I am grateful to my hon. Friend. Of course, he was in the Department and has a business background, so he knows the detail and the importance of R&D tax reliefs. I am sure that my hon. Friend the Financial Secretary to the Treasury will have a chance to look at that later. I believe that we will be having a meeting about a separate issue of concern—a certain railway project that matters to him—when we can also discuss these points.
I turn to the specific detail. For expenditure on or after 1 April 2023, the research and development expenditure credit rate will increase from 13% to 20%. The small and medium-sized enterprise additional deduction will decrease from 130% to 86%, and the SME scheme credit rate will decrease from 14.5% to 10%. That reform will ensure that the taxpayer support is as effective as possible. It improves the competitiveness of the RDEC scheme and is a step towards a simplified RDEC-like scheme for all.
That means that Government support for the reliefs will continue to rise in cost to the Exchequer—from £6.6 billion in 2021 to more than £9 billion in 2027-28—but in a way that ensures value for money. To be clear, the R&D reliefs will support £60 billion of business R&D in 2027-28, which is a 60% increase from £40 billion in 2020-21. The Government will consult on the design of a single scheme and, ahead of the spring Budget, work with industry to understand whether further support is necessary for R&D-intensive SMEs without significant change to the overall cost.
