Research and Development (R&D) Relief is a Corporation Tax relief that may reduce your company or organisation's tax bill by more than your actual expenditure on allowable R&D costs.
The HMRC R&D Relief calculator will help you calculate qualifying R&D expenditure and how much relief, if any, you can claim for your small or medium-sized (SME) company or organisation.

The calculator is for small and medium-sized companies and organisations. It will help you decide what qualifies as allowable expenditure for R&D purposes and how much relief, if any, you can claim under either the SME or Large Company Schemes.
There are two version of the calculator. To decide on which one to use, you need to know exactly when your company or organisation incurred the R&D expenditure. (This may mean more than one calculation for a single Corporation Tax accounting period).
The calculator also includes links to more detailed guidance held in the HMRC Corporate Intangibles Research & Development (CIRD) manual. Please make sure you follow the links and read the guidance as you work through the calculator to ensure you use the correct figures and get the right answer.
