Finance (No.2) Bill

Amendment 4 and new clause 4, tabled by Opposition parties, deal with familiar matters that we debate every year. They propose, once again, that within three months of passing the Finance Act, the Chancellor should publish a report reviewing the impact of setting the additional rate at 50%. In addition, amendment 4 asks for an assessment of the impact of setting the additional rate for 2014-15 at 45% and at 50% on the amount of income tax currently paid by those with taxable incomes of over £150,000 and over £1 million per year. Needless to say, such an analysis, in order to be credible, would need to take behavioural impacts into account, as did the HMRC report on the additional rate published at Budget 2012. When increasing taxes, it is not enough merely to look at theoretical income tax liabilities. Let me assure hon. Members, once more, that this Government already consider the impact of any policy decisions taken. The HMRC report on the additional rate concluded that the underlying yield from the introduction of the 50p rate was much lower than originally forecast due to large behavioural effects. It even said that it is possible that the 50p rate could have reduced income tax revenue instead of increasing it. It would be illogical and unfair to reintroduce a tax rate that is ineffective at raising revenue from high earners and that would end up making ordinary taxpayers pay more and risk damaging growth.
