Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment has been made of the implications of the Laffer Curve on net tax income receipts due to the 60% marginal rate of income tax on incomes between £100,000 and £125,140.

The Government recognises that taxpayers earning between £100,000 and £125,140 face a higher marginal tax rate due to the tapering of the tax-free Personal Allowance, introduced in 2010-11.
