Let’s dive right in — if you own property in Georgia (or you’re house-hunting), buckle up. Home values are shooting up across parts of the state, and that means for many homeowners, the property tax bill that lands in your mailbox this year could hit a lot harder than last year. Between rapidly rising assessments, shifting millage rates, and local governments scrambling to keep up with growth (or budget shortfalls), there are several counties where taxes are on track to climb faster than you might expect.
Here are nine Georgia counties to watch if you care about what your home will cost you — and what you might start paying soon.
1. DeKalb County
DeKalb County is practically waving a red flag when it comes to rising tax burdens in 2025. The county’s governing authority has approved a tentative millage rate of 12.427 mills — that’s 2.690 mills over the computed “rollback” rate, representing a 27.6 percent increase from what the rollback formula would dictate. Even though the combined rate for all levies has been held flat at 20.81 mills since 2015, the reassessment of property values means many homeowners are still looking at significantly larger tax bills.
For those living in parts of metro Atlanta where housing demand has exploded — and with schools, public services, and infrastructure under pressure — the jump in tax obligations feels like the price tag for growth. If your property was reassessed upward even a little, that 27% swing could hit harder than it looks on paper.
2. Cobb County
Cobb County remains one of Georgia’s fastest-growing suburban hubs, and with growth comes rising home values — and rising taxes. According to the 2025 residential property value report, the market value of single-family homes rose about 3.1 percent compared to 2024. That’s not the kind of jump that knocks you off your feet overnight — but consistent annual increases add up over time, especially when many homeowners already operate on tight margins or fixed incomes.
The ripple effect? Expect next year’s tax digest (and likely your bill) to reflect the new valuations. As properties change hands or get upgraded, it’s a reminder that suburban expansion often comes with a hidden cost.
3. Fulton County
In the heart of metro Atlanta, Fulton County continues to see some of the steepest home-value gains statewide — and that typically translates directly into steeper taxes. A recent report showed residential property values increased by 5.9 percent overall, with even bigger upswing among higher-valued homes. It’s not just luxury mansions driving the spike either; mid-range properties saw solid upward movement, pushing more “average” homeowners into new tax brackets.
The truth is, when demand is high and inventory is tight, tax assessments follow market prices — and that upward pressure tends to stick. For many long-time residents, this can feel like being priced out of your own neighborhood without ever moving.
4. Gwinnett County
Though not always in the headlines, Gwinnett County in recent years has seen rapid population growth and mounting development. As demand pushes property values upward, tax bills are likely to follow. In recent statewide property-tax data, Gwinnett had among the highest effective tax burdens for homeowners. This county is part of the broader metro-Atlanta growth wave — new homes, families moving in, and expanding services. With schools, roads, and infrastructure needing funding, officials often lean on property tax increases to keep pace. If you own in Gwinnett and haven’t looked at your latest assessment closely — now might be a good time.
5. Chatham County
Way out on the coast, things are heating up in Chatham County too. As home to the city of Savannah and its surrounding suburbs, Chatham is seeing rising demand for housing — which tends to push up property valuations. According to the latest county-by-county data, Chatham’s effective property tax rate and median tax bills are among the higher ones in Georgia. For coastal homeowners, rising property taxes can clash with other cost pressures like insurance, maintenance, and flood-related expenses. If you own a home in this region, prepare for what could be a steeper climb than many inland counties are facing.
6. Fayette County
Fayette County is often overlooked in discussions about tax spikes, but it’s a place where property value increases and tax burdens have quietly climbed. According to recent data, many mid-sized Georgia counties like Fayette are seeing rising effective tax rates and increased tax bills, even as statewide attention focuses on the major metros. For long-term homeowners, that can mean incremental increases over successive years — enough to shift what was once a manageable payment into a financial burden. Communities that had affordable charm a few years back may now feel the squeeze as valuations edge upward and local government costs rise.
7. Henry County
Henry County, which sits on the growing periphery of metro Atlanta, is another spot where homeowners should keep a close eye. As development expands outward and more people move in, property values tend to follow — and with that, tax bills often climb too. Tax data show that Henry County’s effective property tax burden is already above the statewide median. For families moving into what once felt like affordable suburbs, this means the dream of lower-cost living might be under threat from rising assessments and incremental tax pressure. New growth brings new amenities — but also new expenses.
8. Coweta County
Few counties outside the big metro centers get much attention, but Coweta County is quietly part of the broader shift. As people look for more space and affordability outside major urban zones, places like Coweta become magnets — which can trigger property value hikes. According to recent property-tax data sets, Coweta shows a relatively high effective rate, suggesting that as home values rise, tax bills are likely to follow. This dynamic often sneaks up on homeowners: the neighborhood feels peaceful, the home feels like your refuge, but the tax bill creeping up in your mailbox tells a different story. If you call Coweta home — or are thinking about buying there — it’s worth budgeting for steeper taxes down the line.
9. Butts County
Last but not least, Butts County stands out among Georgia’s smaller and more rural counties, yet it shows signs of rising tax burden that many might not expect. According to county-by-county effective property tax data, Butts is among the counties where rates — relative to property values — are trending upward. As urban sprawl pushes outward, even rural zones can feel the ripple effect of increased demand, leading to reassessments and higher bills. For homeowners who moved here for peace, space, or affordability, that tax increase can sting: what once felt affordable might suddenly feel like a stretch.
What This Means For Georgia Homeowners
If you own — or are thinking of buying — a home in Georgia, these counties show that the property-tax landscape is shifting quickly. Rising home values, population growth, and local budget pressures are colliding to make increases more common than exceptions. It’s a reminder that homeownership isn’t just about your mortgage and that property taxes can sneak up and add real impact to your bottom line.
