At the county's effective tax rate of 0.98%, this would result in approximately $3,387 in annual property taxes before any exemptions are applied.

The application deadline is April 1 each year, and once granted, the exemption renews automatically as long as the property remains your primary residence.
What happens at a Board of Equalization hearing in Gwinnett County?
A Board of Equalization hearing in Gwinnett County is conducted before a three-person citizen panel appointed by the county to hear property tax appeals. The hearing is typically scheduled 3-4 weeks in advance by the Clerk of Courts, giving you time to prepare. You'll have 10-15 minutes to present your evidence and explain why you believe your property's assessed value is too high.

If you're unsatisfied with the Board's decision, you have 30 days to request a Settlement Conference or 20 days to appeal to Superior Court.
How much can I save by appealing my property taxes in Gwinnett County?
The potential savings from a successful Gwinnett County property tax appeal depends on how much your assessed value is reduced. For example, if you successfully reduce your home's market value from $400,000 to $375,000, your assessed value drops from $160,000 to $150,000 (at the 40% ratio), saving approximately $98 annually at the 0.98% effective rate before considering exemptions. However, the real value comes from Georgia's three-year assessment freeze under O.C.G.A. § 48-5-299(c), after a successful appeal, your reduced assessed value is frozen for three years, multiplying your annual savings by three. For a $25,000 market value reduction, you could save nearly $300 over the three-year freeze period. The higher your property value and the larger your reduction, the more you save, making appeals particularly worthwhile for homes valued above the county median.
What evidence do I need for a Gwinnett County property tax appeal?
The strongest evidence for a Gwinnett County property tax appeal is comparable sales data showing recent sales of similar homes in your neighborhood that support a lower value than your assessment. Focus on finding 3-5 properties that sold within the past 12 months, located in your subdivision or immediate area, with square footage within 10-15% of your home's size. Additional compelling evidence includes photographs documenting property condition issues, needed repairs, or functional problems that affect value; contractor estimates or invoices for significant repairs or damage; a professional appraisal conducted within the past year; and data showing your assessment is higher than similar neighboring properties (uniformity argument under Georgia Code § 48-5-311). You can access recent sales data and neighborhood information through the Gwinnett County Assessor's property search portal at www.Gwinnett-Assessor.com using the 'Recent Sales in Area' or 'Comp Report Generator' tools.
Can my property taxes increase if I file an appeal in Gwinnett County?
Yes, Georgia is one of the few states where a property tax appeal can result in your assessed value being increased rather than decreased. Under Georgia law, if the Board of Assessors finds during the appeal process that your property is undervalued compared to fair market value, they may counter-appeal and raise your assessment. This risk makes it critical to only file an appeal when you have solid comparable sales evidence demonstrating your property is genuinely overvalued. You should never appeal based solely on hoping for a reduction without supporting data. Despite this risk, most homeowners with legitimate evidence of overvaluation successfully obtain reductions. Working with experienced professionals who understand Georgia's appeal process can help minimize the risk of a counter-appeal while maximizing your chances of success.
How long does the property tax appeal process take in Gwinnett County?
The complete property tax appeal process in Gwinnett County typically takes 3-9 months from filing to final resolution, though timelines vary based on the appeal volume and complexity of your case. After you file, the Board of Assessors' appraisal staff conducts an initial review, which may result in an Amended Notice of Assessment if they agree to adjust your value, this can happen within a few weeks. If staff doesn't agree to a reduction, your case advances to the Board of Equalization, with hearings typically scheduled 3-4 weeks in advance. The Board issues a written decision within 10 days of your hearing. If you pursue further appeals through a Settlement Conference or Superior Court, the process extends significantly longer. While your appeal is pending, you must still pay your property tax bill by the October 15 due date to avoid penalties, though you'll receive a supplemental bill or refund once the appeal is resolved.
