFN is one of them:

✅ Only give it out when required (tax agent, employer, bank).
❌ Never post it, email it, or text it.
✅ Destroy any physical documents that show your TFN before tossing them.
✅ Keep your myGov account locked down with two-factor authentication.
✅ Report suspicious emails, texts, or phone calls. The ATO will never demand payment via iTunes, gift cards, or Bitcoin. (Yes, that’s still happening…)

If Your TFN is Stolen — What Happens Next?

If the ATO thinks someone’s lodged a fake return using your TFN, they’ll:

• Put a hold on your return

• Launch an investigation

• Possibly request more ID from you

Translation? Delays, delays, and more delays.

The faster you report the issue, the faster things can be resolved. So if in doubt, act now. Your refund depends on it.
