Scams warning as self assessment taxpayers targeted 22 Aug 2025HMRC is calling on self assessment taxpayers to remain vigilant to scams that claim to be from the department. It says that scammers often impersonate HMRC, offering fake refunds or demanding urgent payments to steal personal and banking information. 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 taxpayers spot scams more easily 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.'
