Every listing in Chatham County shows a property tax figure, usually pulled straight from the seller's most recent bill. Buyers do the sensible thing and use it to budget. Then the first tax bill arrives under their own name, and the number is nowhere close.
This isn't a mistake on the county's part, and it isn't a fluke. It's how Savannah's property tax system is built to work, and a set of recent state law changes just made the gap bigger and harder to predict.
The Number on the Listing Is a Snapshot, Not a Forecast
Chatham County has run a homestead protection called the Stephens-Day exemption since 1999. It freezes a homeowner's taxable value to the year they first qualify, which is why longtime owners in Ardsley Park or the Landmark Historic District can be sitting on tax bills that look almost frozen in time compared to what their homes would sell for today.
That frozen number belongs to the seller. It does not transfer with the deed. When a new owner takes title, the county starts over, and under recent legislation the starting point is no longer guaranteed to be what the buyer paid. The Chatham County Board of Assessors states plainly that under HB 581 and HB 92, the sale price is no longer treated as the ceiling on the following year's assessed value. A home can be appraised above what someone just paid for it, based on market activity and comparable sales, not the closing statement.
What Stephens-Day Actually Freezes, and What It Doesn't
Stephens-Day is genuinely one of the more generous protections in the state, and Savannah's own explanation of it calls it the best homestead exemption in Georgia after more than a quarter century in place. But the freeze has two limits worth knowing before you rely on it:
First, it only applies once you've filed for homestead exemption as the owner-occupant, and you have to occupy the home as your primary residence as of January 1 of the tax year you're claiming it. Second, the freeze isn't perfectly flat. The Board of Assessors notes that the school system's levy and the City of Savannah's bill both carry a Consumer Price Index adjustment that gets added to the base year value annually, even after you've qualified. The county portion holds steady. The school and city portions creep.
Your 2026 Filing Window, at a Glance
The timeline for filing isn't the same every year, because it's tied to when the county mails its Notice of Assessment. Here's how this year has actually run:
| Milestone | 2026 Date |
|---|---|
| Standard annual filing deadline | April 1 |
| 2026 Notices of Assessment mailed | June 16, 2026 |
| Extended exemption and appeal deadline | July 31, 2026 |
| Appeal window on any notice | 45 days from mailing date |
The extension to July 31, 2026 was confirmed by Chatham County after this year's notices went out later than the standard cycle. Tax Commissioner Sonya L. Jackson framed it as a second chance for anyone who missed the April date. The practical lesson for a buyer closing later in the year is that the April 1 deadline you'll read about everywhere is not always the real deadline. The real deadline tracks each year's Notice of Assessment, and it only shows up after the county mails it.
The Law Just Changed Under Buyers' Feet
For years, a common assumption among Savannah buyers was that a fresh purchase price would cap the following year's assessment, since the county typically used the sale as the new benchmark. HB 581 and HB 92 removed that assumption. The Board of Assessors' own FAQ addresses this directly, describing a scenario where someone bought a home for less than the current fair market value shown on their notice and explaining that the sale price is no longer the maximum allowed value for the following tax year.
That matters most for anyone buying below asking or catching a motivated seller. A lower purchase price used to translate fairly directly into a lower first-year tax bill. Now the county can appraise based on broader market trends, which means two buyers who closed on similar homes for different prices could end up with assessed values closer together than their purchase prices were.
Why Savannah Told the State's New Tax Break No Thanks
In 2024, Georgia voters approved HB 581, a statewide floating homestead exemption modeled on Chatham County's own Stephens-Day law. Every local government in the state then had to decide whether to opt in or out. The City of Savannah's city council voted unanimously to opt out in February 2025, and the reasoning was straightforward: the 25-year-old Stephens-Day model already locks in home values and tax rates in a way city leaders felt didn't need replacing.
For a buyer, the takeaway is that there's no extra statewide layer stacking on top of Stephens-Day here. The city's own guidance confirms that in counties with multiple exemptions, taxpayers get whichever provides the greater reduction, and virtually all Chatham County residents will remain under Stephens-Day regardless of how the opt-in vote went elsewhere in the state. Stephens-Day is still the one lever that matters, and filing for it promptly after closing is still the single most consequential thing a new owner does for their tax bill.
The Rate Held Steady. The Bill Still Climbed
It's tempting to assume a stable or falling tax rate means a stable bill. Savannah's own school district shows why that isn't true. In its summer 2026 budget hearings, the Savannah-Chatham County Public School System proposed holding its millage rate flat at 17.331 mills, the same rate the board settled on the year before after reducing it slightly from 17.481 mills. District spokesperson Kurt Hetager was direct about what that means for homeowners: if bills go up anyway, it's because assessed values rose, not because the district raised the rate.
That's precisely the mechanism a new buyer walks into. You close at today's market price, which is higher than what the seller's frozen base year reflects, and your first assessment picks up that gap in full. A flat or even reduced millage rate does nothing to offset it, because the rate and the assessed value are two separate variables, and only one of them resets when you buy.
What to Actually Do After You Close
The filing itself is not complicated, but it has hard edges. You'll need a valid Georgia driver's license or ID showing the property address and a vehicle registration in your name at that address. Applications must generally be completed in person at the Board of Assessors office in the Pete Liakakis Government Building at 222 West Oglethorpe Avenue, though online filing is available up until April 1 each year. There is no extension available for a missed deadline within a given tax year. Miss it, and you wait for the next cycle while paying the unexempted rate.
If your Notice of Assessment shows a fair market value meaningfully above what you actually paid, you have the right to appeal, and the window is tight. The Georgia Department of Revenue confirms the appeal must be postmarked no later than 45 days from the mailing date of the notice, not 45 days from when you happen to open the envelope. The Board of Assessors has also flagged that Georgia lawmakers passed SB 566 during the 2025-2026 legislative session with further changes to property tax law that may affect Chatham County taxpayers, so this is a rulebook worth checking again each year rather than assuming last year's process still applies.
A Few Questions Worth Asking Before You Close
Does the seller's homestead exemption transfer to me? No. Stephens-Day is tied to the person who filed it and the year they qualified. A new owner has to file fresh, and the base year resets to reflect the purchase.
What if my assessed value comes in higher than what I paid? Under HB 581 and HB 92, that's now possible even when you bought at a fair price. Your recourse is the 45-day appeal window from the date your Notice of Assessment was mailed.
How do I know if a home already has a value freeze in place? The county's online Property Records Search shows a Value History tab, and a listed reason of "APPEAL DECISION" indicates an existing 299C freeze. That protection is tied to the current owner and does not carry over at sale.
None of this changes whether a home in Savannah is worth buying. It changes whether your first-year budget is realistic. A tax line copied from a listing tells you what the seller pays. It tells you nothing about what you will.
If you're weighing a purchase or sale anywhere from the historic core to Ardsley Park and want a straight answer on what a specific property's tax picture will actually look like under new ownership, that's a conversation worth having before you write an offer, not after your first bill arrives.
