For example, if your home's market value is $373,300 (Gwinnett County's median), at Georgia's 40% assessment ratio your assessed value would be $149,320, resulting in approximately $1,627 in annual taxes at the county's effective rate of 1.09%.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Gwinnett County?
You have exactly 45 days from the date printed in the upper right corner of your Annual Notice of Assessment to file an appeal. This deadline is strictly enforced under Georgia law (O.C.G.A. § 48-5-311), and missing it means you cannot contest your property value for that tax year. Assessment notices are typically mailed in April or May, making most appeal deadlines fall in mid-June. The county will accept any letter of disagreement that identifies your property and is postmarked within this 45-day window.
How do I file a property tax appeal in Gwinnett County online?
Gwinnett County offers convenient online filing through their property appeals webpage at https://gwinnettcounty.com. You don't need a specific form - any letter of disagreement that includes your parcel number or property address will be accepted as a formal appeal. The online system allows you to track your appeal status after filing, though you should wait at least three days after submission before checking. For those preferring traditional methods, you can also mail your appeal to the Assessors' Office at 75 Langley Drive, Lawrenceville, GA 30046.
What is the homestead exemption worth in Gwinnett County?
The standard homestead exemption in Gwinnett County provides $10,000 off your assessed value for county taxes, $8,000 for school taxes, and $7,000 for recreation taxes. For a home at the county median value of $373,300, this translates to approximately $275 in annual tax savings. Additionally, Gwinnett offers a Value Offset Exemption that freezes your county tax at the base year value, protecting homeowners from tax increases due to rising property values. Senior citizens may qualify for even greater savings through the L5A exemption, which provides 100% exemption from school taxes.
What happens at a Board of Equalization hearing in Gwinnett County?
The Board of Equalization hearing is your opportunity to present evidence supporting a lower property value. Gwinnett County allows you to attend either in person at 75 Langley Drive or remotely via WebEx video conference. The county appraiser will present their case first, followed by your presentation. You should bring comparable sales data from similar properties in your neighborhood, photos documenting any property defects, repair estimates, and any other relevant evidence. The hearing typically lasts 15-30 minutes, and the Board will issue a written decision afterward.
How much can I save by appealing my property taxes in Gwinnett County?
Based on county data, approximately 43.5% of appeals are settled or withdrawn before the hearing stage, often resulting in reduced assessments. While specific reduction amounts vary, successful appeals in Georgia typically secure a three-year assessment freeze when a reduction is granted. For a median-valued home in Gwinnett County at $373,300 with annual taxes of $4,152, even a modest 10% reduction in assessed value could save you over $400 per year. With the three-year freeze, total savings could exceed $1,200 over the freeze period.
What evidence do I need for a Gwinnett County property tax appeal?
Successful appeals require strong supporting evidence, particularly comparable sales data from similar properties in your neighborhood that sold for less than your assessed value. The county's Property Information Search webpage provides access to neighborhood sales data you can use. Additionally, gather photos showing any property defects, professional repair estimates for needed maintenance, contractor bids for major repairs, and if available, an independent appraisal. Focus on properties with similar square footage, lot size, age, and condition that sold within the past year to build the strongest case.
Can I still pay my property taxes while my appeal is pending in Gwinnett County?
Yes, you must pay your property taxes even while your appeal is pending. Gwinnett County issues a partial temporary tax bill calculated at the lesser of 100% of prior year value or 85% of current year value, providing an automatic discount of at least 15%. This bill must be paid by the due date to avoid penalties and interest. Once your appeal is finalized, the Tax Commissioner will calculate any refund due or additional amount owed. If you have an escrow account, notify your mortgage company about the pending appeal to ensure proper payment.
What if I disagree with the Board of Equalization decision in Gwinnett County?
If you're unsatisfied with the Board of Equalization decision, you have 30 days to file an Appeal Continuance Form requesting a Settlement Conference with the Assessors' Office. During this conference, you can present additional evidence and negotiate directly with county staff. If the Settlement Conference doesn't resolve your appeal, you have 20 days to certify your appeal to the Clerk of Courts and pay the filing fee for a Superior Court appeal. The entire appeal process can take 3-9 months or longer, but persistence often leads to favorable outcomes.
