Top Premiership footballers like Wayne Rooney and Gareth Barry are avoiding millions of pounds in tax through a loophole which means they can pay 22% on wages.
They are using complex tax avoidance schemes that allows them receive earnings from image rights into a 'shell' company, where they pay business, rather than personal, tax rates.
The Sunday Times has uncovered 55 players who are taxed at just 22% because they get a large proportion of their total earnings from their image rights companies.
The newspaper said that Manchester United star Rooney has saved almost £600,000 over the past two years by using the tax loophole.
Manchester City's Barry took home £135,000 more than if he had paid income tax at 40%.
Now the taxman has demanded the clubs pay £100m on behalf of their players as HM Revenue & Customs (HMRC) investigates how to stop the arrangement.
The players uncovered as taking advantage of the gap in the tax rules include England and Chelsea defender Ashley Cole, former husband of singer Cheryl, Manchester United's Rio Ferdinand, and his team-mate Michael Owen whose company Owen Promotions owns 11 racehorses.
Arsenal's Theo Walcott has TJW (Promotions) while David James, the former England goalkeeper has Toocoo.
Scores of top footballers launched their own companies eligible to take image rights payments after Labour Chancellor announced the 50p top rate tax.
The players have two contracts with their clubs. They get a salary as a player and the other is for 'image rights' - earnings from shirts and other merchandising. These royalties are paid into a company which is only liable for 28% corporation tax rather than the 50% income tax.
And players can take out loans from their companies where they only pay 2% tax on the sum because it is regarded as a benefit in kind.
Investigations by the Sunday Times showed the £200,000-a-week Rooney, Barry and Chelsea's Daniel Sturridge took advantage of this tax loophole. HMRC have confirmed they are looking at players' companies as part of their probe into image rights and tax avoidance.
They have demanded the money from the soccer clubs to make up for the shortfall in tax revenues after they overstated the proportion of players' income that was coming from image rights.
The practice is also used in other well-paid industries that are exposed to higher tax rates, such as banking and IT. The practice was highlighted by This is Money in 2009.
