Coweta County, GA Property Tax: Rates, Exemptions, and Appeals

Property tax rates and exemptions in Coweta County, GA are built from three stacked millage rates — the county government, the Coweta County Board of Education, and any city you live in — applied to 40% of your home’s fair market value, with homestead, senior, veteran, and conservation-use exemptions available to reduce what you owe.¹ Each taxing authority sets its own rate every year during the budget process, so the combined rate shifts from one tax year to the next. The current Coweta rates are published on the Tax Commissioner’s site at cowetataxcom.com and in the annual tax digest from the Georgia Department of Revenue.²

How Your Coweta County Tax Bill Is Calculated

A mill equals one dollar of tax for every $1,000 of assessed value.²³⁴ Georgia then taxes only 40% of that value.¹

Here’s the math. Say your home has a fair market value of $350,000. Your assessed value is $350,000 × 0.40 = $140,000. If the combined millage for your jurisdiction totals 21 mills, divide 21 by 1,000 to get 0.021, then multiply: $140,000 × 0.021 = $2,940 before exemptions. Any homestead or other exemption reduces the assessed value before the millage is applied, which lowers the final number.

A homeowner in unincorporated Coweta pays county plus school district millage. Inside a city like Newnan, Senoia, or Sharpsburg, a municipal rate stacks on top. Before any of these rates are finalized, the county must publish them in a local newspaper and hold public hearings.⁵

The Standard Homestead Exemption

The most common way to lower your bill is the standard homestead exemption. You must own and occupy the property as your primary residence as of January 1 of the tax year.⁶ The exemption subtracts a set dollar amount from your assessed value before the millage rate is applied.

File the homestead application with the Tax Assessor’s Office by April 1 for it to apply to the current tax year. Applications submitted after April 1 take effect the following year, and the deadline cannot be extended.⁷ Once approved, the exemption renews automatically unless you move, the ownership changes, or you switch to a different exemption.

Senior School Tax Exemptions

Coweta offers several tiers of school tax relief for older homeowners, and the qualifying age is lower than many residents expect. Because the school district levy is the largest part of most tax bills, these are often the biggest-dollar exemptions available.

At the state level, homeowners aged 62 or older whose combined household income (excluding most Social Security and retirement income) does not exceed $10,000 can claim a $10,000 exemption from school taxes.⁷

Beyond that, Coweta has adopted local senior exemptions with no income limits:

At age 65, a $75,000 exemption from school taxes on your assessed value.
At age 71, a $100,000 exemption from school taxes.
At age 75, a full exemption from school taxes.

These are the 2026 tax year figures.⁷ Apply through the Tax Assessor’s Office by April 1.

Disabled Veteran and Surviving Spouse Exemptions

Honorably discharged Georgia veterans rated 100% disabled by the VA — or rated less than 100% but compensated at the 100% rate due to unemployability — qualify for a homestead exemption from all ad valorem taxes. Veterans who have suffered the loss or permanent loss of use of a hand, foot, or eye also qualify. The exemption amount is indexed annually by the U.S. Secretary of Veterans Affairs under 38 U.S.C. § 2102; for 2025 the maximum was $121,812.⁸ Confirm the 2026 figure with the Coweta County Tax Assessor’s Office when you apply.

The unremarried surviving spouse of a peace officer or firefighter killed in the line of duty receives a complete homestead exemption covering the full value of the home from all ad valorem taxes. It lasts as long as the spouse remains unremarried and continues to occupy the home.⁹

Conservation Use Value Assessment (CUVA)

If you own agricultural, timber, or conservation land, CUVA can dramatically lower your tax burden. Instead of being taxed on 40% of fair market value, qualifying land is taxed on 40% of its current use value, which is almost always far lower. The tradeoff is a 10-year covenant: you agree to keep the land in its qualifying use for a full decade.¹⁰

Eligible properties range from 10 to 2,000 acres. File the application with the Tax Assessor’s Office between January 1 and April 1. The covenant runs with the land, so it survives a sale and binds the new owner for the remaining years.

Breaking the covenant is costly: twice the difference between what you paid under the current-use assessment and what you would have paid at fair market value, calculated across every year of the covenant.¹⁰ A few exceptions reduce the penalty to just one year’s tax difference, including foreclosure, documented medical disability, or an owner aged 65 or older who has already renewed the covenant at least once and kept the property in qualifying use for at least three years after renewal.

Business Inventory: Freeport

If you own a business rather than just a home, Coweta’s Freeport exemption can reduce or eliminate taxes on certain inventory categories — raw materials used in manufacturing, finished goods held by the original manufacturer, and goods in a warehouse or fulfillment center destined for out-of-state shipment. The exemption percentage depends on the inventory type and the Freeport level the county has adopted. Filing on time matters: miss the June 1 deadline and the exemption is waived for the year. Business personal property itself is valued at 100% of cost as of January 1.

When Your Bill Is Due

Tax bills are mailed around October 1 to the owner of record as of January 1 of that tax year. The due date is generally December 1. If the due date falls on a weekend or holiday, you have until the next business day.¹¹ Check the specific date printed on your bill, since it can shift slightly year to year.

Pay online at cowetataxcom.com (a convenience fee applies to electronic payments) or mail a check to the Tax Commissioner’s office in Newnan with the bill coupon so payment is applied to the correct parcel. Every bill breaks down how your tax dollars are split between the county government, the school district, and any municipal levy. Review those line items before paying to confirm your exemptions are reflected and your property classification is right. Catching an error before you pay is far easier than getting a refund later.

What Happens If You Don’t Pay

Missing the due date triggers two separate consequences. Interest accrues monthly at a rate equal to the Federal Reserve bank prime loan rate plus 3%, recalculated each January.¹² Then, 120 days after the due date, a 5% penalty on the unpaid balance is added, and another 5% is added every 120 days after that, capped at 20%.¹¹

If taxes remain unpaid, the Tax Commissioner can issue a tax execution (a fi. fa.), creating a lien against your property. Before issuing the execution, the commissioner must send written notice and allow 30 days for payment.¹³ After the lien is filed, the property can eventually be levied and sold at public auction, with title research and advertising costs added to the delinquent account.

If your home is sold at a tax sale, you have 12 months from the sale date to redeem it. Redemption means paying the purchaser what they paid at auction, plus a 20% premium for the first year and any taxes the purchaser has paid in the interim.¹⁴ After the 12 months expire, the purchaser can foreclose the right of redemption and take full title.¹⁵ A single year of missed taxes can cascade into losing your home.

How to Appeal Your Assessment

Exemptions aren’t the only way to lower your bill. If you believe the Board of Assessors overvalued your property, you have 45 days from the date the assessment notice was mailed to file a written appeal using Form PT-311A.¹⁶ File it with the Coweta County Board of Tax Assessors, not the Georgia Department of Revenue. If the county has adopted an electronic filing policy, you can email it.

Once the Board of Tax Assessors receives your appeal, it has 180 days to review. If they agree with you, they’ll correct the value. If they don’t respond within 180 days, the value you asserted on your appeal automatically becomes the assessed value for that tax year.¹⁷ That 180-day default is one of the stronger protections in Georgia property tax law.

If the Board of Tax Assessors upholds the original value, the appeal moves to the county Board of Equalization, a citizen panel independent of the assessor’s office. The board can rule on value, on whether the assessment is uniform compared to similar properties, and on whether the property qualifies for an exemption.¹⁷ Either side can appeal that decision to the Superior Court of Coweta County. Some homeowners hire property tax consultants who work on contingency and take a percentage of the savings they achieve; whether that cost makes sense depends on the dollar amount in dispute.
