HMRC has published guidance enabling businesses and individuals to confirm whether someone claiming to represent the tax authority is genuinely an HMRC officer or collector. The guidance sets out the verification steps you should take when HMRC staff visit you in person, helping protect against fraudulent callers impersonating tax officials. This information is relevant to anyone who may be approached by individuals claiming to act on behalf of HMRC.
