Georgia’s HB 581 rewrote the 299c property tax freeze rules in 2025. Under the old law, attending your BOE hearing locked your value for three years. Now only actual reductions qualify, making strong comparable sales evidence essential for your appeal.
If you've ever filed a property tax appeal in Georgia, you probably know about the 299c freeze — the three-year value lock that kicked in after your Board of Equalization hearing. It was one of the best-kept advantages in Georgia property tax law. But the georgia 299c freeze law change 2025, enacted through HB 581, fundamentally rewrites who qualifies. Under the old rules, roughly 90–95% of residential freeze grants went to homeowners whose values stayed the same — not reduced. That entire category is now eliminated. If your appeal doesn't win a reduction, you don't get the freeze. Period.
This isn't a minor tweak. It changes the math on whether to appeal, how to prepare, and what's at stake if you show up unprepared.
The 299c property tax freeze locks your assessed value for three years after a Board of Equalization hearing — the appeal year plus the next two. During that window, your county can't raise your assessed value, even if the market climbs 10% a year. For a deeper explanation of how the freeze works, start with our full 299c guide.
What changed in 2025 is a single word — but it's the word that matters most.
The old statute granted the freeze when your property value was "reduced or is unchanged" after a BOE hearing. The new statute only grants it when the value is "reduced."
Here's the exact language shift:
That removed phrase — "or is unchanged" — was doing enormous work. The vast majority of residential appellants who went to a BOE hearing walked out with the same assessed value they started with. Under the old rules, they still got a three-year freeze. Under the new rules, they get nothing.
The change was enacted by 2024 Georgia Laws 379, § 1-5, which amended O.C.G.A. § 48-5-299.
The legislature wasn't targeting homeowners who legitimately believed their assessment was too high. They were targeting a pattern that had turned the appeals system into a tax avoidance strategy for large commercial property owners.
In some counties, the numbers were staggering. In Paulding County, 79% of all property tax appeals were filed by corporations — and 54% came from a single entity. These weren't homeowners concerned about a sudden jump in assessed value. These were sophisticated operations filing appeals with no intention of winning a reduction, knowing the freeze alone was worth significant money on multi-million-dollar commercial properties.
The Georgia Assessors' Association called HB 581 "probably the biggest legislative change since the early 90s." The legislature closed the loophole — but they closed it for everyone, homeowners included.
There's a silver side to this. With fewer strategic "file and freeze" appeals clogging the system, BOE hearings may be scheduled faster, and boards may have more time to consider each case on its merits. If you're filing because your home is genuinely over-assessed, that's good news.
The new rules apply to taxable years beginning on or after January 1, 2025. Here's the timeline:
If you filed an appeal for the 2024 tax year or earlier, the old "reduced or unchanged" rule still applied. Starting with 2025 assessments, you're under the new rules. That means any appeal you file in response to your 2025 or 2026 assessment notice falls squarely under the revised law.
The practical impact depends on your situation, but here's what the numbers look like.
Consider a Gwinnett County homeowner with a home assessed at $400,000 fair market value. The combined millage rate is around 30 mills.
Under the old rules: You filed an appeal. The BOE confirmed your value at $400,000 — unchanged. You still got the three-year freeze. Assuming the market appreciates 5% annually, that freeze prevented reassessment and saved you roughly $854 over three years just by keeping your value locked.
Under the new rules: Same scenario. The BOE confirms $400,000. No reduction means no freeze. Your property gets reassessed each year at market rate. Those savings disappear.
If you win a reduction: Say you present strong comparable evidence and the BOE reduces your value to $375,000. You get the freeze at $375,000. Combined tax reduction plus three years of freeze protection: approximately $2,954 in total savings versus having never appealed.
Here's how the freeze value scales by home value (at 35 mills, 5% annual appreciation):
In a hotter market with 10% appreciation, the freeze on a $400,000 home is worth $1,736 over three years — even before counting the value reduction itself.
The takeaway: under old rules, even an unsuccessful appeal could be worth $641 to $1,736 just from the freeze. Under new rules, an unsuccessful appeal is worth $0. Preparation is no longer optional.
The days of filing a one-page appeal form and hoping for the best are over. You need written evidence supporting your opinion of value — and you need it before you walk into (or dial into) your hearing.
The legal bar is actually low. The statute requires "some written evidence." But in practice, a few carefully selected comparable sales within your neighborhood carry far more weight than a general complaint about rising values.
What works:

Yes. You must attend the hearing — either in person or through an authorized representative — and provide written evidence. Failing to do either one disqualifies you from the freeze.
This is critical because an estimated 17% of appellants don't show up to their BOE hearings. Under the old rules, some of those no-shows still got their values confirmed at the same level and received a freeze by default. That's no longer possible.
County hearing formats vary. Fulton and Gwinnett Counties offer virtual hearings. Some smaller counties require in-person attendance only. Check your hearing notice for details.
If you'd rather not navigate the hearing yourself, AppealAlly's Full-Service Appeal handles everything — filing, evidence preparation, hearing attendance, and deadline monitoring — for 30% of your first-year savings with nothing due upfront.
After you file your PT-311A appeal, the county assessor may issue a PT-306C — a revised assessment notice with a new value. This is the county's counter-offer.
If you receive a PT-306C and accept the new value, your appeal ends there. If you want to continue to the BOE hearing (which you need to reach if you want the freeze), you must respond within 30 days. Miss that deadline and your appeal dies — no hearing, no freeze opportunity.
Yes, and this is one of the most common mistakes. If you're currently in an active three-year freeze period and you file a new appeal, you break the existing freeze. O.C.G.A. § 48-5-299(c)(3) is explicit about this.
Before filing, check whether you're still within a freeze window. If your last successful appeal was in 2024, your freeze covers 2024, 2025, and 2026. Filing again in 2026 would terminate that protection — and under the new rules, you'd only get a new freeze if you win a reduction.
There's also a lesser-known trap: filing a property tax return declaring a different value while your freeze is active can invalidate it. If you're in a freeze, leave things alone until it expires.
The 299c freeze change gets the most attention, but HB 581 included several other provisions worth knowing about.
Sale price as assessment cap removed. Previously, some counties informally capped assessed values at recent sale prices. The new law doesn't mandate this, but the broader reassessment transparency provisions mean your assessment should more closely reflect actual market conditions — for better or worse.
Floating homestead exemption. A new exemption that adjusts with your home's value, designed to soften the impact of rising assessments for owner-occupied homes. However, most metro Atlanta counties (Fulton, Gwinnett, DeKalb, Cobb) have opted out. Check whether your county adopted it through the Georgia Municipal Association's HB 581 overview. For a county-by-county opt-out scorecard, see HB 581: What Changed, Who Opted Out.
Rollback rate transparency. Counties must now publish the millage rate that would generate the same revenue as the prior year — and justify exceeding it. This doesn't directly affect your appeal, but it adds accountability to the overall property tax system.
The 2025 georgia 299c freeze law change raises the bar for property tax appeals in Georgia. Filing isn't risky — there's no penalty for an unsuccessful appeal — but it's no longer a guaranteed win. The freeze was a safety net that rewarded you just for showing up. Now it's a prize you have to earn.
That shifts the calculus toward preparation. Strong comparable evidence, hearing attendance, and awareness of procedural deadlines like the PT-306C response window are all necessary ingredients. If your home is genuinely over-assessed — and with Georgia home values averaging over $330,000, plenty are — a well-prepared appeal can still deliver thousands in savings through the combined effect of a lower assessment and a three-year freeze.
The homeowners who will benefit most from the new system are the ones who treat their appeal like it matters. Because now, it does.
