Small and medium-sized companies
For R&D tax purposes, an SME is defined as having fewer than 500 employees and either turnover not exceeding £100 million or gross assets not exceeding £86 million.
SMEs with less than 30% qualifying R&D spend claim under the merged scheme. A qualifying loss-making SME with R&D intensity of at least 30% may instead qualify for Enhanced R&D Intensive Support.
