Eligible loss-making R&D-intensive SMEs may qualify for enhanced relief instead.

How this estimate works
  • The merged scheme starts with a taxable credit of 20% of qualifying costs for accounting periods beginning on or after 1 April 2024. This tool excludes ring-fenced oil and gas trades.
  • The tax examples use 25% and 19%. The actual tax effect and payment depend on your company’s position, including marginal relief, liabilities and the PAYE cap. This is not a claim or refund calculation.
  • Eligibility, qualifying costs, overseas work and contracting arrangements need checking. Enhanced R&D-intensive support (ERIS) has separate eligibility and loss calculations.
