What Types of R&D Activities Qualify for Tax Credits?

Research and Development (R&D) tax credits are one of the most valuable incentives available to UK businesses investing in innovation. They are designed to reward companies that are pushing the boundaries of science and technology by offering tax relief on qualifying R&D expenditure.

Despite the substantial financial benefits, many businesses remain unaware of what activities actually qualify for R&D tax credits. At ABM, we help companies navigate these rules to ensure maximum benefit. If you’re a business owner or finance manager in the UK, this guide will explain everything you need to know about qualifying R&D activities, including examples, eligibility, and claiming tips.

Understanding R&D Tax Credits

R&D tax credits are a government-backed incentive that allows companies to reduce their Corporation Tax liability or, for some SMEs, receive a cash payment. These credits are available to businesses across multiple sectors, including software development, manufacturing, healthcare, construction, and creative industries.

The main purpose of the scheme is to encourage innovation and scientific progress. Any project that seeks to make an advance in science or technology, while overcoming scientific or technological uncertainties, could be eligible.

Key benefits of R&D tax credits include:

• Reduction in Corporation Tax
• Cash payments for loss-making SMEs
• Funding to reinvest in future projects
• Incentives to develop new processes, products, or services

Who Can Claim R&D Tax Credits?

Before diving into the types of qualifying activities, it’s important to understand which companies can claim R&D tax credits.

Eligible Businesses:

• UK Limited Companies: Only companies liable for Corporation Tax are eligible. This includes private limited companies (Ltd) and public limited companies (PLC).
• Companies Limited by Guarantee: Not-for-profit companies that generate taxable profits may also claim.
• Group Companies: Corporate members of a group can claim for qualifying R&D activities carried out within the group structure.
• Loss-Making SMEs: Businesses with fewer than 500 employees, turnover under €100 million, or a balance sheet below €86 million can claim enhanced relief.

Businesses that cannot claim directly:

• Sole traders
• Most Limited Liability Partnerships (LLPs) unless a corporate member exists

What Counts as a Qualifying R&D Activity?

For R&D tax credits, not all innovation-related work qualifies. HMRC defines qualifying R&D activities as projects that:

1. Seek to make an advance in science or technology
2. Attempt to resolve scientific or technological uncertainty
3. Cannot be easily solved by a competent professional

A “competent professional” refers to someone with relevant expertise and experience in the field, who cannot immediately figure out the solution using known methods.

Types of Qualifying R&D Activities

R&D activities can be broadly divided into direct activities and indirect activities.

1. Direct R&D Activities

These are activities that directly contribute to resolving scientific or technological uncertainty. They include:

a) Creating New Products

Developing a completely new product that improves functionality, efficiency, or performance.
Example: A tech startup designing an AI-based software platform for medical diagnostics that incorporates new algorithms to improve accuracy.

b) Enhancing Existing Products or Processes

Making appreciable improvements to an existing product, process, or service. Minor tweaks do not count; the improvement must represent a meaningful advance.
Example: A manufacturing company redesigning its assembly line process to reduce waste and improve productivity using new machinery.

c) Developing New Software Solutions

Software development often qualifies as R&D if it addresses technical challenges or introduces innovative solutions.
Example: Custom software for automated data processing that solves scalability issues for large datasets.

d) Experimenting with Materials or Technology

Testing and trialing new materials, chemicals, or processes to determine functionality and performance.
Example: Using a new composite material in construction projects to improve durability and reduce carbon emissions.

e) Prototype Testing and Iteration

Prototyping, testing, and refining designs as part of the development process. This includes systematic trials, testing for failure points, and implementing improvements.
Example: Creating a series of prototypes for a new electric vehicle battery system to optimize performance and safety.

2. Indirect R&D Activities

Indirect activities support core R&D work but do not directly solve the technological uncertainty. HMRC allows some of these costs to be claimed if they are essential to the R&D project.

Examples include:

• Administrative Support: Staff involved in managing the R&D project, such as tracking expenses, managing contracts, or coordinating teams.
• HR Recruitment: Hiring skilled personnel required for R&D activities.
• Feasibility Studies: Conducting preliminary research to identify technological approaches or evaluate possible solutions.
• Training: Specialist training programs for R&D staff on new tools, software, or methodologies.
• University or Academic Collaborations: Work conducted in collaboration with universities, such as literature reviews or testing, that supports the core project.
• Equipment Maintenance: Maintaining machinery, labs, or servers dedicated to R&D work.

Example: A software company in London maintaining a dedicated AI lab and hiring PhD-level researchers to develop a machine-learning model. These activities may not directly solve the technical problem but qualify as indirect R&D costs.

Costs That Can Be Claimed

When claiming R&D tax credits, it’s not just activities that matter—eligible costs are crucial too.

Main categories include:

• Staff Costs: Salaries, employer’s National Insurance contributions, pensions, and reimbursed expenses of employees involved in R&D.
• Subcontractors and Freelancers: SMEs can claim some costs of subcontracted R&D work.
• Materials and Consumables: Items used or transformed during R&D, including prototypes, raw materials, and certain utilities like electricity, heat, and water.
• Software Licenses: Software directly used in the R&D process.
• Payments to Clinical Trial Participants: Relevant for healthcare and pharmaceutical R&D projects.

What Doesn’t Qualify for R&D Tax Credits?

Not all activities or costs are eligible. HMRC excludes:

• Routine maintenance or minor updates
• Commercial, administrative, or business-as-usual tasks
• Marketing, branding, or advertising costs
• Third-party work done without innovation
• Standard software implementation without technical challenges

Example: Updating an office network without developing new software or technology does not qualify.

Sector-Specific Examples of Qualifying R&D

To make this clearer, here are examples of qualifying R&D across industries:

Software & Technology

• Developing AI, machine learning, or blockchain solutions
• Creating bespoke software to solve complex internal problems

Creative & Digital Industries

• Animation, VFX, and video game development with technical innovation
• Digital platforms incorporating new interactive technology

Manufacturing & Engineering

• Developing new machinery or refining processes
• Using advanced materials to improve production efficiency

Healthcare & Life Sciences

• Pharmaceutical R&D, medical device development
• Diagnostic tools or new therapeutic processes

Construction & Architecture

• Smart building technologies
• Innovative methods to improve sustainability or reduce waste

The R&D Claim Process

Claiming R&D tax credits requires a structured process:

1. Check Eligibility – Confirm your company pays Corporation Tax and undertakes qualifying activities.
2. Identify Qualifying Activities & Costs – Document direct and indirect R&D activities, including expenditure.
3. Calculate Relief – Use HMRC’s guidance to calculate SME, Merged Scheme, or ERIS claims.
4. Prepare Technical Report – Outline the R&D project, technological challenges, and uncertainties.
5. Submit Claim via Company Tax Return – Include R&D claim in your CT600 return with all supporting documentation.
6. Keep Records – Maintain detailed evidence for at least six years in case of HMRC enquiry.

Tip: Many businesses partner with a professional London Accountant to ensure claims are accurate, maximize relief, and avoid HMRC queries.
