There is a trap in comparing property taxes across Gwinnett cities: the city millage rate is only one part of the bill.
A Gwinnett property can be taxed by county government, a school system, recreation and service districts, and a city. Some cities are billed on the county bill. Others send a separate city tax bill.
That means the lowest number on one table is not necessarily the lowest total tax burden.
For example, Gwinnett County’s 2026 millage table shows a county-billed total of 31.6 mills for several incorporated areas such as Lawrenceville, Duluth, Norcross, Snellville, and Suwanee. But the Tax Commissioner specifically marks those cities as places that bill their own city taxes separately.
Lawrenceville adopted a 2026 city millage rate of 3.26 mills and describes it as the lowest rate among Gwinnett’s full-service cities.
Snellville kept its city rate at 4.00 mills. Norcross adopted 6.249 mills. Suwanee’s FY2027 budget assumes a 4.93-mill city rate, with final adoption scheduled later in September 2026.
Other cities work differently. The county’s 2026 table shows a zero city-millage component on the combined county bill for Dacula and Peachtree Corners. That does not mean those homeowners pay no property tax; they still pay the applicable county and school levies.
Buford is especially difficult to compare with the rest of Gwinnett because it has its own school district. Gwinnett’s county tax table shows no Gwinnett County Public Schools millage for Buford, while Buford City Schools is funded through a separate city tax structure.
So which city is lowest?
If you mean the city-government millage rate among full-service Gwinnett cities that levy their own property tax, Lawrenceville currently points to its 3.26 mills as the lowest.
If you mean the lowest total annual property-tax bill, there is no honest countywide answer without comparing the exact parcel, school district, city tax, county service districts, exemptions, and any special district.
For home buyers, the best comparison is not “city rate versus city rate.” It is the estimated total tax bill for two specific properties at the same purchase price.
That is the only way to make an apples-to-apples comparison.
