Georgia Property Tax Assessment: How Is Your Home Valued?

Georgia taxes most residential property based on an assessed value tied to fair market value. For many homes, the assessed value equals 40% of fair market value. Millage rates are then applied to that assessed amount—not to your full home price.

How counties estimate fair market value

Mass appraisal models blend recent sales, neighborhood trends, building characteristics, and sometimes aerial or field review. Models lag fast-moving markets, which is why new sales nearby are persuasive appeal evidence.

Millage in plain English

Millage is tax per $1,000 of assessed value. A rate of 40 mills implies roughly $40 per $1,000—or $400 on $10,000 of assessed value. Your bill combines county, school, and other levies.

Estimating your tax bill

Multiply assessed value × total millage (expressed in dollars per thousand). Even a modest assessed-value reduction can yield meaningful annual savings when rates are stacked across jurisdictions.

Common overassessment signals

Recent purchases below notice value, stagnant condition while the model assumes updates, or a cluster of lower closed sales on your street all suggest the notice may be high.
