What does tax mean?
Tax is the compulsory levy imposed by a government and, by extension, the amount of money owed under that levy. As a noun, tax can refer to a specific charge, such as an income tax, or figuratively to a burdensome demand on someone’s time, energy, or resources. As a verb, tax means to impose such a charge or to place a strain on a person or system. In everyday use, the word often carries a sense of obligation or burden and can become politically charged when it concerns taxation policy. The expression is formal but widely understood in British and American English. Tax is also a useful example of how vocabulary preserves history: its Latin ancestry links an everyday governmental concept with roots meaning “to touch.” A reader encountering tax can therefore distinguish both its practical meaning as a payment owed and its broader figurative sense as a burden imposed on someone or something.
A compulsory charge imposed by a government or other authority, especially on income, goods, property, or transactions. The term may also denote the amount charged or a general financial burden.
"The new tax takes effect at the beginning of next year."
The noun is standard in formal and official contexts and is also common in general discussion of taxation and public finances.
To impose a tax on someone or something, making them liable for a compulsory payment. It can also mean to place a demanding strain on a person, organization, or system.
"Regulators warned that the proposal could tax smaller businesses too heavily."
The figurative use often emphasizes pressure, excessive demand, or strain.
The standard plural is used for individual charges, as well as for taxation considered collectively.
"Households must file their returns and pay any taxes they owe."
Tax descends from Latin taxare, “to touch or assess”—an unexpectedly physical origin for a modern financial term.

Etymology of tax
The English noun tax came through Old French taxe from Medieval Latin taxare, used for assessing or levying a payment; the English verb was borrowed from the same Latin tradition. Latin taxare is related to tangere, “to touch,” an origin also reflected in cognates such as tangent, tangible, tactile, and contact.
