How to Recognise and Avoid Self Assessment Tax Scams

Published Date: December 12, 2024

( Last Updated: September 26, 2025 )

With the deadline to file Self Assessment Tax Return approaching fast, scammers are growing active and are targeting unsuspecting taxpayers. Fraudsters are using deceptive emails, phone calls and text messages to pose as HMRC and cheat people.

Those fraudulent communications seek to trick you into revealing sensitive information, enabling scammers to steal your money. But there is no reason to worry. There are ways to spot such scams and protect ourselves.

Understanding the Threat

HMRC received over 130,000 reports of tax scams in the year leading to September 2023, with 58,000 of those involving fake tax rebate offers. HMRC expects a surge in such scams this time too as the Self Assessment deadline approaches.

“Fraudsters are skilled impersonators,” warns HMRC. “They mimic government messages to deceive people. Unexpected contact from HMRC should always raise suspicion.”

Common Types of Tax Scams

Scammers use various tactics to exploit taxpayers. Here are some of the most common methods:

  • Fake Tax Rebates - Here, fraudsters claim you are eligible for a tax refund and ask for personal details or banking information to process it. Legitimate services offering tax refunds can make this scam harder to detect.
  • Threatening Messages - Scammers may send messages warning of fines, legal action or even arrest for alleged tax evasion, pressuring you to act immediately.
  • False Tax Claims - Criminals might submit a fake tax refund claim on your behalf, charging a fee for the service. When HMRC later identifies the claim as invalid, you are responsible for repaying the amount while losing the fee paid to the scammers.
  • Phishing Emails - Fraudulent emails mimic HMRC’s branding and official email addresses. These can include links to fake websites or attachments that can steal your financial information.

How to Spot a Scam

No scam is ever perfect and scammers always leave clues. Here are some tips that can help you spot those clues and prevent getting scammed.

  • Be Skeptical of Unexpected Contact - If you receive a text, email or phone call claiming to be from HMRC, don’t respond immediately. Instead, contact HMRC directly through verified channels to confirm the communication.
  • Beware of Suspicious Links and Attachments - HMRC will never ask for personal or financial information through emails or texts. Avoid clicking on links or opening attachments in unsolicited messages.
  • Watch Out for Automated Calls - If you get an automated call claiming to be from HMRC threatening legal action, hang up immediately. Block the number if possible.
  • Verify QR Codes – Although HMRC does include QR codes in some letters, these never direct you to pages asking for sensitive financial or tax details.

How to Report Scams

HMRC actively encourages the reporting of suspicious emails, texts and phone calls. Visit the official government website (GOV.UK) for detailed instructions on how to report such incidents.

Conclusion

Scams are getting smarter, making it important to stay alert. Criminals often pretend to be HMRC, tricking people with fake tax refunds, phishing emails and threatening messages. As the Self Assessment tax deadline nears, these scams will likely jump.

Watch out for warning signs like unexpected messages, suspicious links or automated calls. Report anything suspicious to stay safe. Being informed and careful is the best way to protect yourself and your money.
