When an email arrives from the tax man, it can often provoke an emotional reaction. Fear – do I owe them a lot of tax? Anticipation – are they offering to refund me a lot of money? Confusion – I thought I had sorted out my tax return already this year! Scammers know that any communication from HM Revenue & Customs (HMRC) is likely to get your attention. This is why they are increasingly sending fraudulent emails and SMS-messages, purporting to be from HMRC. The scam messages promise tax rebates in an attempt to trick you; they want you to share your personal financial details, including bank account numbers. Getting hold of your personal data is how they rip you off.
