Georgia Code 48-5-7 – Assessment of Tangible Property Exemptions come off the assessed value before the millage is applied, so filing for every exemption you qualify for is the single biggest lever you have over the final number.
How Your Tax Bill Is Calculated
The Coweta County Board of Assessors sets the fair market value of every property in the county.2Coweta County Tax Commissioner.

Georgia Code 48-5-2 – Definitions Only 40% of that figure is actually taxed. That reduced number is your assessed value.
A mill equals one dollar of tax for every $1,000 of assessed value.4Georgia Department of Revenue. Property Tax Millage Rates Here’s the math in practice. 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 rate is 21 mills, divide 21 by 1,000 to get 0.021, then multiply: $140,000 × 0.021 = $2,940 before any exemptions.
Current Millage Rates
Because the county, school district, and each city set their own millage every year during the budget process, the combined rate shifts from one tax year to the next. Before finalizing the rate, the county must publish it in a local newspaper and hold public hearings.5Justia. Georgia Code 48-5-32 – Publication by County of Ad Valorem Tax Rate
For a homeowner in unincorporated Coweta County, the bill combines the county government levy with the Board of Education levy.

Conservation Use Assessment for Ag and Timber Land
Owners of agricultural, timber, or conservation land can cut their tax burden through the Conservation Use Value Assessment (CUVA). 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 to keep the land in its qualifying use.10Justia. Georgia Code 48-5-7.4 – Preferential Assessment for Bona Fide Conservation Use Property
Eligible tracts run from 10 to 2,000 acres. Applications are filed 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 expensive: twice the difference between what you paid under current-use assessment and what you would have paid at fair market value, across every year of the covenant.10Justia. Georgia Code 48-5-7.4 – Preferential Assessment for Bona Fide Conservation Use Property A few exceptions cut the penalty to one year’s difference, including foreclosure, documented medical disability, or an owner 65 or older who has renewed the covenant at least once and kept the land in qualifying use for at least three years after renewal.

How to Appeal Your Assessment
If the Board of Assessors overvalued your property, you have 45 days from the date your assessment notice was mailed to file a written appeal on Form PT-311A.16Georgia Department of Revenue. PT-311A Appeal of Assessment Form File it with the Coweta County Board of Tax Assessors, not the state. If the county has adopted electronic filing, you can email it.
The Board of Tax Assessors then has 180 days to review the appeal. If they agree with you, they correct the value. If they don’t respond within 180 days, the value you asserted on the appeal automatically becomes the assessed value for that tax year.17Justia. Georgia Code 48-5-311 – Creation of County Boards of Equalization That default deadline is one of the strongest 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 schedules a hearing within 15 days of receiving the appeal and holds it within 20 to 30 days after notifying you. All three members must be present, and a majority vote decides. The board can rule on value, uniformity compared to similar properties, and whether the property qualifies for an exemption.17Justia. Georgia Code 48-5-311 – Creation of County Boards of Equalization Either side can appeal the Board of Equalization’s decision to the Superior Court of Coweta County.
