No fluff just solution...

The rising tide of tax identity fraud in the UK costs taxpayers millions each year. Fraudsters are becoming increasingly sophisticated in their methods to steal personal information.


HMRC reported over 1,000,000 phishing attempts in 2022 alone. This staggering figure demonstrates just how widespread the problem has become in recent years.


Understanding prevention measures is essential for protecting your identity and tax affairs. These criminals are constantly evolving their tactics to bypass security measures.


Pie tax, the UK's first personal tax app, offers real-time alerts when suspicious activity occurs on your tax account. Or if you're just here to get to grips with it all, let's break it down!

What is tax identity fraud and why should you care?

Tax identity fraud happens when criminals use your personal details to submit fake tax returns. They might redirect your tax refund to their bank account or create bogus self-employment records.


Common methods include phishing emails pretending to be from HMRC and data breaches. Some fraudsters even attempt direct impersonation over the phone to extract your information.


You might notice something's wrong when you receive letters about tax submissions you never made. Or worse, when HMRC contacts you about unpaid taxes for income you never earned.


UK taxpayers lose an estimated £4.5 billion annually to various forms of tax fraud. That's money that could fund vital public services instead of lining criminals' pockets.

Simple steps to prevent tax identity theft

Always keep your National Insurance number, UTR, and Government Gateway details private. These identifiers should be treated with the same caution as your bank details.


Create strong, unique passwords for your tax accounts. A password manager can help you maintain different secure passwords for various services without needing to remember them all.


Enable two-factor authentication on your Government Gateway account. This extra security step makes it significantly harder for fraudsters to access your account, even with your password.


Be extremely cautious about sharing personal details on social media. Information like your date of birth or address history can help criminals piece together enough data to steal your identity.


Check your tax account regularly for any unexpected changes or submissions. I once spotted an unfamiliar address change on my account that alerted me to an attempted fraud before any damage was done.

Spotting fake HMRC communications

HMRC will never notify you about tax refunds via email or text message. If you receive a message promising money back, treat it with extreme suspicion.


Official government emails always end with @hmrc.gov.uk but be vigilant. Scammers can make emails appear to come from legitimate addresses through clever formatting tricks.


Genuine HMRC messages never request personal financial information via email or text. They already have the information they need about your tax affairs.


If you're unsure about any communication claiming to be from HMRC, don't click any links. Instead, log into your tax account directly through the official gov.uk website.


HMRC has a dedicated phishing reporting service for suspicious communications. Forward questionable emails to and texts to 60599.

What to do if you think you've been targeted

Act quickly if you suspect your tax identity has been compromised. Contact HMRC's dedicated fraud hotline immediately to report your concerns.


Report the incident to Action Fraud and obtain a crime reference number. This creates an official record of the fraud attempt for future reference.


Check your credit report for any unusual activity or applications. Tax fraudsters might also attempt to take out loans or credit cards in your name as part of a wider identity theft.


Keep detailed records of all communications regarding the fraud. Note down who you spoke to, when the conversation took place, and what was said or agreed.


Tell your bank and other financial institutions to be on alert for suspicious activity. They can implement additional security measures on your accounts to prevent further fraud.


Final Thoughts

Tax identity fraud isn't going away, but taking preventative steps significantly reduces your risk. Simple measures can make you a much harder target for opportunistic criminals.


Regular monitoring, secure passwords, and healthy scepticism about unexpected communications are your best defences. These habits will protect not just your tax affairs but your wider financial security.


Remember that HMRC already has most of the information they need about you. If they're suddenly asking for extensive personal details, that should immediately raise concerns.


Staying vigilant doesn't mean becoming paranoid. It simply means developing good security habits that will serve you well in all aspects of your digital life.
