I will be brief.
Mike Kane said that paying corporation tax was an optional extra. If he is right—and there are some good arguments for why he might be right—it is because of the unbridled complexity of the system. I used to carry a number in my head: I thought that the tax code was 11,000 pages long. However, when I went to a Public Accounts Committee tax conference organised by Dame Margaret Hodge—the Dame Professor Lady right hon. Member for Barking—I discovered that it was 17,000 pages long, and I was told on the radio yesterday that the figure might now be nearer 20,000.
If we made the Bible 10 times longer, we would not expect there to be less work for theologians. We need to sort this out. Complexity is not always avoidable in a mature economy, but there are steps that can be taken to make the code simpler. The Office of Tax Simplification examined 155 different tax reliefs and recommended that 47 should be abolished—43 actually were abolished—but over the same period, the Government of the day introduced 134 new reliefs. According to the Office of Tax Simplification, that produced a total of 1,140. Incidentally, HMRC had thought that there were only 398, which shows how extraordinarily complex the system has become.
That is the central problem, and it needs to be tackled. If a system that can only be dealt with by a high priestly caste is combined with a global economy, a country will get what we have got. It was this Government who introduced the idea of an Office of Tax Simplification, and it is this Government who are starting to do something about flattening and simplifying the tax system.
There is also the question of the cost of tax reliefs, which is sometimes much higher than HMRC expects. When the right hon. Member for Barking was the films Minister, for very good reasons she introduced a film tax credit. She was then horrified to discover that, using the law of the land, some very clever entrepreneurs and accountants were going around doing things which bore some relation to UK film activity, but perhaps too tangentially for the right hon. Lady’s taste. Much of what had been done was found by the courts to be within the law, and ended up costing HMRC, and taxpayers, hundreds of millions of pounds more than had been expected.
This Government are starting to tackle the problem. They have not made all the progress that they need to make, because this is a very big problem indeed, but at least they are starting to tackle it. The last Government did not collect the tax, but this Government are moving in the right direction, and I commend them for what they are doing.
