Clayton County Property Tax: Rates, Exemptions, and Appeals

Clayton County property tax is calculated by taking 40 percent of your property’s fair market value and multiplying it by the combined millage rate set by the county, the school board, and any city you live in. The Board of Assessors sets the value; the Tax Commissioner bills and collects. Bills are generally due December 20, and several exemptions can meaningfully reduce what you owe.

How Your Bill Is Calculated

Georgia law defines fair market value as the price a knowledgeable buyer and willing seller would agree on in a genuine transaction.¹ The Board of Assessors sets that figure each year for every taxable parcel based on sales data, property characteristics, and local market conditions.

You aren’t taxed on the full value. Your taxable assessed value is exactly 40 percent of fair market value.² A home worth $250,000 has an assessed value of $100,000. A $350,000 home is assessed at $140,000.

That assessed value is then multiplied by the millage rate. One mill equals one dollar of tax per $1,000 of assessed value.³ If the combined rate is 30 mills and your assessed value is $100,000, the tax before exemptions is $3,000.

Who Sets the Rates

Three layers of government contribute to the total. The Clayton County Board of Commissioners sets the county rate for general operations. The Clayton County Board of Education sets the school rate, typically the largest single component. Cities within the county, including Jonesboro, Riverdale, Forest Park, and Morrow, add their own rates for residents inside city limits.⁴

Each authority adopts a new rate annually based on budget needs, and the Tax Commissioner applies the current rates when generating your bill. Your annual bill breaks down each authority’s share, and the current combined rate is also published on the Georgia Department of Revenue’s millage rate page.

Exemptions That Lower Your Bill

The homestead exemption is the most widely used way to reduce a Clayton County property tax bill. To qualify, you must own the property and live in it as your primary residence on January 1 of the tax year.⁵ The statewide baseline reduces your assessed value by $2,000 for county and school tax purposes.

Applications are due by April 1, or by the end of the 45-day window after you receive your annual notice of assessment, whichever is later.⁵ File with the Tax Commissioner’s office. Once approved, the exemption renews automatically as long as you keep living in the home. The $2,000 figure is a state minimum; Clayton County and its cities may offer additional local homestead exemptions on top, so ask the Tax Commissioner or Board of Assessors what applies to your parcel.

Seniors 65 and Older

A $4,000 exemption from all county ad valorem taxes is available if combined household income (you and your spouse) did not exceed $10,000 the prior year, excluding retirement income, pensions, and disability income up to the Social Security maximum benefit.⁵ Because Social Security and modest pension income are excluded, many retirees living on those sources will qualify.

Disabled Veterans and Their Survivors

Veterans rated 100 percent disabled by the VA, compensated at 100 percent for individual unemployability, or entitled to a statutory award for loss of limbs or sight can exempt the greater of $32,500 or the current federal maximum from all state, county, municipal, and school taxes. For tax year 2026, that federal maximum is $126,526. Unremarried surviving spouses and minor children of qualifying veterans get the same exemption.⁶⁷

Surviving Spouses of Peace Officers and Firefighters

If your spouse was a peace officer or firefighter killed in the line of duty, your homestead is fully exempt from all ad valorem taxes, covering state, county, municipal, and school taxes. This exemption replaces any other homestead exemption rather than stacking on top of it.⁸

Each of these requires an application, and some require documentation such as a VA disability rating, proof of income, or records of a spouse’s death in the line of duty. The homestead deadlines apply.

When and How to Pay

The default statutory due date in Georgia is December 20, though local governing authorities can adopt a different one.⁴ Confirm the exact date on your bill or the Tax Commissioner’s website, since it can shift.

The Tax Commissioner accepts several payment methods:

Online credit or debit card (Visa, MasterCard, Discover): 1.99 percent service fee per transaction. American Express is not accepted at this rate. You’ll need the seven-digit bill number from the top of your bill.⁹
Online e-check: flat $3.95 per transaction.⁹
Mail: check or money order to the Tax Commissioner’s Office in Jonesboro.
Drop box at the Tax Commissioner’s Office for after-hours payments.

The convenience fees go to the third-party processor, GovPros, LLC; the county receives none of it.⁹ If you owe for multiple years, the oldest year is paid first. There is no advertised installment plan for current-year taxes, so plan to pay the full amount by the due date.

What Happens if You Pay Late

A tax lien attaches to all property you own in Georgia on January 1 of each tax year, before any collection action begins. After the due date passes, the Tax Commissioner sends a written notice giving you 30 days to pay. If the bill still isn’t paid, the Tax Commissioner issues a tax execution, known as a fi. fa., against both you and the property.¹⁰

Once the execution issues, the county adds a levy administration fee of 5 percent of the delinquent tax or $250, whichever is less, with a $50 minimum.¹⁰ Interest accrues on the unpaid balance. If the debt still isn’t resolved, the county can levy and sell the property at public tax sale after the required notices to the owner, mortgage holder, and any lienholders.

Even after a tax sale, Georgia law preserves a right of redemption. For the first 12 months, the purchaser cannot disturb you or the property. To redeem, you repay everything the purchaser paid at sale, plus any taxes they’ve paid since, plus a 20 percent premium for the first year and 10 percent for each additional year. A $5,000 tax sale can climb past $6,000 within 12 months before the buyer’s added taxes are counted. Keeping current avoids the whole sequence.

How to Appeal Your Assessment

If you think the Board of Assessors overvalued your property, you have 45 days from the date your Annual Notice of Assessment was mailed to file an appeal.¹¹ Use Form PT-311A, the state’s uniform appeal form, and submit it to the Board of Tax Assessors by mail, in person, or by email if the county accepts electronic filing.

On the form, state your grounds: value, uniformity compared to similar properties, or taxability. You also pick your appeal path at the same time.¹²

The Board of Tax Assessors has up to 180 days to review and respond. If they agree the value should be lower, they correct it. If they fail to respond within that 180-day window, the value you asserted in your appeal automatically becomes the assessed value for that tax year.¹²

Board of Equalization

If the Board of Tax Assessors does not resolve the appeal, it moves to the Board of Equalization, an independent three-member panel. You can present comparable sales, independent appraisals, photos of defects, and other evidence supporting a lower value. All three members must be present, a majority decides, and the ruling comes in writing with reasons.¹²

Hearing Officer and Arbitration

Two other paths exist. A hearing officer, who must be a state-certified real property appraiser, is available only for non-homestead real property valued above $500,000, and only for disputes about value or uniformity. If the Clerk of Superior Court can’t find a qualified hearing officer, the appeal is redirected to the Board of Equalization.¹³ Arbitration is available for value disputes only and produces a binding decision.¹²

After any of these decisions, either side can appeal to Superior Court within 30 days. Most homeowners use the Board of Equalization; the hearing officer path is built for commercial and larger investment parcels where a specialized appraiser is worth the process.
