R&D Tax Credit for Biotech and Life Sciences

Last reviewed October 12, 2026

Biotech and life sciences companies are natural candidates for the R&D tax credit. Drug development, diagnostic testing, laboratory process optimization, and biological research frequently involve the kind of technological uncertainty and systematic experimentation that the credit rewards.

What qualifies

Biotech and life sciences R&D qualifies when it meets the four-part test. Most research conducted in this industry inherently involves biological or physical science and systematic experimentation — the two criteria that other industries sometimes struggle to demonstrate.

Common qualifying activities

Drug and therapeutic development

• Designing and synthesizing new compounds where biological activity is uncertain
• Developing drug delivery mechanisms (formulation, encapsulation, targeted delivery)
• Conducting preclinical studies to evaluate safety, efficacy, or pharmacokinetics
• Developing manufacturing processes for biological products where yield, purity, or stability outcomes are uncertain
• Scaling up from laboratory to pilot to commercial production where process parameters must be re-established

Diagnostics and medical devices

• Developing new assays or diagnostic tests where sensitivity, specificity, or reproducibility is uncertain
• Designing medical devices where performance, biocompatibility, or manufacturing feasibility requires experimentation
• Engineering point-of-care testing platforms where miniaturization or integration creates technical challenges
• Developing software for medical image analysis or diagnostic interpretation

Laboratory process development

• Optimizing extraction, purification, or separation processes where efficiency or yield is uncertain
• Developing cell culture methods, fermentation processes, or bioreactor conditions for new organisms or cell lines
• Creating new analytical methods where detection limits or accuracy must be established
• Automating laboratory workflows where integration of instruments and data systems presents technical challenges

Agricultural biotechnology

• Developing new crop varieties, biological pest controls, or soil amendments where efficacy is uncertain
• Engineering fermentation or extraction processes for agricultural biologicals
• Developing testing methods for agricultural product quality or safety

Bioinformatics and computational biology

• Developing algorithms for genomic analysis, protein structure prediction, or molecular modeling
• Building data pipelines for processing biological data at scale where performance is uncertain
• Creating computational tools for experiment design or result interpretation

What does not qualify

• Routine quality control testing using established protocols
• Clinical trials conducted purely for regulatory compliance with no technical uncertainty about method
• Manufacturing existing products using established processes
• Literature reviews and data compilation without experimentation
• Market research or business planning for new products

Qualifying expenses

Biotech companies typically generate significant QREs across all categories:

• Wages — scientists, engineers, lab technicians, and bioinformaticians performing or supporting qualifying research
• Supplies — reagents, chemicals, biological materials, lab consumables, and prototype components consumed in R&D
• Contract research — CRO services, outside laboratory testing, and contract manufacturing development performed on your behalf

Supply costs can be substantial in this industry, making thorough tracking particularly valuable.

Frequently asked questions

Do biotech companies qualify for the R&D tax credit?

Yes. Biotech companies are among the strongest candidates for the R&D credit. Drug development, assay design, process development for biologics, clinical trial design, and analytical method development typically involve substantial technological uncertainty.

Can pre-revenue biotech companies claim the credit?

Yes. Pre-revenue biotech companies with fewer than 5 years of gross receipts and under $5 million in annual revenue can elect to apply up to $500,000 of the R&D credit per year against payroll taxes instead of income taxes.

Do clinical trial costs qualify for the R&D credit?

Portions of clinical trial costs can qualify. Employee wages for scientists designing and overseeing trials, supplies consumed in laboratory work, and contract research payments to CROs performing qualifying work may be included as QREs.
