R&D Tax Credit Eligibility: What UK Businesses Can Claim

R&D tax credits are a valuable way for UK businesses to recover costs spent on innovation. However, not every project qualifies. Understanding who can claim and what counts as qualifying R&D is key to maximising your claim. This page explains eligibility criteria, qualifying activities, and the costs you can include in your R&D tax relief claim.

Who Can Claim R&D Tax Credits?

R&D tax credits are available to both SMEs and large companies, but the rules differ slightly:

SMEs (Small and Medium-sized Enterprises)
- Fewer than 500 employees and either turnover < €100m or balance sheet < €86m
- Can claim under the SME R&D tax relief scheme, receiving up to 33% of qualifying expenditure
Large Companies
- Can claim under the RDEC (Research and Development Expenditure Credit) scheme
- Usually receives a taxable credit of around 10–13% of qualifying expenditure

Sectors that frequently claim R&D tax relief:

Software and IT development
Engineering and manufacturing
Construction and infrastructure
FinTech and digital finance
Biotechnology and clinical research

What Counts as Qualifying R&D?

For tax purposes, R&D is not about patents or general improvements. HMRC defines qualifying R&D as projects that seek an advance in science or technology and involve uncertainty that competent professionals cannot solve easily.

Examples of Qualifying Activities

Software development: Integrating complex systems, creating new algorithms, or overcoming technical scalability or security challenges
Process improvement: Automating workflows or reducing production waste in manufacturing
Engineering innovation: Developing new materials, construction techniques, or tools to solve site-specific challenges
FinTech solutions: Building blockchain protocols, fraud detection algorithms, or other novel financial models
Clinical research: Automating analysis, testing prototypes, or developing medical devices

Key principle: If your project required trial-and-error or problem-solving beyond standard practices, it is likely to qualify.

Common Misconceptions About R&D

Many businesses assume that everyday improvements or minor tweaks count as R&D. This is not always true:

Routine engineering or coding does not qualify
Updating software for aesthetic purposes does not count
Projects must involve technological uncertainty
HMRC uses the “competent professional” test: a professional in your field should not be able to solve the problem without experimentation

Eligible Costs for R&D Tax Relief

Understanding which costs can be claimed is crucial. Here’s a clear breakdown:

Cost Type	What Qualifies	Notes
Staffing Costs	Salaries, National Insurance, pension contributions for staff directly engaged in R&D	Includes project managers and analysts if fully dedicated to R&D
Subcontractors	65% of payments to unconnected third parties	SME scheme only
Software Licences	Technical software, simulation tools, cloud computing time	Excludes general office software
Consumables	Materials transformed or consumed during R&D	Includes prototypes, chemicals, energy used in testing
Externally Provided Workers (EPWs)	Agency workers supervised by your staff	Can claim 100% of payments if directly involved
