    What is R&D Tax Relief?

    R&D (Research and Development) tax relief is a UK government incentive designed to support innovation. It allows eligible UK companies to reduce their Corporation Tax bill, or in some cases, receive a cash credit, in recognition of qualifying R&D activity.

    The relief is intended to help offset the costs of innovation, including staff time, subcontractors, software, consumables and utilities, where those costs relate directly to R&D.

    How Does it Work?

    As of 1 April 2024, most UK companies now claim R&D tax relief through RDEC, replacing the previous SME and RDEC routes.

    Relief is typically worth around 15% of qualifying R&D expenditure for profit-making companies (after tax), 16.2% as a cash credit for loss-makers or up to 27% for R&D intensive loss makers.

    Enhanced Support (ERIS)

    Loss-making SMEs that spend at least 30% of their total costs on qualifying R&D may be eligible for Enhanced R&D Intensive Support. ERIS is not available to large companies.

    This can increase the cash credit rate for these loss-making SMEs to around 27%.

    What if I received a grant or subsidy?

    Even if your R&D is subsidised, for example through a grant, you can still claim under RDEC. The old restrictions on SME claims for subsidised projects no longer apply.
