R&D Tax Credits, Explained
Research & Development Tax Credits are a tax incentive designed to encourage UK companies to invest in R&D. By using R&D Tax Credits, companies can reclaim up to 33% of the costs of their R&D projects.
In effect, R&D Tax Credits allow companies to reduce their corporation tax bill or claim payable cash credits as a proportion of their R&D spend. They can be claimed for the development of a new product, process or service, or improvements to existing ones – even if the work wasn’t successful.
