The Facebook Live for March 2026 raised awareness of a valuable but often misunderstood government incentive. It broke down what qualifies as Research and Development for SMEs (it’s broader than you think), explained the difference between the SME and RDEC schemes, and outlined the key information needed to prepare a claim with your bookkeeper or accountant. The information covered is for businesses that have an accounting period start date of before April 1st, 2024.
It’s Not Just for People in Lab Coats!
Many business owners hear the phrase “R&D tax credits” and immediately assume it only applies to laboratories, scientists in white coats, or large tech companies developing cutting-edge software.
In reality, that’s one of the biggest misconceptions surrounding the UK’s R&D tax relief scheme.
Thousands of small and medium-sized businesses across industries—from manufacturing and construction to food production and digital services—successfully claim R&D tax credits every year. If your business has invested time and resources into improving products, processes, or services, you may already be carrying out qualifying R&D without even realising it.
R&D tax credits are designed to encourage innovation across all sectors, not just high-tech industries.
You may qualify if your business has:
- Improved a product or service
- Developed a new manufacturing process
- Solved a technical challenge in production
- Built bespoke software to improve efficiency
- Experimented with new materials or techniques
For example:
- A construction company developing a new method to reduce structural load
- A food manufacturer experimenting with new recipes or preservation methods
- An engineering firm creating a more efficient component
- A software agency developing a custom platform for a client
If your team had to overcome technical uncertainty and couldn’t easily find the solution, there’s a good chance it could qualify as R&D.
What Actually Counts as R&D?
For tax purposes, R&D has a specific definition.
A project may qualify if it seeks to achieve an advance in science or technology by resolving scientific or technological uncertainty.
In simpler terms, your project may qualify if:
- You were trying to improve or create something
- The solution wasn’t readily available or obvious
- You had to experiment, test, or iterate to find a solution
Typical qualifying activities include:
- Designing and testing prototypes
- Developing or modifying software systems
- Engineering new components or machinery
- Experimenting with materials or formulations
- Improving production processes or automation
- Conducting technical testing or modelling
It’s important to note that commercial challenges alone don’t qualify. The uncertainty must be technical rather than financial or market-based.
How the SME R&D Tax Relief Scheme Works
The SME scheme is the most commonly used R&D tax relief programme in the UK.
To qualify as an SME, your business must typically have:
- less than 500 staff
- a turnover of under 100 million euros, or
- a balance sheet total under 86 million euros, and
- have an accounting period beginning before April 1st, 2024.
Don’t worry if your accounting period begins on or after April 1st, 2024; that doesn’t mean you cannot claim anything, it just means you could be eligible to claim under the Research and Development merged scheme (RDEC) or the Enhanced R&D intensive support (ERIS). The RDEC and ERIS schemes replace the SME scheme for businesses that have an accounting period that starts on or after April 1st, 2024. The qualifying expenditure rules for the two schemes are identical, but the calculation of the credit amount is different. I will be covering the scheme for claiming R&D tax credits for businesses with an accounting period after April 1st, 2024, in a future Facebook Live.
Under the scheme, businesses can claim an enhanced deduction on qualifying R&D costs, which reduces their corporation tax bill.
Depending on whether the company is profitable or loss-making, the benefit works slightly differently:
Profitable companies
- Receive additional tax relief that reduces their corporation tax liability.
Loss-making companies
- Can potentially surrender losses for a cash credit, providing a valuable cash injection for growing businesses.
For many SMEs, this can represent a significant return on the money invested in innovation.
However, when you are working out if you are eligible to claim R&D Tax Credits, if your business is linked to another business, you need to include those figures in your total. For example, your business is linked to another if it holds over 50% of the voting rights, and another business holds over 50% of the voting rights in your business. This is something I will cover in a future Facebook Live.
What Costs Can You Claim?
Another common misunderstanding is that only large equipment purchases qualify. In reality, a wide range of project costs can be included in an R&D claim.
Eligible costs often include:
Staff Costs
- Salaries and wages of employees involved in R&D
- Employer’s National Insurance contributions
- Pension contributions
Subcontractor Costs
- Payments to third-party contractors who worked on R&D activities
Software
- Software licences required for development or testing
Consumables
- Materials used during testing or prototyping
- Components used during development
Utilities
- Proportion of electricity, fuel, or water used for R&D activities
Externally Provided Workers
- Agency staff or specialists brought in to support development work
The key factor is that the costs must be directly related to qualifying R&D activities.
How to Start an R&D Tax Credit Claim
Starting a claim may sound complex, but the process is usually straightforward when broken down into a few steps. However, this is a specialist area, and the key is to document everything! What was the uncertainty? What did you do to try to solve it? What were the failures and successes? This information will be used to prepare the report that you will submit with your company tax return.
1. Identify Qualifying Projects
Review your projects over the last accounting period and identify those involving technical challenges or innovation.
2. Gather Financial Data
Compile the relevant costs associated with those projects, including staff time, materials, and subcontractor expenses.
3. Prepare the Technical Narrative
HMRC requires an explanation of:
- The scientific or technological advance sought
- The uncertainties faced
- How the team attempted to overcome them
4. Submit the Claim
R&D claims are typically submitted as part of your Corporation Tax return, supported by a technical report and cost breakdown.
5. Receive the Benefit
Once processed, HMRC will apply the tax reduction or issue a cash payment if applicable.
R&D tax credits are one of the UK’s most valuable incentives for innovative businesses, yet many companies fail to claim simply because they assume they don’t qualify. The reality is that innovation happens in businesses of all sizes and industries, not just in laboratories or global technology firms. If your business has spent time solving technical problems, improving processes, or developing new products, it may already qualify for R&D tax relief.
Taking the time to explore the scheme could unlock valuable tax savings or additional cash flow to reinvest in future innovation.
