What is the UK Merged R&D Tax Relief Scheme?

The new UK Merged R&D Tax Relief Scheme (Merged RDEC) is a single, unified tax incentive operating for accounting periods. Replacing the legacy dual SME and RDEC regimes, it awards an ‘above-the-line’ 20% gross expenditure credit to qualifying UK companies investing in scientific or technological advancements. The scheme establishes standardized rules around software/cloud spend, overseas subcontractor restrictions, and mandatory advance notifications.

Merged R&D Tax Relief: Key Answers.

The merged UK R&D tax scheme replaces legacy RDEC and SME rules with a single 20% taxable credit. Find clear answers below on contractor claim rights, overseas spending limits, PAYE caps, and high-intensity ERIS eligibility.

The 20% gross credit is calculated on qualifying R&D expenditure and is treated as “above-the-line” taxable income. For profitable UK scaleups paying the 25% main rate of Corporation Tax, the credit yields a net tax offset of 15%. For loss-making companies, the credit is surrendered to HMRC for a direct tax refund paid at a net cash rate of approximately 15% to 16.2% after applicable notional tax deductions.

First-time claimants, or companies that have not submitted an R&D claim within the previous three years, must electronically submit a Claim Notification Form within 6 months following the end of the accounting period being claimed. Failure to file within this strict 6-month window results in the automatic disallowance of the entire claim.

Under current rules, expenditures on subcontractors and Externally Provided Workers (EPWs) qualify only if the R&D activities are physically performed within the UK or subject to UK PAYE/NICs. Overseas subcontracted spend is excluded unless strict exemption criteria are met—specifically where it is legally, geographically, or environmentally impossible to undertake the research within the UK.

Under the Merged Scheme, the right to claim generally sits with the company that initiates and subcontracts the R&D activity, provided it intended or contemplated that R&D would be required as part of the contract. Subcontractors performing the operational work cannot claim relief on those same expenditures unless the main contractor is an ineligible entity (e.g., an exempt body or overseas company.

To qualify for ERIS, a loss-making SME must dedicate at least 30% of its total operational expenditure (including connected company spend) to qualifying R&D activities. ERIS offers a higher financial yield, granting a 27% payable cash credit rate rather than the standard Merged Scheme rate.
