Almost double the amount has been paid out to people who report suspected tax evasion. While the amounts given to whistleblowers are discretionary in the UK and not on par with the more lucrative system used in the USA, data shows that HMRC paid out nearly £1 million (£978,256) to people who provided actionable intelligence on tax fraud in 2023/24, up from £508,500 the previous year.
