How it works
Property in Cobb County is valued at fair market value by the county Board of Tax Assessors. For taxation, Georgia applies a uniform assessment ratio, producing a taxable assessed value before exemptions. Local governments adopt millage rates, and the combined local millage rate is applied to the taxable assessed value to estimate the annual property tax.
Examples
If a property has a market value and the applicable assessment ratio is applied, the resulting assessed value is then multiplied by the combined local millage rate. Because millage can include county, school, city, and special district components, the estimated result depends on the rate entered.
Limitations and important notes
The figures shown here represent a non-official estimate derived from user-entered data. Actual property tax bills may differ due to jurisdiction-specific millage rates, voter-approved levies, special districts, and eligibility-based exemptions such as homestead provisions. Parcel-specific assessments, exemptions, and taxing districts applied by the local assessor in Cobb County, Georgia may affect the final property tax amount and are not fully reflected in this estimate.
