Definition:

Overview:
The legal definition and the economic definition of taxes differ in that economists do not consider many transfers to governments to be taxes. For example, some transfers to the public sector are comparable to prices. Examples include tuition at public universities and fees for utilities provided by local governments. Governments also obtain resources by creating money (e.g., printing bills and minting coins), through voluntary gifts (e.g., contributions to public universities and museums), by imposing penalties (e.g., traffic fines), by borrowing, and by confiscating wealth. From the view of economists, a tax is a non-penal, yet compulsory transfer of resources from the private to the public sector levied on a basis of predetermined criteria and without reference to specific benefit received.
In modern taxation systems, taxes are levied in money; but, in-kind and corvée taxation is characteristic of traditional or pre-capitalist states and their functional equivalents. The method of taxation and the government expenditure of taxes raised are often highly debated in politics and economics. When taxes are not fully paid, civil penalties (such as fines or forfeiture) or criminal penalties (such as incarceration) may be imposed on the non-paying entity or individual.
Purpose of Taxes:
The purpose of taxation is to finance government expenditure. One of the most important uses of taxes is to finance public goods and services, such as street lighting and street cleaning. Since public goods and services do not allow a non-payer to be excluded, or allow exclusion by a consumer, there cannot be a market in the good or service, and so they need to be
