The definition of research and development – as described by HMRC

  1. R&D for tax purposes takes place when a project seeks to achieve an advance in science or technology.
  2. The activities which directly contribute to achieving this advance in science or technology through the resolution of scientific or technological uncertainty are R&D.
  3. Certain qualifying indirect activities related to the project are also R&D. Activities other than qualifying indirect activities which do not directly contribute to the resolution of the project’s scientific or technological uncertainty are not R&D.
"Innovation should not feel like a financial risk. R&D tax credits help turn your ideas into progress with less pressure."

Frequently asked questions

Research and development (R&D) tax credits are a government incentive designed to reward UK companies for investing in scientific or technological innovation. They are a valuable source of relief for businesses to use to invest and ultimately continue growing.

Companies that spend money on qualifying R&D activities can make an R&D tax credit claim to receive either a cash payment and/or Corporation Tax reduction. 

What is a qualifying R&D activity?

  • Creating new products, processes or services.
  • Changing or modifying an existing product, process or services.

From 1 April 2024, there are two Research & Development tax credit schemes; the Merged Scheme and the Enhanced R&D Intensive Support (ERIS) Scheme. The majority of UK companies will qualify for the Merged Scheme, with those devoting significant amounts of a company’s total time and costs to R&D qualifying for the ERIS Scheme. Please see contact us for more information.

Any UK limited company that is subject to corporation tax and has;

  • Carried out qualifying R&D activities.
  • Spent money on qualifying R&D costs.
  • Staff costs including Employers Class 1 NIC and Employers pension contributions.
  • Subcontractor costs.
  • Testing costs.
  • Cost of materials.
  • Water, fuel or power consumed in the R&D process.

Most companies with eligible R&D projects can claim up to 16% of additional relief for qualifying costs, with further relief available for companies who devote significant time and expenditure towards R&D.
