JEAN-BAPTISTE COLBERT, Louis XIV’s finance minister, famously said that the art of taxation was like plucking a goose; the aim was to get the most feathers with the least hissing. But tax policy should aim to do more than smother protest: it should also seek to raise the most money with the least distortion to economic activity.
By this measure, Britain’s attempts to fill the fiscal gulf created by recession are a dismal failure and a lesson to cash-strapped governments everywhere. Take marginal income tax rates, announced in the British budget of April 22nd. Once national insurance is added in, effective marginal rates will climb from 31.5% to 41.5% through to 61.5% on those earning just over £100,000 ($147,000), thanks to the withdrawal of the personal tax allowance. After that, the rate will fall back to 41.5%, before rising again to 51.5% on incomes over £150,000.
