Question to the HM Treasury:

To ask the Chancellor of the Exchequer, if he will make an estimate of the revenue received by the public purse through (a) compliance yield as measured for performance purposes and (b) tax revenue as measured by tax receipts raised as a result of new spending on compliance activity announced in each (i) a Budget and (ii) Autumn Statement in the last five financial years.

At each fiscal event the Government publishes a table of the impacts of its policy and operational decisions certified by the Office for Budget Responsibility. Measures which raise tax revenue from compliance activity are generally part of our “Tackling the tax gap” package at each fiscal event. Most recently this was set out in Table 5.1 of Autumn Statement 2023, and is available for previous years on GOV.UK.
