What are R&D tax credits?

Research and development (R&D) tax credits are a government incentive designed to reward UK companies for investing in innovation. They are a valuable source of funding for businesses to invest in accelerating their R&D, hiring new staff and ultimately growing.

R&D helps drive productivity and economic growth, with benefits for society as a whole. R&D tax incentives encourage businesses to invest in developing new technologies which deliver spillover benefits to the wider economy as well as supporting commercial success.

How do they work?

Companies that spend money developing new products, processes or services, or enhancing existing ones, could be eligible for R&D tax relief.

If you’re investing in innovation, you may be eligible to make an R&D tax credit claim to receive either a cash payment and/or Corporation Tax reduction.

It’s important to understand whether your project qualifies. HMRC provides guidance to help businesses, and issues guidelines on the meaning of R&D for tax purposes.

Claims for accounting periods beginning on or after 1 April 2024 fall under a merged R&D scheme or, for eligible loss-making SMEs, Enhanced R&D Intensive support (ERIS). Claims for periods prior to this are subject to different rules depending on the size of the business.

Is my business eligible for R&D tax credits?

To benefit from R&D tax incentives, you must:

  • Be a limited company in the UK that is subject to Corporation Tax.
  • Have carried out qualifying research and development activities.
  • Have spent money on these projects.

Who qualifies?

UK companies working on innovative projects in science and technology could be eligible to claim R&D tax relief.

R&D takes place in a wide range of industries. It is unlikely that you will be eligible if your activity is not recognised as a scientific or technological innovation. You cannot claim if the advance is in the arts, humanities or social sciences (including economics). 

HMRC also provides information on the types of claim which are rarely eligible, including those from care homes, childcare providers, personal trainers, wholesalers and retailers, pubs and restaurants.

R&D changes and why it’s still worth it

After two decades of relative stability, the early 2020s saw significant changes to R&D tax relief. It resulted in the introduction of the merged RDEC scheme and ERIS, legislative changes and increased HMRC compliance activity.

Some of the key changes relate to the introduction of mandatory documentation:

Innovative companies should not be deterred from claiming. R&D tax relief remains a vital source of funding, and is particularly impactful for loss-making SMEs who meet the threshold for ERIS.

With proactive, tailored advice from a reputable adviser, you can continue to claim R&D tax relief with confidence and receive the full value for your innovation.

What counts as R&D?

If your company is taking a risk by attempting to resolve scientific or technological uncertainties then you may be carrying out qualifying activity. This could include:

Creating new products, processes or services.

Changing or modifying an existing product, process or service.

Within the government’s accepted research and development definition, R&D doesn’t have to have been successful to qualify.

Further detail is available in our KnowledgeBank article:

What costs qualify for R&D tax credits?

Where qualifying activity is being undertaken, certain costs may qualify for R&D tax relief. They fall into the following categories:

  • Staff, including salaries, employer’s NIC, pension contributions and reimbursed expenses.
  • Subcontractors and freelancers.
  • Materials and consumables, including heat, light and power that are used up or transformed by the R&D process.
  • Software licences and certain data and cloud costs.
  • Payments to the subjects of clinical trials.

Eligible projects

Projects can consist of a number of activities conducted to achieve an advance in science or technology. It’s important to get the boundaries of a project right.

While a project should encompass all activities required to resolve the scientific or technological uncertainty, it may be part of a larger commercial project. The wider project is likely to include elements that are not R&D.

Which R&D incentive is right for my business?

The R&D tax scheme that applies to your business depends on your size, the nature of your R&D and the accounting period.

Merged scheme

For accounting periods beginning on or after 1 April 2024, companies of all sizes can claim through the merged R&D scheme.

ERIS

Enhanced R&D intensive support (ERIS) offers loss-making R&D intensive SMEs the opportunity to benefit from an enhanced rate of credit if they meet the threshold for eligibility.

SME R&D tax relief

For accounting periods starting before 1 April 2024, SMEs can benefit from SME R&D tax relief, worth up to 27p for every pound spent on qualifying expenditure between 1 April 2023 and 31 March 2024.

R&D tax credit rates

R&D tax credits are calculated based on your R&D spend in relation to your qualifying activity.

Depending on what incentive you’re claiming under, the rates of R&D relief can vary as shown in the table below.

SME R&D tax incentive RDEC Merged scheme Enhanced R&D intensive support
Company type Before 1 April 2023 After 1 April 2023 Before 1 April 2023 From 1 April 2023 From 1 April 2024 From 1 April 2024
Loss-making SME Up to 33.35% Up to 18.6% 10.5% 15% 16.2%
Profit-making SME Up to 24.7% Up to 21.5% 10.5% Up to 16.2% Up to 16.2%
R&D intensive SME Up to 27% Up to 27%
Large company 10.5% Up to 16.2% Up to 16.2%

How much are R&D tax credits worth?

The value of your claim will be determined by your individual qualifying spend and the incentive that you are claiming under. Although each claim will be unique, HMRC statistics for the tax year 2023 to 2024, indicate that the value of claims under the RDEC scheme have increased.

The average R&D tax credit claim made under the SME scheme was around £85,000, while the average claim under the RDEC scheme was around £438,000.
