Rate Breakdown

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

How Property Tax Works in Seminole County

In Seminole County, Georgia, property taxes are computed on the assessed value of real estate, which is determined twice a year—once on June 1 and again on December 1. The county’s Tax Assessor’s Office assigns a percent value to properties based on comparable sales, market indicators, and a uniform tax scale. Once the assessed value is set, the county multiplies it by the current millage rate—expressed in mills, or thousandths of a dollar—to arrive at the tax liability. The millage rate is a composite of county, school board, and other special district rates published in the annual “Property Tax Fee Schedule.” For example, if a property is assessed at $150,000 and the combined millage is 18.5 mills, the tax owed would be $2,775.

Because Seminole County shares its millage with the Conyers City and multiple school boards, taxpayers should review the most recent fee schedule to confirm constituent rates. The schedule is published in the County Recorder’s office and is also available online via the county’s official website. Assessed values are indexed for inflation, ensuring that properties keep pace with market growth while remaining independent of purchase price fluctuations.

Available Exemptions

Georgia offers several property tax exemptions that Seminole County residents can claim. These reduce the assessed value before the millage rate is applied.

• Homestead Exemption – Residents who occupy the property as their primary residence may receive a standard exemption of $5,000, lowered by an additional amount if the property is valued under $93,000. Eligibility requires filing a deed endorsement with the county recorder.
• Senior Citizen Exemption – Homeowners aged 62 or older who provide proof of age and meet income guidelines can receive a $2,000 exemption. The application is submitted alongside the homestead petition.
• Disability Exemption – Veterans or civilians with a documented disability may qualify for a savings of $1,000. Applicants must submit a certified disability statement from the VA, Department of Health, or military records.
• Veteran Exemption – Active duty and disabled veterans in Georgia may qualify for a $1,200 exemption, provided they meet veteran status documentation and residency requirements.

All exemptions are calculated against the assessment date value; therefore, determining eligibility at the time of your assessment is critical. The Tax Assessor’s office offers a step‑by‑step guide on how to complete the forms and submit required documentation.

Payment Schedule & Deadlines

Seminole County requires property taxes to be paid in two installments: the first by June 30 and the second by December 31 of the same year. The tax office automatically sends outreach notices containing the due amount, due dates, and accepted payment methods. You may pay in person, by mail, or electronically through the county’s online portal.

Interest accrues on late payments at a statutory rate of 1.5% per month, and non‑payment beyond 90 days can result in a tax lien that may affect your title record. However, the county offers a “late payment forgiveness” program for last‑minute taxpayers: if payment is received within 14 days of the due date, no interest is charged. To avoid any late penalties, plan to remit full amounts by the established deadlines or arrange payment with the county’s finance office for a considered installment plan.

Appealing Your Assessment

Should you believe your assessed value is too high, the appeal process in Seminole County is clear and time‑bound. Appeals must be filed with the County Assessor’s Office before the close of the opposition period—usually November of the same year as the assessment. The appeal can be made in writing, online, or in person, and must include Supporting documentation such as recent comparable sales, market conditions, or a formal appraiser’s report.

Once submitted, the appraiser will conduct a comparative analysis and adjourn a public hearing; if the appeal is denied, you may proceed to the Tax Appeal Board. The Board meets quarterly, allowing for a formal hearing, presentation of evidence, and the opportunity for the taxpayer to present witnesses. Successful appeals typically reduce the assessed value, consequently lowering your tax bill for the remainder of the year. All documents and procedural guidelines are available on the county’s website under “Assessment Appeals.”
