Are Property Taxes Based on Market Value or Appraised Value?

Property taxes represent a significant financial obligation for property owners and serve as a primary revenue stream for local governments, funding essential public services such as schools, police, and infrastructure. These taxes are typically calculated based on a property’s value. However, confusion often arises regarding whether property taxes are determined by a property’s “market value” or its “appraised value.”

What is Market Value

Market value is the most probable price a property would command in an open and competitive market. This price assumes that both the buyer and seller are well-informed, acting prudently, and are not under any undue pressure to buy or sell. It represents an estimate of what a property could realistically sell for at a given time.

Various factors influence a property’s market value, including its location, overall condition, and the characteristics of the neighborhood. Recent sales data of comparable properties in the area are also a strong determinant of market value. Economic conditions, such as interest rates and the general supply and demand for housing, cause market value to be a dynamic figure that fluctuates over time.

What is Appraised Value

Appraised value, in the context of property taxation, is the value assigned to a property by the local tax assessor’s office for the purpose of calculating property taxes. While this value is derived from market value, it often differs from the current market value. The divergence occurs for several reasons, reflecting the practicalities and regulations of property assessment.

Tax assessors typically utilize mass appraisal techniques rather than individual appraisals for every property, meaning values can lag behind rapid market changes. Properties are also often appraised on a cyclical basis, such as every few years, which means the appraised value may not always reflect the most recent market fluctuations. Furthermore, many jurisdictions have regulations that limit how much an appraised value can increase in a given year, such as assessment caps or homestead exemptions, creating a further difference from true market value. In some areas, an “assessed value” is used, which is a percentage of the appraised value, serving as the final tax base.

The Property Assessment Process

Local tax assessors are responsible for determining the appraised value of properties within their jurisdiction. They employ standardized methods to ensure fairness and consistency across all properties. This process involves collecting and analyzing a wide array of data points for each property.

Assessors consider property characteristics such as size, age, number of rooms, land area, and construction quality. Revaluation cycles, which typically occur every one to eight years, dictate when a property’s appraised value is updated. However, some jurisdictions may update values annually, particularly for properties with physical changes like new construction or significant renovations.

Calculating Your Property Tax

Property tax bills are directly calculated using the property’s appraised value, or the assessed value derived from it, rather than its current market value. The basic formula for determining your property tax bill is the appraised or assessed value multiplied by the tax rate. This tax rate, often expressed in “mills” or as a percentage, is set by local taxing authorities such as county, city, and school districts.

One mill represents one-tenth of one cent, or $1 for every $1,000 of assessed property value. Local governments establish these tax rates annually to generate the necessary revenue for public services.
