The UK R&D Tax Incentive regimes are designed to promote private sector investment in innovation.

Small and Medium-sized Enterprises (SMEs) can claim under the R&D tax credit scheme, whereas large companies (and SMEs carrying out funded or contract R&D) can claim under the Research and Development Expenditure Credit scheme (RDEC). For expenditure incurred prior to the 1 April 2023, SMEs can claim up to 33p for every pound of eligible expenditure on in-house, unfunded R&D, and can receive a cash payment even if they are loss-making or pre-trading.  

Over recent Fiscal Events, the Government has announced a raft of changes to the R&D tax relief schemes, including changes to the rates of R&D tax relief available. These affect current claimants of R&D tax relief under both the SME and RDEC schemes and apply to expenditure incurred on or after 1 April 2023. For expenditure incurred on or after this date, a company claiming under the SME scheme can receive relief of up to 27p for every pound of eligible expenditure incurred.  The precise rate of relief available, which can range from 18.6p to 27p, will be dependent on the claimant company’s circumstances.  With regards to the RDEC scheme, for expenditure incurred on or after 1 April 2023, the effective rate of relief will be 15p for every pound of eligible expenditure incurred.

In addition, for accounting periods starting on or after 1 April 2024, all R&D claimants that do not qualify as R&D intensive SMEs will move to claim under the Single Merged R&D Scheme, with the effective rate of relief mirroring the aforementioned RDEC rate, i.e. 15p for every pound of eligible expenditure incurred.

With all of these changes, it is easy for prospective claimants to be confused.  Our specialist Innovation Taxes Team can help you navigate the complexity and ensure that your company is claiming the relief to which it is entitled.  We offer a range of R&D Tax Incentive Services, from feasibility studies to full claim preparation - find out more.
