Official statistics underplay the scale of tax avoidance and evasion
The latest annual estimate by HM Revenue and Customs of the ‘tax gap’ (the difference between the amount of tax owed and the amount of tax paid, ie the scale of non-compliance) is £32bn, or 5.1% of total tax revenues, which is similar to previous years. However, the percentage that is due to fraud is higher than before, at 45%. But these figures significantly underestimate the true scale of non-compliance with the tax system, by leaving out profit-shifting (tax avoidance) by multinational companies, which could cost the exchequer up to £20bn per year, by excluding estimates of error and fraud in the HMRC-administered COVID support schemes, and by ignoring overseas tax evasion (however, in a hopeful sign, the UK government has finally pledged to expose how much money is lost through overseas tax evasion; it is estimated that £570bn is held by UK residents in tax havens.)
