Merged R&D scheme- what you need to know

The merged R&D tax relief scheme was confirmed in the Autumn Statement in 2023 and has been introduced for accounting periods beginning on or after April 1 2024. The new scheme represents a significant change to R&D tax incentives in a very short timeframe, so it’s imperative that your business understands how the merged scheme will affect your R&D tax claims going forward.

What is the merged R&D scheme?

The merged R&D scheme sees two of the UK’s current R&D tax relief incentives brought together into a single scheme:

  • Enhanced tax relief and payable credits for qualifying SME expenditure.
  • R&D expenditure credit (RDEC) for large businesses, SME subcontractors and subsidised R&D expenditure.

The merged scheme is sometimes referred to as the R&D single scheme, simplified scheme or new RDEC. The merged scheme has been implemented in a similar way to the existing RDEC scheme with a few notable distinctions.

 

 

Who is impacted by the merged R&D scheme?

If you’re claiming R&D tax relief, it is likely that you will be impacted by the introduction of the merged scheme.

Despite the intention to simplify R&D tax relief by merging the previous SME and RDEC schemes, there are still differences you need to be aware of depending on the type of business you are and the contractual arrangements under which you are carrying out R&D.

If you’re an SME, you need to identify whether you fall under the R&D intensive incentive or the merged scheme. Remember, to be classed as an SME for R&D tax purposes you must have fewer than 500 staff, and either a turnover of no more than €100 million or gross assets of no more than €86 million.

You will also need to consider whether the decision to carry out R&D sits within your business or elsewhere in the supply chain. Generally, companies will not be able to make a claim if R&D has been contracted to them.

To find out more about the changes specific to you, follow the links below.

Are you: 

  • An SME with less than 30% of total expenditure on qualifying R&D (the threshold to qualify for an enhanced rate for R&D intensive SMEs).
  • An SME SUBCONTRACTOR OR SME WITH SUBSIDISED R&D currently claiming under RDEC. Remember, the treatment has changed under the merged scheme.
  • A loss-making R&D INTENSIVE SME with more than 30% of total expenditure on qualifying R&D.
  • A LARGE COMPANY with 500 or more staff and either more than €100 million turnover or €86 million gross assets.

Why was the merged R&D scheme introduced?

The government’s intention with R&D tax incentives is to support private sector investment in innovation, benefitting the UK economy by boosting productivity and growth. A number of changes to R&D tax reliefs have been made since 2021, with the aim of simplifying the incentive and protecting it from abuse. The merged scheme represents both the latest change and the conclusion of this period of consultation.

What are the merged R&D scheme rates?

The table below shows how R&D tax relief rates have changed in recent years. The merged scheme applies for accounting periods beginning on or after 1 April 2024.

Current incentives Current incentives Merged scheme
Your business SME R&D tax incentive RDEC Merged scheme SME intensive scheme
Company type Before 1 April 2023 After 1 April 2023 Before 1 April 2023 From 1 April 2023 From 1 April 2024 From 1 April 2024
Loss-making SME Up to 33.35% Up to 18.6% 10.5% 15% 16.2%
Profit-making SME Up to 24.7% Up to 21.5% 10.5% Up to 16.2% Up to 16.2%
R&D intensive SME Up to 27% Up to 27%
Large company 10.5% Up to 16.2% Up to 16.2%

When did the the merged R&D scheme come into force?

The merged scheme for R&D tax relief applies for accounting periods beginning on or after 1 April 2024. It’s important to note that this is not for expenditure incurred from the start of April as previously proposed.

So a business that prepares accounts to 31 December each year will enter the merged scheme for the first time when considering an R&D claim for its accounting period ending 31 December 2025, whereas one which makes up accounts to March will enter for its 31 March 2025 period. 

The changeover for businesses is simplified, with no need to claim under different regimes for an accounting period that straddles 1 April 2024. The commencement date means that implementation of the merged scheme for some businesses will be later than previously planned.

How does the merged scheme work?

The merged R&D scheme has been  implemented in a way that resembles the research and development expenditure credit (RDEC). However, key points to note include:

An above the line expenditure credit

All companies, regardless of size (with the exception of R&D intensive SMEs) will receive an above the line credit under the merged scheme. This means a credit that can be offset against your tax liability, or subject to some adjustment, paid in cash to your business.

How it differs from RDEC

There are some notable distinctions from the current RDEC scheme, usually where aspects of the current SME scheme have been incorporated into the merged scheme. The most significant difference is the rules for contracted out R&D. As well as this, businesses that currently claim RDEC should be aware of the following:

  • PAYE/NICs – the merged scheme legislation incorporates the more generous version of the payable credit cap found in the current SME scheme. Read more background on this in our blog on the SME cap.
  • Overseas R&D – previously delayed limitations on relief for overseas expenditures on EPWs and subcontracted R&D are included.

The treatment of contracted out R&D

Subcontracted R&D is a particularly complex area and was a central consideration when it came to the merging of the SME and RDEC schemes. ForrestBrown was actively involved in policy discussions on this issue.

The merged scheme aims to target R&D tax relief to the company making the decision to carry out R&D and in turn bearing the risk. This was reflected in the draft Finance Bill and detailed in a technical note published alongside the Autumn Statement 2023. This later became the Finance Act in 2024, including a more detailed legislative definition of contracted out R&D.

The subcontracted R&D rules incorporated into the merged scheme are modelled on the existing SME scheme rules. As such, generally companies will not be able to make a claim for RDEC if R&D has been contracted to them. However, where a company with a valid R&D project contracts a third party to undertake R&D activities on its behalf, the company may claim the qualifying costs of that work.

Despite being modelled on the existing SME scheme, the legislative definition of contracted out R&D is new and therefore as a business you need to carefully consider your position in any supply chain to determine the correct position under the merged scheme.

The subcontracted R&D rules represent a significant change that affects many businesses, both large and small. Large companies need to evaluate how the new rules apply to commercial structures and contracts, potentially for the first time. 

For SMEs, there has been some uncertainty in recent years regarding the implementation of current rules restricting SME R&D tax relief for R&D contracted to a company. This change therefore risks adding further uncertainty to an already contentious area. Finally, any businesses currently claiming under RDEC for R&D contracted to them are unlikely to be able to claim under the merged scheme because the cost of that R&D will form part of the R&D claim for the contracting company.

The impact of this move on complex R&D supply chains is an area of some concern. There was insufficient time to properly understand the full ramifications of these changes before they were implemented.

There are some scenarios where a subcontractor can claim R&D tax relief. These include when a company carries out R&D for a contractor which is not a tax-paying entity, such as charities, universities, scientific research organisations, as well as overseas entities.

Subsidised expenditure

Existing rules on subsidised expenditure which apply to the SME incentive are not part of the new merged R&D scheme. While restrictions were included in earlier drafts of the legislation, the removal of these provisions avoids a potential area of major disruption for larger businesses.

If you are in receipt of a subsidy or grant funding for your R&D activity, you will no longer see the amount of available R&D relief reduced (as currently happens under the SME scheme).

This is a welcome simplification, particularly given recent controversy regarding HMRC’s application of the legislative provisions restricting relief for subsidised R&D expenditure. ForrestBrown secured a landmark victory against HMRC in a tribunal case dealing with subsidised expenditure, after our client, Quinn (London) Limited, was wrongly denied SME R&D tax relief funding totalling over £1 million.

Key points for profit-making and non-R&D intensive loss-making SMEs

If your business spends less than 30% of your total expenditure on qualifying R&D then, for your first accounting period beginning on or after 1 April 2024, you will need to claim R&D via the merged scheme. You should be aware of the following important changes:

 

Key points for large companies, SME subcontractors and SMEs with subsidised R&D

Although the merged scheme is based on the RDEC relief scheme, there are some key areas of impact for large companies:

  • New restrictions on claiming for R&D contracted out to the company.
  • Changes to the PAYE/NIC cap on any payable RDEC.
  • Eligibility of payments to R&D subcontractors.
  • Restrictions on eligible expenditure for overseas EPWs.

Key points for loss-making R&D intensive SMEs

Alongside the newly merged R&D scheme, the enhanced rate for R&D intensive loss-making SMEs (introduced in April 2023) continues to operate under the current SME model. For expenditure incurred on or after 1 April 2023, loss-making R&D intensive SMEs have been eligible for an expenditure enhancement of 86% and a payable credit of 14.5% (although this provision was retrospectively implemented as part of the Finance Act 2024).

For accounting periods beginning on or after 1 April 2024, if you’re a business spending 30% or more of your overall business expenditure on R&D, and you’re loss-making for tax purposes, then you will qualify for the enhanced rate. This intensity threshold is a reduction of 10% from the threshold introduced on 1 April 2023. 

Find out more about Enhanced R&D intensive support (ERIS).

 

A one-year grace period  applies for companies who dip under the 30% threshold for R&D intensive SMEs. This should protect businesses from moving in and out of the R&D intensive scheme retrospectively, avoiding uncertainty around financial planning and investment decisions.

Restrictions around subsidised R&D have been removed for R&D intensive SMEs for accounting periods beginning on or after 1 April 2024.

Key points for R&D intensive SMEs

Loss-making R&D intensive SMEs who meet the 40% threshold have remained within the SME scheme post 1 April 2024. It’s still worth considering how the changes affect them.

Loss-making SMEs whose R&D expenditure is greater than 30% of total spend, but less than 40%, are eligible for the enhanced SME rate for their first accounting period beginning on or after 1 April 2024.

Key considerations for these companies include:

  • The new definition of contracted out R&D.
  • Restrictions on eligible expenditure for overseas EPWs and subcontractors.
  • The removal of restrictions for subsidised R&D expenditure.
