Blunt deposited more than £2m (€2.5m) in the offshore tax haven and registered the account at his parents' British address.
The pop star has previously denied he is a tax exile after buying property in Switzerland and states on official company records that he is "British".
His management company has declined to comment on his tax and financial affairs and it is not known if the Jersey account has been declared to the British tax authorities. There is no suggestion he has done anything illegal.
Yesterday it emerged that a whistleblower provided HMRC with full details of every HSBC client who has an account in Jersey.
More than 4,000 British-based people, including several serious criminals who bank with HSBC in Jersey, are now embroiled in a major tax investigation.
HMRC warned it would "come down hard" on individuals evading tax and urged anyone banking with HSBC in Jersey who had not made the necessary legal disclosures to come forward. It is expected to set up a dedicated phone line this weekend. (© Daily Telegraph, London)
