Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how many claims for Research and Development tax credits were made (a) fraudulently and (b) in error since 2010

Estimates of the level of error and fraud in research and development tax credits are published in HMRC’s Annual Report and Accounts. The latest publication can be found on Gov.uk at: HMRC Annual Report and Accounts 2023 to 2024 . The methodology used to calculate the level of error and fraud for 2020-2021 was significantly improved for the 2022-2023 Annual Reports and Accounts.

Estimates of the level of error and fraud in research and development tax credits for earlier years are not available on a comparable basis.
