How to calculate R&D tax credits for SMEs?

The financial status of your SME will determine the rates of R&D tax credits, whether it's making a profit or facing a loss. Generally, an SME can get up to 27% benefit from this relief. SMEs trading at a profit or loss can calculate their entitlement based on the calculation of R&D tax credit using the R&D enhancement. The R&D enhancement is calculated at 86% of the qualifying expenditures which is then added back onto the qualifying expenditures to give you the enhanced expenditure (186%).

Loss-making SMEs

For companies trading at a loss and claiming before April 2023, we are able to retrieve your R&D entitlement up to 33.35% in the form of a cash benefit. So for every £100 spent on qualifying R&D expenditure, we can claim back up to £33.35. This is done by applying the enhancement rate of 130% to all qualifying expenditure. We can then surrender the revised loss figure at the surrender rate of 14.5% to give us your payable tax credits.
For example: If your company has spent £500,000 on qualifying R&D expenses, we can look to claim back up to £108,750.
Note: Any claims made after April 2023, the respective rates will decrease from 33.4% to 18.6%.

Example of a loss-making SME

Description Amount
Qualifying R&D expenditure £500,000
R&D enhancement at 130% £650,000
R&D enhanced expenditure totalling 230% £1,150,000
Loss for the financial year -£100,000
Loss after R&D relief -£750,000
Surrenderable loss £750,000
Entitlement Payable at 14.5% £108,750

Profit-making SMEs

For companies trading at a profit and claiming before April 2023, the entitlement received received will be up to 24.7% in the form of a corporation tax reduction or refund for tax already paid to HMRC. This is calculated in a similar way to loss-making SMEs apart from the entitlement will be calculated on the revised profit figure for the year at the current corporation tax rate of 19%.
For example: If the company has a total qualifying R&D expenditure of £500,000, depending on the company's tax position, we are able to retrieve the entitlement of up to £123,500 in the form of a corporation tax reduction/rebate.
Note: Any claims made after April 2023, the respective rates will decrease from 24.7% to 21.5%.

Example of a profit-making SME

Description Amount
Qualifying R&D expenditure £500,000
R&D enhancement at 130% £650,000
R&D enhanced expenditure totalling 230% £1,150,000
Profit for the financial year £750,000
Profit after R&D relief £100,000
Corporation Tax reduction £123,500

For companies claiming for periods starting before April 1st, 2023, the current rate of 130% of qualifying expenses will apply. For companies claiming R&D relief for periods starting on or after April 1st, 2023, their entitlement will be calculated at 86% of the qualifying expenses.

How to calculate RDEC?

The RDEC rate has been established at 20% amid the recent changes to R&D tax relief. Businesses are now able to recover up to 20p for every £1 invested in eligible R&D activities. This rate remains consistent irrespective of the financial circumstances, as opposed to the SME scheme.
Estimated R&D expenditure: £500,000 at the RDEC enhancement rate of 13% = £65,000
= £565,000 as above-the-line credit
Calculate the benefit at a corporation tax rate of 19% = £107,350

What are R&D qualifying costs?

Staff PAYE costs/Pension contributions

Your company is eligible to request reimbursement for salaries, wages, class 1 NIC (National Insurance Contributions), and pension fund contributions paid to employees who are directly and actively involved in the R&D projects.

Subcontracted costs

These costs pertain to payments made to an external agency for individuals directly and actively involved in the R&D project. These individuals are not employees or subcontractors but are engaged through the agency. Typically, relief is provided for 65% of the payments to the staff provider.

Materials and consumables

Your company is eligible to seek reimbursement for the expenses incurred on items that are directly used and consumed in qualifying R&D projects. These expenses cover materials, water, fuel, and power utilised in the R&D process.

Software purchases

The expenses related to operating systems, software platforms, and permissions granted for accessing and utilising digital data that is directly used in your R&D activities can be reimbursed. You may need to allocate the costs of partially used software appropriately to determine the eligible amount for the claim.

Travel costs

Certain travel expenses associated with your research and development may also be eligible for your claim. These costs include collaboration, attending relevant events, visiting research sites, or conducting fieldwork directly tied to your R&D projects.


Utilities such as water, gas, and oil can also be claimed as part of eligible costs. However, it is important to note that only the portion of utilities used exclusively for R&D purposes will be eligible, not the entire utility bills.
