Understanding Millage Rates in Union County
In Florida, property taxes are expressed as a millage rate (also called a mill rate). One mill equals $1 of tax for every $1,000 of assessed property value. Your total property tax bill is determined by adding together the millage rates set by the county, city or municipality, school district, and any special districts.
In Florida, property is assessed at just value (market value), but homestead exemptions can reduce taxable value by $50,000 or more. The millage rate is applied to the taxable value after exemptions. Florida counties, cities, school districts, and special districts each levy their own millage rates.
Union County has an effective property tax rate of 0.58%, resulting in a median annual tax bill of $931. Use the calculator above to estimate your property tax based on Union County's current rate, or contact the Union County tax assessor's office for the exact millage rate breakdown for your property.
