What Are Coweta County, GA Property Taxes in 2025?
Coweta County has the lowest school tax rate in metro Atlanta — 15 mills for 2025, the lowest the county has set since 1982. On a $500,000 home before exemptions, you’ll pay roughly $4,725 a year in unincorporated Coweta or Sharpsburg, $5,342 in Newnan, or $5,643 in Senoia. That school rate alone runs about $920 less per year than Fayette County on the same home.

Most buyers researching the South Atlanta suburbs land on Fayette County first and never look any further west. That’s a mistake — at least once you start running real numbers. Coweta County has quietly built one of the most competitive property tax pictures in the entire metro Atlanta area, and the buyers who find that out usually do it after they’ve already picked a different county.
So here’s the full breakdown for 2025: how Georgia property taxes actually work, what you’ll pay city by city, and the exemptions that can take real money off your annual bill.
How Georgia Property Taxes Work (the Quick Version)
Before the city numbers make sense, you need three concepts.
Georgia taxes 40% of market value, not 100%.
That 40% number is your assessed value. On a $500,000 home, you’re only being taxed on $200,000. Every rate you see in this post gets applied to that figure, not the full price.
Rates are expressed in mills.
One mill equals $1 of taxes for every $1,000 of assessed value. So on a $200,000 assessed value, one mill works out to $200 a year. Once you have that in your back pocket, comparing cities gets a lot easier.
Your bill is layered.
The county sets one rate. The school board sets another. If you buy inside city limits, the city stacks a third rate on top of those. None of them coordinate — they each set their number, and you pay all of them. Which is why two houses a few miles apart can have very different bills, even in the same county.
You’ll also see the phrase maintenance and operations millage on your bill. That’s just the official term for the part of the rate funding day-to-day government — courts, roads, administration. Think of it as the operating budget expressed as a tax rate.
House Bill 581 — the Save the Homes Act
Georgia passed HB 581 in 2024, and it took effect January 1, 2025. The short version: once you have a homestead exemption on your primary residence, your taxable assessed value can only grow at the rate of inflation, not at whatever the market is doing.
That matters in a market like ours. If home values in your neighborhood jump 10–15%, your tax bill is shielded — your 2024 value becomes the base, and it adjusts slowly from there.
One catch worth knowing: the exemption doesn’t follow you. When you close on a new home, you have to reapply. In Coweta, the deadline is April 1. Miss it and you wait another year.
And if you ever look at your assessment notice and think the county overvalued your home, you can challenge it. Watch Daphne explain the appeal process at 4:05 — but be careful. When the county takes a second look, they’re not required to come back lower. They can come back higher. Go in with actual comparable sales data, not a feeling.
Why Coweta’s School Rate Changes the Whole Picture
Here’s the part that surprises people. Coweta County has the lowest school tax rate in the entire metro Atlanta area as of 2025 — 15 mills.
The Coweta County school board voted to drop the rate to 15 mills for 2025, down from 15.41 the year before. Back in 2019, the rate was 18.59. They’ve cut it by nearly four mills over six years. Fifteen mills is the lowest Coweta school rate since 1982 — and the lowest in metro Atlanta right now.
Compare that to Fayette County’s school rate of 19.6 mills, and you have a 4.6 mill gap. On a $200,000 assessed value, that gap is $920 a year — every year you own the home.
School taxes are typically the largest single line on your annual bill, which is why a 4.6 mill swing isn’t a rounding error. It’s the kind of number that compounds quietly over the time you own a house.
The Confirmed 2025 Coweta County Rates
Coweta restructured the bill in 2025, splitting what used to be one combined county number into separate line items so you can see exactly what you’re paying for. There are six county-side rates now:
- General maintenance and operations: 4.817 mills
- Parks and recreation: 0.397 mills
- 911: 0.321 mills
- Emergency medical services: 0.420 mills
- Fire district: 2.500 mills
- Fire bond: 0.189 mills
That totals 8.626 mills on the county side. Add the 15 mill school rate, and unincorporated Coweta lands at 23.626 mills before any city layer.
If you’re still in the research phase and trying to decide between Fayette, Coweta, and Henry, the numbers in this post are exactly the kind of side-by-side detail my free South Atlanta Relocation Guide goes deeper on — neighborhoods, schools, taxes, commute times, and the things you only learn from working in these communities every week.

What You’ll Pay City by City on a $500K Home
These are pre-exemption numbers based on confirmed 2025 millage rates. Your homestead exemption will lower them once it’s filed.
Sharpsburg / Unincorporated Coweta
Sharpsburg is mostly unincorporated, which is great news for taxes — there’s no city millage layer. You’re paying 8.626 mills county side plus 15 mills school. That’s it.
On a $500,000 home: ~$4,725 a year, about $394 a month.
It’s the cleanest tax in Coweta and hard to beat if you want land and space. Watch Daphne walk through Sharpsburg at 7:42.
City of Newnan
Newnan is the county seat and the largest city in the Coweta market. It’s the one I recommend most often for buyers who want walkability, downtown amenities, and easy I-85 access alongside competitive taxes.
The city set its 2025 millage at 3.082 mills, down from 3.12 the year before. Worth knowing: Newnan has taken the full rollback rate in six of the last seven years. That means the city is consistently leaving money on the table rather than collecting every dollar the formula would allow — and that track record matters when you’re thinking about long-term cost of ownership.
On a $500,000 home: ~$5,342 a year, about $445 a month.
For that, you get the downtown square, the historic neighborhoods, Ashley Park and Newnan Crossing for shopping, and a three-mile drive to I-85.
City of Senoia
Senoia has become one of the most sought-after small towns in the entire South Atlanta market. If you’ve driven down Main Street, you already know why.
One thing to confirm before you fall in love with a Senoia listing: the city has a large geographic footprint, and a lot of what shows up with a “Senoia” address is actually unincorporated. Inside city limits, you pay the city millage. Outside, you don’t. Check before you write the offer.
The city held its rate at 4.587 mills for 2025 — the same as last year, and down from 5.605 in 2018. Senoia has grown a lot in those years without raising rates, which says something about how it’s managing growth.
On a $500,000 home (inside city limits): ~$5,643 a year, about $470 a month.
The city rate is higher than Newnan’s, but Coweta’s 15 mill school rate is doing the heavy lifting on the savings side. The total picture is still attractive.
Coweta vs. Fayette County — The Real Comparison
This is the comparison most relocation buyers are actually trying to make. Here’s how the numbers shake out on a $500,000 home before exemptions.
- Sharpsburg / unincorporated Coweta: ~$4,725/year
- Newnan: ~$5,342/year
- Senoia: ~$5,643/year
Coweta’s county-side rates run about 0.833 mills higher than Fayette’s. But Coweta’s school rate advantage of 4.6 mills more than covers it. Netted out:
- Unincorporated Coweta runs about $750 a year less than unincorporated Fayette at the same price point.
- Newnan comes in about $137 less than unincorporated Fayette, even with the city rate added.
The Coweta school board is winning the comparison for the entire county. If you’ve been researching Fayette as the obvious choice — and weighing the broader cost of living in Fayetteville — Coweta deserves a real look on the same spreadsheet.
Senior Exemptions in Coweta — Some of the Best in the Region
Every primary-residence homeowner who files for homestead exemption gets a base deduction off the assessed value. File by April 1, and you’re covered for that year. You don’t reapply annually as long as you stay in the same home.
From there, it gets better fast.
Age 62: Coweta homeowners can apply for a county maintenance and operations exemption if net income doesn’t exceed $10,000. Before you assume you don’t qualify — Social Security and most retirement income are excluded from that calculation. Run the actual numbers.
School-tax exemptions for seniors got a major upgrade. Voters approved new tiers in November 2025, effective in 2026:
- Age 65–70: Exempt from school taxes on the first $75,000 of assessed value
- Age 71–74: Exempt on the first $100,000 of assessed value
- Age 75+: 100% exemption from Coweta school taxes — no income test, no cap on home value
On a $200,000 assessed value at 15 mills, the 75+ exemption alone is $3,000 a year in school taxes — gone. If that sounds like a strong reason to retire to Coweta, you’re not wrong.
Disabled Veteran Homestead Exemption
Georgia’s disabled veteran exemption is significant: up to $121,812 for 2025, adjusted annually based on a formula set by the U.S. Secretary of Veteran Affairs. It applies to every layer of the bill, including the school rate.
On a $200,000 assessed value, knocking off $121,812 eliminates more than 60% of your taxable base before the rate is even applied. To qualify, you need a VA letter confirming a 100% service-connected disability rating, the home has to be your primary residence, and an unmarried surviving spouse keeps the exemption as long as they continue to live there. Watch Daphne cover the veteran exemption details at 13:53.
How to Apply for Coweta County Exemptions
None of this is automatic. You apply in person at the Coweta County Board of Assessors at 37 Perry Street in Newnan. The deadline is April 1.
What to bring:
- Standard homestead: Georgia driver’s license. If the purchase was recent, your warranty deed or settlement statement.
- Senior exemptions: Proof of age, plus your most recent tax return or two consecutive months of bank statements.
- Veteran exemption: Your VA letter with the effective date of your disability rating.
One more reminder I give every client: the homestead exemption doesn’t move with you. When you close on a new home, you go to the office and apply once. After that, it carries forward automatically as long as you stay in the home. It’s worth the trip.
What This Means If You’re Researching the Move
Coweta County keeps surprising buyers who actually run the numbers. The school rate alone sets it apart from most of the metro Atlanta market. The senior exemption program is among the strongest in the region. And cities like Newnan and Senoia offer a quality of life that’s hard to find at this price point anywhere this close to Atlanta.
If you’ve been sleeping on Coweta because you assumed Fayette was the obvious answer, the math says it deserves another look. The buyers I work with usually start with one county in mind and end up choosing based on a side-by-side they didn’t know they needed.
If you want to run real numbers on a real home you’re considering — including how the exemptions you’d qualify for would change the picture — that’s what my free strategy call is for. And if you’re earlier in the research, the free South Atlanta Relocation Guide walks through Coweta, Fayette, and Henry side by side so you can decide where to focus before you start touring.
Tax rates are set annually and can change. Everything in this post reflects 2025 rates as confirmed by the Coweta County Board of Commissioners. Always verify current numbers directly with the Coweta County Tax Commissioner before making a purchase decision.
