Gwinnett County Property Tax Calculator
The Gwinnett County Assessor's Office values property annually across one of metro Atlanta's fastest-growing suburbs; school, city, and county levies then each get billed against that figure. As elsewhere in Georgia, filing the state's homestead exemption both trims taxable value and slows future growth for an owner-occupied home. Set the county field above to Gwinnett County, then supply a home value for a projection.

Frequently asked questions
How is property tax calculated in Gwinnett County?
The Gwinnett County Assessor's Office fixes your property's assessed figure, and separate millage rates from the school system, the city, and the county are each billed against it, combining into your total annual statement. Filing the homestead exemption knocks down that taxable figure and slows future growth for an owner-occupied home.
How do I appeal my Gwinnett County assessment?
A written case goes to the assessor's office within the deadline printed on your annual notice, escalating to the county Board of Equalization if that outcome doesn't settle it.
Does Gwinnett County offer a homestead exemption?
Yes — Georgia's homestead exemption applies to an owner-occupied primary residence in Gwinnett County, reducing taxable value and capping how fast assessed value can grow each year once it's filed.
Is Gwinnett County's rapid growth reflected in property tax?
Fresh construction gets valued at today's market price right away, so the county's fast growth shows up quickly in what newly built homes are assessed at, while an existing homesteaded owner is shielded somewhat by Georgia's annual growth cap.
