R&D Tax Relief — You Probably Qualify. Nobody's Told You.

Most agency owners have never thought about R&D Tax Relief.

Most agency owners are wrong to dismiss it.

R&D Tax Relief is not just for laboratories. HMRC's definition of qualifying R&D includes activities that seek to achieve an advance in technology through the resolution of technical uncertainty.

In plain English: building something that didn't exist before. Solving a technical problem that existing solutions couldn't handle. Developing a process through genuine trial and error.

If you run a digital or marketing agency and you've ever built something bespoke, there's a reasonable chance you've been leaving money on the table.

"The question costs nothing. The answer could save thousands."

What R&D Tax Relief Actually Is

R&D Tax Relief is a UK government incentive that allows companies to claim back a portion of their qualifying R&D expenditure against their corporation tax bill. For SMEs, this can significantly reduce or eliminate a CT liability — or in some cases generate a cash repayment.

The relief isn't new. But the number of agencies that have never had the conversation with their accountant is surprisingly high.

Part of the problem is the name. "Research and development" sounds like it belongs in a pharmaceutical company or a software house with a dedicated engineering team. For most agency owners, it doesn't feel like it applies to them.

That assumption is costing some of them thousands of pounds a year.

What Actually Qualifies

HMRC's definition is broader than most people expect. The key test is whether work involved technical uncertainty — meaning you couldn't know in advance whether what you were trying to build would work, and you had to iterate to find out.

For agencies, that can include:

Custom reporting tools and dashboards built specifically for a client where off-the-shelf solutions didn't exist or couldn't do what was needed.

Proprietary automations developed to solve a process problem — where the solution required genuine technical problem-solving rather than configuring existing software.

Bespoke technology built as part of service delivery — tools, platforms or integrations that involved meaningful development work and weren't simply bought in.

Technical processes developed through genuine iteration — where the outcome was uncertain and required testing, failing and adjusting to reach a solution.

If any of that sounds familiar, the conversation with your accountant is overdue.

What Changed in 2023 and 2024

The R&D tax relief landscape changed significantly following HMRC reforms in 2023 and 2024. The previous SME and RDEC schemes were merged into a single scheme, and the rates and eligibility rules were updated.

This is important for two reasons. First, if you've claimed before, the rules you claimed under may no longer apply in the same way. Second, if you've never claimed, the current scheme is the one to assess against — not older information you may have read.

R&D claims are complex. HMRC scrutiny has increased significantly in recent years following a period of widespread overclaiming in the market.

Do not attempt to submit without specialist advice. But equally — do not assume you don't qualify without asking the question first.

Your Checklist

• Think through the last two years — have you built anything genuinely novel or solved a technical problem through iteration?

• List any bespoke tools, automations or processes developed as part of client delivery

• Ask your accountant one question: have you ever assessed whether we qualify for R&D Tax Relief?

• If the answer is no — request they review it or refer you to a specialist

• Document any technical challenges solved in the last two years — these may be qualifying activities
  

Three Things to Do This Week

1. Ask your accountant this week: have you assessed whether we qualify for R&D Tax Relief? If the answer is no — that conversation is long overdue. It costs nothing to ask and the potential upside is significant.

2. Document any technical work done in the last two years that involved genuine uncertainty or innovation. Even informal notes are a starting point. Think about the projects where you weren't sure it would work until you'd built and tested it

3. Don't dismiss it until it's been properly assessed. The cost of asking is zero. The potential saving — if you qualify — can run to tens of thousands of pounds. That's worth one conversation.

The agencies that claim R&D Tax Relief aren't doing anything unusual. They're just asking the question.

Most agency owners haven't asked. If that's you — this week is a good time to change that.
