The Welsh Labour politician said: “I have been made aware of this scam, which on the face of it looks like an official email from the Crown.
"The message says that the recipient is entitled to a significant amount, often hundreds of pounds, in tax returns, but it’s merely a ruse designed to con you into giving personal details.
“Any legitimate tax return due to you will be in the form of a letter and enclosed cheque, and you should never give card or bank information online in this way. It all looks above-board, but I cannot stress enough how important it is not to be hoodwinked.”
The email invites the recipient to follow a link and input personal details onto a form which uses HMRC logos and, on first inspection, looks official.
“If you are ever in any doubt about the authenticity of emails like this, especially when large sums of money are promised, you should check with HMRC or seek advice from Trading Standards before proceeding,” said Mr Skates.
