Did you know that agricultural companies can apply for research and development (R&D) tax relief? Our agricultural business specialists summarise everything you need to know about R&D within the industry, including who is eligible to claim tax credits.

What is R&D?

From a tax perspective, R&D is defined as a project that aims to advance overall knowledge or capability in the field of science or technology. The term ‘research and development’ also encompasses projects and activities that support the resolution of scientific or technological uncertainties.

It is a common misconception that R&D only applies to the invention of something new and tangible. R&D can also involve improving working practices, by implementing new systems and processes or revolutionising existing ones for more efficient operations.

Examples of R&D in the agriculture sector

There is a vast number of research and development opportunities within the agricultural sector. Many farmers and business owners in the sector are natural innovators, having spent much of their working lives adapting the way they work to meet the needs of a rapidly evolving industry.

You may find that there are existing processes and projects within your business that already qualify as R&D. Some examples of R&D in the agricultural industry include (but are not limited to):

  • Development of new machinery
  • Initiatives to maximise yield
  • Sustainability processes, such as a waste reduction and reusable products
  • Fertiliser development
  • Vertical farming advancements
  • Animal health and welfare initiatives
  • Feeding trials
  • Digital and precision farming technologies, such as drone-based monitoring and automated crop management systems

How does R&D tax relief work?

Introduced in 2000, R&D tax relief is a government scheme that aims to promote scientific and technologic innovation within the UK. It offers a financial incentive to innovators and pioneers in business across all industries and sectors through R&D tax credits that reduce corporation tax on qualifying expenditure.

You can claim R&D tax relief on any project that fits the specified criteria, even if the project in question was ultimately unsuccessful in achieving its objectives. The relief only applies to certain costs however, including materials used, staff on payroll and subcontractors. Cloud computing and data licences are also qualifying costs.

Most overseas subcontracted R&D is no longer eligible unless it would be wholly unreasonable to carry out the work in the UK.

HMRC now requires a detailed technical narrative explaining the scientific or technological uncertainties addressed by the project, and scrutiny of claims has increased.

The amount of tax credits you are eligible for depends on which of the two schemes your company falls under:

Small and medium sized enterprises (SME) R&D relief

You can claim SME R&D relief if your business has less than 500 staff, in addition to a turnover less than 100 million euros or a balance sheet total less than 86 million euros.

The current SME enhanced deduction rate is 86% for qualifying expenditure in addition to the standard 100% deduction, resulting in a 186% total deduction.

Loss-making SMEs that meet the definition of an ‘R&D intensive SME’ (where qualifying R&D expenditure is at least 30% of total expenditure) can claim a payable credit of 14.5%. A PAYE/NIC cap applies to the amount of payable credit a company can receive based on its PAYE and NIC liability.

Research and Development Expenditure Credit (RDEC) scheme

RDEC can be claimed by large companies working on R&D projects, as well as any SME or large company that has been subcontracted to carry out R&D work on behalf of a large company.

Any companies claiming grants must claim under the RDEC scheme rather than the SME scheme.

The current RDEC rate is 20% of qualifying R&D expenditure. For most companies, a new merged R&D scheme now applies for accounting periods beginning on or after 1st April 2024, following RDEC-style rules.

Who can apply for R&D tax relief?

Although businesses in any sector can claim R&D tax relief, you must be liable to pay corporation tax, and relief is consequently only available for limited companies. Unfortunately, farming partnerships are therefore not eligible to apply for R&D tax credits.

How to claim R&D tax credits

R&D tax relief is claimed via the company’s corporation tax return and the deadline for making a claim is 24 months after the end of the relevant accounting period. For first-time claimants or companies that have not made a claim in over three years, you must notify HMRC within six months of your accounting period end to maintain eligibility. More information on the R&D tax relief application process can be found on the HMRC website.

Applying for R&D tax credits can be lengthy and complicated process, therefore we would always recommend that you seek specialist advice and support if you believe you are eligible to claim.
