Challenge an over-assessed property value in Georgia. Generate a compliant demand letter citing O.C.G.A. § 48-5-311 with the 45-day appeal deadline.
Generate My Letter — $19If you own property in Georgia and believe your county Board of Tax Assessors has set your value too high, state law gives you a clear and time-sensitive path to fight back. Georgia property owners receive an Annual Notice of Assessment each spring, and from the date printed on that notice, the clock starts ticking. Missing the deadline can lock in an inflated value—and an inflated tax bill—for the entire year. A well-drafted challenge letter, filed as a formal appeal with your county Board of Assessors, forces the county to either justify its number with evidence or reduce it. Knowing the right statute, the correct grounds, and the proper appeal route (Board of Equalization, hearing officer, arbitration, or Superior Court) can mean the difference between paying fair taxes and overpaying for years.
Georgia property tax assessments are governed primarily by O.C.G.A. § 48-5-311, which sets out the appeal procedure, and O.C.G.A. § 48-5-7, which requires that all property be assessed at 40% of its fair market value. The county Board of Tax Assessors must mail an Annual Notice of Current Assessment to every taxpayer under O.C.G.A. § 48-5-306, and that notice must include the prior year's value, the current year's value, and an explanation of appeal rights. A taxpayer has 45 days from the date of the notice to file a written appeal. Permitted grounds include: (1) value—the assessed value exceeds fair market value; (2) uniformity—the property is assessed unfairly compared to similar properties; (3) taxability—the property should not be taxed; (4) denial of exemption; and (5) breach of covenant. Once an appeal is filed, the Board of Assessors must review it. If they decline to change the value, the appeal automatically advances to the County Board of Equalization (BOE), or, at the taxpayer's election, to a hearing officer (for non-homestead property valued over $500,000) or binding arbitration. Importantly, under O.C.G.A. § 48-5-299(c), if the value is changed on appeal, the new value generally cannot be increased by the county for the next two successive years (the "299(c) freeze"). If the taxpayer is still dissatisfied after the BOE decision, they may appeal to Superior Court within 30 days, where the case is heard de novo before a jury if requested.
A strong Georgia over-assessment challenge letter functions as the formal written appeal required by O.C.G.A. § 48-5-311(e). It must be filed with the county Board of Tax Assessors—not the Tax Commissioner—within 45 days of the assessment notice date. The letter should clearly identify the property by parcel ID and address, state the owner's opinion of fair market value, and select the appeal ground (most commonly "value" and "uniformity"). It should also designate the next-level forum: Board of Equalization (free), hearing officer, or arbitration. The most persuasive letters include supporting evidence: recent comparable sales within the same neighborhood, a recent purchase price if the property was bought near the assessment date, a fee appraisal, photographs documenting deferred maintenance or damage, contractor repair estimates, and income/expense data for rental property. Citing the 40% assessment ratio under O.C.G.A. § 48-5-7 and pointing out arithmetic or classification errors strengthens the demand. Requesting the 299(c) value freeze should be explicit. A clear, evidence-backed letter often prompts the Board of Assessors to reduce the value at the initial review stage, avoiding the need for a hearing. Even when it doesn't, the letter preserves every appeal right, locks in the 45-day filing date, and frames the record for the BOE, hearing officer, or Superior Court. Sending by certified mail or filing in person with a stamped copy is strongly recommended to prove timely filing.
The initial appeal to the Board of Assessors and the Board of Equalization is free—there is no filing fee. If the matter advances to Superior Court, the standard civil filing fee applies (varies by county, generally $200–$225). Georgia's small claims (Magistrate Court) jurisdictional limit is $15,000, but property tax assessment appeals are not heard in Magistrate Court; they follow the § 48-5-311 track. Hearing officer appeals are limited to non-homestead real property valued at more than $500,000. Arbitration requires the taxpayer to submit a certified appraisal within 45 days of filing. If the final value at the BOE or beyond is reduced by 15% or more from the original, the county may be ordered to pay the taxpayer's attorney fees and costs under O.C.G.A. § 48-5-311(g)(4)(B.1).
Property tax in Georgia is governed by the Georgia Ad Valorem Property Tax Law (assessment ratio) / Appeal of Assessment statute (O.C.G.A. § 48-5-7 (40% assessment ratio); O.C.G.A. § 48-5-311 (appeals)). Assessment cycle: Annual. Property is valued as of January 1 each year by the county Board of Tax Assessors; owners receive an Annual Notice of Assessment. Assessed value: 40% of fair market value (O.C.G.A. § 48-5-7), unless otherwise specified by law.
County Board of Tax Assessors (assessment) and County Board of Equalization / Hearing Officer / Arbitration (first-instance appeal); Georgia Department of Revenue (Local Government Services) provides statewide oversight and forms; Superior Court for judicial appeal. The window to act is short — 45 days from the date the Annual Notice of Assessment was mailed (the clock runs from the mail date, not receipt). Written appeal filed with the county Board of Tax Assessors, standard Form PT-311A.
A recent change to watch: HB 92 (effective 2025+ tax years) eliminated the automatic freeze of assessed value merely upon filing an appeal — the freeze now applies only if the taxpayer wins a value reduction. HB 581 (ratified Nov 2024, effective Jan 1, 2025) created a statewide floating homestead exemption capping primary-residence taxable-value increases to inflation, with a phased local opt-out through 2029.
How your value is assessed: 40% of fair market value (O.C.G.A. § 48-5-7), unless otherwise specified by law.
Evidence that works: Comparable sales, independent/fee appraisals, evidence of property condition or errors in the assessor's record, and documentation of uniformity with comparable assessments.
Appeal deadline: 45 days from the date the Annual Notice of Assessment was mailed (the clock runs from the mail date, not receipt). Written appeal filed with the county Board of Tax Assessors, standard Form PT-311A.
First-level appeal: Written appeal to the county Board of Tax Assessors, which reviews the appeal and notifies the taxpayer of its decision. If the Board makes no change, the appeal is automatically forwarded to the taxpayer's chosen trier of fact.
Next-level appeal: Taxpayer elects one of: County Board of Equalization (BOE); a Hearing Officer (certified appraiser, for higher-value/commercial property); or binding Arbitration. From BOE or Hearing Officer, further appeal lies to Superior Court (arbitration decisions are final).
Grounds you can raise: Value (fair market value overstated), uniformity/equalization (assessed inconsistently with comparable properties), taxability, denial of exemption, and breach/denial of covenant (O.C.G.A. § 48-5-311).
Exemptions to claim: Standard homestead exemption (owner-occupied primary residence as of January 1; commonly $2,000 off assessed value, varies by county). Senior: $4,000 from state and county taxes for age 65+, with many counties adding larger local senior exemptions. Disabled veteran: exemption of the greater of $32,500 or the federal maximum ($121,812 for 2025) for 100% service-connected veterans. HB 581 statewide floating homestead exemption (effective Jan 1, 2025) caps annual taxable-value growth on primary residences to inflation, though most large metro counties opted out.
The hearing: Administrative hearing before the Board of Equalization (three-member citizen panel), a certified appraiser Hearing Officer, or an arbitrator, depending on the taxpayer's election; de novo review available in Superior Court for BOE/Hearing Officer outcomes.
First, written appeal to the county Board of Tax Assessors, which reviews the appeal and notifies the taxpayer of its decision. If the Board makes no change, the appeal is automatically forwarded to the taxpayer's chosen trier of fact.
If that fails, taxpayer elects one of: County Board of Equalization (BOE); a Hearing Officer (certified appraiser, for higher-value/commercial property); or binding Arbitration. From BOE or Hearing Officer, further appeal lies to Superior Court (arbitration decisions are final).
Mind the deadline: 45 days from the date the Annual Notice of Assessment was mailed (the clock runs from the mail date, not receipt). Written appeal filed with the county Board of Tax Assessors, standard Form PT-311A.
