How Georgia assessment appeals generally work (state framework reviewed 2026-08-02 from official Georgia sources): County Boards of Tax Assessors determine fair market value as of January 1. Taxable tangible property is generally assessed at 40% of fair market value, while preferential agricultural, conservation-use, forest-land, historic, and other special programs can use different percentages or valuation standards. A property owner files with the County Board of Tax Assessors and selects an authorized route: County Board of Equalization, hearing officer when eligible, or arbitration. A party dissatisfied with the resulting decision may appeal to the Superior Court under the statutory procedure.
Georgia deadline framework: The initial appeal must be filed with the County Board of Tax Assessors within 45 days of the annual assessment notice date. The selected Board of Equalization, hearing-officer, or arbitration route has additional response, appraisal, and hearing deadlines. A Superior Court appeal is generally due within 30 days after the lower decision is mailed, subject to the actual decision and current statute.
Local variation in Georgia: Georgia's 159 county Boards of Tax Assessors administer notices, records, filing portals, reviews, and local calendars. The chosen appeal route materially changes eligibility, documentation, costs, and procedure. Municipal boundaries spanning counties and special valuation programs require additional authority checks.
Before relying on a date: Resolve the county, January 1 facts, tax year, assessment-notice date, property and special-program classification, and intended appeal route, then verify the county's PT-311A filing channel, exact receipt deadline, Board of Tax Assessors response, route-specific requirements, decision mailing date, and any Superior Court filing prerequisites.
