Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate his Department has made of the level of tax (a) evasion and (b) avoidance in each of the last four years.

HM Revenue and Customs (HMRC) estimates the size of the tax gap, which is the difference between the amount of tax that should theoretically be paid to HMRC and the amount that is actually paid. The latest tax gap estimate for 2021-2022 is a record low of 4.8 per cent of total theoretical tax liabilities. The tax gap statistics are published annually and are available at: https://www.gov.uk/government/statistics/measuring-tax-gaps.
