tax

v. impose a tariff, impose a levy; burden, demand too much

n. levy, fee

A tax is a financial charge or other levy imposed on an individual or a legal entity by a state or a functional equivalent of a state (for example, secessionist movements or revolutionary movements). Taxes could also be imposed by a subnational entity. Taxes consist of direct tax or indirect tax, and may be paid in money or as unpaid labour. A tax may be defined as a "pecuniary burden laid upon individuals or property to support the government […] a payment exacted by legislative authority." A tax "is not a voluntary payment or donation, but an enforced contribution, exacted pursuant to legislative authority" and is "any contribution imposed by government […] whether under the name of toll, tribute, tallage, gabel, impost, duty, custom, excise, subsidy, aid, supply, or other name."
