Technical correction to intensity ratio definition in Research and Development small or medium-sized enterprises rules

Published 30 October 2024

Who is likely to be affected

Small or medium-sized enterprises that have a high Research and Development (R&D) intensity (40% or above of their expenditure is on R&D) and claim the enhanced rate of small or medium-sized enterprise payable R&D tax credit for expenditure incurred from 1 April 2023 in an accounting period that began before 1 April 2024.

General description of the measure

This measure amends legislation in Schedule 1 to the Finance Act 2024 to include all relevant R&D expenditure incurred on or after 1 April 2023 in the calculation of the R&D intensity condition.

Policy objective

The change ensures that all companies that were originally intended to benefit from the enhanced relief will be able to do so.

Background to the measure

At Spring Budget 2023 the then Chancellor announced enhanced support for R&D intensive small or medium-sized enterprises, applying from 1 April 2023. The original details were set out in a technical note about additional tax relief for Research and Development intensive small and medium enterprise which stated that the relief would be available where R&D intensity, the ratio of qualifying R&D expenditure to total expenditure in a period, was 40% or more. Further changes were announced at Autumn Statement 2023.

Legislation was introduced in the Finance Act 2024. In this legislation, the R&D intensity calculation does not take account of any expenditure of the company for which it is entitled to Research and Development Expenditure Credit. It was always intended that this expenditure should be included.

Detailed proposal

Operative date

This measure will be retrospective and take effect from 1 April 2023.

Current law

Current law on the R&D tax relief rates for small or medium-sized enterprises is contained in Chapter 2 of Part 13 of Corporation Tax Act 2009.

Proposed revisions

Paragraph 21 of Schedule 1 to Finance Act 2024 will be amended so that subsection 7 of section 1045ZA of Corporation Tax Act 2009 is to be read as also including expenditure qualifying for Research and Development expenditure credit.
