R&D tax relief for small companies: do you qualify?
R&D tax relief is one of the most valuable reliefs in the tax system, and also one of the most misunderstood. Plenty of companies that qualify never claim because they assume it is only for laboratories and people in white coats — and a few that do claim get it wrong. Here is how it works now, and how to tell whether it applies to you.
What R&D tax relief is
R&D tax relief rewards companies that try to advance science or technology by resolving genuine technical uncertainty. It is a corporation tax relief: it reduces the tax bill of a profitable company, and for a loss-making one it can produce a cash credit from HMRC. The key test is not whether you invented something famous, but whether you were trying to solve a problem that a competent professional in the field could not easily work out, and where success was not guaranteed.
How the merged scheme works
The rules changed significantly. For accounting periods beginning on or after 1 April 2024, most companies claim under the merged RDEC scheme, which replaced the separate schemes for small and large companies. It gives a 20% above-the-line credit on qualifying R&D expenditure. Because that credit is itself taxable, the net benefit works out at roughly 15% to 16% of qualifying spend, depending on whether you pay corporation tax at the main rate or the small profits rate.
Extra help for R&D-intensive loss-makers
There is a more generous route for smaller, research-heavy companies that are not yet profitable. A loss-making SME that is R&D-intensive — broadly, where qualifying R&D is at least 30% of total expenditure — can claim under Enhanced R&D Intensive Support (ERIS) instead. This is worth more, with a net benefit of around 27% of qualifying spend, reflecting the fact that early-stage, research-led companies often have no profits to relieve but very real costs.
What actually qualifies
The common myth is that R&D means a laboratory. In reality, qualifying work turns up across software development, engineering, manufacturing, food production and many other fields — anywhere a company is genuinely trying to do something that has not been done in a straightforward way before. What matters is the technical uncertainty and the attempt to resolve it, not the industry. The project does not even have to succeed to qualify.
Equally, a lot of ordinary work does not qualify: applying known techniques, cosmetic changes, or routine development where the answer was already clear. This is exactly the line HMRC looks at.
A word of caution
R&D relief has been through a period of abuse and HMRC has responded by tightening the rules and increasing scrutiny, including a requirement to notify some claims in advance and to submit detailed supporting information. That does not mean genuine claims should be avoided — far from it — but it does mean a claim needs to be properly scoped and evidenced. A loose or overstated claim now carries real risk.
If your company solves hard technical problems as part of what it does, R&D relief is well worth investigating, and it sits alongside other reliefs such as capital allowances and sensible year-end planning. We help companies across Garforth, Leeds and West Yorkshire work out whether their work qualifies and, where it does, build a claim that stands up to scrutiny. If you have never looked into it and you think you might qualify, it is worth an honest conversation.
