R&D tax relief
R&D Tax Relief
R&D tax relief gets money back for work you've already done, even if it never felt like research to you. The bar is HMRC's test: an advance in a field of science or technology, not just in your own company's knowledge, and it isn't limited to laboratory science. It fits companies that have already spent money solving something difficult, whether or not they've ever claimed before.
Recognition
You've solved a genuine technical problem, and nobody called it research
R&D for tax purposes doesn't need a dedicated lab team. Qualifying work can happen inside normal delivery, but only if it meets HMRC's test, set out below.
HMRC's latest statistics, published 29 September 2026, put 2024-25 at 40,325 claims and £8.2bn of relief across all schemes, provisional figures (HMRC, R&D Tax Credits Statistics: September 2026).
Why it happens
The bar is an advance in the field, not just for your company
HMRC's guidelines define the advance a project has to seek as "an advance in overall knowledge or capability in a field of science or technology (not a company’s own state of knowledge or capability alone)". The work also has to resolve an uncertainty, and HMRC says uncertainties that "can readily be resolved by a competent professional working in the field" don't count (HMRC, guidelines on the meaning of R&D). So working something out that was new to your team isn't enough on its own. The question is whether the answer was already known, or readily deducible, by a competent professional in that field. The test applies in any field of science or technology, so process, materials or internal tooling work can qualify where it meets it.
Where this fits
Supporting growth, specifically for R&D-heavy businesses
This is for businesses that have already spent money solving technical problems and want that reflected in what they owe HMRC, or borrowed against once verified. If the growth need is card-based operational spend instead, see Business Credit Cards.
Specialist insight
If you're profitable, the advance-funding market wasn't written for you
Almost everything published about R&D advance funding assumes you're loss-making and need the cash just to keep going. Profitable companies get treated as an afterthought, if they're mentioned at all. But the relief works differently when you're profitable: it reduces what you owe HMRC rather than paying out a lump sum, which changes what a lender can actually advance against, and how the numbers work out.
One thing we've noticed: HMRC's own compliance activity has stepped up in recent years, and the claims that draw scrutiny are rarely the ambitious ones. They're the thin ones. A boilerplate technical narrative that could describe almost any project is a bigger red flag than a genuinely uncertain but well-documented one. Specificity is what protects a claim, not caution.
Decision helper
What typically fits
Being unsure whether your work counts is usually a reason to check, not skip it
Companies that have already spent real money solving a genuine technical problem, in software, process, product, or materials, and haven't claimed for it or aren't sure whether their work counts. If you're unsure, that's usually a sign it's worth a proper look, not a reason to assume it doesn't qualify.
Alternatives and limitations
Advance funding follows a claim, and the adviser matters
Advance funding is usually arranged once a claim exists, rather than as a standalone product: lenders advance against a claim that's filed or close to it (see how R&D advance funding is structured). And choosing an adviser matters. Advisers who interact with HMRC on a client's behalf now fall under a formal registration requirement under section 223 of the Finance Act 2026 (Part 7): an unregistered adviser may not interact with HMRC unless an exception in Schedule 20 applies, so it's worth checking before you instruct anyone. See R&D claim services for the detail.
