The word comes from the Latin for 'to touch,' as in to assess by handling.
The word "tax" entered English in the early fourteenth century from the Old French taxer, meaning to impose a levy or to assess a charge. The French word derived from the Latin taxare, meaning to evaluate, to appraise, or to handle, an intensive form of tangere, meaning to touch.1 A tax, in its deepest etymological sense, is what happens when the state reaches out and touches your property.
Taxation predates the word by thousands of years. The earliest known tax records are clay tablets from ancient Sumer, dating to around 3000 BC, documenting levies on grain and livestock.2 In ancient Egypt, scribes assessed taxes on cooking oil, grain, and property, with collectors making regular rounds. The Rosetta Stone, carved in 196 BC, records a tax decree issued by the priests of Memphis on behalf of Ptolemy V.3
England's Domesday Book, compiled in 1086 by order of William the Conqueror, was a comprehensive survey of landholdings and assets across the kingdom, created explicitly to determine what taxes were owed and by whom.4 The name "Domesday" (Day of Judgment) reflected the finality of its assessments, against which there was no appeal.
The modern income tax was introduced in Britain by William Pitt the Younger in 1799 to fund the Napoleonic Wars, levied at a rate of two shillings per pound (10%) on incomes above sixty pounds per year.5 The United States adopted a federal income tax during the Civil War in 1861, repealed it in 1872, and permanently established it through the Sixteenth Amendment in 1913.6
