Georgia Property Value Estimator
See how a Georgia property's fair market value becomes its assessed value at the 40% ratio, apply the state standard homestead exemption, and estimate the property tax that follows.
This is an estimate, not an appraisal. The tool does not value your property; it works through Georgia’s value chain from a figure you supply. It is not an official assessment, tax bill, or professional valuation.

Georgia rules apply. This tool works through Georgia’s value chain only — a different state’s ratios, exemptions and rates do not apply here.

How the Georgia estimate is calculated
The estimator applies Georgia’s verified value chain to the value you enter: the figures that convert a market value into the taxable value the rates apply to, using the state’s own assessment ratio, exemption amounts and cap mechanics. The state does not supply rates — rates are local — so the optional tax estimate uses the rate from your own bill. Every rule number is cited below and was verified from the official source listed.
Limitations
- This is not an appraisal: the fair market value you enter is assumed, not estimated by the tool.
- Only the $2,000 state standard exemption is computed. County homestead exemptions, local option exemptions and valuation freezes can be worth far more and vary by county.
- The tax estimate is only as good as the combined millage you supply; millage is adopted separately by the county board of commissioners, school board and any city.
- Fees imposed at 85% of the appeal-stage value and other county-specific charges are not modeled.
Frequently asked questions
- How does Georgia calculate property taxes?
- The county board of tax assessors values property at fair market value as of January 1 each year, and the taxable base is 40% of that figure. Millage rates set by the county, school board and cities are applied to the assessed value minus exemptions.
- What is the 40% assessment ratio?
- Georgia law taxes 40% of fair market value, so a $300,000 home carries an assessed value of $120,000. The homestead exemption is deducted from that assessed figure, not from market value.
- Why can my actual tax bill be different?
- Your county may offer exemptions worth much more than the state standard, or a local valuation freeze that holds your assessment at an old base year. Your combined millage figure may also differ from what each authority adopted.
- Is this an appraisal?
- No. Official values come from your county board of tax assessors, appeals are filed with them within 45 days of the annual notice, and the tax commissioner bills and collects.
