Scotland Bill

No, it is not, and if the hon. Lady looks at later amendments she will find that an entire series of them is related to the commencement powers, precisely to ensure that the right things are done at the right time, with the agreement of everybody involved. We will consider that, and I hope the hon. Lady is still present in the Chamber when we do so. Two specific corporation tax issues relate directly to the Bill's provisions. Existing provisions allow assigned revenue from a share of income tax—one large tax and a chunk from that, and lots of small measures. It would be much better if there was a balanced basket of taxes, so there was not an over-dependence on, and therefore a potential volatility from, having such a large amount of assigned revenue from a single tax. It would also be preferable if there was a personal tax and business taxes, so that they could be offset. It would also, of course, be preferable to remove the perverse disincentive under the Bill in respect of any future Scottish Government reducing income tax. Let us imagine that a Government decided that, for whatever reason, that such a measure might be sensible to stimulate growth, but the Scottish Government took the hit in reduced revenue yield from income tax while the UK Government took the benefit of increased corporation tax. The effect of having only a large personal tax, and not a significant business tax, is that it unfairly and unnecessarily removes the number of economic or fiscal levers open to the Scottish Government. That is an important point.
