The new merged R&D tax relief scheme - what you need to know

2023’s Autumn Statement delivered by the Chancellor Jeremy Hunt, confirmed that the two R&D tax credit schemes (SME and RDEC) will be combined to form a new merged R&D scheme. This merged scheme R&D expenditure credit will apply to accounting periods beginning on or after 1 April 2024 and will not discriminate based on the size of the business, both SMEs and large businesses will claim under the same scheme and at the same above-the-line credit rate of 20%.

The HMRC guidance for the merged scheme will impact companies in different ways. To find out how it might effect your business, contact us.

What qualifies as an R&D project under the merged scheme?

The merged scheme continues with largely the same assessment criteria, to have a qualifying R&D project the project must satisfy three conditions:

  1. The project must have achieved, or is seeking to achieve, an advance in the overall knowledge or capability of a field of science and technology.
  2. There must have been a scientific or technological uncertainty.
  3. It must not be readily deducible to a competent professional working in the field to carry out the work.

New merged scheme R&D tax relief rate

As explained above, the merged scheme follows the RDEC payment model of an above-the-line expenditure credit at a rate of 20% for most businesses. However, the UK Government wants to reward the most R&D intensive businesses and incentivise those on the cusp of being R&D intensive to reach that threshold. Therefore, there is a second ‘scheme’ or ‘rate’ for loss-making R&D intensive businesses, called the Enhanced R&D Intensive Support (ERIS) scheme, that follows the previous SME calculation at a 14.5% rate. The threshold to meet the R&D intensity condition is at least 30% of a company’s total expenditure to be related to R&D.

How the effective R&D tax relief rates will impact your business

Rules of subsidisation under the new merged RDEC scheme

The previous SME scheme penalised businesses that received a form of subsidisation to offset the costs of their R&D project(s), perhaps in the form of grants or other funding. This limitation will be removed from the merged scheme, businesses with subsidised R&D projects will be able the full amount entitled to them should they meet the existing rules of the scheme.

Overseas restrictions under the new merged RDEC scheme

2021’s Autumn Budget saw Rishi Sunak announce the UK’s R&D reliefs will be focused to limit benefit to R&D done in the UK. This will be in force as part of the new merged RDEC scheme. Therefore, as a rule of thumb, overseas R&D costs will not be qualifying R&D expenditure under the merged scheme. However, there are exclusions to this rule, detailed here Overseas restrictions under the new merged RDEC scheme.

Contracted out R&D rules under the new merged RDEC scheme (subcontractor rules)

In November 2023, HM Treasury set out a technical note clarifying that in the merged scheme rules, the entity contracting out the R&D (customer) would be the entity eligible to claim R&D relief, not the subcontractor. The reasoning behind this principle is that it allows the company making the decision to do the R&D and bearing the financial risk to claim R&D relief.
