R&D tax credits for Bristol SaaS: What software qualifies in 2026?

The Bristol tech scene—from the startups in Temple Meads to the scale-ups in the Bristol & Bath Science Park—is built on innovation. If you’re a SaaS company investing time and money into solving complex technical problems, the UK government’s R&D tax credits scheme is designed to reward you. However, the rules changed significantly in April 2024, impacting claims made in 2026.

As a specialist SaaS Accountant Bristol firm, EasyAccounts and Tax Ltd helps local developers navigate these changes to secure the funding they need to grow. Here is your 2026 guide to what software projects actually qualify.

The 2026 Landscape: The Merged Scheme

First, the basics. For accounting periods starting from 1 April 2024 onwards, the old SME and RDEC schemes have been merged . Most Bristol SaaS companies will now claim under a single RDEC-style scheme, with a credit rate of 20% of your qualifying R&D expenditure . There is also an Enhanced R&D Intensive Support (ERIS) for loss-making companies that spend at least 30% of their total expenditure on R&D .

So, What Software Qualifies?

HMRC isn’t looking for just “hard work” or “business risk.” They are looking for projects that sought to achieve an advance in technology by overcoming a technological uncertainty that a competent professional in your field couldn’t easily solve .

✅ Qualifying Activities for Bristol SaaS in 2026:

  1. Building a New Technical Architecture: You’re moving from a monolithic system to a microservices architecture to handle scale, but you encounter data consistency issues that have no documented solution.

  2. Innovating with AI/ML: You’re training a machine learning model on a novel dataset where the outcome is uncertain, and you have to experiment with different training methods to reduce model drift or improve latency .

  3. Creating Advanced Algorithms: Your FinTech or PropTech SaaS requires a new type of algorithm for risk assessment or data visualisation that doesn’t exist “off the shelf.”

  4. Overcoming Hardware/Software Limits: You are developing IoT software that needs to process data at the edge with minimal power, requiring innovative coding to work within severe hardware constraints.

  5. Solving Data Processing Challenges: Your software needs to process and analyse massive datasets in real-time, but existing tools are too slow, requiring you to invent a new method.

❌ What DOES NOT Qualify (Even in 2026):

  • Routine Configuration: Setting up WordPress, Shopify, or standard CRMs for a client.

  • Commercial Activity: Market research, creating marketing funnels, or customer discovery (while vital for your business, it’s not R&D for tax purposes) .

  • Standard Problem-Solving: A coder simply fixing a bug using known methods.

  • Cosmetic Improvements: Changing the user interface (UI) for aesthetics rather than technological function .

A Local Warning: The Offshore Subcontractor Trap

Bristol is a global city, and it’s common for local SaaS founders to hire remote developers. Be very careful in 2026. Under the new merged scheme, the costs of subcontractors and externally provided workers (EPWs) based overseas are largely excluded from your R&D claim unless there are very specific, hard-to-meet circumstances .

If your R&D is truly happening in your office on Coldharbour Lane, but the code is being written by a team in a low-cost centre overseas, you may not be able to claim for those costs.

Preparing a claim now requires a detailed Additional Information Form (AIF) to be submitted before your tax return . This requires a technical narrative that proves your innovation.

Frequently Asked Questions (FAQs)

1️⃣ I run a SaaS startup in Bath. My project was difficult, but is that the same as "technologically uncertain"?

Not necessarily. For HMRC, “difficult” means a competent professional could eventually do it with enough time. “Uncertainty” means that at the outset, a competent professional couldn’t say for sure if it was possible or how to achieve it . If you were experimenting and didn’t know if the tech would work, you likely have a valid claim.

2️⃣ Can I include the cost of my cloud servers (AWS/Azure) in my R&D claim?

Yes, potentially. Under the 2026 rules, the cost of software, data licences, and cloud computing services directly consumed in the R&D project can be included as a qualifying cost .

3️⃣ My Bristol SaaS company is loss-making. Is there any point in claiming?

Absolutely. In fact, this is where R&D tax credits are most powerful. As a loss-making company, you can’t reduce your tax bill (you aren’t paying one), but under the ERIS rules (if you meet the intensity threshold) or the merged scheme, you can surrender those losses for a cash payment from HMRC . It’s non-dilutive funding for your growth.

4️⃣ How far back can I claim for my software development in Wiltshire?

Generally, you have two years from the end of your accounting period to make a claim . This means for the 2026 tax year, you can still amend claims for the previous two years if they are still open.

5️⃣ What is the Additional Information Form (AIF) and why is it important?

The AIF is a mandatory form introduced to improve compliance. It requires a detailed breakdown of your R&D projects, the uncertainties faced, and the costs incurred . Crucially, you must submit this form before you file your Corporation Tax return. If you don’t, your claim will be invalid .
