Britain Invents Income Tax: War Against Napoleon
William Pitt the Younger was desperate. Britain was fighting revolutionary France, the treasury was hemorrhaging gold, and traditional taxes on windows, servants, and carriages could not cover the costs of naval warfare across three oceans. His solution was breathtakingly simple: tax income directly. The 1799 Income Tax Act levied two shillings per pound on incomes over sixty pounds, with graduated rates below that threshold. The public hated it. Merchants falsified their books. Farmers hid livestock. Pitt collected barely half of what he projected. When the war paused with the Treaty of Amiens in 1802, the tax was immediately repealed and all records destroyed. But it returned the following year when Napoleon threatened invasion again. This supposedly temporary wartime measure has never been permanently abolished in Britain, and every modern income tax system traces its DNA to Pitt's desperate gamble.
