Clayton County Property Tax Appeal, Georgia
Clayton County is located in the north-central portion of Georgia, just south of Atlanta, serving as one of the core counties of the Atlanta metropolitan area. The county seat is Jonesboro, with Forest Park being the largest city, and other notable cities include Riverdale, College Park, Morrow, Lake City, and Lovejoy. Clayton County faces a significant property tax burden with a median effective property tax rate of 1.44%, substantially higher than the national median of 1.02%. The median annual property tax bill of $2,787 exceeds the national median of $2,400 by $387, making property tax appeals particularly valuable for homeowners seeking relief. With property values assessed annually and recent millage rate increases of 31.11% in 2024, many Clayton County residents are overpaying on their property taxes.

On the typical Clayton County home, valued near $203,200 at the county’s effective tax rate of 1.44%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.
2026 Appeal Deadline: 45 days from the date printed on the Notice of Assessment
The 45-day deadline begins from the printed date on your Notice of Assessment, not the date you receive it. For 2026, the expected deadline is August 14, 2026, based on typical late April mailing of assessment notices. This deadline is strictly enforced by Georgia law and is non-negotiable. If your appeal is not filed or postmarked by the end of this 45-day window, you forfeit your right to appeal for that tax year.

How Clayton County Assesses Property
Assessed by: Clayton County Board of Tax Assessors
Assessment cycle: annual
Notices typically mailed: Late April
In Clayton County, residential property is assessed at 40% of its Fair Market Value (FMV), which is the standard assessment ratio for Georgia. The Board of Tax Assessors determines your property's fair market value as of January 1 each year based on factors such as square footage, property condition, location, and recent sales of comparable properties. If your home's market value is $203,200 (the county median), at Georgia's 40% assessment ratio your assessed value would be $81,280, resulting in approximately $2,787 in annual taxes at the county's effective rate of 1.44%.
The Appeal Process
Appeals are heard by the Board of Equalization. The Board of Equalization is a panel of trained citizen volunteers who conduct a public hearing where you can present your evidence clearly and concisely. Bring all documentation including comparable sales, photos, repair estimates, and any third-party appraisals to support your claim that the county's assessed value is too high.
Step 1: Review your Annual Notice of Assessment carefully when it arrives (typically late April). Note the fair market value, assessed value (40% of FMV), any exemptions applied, and the critical 45-day appeal deadline printed on the notice.
Step 2: Gather supporting evidence including recent comparable sales from similar homes in your neighborhood (ideally sold within 6-12 months prior to January 1), photos showing your property's actual condition including any depreciation or defects, repair estimates for needed maintenance, and documentation of any incorrect assessor data such as wrong square footage, room count, or features.
Step 3: Complete Form PT-311A and submit your appeal via the online portal, certified mail, or in-person delivery to the Clayton County Board of Assessors within the 45-day deadline. Select your preferred hearing option: Board of Equalization (most common), Arbitration (for valuation disputes), or Hearing Officer (for non-homestead properties over $500,000).
Step 4: The Board of Assessors will conduct an initial informal review of your appeal. They may agree and lower your value, schedule an informal conference to discuss your evidence, or uphold the original appraisal and forward your case to the Board of Equalization.
Step 5: If forwarded to the Board of Equalization, attend your hearing where a panel of trained citizen volunteers will review your evidence. Present your comparable sales, photos, and documentation clearly and concisely. The BOE will issue a written decision.
Step 6: If you disagree with the Board of Equalization's decision, you have 30 days to appeal to Clayton County Superior Court. Either party can appeal the BOE's decision within this timeframe.
Step 7: If a successful appeal reduces your assessed value, you receive a three-year assessment freeze under Georgia's 299c provision, protecting you from assessment increases for three consecutive years across both school and county taxes.
