        For accounting periods that end on or before 31 March 2024 there are two HMRC schemes for claiming R&D Tax Credits: the SME R&D scheme and R&D Expenditure Credit (RDEC).

        To qualify for the SME R&D scheme, a business generally needs fewer than 500 employees and a turnover of less than €100m or €86m net assets. There is also a subcategory of the SME Scheme for loss-making SMEs that meet a 30% R&D intensity threshold (rising to 40% for accounting periods starting on or after 1 April 2024). Large companies and certain SMEs can claim RDEC.

        A new merged RDEC-like scheme for all will comes into effect for accounting periods starting on or after 1 April 2024.
