Finance Bill

My hon. Friend brings me to the point that I wanted to move on to: the report that the Chancellor of the Exchequer commissioned in Budget 2011 to evaluate the Exchequer impact of the additional rate of income tax. The report was published alongside Budget 2012. It concluded that the underlying yield from the increase from 40% to 50% was much lower than originally forecast, owing to large behavioural effects—it was possibly only £1 billion and could in fact be negative. The 50% rate also risked damaging growth and the UK economy if it had remained permanent.
