HMRC Warns Taxpayers of Scams: Urgent Alert for Self-Assessment Filers

The keyword “HMRC warns taxpayers of scams” has taken center stage in recent months as fraudulent activity surrounding tax rebates and returns reaches alarming levels. With more and more UK citizens filing their Self-Assessment tax returns digitally, scammers are exploiting this digital shift to deceive unsuspecting individuals.
This article will detail the recent warning by HMRC, explain how the scams work, highlight the official position regarding communication methods, and offer actionable tips on how to stay safe. We’ll also cover the closely related topic: “HMRC warns of scams targeting Self-Assessment taxpayers.”
HMRC Warns Taxpayers of Scams: What’s Happening?
Surge in Tax Scam Activity
In the wake of the 2024–2025 Self-Assessment tax return deadline (31 January), many taxpayers reported receiving emails, phone calls, and text messages claiming they were eligible for a tax rebate. These messages may seem convincing and are often designed to look like official communications from HMRC.
What’s particularly dangerous is that these scam messages usually arrive shortly after taxpayers complete their returns, making them appear timely and authentic.
Self-Assessment Taxpayers Are Prime Targets
HMRC officials have noted a sharp increase in phishing scams that directly target Self-Assessment filers. Fraudsters understand that a large number of people may be expecting a refund, and they exploit this expectation to trick victims into handing over sensitive personal and financial information.
How These Scams Work
Typical Scam Formats
The most common formats used by scammers include:
1. Text Messages (SMS)
You may receive a message saying, “You’re eligible for a tax refund. Click here to claim.” These messages often include shortened URLs to obscure their true destination.
2. Emails
Scam emails often carry subject lines like “Important: Your Tax Refund is Ready” or “Final Notice from HMRC.” They may carry official-looking logos and use technical-sounding language to mislead you.
3. Phone Calls
Some victims report receiving threatening phone calls, stating that they owe unpaid tax and will face legal action if they do not comply. Others claim to offer help in claiming a tax rebate.
HMRC’s Official Statement and Guidelines
No Refunds Offered by Text or Email
HMRC has emphasized that they never send notifications of tax refunds by text message or email. If you are due a rebate, you will be notified via your secure online account or by official post.
Government Gateway Accounts Under Attack
