Coweta County Tax: Exemptions, Appeals, and Payments

Coweta County property tax bills are due by December 1 each year, and the Tax Commissioner’s office mails them at least 60 days before that deadline.¹ The amount you owe is based on 40% of your property’s fair market value multiplied by the current millage rate, which the Board of Commissioners and Board of Education set annually. Homestead exemptions can reduce that assessed value, and you have 45 days from the date on your annual assessment notice to challenge the valuation itself.

How Your Bill Is Calculated

The Coweta County Board of Tax Assessors sets the value of all taxable property based on its condition as of January 1 each year.² Under Georgia law, fair market value is the price a knowledgeable buyer would pay and a willing seller would accept in a genuine sale.³

Georgia taxes property at 40% of that fair market value, and the 40% figure is called the assessed value.³ A home with a fair market value of $300,000 therefore has an assessed value of $120,000. The county multiplies that assessed value by the millage rate to produce your bill. Because millage rates are set each year, the total can shift from one year to the next even if your value does not change.

Once valuations are finalized, the county mails an annual assessment notice showing the previous year’s value, the new proposed value, and a contact person in the Assessors Office.⁴ Property owners can also declare a proposed value by filing a return with the Assessors Office between January 1 and April 1.⁵

Homestead Exemptions That Lower the Bill

Homestead exemptions reduce the assessed value of your primary residence. To qualify, you must own and live in the home as of January 1 of the tax year.⁶ Second homes, rental property, and vacant land don’t qualify.

The state standard homestead exemption gives a $2,000 reduction from assessed value for state, county, and school taxes. In Coweta County, local legislation has replaced that with a $10,000 exemption on county maintenance and operations taxes.⁷

Senior Exemptions

Coweta County offers several age-based exemptions. The income-tested ones use a $10,000 household income limit for the prior year, but Social Security and retirement income below the Social Security maximum benefit (set at $99,648 for 2026) does not count toward that figure.⁷

Age 62 and older: a $10,000 exemption from school taxes, subject to the income test.⁸
Age 65 and older: a $4,000 state and county exemption under the income test, which Coweta has locally increased to $10,000 at the county level. A separate local exemption adds a $75,000 reduction from school taxes with no income limit.⁷
Age 71 and older: a local exemption providing a $100,000 reduction from school taxes with no income limitation.⁷

Disabled Veteran Exemption

Honorably discharged veterans with a service-connected disability can exempt up to $126,526 of their homestead’s assessed value from all property taxes in 2026.⁹ Qualifying conditions include a 100% VA disability rating, unemployability at the 100% rate, or loss of use of limbs or eyesight. The exemption extends to an unremarried surviving spouse or minor children as long as they continue to live in the home.¹⁰

How and When To Apply

Applications are available at the Coweta County Tax Assessors Office and require proof of residency, plus income documentation for the income-tested exemptions. You can file any time from the prior year through April 1 of the tax year, and Georgia also allows applications up to the end of the 45-day appeal window on your annual assessment notice.⁸ Once approved, most exemptions renew automatically each year unless your circumstances change. Miss the window and the exemption won’t apply until the following tax year, and you’ll owe the full amount for the current one.

Appealing Your Assessment

If you think your new value is too high, you have 45 days from the date your annual assessment notice was mailed to file a written appeal. The Board of Tax Assessors reviews it first and has up to 180 days to either make corrections or confirm the original value. If they don’t act within 180 days, the value you asserted on your appeal automatically becomes your assessed value for that year.¹¹

If the Board makes changes you still disagree with, you have 30 days from the date those changes are mailed to continue the appeal to the County Board of Equalization. If the Board makes no changes, your appeal moves to the Board of Equalization on its own. That three-member board schedules a hearing within 15 days of receiving your appeal, holds it 20 to 30 days after you’re notified, votes at the conclusion, and mails its decision by certified mail.¹¹

If your appeal is unresolved when tax bills go out, you’ll receive a temporary bill based on the higher of your declared value or 85% of the Assessors’ value. Once the appeal concludes, you’ll get a refund or owe the difference. You can appeal a Board of Equalization decision to Superior Court, or choose binding arbitration for value disputes instead of going through the Board of Equalization.

How To Pay

Bills are due December 1. If that date falls on a weekend or holiday, the deadline moves to the next business day. You can look up your bill on the Tax Commissioner’s website by searching your name or property address; you’ll need the Map/Parcel ID and account number from the bill to pay.

Online: the county’s payment portal accepts e-checks and credit cards, with a convenience fee.¹²
By mail: send a check or money order with the payment coupon from your bill to the Tax Commissioner at 87 Newnan Station Drive, Suite 100, Newnan, GA 30265.¹³
In person or drop box: the office takes payments during business hours, and a 24-hour drop box outside the building handles after-hours deliveries.

If you haven’t received a bill by late October, don’t assume it isn’t owed. Penalties and interest apply whether or not the notice reached you. Download a copy from the Tax Commissioner’s website or call the office to confirm the balance.

If You Miss the Deadline

After December 1 passes, the Tax Commissioner sends a written notice that your taxes are outstanding. If you still haven’t paid within 30 days, the office issues a tax execution, which is a lien recorded against your property on the county’s General Execution Docket.¹⁴

Interest accrues monthly from the original due date at the federal bank prime loan rate plus 3%, compounded each month.¹⁵ Even a partial month counts as a full month.

If the lien stays unpaid, the county can levy and sell the property at a tax sale. The levying officer must give 20 days’ written notice to the owner, any mortgage holder, the IRS (if federal liens exist), and other relevant agencies before advertising the sale.¹⁴ After a tax sale, the former owner has 12 months to redeem the property by paying the auction price plus 20% interest. If not redeemed in the first year, the interest climbs to 30% in the second year, 40% in the third, and so on, and any taxes the buyer pays after the sale get added to the redemption total.¹⁶

Personal Property Is Taxable Too

Property tax in Coweta County isn’t limited to real estate. Boats, aircraft, farm equipment, and mobile homes are also taxable, as are business inventory and fixtures.⁵ Ordinary household belongings are not normally taxed.

Owners of taxable personal property must file a return with the Board of Assessors between January 1 and April 1 each year declaring the property’s value.⁵ Mobile and manufactured home owners carry an added requirement: the current year’s mobile home tax must be paid in full before the required location decal is issued.
