R&D Tax Relief in the UK: A Simple Guide for Innovative Businesses
If your company is working on new or improved products, services, or processes, you may be eligible for Research and Development (R&D) tax relief – a valuable incentive that can save you thousands of pounds each year. But what exactly counts as R&D, and how do you know if your project qualifies? Let’s break it down.
What is R&D Tax Relief?
R&D tax relief is designed to support companies that work on innovative projects in science and technology. Only companies paying UK Corporation Tax can claim.
To qualify, your project must aim to advance knowledge or capability in a field of science or technology, not just improve your business processes.
What Counts as Science or Technology?
Science is the systematic study of the physical and material universe – from chemistry and biology to engineering and physics.
Technology is the practical application of scientific knowledge.
Since April 2023, mathematical advances can also count as science if they represent progress in understanding the physical or material universe.
An advance can be:
Physical – for example, a new cleaning product or a process that reduces waste.
Intellectual – such as new knowledge, methods, or improvements in capability.
What Qualifies as an Advance?
Your project must aim to create a genuine, appreciable improvement in science or technology. This could include:
Creating something new – a process, material, device, product, or service that increases knowledge or capability.
Improving something existing – not just minor tweaks, but significant upgrades that reduce costs, increase efficiency, or improve performance.
Replicating in a new way – using science or technology to achieve the same result as an existing product or process, but in an innovative or improved manner.
💡 Important: The advance must benefit the overall field, not just your company. Even if another business has made a similar advance, you may still qualify if it’s not publicly known.
What is Scientific or Technological Uncertainty?
R&D tax relief only applies when your project resolves scientific or technological uncertainty.
This means:
A competent professional cannot easily say if something is possible, or how to achieve it.
You need to be able to explain your approach, including any failures or trial-and-error, showing why the solution was not obvious.
Routine optimisations, copying existing solutions, or minor improvements do not count.
What Activities Qualify as R&D?
Direct activities that resolve scientific or technological uncertainty include:
Creating or adapting software, materials, or equipment for the project.
Scientific or technological planning, design, testing, and analysis.
Indirect activities can also qualify if they support R&D:
Staff training for the project.
Maintaining labs, equipment, or software.
Administrative and finance support directly linked to R&D.
Feasibility studies to guide specific R&D activities.
Activities unrelated to solving scientific or technological problems – such as marketing, sales, routine administration, or product distribution – do not count.
System Uncertainty
Sometimes uncertainty arises not from individual components but from the complexity of the system as a whole.
For example, you may know how each part of a device works, but it may still be unclear how to integrate them to achieve the desired function. Solving this is considered R&D.
Why Claiming R&D Relief Matters
R&D tax relief can reduce your Corporation Tax bill or even provide cash back if your business is loss-making. Many small and medium-sized enterprises are surprised at how much they qualify for – often thousands or tens of thousands of pounds.
Even if your project doesn’t fully succeed, if it involved resolving scientific or technological uncertainty, it still counts as R&D.
Key Takeaways
R&D must aim to advance knowledge or capability in science or technology.
Projects must resolve scientific or technological uncertainty.
Direct and certain indirect activities supporting the R&D can qualify.
