Only 0.4% of Georgia property tax appeals use arbitration — but for the right situation, it's the best path available.
# Nonbinding Arbitration for Property Tax Appeals in Georgia: When It's Worth It and When It's Not
Out of every thousand property tax appeals filed in Georgia, roughly four choose arbitration. That's 0.4% of all appeals statewide, according to Georgia Department of Revenue data from 2015 to 2020. The other 99.6% go through the Board of Equalization or a hearing officer.
So why does nonbinding arbitration property tax Georgia law even exist? And why would you, a homeowner staring at an inflated assessment notice, consider a path that costs money when the alternatives are free?
Because for certain homeowners in certain situations, arbitration is the smartest move available. It puts a licensed appraiser in the decision-making seat instead of a panel of volunteers. It creates a 45-day window where the county can simply accept your value and close the case. And it gives you a fallback to Superior Court if things don't go your way.
The problem is that nobody explains this option clearly. The PT-311A appeal form gives you a single checkbox and a sentence of description. County websites contradict each other. Some still reference binding arbitration rules that haven't applied to residential appeals since 2015.
This article is the deep dive that form doesn't give you. If you're looking for a broader comparison of all three appeal paths, we've covered that in our guide to BOE vs. arbitration vs. hearing officers. What follows here is everything you need to know about arbitration specifically: the process, the costs, the timeline, and a clear framework for deciding whether it's right for your situation.
Nonbinding arbitration is one of three appeal paths available to Georgia property owners who disagree with their assessed property value. When you file your appeal on the PT-311A form, you choose one path: the Board of Equalization, a hearing officer, or arbitration. That choice is irrevocable, so understanding what you're selecting matters.
In arbitration, a state-certified real property appraiser reviews the evidence from both sides and determines fair market value. That's a meaningful distinction from the Board of Equalization, where three citizens from your county (who may or may not have any real estate background) hear your case and vote.
The "nonbinding" part means the arbitrator's decision isn't the final word. Either you or the county can appeal the result to Superior Court within 30 days. This is different from binding arbitration, where both sides are stuck with the outcome (more on that distinction below).
One important limitation: arbitration can only address value disputes. If you believe your property is incorrectly classified, should be exempt from taxation, or is being assessed non-uniformly compared to similar properties, arbitration can't help. The Board of Equalization handles all four grounds (value, uniformity, taxability, and exemption denial). Hearing officers can hear value and uniformity. Arbitration is the most restrictive.
The legal authority for all of this sits in O.C.G.A. § 48-5-311(f), which lays out the entire arbitration procedure in detail. You don't need to read the statute yourself, but knowing where the rules come from helps if a county clerk gives you conflicting information.
There's also no property value threshold for arbitration. Hearing officers are only available for non-homestead properties valued above $500,000. Arbitration is open to any property, any value, homestead or not.
The arbitration process has more moving parts than a BOE hearing, but the timeline is well-defined by statute. Each deadline is mandatory, which actually works in your favor because the county can't drag things out indefinitely.
Here's the full sequence from filing to decision:
The most powerful moment in this timeline is step 4. If the board doesn't respond to your appraisal within 45 days, your appraised value automatically becomes the final assessed value. The board doesn't get an extension. Silence equals acceptance.
This 45-day default acceptance rule is a genuine taxpayer protection buried in the statute, and it's one of the strongest reasons to consider arbitration if you have a solid appraisal. County tax offices are busy. Deadlines slip. If yours does, you win by default.
There's a safety valve built in, too. If you elect arbitration but can't get a certified appraisal completed within the 45-day window, you can redirect your appeal to the Board of Equalization during that same period. You're not trapped.
Either party can request the other side's evidence list at least 10 days before the hearing. This isn't a courtroom, but it's more structured than a BOE hearing. You (or your representative) present your evidence. The county presents theirs. The arbitrator evaluates both and issues a determination.
An important note on burden of proof: when the board of assessors has changed your property's value from the prior year, the burden falls on the board to prove its new value by a preponderance of the evidence. You don't have to prove they're wrong. They have to prove they're right.
This is where Georgia property tax appeals get confusing, and where county websites often get it wrong.
From 2010 to 2015, Georgia only offered binding arbitration for property tax disputes, thanks to SB 346. In binding arbitration, the arbitrator uses what's sometimes called "baseball arbitration": the arbitrator must choose one side's value or the other. No splitting the difference. No independent calculation. Just pick the county's number or the taxpayer's number, and that's final with no appeal.
HB 202, signed into law on May 6, 2015, restored nonbinding arbitration as an option. Under nonbinding rules, the arbitrator isn't limited to choosing one party's value. They can determine any fair market value they believe the evidence supports. And crucially, either side can appeal the decision to Superior Court within 30 days.
Some county websites (Jackson County, for example) still describe their arbitration option using binding-arbitration language. Dade County's site lists both binding and nonbinding as separate options. If you see conflicting information on your county's website, the statute controls. For residential appeals filed today, the process is nonbinding as described in O.C.G.A. § 48-5-311(f).
Why does this matter to you? Because nonbinding arbitration removes the biggest risk of the old system. Under binding rules, if the arbitrator picked the county's value, you were stuck with it. Under nonbinding rules, you still have Superior Court as a backstop. That said, pursuing a Superior Court appeal adds significant legal costs, so "nonbinding" doesn't mean "risk-free." It means "not final."
This is the question that separates arbitration from every other appeal path. BOE hearings cost nothing. Hearing officers cost nothing. Arbitration costs real money, and the total depends on whether you win or lose.
The filing fee varies by county. Most charge the standard $25. DeKalb County charges $217, which is high enough to make you think twice.
If you and the county agree on a single arbitrator and you win (meaning your value is closer to the arbitrator's decision than the county's value), the county pays the arbitrator's fee. If the county's value is closer, you pay.
For a three-arbitrator panel, each side pays for its own arbitrator, and they split the cost of the third.
Arbitrator fees aren't standardized, but expect $500 to $2,000+ depending on property complexity and whether it's a single arbitrator or panel.
Arbitration works best when you have strong evidence and want a qualified decision-maker evaluating it.
For homeowners who want professional-grade evidence without the full arbitration cost, AppealAlly's Do-It-Yourself Appeal Kit provides a comparable sales analysis and evidence packet for $79 with a money-back guarantee. That evidence works in any appeal path, including BOE hearings where there's no filing cost at all.
Yes. A certified appraisal is mandatory for arbitration, and there's no workaround.
The appraisal must be performed by a Georgia-licensed appraiser (certified general or certified residential, depending on property type). It must have an effective date no more than nine months before January 1 of the tax year in question. So for a 2026 appeal, the effective date needs to be April 1, 2025, or later.
"Certified" here doesn't refer to a special type of appraisal. It means the appraiser holds a current Georgia certification from the Georgia Real Estate Appraisers Board. A Zillow estimate won't cut it. A comparative market analysis from a real estate agent won't cut it. You need a full appraisal report from a licensed professional.
The cost runs $350 to $750 for a typical residential property. More complex properties, larger acreage, or unique construction can push it higher.
Timing matters. You have 45 days from the board's acknowledgment of your appeal to deliver the completed appraisal. Finding an appraiser, scheduling the inspection, and getting the report back takes time. If you're going to choose arbitration, start looking for an appraiser before you file.
One scenario where this requirement becomes an advantage rather than a burden: you already have a recent appraisal. Maybe you got one for a refinance, a home equity loan, or a pre-listing assessment. If it meets the date requirement and was done by a Georgia-licensed appraiser, you've already cleared the biggest cost barrier. That changes the math completely.
Not every appeal should go to arbitration. Most shouldn't. But certain situations make it the clearly better path.
For detailed evidence-building regardless of which path you choose, our guide on what evidence you need for a property tax appeal covers comparable sales, condition documentation, and presentation strategies.
To put numbers behind the theory, consider a scenario based on typical Gwinnett County appeals.
A homeowner has a 4-bedroom, 2,800-square-foot home built in 2005. The county's 2026 assessment comes in at $525,000, a $75,000 jump from the prior year. The homeowner had the property appraised six months earlier for a potential listing at $460,000. Three comparable sales within half a mile ranged from $440,000 to $475,000. The home also had about $25,000 in deferred maintenance (aging HVAC, dated kitchen) that the county's mass assessment didn't account for.
The homeowner chose arbitration for two reasons: they already had a qualifying appraisal (so no additional cost there), and they'd gone through the BOE the previous year feeling their appraisal evidence was brushed aside.
What actually happened? The county settled before the hearing even took place. This isn't unusual. According to Georgia DOR data, 43.5% of appeals are settled or withdrawn before a hearing. When the board saw a professional appraisal at $460,000 supported by recent comparables, they agreed to $470,000.
The math:
Without the existing appraisal, the cost calculation changes. Add $500 for a new appraisal and the net drops to $1,455, still substantial. But if the expected reduction had been $20,000 instead of $55,000, the annual savings of $240 barely covers the appraisal cost over three years.
That's the core arithmetic of the arbitration decision. The reduction has to be large enough to absorb the costs.
Because the arbitration is nonbinding, the story doesn't necessarily end with the arbitrator's determination. Either you or the county can appeal to Superior Court within 30 days.
For context, only about 3.5% of Georgia property tax appeals reach Superior Court (with an average property value of $3.1 million in those cases), per Georgia DOR data. Superior Court appeals involve attorneys, court costs, and a longer timeline, so they're typically reserved for high-value commercial properties or cases with significant dollars at stake.
For most residential homeowners, the arbitrator's decision is effectively final. You can appeal to Superior Court, but the cost of doing so (easily $5,000 to $15,000 in legal fees) usually outweighs the potential benefit on a residential property.
If the arbitration results in a lower value than the county's original assessment, that reduction triggers Georgia's 299c value freeze. Under current law (as amended by HB 581 effective January 1, 2025), a successful appeal freezes your assessed value for two additional years. That means one year of effort generates three years of savings.
On the fee recovery side, if your value was closer to the arbitrator's decision (in a single-arbitrator scenario), the county pays the arbitrator. But your appraisal cost is never recovered. Factor that into your break-even calculation: you need enough savings over three years to cover the appraisal cost plus any risk of paying the arbitrator if you lose.
Nonbinding arbitration occupies a narrow but powerful lane in Georgia's property tax appeal system. It puts a certified appraiser (not a volunteer panel) in charge of evaluating your evidence. It creates a 45-day window where county inaction becomes automatic acceptance of your value. And it preserves your right to appeal to Superior Court if the decision goes against you.
The tradeoff is cost. You'll spend $375 to $967 minimum, and potentially more if you lose. That makes arbitration a poor fit for small disagreements but a strong fit when you already have a qualifying appraisal, when the gap between your value and the county's is substantial, and when you want your evidence evaluated by someone who understands real estate valuation professionally.
If you're filing a PT-311A form this year, take the time to run the break-even numbers before checking that arbitration box. For the right situation, it's the best path Georgia offers. For the wrong one, the free BOE hearing gets you 90% of the way there.
