THE tax affairs of more than 4,000 Britons with an HSBC bank account in Jersey are under scrutiny after their details were leaked to HM Revenue & Customs.
The list, which was passed to authorities this week by a whistleblower, reportedly includes the names of serious criminals.
It will raise further questions about HSBC’s procedures at a time when the group is facing fines of about $1.5bn in the United States for breaching money laundering rules.
Banks are required to report any suspicious activity that could suggest money laundering, although the responsibility for paying tax lies with the individual.
According to The Daily Telegraph, the list identifies the names, addresses and account balances of 4,388 UK people holding £699m in offshore bank accounts at HSBC Jersey.
The list will now be used by HMRC to identify whether any of the accounts were used to avoid paying taxes.
HMRC said: “We can confirm we have received the data and we are studying it. We receive information from a very wide range of sources which we use to ensure the tax rules are respected.”
