HM Revenue & Customs (HMRC) claimed that Mr Barnes, widely known as "the voice of rugby," evaded tax payments between 2013 and 2019 while working as a freelancer for Sky TV.
The former professional rugby player had previously won a legal case against HMRC last year at the First Tier Tribunal, which initially allowed him to avoid a £695,000 tax bill.
However, HMRC successfully appealed this decision, and the Upper Tribunal reversed the original verdict on Thursday.
According to The Telegraph, the latest ruling determined that Barnes should have been paying employment tax during his six years at the broadcaster.

The current 36-man British & Irish Lions squad for 2025, according to the bookies
We found it intriguing to project a smaller squad based on the favored contenders according to bookmakers' odds as of April19, 2024.
The Lions will play a New Zealand and Australia invitational XV as part of their nine-match tour down under in 2025.
The historic fixture in Adelaide will precede Test matches with the Wallabies in Brisbane, Melbourne and Sydney.
A sell-out at the 100,000-capacity Melbourne Cricket Ground would smash records for a Lions Test match.
The series finale will be played in front of more than 80,000 fans in Sydney's Olympic Park.

Don’t think many people will have doubts about Andy Farrell being named British and Irish Lions head coach. He’s earned it. Looking forward to all the petty squabbling over squad selection on here in 2025. If this wretched app still exists by then…
