Rate Breakdown

Property taxes in Clayton County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Clayton County

Clayton County follows the statewide Georgia system of property taxation. Each year the county tax assessor determines the assessed value of every taxable parcel by applying a uniform assessment ratio—typically 40 % of the property's fair market value for residential homes. Commercial, industrial, and agricultural properties may have different ratios, but the process is the same: the assessor appraises the market value, multiplies it by the appropriate ratio, and records the result as the assessed value.

Once the assessed value is set, the county multiplies it by the applicable millage rate. One mill equals one‑tenth of one percent (0.001) and represents the amount of tax you pay per $1,000 of assessed value. Clayton County’s general millage rate changes annually based on budget needs, and additional millages may be levied by the City of Jonesboro, the Georgia State Schools, special districts, or voter‑approved bonds. Your total tax bill is the sum of all millages applied to your assessed value:

• Assessed Value × (Total Millage Rate ÷ 1,000) = Annual Property Tax

For example, a home assessed at $120,000 with a combined millage of 45 mills would owe $5,400 per year (120 × 45 ÷ 1,000).

Available Exemptions

Georgia offers several exemptions that can lower the taxable portion of your property. In Clayton County you may qualify for one or more of the following:

• Homestead Exemption – Reduces the assessed value of a primary residence by up to $2,000. The exemption is automatic for owners who occupy the property as their main home.
• Senior Citizen Exemption – Residents age 62 or older may receive a $2,000 exemption, plus an additional $1,000 if the homeowner’s total income is below the state‑defined threshold.
• Disability Exemption – Qualified individuals with a documented physical or mental disability can claim an exemption of up to $2,000.
• Veteran Exemption – Veterans who served in the U.S. armed forces and meet residency requirements may receive a $2,000 exemption; disabled veterans qualify for an extra $2,000.

All exemptions must be applied for on the annual “Property Tax Rebate and Exemption Application” (Form 500) and are subject to verification by the county tax commissioner’s office.

Payment Schedule & Deadlines

Clayton County property taxes are due in two installments:

• First installment – Due November 1; a $25 penalty is added on November 2 if unpaid.
• Second installment – Due February 1 of the following year; a $25 penalty is added on February 2.

Taxpayers may also elect to pay the full amount by the November deadline to avoid any penalties. Payments can be made online through the county’s e‑Pay portal, by mail using the provided voucher, or in person at the tax collector’s office.

If a payment is missed, a daily delinquency surcharge of 0.5 % accrues after the 30‑day grace period, and the account may be placed in tax‑sale proceedings. To avoid these consequences, contact the tax collector as soon as possible to arrange a payment plan or request a hardship waiver.

Appealing Your Assessment

If you believe your property has been over‑assessed, you have the right to appeal:

• Step 1 – Review the Assessment – Obtain a copy of the assessment notice and compare the fair market value with recent sales of comparable properties.
• Step 2 – File a Formal Appeal – Submit a written appeal to the Clayton County Board of Equalization within 30 days of the assessment notice. Include supporting evidence such as appraisals, sales data, or photographs.
• Step 3 – Attend a Hearing – The Board will schedule a hearing where you may present your case. An appointed hearing officer will render a decision, typically within 60 days.
• Step 4 – Further Review – If dissatisfied with the Board’s decision, you may request a review by the State Board of Equalization or pursue judicial review in state court.

Timely filing and thorough documentation are crucial; missing the 30‑day deadline generally forfeits your right to contest the assessment for that tax year.
