The net benefit after
tax of the relief ranges from 7.7 per cent to 32.63 per cent of eligible expenditure depending on whether the claimant is a large or small profitable or loss making company. The definitions of large and small company size are driven by the
EU classifications (and adjusted for UK R&D Tax Credit purposes) including revenues, number of
employees and
balance sheet assets. The SME scheme works by allowing the SME to deduct an additional 130 per cent of its eligible R&D costs from its
taxable income (a superdeduction). If the company has made a loss, then the scheme goes even further and allows the alternative of a cash payment of up to 32.63 per cent of the eligible R&D investment. The rate of the SME R&D tax
credit enhancement has increased from 150 per cent when it was first introduced in 2000 to the rate of 225 per cent as at 2013. The
Chancellor of the Exchequer announced in his 2014 Autumn Statement that the super deduction rate for the SME relief regime has been increased from 225% to 230%, on expenditure incurred from 1 April 2015, providing a benefit of 26% of the qualifying expenditure. The rate at which losses can be surrendered for a payable tax credit under the SME scheme remains at 14.5%, meaning loss making SME’s can receive a cash credit of 33.35 pence (previously 32.63 pence) for every pound spent on qualifying R&D. A large company is able to claim an additional 30 per cent of its eligible R&D costs from its taxable income as a superdeduction. And with effect for qualifying expenditure incurred after 1 April 2013, the government introduced a new
Research and Development Expenditure Credit (RDEC) which operates above the tax line, and until 2016, alongside the existing superdeduction scheme. The RDEC scheme makes it possible for large companies to claim a payable tax credit at a rate of 10 per cent of qualifying expenditure (rising to 11 per cent of qualifying expenditure incurred from 1 April 2015). This was further increased to 12% from 1 January 2018.
HMRC publish full details of the progression of the
tax deduction and payable credit rates on their website . The steady state cost of the whole scheme is approximately £1.3 billion per annum in terms of corporation tax revenues foregone by HM Treasury. As at 2013, nearly 100,000 claims have been made and over £9.5 billion of relief has been claimed since the R&D tax credit scheme was launched. More than 28,000 different companies have made claims under the SME scheme, and 7,500 under the large company scheme HMRC has also published an evaluation study of the uptake and impact of the scheme as at 2010 . ==SME and Large Company status for R&D tax relief purposes==
