How to calculate R&D tax credits for SMEs

Regardless if your company is profit- or loss-making, you can still benefit from R&D tax-credits.

For profit-making businesses:

You’ll receive a reduction in your Corporation Tax bill. The rate of relief is calculated at 25% of qualifying R&D spend. If you spent £50,000, you could get a £12,500 reduction on your tax bill.

For loss-making businesses:

As there are no tax liabilities as of yet, you’ll receive your benefit as a cash payment. The rate of relief is up to 33%, meaning for a £50,000 R&D spend, you could get a cash injection of £16,500.

How to calculate RDEC benefit

Research and Development Expenditure Credit (RDEC) is targeted towards large companies. SMEs who are unable to claim under the scheme can also apply for RDEC.

RDEC is received as a taxable benefit, calculated from 13% of your associated R&D costs, you’ll receive a cash benefit of 11% (after tax). This amount can be offset against your tax bill, or if no tax is owed, you’ll receive the amount as a cash payment.

For example, if you spend £100,000 on R&D, you can get an £11,000 benefit as a corporate tax reduction or as a cash injection.

How accurate is our R&D tax credit calculator?

Whilst the calculator is helpful to understand the potential for R&D tax credits to benefit your business, the tool is indicative and no substitute for professional advice. Identifying eligible projects and their boundaries and costs requires a detailed knowledge of the legislation and the application of suitable financial methodology based on the nature of your business and your records for R&D.

R&D tax credit calculations – FAQs

We know that the R&D legislation can be dense and daunting, so we answered some of the most frequently asked questions in a clear and simple way below. If you still have a question or want to know more, please contact us, we’d love to hear from you.

An R&D expense is any expenditure which the R&D legislation associated with your investment in R&D. Companies who are spending money in their risk-taking projects with science and technology may be investing in R&D for tax purposes. And, if eligible, you can claim back tax on some of these costs in the form of R&D tax credits. For the purpose of R&D tax credits, qualifying costs include staff costs (including subcontractors), consumables (including light, heat and water), and software.

You can read more about how costs are calculated for each category.

For loss-making companies, you have two options. Carry the additional loss forward where it will be offset against future taxable profits, or choose for 230% of qualifying expenditure – or revised loss – for the period (whichever is lower) to be surrendered to HMRC in exchange for a cash tax credit worth 14.5%.

For an example of calculating R&D tax credits for a loss-making company, you can read our piece on calculating R&D tax credits.

The SME incentive is for businesses with fewer than 500 staff, a turnover of less than €100m, and less than €86m of gross assets. RDEC is typically for larger business with more than 500 employees and a turnover of more than €100m. SMEs who have been subcontracted to do R&D work can also claim under RDEC. The maximum rate of benefit available is different for each scheme.
