Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what recent estimate he has made of the loss to the Exchequer of tax revenue through tax scams.

The information requested is not available as HMRC does not make an estimate of the amount of revenue lost through tax scams.

HMRC estimates the tax gap which is the difference between the amount of tax that should, in theory, be paid to HMRC, and what is actually paid. For the tax year 2019-20, the tax gap arising from criminal attacks on the tax system was £5.2 billion.
