TV presenter wins case against taxman

"HMRC gets that right only 50 per cent of the time when it goes to court, which has to be worrying."

Mr Maley added: "It is, of course, concerning that HMRC can’t seem to grasp the very legislation it designed and attempts to police.

"With further reform on the horizon, this case emphasises the importance of being confident in IR35 status, irrespective of whether you’re a contractor, an agency or end-client."

During the debate Mr Killen admitted that HMRC’s guidance and tools "are far from 100 per cent effective, and there is a lot of complex case law".
