Taxpayers should be wary of any email which claims to emanate from HM Revenue & Customs advising them they are due a refund and asking them to supply their credit card details.
These can be received at both your business Email address and your private Email address (we’ve received them here at Pierce both to our business and private Email addresses) and they do look genuine, however since tax is now primarily self assessed the occasions when HMRC would notify entitlement to a refund are few. HMRC would certainly never ask for credit card details.
If you do receive this or similar scamming emails you should report them to HMRC using the following email address firstname.lastname@example.org. then delete them.
