What HMRC Means by an Advance in Science or Technology in AgriTech
HMRC relies on the BIS Guidelines on the Meaning of Research and Development for Tax Purposes to judge whether agritech work qualifies. The test is not novelty to your company. The work must seek an advance in science or technology overall, and the person doing it must face genuine uncertainty that a competent professional in the field could not readily resolve from published knowledge.
In agritech this means four things in practice. First, HMRC draws a hard line between systematic experimentation and commercial production. Growing crops under a known protocol, even in a novel facility, is not R&D. Designing the protocol and running controlled trials to determine whether it works is. Second, biology counts. The BIS Guidelines include the biological sciences, so genomics, plant pathology, soil microbiology, and animal physiology are all in scope where the work seeks a genuine scientific advance. Third, hardware and software attached to the biology counts too: novel sensors, machine learning models for crop health, autonomous field robots, and vertical-farm control systems are all mainstream qualifying categories. Fourth, scale-up from lab or pilot to commercial facility can itself constitute R&D where the technical route to scale was uncertain at the outset.
The SIC code for most agritech product companies is 72110 (Research and experimental development on biotechnology) or 62010/62020 (software). Farming businesses are SIC 01, and HMRC applies the same BIS test: systematic activity, advance, uncertainty. See our general agritech guide for more on how farm-led R&D is assessed.
What Qualifies as R&D in AgriTech
Vertical Farming and Controlled-Environment Agriculture
Vertical farming generates strong claims where the work moves beyond deploying existing equipment. Qualifying examples include: designing LED lighting spectra and duty cycles that maximise photosynthetic efficiency for a specific crop where published data did not resolve the optimum; developing novel nutrient-film or aeroponic delivery systems where pressure, pH cycling, and mineral ratios had to be experimentally determined; engineering energy-recovery airflow and thermal management systems for a specific building envelope; and building predictive microclimate models trained on sensor data where off-the-shelf HVAC control logic proved inadequate. Scaling from a 200-sqm R&D trial to a 5,000-sqm commercial installation often involves genuine engineering uncertainty about structural load, airflow dynamics, and electrical demand, all of which can qualify.
Agricultural Robotics and Autonomous Systems
Robotics and autonomous field vehicles are among the most active agritech claiming categories. Qualifying work includes: developing computer-vision systems for selective harvesting where existing models could not achieve the accuracy needed at the required speed; engineering end-effectors (grippers, cutters) for soft-fruit or brassica harvesting where the mechanical design required iterative experimental work; building machine-learning pipelines that classify crop disease or weed species in real field conditions rather than controlled lab images; and designing autonomous navigation systems for unstructured farm environments where standard industrial robot control architectures were insufficient.
Crop Genomics and Precision Breeding
Genomic selection programmes, CRISPR-based trait development (within UK regulatory scope), marker-assisted breeding for disease resistance or yield, and novel plant-phenotyping platforms all qualify routinely under the BIS Guidelines. The advance must be in the science itself. Applying a known genomic technique to a new variety does not automatically qualify; the qualifying work is where the technique's application to a specific trait involved genuine uncertainty about the methodology, the markers, or the expression outcomes.
Precision Agriculture and Digital Farm Platforms
Variable-rate application systems, drone-based multispectral imaging, soil-sensor networks, and the ML models that process their data are all claimable where the technical advance is real. HMRC's guidance at CIRD81900 is clear that software embedded in agricultural hardware is assessed on the same technological-uncertainty test as standalone software.
What Does NOT Qualify: AgriTech Anti-Patterns
These are the most common false positives HMRC challenges in agritech claims:
- Routine commercial growing. Operating a vertical farm, greenhouse, or precision-ag system under an established protocol is production, not R&D, even if the equipment is novel to the business.
- Purchasing and deploying standard equipment. Buying a known robotic harvester, drone, or irrigation system and operating it per the supplier's guidelines does not qualify. Modifying it to resolve a technical limitation might.
- Marketing trials and consumer preference testing. Taste panels, packaging research, and retail placement studies are not R&D under any definition HMRC accepts.
- Regulatory compliance work. Pesticide residue testing, food-safety certification, and phytosanitary compliance are not R&D unless the testing itself advances scientific knowledge about the substance or process.
- Variety registration without novel breeding science. Registering a variety through conventional selection without a scientific advance in the selection methodology does not qualify.
- Data collection that is not part of a systematic experiment. Installing sensors and recording data without a defined hypothesis and protocol to test is not qualifying R&D, even if the data is subsequently useful.
Qualifying Costs for AgriTech Under the Merged Scheme
The allowable cost categories under the merged scheme are the same for agritech as for any other sector, but the proportions differ. The main categories for agritech claims are:
Staffing costs. Salaries, employer NI, and employer pension for UK employees directly engaged in qualifying R&D, apportioned by time. In agritech this typically includes research scientists, plant biologists, hardware engineers, software engineers, and field agronomists running trials. It does not include growing staff, logistics, or sales.
Consumables. Materials consumed or transformed in qualifying R&D: seeds, plant material, growth media, chemicals, biological inputs, and prototype components. Commercial crops grown for sale are not consumables even if they were grown alongside an R&D trial. HMRC's CIRD84300 guidance requires a clear audit trail from the project to the materials issue records.
Subcontractors and EPWs. Under the merged scheme, subcontracted R&D costs are only claimable for work performed in the UK, subject to the 65% haircut. University research partners running trials on your behalf under a clear contract may qualify. Overseas field-trial partners generally do not.
Cloud and software costs. Data-processing compute for genomics pipelines, ML training runs, and phenotyping image analysis can all be claimable from April 2023 onwards, subject to direct use in qualifying R&D. See the qualifying expenditure guide for the full cost-category rules.
ERIS for AgriTech
The Enhanced R&D Intensive Support (ERIS) scheme pays a 27% credit rate rather than the standard 20%, and allows a cash repayment to loss-making companies rather than an offset against future tax. To qualify for ERIS in a given period, a company must be loss-making in that period and must have qualifying R&D expenditure of at least 30% of total expenditure. For early-stage agritech businesses, where engineering and science costs dominate and commercial revenue is still building, the 30% threshold is frequently met.
The practical value: a loss-making vertical-farming startup with £800,000 of qualifying R&D spend in a total-expenditure base of £2m (intensity = 40%) would generate an ERIS credit of £216,000. Under the standard merged scheme at 20% the credit would be £160,000. After corporation tax (nil for a loss-making company), most of the ERIS credit is payable in cash. HMRC pays ERIS credits within 40 working days of a complete CT600 submission in most cases.
Worked Example: A Vertical Farming SME
A UK vertical farming company, SIC 01130, has total expenditure of £2.6m for the year to 31 March 2026. The company is pre-revenue on its commercial facility and is loss-making. It employs 12 plant scientists, 6 hardware engineers, and 3 software engineers. A specialist review identifies the following qualifying expenditure:
- £640,000: salaries and associated costs for research staff at 70-100% R&D time apportionment.
- £90,000: growth media, LED prototype components, sensor hardware consumed in qualifying trials.
- £55,000: UK subcontract costs for a specialist university phenotyping unit (65% of £85k invoiced).
- £75,000: cloud compute for image classification training and genomics data processing.
Total qualifying spend: £860,000. R&D intensity: £860k / £2.6m = 33%. The company is loss-making and above the 30% ERIS threshold.
Credit under ERIS: £860,000 x 27% = £232,200, payable as cash. Under the standard merged scheme at 20% the credit would be £172,000. The ERIS route puts an additional £60,200 in cash back to the business.
HMRC Enquiry Risks in AgriTech
HMRC's compliance team has focused on agritech claims where commercial growing activity and R&D activity are intermingled on the same site and in the same accounts. Common enquiry triggers include: claims that include growing-staff time without clear delineation from trial-staff time; consumable claims where the same seed or plant stock appears in both the R&D project narrative and the sales figures; ERIS intensity calculations where total expenditure has been narrowed by excluding commercial production costs; and university subcontract costs that include teaching or consultancy rather than specific qualifying work. A good adviser will structure the technical narrative and cost apportionment to withstand those specific challenges.
