Georgia Property Tax Appeal Deadlines: What to Know Before Time Runs Out

Key Takeaways

• Georgia homeowners have exactly 45 days from the date on their assessment notice to file an appeal, and there are no extensions.

• 2026 filing deadlines range from June 29 (Gwinnett) to August 14 (Clayton) or later for more rural counties, with most metro Atlanta counties falling in mid-July.

• A successful appeal triggers the 299C freeze, locking your assessed value for three years.

• Georgia is one of the few states where a failed appeal can increase your assessed value, so evidence quality matters.

• Ownwell handles the entire Georgia appeal process on a contingency basis; you pay nothing unless your taxes are reduced.

The 45-Day Deadline, Explained

If you own a home in Georgia, your annual assessment notice comes with a ticking clock. In Ownwell's Georgia Property Tax Homeowner Survey, we found that over 8 in 10 Georgia homeowners have never appealed their property tax assessment, and 51% didn't even know they had the right to do so. That means most Georgia homeowners let the deadline pass every year without realizing what it costs them.

Under Georgia Code O.C.G.A. Section 48-5-311, you have exactly 45 days from the date printed on your Notice of Assessment to file an appeal. The clock starts from the date on the notice itself, not the day it arrives in your mailbox. Georgia law does not allow extensions, so if you miss this window, you forfeit your right to appeal for that entire tax year.

A quick note on how Georgia property tax assessments work: your assessed value equals 40% of the appraised fair market value (FMV).

If your county sets your home's FMV at $400,000, your assessed value is $160,000 per O.C.G.A. Section 48-5-7. You can appeal the assessed value or argue that your property isn't being valued uniformly compared to similar homes, but you cannot appeal the tax rate itself.

County assessors across metro Atlanta mail notices between late May and late June, so deadlines vary by county. For a notice dated June 1, your deadline would be July 16. Here are the confirmed 2026 deadlines for major Georgia counties:

Again, deadlines are 45 days from the postmarked date on the Notice of Assessment. Confirm your county's exact date on their assessor website or on our Georgia property tax trends page.

Lastly, even if you're in a county with a later window, the sooner you start gathering evidence, the stronger your case will be.

How to File Your Georgia Property Tax Appeal Before Time Runs Out

Filing an appeal in Georgia requires a few key decisions, but the process itself is straightforward if you stay ahead of the deadline. Here's what we recommend based on our experience handling over one million appeals nationwide.

Step 1: Gather Your Evidence

Before you file anything, pull together the documentation that supports a lower value for your property. The most effective evidence includes:

• Comparable sales: Recent sales of similar homes in your neighborhood that sold for less than your assessed FMV.

• Property record corrections: Errors in square footage, lot size, bedroom or bathroom count, or condition.

• Condition documentation: Photos of needed repairs, outdated features, or structural issues that affect value.

• Repair estimates: Written quotes from contractors for significant issues.

After processing over a million appeals, we've found that three to five well-chosen comparable sales are consistently the strongest piece of evidence you can bring. County boards respond to concrete data, not general arguments about the market.

Step 2: File Using Form PT-311A

Submit your appeal using Form PT-311A from the Georgia Department of Revenue. You can also submit a written letter to your county Board of Tax Assessors that includes your parcel ID, property address, the value you believe is correct, and your chosen hearing method.

Three filing methods are available:

1. Online: Some counties accept electronic filings through their assessor's website.

2. By mail: Send via certified mail to your county Board of Tax Assessors to create a paper trail.

3. In person: Deliver to the Board of Tax Assessors office directly.

Step 3: Move Forward With Necessary Hearings

When you file, you must select one of three hearing options:

• Board of Equalization (BOE): The most common choice for residential properties. Free to file, and you present your case to a panel of local citizens.

• Hearing Officer: Typically used for higher-value or commercial properties. The officer is a trained appraiser or attorney.

• Non-binding arbitration: Requires you to obtain a certified appraisal at your own expense, which can cost several hundred dollars.

For most homeowners, the Board of Equalization is the right starting point. It costs nothing to file, and the hearing process is designed to be accessible.

What to Know About Payment During Your Appeal

Filing an appeal does not pause your tax bill. You may receive a temporary tax bill while your appeal is pending, and Georgia law (HB 197) requires you to pay that bill in full to avoid penalties.

If your appeal succeeds and your taxes are reduced, the county recalculates your bill and credits the overpayment. You are not penalized for appealing, even if the process takes several months to resolve.

Why the Deadline Matters More Than You Think

Missing your appeal deadline doesn't just mean paying this year's bill as-is. It means losing access to one of Georgia's most powerful property tax tools: the 299C freeze.

The 299C Freeze: Three Years of Locked Savings

When you win an appeal in Georgia, the 299C freeze locks your assessed value at the reduced amount for three consecutive years. The county cannot raise your assessed value during that period, even if the local real estate market keeps climbing. That turns a single successful appeal into three years of compounding savings.

Here's what that looks like with real numbers for a typical Georgia home:

In a rising market, the real savings are even larger. Without the freeze, your assessed value could increase each year, pushing your tax bill higher. With the freeze in place, your assessment stays flat while your neighbors' bills climb.

What Happens If You Miss the Deadline or Lose Your Appeal

Missing the Deadline

If you don't file within the 45-day window, you forfeit your right to appeal for that entire tax year. There are no alternative filing windows, late-appeal exceptions, or hardship extensions in Georgia. You'll need to wait until the next annual assessment cycle to try again.

Missing the deadline means paying a bill you believe is too high for the entire year and forfeiting the chance to trigger a 299C freeze that would lock in savings for three years.

Losing Your Appeal

If the Board of Equalization rules against you, you still have options. You can escalate to the Superior Court within 30 days of the BOE decision.

However, there is a risk unique to Georgia that every homeowner should understand before filing...

Georgia is one of the few states where the Board of Equalization can actually raise your assessed value if it determines your property was undervalued. This is why evidence quality matters so much.

To reduce this risk, review your local market data carefully before filing. Use strong comparable sales from the past year and ensure your property details are accurate.

Ownwell reviews relevant market data before filing any appeal in Georgia and may decline to file if the data suggests the current assessment is already at or below market value. That pre-filing analysis protects you from an outcome that could increase your bill.

Recent Georgia Laws That Affect Your Appeal Decision

Georgia's property tax landscape has shifted significantly over the past two years, and several new laws directly affect whether and when you should appeal.

The HOME Act (Senate Bill 33)

Georgia's HOME Act (Homeownership Opportunity and Market Equalization Act) establishes a mandatory cap on assessment increases tied to inflation, effective in 2027, with no local opt-out allowed. This is a significant protection, but it doesn't take effect until next year.

That timing creates a strategic window right now.

If you appeal successfully in 2026 and trigger the 299C freeze, you lock in a lower baseline before the HOME Act cap kicks in. Once the cap applies in 2027, your assessment increases will be measured from that already-reduced starting point.

Referendum A

This 2024 measure raised the personal property exemption threshold from $7,500 to $20,000. While this primarily affects business personal property, it reflects Georgia's broader push toward tax relief for property owners.

Even with these new protections on the horizon, appealing in 2026 delivers two compounding benefits: you lock in a lower assessed value now through the 299C freeze, then start 2027 from that already-reduced baseline as the HOME Act cap takes effect.
