UK R&D Tax Credit rates for pre-April 2023 expenditure

SME R&D Relief helps businesses reduce their taxable profits. HMRC allows businesses to deduct an extra 130% on qualifying R&D expenditure costs from the annual profits on their corporation tax bill.

For example, if you have spent £100 on qualifying R&D your additional enhancement would uplift this to an extra £130. Corporation tax in the UK is currently 19%, meaning that you would receive an extra £24.70 through R&D Tax Credits.

SME R&D Relief also helps loss-making companies, who can surrender their losses in exchange for a cash payment worth £33.35, based on a credit rate of 14.5%.

Loss-making businesses can claim 230% of their qualifying R&D expenditure. For example, for £100 spent on R&D costs you’d get an extra £130 uplift, resulting in £230 of enhanced expenditure. When the 14.5% credit is applied to this enhanced expenditure you’d receive £33.35 through R&D Tax Credits.

Profitable businesses can therefore claim up 21.50p of every £1 spent on R&D Activity. For example, if you spend £100 spend on eligible R&D, your additional uplift would now be £86. If your company pays the 25% corporation tax rate, you’d receive £21.50 through R&D Tax Credits.

Loss-making businesses will be able to claim 186% of qualifying R&D expenditure. The 10% credit rate will result in £18.60 of R&D Tax Credits for every £100 spent.
