Legal and real world aspects

In many political systems, the government requests that owners pay for the privilege of ownership. A property tax is an ad valorem tax on the value of a property, usually levied on real estate. The tax is levied by the governing authority of the jurisdiction in which the property is located. It may be imposed annually or at the time of a real estate transaction, such as in real estate transfer tax. Under a property-tax system, the government requires or performs an appraisal of the monetary value of each property, and tax is assessed in proportion to that value. The four broad types of property taxes are land, improvements to land (immovable human-made objects, such as buildings), personal property (movable human-made objects), and intangible property.
