Assessment Ratio

An assessment ratio is the percentage of a property's market value that a state uses as the assessed value for tax purposes, such as Georgia's 40% ratio set by O.C.G.A. 48-5-7.

States do not all tax the full market value of property. Georgia assesses most property at 40% of fair market value, so a building the county values at five million dollars carries an assessed value of two million, and the millage rates apply to that number. Florida applies its rates to taxable value after caps and exemptions, and California's assessed value is generally the Proposition 13 factored base year value rather than a ratio of current market value.

The practical point for owners is to appeal the right number. In a ratio state, the assessed value moves mechanically with the market value the county assigned, so the appeal targets the underlying market value, not the ratio.
