CIRD80200 - R&D tax relief: background

Historically, UK spending on R&D, as a proportion of Gross Domestic Product, has lagged behind that of many other countries. R&D suffers from a market failure 鈥� a positive externailty, whereby a company doing R&D does not receive the full benefit of that expenditure, because other persons also benefit. The amount of R&D done overall is therefore less than is optimal. The Government, as part of its agenda to build a modern knowledge based economy, and improve productivity, therefore supports 搁&补尘辫;顿听by providing additional tax relief.听听听

There are two R&D tax reliefs:听

  • Small or Medium Enterprise (SME) Tax relief听

  • Research and Development Tax Credit (RDEC).听听

A general overview of R&D tax relief and a comparison of the reliefs is at听CIRD80250.

Because the SME relief is targeted at a particular class of companies, it still has to come within the EU rules on State aid (CIRD81670)听.听

There is more detailed guidance on what is meant by an SME at听CIRD91000听onwards.听
