Worried your Georgia property tax could rise if you appeal? It cannot. The Board of Equalization can only lower your value or leave it unchanged. But HB 581 ended the 299c freeze for losing appeals, making strong evidence critical. Here is the real math.
# Can Your Property Tax Assessment Go Up If You Appeal in Georgia?
Every year, thousands of Georgia homeowners stare at an overinflated assessment notice and think the same thing: what if my property tax goes up if I appeal? It is the single most common question — and the single biggest reason people pay more than they should without a fight. The fear is understandable. Nobody wants to poke the bear and end up worse off.
Here is the direct answer: no, your property tax assessment cannot be raised as a direct result of filing an appeal in the same tax year. The Board of Equalization either lowers your value or leaves it unchanged. That is it. But the full picture has gotten more complicated since 2025, when HB 581 changed the safety net that used to protect even unsuccessful appellants. This article breaks down exactly what can and cannot happen — and why the math still overwhelmingly favors appealing.
No. The Board of Equalization (BOE) is limited to two outcomes: reduce your assessed value or keep it the same. Under O.C.G.A. § 48-5-311, the burden of proof at a BOE hearing is on the county Board of Tax Assessors. They have to justify the value they assigned. If you appeal and the panel is not persuaded by your evidence, the worst that happens is you walk out with the same number you walked in with.
There is no mechanism for the BOE to increase your value above what the county already assessed. Your tax bill does not go up. Your assessed value does not go up. You simply stay where you were.
This is worth repeating because online forums and neighborhood chatter regularly get it wrong: filing a property tax appeal in Georgia carries zero risk of an increase at the BOE level.
If you appeal and lose at the Board of Equalization, your assessed value stays at the amount the county originally set on your Annual Assessment Notice. You pay the same tax bill you would have paid if you had never appealed at all.
During the appeal process, your temporary tax bill is calculated at the lesser of 85% of the current year’s assessment or 100% of the prior year’s — whichever is lower. Once the appeal is resolved, any difference is reconciled. You will not face penalties or interest for the appeal period.
You can also withdraw your appeal at any time before the hearing. There is no penalty for filing and later deciding not to proceed.
The one scenario where your value could theoretically increase involves Superior Court. If you lose at the BOE and choose to escalate to Superior Court, the judge is not bound by either party’s proposed value. In rare cases, a judge could set a value higher than the county’s original assessment. But this is a voluntary escalation that you choose — it does not happen automatically, and the vast majority of appeals never reach this stage.
This is where the story gets important. Georgia has long had one of the most homeowner-friendly appeal protections in the country: the 299c value freeze. Under O.C.G.A. § 48-5-299(c), when a homeowner’s assessed value is reduced through an appeal, that value is frozen for three years — the appeal year plus two additional years. The county cannot raise your value during the freeze period unless specific exceptions apply (major renovations, a property sale, or you filing a new appeal).
Before 2025, the old version of the statute read: “When the value of real property is reduced or is unchanged...” That meant even if you appealed and lost — as long as you showed up and presented evidence — you still triggered the three-year freeze at your existing value. It was a powerful insurance policy. Filing an appeal was essentially risk-free because the worst outcome still locked in your current value for three years.
HB 581 changed that. Signed by Governor Kemp in April 2024 and approved by Georgia voters in a November 2024 referendum with 63% support, the bill took effect January 1, 2025. The revised statute removed “or is unchanged” and now reads: “When the value of real property is reduced from the value...” You must win an actual reduction to trigger the freeze.

The core appeal mechanics did not change. Your value still cannot go up at the BOE. But the safety net underneath you is different now. Here is a side-by-side comparison:
Under the old rules, appealing was a pure freeroll. You either won a reduction and got the freeze, or you lost and still got the freeze. Under the new rules, a losing appeal means you go back to the normal reassessment cycle — the county can raise your value the following year without any freeze protection.
This does not mean appealing became risky. It means appealing became something you want to win rather than something you could afford to lose. The quality of your evidence now matters more than it ever did.
Let’s make this concrete. Sarah owns a home in Fulton County.
Sarah has three choices:
Option 1 — Do nothing. She pays $4,800 this year and every year until the county reassesses. No freeze protection. No reduction.
Option 2 — Appeal and win. The BOE agrees her home is worth $350,000. Her tax bill drops back to $4,200. Under the 299c freeze, that value is locked for three years. Total savings: at least $1,800 over three years.
Option 3 — Appeal and lose. The BOE keeps her value at $400,000. She pays $4,800 — exactly the same as if she had done nothing. Under the old rules, she would have gotten the freeze anyway. Under HB 581, she does not. The county can raise her value again next year.
The critical insight: the downside of appealing and losing is identical to the downside of doing nothing. Sarah’s worst case after an appeal is the same as her guaranteed outcome if she never files. The only difference is that under HB 581, she no longer gets a consolation prize for losing. But the prize for winning — $1,800+ in savings over three years — has not changed at all.
No. This is one of the most persistent myths in Georgia property tax, and it has no basis in reality. County assessors do not maintain retaliation lists. They do not flag properties for future increases because the owner filed an appeal.
Georgia counties reassess properties using mass appraisal models — computer-driven systems that evaluate thousands of properties simultaneously based on market data, comparable sales, and property characteristics. Your individual appeal does not change how the algorithm treats your property in future years.
Consider the scale: Fulton County alone processes tens of thousands of assessment notices every year, and only about 4.4% of metro Atlanta parcels file appeals. The assessor’s office is not tracking individual filers for retaliation — they are trying to process a massive volume of valuations within tight statutory deadlines.
The data actually suggests the opposite of retaliation. Among 748,421 Georgia appeals analyzed between 2015 and 2020, 43.5% were settled or withdrawn before a hearing — often because the county agreed to a reduction during the informal review stage. Counties are more likely to negotiate with you than to punish you.
Absolutely. The expected value of filing an appeal is still overwhelmingly positive.
Here is what the numbers look like at a 30-mill combined rate:
The average Georgia homeowner who wins an appeal saves approximately $1,100 per year. With a three-year freeze, that is over $3,000 in cumulative savings — for filing a free form and presenting evidence at a 15-20 minute hearing.
What HB 581 changed is the cost of losing, and that cost is simply the absence of a bonus you would not have earned by doing nothing. Your floor is the same. Your ceiling has not moved. The only thing that shifted is the importance of filing a strong appeal with solid comparable sales evidence.
Since the 299c freeze now requires an actual reduction, the quality of your evidence package is everything. A well-prepared appeal with strong comparable sales is the difference between a reduction and a rubber stamp.
The most effective appeals include three to five comparable sales within a half-mile of your property, sold within the last 12 months, with similar square footage, lot size, and condition. Adjustments for differences between the comparables and your home — documented with clear math — make your case dramatically more persuasive to a BOE panel.

For homeowners who do not want to handle any part of the process, the Full-Service Appeal covers everything from filing to hearing representation for 30% of first-year savings with nothing due upfront.
Georgia gives you 45 days from your notice date to file using the PT-311A appeal form. Counties typically mail notices between April and June, so the window is short.
Your property tax assessment cannot go up as a result of filing an appeal in Georgia. The Board of Equalization either reduces your value or leaves it unchanged. That has not changed.
What did change under HB 581 is the safety net: losing an appeal no longer triggers the three-year 299c freeze. You need an actual reduction to lock in your value. This makes the strength of your evidence more important than ever — but it does not change the fundamental math. The worst outcome of appealing is the same as the outcome of doing nothing.
With 41% of Fulton County homes and 49% of Gwinnett County homes overvalued in 2025, the odds are meaningful that your assessment is higher than it should be. A well-prepared appeal remains the single most effective way to lower your property tax bill — and the best defense against an increase is a well-prepared appeal backed by strong comparable sales data.
