Financial Reliefs or Incentives
HMRC provide a number of financial reliefs or incentives to encourage businesses to invest in innovation. These include:
- Research & Development (R&D) Tax Reliefs or credits and R&D allowances (RDA)
- Patent Box
- Innovation and growth grants
- Intellectual property and creative sector
From 1 April 2024, HMRC has merged the existing SME and RDEC schemes into a single, streamlined R&D Expenditure Credit (RDEC) system, with enhanced support for R&D-intensive SMEs (ERIS). While the qualifying expenditure rules remain the same, the calculation and tax treatment differ.
Under the new scheme:
- A lower notional tax restriction is applied at step 2 of the payment process for small profit-making and loss-making businesses.
-
A more generous PAYE cap is available, making the relief more accessible.
👉 Use our R&D Tax Relief Calculator to estimate your potential claim.
The table below outlines the potential tax savings available under each scheme.
