HM Revenue and Customs (HMRC) are warning tax credit claimants about fraudsters who are targeting people with scam emails, fake websites and text messages.

Scam emails double during the tax credits renewal period which runs until the deadline on July 31.

New statistics show that nearly 51,000 phishing emails were reported to HMRC between April and July last year – double the number for the same period in 2013.

Some of these scam messages claim to be from a “Tax Credit Office Agent” offering a tax refund, or include a link to a fake version of the GOV.UK website. People are often asked to provide bank details or other sensitive information such as passwords. Fraudsters then try to take money from their account, or sell their identities to criminals.

Last year, HMRC worked with other agencies to shut down 8,877 of these scam websites – a 500 per cent increase against 2013’s figures – and the message to tax credits customers this year is to stay vigilant.

Nick Lodge, director general of Benefits and Credits, HMRC, said: “HMRC will never ask people to disclose personal information by email. We have cracked down on phishing emails and scam websites, but the fraudsters’ methods are constantly changing, so people must remain vigilant.

“The only way to renew tax credits and report changes online is on GOV.UK.”
