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 genuine technical uncertainty, not novelty to the world, and it covers far more than 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

In our experience, most companies underclaim rather than overclaim, because they assume R&D means a dedicated lab team, when most qualifying work happens inside normal delivery.

Why it happens

The bar is uncertainty, not novelty to the world

If your team had to genuinely work out how to do something, rather than just look it up, and it wasn't obvious in advance whether it would work, that's usually enough to qualify. This applies well beyond software and manufacturing: process changes, material substitutions, and internal tooling built to solve a real problem all show up in real claims.

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.

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 the Finance Act 2026, Part 7 (Schedule 20 sets out the exemptions to it, not the requirement itself), so it's worth checking before you instruct anyone. See R&D claim services for the detail.

Before you get in touch

What information do I need?

To start, just a description of what’s actually happening in the business. If it progresses, the specialist partner will ask for the usual things: recent accounts, a sense of turnover and trading history, and details of the specific need.
