HMRC warns of fake rebate emails The revenue body said that last year it noticed a spike in the number of a phishing emails being reported after the self-assessment deadline. HMRC took action to close down 522 illegal sites in 2012, which showed these emails originated from countries including the United States, Russia, Japan, as well as various parts of central and eastern Europe. The emails often begin with a sentence such as: "We have reviewed your tax return. According to our calculations of your last year's accounts, a tax refund of (an amount) is due. The self-assessment deadline day was on January 31, when a record 9.61 million people filed their tax returns on time this year. Legitimate information about tax rebates will be sent out in the coming weeks, but this will arrive in the post and not on email. Genuine tax rebate forms, known as P800s, will never ask for credit or debit card details. HMRC said the scam is a persistent one, with similar numbers of phishing emails having been recorded over the last couple of years, although the numbers will be the tip of the iceberg as many emails go unreported. Anyone who receives such an email should delete it and report it, but must never try to reply, HMRC said. The revenue body advises that anyone who believes they may have fallen victim to an email scam should tell their bank and card issuer as soon as possible.
