Georgia Property Tax Appeal | 2026 Guide

The Annual Notice of Assessment is the single most important document in the Georgia appeal process — it is both your notice of value and the trigger for your appeal rights. It is issued by the county Board of Tax Assessors and described in the Georgia DOR property tax materials.

What it shows:

• Fair market value (FMV) — the assessor's opinion of what your property would sell for, the number you appeal.
• Assessed value — FMV × 40%, the figure taxes are calculated on.
• The prior year's values, so you can see the change.
• An estimate of the current year's tax based on the prior year's millage rates (Georgia requires this estimate on the notice).
• The last date to file an appeal — typically the mail date plus 45 days.

What to check immediately: 1. The mail date. Your 45-day deadline runs from this date, not the date you opened the envelope. Calendar the 45th day now. 2. The fair market value vs. reality. Compare it to recent comparable sales and to similar neighbors' assessments. A jump well above market or above comparable homes signals an appeal. 3. Property characteristics. The notice (and the linked property record) lists square footage, bedrooms, baths, and lot size. Errors here — phantom rooms, overstated square footage — are objective, high-success correction grounds. 4. Exemption status. Confirm your homestead and any HB 581 floating homestead exemption are reflected; a wrongly denied exemption is itself an appeal ground.

Why timing is everything. The notice is the only window most homeowners get. Once 45 days pass, the current-year value is generally locked except for clerical-error corrections. So the moment your notice arrives: read the mail date, verify the value and the property facts, and decide whether to file Form PT-311A. Filing also preserves the three-year freeze if you carry the appeal to a decision.

A Georgia appeal requires two decisions on Form PT-311A: what you are disputing and who decides it.

Grounds (what you dispute). Under O.C.G.A. § 48-5-311, an appeal may be based on:

• Value — the fair market value is too high.
• Uniformity — your property is assessed higher than comparable properties (an equity argument, powerful in appreciating markets where pure value arguments fail).
• Taxability — the property should not be taxed at all.
• Denial of homestead exemption — the assessor wrongly denied an exemption you qualify for.

The Georgia DOR appeals guidance confirms all four grounds and lets you raise more than one.

Method (who decides). You elect one trier of fact at filing: 1. County Board of Equalization (BOE) — a panel of three trained county property owners; free; preserves a further appeal to superior court. This is the default and most common choice. 2. Hearing officer — a state-certified appraiser; available for non-homestead real property and wireless personal property valued at $500,000 or more. Decides value and uniformity only. 3. Arbitration — a binding (or, by election, nonbinding) process before a certified appraiser; the taxpayer and county each may bear costs depending on the outcome.

How to choose. Pick the BOE if you want a free hearing and the safety of a superior-court backstop — right for most homeowners. Pick a hearing officer only if your property clears the $500,000 non-homestead threshold and you want a single appraiser rather than a lay panel. Pick arbitration when you have a strong independent appraisal and want a faster, appraiser-driven decision, accepting that arbitration without a superior-court appeal is final.

Whichever you choose, the county first reviews your appeal and may offer a change; only if you reject or it stands does it move to your elected trier.

Georgia gives you three triers of fact under O.C.G.A. § 48-5-311. The right choice depends on your property type, evidence, and appetite for finality.

Board of Equalization (BOE).

• Panel of three county property owners trained by the Georgia Department of Revenue.
• Hears value, uniformity, taxability, and exemption-denial appeals.
• Free to the taxpayer.
• Decision can be appealed to superior court within 30 days — the most important safety valve.
• Best for: nearly all homeowners. Lay panel, no cost, full appeal rights preserved.

Hearing officer.

• A state-certified or licensed appraiser, available for non-homestead real property and wireless personal property valued at $500,000 or more.
• Decides value and uniformity only (not taxability or exemptions).
• Decision can still be appealed to superior court.
• Best for: higher-value non-homestead property where you prefer an appraiser's judgment over a lay panel.

Arbitration.

• A certified appraiser arbitrator decides value. The taxpayer must submit a certified appraisal; the county may accept it or proceed to a hearing.
• Cost allocation depends on the outcome: if the final value is closer to the taxpayer's appraisal, the county bears the arbitrator's fee; if closer to the county's, the taxpayer does.
• Binding when elected without a superior-court appeal — there is no court backstop on that path.
• Best for: owners with a strong independent appraisal who want a fast, appraiser-to-appraiser resolution and accept finality.

Bottom line. If you are a residential homeowner doing this yourself, choose the BOE: it costs nothing, hears every ground, and keeps the courthouse door open. Reserve the hearing officer for $500,000+ non-homestead parcels and arbitration for cases anchored by a paid appraisal. Confirm method availability on your county Board of Tax Assessors page before filing.

Unlike most states, Georgia is one where an appeal can result in a higher value. When you appeal under O.C.G.A. § 48-5-311, the trier of fact — Board of Equalization, hearing officer, or arbitrator — weighs the evidence both parties present and may set the fair market value above, below, or at the noticed value. The board is charged with finding the correct fair market value, not merely confirming or lowering the assessor's number.

How much is the real-world risk? For a typical residential homeowner with a defensible opinion of value and comparable sales, the practical risk of an increase is modest — the county must present evidence supporting a higher number, and an arbitrary increase would itself be appealable. The risk is highest when:

• Your evidence is weak or inconsistent, inviting the county to argue the assessment is actually too low.
• Recent comparable sales in your area clearly exceed your assessed value.
• You file on a strong-market property without solid support.

The offsetting upside — the three-year freeze. Even in Georgia, the calculus favors prepared appellants because a value established through a formal appeal decision is frozen for three years under O.C.G.A. § 48-5-299(c). So a well-supported appeal both protects against a near-term reassessment spike and rarely produces an increase.

How to protect yourself: 1. Gather solid comparable sales and condition evidence before filing — do not appeal on a hunch. 2. Consider the uniformity ground (your home assessed higher than similar neighbors), which is hard for the county to counter with an increase. 3. If your evidence is thin, reconsider whether to push to a formal hearing.

Bottom line: Georgia appeals are worth filing when your evidence is strong, but the upward-adjustment risk is real and you should not file blind. This is the opposite of states like Texas, where a homeowner appeal cannot raise the value.

Conservation Use Valuation Assessment (CUVA) is a preferential assessment program under O.C.G.A. § 48-5-7.4. It is most relevant to homeowners who also own qualifying farm, forest, or environmentally sensitive land — and it occasionally overlaps with assessment-appeal questions when an owner believes their land should be valued under CUVA.

What CUVA does. Instead of being assessed at 40% of fair market value, qualifying land is valued at its current-use (conservation) value, which is typically far lower than market value for land under development pressure. This produces a substantially smaller assessed value and tax bill on the covered acreage.

Eligibility and limits:

• The land must be in bona-fide agricultural or forest production, or be environmentally sensitive land.
• Up to 2,000 acres per owner may be entered into CUVA.
• There is no strict minimum acreage, but owners of fewer than 10 acres must supply extra documentation showing the primary use is bona-fide agricultural or timber production.

The covenant. CUVA requires a sworn 10-year covenant running from January 1 of the entry year, committing the owner to maintain the qualifying use. This is the trade-off for the lower valuation.

Breach penalties are steep. An owner who breaches the covenant — by developing or converting the land before the 10 years end — must pay back twice the tax savings received over the life of the covenant up to the breach, plus interest. Treat CUVA as a long-term commitment, not a one-year tax tactic.

How it relates to appeals. CUVA is an application, not an assessment appeal, but if the assessor denies or revokes your CUVA status, that denial can be challenged through the standard appeal process under O.C.G.A. § 48-5-311. For the application itself, contact your county Board of Tax Assessors; CUVA applications are due by the same deadline as a property tax return for the year. Verify acreage rules and current covenant forms on your county assessor's page before applying.

The four most-populous metro Atlanta counties handle the bulk of Georgia residential appeals. All four operate under the same statewide rules — the 45-day deadline, Form PT-311A, the value/uniformity/taxability/exemption grounds, and the Board of Equalization / hearing officer / arbitration election under O.C.G.A. § 48-5-311. What differs is the county Board of Tax Assessors office, online portal, and notice mailing calendar.

Fulton County — Fulton County Board of Assessors handles Atlanta and north/south Fulton. It offers online appeal filing through its assessor site and holds Boards of Equalization through the Superior Court Clerk. Fulton typically mails annual notices in spring; the 45 days run from that mail date.

Gwinnett County — The Gwinnett County Tax Assessor's Office provides online appeal submission and a property search portal. Gwinnett's Board of Equalization is administered through the county's court system.

DeKalb County — The DeKalb County Property Appraisal Department issues annual notices and accepts appeals online and by mail; the county Board of Equalization hears unresolved appeals.

Cobb County — The Cobb County Board of Tax Assessors runs its own portal; Boards of Equalization are administered by the Cobb County Superior Court Clerk.

What is identical in all four:

• File within 45 days of the notice mail date.
• Use Form PT-311A or a written appeal stating your method and opinion of value.
• Election of BOE (free, preserves superior-court appeal), hearing officer ($500K+ non-homestead), or arbitration.
• A formal appeal decision triggers the three-year freeze under O.C.G.A. § 48-5-299(c).
• HB 581 floating homestead applies only if your specific county, city, and school district did not opt out.

Action step: find your county's Board of Tax Assessors page (search "[county] GA board of tax assessors"), confirm the notice mail date on your assessment, and file on that county's portal before the 45th day. Always verify the current portal URL — county assessor portals are re-platformed periodically.

House Bill 581, signed April 18 2024 and ratified by voters in November 2024, created a new statewide floating homestead exemption effective January 1 2025, codified at O.C.G.A. § 48-5-44.2.

What it does. For an eligible homestead, the exemption is the difference between the property's current fair market value and an adjusted base-year value. The base-year value can rise each year only by an inflation (CPI) rate set by the State Revenue Commissioner, not by the full market increase. In effect, it caps how fast the taxable value of your home can grow.

• The base for the 2025 digest year is the 2024 assessed value; no inflation index applied for 2025.
• The first inflation index rate under HB 581 applies for the 2026 digest year.
• Example from the DOR: a $300,000 base value with 2% CPI becomes a $306,000 adjusted base year value.

The big catch — opt-outs. HB 581 let counties, cities, and school districts opt out of the floating exemption by following an advertise-and-resolve process, with an early deadline in March 2025. A number of jurisdictions (for example, several school districts and counties) opted out, so the exemption does not apply uniformly across Georgia. Check whether your specific county, city, and school district adopted it before relying on the cap.

How it interacts with your appeal. HB 581 caps the taxable value growth, but your fair market value can still rise on the Annual Notice of Assessment — and FMV is what drives uniformity comparisons and the 40% assessed value. So:

• You may still appeal your fair market value even if the floating exemption limits this year's taxable increase.
• Lowering FMV through appeal can lower or reset your base-year value, compounding the cap's benefit going forward.
• The exemption does not replace the three-year freeze you earn by appealing — both can operate together.

Confirm your jurisdiction's opt-in/opt-out status with your county Board of Tax Assessors and the DOR overview before assuming the cap protects you.

In Georgia, the right to appeal opens when the county Board of Tax Assessors mails your Annual Notice of Assessment, and it closes 45 days from the date that notice was mailed. The deadline is governed by O.C.G.A. § 48-5-311(e), which directs that an appeal be effected by mailing, emailing, or filing a notice of appeal with the county board of tax assessors within that 45-day window.

Use Form PT-311A. Georgia provides a uniform statewide appeal form, the PT-311A Appeal of Assessment Form, accepted in every county. You are not required to use the form — a signed letter stating your election of appeal method and your opinion of value also works — but the form prompts you for everything the board needs. The Department of Revenue is explicit that you file with the county board of tax assessors, not the Department of Revenue.

The 45 days run from the mailing date, not the date you receive it. Look for the mail date printed on the notice itself. If the 45th day falls on a weekend or legal holiday, the deadline rolls to the next business day. Counties typically mail notices between April and June, so most appeal windows close between June and August.

What to include in a timely appeal: your parcel identification, the value you are disputing, your opinion of value, and your chosen method of appeal (Board of Equalization, hearing officer, or arbitration — see the related question on method election). Filing on time also preserves your right to the three-year value freeze under O.C.G.A. § 48-5-299(c).

Missing the deadline is usually fatal for the current year. Unlike a few states with broad good-cause late filing, Georgia's 45-day window is strictly applied. If you miss it, your remaining options are limited to correcting clerical errors or filing a fresh appeal next year. File early — the moment your notice arrives, calendar the 45th day.

Superior court is the judicial backstop in Georgia's appeal ladder, available after a Board of Equalization or hearing officer decision under O.C.G.A. § 48-5-311.

The escalation path. 1. County review / settlement conference — assessors review and may settle. 2. Board of Equalization, hearing officer, or arbitration — your elected trier decides. 3. Superior court — judicial appeal of a BOE or hearing officer decision.

How to appeal to superior court. File a written notice of appeal with the county board of tax assessors within 30 days of the date the BOE or hearing officer decision is mailed. The board then certifies the appeal to the clerk of superior court. Key features:

• The case is heard de novo — the court considers the value fresh, not merely whether the board erred.
• You may be entitled to a jury trial on value.
• Filing fees apply at the superior-court level (set locally; confirm with the clerk).

Cost and fee-shifting considerations. Superior-court appeals carry real costs (filing fees, often an appraiser, sometimes counsel). Georgia law contains provisions that can shift some costs or interest depending on how the final value compares to the parties' positions, so a strong, well-documented opinion of value matters. For most residential homeowners, the Board of Equalization plus the settlement conference resolve the case; superior court is worth it mainly for larger disputes or clear board error.

Important limit. If you elected arbitration without a superior-court appeal, that path is final — you generally cannot then go to superior court. This is why the BOE route, which preserves the court appeal, is the safer default for homeowners who want to keep their options open.

Confirm the 30-day deadline and local filing fees with your county board of tax assessors and the superior court clerk before proceeding.

Uniformity is one of the four statutory grounds for a Georgia appeal under O.C.G.A. § 48-5-311, alongside value, taxability, and exemption denial. It is the strongest tool in an appreciating market, where arguing your home is worth less than the assessment is hard but proving it is taxed unequally is not.

The principle. Georgia's constitution and tax code require that property be assessed uniformly — similar properties should carry similar assessed values. Because every parcel is assessed at the same 40% ratio, if comparable homes in your neighborhood are assessed at lower fair market values per square foot than yours, your assessment is not uniform — even if your value alone might be defensible. The board of tax assessors is statutorily charged with seeing that values are "fairly and justly equalized" among taxpayers.

How to build the argument: 1. Identify true comparables — homes genuinely similar to yours in size, age, condition, lot, and location (ideally the same subdivision or street). 2. Pull their assessed (40%) values from the county assessor's public property search. 3. Normalize — compare assessed value per square foot. If similar homes are assessed at $120/sf and yours at $150/sf, that gap is your uniformity case. 4. Present a schedule of 5+ comparable assessments showing your property is the outlier on the high side.

Why uniformity wins where value loses. In a hot market, recent sales may support a high market value, undercutting a pure value appeal. But the assessor still must assess equally — so even a correctly-valued home can be reduced if neighbors are under-assessed. This makes uniformity the go-to ground for well-located homes in rising markets.

Caution. Because Georgia boards can adjust value upward, choose comparables carefully — weak or cherry-picked comps can backfire. Use genuinely similar properties and present them cleanly. You can raise uniformity and value together on Form PT-311A, giving the board two independent paths to a reduction.
