The Revenue said that fraudsters are using email and text messages to trick people into thinking they have received a tax rebate, causing them to hand over their personal and account details.
Treasury minister Mel Stride said, “HMRC only informs you about tax refunds through the post or through your pay via your employer. All emails, text messages, or voicemail messages saying you have a tax refund are a scam. Do not click on any links in these messages and forward them to HMRC’s phishing email address and phone number.
“We know that criminals will try and use events like the end of the financial year, the self-assessment deadline, and the issuing of tax refunds to target the public and attempt to get them to reveal their personal data. It is important to be alert to the danger.”
HMRC said that in March, it requested 2,672 phishing websites be taken down and received 84,549 phishing reports.
The Revenue expects phishing to continue in the coming months as genuine tax refunds for 2017/18 are issued.
Taxpayers who have paid too much tax will receive a letter by post between June an October.
HMRC also urged taxpayers not to give any private information, reply to text messages, download attachments or click on links in emails.
