Ninety Premier League footballers are being investigated by HMRC as a result of suspected tax evasion, according to The Sun.
The department is also said to be looking into 38 clubs, as well as 13 agents.
Inspectors are of the view that many players have companies set up in tax havens for the sole purpose of getting paid through image rights as opposed to wages.
The two have been viewed as separate income streams since a ruling was passed in 2000.
Back in January, HMRC indicated that 43 players were under investigation, but in a recent update, revealed that the number had more than doubled.
