Innovation is at the core of any successful business. It enables businesses to evolve and adapt to ever-changing markets, regulations, and the sector in which they are operating within. But pursuing cutting-edge projects can come with substantial cost and risk. Research and development (R&D) tax credits (formerly R&D tax relief) can remedy this issue, accessing vital funding and getting cash back into a business. 

Whether you’re a tech start-up, an established manufacturing company, or sit within the construction field, this guide explains how businesses can utilise the R&D tax credit scheme to advance their goals and secure non-dilutive funding. We’ll break down how the scheme works, outline eligible projects and cost categories, explain the relevant tax legislation and application process, and outline the importance of using a specialist provider.

What is R&D tax relief?

R&D tax relief was launched in 2000 by the UK government and is administered by HMRC. The scheme is intended to encourage and incentivise innovation and reward companies that invest in R&D related projects to drive economic growth within the UK. 

In essence, a business that participates in innovative projects can be provided with tax relief to encourage further investment in innovation. To give an indication of numbers, in the most recent statistics HMRC provided they shared that an estimated total of £7.6 billion of R&D tax relief was claimed in the tax year 2023-2024.

How do R&D tax credits work?

R&D tax credits allow businesses to reclaim a percentage of qualifying R&D expenditure either as a reduction in corporation tax liability or as a payable cash credit, depending on the company’s financial position and the scheme applied.

To make a claim, businesses must identify qualifying R&D projects and calculate the associated eligible expenditure. A claim is then submitted to HMRC as part of the company’s corporation tax return, alongside supporting technical and financial documentation explaining how the project meets HMRC’s criteria.

The amount a business can claim depends on:

  • The R&D scheme the business qualifies for
  • Whether the company is profit-making or loss-making
  • The value of qualifying expenditure incurred during the accounting period

Once processed by HMRC, the benefit is typically received either through reduced corporation tax, a cash repayment, or a combination of both.

R&D meaning and the activities that qualify for R&D tax credits

R&D has a specific meaning when it comes to tax purposes. HMRC’s definition can be broken down into three distinct criteria:

  1. Firstly, the activity has to have achieved or be seeking to achieve a scientific or technological advancement. This means that in carrying out the R&D, the business is advancing beyond the baseline for science or technology, within their field.
  2. Secondly, the activities must involve a degree of scientific or technological uncertainty. This assesses the difficulty of the project and any challenges that have been encountered in the project, and how the uncertainties have been overcome. Within this, the project’s uncertainties are considered in relation to its R&D, and the journey undertaken to resolve these uncertainties is evaluated regarding whether the solution was readily deducible to a competent professional in the field.  
  3. The final criteria that must be satisfied is ensuring that the company follows a systematic and logical process. Here it must be ascertained that a full development process was followed which was carefully thought out and pre-planned.  

Alongside the technical criteria, eligibility also depends on factors including if the company has submitted a Claim Notification Form (CNF)pre-informing HMRC of their intent to claim.

Which businesses qualify for R&D tax credits?

Any UK business that’s liable for corporation tax and whose project satisfies the above R&D criteria could be eligible for R&D tax credits. 

That said, although R&D can happen in any business, the advance must be in the field of science or technology in order to qualify for R&D tax relief. R&D tax credits are industry agnostic but, as expected, a lot of R&D activity sits within sectors including manufacturing, technology, and defence

HMRC also has guidance on what cannot be claimed, and explicitly states that advances cannot be claimed in the fields of arts, humanities and social sciences. If you’re unsure whether your business’s project qualifies, contact a member of our team.

What costs qualify for R&D tax credits?

There are five main categories of costs that are eligible for R&D tax relief, provided the costs relate directly to eligible R&D activities:  

  1. Staffing costs: gross salaries, employers’ pension payments, and employers’ National Insurance.
  2. Consumables: any resources that have been consumed, transformed, or destroyed in R&D processes, such as raw materials, utility expenses and prototype costs.
  3. Software: includes the purchase and maintenance costs of any software used in R&D activities. This also includes expenditure on data purchases and cloud computing from 1st April 2024.
  4. Sub-contracting/outsourcing: costs associated with the hire of external contractors undertaking R&D activities.
  5. Externally Provided Workers (EPWs): agency workers hired through intermediaries that contribute to resolving uncertainties within qualifying projects.
  6. Clinical trial payments: This is of interest to those within the life sciences sector.

Which R&D incentive are you eligible for?

There have been significant changes in the different incentives and rates of relief over the early 2020s. Previously, claims were made through two main schemes: Small and medium-sized enterprises (SMEs) and Research and Development Expenditure Credit(RDEC). But as of 1st April, these schemes merged into the R&D Merged Scheme. The main difference is primarily for SMEs and the rates they can claim. Outlined below are the different schemes currently in operation, and how much relief your business could be eligible to receive.

R&D Merged Scheme: combination of SME R&D Tax Relief & RDEC Schemes

This is essentially a continuation of the old RDEC Scheme. Any business that qualifies for R&D credits can claim up to a limit of 15% on qualifying costs. This applies to large businesses, profit-making SMEs and loss-making SMEs who don’t meet other ERIS scheme criteria (outlined below). The merged scheme enables the addition of claiming subcontracting costs which the RDEC did not previously allow.  

 

Enhanced R&D Intensive Scheme (ERIS)

If you’re a loss-making SME that meets the R&D intensity threshold, you may qualify to claim under the ERIS scheme. Businesses meeting this criteria can claim up to 27% on qualifying R&D costs. This enhanced relief can provide significant support for smaller R&D rich businesses, making it important to work with an advisor who can help determine the most appropriate scheme to claim under.  

How does HMRC’s R&D tax credits claims process work?

Here at RCK Partners we believe process is protection which is why we have devised a robust, compliance-led, claim preparation and submission process. See below for a summarised version of the process and how businesses needs to prepare a claim to be ready for review:

  • Initial claim preparation: gather detailed explanations of the project, how it qualifies as R&D, qualifying expenditure and evidence. At RCK, this stage is subject to an independent internal compliance review by a separate team led by former HMRC R&D inspectors.
  • Additional Information Form (AIF) submission: A mandatory submission which builds upon the underlying claim analysis. It requires a clear articulation of the scientific or technological uncertainties, activities undertaken and cost breakdowns, and is a key driver of HMRC’s initial risk assessment. RCK compile, draft, review and submit this form on the company's behalf during the R&D claim process.
  • Corporation tax return submission: the business files their CT600 which includes the R&D tax credit claim.
  • HMRC validates requirements: is there an AIF and was a pre-notification required? The pre-notification window varies based on the company year end and claim history with various exemptions. RCK can help align these dates and assess the requirement for a prenotification and if applicable file this ahead of the deadline on the company's behalf.
  • HMRC risk assessment and claim filtering: an internal risk assessment of the claim, including sector risk, quality of the submission. .
