The HMRC are chasing £1.9bn that could potentially be owed in taxes by the UK’s richest population.
The National Audit office have said that the HMRC’s specialist unit recovered £416m in 2015 from 6,500 of high earners with wealth of more than 20m.
Each of the 6,500 high earners has been assigned their own HMRC official to liaise with over their tax bill.
The estimated £1.9bn to chase includes tax avoidance schemes that are marketed at wealthy investors, of which many have been open cases for many years.
NAO have said that the HMRC are currently investigating the potentially criminal activity of 10 high net worth individuals involving illegal offshore tax evasion. However, only one has been found guilty since 2010.
A leak of records from law firm Mossack Fonseca has revealed how the rich use tax havens to hide their wealth. According to a NAO report, 40 of the wealthiest group were identified in the leaked data. The report has also revealed that 137 of the country’s richest who had undisclosed assets in Liechtenstein used an agreement with the tax haven in 2009 to admit their liabilities in return for less harsh penalties.
