What is R&D Tax Relief

R&D tax relief is a UK government incentive that reduces corporation tax for businesses investing in research and development. The scheme allows businesses to recover part of the costs involved in developing new or improved products, processes, or technology.

Qualifying R&D expenditure can include staff salaries, third party costs, materials used in development, and certain software used during R&D projects.

For businesses that are not yet profitable, the scheme can provide a payable cash credit based on eligible R&D spending.
