According to the National Cyber Security Centre, HMRC was the third most spoofed government body in 2022, behind the NHS and TV Licensing. 

HMRC has issued an alert providing details of a number of new scams that aim to trick people into handing over money or personal information, including claims that a taxpayer's National Insurance number has been used in a fraud.

In the year to April 2023 HMRC responded to 170,234 referrals of suspicious contact from the public. Of these, 68,437 were related to bogus tax rebates.
