Millions of Self Assessment customers are being urged by HM Revenue and Customs (HMRC) to remain vigilant to scams that claim to be from the department.
Scammers often impersonate HMRC, offering fake refunds or demanding urgent payments to steal personal and banking information.
They may say it’s safe to share personal details. It’s not. Passwords, usernames, and access codes are private and customers should never share them, even with someone they trust or who helps them with their tax.
Filing early can also help customers 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.
If someone receives a communication claiming to be from HMRC that asks for personal details or offers a tax rebate, they should check the official HMRC scams guidance to verify its authenticity.
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
