Under the SME scheme from 1 April 2023 (up to the introduction of the Merged Scheme), for example, if all the costs (salary, materials, ancillary) total £200,000 per account. The enhanced additional tax deduction is 86%.
Therefore another £172,000 (86% of £200,000) is deducted from the taxable profit in the tax computations submitted to HM Revenue & Customs.
This results in a tax saving of £43,000 (25% company tax on £172,000).
Additional tax deduction results in a repayment of overpaid company tax or a cash cheque from HMRC of 10% of the additional deduction. In this case £17,200 (10% of £172,000).
This deduction does not affect the accounting profit so has no impact on profit reporting to third parties such as customers, suppliers and lenders.
Under the Merged Scheme, for qualifying R&D expenditure of £200,000, a taxable expenditure credit of £40,000 may arise. After taking account of corporation tax and the company’s circumstances, the net benefit is typically around £30,000.
