Tax Rate Details
Understanding Millage Rates in Cobb County
In Georgia, 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 Georgia, property is assessed at 40% of fair market value. The millage rate is applied to this assessed value, so a home worth $300,000 has an assessed value of $120,000 for tax purposes. Georgia counties, cities, and school districts each set their own millage rates.
Cobb County has an effective property tax rate of 0.69%, resulting in a median annual tax bill of $2,560. Use the calculator above to estimate your property tax based on Cobb County's current rate, or contact the Cobb County tax assessor's office for the exact millage rate breakdown for your property.
