Scotland Bill

My Lords, the amendment seeks to outlaw the practice, which my noble friend laid bare before us at an earlier stage of the Bill, whereby the Scottish Parliament is able to raise 10p in income tax but, if the tax base is narrowed, the Treasury sends it a cheque. The current Budget, quite rightly, raised the threshold at which people pay income tax, which will be very beneficial to people in Scotland. If this system were in operation today, not only would everyone enjoy a lower tax on their income in Scotland but the Treasury would send a cheque for the equivalent amount in the reduction in the tax base to add to the block grant—which drives a coach and horses through the whole idea behind this Bill, of bringing accountability to the spending practices of the Scottish Parliament. It should not be compensated for a reduction in the tax base that arises from a reduction in income tax in the rest of the United Kingdom. It is an absurd proposal. I am very nervous that my noble friend may accept this amendment, because it extends the powers of the Scottish Parliament very considerably, in a constructive way. I know my noble friend, at an earlier stage in the Bill, said that the Scottish Parliament cannot change the allowances, and therefore the reduction in revenue would be as a result of something that was done in the United Kingdom. The amendment provides for the Scottish Parliament to be able to change the allowances and gives it more power. I listened to the noble Lord, Lord Kerr, and can see the logic of that. My noble friend may not like that at all, because it adds to the complexity of the devolution of income tax. I noticed he said earlier that the block grant would be about 60 per cent of the expenditure. We keep hearing that the Parliament will be raising 35 per cent of its own expenditure through tax—but that is a dishonest figure. The amount that will be raised by the 10p on income tax is about £4.5 billion. We are looking forward to discussing this later today, but it just so happens that when the Barnett committee, which was established as a result of the efforts of the noble Lord, Lord Barnett, looked at this, the estimates of the additional grant that Scotland had over and above what would be based on needs was about £4.5 billion. That is what 10p on income tax, broadly speaking, will raise. It is about 15 per cent of the block grant and it has all the problems that we have with local government finance, where a small increase in expenditure needs a large increase in income, because of the gearing effect. Therefore, it may be sensible to broaden the tax base, which is another reason for having additional sources of revenue other than income tax, such as the aggregates tax and so on and so forth. I can see myself being sucked into this process of additional tax-raising powers. It is the slippery slope that my noble friend Lord Lang referred to. The purpose of this amendment is to deliver what all those advocates of this Bill, whom I have spent most of my life opposing, say that the Bill is about and to remove this extraordinary idea that Scotland should benefit both ways—and no self-respecting Scot would want this—by getting both the reduction in the tax and the additional grant. It is very straightforward and because the hour is late, I will not elaborate on it any further. I beg to move.
