My hon. Friend is right. This comes back to the impact of the choices being made—who is being prioritised and who is not, who is bearing the greater share of the burden and who is not. That is the material point.
We know that the Government’s impact assessment prepared for the 2014 Budget estimates that the cost to the Exchequer of the corporation tax cut would be some £400 million in 2015-16, £785 million in 2016-17 and £865 million the following year. In the 2015 Budget Red Book the estimates are revised upwards: for 2015-16 £550 million, for 2016-17 £1.045 billion, and for 2017-18 £1.1 billion. Those are not insignificant sums for a policy that affects a relatively small number of businesses. That is exactly my hon. Friend’s point.
The Government estimate that some 40,000 businesses pay the main rate of corporation tax and a further 41,000 businesses pay at the marginal relief rate. The Department for Business, Innovation and Skills estimates that the UK has some 5.2 million private sector businesses, the majority of which—3.9 million—are sole proprietorships, and 1 million have fewer than 10 employees. Clearly, if about 81,000 businesses benefit from the corporation tax cut, the opposite is also true—5.1 million businesses do not benefit in any way from that rate change.
The Government believe that a further cut in the corporation tax rate makes UK plc a more attractive place to invest and a more attractive destination for business to locate. The Minister and I have often debated the importance of the headline rate of corporation tax when that judgment call is made by businesses. It is important—a point that I have made on several occasions—but it is worth noting that on the former point it is far from clear that this is the case. We know that business investment fell from 8.2% of GDP in 2010 to 7.8% in 2013. That should not come as a big surprise.
Businesses tell us that they face a range of issues and that their decisions about where to locate and where to remain and invest are not based only on the headline rate of corporation tax. They take many other factors into account, such as infrastructure and the skills available in the labour market. Businesses often say that these factors are very important to their decision making, but they worry that under this Government those are areas of policy have not gone in the right direction.
