The median Duluth homeowner pays $3,826/year in property taxes. That is 4.01% of median household income. See how Duluth compares and check your savings potential.
Duluth built its identity around a downtown many Gwinnett suburbs never had, with a Town Green, a historic rail depot, the Southeastern Railway Museum, and blocks of restaurants reflecting one of the most international populations in Georgia. That draw shows up in prices. The typical Duluth home is worth about $400,800, around 5 percent above the Gwinnett County median of $380,900, and the city of 32,426 keeps adding townhomes and infill that push values in both directions. Gwinnett's effective property tax rate sits near 1.40 percent, and for households earning Duluth's median income of $95,331, property taxes absorb roughly 4 percent of household income each year, a larger bite than most homeowners register until they map it against take-home pay. Assessment accuracy matters more in a market this varied. The middle band of Gwinnett County home values reaches from roughly $289,831 to $487,646, and Duluth alone contains 1980s swim-and-tennis subdivisions, gated golf communities, aging condos, and brand-new townhomes. County models that average across those segments can assign your 40-year-old house the trajectory of new construction a mile away, and nobody at the assessor's office will catch the mismatch for you. Comparing your notice value against recent sales of genuinely similar homes is the only way to know whether yours is fair. If the number is high, you can appeal. Georgia law sets the appeal deadline at 45 days from the date of your assessment notice. The date printed on your notice controls. Confirm with your county before you file.
Duluth Appeal Quick Facts
The median home in Duluth is valued at $400,800, and the typical homeowner pays about $3,826 per year in property tax (Census ACS 2024), based on Gwinnett County's 3.506% combined millage applied to 40% of fair market value after exemptions. That means the typical Duluth homeowner spends 4.01% of household income on property taxes alone. If Gwinnett County has overestimated your home's fair market value, you are paying more than you should. Filing is free, and the Board of Equalization can lower your value but cannot raise it above the county assessors' figure, except on a value already frozen by an earlier appeal. At $400,800, Duluth home values are 5% above the Gwinnett County median, 135% above Georgia's statewide median of $170,200, 26% above the national median of $318,000.
Check If Your Duluth Home Is Overassessed
Peachtree Corners leads Gwinnett County in home values, but your individual assessment could still be too high regardless of where Duluth falls in the county ranking.
With a population of 32,426, Duluth has plenty of recent sales to draw from. 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. Focus on per-square-foot price comparisons and adjust for differences in lot size, condition, and amenities. For the full evidence strategy, exemption details, and step-by-step filing instructions, see our Gwinnett County Property Tax Guide.
Based on a combined tax rate of 3.506%. Your actual rate may vary by tax district. Three-year figures are estimates and apply only if your value is reduced; you can then keep saving for up to three years, subject to the statutory exceptions.
A 10% reduction on the median Duluth home ($400,800 down by $40,080) would save approximately $562 per year, or $1,686 over three years (estimated, subject to the statutory exceptions) with the 299c value freeze.
At 4.01% of household income, even a modest reduction in your assessed value makes a real difference in your annual budget.
