The tax authority says that scammers often impersonate HMRC, offering fake refunds or demanding urgent payments to steal personal and banking information.
More than 170,000 scam incidents were reported to HMRC in the 12 months to 31 July 2025, and 47,000 of these reports involved fake tax refund claims.
HMRC will never:
• leave voicemails threatening legal action or arrest
• ask for personal or financial information via text message or email
• contact customers by email, text, or phone to inform them about a refund or ask them to claim one.
Anyone due a refund can claim it securely via their HMRC online account or via the HMRC app.
HMRC says that filing early can also help, as those who have already submitted their tax return are less likely to be caught off guard by scam attempts closer to the self assessment 31 January 2026 deadline.
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."
