How much of my income goes to property taxes in Lilburn?
At the median, Lilburn homeowners pay 5.8% of their household income ($63,581/year) in property taxes. That is a significant burden -- a successful appeal directly increases your take-home.
How do Lilburn property taxes compare to Peachtree Corners?
Peachtree Corners leads Gwinnett County with a median home value of $484,700, compared to Lilburn's $329,700. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.
How is my Lilburn property tax bill calculated?

In growing cities like Lilburn, 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 Lilburn?
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 Lilburn, 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.
