A georgia property tax appeal is one of the only moments in the year when a homeowner gets to push back on a number the county assigned without asking. That number arrives in the mail in late spring, most people glance at it, feel a small knot of frustration, and file it in a drawer. Forty-five days later the right to challenge it is gone until next year.
Most homeowners assume the assessment is a verdict. It is not. It is an opening position produced by mass appraisal software that has never walked through your house, never seen the foundation crack in the basement, and never noticed that the comparable sale it used was a fully renovated home three streets over. The county is not being dishonest. It is being automated. Automation makes mistakes, and the appeal process exists precisely because the state expects it to.
Nicole France pulls comparable sales for a living, which is the exact skill an appeal requires. This post walks through what your notice actually means, how the 45-day window works, what evidence wins, and the three-year freeze rule that quietly changed in 2025.
What the Notice of Assessment Actually Says
Every Georgia county mails an Annual Notice of Assessment to real property owners, generally between May and July. Cobb tends to be earlier, often late April into May. Your notice will contain several numbers, and only some of them matter.
Find the Fair Market Value. That is the county’s opinion of what your home would sell for. Then find the assessed value, which is 40 percent of fair market value under Georgia law. The millage rate gets applied to that assessed number after your exemptions come off.
Your notice also includes an estimated tax amount. Ignore it emotionally and legally. Georgia does not permit you to appeal the tax amount. You may only appeal the value, the uniformity of the assessment, taxability, or the denial of an exemption. Arguing that your bill is too high is not an argument. Arguing that your home is not worth what the county says it is worth is an argument.
The 45-Day Clock Is Real and It Does Not Move
You have 45 days from the notice date to file. The exact deadline is printed on the notice itself, usually in the upper right corner. Do not count from the day you opened the envelope. Count from the date printed on the page.
Georgia applies this deadline strictly. There is no good-cause extension, no informal grace period, and no sympathetic exception for travel or mail delays. If you file on day 46, your value for that tax year is locked except for correcting clerical errors.
Mailed appeals must be received or postmarked by the United States Postal Service by the deadline. Metered postage does not count. Certified mail is worth the few dollars, because it gives you proof.
One More Reason to Open That Envelope
The appeal window now does double duty. Under House Bill 92, passed in 2025, homeowners who missed the April 1 deadline to file a homestead exemption can still file for the current tax year during the 45-day appeal period.
That means the notice you are tempted to ignore is carrying two separate opportunities. If you bought in the last eighteen months and never filed your exemption, this envelope is your second chance. Details on the exemption side are on the Georgia Department of Revenue homestead page, and county specifics vary.
Check both boxes before the clock runs out. One envelope, two chances to lower a bill.
The Evidence That Wins a Georgia Property Tax Appeal
A successful georgia property tax appeal is not built on frustration. It is built on three or four comparable sales that support a lower number, presented cleanly.
Your comparables should have closed within roughly six to twelve months of January 1 of the tax year, sit in your immediate area, and resemble your home in square footage, age, condition, and lot. A 2005 four-bedroom on a half acre is not comparable to a 2022 build on two acres, and the panel will know the difference.
Beyond comps, three other categories of evidence carry real weight:
- Factual errors in the county record. Pull your property card. Wrong square footage, a basement listed as finished when it is not, a bathroom you do not have, or acreage that does not match your plat are all straightforward wins.
- Condition issues. Photographs of a failing roof, dated systems, foundation movement, or deferred maintenance the assessor never saw. Repair estimates from licensed contractors carry more weight than photos alone.
- Your own recent purchase. If you bought the home in an arm’s length transaction near the assessment date for less than the county’s value, that is powerful, though not automatically decisive.
If you are not sure whether you have a case, start by getting an honest read on what your home would actually sell for today. A current home value estimate is a reasonable first checkpoint before you invest hours in an appeal.
Choosing Who Decides Your Case
Georgia’s appeal form, PT-311A, requires you to select who hears your case. Three options exist for residential owners.
Board of Equalization. Three local citizens appointed by the grand jury, trained in valuation and tax law. There is no filing fee. Hearings are informal enough that homeowners represent themselves routinely. This is the right choice for almost every residential appeal.
Hearing officer. A single certified appraiser or attorney, available for higher-value properties. More technical, sometimes more efficient for complex or high-end homes.
Arbitration. Requires you to submit a certified appraisal at your own expense, which typically runs several hundred dollars. Occasionally worth it. Usually not for a standard residential appeal.
If you do not select an option, your appeal defaults to the Board of Equalization. That default is usually the correct answer anyway.
The Three-Year Freeze, and Why the Rules Changed
Here is the part almost nobody knows. Under O.C.G.A. 48-5-299(c), winning an appeal freezes your assessed value for the appeal year plus the two following years. The county cannot raise it during that window even if the market climbs.
That turns a single win into three years of savings. A $1,500 reduction becomes $4,500 without filing again.
The rules tightened starting in 2025 under HB 581 and HB 92. Three conditions now matter. You must actually receive a value reduction, not a no-change ruling. The appeal generally must be resolved beyond the assessor level, meaning at the Board of Equalization, a hearing officer, arbitration, or Superior Court. And someone must appear at the hearing, whether that is you, a family member, or a representative you designate in writing.
Accepting an early reduction offer from the Board of Assessors closes the case but may forfeit the freeze. Skipping the hearing forfeits it too. If the freeze matters to you, see the appeal through and show up.
Where to File in Each Northwest Atlanta County
Appeals go to your county Board of Tax Assessors, not the Tax Commissioner. Those are different offices, and misrouted paperwork is a common way to burn days off a 45-day clock.
Cobb County. File with the Cobb County Board of Tax Assessors. Covers Acworth and Kennesaw addresses inside Cobb.
Cherokee County. File with the Cherokee County Board of Tax Assessors, 2782 Marietta Highway, Suite 200, Canton, or call (678) 493-6120. Covers Woodstock addresses in Cherokee.
Paulding County. File with the Paulding County Board of Assessors, 240 Constitution Boulevard, 3rd Floor, Dallas, or call (770) 443-7606. County information is available on the Paulding County website.
Bartow County. File with the Bartow County Board of Assessors in Cartersville.
One reminder that costs Northwest Atlanta homeowners real time every year. An Acworth 30101 mailing address does not guarantee a Cobb County parcel. Plenty of homes in that corridor sit in Paulding. Confirm your county on the tax record before you mail anything. If you are still learning how the county lines fall across this region, the areas Nicole serves page maps it out.
What Happens After You File
The Board of Tax Assessors reviews your appeal first. They may offer a revised value. If you accept it, the case closes, though remember the freeze consideration above.
If they leave the value unchanged or you decline their offer, the case gets certified to whichever trier of fact you selected. Board of Equalization hearings are typically scheduled within a few weeks to a few months. You will present your evidence, the county will present theirs, and the panel will decide, usually issuing a written decision shortly after.
If you disagree with that decision, you may appeal to Superior Court within 30 days. Before that case proceeds, the county must offer a settlement conference. Superior Court appeals carry filing costs and often involve an attorney, which is a genuinely different level of commitment.
Mistakes That Sink Otherwise Good Appeals
The most common mistake is arguing the wrong thing. Rising millage rates, a neighbor’s lower bill, and general dissatisfaction are not valuation evidence. Comparable sales are.
The second is filing with no case. Under the current rules, a speculative appeal filed just to trigger the freeze no longer works, and a no-change ruling costs you time for nothing. If your value looks fair, the honest move is to skip it.
The third is not showing up. Homeowners assemble strong packets, mail them in, skip the hearing, and lose both the case and the freeze. The hearing is short and informal. Attend it.
What Homeowners Need to Know
The strategy compresses to five steps. Open the notice the day it arrives and write the deadline on your calendar. Compare the county’s fair market value against what your home would realistically sell for today. Pull three or four genuinely comparable sales and photograph anything the assessor could not have seen. File Form PT-311A with your county Board of Tax Assessors, selecting the Board of Equalization. Then show up.
Understand what this process is and is not. An appeal challenges the county’s opinion of value. It does not touch your millage rate, and it is separate from your homestead exemption, though the same 45-day window now lets you handle both. Owners in Northwest Atlanta who bought during the 2021 and 2022 run-up are the most likely to have assessments that drifted above current market reality, particularly with inventory up sharply and price reductions common across Acworth, Dallas, and Woodstock.
Property tax law changes frequently, county procedures differ, and your situation may involve factors this post does not cover. Confirm every deadline directly with your county Board of Tax Assessors, and consult an attorney or CPA for guidance specific to your circumstances.

Frequently Asked Questions
Does filing an appeal make the county reassess my home more aggressively later?
No. Georgia counties reassess annually as a matter of routine, and filing an appeal does not flag your property for punitive treatment. If you win, the three-year freeze actually protects you from increases during that window, which is the opposite of the fear.
Can I appeal if I just bought the house this year?
Yes, and recent buyers often have the strongest evidence. An arm’s length purchase price near the assessment date is meaningful evidence of market value. Be aware that a purchase below the county’s value does not automatically win, since the county may argue the sale was not representative, but it is a solid foundation for a case.
Do I need to hire someone to appeal?
Not for a standard residential appeal at the Board of Equalization. The process was designed for homeowners to navigate themselves, there is no filing fee, and the hearing is informal. Professional help makes more sense for high-value properties, complex valuation disputes, or an appeal headed to Superior Court.
Not Sure Whether You Have a Case
The hardest part of an appeal is the first question: is the county’s number actually wrong? That is a comparable sales question, and comparable sales are what Nicole France works with every single day across these four counties.
If your notice arrived and the number does not feel right, a short conversation and a look at recent sales in your neighborhood will tell you whether an appeal is worth your time or whether the county got it close enough. Both answers are useful. Learn more about Nicole or reach out directly.
