R&D Tax Credits for Biotechnology Companies

Biotechnology companies use biological systems to develop new products, processes, diagnostics and production methods. Scientific uncertainty is central to much of this work, from assay and strain development to fermentation, bioinformatics, protein engineering and scale-up.

Innovation in biotechnology

Biotechnology businesses solve technical problems every day.

Biotechnology R&D is evidence-led and iterative. Biological variability, incomplete knowledge and scale effects mean competent professionals often need to design experiments and refine methods before a reliable outcome is possible.

This includes work across:

  • Assay development
  • Genetic engineering
  • Bioprocess development
  • Diagnostics
  • Fermentation
  • Bioinformatics
  • Protein engineering
  • Cell culture
  • Biomaterials
  • Process scale-up
  • Stability and storage
  • Environmental biotechnology

Qualifying R&D may arise where a business is not simply applying known methods, but is testing, adapting or developing a new approach because the scientific or technological answer is uncertain.

Qualifying R&D

How biotechnology businesses can qualify for R&D Tax Credits.

Qualifying R&D can arise where a project seeks an advance in science or technology and competent professionals must carry out systematic work to resolve genuine technical uncertainty.

  • Developing assays and diagnostics Projects may qualify where teams must resolve uncertainty in sensitivity, selectivity, repeatability or sample behaviour.
  • Engineering biological systems R&D may arise in strain, cell, gene or protein development where biological response cannot be readily predicted.
  • Improving fermentation and bioprocesses Optimising yield, viability, contamination control or downstream processing can involve qualifying uncertainty.
  • Creating bioinformatics methods New algorithms and data workflows may qualify where standard tools cannot answer the scientific or technical problem.
  • Developing biomaterials and formulations Testing stability, compatibility and function can require systematic scientific investigation.
  • Scaling laboratory work into production Scale-up may introduce new uncertainty in mixing, transfer, control, recovery and reproducibility.

A note from Dr Jack Brent

Biotechnology R&D claims need clear technical evidence.

Biotechnology projects can look like routine commercial delivery from the outside, even when the team has worked through difficult scientific or technological uncertainty. A defensible claim must identify the advance sought, the available baseline and why a competent professional could not readily determine the solution.

InnoFund separates ordinary delivery from the qualifying work and connects the technical narrative to contemporaneous evidence and eligible expenditure. That produces a focused claim that can withstand HMRC scrutiny.

Client experience

Biotechnology Companies Recommend InnoFund

Practical support from a multidisciplinary team that understands both the technical work and the claim.

“Would highly recommend, they know their stuff! They assisted greatly with an R&D claim rejection by HMRC.”

Steven Potts

Finance Director, Sigma Polymers

“Excellent from start to finish, lovely team and a great result. Highly recommended.”

Sam Collins

General Manager, Terra Farmer

Clear boundaries

Not every biotechnology project qualifies.

Commercial value, novelty or project difficulty do not qualify a project on their own. Examples of work that may fall outside the scheme include:

  • Routine delivery using established methods
  • Standard installation or configuration
  • Ordinary maintenance and repair
  • Commercial or cosmetic changes
  • Routine quality control
  • Straightforward replication of an existing solution
  • General project management
  • Work completed after technical uncertainty was resolved

Many projects contain a mixture of qualifying and non-qualifying activity. InnoFund identifies the technical boundary so the claim remains accurate and proportionate.

Eligible expenditure

Eligible R&D costs for biotechnology businesses.

Costs directly connected to qualifying activity may include:

  • Staff time spent on qualifying R&D
  • Employer National Insurance and pension contributions
  • Subcontracted R&D, where eligible
  • Externally provided workers
  • Software, cloud computing and data costs used for R&D
  • Materials and consumables used in trials
  • Prototype components and testing costs
  • Technical consultancy, where eligible

We trace expenditure back to the qualifying work and apply the rules relevant to the company, contract and accounting period.

Evidence & scrutiny

HMRC risk areas for biotechnology R&D claims.

A strong claim explains the science or technology rather than relying on broad statements about innovation. Common risk areas include:

  • Claiming commercial complexity rather than technical uncertainty
  • No clear baseline of existing science or technology
  • Routine work presented as R&D
  • Weak records of trials, failures and iteration
  • Incorrect treatment of subcontracted or customer-funded work
  • No competent professional input
  • Overclaiming whole projects instead of qualifying activity
  • Unclear project and cost boundaries

InnoFund reviews both the technical position and the expenditure so each claim is clear, evidence-led and defensible.

Assess your project

Questions, answered

Clear, practical answers to the questions businesses ask most often.

Yes. Biotechnology businesses can claim where a project seeks an advance in science or technology and competent professionals must resolve genuine technical uncertainty through systematic work.

Qualifying work may include Assay development, Genetic engineering, Bioprocess development, Diagnostics, Fermentation, Bioinformatics. Eligibility depends on the technical advance sought and the uncertainty encountered, not simply the commercial value of the project.

They can. A project does not have to succeed, and prototypes or failed trials can provide strong evidence that the outcome was not readily deducible at the outset. The work must still form part of a systematic attempt to resolve technical uncertainty.

Yes, where the business has to develop or materially adapt technology rather than simply buy, configure or use an established solution. The claim should explain the performance gap, technical uncertainty and work undertaken to resolve it.

Eligible expenditure may include qualifying staff costs, employer contributions, software, cloud and data costs, consumables, prototype materials, externally provided workers and some subcontracted R&D. The exact treatment depends on the accounting period and scheme rules.

Useful evidence includes design records, test results, trial data, technical notes, project plans, calculations, software logs, photographs, failure records, meeting notes, cost records and explanations from the competent professionals who led the work.
