Property Tax: Definition, What It's Used for, and How It's Calculated

What Is Property Tax?

A property tax is an annual or semiannual charge levied by a local government and paid by the owners of real estate within its jurisdiction. Property tax is an ad-valorem tax, meaning the amount owed is a percentage of the assessed value of the real estate.

Property tax receipts are the main source of revenue for most local governments in the U.S. They are used to fund schools, police and fire departments, road construction and repair, libraries, water and sewer departments, and other local services that benefit the community. 

In common usage, property tax refers to a tax on immovable possessions like structures or land. Some local jurisdictions also assess property taxes on moveable property such as vehicles and industrial equipment.

Understanding Property Tax

Property tax is paid by individuals or legal entities such as corporations that own the property.

It is characterized as a regressive tax. That is, the same rate of taxation is applied regardless of the taxpayer's income. The burden falls disproportionately on lower-income taxpayers.

The tax is usually based on the value of the owned property, including land and structures. Many jurisdictions also tax tangible personal property, such as cars and boats. Property tax rates and the types of properties taxed vary by jurisdiction.

In most Organization for Economic Co-operation and Development (OECD) countries, immovable property tax represents a low proportion of federal revenue when compared to income taxes and value-added taxes.

The average rate in the United States is substantially higher than in many European countries. Many empiricists and pundits have called for an increase in property tax rates in developed economies. They argue that the predictability and market-correcting character of the tax encourage stability.

Calculating Property Tax

The amount owners owe in property tax is determined by multiplying the property tax rate by the current market value of the property. Most taxing authorities recalculate the tax rate annually. 

Almost all property taxes are levied on real property, which is legally defined and classified by the state. Real property generally includes land, structures, and other fixed buildings.

Ultimately, property owners are subject to the rates determined by the municipal government. The municipality appoints or elects a tax assessor who evaluates local property and calculates property taxes based on current fair market values. This value becomes the assessed value of the home.

In almost all local property tax codes, the owner has the right to formally contest the rate assessed. When property taxes are unpaid, the taxing authority may assign a lien against the property.

Property Tax vs. Real Estate Tax

People often use the terms property tax and real estate tax interchangeably. In fact, not all property taxes are real estate taxes.

Many jurisdictions also levy property taxes against tangible personal property. According to a report by the Tax Foundation, 43 states tax tangible personal property.

Both types of property can be deducted from federal taxes. However, since the Tax Cuts and Jobs Act of 2017, the deduction has been capped at $10,000 per year for married couples and single taxpayers.

So here's the difference: Real estate taxes are taxes on real property only; property taxes can include both real property and tangible personal property.

The Bottom Line

Property tax is defined by the Tax Foundation as the tax that is imposed on immovable property like land and buildings, as well as on movable property, like vehicles and equipment.

Property tax is the single largest source of state and local revenue in the U.S. The capital is used to fund schools, roads, police, and other services. Property tax rates vary greatly among states and localities.
