Etymology

Origin of tax

First recorded in 1250–1300; (for the verb) Middle English taxen, from Medieval Latin taxāre, from Latin: “to appraise, charge, estimate,” literally, “to touch repeatedly,” from tangere “to touch”; noun derivative of the verb

Explanation

A charge or fee that a government imposes on a citizen or business is called a tax. Taxes help to pay for the services people (and businesses) receive from the government. There are many different kinds of taxes—on purchases, property, and income, for example—but all tax money is meant to pay for things that benefit people in society. For example, in many places schools, road repairs, fire departments, and health care for elderly and disabled people are all paid for with money from taxes. As a verb, tax can either mean "impose a tax on" or "put a strain or burden on."
