Most Buckhead listings show last year's property tax figure. That number belongs to the seller. It reflects the exemptions the seller filed for, the base values the seller has built up, and the years of capped growth the seller has collected. None of that passes to the buyer.
Until this year, one part of a Buckhead tax bill moved with the market for everyone, and it happened to be the largest part. A state law signed in May changes that starting in 2027. Once it takes effect, the distance between a long-time owner's bill and a new owner's bill can widen every year the owner stays.
Three layers, and the one that floated
A homestead tax bill in the City of Atlanta's Buckhead neighborhoods is mostly three separate levies, and each one has worked differently.
The City of Atlanta has run its own floating homestead exemption since 2005, which limits increases to 2.6% a year, according to the Center for Civic Innovation. Fulton County's freeze sets a base taxable value and lets that base rise each year by the lesser of CPI or 3%, according to the Fulton County homestead exemption guide. Atlanta Public Schools offered a $50,000 homestead exemption, applied after the first $10,000 of value. Its published tax-relief list also includes age- and income-based exemptions, but no assessed-value freeze or cap.
The school layer also carries the most mills.
| Layer | Rate in the current cycle | How the base value behaved before SB 33 | From tax year 2027 |
|---|---|---|---|
| Atlanta Public Schools | 20.3 mills, presented for final adoption Oct. 5, 2026 | No cap. A fixed $50,000 exemption | Statewide floating exemption applies, with 2026 as the base year |
| City of Atlanta | 9.52-mill net general levy in the FY2027 ordinance | Capped at 2.6% a year | Statewide exemption applies, with 2026 as the base year |
| Fulton County | 8.87 mills, kept on Oct. 7, 2026 | Capped at the lesser of CPI or 3% | County opted in to the statewide exemption in 2025 |
APS finance staff presented the 20.3-mill rate at the board's October 5, 2026 meeting, with a tax-levy resolution on the agenda for final adoption. The city's 9.52 mills comes from Ordinance 26-O-1237, adopted June 15, 2026, which says the final rates may be amended once the final county digest arrives. Rough Draft Atlanta reported that Fulton commissioners voted Oct. 7 to keep 8.87 mills. Using those figures, the school rate is higher than the city and county general rates combined.
The uncapped school layer worked as an equalizer. However long someone had owned a Buckhead home, the largest slice of the bill followed the same market values a new buyer faced.
What changed in May
In early 2025, local governments could opt out of the statewide floating homestead exemption created by HB 581. The Atlanta Board of Education voted to opt out on Feb. 10, 2025, and the City Council also voted to opt out. Fulton County did not. Under the text of HB 581, the statewide exemption limits yearly growth in a homestead's taxable base to the inflation rate.
Governor Kemp signed SB 33 on May 11, 2026. The bill text makes the statewide base-year homestead exemption mandatory for all political subdivisions and repeals the opt-out subsections. The Georgia Municipal Association's guide to SB 33 says that for jurisdictions that had opted out, "the base year established will be 2026 and the first year the homestead exemption will be effective will be 2027." The same guide says the value "is reset to fair market value for taxable purposes upon sale."
APS staff addressed the change at the October 5 meeting. "We know that they closed the door um on House Bill 581. So, we cannot opt out of that anymore," a finance presenter told the board. The presenter added that the change "is going to cost us revenue."
The same presentation explains why the timing matters for owners. Staff said Fulton's overall digest was up about 6.5% for 2026, with the residential digest up 2.9% and the commercial digest up about 9%. The 2026 assessments become the starting point for the new school-layer cap.
Why the gap grows the longer a seller has owned the home
From 2027, a Buckhead homeowner who keeps a home gets inflation-limited growth on the school layer as well as the city and county layers. A buyer gets a new start. HB 581 states that the exemption does not transfer to a later owner. The one exception is a surviving spouse.
Each year the seller stays, any market gain beyond inflation goes into a gap between the seller's capped taxable value and the value a buyer starts from. Before SB 33, that gap could build only on the city and county layers. After 2027, it builds on all three, including the one with the highest rate.
This sets up an incentive that matters most to two of Buckhead's most common sellers: the long-time owner thinking about downsizing and the family moving up within the neighborhood. A move restarts the next home's tax history from the beginning. For many owners that cost was already real. SB 33 adds the school layer to it, and the added cost grows with each year a seller has held the current home.
For buyers the change is simpler. The tax figure on a listing will reflect more years of capped growth than it does today, and less of it will apply to the buyer.
What actually governs a buyer's first bills
The rules that decide a new owner's tax bill sit in a few specific places:
- Base year. SB 33 defines a new applicant's base year as the assessed value from the tax year just before the exemption is first granted, adjusted for substantial property changes. GMA's summary says the value resets to fair market value at sale. The two texts are worded differently, and a buyer's own facts determine which detail matters.
- The year after a sale. Under Georgia's appraisal procedures rule, after an arm's-length sale, the combined land and improvement value for the following year cannot exceed the sale price, adjusted for non-real-estate items. Major renovations and similar changes after the sale can be added on top.
- Filing. The exemptions are not automatic for a new owner. Fulton's guide says owners must reapply whenever the names on the deed change. Fulton's March 2026 notice gave April 1 as the deadline for a 2026 exemption. SB 566 extends the application window through the assessment-appeal period for tax years starting on or after Jan. 1, 2026.
- Who qualifies for which year. Fulton County said owners eligible for 2026 who missed April 1 could apply during the appeal period. People who did not own their home on Jan. 1 can apply for 2027.
- The notice calendar. Fulton made 2026 assessment notices available on June 19, 2026. Owners had a 45-day appeal window, and the county gave July 31 as the deadline for most notices, subject to the date printed on each individual notice. Under SB 566, the notices now show estimated tax savings from exemptions instead of an estimated rollback rate.
These are summaries of public rules, offered as general information and not as legal or tax advice. A tax professional or the Fulton County Board of Assessors can confirm how they apply to a particular property.
How this shows up at the negotiating table
On a long-held Buckhead home, the tax line in the listing is now a figure a buyer's side will likely discount. A careful buyer will estimate a bill from the purchase price and current millage rather than from the seller's history. A seller who expects that question can answer it plainly with real numbers.
For move-up families and downsizers, the same rules affect the decision to sell at all. The carrying cost of the next home has to be estimated from its purchase price and today's rates, not from what the current home costs to hold. That estimate is worth doing early, because the school layer has the most mills and is the one where long-time owners will see the most new protection from 2027.
A few direct questions
Does the City of Atlanta's 2.6% cap continue alongside the statewide exemption? SB 33 makes the statewide exemption apply to the city but does not settle this question. The Fulton Board of Assessors is the place to confirm how the two interact for a given parcel.
Does SB 33 change the Fulton County layer? Fulton commissioners voted to opt in to HB 581 in January 2025, so the county layer was already covered. The new effect in Buckhead falls on the city and APS layers.
Did APS lower its rate this year? At the October 5 meeting, staff described 20.3 mills as below a 20.61-mill rollback rate and estimated about $10 million in savings for taxpayers.
