R&D tax credits in 2026: who qualifies and how much you can claim

If your company is resolving 'scientific or technological uncertainty' that a competent professional in the field couldn't easily solve, you may qualify. Software development, engineering, biotech and product design are the most common sectors.

For accounting periods beginning on or after 1 April 2024, the merged expenditure credit rate is 20%. Enhanced support for eligible loss-making R&D-intensive SMEs has separate conditions, including the current intensity threshold. The cash effect depends on the company's tax and loss position, so do not treat the headline rate as the amount received.

Use a specialist who tests eligibility, documents the scientific or technological uncertainty, links costs to specific projects and explains the claim methodology. The company remains responsible for the accuracy of its return even when an adviser prepares the claim.
