R&D Tax Credits for Chemical Companies

Chemical companies are often at the centre of technical innovation, developing new formulations, materials, coatings, compounds, processes and production methods that must perform reliably, safely and commercially. Where your business is improving chemical performance, scaling up production, reducing environmental impact or overcoming uncertainty in formulation, synthesis, testing or manufacturing, you may be carrying out qualifying R&D. InnoFund helps chemical companies identify eligible activity, prepare compliant R&D Tax Credit claims and protect future innovation funding opportunities.

Sector innovation

Innovation in Chemicals

Innovation in the chemical sector often involves experimentation, testing and iteration across formulation, synthesis, materials behaviour, process control, stability, safety, compliance and scale-up. Qualifying R&D may arise where a business is developing or improving products, materials or processes because existing solutions cannot meet the required performance, cost, safety, environmental or production standards.

This includes work across:

  • Chemical formulation
  • Materials chemistry
  • Process development
  • Scale-up challenges
  • Polymers and composites
  • Coatings and adhesives
  • Battery materials
  • Sustainable chemistry
  • Waste reduction
  • Stability testing
  • Manufacturing optimisation
  • Product performance testing

Chemical R&D is often found in the detail: formulation records, lab tests, batch behaviour, process changes, scale-up issues, material properties and the iterations needed to reach a reliable technical outcome.

Qualifying R&D

How Chemical Companies Can Qualify for R&D Tax Credits

Chemical companies may qualify for R&D Tax Credits where they are seeking an advance in science or technology and have to overcome technical uncertainty. Qualifying activity can arise across formulations, materials, processes, scale-up, stability testing, sustainability and production methods.

  • Developing New Chemical Formulations R&D may arise where a business is developing new formulations or improving existing products to achieve specific performance, safety, stability, durability or environmental outcomes. This could include work on coatings, adhesives, cleaning products, polymers, additives, lubricants, treatments, compounds or specialist chemical products where the final result could not be predicted from existing knowledge.
  • Improving Chemical Processes and Production Methods Chemical companies may qualify where they are developing new or improved production methods to increase yield, reduce waste, improve consistency, lower energy use or overcome process limitations. R&D may sit in the uncertainty around reaction conditions, purity, temperature, pressure, mixing, separation, drying, curing, contamination control or production repeatability.
  • Scaling Up from Lab to Production Moving from laboratory-scale success to pilot or full-scale manufacturing can involve significant technical uncertainty. A formulation or process that works in small quantities may behave differently when scaled, creating challenges around consistency, safety, efficiency, cost, equipment suitability, batch quality or process control.
  • Sustainable and Green Chemistry R&D can arise where a business is developing lower-impact alternatives to existing chemicals, reducing hazardous substances, improving recyclability, replacing restricted ingredients or lowering emissions and waste. The qualifying activity must involve technical uncertainty, such as testing new inputs, reformulating products or changing processes while maintaining performance.
  • Advanced Materials, Polymers and Composites Chemical R&D may include developing or improving materials with specific properties such as strength, flexibility, conductivity, thermal resistance, chemical resistance, biodegradability, adhesion or barrier performance. This can be relevant to polymers, composites, 2D materials, battery materials, coatings, films, fibres and specialist industrial materials.
  • Testing, Stability and Product Performance Projects may qualify where a business has to carry out systematic testing to resolve uncertainty around shelf life, degradation, compatibility, performance under stress, safety, regulatory requirements or real-world operating conditions. Routine quality control is unlikely to qualify, but testing that informs technical development may be eligible.

A note from Dr Jack Brent

Chemical R&D Claims Need Scientific Precision and Strong Evidence

Chemical R&D claims need to be grounded in the science behind the project. A business may be improving a formulation, developing a new material, changing a production process or reducing environmental impact, but HMRC will want to understand the specific scientific or technological uncertainty involved.

That uncertainty might sit in chemical stability, reactivity, purity, yield, compatibility, material performance, production scale-up, safety, degradation, environmental impact or the interaction between ingredients, processes and end-use conditions. A strong claim needs to explain what was not readily deducible at the start of the project, what testing was carried out, what failed, what changed and how the business moved towards a workable solution.

Dr Jack Brent, InnoFund's Senior R&D Tax Manager, brings a rare combination of chemistry, materials science and R&D tax expertise. With a PhD in Materials Science, an MChem in Chemistry and research experience across graphene, phosphorene, composites, nanomaterials, battery technology and solar energy harvesting, Jack helps chemical businesses present their R&D in a way that is technically accurate, commercially relevant and compliant.

Clear boundaries

Not Every Chemical Project Qualifies for R&D Tax Credits.

Not every chemical formulation, product update or production issue will qualify for R&D Tax Credits. The key question is whether the business faced scientific or technological uncertainty and carried out systematic work to resolve it.

Examples of work that may not qualify include:

  • Routine quality control
  • Standard batch production
  • Basic formulation tweaks
  • Cosmetic product changes
  • Routine compliance testing
  • Standard ingredient substitution
  • Normal manufacturing optimisation
  • Off-the-shelf process changes
  • Commercial product launches
  • General market research
  • Routine troubleshooting
  • Work after uncertainty is resolved

Chemical projects often contain a mixture of qualifying and non-qualifying activity. InnoFund helps separate routine production from genuine R&D so the claim is accurate, compliant and defensible.

Eligible expenditure

Eligible R&D Costs for Chemical Businesses

Chemical businesses may be able to claim relief on qualifying costs linked to eligible R&D projects, including:

  • Chemist and scientist staff time
  • Process engineer staff time
  • Technical director time
  • Employer NIC and pension costs
  • Subcontracted R&D, where eligible
  • Externally provided workers
  • Software used for modelling or testing
  • Cloud computing and data costs
  • Materials used in trials
  • Prototype formulation costs
  • Consumables used in R&D
  • Testing and analysis costs

The treatment of trial materials, consumables, subcontracted work, testing, externally provided workers and technical consultancy can be particularly important in chemical R&D claims.

InnoFund helps identify which costs are eligible and ensures the claim is built around the qualifying scientific and technical work, not just the wider commercial project.

Evidence & scrutiny

HMRC Risk Areas for Chemical R&D Claims

HMRC is applying greater scrutiny to R&D Tax Credit claims, including claims from chemical, manufacturing and materials businesses. A strong claim must explain the scientific uncertainty clearly and show why the work went beyond routine production, quality control or commercial reformulation.

Common risk areas include:

  • Routine production claimed as R&D
  • Weak scientific uncertainty explanation
  • No clear technical baseline
  • Overclaiming quality control
  • Claiming cosmetic reformulation only
  • Poor records of failed trials
  • Incorrect subcontractor treatment
  • Not separating commercial and technical work
  • No competent professional input
  • Generic sustainability claims
  • Unclear project boundaries
  • Poor evidence of testing and iteration

InnoFund helps chemical companies prepare claims that are clear, compliant and evidence-led. We focus on the scientific work behind the project, the uncertainty faced, the process followed and the costs directly connected to qualifying activity.

Assess your project

Questions, answered

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

Yes. Chemical companies can claim R&D Tax Credits where they are seeking an advance in science or technology and have to overcome technical uncertainty. This may include work involving formulations, materials, production processes, scale-up, stability, testing, sustainability, coatings, polymers, composites or specialist chemical products.

Chemical formulation work may qualify where the business is trying to achieve a technical outcome that cannot be readily solved using existing knowledge. This could involve uncertainty around stability, performance, compatibility, safety, durability, environmental impact or how ingredients behave together.

Yes, process improvement can qualify where the business is developing a new or improved method and faces technical uncertainty. For example, improving yield, reducing waste, lowering energy use, improving purity or scaling production may qualify if the solution was not obvious at the start.

Yes. A project does not need to succeed to qualify. Failed formulations, unsuccessful production trials, rejected prototypes and abandoned technical approaches can still support an R&D claim if they were part of systematic work to resolve scientific or technological uncertainty.

Testing and analysis may be eligible where they are directly linked to qualifying R&D activity. Routine quality control or standard compliance testing is unlikely to qualify on its own, but testing used to resolve uncertainty, validate prototypes or guide technical development may be included.

Useful evidence may include formulation records, lab notes, batch records, test results, failed trial data, stability reports, materials analysis, process logs, scale-up records, safety reviews, supplier correspondence, technical meeting notes and explanations from the scientists or engineers involved.
