Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how much revenue the Government has raised through tackling tax avoidance, evasion and non-compliance since 2010.

Compliance yield is HMRC’s term for money that would have been lost to the Exchequer if not for our compliance work. This is published each year in HMRC’s Annual Report and Accounts.

More about the different components that are included in the reported amount can be found in the HMRC Compliance Yield: technical note, that is published each year alongside the Annual Reports and Accounts.
