An Upper Tribunal case has fined AML Tax (UK), part of Doug Barrowman’s Isle of Man-based Knox Group, for failing to provide HM Revenue and Customs with legally-required information.
The Scottish businessman, who is married to lingerie tycoon Baroness Mone, now faces a £3.3m tax bill as a result.
AML was struck off the Companies House register in 2019 for failing to file accounts. It was a promoter of a loan-based tax avoidance schemes, which recruited thousands of contractors - including doctors, social workers, nurses and IT workers - who later received large bills from HMRC.
