HM Revenue and Customs (HMRC) is calling on Self Assessment customers to remain
vigilant as scam attempts continue.
Customers urged to be alert to bogus tax refund scams and phishing attempts.
Report any suspicious emails, texts or calls to help stop fraudsters in their tracks.
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.
Concerned customers reported more than 170,000 scam referrals to HMRC in the 12 months to 31
July 2025 — and while that is a 12% reduction compared to the previous year, more than 47,000 of
these reports still involved fake tax refund claims. 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.
Anyone due a refund can claim it securely via their HMRC online account or via 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.
