Question to the HM Treasury:

To ask the Chancellor of the Exchequer, for which tax reliefs he estimates that more than 50 per cent of the total impact accrues to fewer than 10 percent of claimants.

It is not possible to provide this information for all tax reliefs. Information on how the impact of some of the largest tax reliefs are distributed among claimants is set out in HMRC's annual Tax Relief Statistics publication, last released on 22 January 2026, and can be found here:
