Some of the U.K. biggest names in business, entertainment and sport will soon be receiving letters from HM Revenue and Customs (HMRC) demanding payment of disputed tax bills.
Under a new finance law about 33,000 people who invested in tax avoidance schemes will be affected.
Among them is David Beckham. They will be asked to pay the disputed tax within 90 days of receiving the letter.
They will only get the money back if the dispute is eventually settled in their favor.
