Georgia Property Tax Appeal: Complete 2026 Guide

How Georgia Property Tax Assessments Work

Georgia law requires that all property be assessed at 40% of its fair market value (O.C.G.A. 48-5-7). This 40% figure is your “assessed value” — the number your property taxes are actually calculated on. So if your county says your home is worth $350,000 on the market, your assessed value would be $140,000. Your tax bill is that $140,000 multiplied by your local millage rate.

County Boards of Tax Assessors are responsible for determining your property’s fair market value. Georgia revalues properties annually, which means your assessment can change every year based on neighborhood sales, market trends, and any changes to your property. You receive an Annual Notice of Assessment each spring — typically between April and June depending on the county — showing your property’s current fair market value, assessed value, and any exemptions applied.

Why this matters for your appeal: When you appeal, you are challenging the county’s opinion of your home’s fair market value. If you can show that comparable homes have sold for less than what the county claims your home is worth, the assessed value drops proportionally. A $50,000 reduction in market value means a $20,000 reduction in assessed value (40%), which at a typical metro Atlanta millage rate of 30 mills saves about $600 per year — locked in for three years.

Georgia Appeal Deadlines

You have 45 days from the date your Annual Notice of Assessment is mailed to file an appeal with the County Board of Tax Assessors. The mailing date is printed on the notice itself. This 45-day window is strict — late appeals are not accepted.

Because Georgia counties mail notices at different times, there is no single statewide deadline. Metro Atlanta counties typically mail notices between April and June:

• Fulton County: Notices typically mailed in May–June
• DeKalb County: Notices typically mailed in May–June
• Gwinnett County: Notices typically mailed in April–May
• Cobb County: Notices typically mailed in April–May

Do not wait. The 45-day clock starts when the notice is mailed, not when you receive it. If your notice was mailed May 15, your deadline is approximately June 29 regardless of when you check your mailbox. Mark your calendar the day it arrives.

How to File Your Georgia Property Tax Appeal

Georgia offers three appeal methods. Most residential homeowners use the Board of Equalization, but you choose your method when you file.

Step 1: File with the County Board of Tax Assessors

Submit a written appeal using Georgia Form PT-311A (Appeal of Assessment) or a letter to your County Board of Tax Assessors within 45 days of the notice date. Your appeal must specify which method you prefer: Board of Equalization hearing, Hearing Officer, or nonbinding arbitration. If you don’t specify, it defaults to the Board of Equalization.

You can file by mail (postmark counts as filing date), by statutory overnight delivery, or electronically if your county accepts email appeals. Many counties including Gwinnett and DeKalb also accept appeals through their online portals. There is no filing fee for the initial appeal to the Board of Equalization.

After receiving your appeal, the Board of Tax Assessors reviews it and may offer a revised value. If you accept, the case is closed. If not, it moves to your chosen appeal body.

Step 2: Board of Equalization Hearing

The Board of Equalization (BOE) is a three-member panel of local property owners trained in tax law and appraisal. The hearing is your opportunity to present evidence. You go first, then the county appraiser presents their case. BOE members can ask questions of both sides. Hearings typically last 15–30 minutes.

Some counties, including Gwinnett, offer remote hearings via WebEx video conference as an alternative to appearing in person. Check with your county for options.

Step 3: Further Appeals

If you disagree with the BOE decision, you can appeal to Superior Court within 30 days. The Board of Tax Assessors must offer a settlement conference within 45 days of your notice of further appeal. If no settlement is reached, the case is certified to Superior Court with a $25 filing fee. You can also elect arbitration as an alternative, though this requires submitting a certified appraisal.

What Evidence Wins Georgia Property Tax Appeals

Georgia BOE panels evaluate appeals based on market value evidence. The most effective evidence falls into three categories:

1. Comparable Sales

This is the foundation of every successful Georgia appeal. Find 3–5 recent sales of similar homes in your area that sold for less than the county’s stated fair market value of your home. Focus on sales within 6–12 months prior to January 1 of the tax year (Georgia’s assessment date), in the same neighborhood or comparable location, with similar size, age, and condition.

For example, if the county values your 2,200 sq ft ranch at $375,000, but three similar homes within a mile sold for $330,000–$345,000, you have strong evidence for a reduction. The BOE will look at adjustments for differences in features, so note why each comp is comparable. See our guide to finding comparable sales.

2. Property Condition Issues

Document problems that affect your home’s market value but may not be reflected in the county’s records. Georgia’s rapid growth means assessors often rely on mass appraisal models that miss individual property conditions:

• Structural issues: Foundation problems (common with Georgia red clay soil), water damage, termite damage
• Deferred maintenance: Aging HVAC systems, roof nearing end of life, outdated plumbing
• External factors: Proximity to commercial development, traffic noise, flooding risk, power line easements
• Functional obsolescence: Unusual floor plans, small bathrooms, insufficient closet space, no garage in areas where garages are standard

3. Property Record Errors

Check your property record card on your county’s online portal. Verify the square footage, lot size, bedroom and bathroom count, year built, and any noted improvements. Georgia’s fast-growing suburban counties process thousands of permits and sales annually, and recording errors do happen. If the county shows a finished basement that’s actually unfinished, or lists 2,400 sq ft when you have 2,100, that error alone may justify a significant reduction.

The Board of Equalization Hearing Process

After filing, here’s what to expect at your BOE hearing:

1. Board of Assessors review: After receiving your PT-311A, the assessors review your property and may offer a revised value before your hearing is scheduled
2. Hearing notice: If the case proceeds, you receive a date and time for your BOE hearing
3. Present your case: Bring copies of comparable sales, photos, and documentation. You present first
4. County appraiser responds: The county presents their evidence and methodology
5. Board decision: The BOE issues a written decision, typically at the conclusion of the hearing or shortly after

Key Georgia hearing tip: Request a copy of the county’s comparable sales and methodology before your hearing. Georgia law requires the Board of Tax Assessors to provide copies of public records and their methodology within 10 business days of your request. Knowing what evidence the county plans to present lets you prepare targeted rebuttals.

Georgia Property Tax Appeal Statistics

Key numbers for Georgia homeowners considering an appeal:

• Assessment ratio: 40% of fair market value
• Effective tax rate: 0.90% (varies significantly by county — metro Atlanta counties are higher)
• Average annual tax bill: $2,241
• Median home value: $249,000
• Three-year value freeze: A successful appeal locks in the reduced value for the current year plus two additional years
• Settlement rate: In Gwinnett County, approximately 43% of appeals are settled or withdrawn before the hearing stage, often resulting in reduced assessments

The three-year freeze is Georgia’s most powerful appeal incentive. If you win a $30,000 reduction in market value, that saves approximately $270 per year at a 0.90% effective rate — totaling $810 over three years from a single appeal. In higher-tax metro Atlanta counties, the savings are larger.

County-by-County Appeal Guide

Georgia has 159 counties, each with its own Board of Tax Assessors and Board of Equalization. Here are the metro Atlanta counties where AppealDesk customers most frequently find overassessments:

Fulton County (Atlanta)

Fulton County spans Atlanta’s core and its affluent northern suburbs including Sandy Springs, Roswell, Alpharetta, and Johns Creek. The county’s wide range of property values — from urban condos to $1M+ homes in North Fulton — creates frequent assessment mismatches, especially in neighborhoods where values have shifted since the last round of sales data the county used. Fulton is Georgia’s most-appealed county by volume. Fulton County appeal details →

DeKalb County (Decatur, Brookhaven)

DeKalb County includes established communities like Decatur and Brookhaven alongside rapidly developing areas. The county’s mix of gentrifying neighborhoods and stable suburban pockets means mass appraisal models can overshoot in areas where sales data is thin. DeKalb’s Board of Equalization panels are trained local property owners who hear evidence at the county administration building. DeKalb County appeal details →

Gwinnett County (Lawrenceville, Duluth, Suwanee)

Gwinnett is one of Georgia’s fastest-growing counties, which means rapid development and rising assessments. However, growth is uneven — some neighborhoods plateau while new construction nearby drives the county’s model higher. Gwinnett offers WebEx remote hearings as an alternative to in-person appearances, making it one of the most accessible counties for appeals. Gwinnett County appeal details →

Cobb County (Marietta, Kennesaw, Smyrna)

Cobb County’s proximity to the Braves stadium and ongoing commercial development has driven significant value shifts in surrounding neighborhoods. Homeowners in areas like East Cobb, where established homes compete with new construction, often find the county’s model doesn’t adequately account for age-related depreciation.

Georgia Property Tax Exemptions and Relief Programs

Beyond appealing your assessed value, make sure you are claiming every exemption you qualify for. Georgia offers several:

Standard Homestead Exemption

Georgia’s basic homestead exemption reduces the assessed value of your primary residence for school tax purposes. The state exemption is $2,000 off the assessed value for state and county taxes, but many counties and cities offer additional local homestead exemptions that can be substantially more generous. Apply by April 1 through your county tax assessor’s office.

Senior Exemptions

Georgia offers multiple senior exemptions depending on your county and income. Homeowners 65 and older may qualify for exemptions on school taxes if their household income falls below certain thresholds. Some metro Atlanta counties — including Fulton and Gwinnett — offer enhanced local senior exemptions that can save hundreds per year. Check your county’s specific programs.

Veteran and Disability Exemptions

Veterans with a VA-rated disability can receive additional exemptions. The amount varies by disability rating and county. Unremarried surviving spouses and minor children of deceased veterans may also qualify. Apply through your county tax assessor with your VA benefits letter.
