Continuing with the theme of reform to the UK’s R&D tax relief regime which began in the 2022 Autumn Statement, the SME and large company regimes are to be merged, as planned, from 1 April 2024. However, the Chancellor did not specify the rate(s) of relief which will be available under the merged scheme, which is likely to be announced in the 2024 Spring Budget.
In our submission to the House of Lords Finance Bill Sub-Committee inquiry into draft Finance Bill 2023/24, Chartered Accountants Ireland recommended that the commencement date for the introduction of a single unified scheme be deferred beyond 2024 to allow for a longer period of consultation to be undertaken on the potential options available.
Other changes to the R&D tax relief regimes were also announced today. The intensity threshold in the R&D intensives scheme is to be reduced from 40 percent to 30 percent for accounting periods that commence on or after 1 April 2024. A one-year grace period will also be introduced which will allow companies who dip under the 30 percent threshold to continue to receive relief as an R&D intensive company for a further year.
More details of the changes to R&D tax relief announced are available in a HM Treasury policy paper with confirmation that all changes come into effect in respect of accounting periods beginning on or after 1 April 2024.
