R&D-intensive companies are those that have R&D expenditure constituting at least 30% of total tax-deductible P&L expenses plus capitalised R&D costs. Loss-making R&D intensive companies can claim a payable credit rate of 14.5% from HMRC in exchange for their losses (capped at £20,000 plus 3 x [PAYE & NIC]).
Previously, most SMEs used the enhanced expenditure scheme, but with a payable tax credit rate for losses of 10% (or 14.5%, from 1 April 2023, for those with R&D expenditure constituting at least 40% of total expenditure).
