Scotland Bill — House of Commons, 2015-06-29
Topic: Macroeconomics
Nigel John Mills (Conservative, Centre-right): I rise as a reluctant supporter of the devolution of income tax to the different countries of the Union. I agree with the hon. Member for Edinburgh South (Ian Murray) that people throughout the United Kingdom should feel that they are paying the most important tax—the tax that puts the largest amount of money into the UK pot—and seeing it redistributed. We are where we are, however, and we are talking about devolving income tax to Scotland I fear that we have one foot in each camp, with part of the tax in this Parliament and part of it in the Scottish Parliament, and that we will end up in a real mess. I am not sure how it is possible to make a tax work when a Parliament can set the rate, the bands and the starting point, but not the actual rules. A particular policy issue in Scotland may mean that the Scottish Parliament rightly wants to incentivise certain employment and income activities. That may not be not a priority for the United Kingdom as a whole, perhaps for reasons of scale or owing to a different approach, but there will be no mechanism enabling income tax in Scotland to promote that certain activity. A new tax relief for people working in the offshore oil and gas industry, for instance, might not be a priority for the UK as a whole, but it might be a priority in Scotland. The record of our income tax code is cluttered with examples of the use of the tax code to promote certain types of behaviour. I am not sure that we can secure the full and effective use of a tax code if our Parliament is not setting the rate and looking after local activities The flipside will be that tax avoidance as a result of a loophole may become material for the Scottish Parliament in the case of a certain piece of exploitation, but will not become material to the budget of the whole UK. It may be extremely important in Scotland to get that loophole closed, but in the UK there may be several others that are ahead of it in the queue, because it does not represent a large loss to the Westminster Parliament. An action that ought to be taken on something that has a material impact in one part of the UK will not be taken because of the strange disparity that exists If we are going to start devolving taxes, we should step back and have a look at what a federal UK tax system would be like. We should work out which taxes are federal and which are devolved, and then try to bring about some consistency in Wales, Scotland and Northern Ireland so that similar taxes can be devolved in the same way, rather than adopting a piecemeal approach in regard to corporation tax in Northern Ireland, income tax in Scotland, and so forth. I do not think that anyone in the country will know to which Parliament they are paying what tax, and who has complete control of it. That means that we will not get all the advantages that we expect, such as the ownership and the accountability that my hon. Friend the Member for Gainsborough (Sir Edward Leigh) mentioned I do not think that we are achieving the sharing and the pooling that the hon. Member for Edinburgh South wanted, the coherent use of income tax that the SNP wants, or the full devolution that would make sense. We appear to have become involved in a strange halfway fudge which we may regret in a few years’ time. I think it would be better to step back and try to get this right from the start, rather than trying to find a way of clearing up the mess I accept that there are always good reasons why the line is drawn where it is. We must be very careful about tax avoidance through the use of residency, or pretend residency. If I am working full-time in Scotland, to get the Scottish rate—which may be higher or lower than the rate in the rest of the UK—I shall probably have to go and live in Scotland. I suspect that I cannot achieve that artificially. If I have large dividend flows, I can probably pretend that I am in Edinburgh when I am in London and vice versa in order to obtain the tax advantage. I can see why there is an attraction in having one UK-wide passive income tax, rather than an active tax.
