Through the SME scheme, you can claim tax relief on your R&D projects. This R&D tax relief allows your company to deduct an additional 86% of qualifying expenditure from your trading profit for tax purposes, on top of the standard 100% deduction, resulting in a total deduction of 186%. Additionally, if your company has claimed this relief and incurred a loss, you can claim a payable tax credit.

Before April 2023 expenditure
For expenditure before April 2023, the R&D SME Scheme allows companies to claim up to 33% of research and development costs. This is because if your SME is profitable, you can deduct an extra 130% of qualifying R&D costs from yearly profits. This is on top of the normal 100%, making a total 230% deduction. If you’re not profitable, that’s also okay! If you are loss making, you can claim up to 14.5% of the surrenderable loss.
April 2023 changes
For expenditure on or after April 1 2023, the additional deduction for SMEs will decrease from 130% to 86%, and the SME R&D Tax Credit rates will reduce from 14.5% to 10%. If, however, your company is loss making but classed as R&D intensive (where qualifying R&D spend adds up to at least 40% of total spend) you’ll still be able to claim using the 14.5% credit rate.
For accounting periods beginning on or after April 2024
The SME scheme is being replaced by Enhanced R&D Intensive Support (ERIS). This is only available for loss-making R&D intensive SMEs (whose qualifying R&D expenditure covers at least 30% of their total expenditure). SMEs who do not meet this criteria may still be eligible for R&D relief through the new Merged R&D Expenditure Credit scheme.
If you’re a small/medium enterprise carrying out R&D and looking for tax relief, HMRC needs to see that you meet these key thresholds:
· Staff headcount is less than 500
· Turnover is less than €100m, or your balance sheets total less than €86m (regardless of your headcount).*
*You will need to convert turnover from sterling to euros.
If you pass these criteria, and you’re a UK limited company that’s subject to UK corporation tax, then it’s likely that you’ll qualify. If you don’t meet these criteria, but you’re still conducting R&D, you can still look to claim under the Research and Development Expenditure Credit (RDEC).
To qualify for the R&D SME scheme, your project must:
· Look for an advance in science and technology
· Face uncertainty with achieving this advance
· At least have tried to overcome the uncertainty
· Not be easily worked out by a professional in the field
You cannot claim the tax relief for a project if the R&D work has been subcontracted to you, or if you’ve received State aid. You also can’t claim for any subsidised work (e.g., work paid for by a grant) however, you may be able to claim for a portion of your work if not all of your expenditure was subsidised.

There are a variety of different costs that qualify for R&D relief. These include:
· Consumables
· Salary
· Externally provided workers (EPW)
· Software licences
· Sub-contractors
From April 2023, it is also be possible to claim for pure mathematics, cloud computing, licence payments for datasets and data analytics.
Some costs can’t be claimed. These include:
· Production and distribution costs
· Capital expenditure on buildings and equipment
· The cost of land
· The creation of patents and trademarks.
