HMRC warns Self Assessment customers over surge in scam attempts

HM Revenue and Customs (HMRC) has issued a warning to millions of Self Assessment customers to remain vigilant against scams as fraudsters continue to impersonate the department in an effort to steal personal and financial information.
Scammers are known to offer fake tax refunds or demand urgent payments while claiming to be HMRC. The aim is often to trick people into sharing sensitive data such as passwords, usernames, or access codes. HMRC has stressed these details should never be shared, even with someone the customer knows or trusts.
The warning comes as the 31 January 2026 deadline for filing Self Assessment tax returns approaches. HMRC said filing returns early can help customers reduce the risk of falling for scams, as those who have already filed are less likely to be caught off guard by phishing attempts closer to the deadline.
Figures show that from August 2024 to July 2025, HMRC received more than 170,000 scam referrals from concerned customers. While this represents a 12% drop on the previous year, more than 47,000 of those reports related specifically to fake tax refund claims.
HMRC stressed it will never:
- Leave voicemails threatening legal action or arrest
- Ask for personal or financial details by text message or email
- Contact customers via phone, text or email to offer or request a tax refund.
Instead, anyone due a refund is advised to claim securely via their HMRC online account or the free HMRC app.
Kelly Paterson, HMRC’s Chief Security Officer, said: “Scammers target individuals when they know Self Assessment customers will be preparing to file their tax returns. We’re urging everyone to stay alert to scam emails and texts offering fake tax refunds.
“Taking a moment to pause and check can make all the difference. Report any suspicious activity to us before the fraudsters do any more harm. Search ‘HMRC scams advice’ and refer to the scams guidance on GOV.UK to stay informed and protect yourself.”
Customers are encouraged to report phishing attempts directly to HMRC by:
- Forwarding suspicious emails to phishing@hmrc.gov.uk
- Forwarding scam text messages to 60599
- Reporting scam phone calls through GOV.UK.
