Complete Guide to Georgia Property Tax Appeals in 2026

If you're a Georgia homeowner, there's a good chance your property is over-assessed. County assessors across the state use mass appraisal methods that often overvalue individual properties — and that means you could be paying more in property taxes than you should.

The good news? Georgia gives homeowners a straightforward process to appeal their property tax assessment. Even better, Georgia has one of the most homeowner-friendly appeal laws in the country: the 299(c) rule, which freezes your assessed value for up to 3 years after a successful appeal.

This guide walks you through everything you need to know about appealing your property taxes in Georgia in 2026 — from deadlines and evidence to the appeal process and that powerful 3-year value freeze.

Why You Should Appeal Your Georgia Property Taxes

Property tax is the largest recurring expense for most Georgia homeowners, and assessments have been climbing rapidly in metro Atlanta and other growing areas. Here's why filing an appeal makes sense:

• Mass appraisals miss the details. County assessors value thousands of properties at once. They can't account for your home's specific condition, lot issues, or neighborhood factors.
• It's free to file. There is no filing fee to appeal your property tax assessment in Georgia.
• The 3-year value freeze. Under Georgia's 299(c) rule, a successful appeal freezes your assessed value for up to 3 years — meaning you save not just this year, but potentially the next two as well.
• No risk. Your assessed value cannot be raised as a result of your own appeal. The worst outcome is that nothing changes.

Understanding Georgia Property Tax Assessments

In Georgia, property is assessed at 40% of fair market value. This "assessed value" is what your tax rate (millage rate) is applied to. So if your home's fair market value is set at $400,000, your assessed value is $160,000.

Each county's Board of Tax Assessors is responsible for determining the fair market value of all properties within the county. They send annual assessment notices (also called "Annual Notices of Assessment") typically between April and June, depending on the county.

What Your Assessment Notice Tells You

• Current fair market value — what the county says your property is worth
• Previous year's value — for comparison
• Assessed value — 40% of fair market value
• Exemptions applied — homestead, senior, disability, etc.
• Appeal deadline — 45 days from the notice date

Georgia Property Tax Appeal Deadlines

Timing is critical. In Georgia, you have 45 days from the date on your assessment notice to file an appeal. Since counties send notices at different times, there is no single statewide deadline — but most notices arrive between April and June.

If you miss the 45-day window, you'll have to wait until next year's notice to appeal. There are no extensions.

The Georgia Property Tax Appeal Process: Step by Step

Step 1: Review Your Assessment Notice

When your annual assessment notice arrives, compare the county's fair market value to what you believe your property is actually worth. Check for obvious errors: wrong square footage, incorrect number of bedrooms or bathrooms, or features your home doesn't have.

Step 2: Gather Your Evidence

Strong evidence is the foundation of a successful appeal. The most effective types include:

• Comparable sales ("comps"): Recent sales of similar properties in your area that sold for less than your assessed value
• Property condition issues: Photos and documentation of needed repairs, foundation problems, outdated systems, or other deficiencies
• Independent appraisal: A professional appraisal can carry significant weight, especially at the Board of Equalization level
• Assessment errors: Incorrect property data in county records (wrong lot size, extra bathroom counted, etc.)

Step 3: File Your Appeal

Submit a written appeal to your county's Board of Tax Assessors within the 45-day deadline. Most counties accept appeals by mail, in person, or online. Your appeal should clearly state that you believe the assessed fair market value is too high and briefly explain why.

Step 4: Informal Review with the Assessor

After filing, many counties offer an informal review where you can present your evidence directly to an assessor. This is often where cases are resolved — the assessor may agree to reduce your value without a formal hearing.

Step 5: Board of Equalization Hearing

If the informal review doesn't resolve your case, it moves to the Board of Equalization (BOE) — a panel of local citizens who hear both sides and make a decision. You'll present your evidence, the assessor's office will present theirs, and the board will issue a ruling.

Step 6: Superior Court or Arbitration (If Needed)

If you disagree with the BOE's decision, you can appeal further to either the Superior Court or, for residential properties valued under $750,000, binding arbitration. Most cases are resolved at the BOE level.

The 299(c) Value Freeze: Georgia's Biggest Tax-Saving Secret

Here's what makes Georgia truly special for property tax appeals. Under O.C.G.A. § 48-5-299(c), when you successfully appeal your property tax assessment, the reduced value is essentially frozen for up to 3 years.

This means the county cannot raise your assessed value during that period — unless you make significant physical improvements to the property (like an addition or major renovation). Normal market appreciation? Doesn't matter. Your value stays locked in.

This is an enormous advantage. In states like Texas, you have to appeal every single year to keep your value in check. In Georgia, one successful appeal protects you for three years.

Tips for Winning Your Georgia Property Tax Appeal

1. Use recent, local comps. Sales within the last 6–12 months in your immediate area are the gold standard.
2. Document everything. Take photos of any property issues — deferred maintenance, foundation cracks, outdated kitchens, etc.
3. Know your county. Each county's Board of Equalization operates slightly differently. Familiarity with local procedures helps. See our county-by-county guide.
4. Be professional and concise. At hearings, present your evidence clearly. Stick to facts and comparable data.
5. Consider professional help. An experienced representative knows what evidence works, how to present it, and how to navigate the system efficiently.

Should You Hire a Professional?

You can absolutely file and manage your own appeal. But there are good reasons to consider professional help:

• Time savings: The process involves research, paperwork, and potentially attending hearings during business hours.
• Better results: Professionals have access to comp data, know what works in each county, and present cases regularly.
• No risk: With a contingency-based service like OverAssessed, you pay nothing unless your taxes are actually reduced.
• No license required: In Georgia, a property owner can authorize any representative to file on their behalf with a Letter of Authorization (LOA). OverAssessed handles this seamlessly.

Frequently Asked Questions

Can my taxes go up if I appeal?

No. Georgia law protects homeowners who file appeals. Your assessed value cannot be increased as a result of your own appeal.

How long does the appeal process take?

From filing to resolution, most appeals take 2–4 months. Simple cases resolved at the informal review stage can be much faster.

What if I just bought my house?

If you recently purchased your home, your purchase price is a strong piece of evidence — especially if it's lower than the assessed value. Recent sales carry significant weight in Georgia appeals.

Can I appeal every year?

Yes, but with the 299(c) value freeze, you may not need to. A successful appeal freezes your value for up to 3 years, so you may only need to appeal every few years.
