What are R&D tax credits?

R&D Tax Relief is a government scheme designed to encourage innovation and technological advancement in UK businesses. The scheme allows companies to reclaim some of their expenditure on qualifying research and development activities.

20% gross credit The merged scheme provides a gross RDEC of 20% on qualifying expenditure.
30% ERIS threshold Enhanced support is available for qualifying loss-making R&D intensive SMEs.
Two-year claim window R&D tax relief claims must generally be made within the relevant claim time limit.

How R&D tax relief works

The R&D tax credit scheme was introduced by the government in 2000. It allows companies to claim relief for expenditure incurred on qualifying research and development activities.

The scheme is open to businesses of all sizes and sectors, not just those in science or technology. Qualifying costs can include staff salaries, subcontractors, software, consumables and utilities.

Depending on the circumstances, companies may receive either a reduction in their Corporation Tax bill or a cash credit.

The merged R&D scheme For accounting periods beginning on or after 1 April 2024, the previous SME and RDEC schemes were replaced by the merged scheme for most companies.
Enhanced R&D Intensive Support A separate enhanced level of support remains available for qualifying loss-making R&D intensive SMEs.

Which R&D scheme applies?

Business professionals discussing a project

Small and medium-sized companies

For R&D tax purposes, an SME is defined as having fewer than 500 employees and either turnover not exceeding £100 million or gross assets not exceeding £86 million.

SMEs with less than 30% qualifying R&D spend claim under the merged scheme. A qualifying loss-making SME with R&D intensity of at least 30% may instead qualify for Enhanced R&D Intensive Support.

R&D intensive SMEs

Enhanced support of up to 27%

Loss-making SMEs meeting the 30% R&D intensity threshold can qualify for the enhanced intensive regime.

Large companies

Merged R&D scheme

Businesses with 500 or more employees, and either turnover above £100 million or gross assets above £86 million, fall within the merged scheme.

Enhanced R&D Intensive Support

Under ERIS, qualifying companies benefit from an additional 86% tax deduction on R&D expenditure and a higher 14.5% payable credit, resulting in a potential benefit of up to 27%.

30%

R&D intensity threshold

Qualifying R&D expenditure must represent at least 30% of relevant expenditure for the company to qualify.

86%

Additional deduction

The intensive regime provides an additional 86% tax deduction on qualifying R&D expenditure.

14.5%

Payable credit

The surrenderable loss is eligible for a higher 14.5% payable credit rate.

1 year

Grace period

A one-year grace period applies where a business temporarily falls below the 30% R&D intensity threshold.

The grace period helps provide greater stability where a qualifying company's R&D intensity fluctuates between accounting periods.

What counts as R&D for tax relief purposes?

A project must seek an advance in the overall knowledge or capability within a field of science or technology, rather than simply doing something that is new to the company.

The project must also involve scientific or technological uncertainty that could not readily be resolved by a competent professional working in the relevant field.

1

The advance must be in the wider field

HMRC looks at whether the project sought to improve the overall knowledge or capability available in the relevant field of science or technology, not simply the company's own knowledge.

2

There must be genuine technological uncertainty

The outcome, method or solution must not have been readily deducible by a competent professional using the knowledge and capability already available.

3

A project does not have to succeed

Eligibility is based on the advance the project sought. Work may still qualify where the intended advance was only partially achieved or ultimately unsuccessful.

Examples by sector

R&D activity can take many different forms depending on the field of science or technology involved.

R&D is not limited to laboratories

Qualifying work may involve engineering, manufacturing, software, medical technology and many other areas. What matters is whether the project meets the underlying conditions for R&D tax relief.

Engineering

Creating precision systems or components that outperform current capabilities.

Manufacturing

Improving production efficiency, reducing waste or developing materials with enhanced strength or resistance.

Biotech & medical

Creating new diagnostic methods, treatments or devices.

Software

Developing algorithms or platforms that solve performance, integration or scalability issues.

Qualifying R&D costs

Typical categories of qualifying expenditure include the following where the costs relate to qualifying R&D activity.

01

Staff costs

Staff costs including employer National Insurance contributions and pension contributions.

02

Externally provided workers

UK-based externally provided workers can qualify where the relevant conditions of the scheme are met.

03

Subcontractor costs

Certain subcontractor costs may qualify subject to the applicable R&D rules.

04

Consumables

Consumables and materials used in R&D, including light, heat, power and water where the conditions are met.

05

Software

Software directly used in qualifying R&D activities can form part of the claim.

06

Cloud computing & data

Relevant cloud computing and data costs can qualify where they are used directly for qualifying R&D.

How to claim R&D tax relief

A claim requires the qualifying projects and costs to be identified, documented and submitted to HMRC in the required form.

01

Notify HMRC where required

Submit an Advance Notification Form within six months of the accounting period end unless the exemption rules apply.

02

Identify qualifying projects

Identify work that meets HMRC's definition of R&D for tax purposes.

03

Gather qualifying costs

Identify expenditure falling within the relevant qualifying categories.

04

Prepare the technical narrative

Explain the technological uncertainties, the advance sought and the R&D undertaken.

05

Submit the Additional Information Form

The required Additional Information Form is submitted to HMRC online.

06

Include the figures in the CT600

The relevant R&D figures are included within the company's Corporation Tax Return.

07

Receive the benefit

Depending on the company's circumstances, the benefit may be received as a tax saving or cash credit.

Claim and Advance Notification deadlines

R&D tax relief claims must generally be made within two years of the end of the relevant accounting period. If a company is claiming for the first time, or does not meet the exemption based on previous claims, an Advance Notification Form may also be required within six months of the accounting period end.
