R&D tax credits are calculated based on the qualifying R&D expenditure, which includes costs such as staff salaries, subcontractor fees, materials, and software. The applicable tax relief rate depends on whether the business is an SME or a large company, with SMEs typically receiving a higher rate of relief.

Activities that qualify for R&D tax credits typically involve problem-solving, innovation, or technological advancements. Examples include designing and testing prototypes, developing new software algorithms, or improving manufacturing processes to enhance efficiency and reduce waste.

The amount your business can claim depends on the qualifying R&D expenditure and the applicable tax relief rates. SMEs can typically claim up to 25% of their R&D costs. If you’re loss-making, you can claim a maximum of 33%.

If your SME makes a profit, you can claim up to 25p on every £1 spent on research and development. The claim on R&D tax credits can cut your corporation tax bill by deducting the eligible R&D expenditure from your annual profit, which could save you 230% in total.

 A loss-making SME can claim back up to 33p in every £1 of qualifying expenditure and surrender the loss for a cash tax credit at a rate of 14.5%.

Large companies can claim up to 11p for every £1 of qualifying spend.

R&D tax credits effectively reduce a company’s taxable profits, so they are not considered taxable income. However, if your business receives a cash repayment as a result of the tax credit, it may be subject to tax in subsequent years.

R&D tax credits were first introduced in the UK in 2000 for SMEs and in 2002 for large companies. The scheme has since undergone several changes to improve its effectiveness and accessibility for businesses.

Upon submitting a successful R&D tax credit claim, businesses typically receive their tax credits within 28 days. However, in some cases, it may take longer if HMRC requires further clarification or documentation.
