Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate his Department has made of the cost to the public purse of non-structural tax reliefs in (a) 2018-19 and (b) 2019-20; and if he will place a copy of those estimates in the Library.

Information on the costs of reliefs is available on GOV.UK: https://www.gov.uk/government/statistics/main-tax-expenditures-and-structural-reliefs. These statistics, published annually by HMRC, contain estimates of the costs of non-structural tax reliefs. The estimates reflect the total amount by which users benefit from each relief and not the gain to the Exchequer should the relief be removed. Some reliefs are uncosted, usually due to data limitations.
