Georgia's 3-Year Property Tax Freeze After You Win an Appeal

Most homeowners think of a property tax appeal as a single-year transaction: you challenge this year's value, you win or you don't, and next year you start over. Georgia law quietly says otherwise. There's a provision — practitioners call it the "299(c) freeze" — that rewards a successful appeal with a multi-year lock on your assessed value.

It's one of the most valuable and least-understood features of the Georgia property tax system, and it changes the math on whether an appeal is worth the effort.

What the 299(c) freeze actually is

The freeze lives in OCGA § 48-5-299(c). In plain language: when you appeal your assessment and win a reduction, the county generally cannot increase your assessed value for the year you appealed and the next two years after that. Add it up and you get a window of roughly three years during which your assessed value is held in place.

The logic is fairness. If a homeowner goes to the trouble of proving their value was too high, it would be galling for the county to simply mark it right back up the following year. The freeze prevents that, giving the win some staying power.

Why this changes the math

Think about what the freeze does to the value of an appeal. Say you successfully knock a meaningful amount off your fair market value. Without the freeze, that's one year of savings. With it, the lower value generally carries for three years — so your savings roughly triple from a single, one-time effort.

That's also why a real over-assessment is so worth challenging in Georgia specifically: the upside isn't a one-off. It's a saving that compounds across the freeze window before the county can revisit the value.

The exceptions: when the freeze can break

The freeze is generous, but it isn't absolute. The most important exception is substantial additions or improvements to the property. If you finish a basement, add square footage, build an addition, or otherwise materially change the property, the county can reassess to reflect that new value — the freeze doesn't shield improvements you genuinely made.

This is reasonable: the freeze protects the value you successfully argued for, not a different, larger house you built afterward. There are other situations that can affect how the freeze applies as well, which is part of why it helps to have someone who knows the process in your corner.

How you actually get the freeze: you have to win first

The freeze only kicks in after a successful appeal — which means everything upstream of it matters. You still have to file on time, build the evidence, and prevail on the value. The freeze is the reward at the end of that process, not a shortcut around it.

That's why the fundamentals are worth getting right:

• File within your window. In Fulton County, that's 45 days from your notice — see the 45-day deadline guide.
• Bring evidence that wins. Recent comps or a recent purchase price below your assessment do the heavy lifting. The full playbook is in our Fulton County step-by-step appeal guide.
• Only pursue real over-assessments. A long-shot appeal that loses gets you no freeze at all.

The freeze vs. the HB 581 cap — two different things

Don't confuse the 299(c) appeal freeze with the newer statewide HB 581 floating homestead cap. They both limit increases, but they're separate mechanisms:

• The 299(c) freeze is earned by winning an appeal and holds your assessed value for about three years.
• The HB 581 cap is an exemption that limits annual growth in a homestead's taxable value to inflation — no appeal required, but it only applies where it's in effect and to homesteaded property.

In practice, they can stack in your favor. We break down the homestead side in our Georgia homestead exemption and HB 581 guide.

The honest bottom line

The 299(c) freeze is one of the best reasons to take a Georgia appeal seriously — but only when you actually have a case. Winning is what unlocks it, and winning takes a real over-assessment plus solid evidence. If your number is fair, there's no freeze to chase and we'll tell you so. If it's genuinely too high, the freeze means the payoff is bigger than most people realize.
