Last reviewed: 13 October 2026Life sciences businesses are often at the forefront of innovation, whether they’re developing new treatments, improving diagnostic technologies or designing more effective medical devices. However, many companies don’t realise that some of this work could qualify for R&D tax relief.
The challenge is that HMRC’s definition of research and development for tax purposes is often different from how businesses use the term in everyday conversation. An activity does not need to involve groundbreaking scientific discoveries to qualify, but it must seek to overcome genuine scientific or technological uncertainty.
Understanding what qualifies can help life sciences companies identify valuable tax relief opportunities while ensuring claims remain robust and compliant.
Does My Life Sciences Project Qualify for R&D Tax Relief?
A project may qualify for R&D tax relief if it aims to achieve an advance in science or technology and involves overcoming scientific or technological uncertainties that could not easily be resolved by a competent professional in the field.
In the life sciences sector, qualifying activities often include:
- Biotechnology research and development
- Drug discovery and formulation development
- Clinical development activities
- Medical device innovation
- Diagnostic technology development
- Laboratory process innovation
- Healthcare software development
- Improvements to scientific manufacturing processes
Not all innovative work qualifies. Commercial, marketing and routine business improvements generally fall outside HMRC’s definition of R&D.
HMRC’s Definition of R&D
For tax purposes, HMRC focuses on whether a project seeks an advance in science or technology.
To qualify, a business must generally demonstrate:
- A scientific or technological objective
- Technical uncertainty at the start of the project
- Work undertaken to resolve that uncertainty
- A genuine advance beyond existing knowledge or capability
The uncertainty must be more than a commercial challenge or budget constraint. The project should involve solving a problem where the answer was not readily available to competent professionals working in the field.
Common Life Sciences Activities That May Qualify
Biotechnology Projects
Biotechnology businesses frequently encounter scientific uncertainties when developing new biological processes, therapies or products.
Examples may include:
- Developing novel cell therapies
- Engineering biological systems
- Improving gene editing techniques
- Creating new production methods for biological products
The key factor is whether the work required overcoming scientific challenges rather than simply applying existing knowledge.
Drug Development and Pharmaceuticals
Pharmaceutical companies often undertake qualifying R&D while:
- Developing new drugs
- Improving formulations
- Enhancing drug delivery mechanisms
- Reducing side effects
- Improving manufacturing processes
Even where a project is ultimately unsuccessful, the work may still qualify if genuine scientific uncertainty existed.
Medical Devices
Many medical device companies undertake eligible R&D when attempting to improve:
- Product performance
- Safety outcomes
- Reliability
- Manufacturing techniques
- Regulatory compliance through technological innovation
Prototype development and iterative testing may form part of qualifying activities where technical uncertainties need to be resolved.
Diagnostics and Healthcare Technology
The development of diagnostic technologies often involves significant scientific and technological challenges.
Examples include:
- New testing methods
- Diagnostic platforms
- Digital health technologies
- AI-driven healthcare tools
- Clinical data analysis systems
Where technical obstacles must be overcome to achieve the desired outcome, some or all of the project may qualify.
Healthcare Software and Digital Innovation
Life sciences innovation increasingly relies on software development.
Software projects may qualify where teams are attempting to:
- Improve system performance
- Process complex scientific data
- Develop new algorithms
- Integrate advanced technologies
- Achieve functionality not readily achievable using existing solutions
Simply developing a business application or implementing off-the-shelf software would not usually qualify.
What Does Not Normally Qualify?
A common misconception is that all scientific work qualifies for R&D tax relief.
Activities that would not usually qualify include:
- Routine data collection
- Marketing activities
- Commercial decision-making
- Market research
- Regulatory submissions alone
- Standard quality control processes
- Adopting existing technologies without significant technical challenges
Each project should be assessed on its individual circumstances.
Claiming R&D Tax Relief
Businesses considering a claim should ensure they maintain appropriate records throughout the project.
Useful evidence may include:
- Project plans
- Technical reports
- Testing results
- Meeting notes
- Staff time records
- Cost documentation
Recent changes to the R&D regime have also increased compliance requirements, including the use of an Additional Information Form and, in some situations, a Claim Notification Form.
As HMRC scrutiny of claims continues to increase, clear documentation is becoming increasingly important.
How Life Sciences Businesses Can Strengthen Their Position
Before making a claim, businesses should consider:
- Whether genuine scientific or technological uncertainty existed
- When those uncertainties arose and were resolved
- Which staff were involved in overcoming them
- What qualifying expenditure was incurred
- Whether sufficient technical evidence exists
Taking a structured approach can help ensure claims accurately reflect the work undertaken and withstand potential HMRC review.
FAQs
No. Some activities associated with clinical development may qualify, but eligibility depends on whether scientific or technological uncertainties are being resolved.
Yes. A project does not need to succeed to qualify. What matters is whether genuine scientific or technological uncertainty existed and work was undertaken to resolve it.
It can. Activities such as drug development, formulation improvement and certain manufacturing innovations may qualify where technical challenges are present.
Potentially. Software development may qualify if it involves overcoming technological uncertainties rather than simply creating standard business applications.
