Generally, enhanced deductions on research and development (R&D) are available in respect of qualifying revenue R&D expenditure. Companies can claim an enhanced deduction at a rate that will depend on whether they are large or small and medium sized companies (SMEs). SMEs can claim a deduction from taxable profits of 225 percent of their qualifying R&D expenditure and. if loss making, will be able to claim a cash payment in return for forfeiting a proportion of their losses. Large companies may claim a deduction of 130 percent of their qualifying revenue R&D expenditure. Only certain expenses, e.g. a company’s own staff costs, are eligible.
R and D tax credits for large companies will continue as an alternative to the RDEC regime, until 31 March 2016, when the large company regime will end.
There is a separate regime for companies of all sizes where the R&D expenditure is capital in nature for tax purposes. This allows a 100 percent deduction as expenditure is incurred but does not provide any enhancement to amounts.
