Focus on per-square-foot price comparisons and adjust for differences in lot size, condition, and amenities.

How much of my income goes to property taxes in Duluth?
At the median, Duluth homeowners pay 4.01% of their household income ($95,331/year) in property taxes. That is a significant burden -- a successful appeal directly increases your take-home.
How do Duluth property taxes compare to Peachtree Corners?
Peachtree Corners leads Gwinnett County with a median home value of $484,700, compared to Duluth's $400,800. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.
How is my Duluth property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Duluth's median home ($400,800), the assessed value is $160,320. Multiply by Gwinnett County's millage rate of 3.506% to get your annual bill. In growing cities like Duluth, reassessments often outpace actual market conditions -- compare your assessed value per square foot to recent closed sales within 1 mile of your home.
What evidence wins a property tax appeal in Duluth?
The strongest evidence is 3-5 comparable sales -- homes similar to yours in size, age, and condition that sold recently for less than your assessed value. In Duluth, there are typically enough recent sales to build a strong case. Focus on per-square-foot price comparisons and adjust for differences in lot size, condition, and amenities.
Can my property tax go up if I appeal?
No. Georgia law (O.C.G.A. § 48-5-311) protects you: the county cannot raise your assessed value above what they originally set just because you filed an appeal. The Board of Equalization only rules on the disputed value. Worst case, your appeal is denied and you keep your current assessment -- your taxes will not increase as a result of appealing.
