An assessment in Gwinnett County, Georgia, may not tell the whole story about your property. Its condition, location, and comparable sales can all affect the case for a different value. Reviewing your assessment is a useful first step when the number does not seem to fit your home.
A Gwinnett County property tax appeal is a formal challenge to an assessment, with filing rules and evidence requirements specific to Georgia. Review your notice, confirm the applicable valuation date, and check the official local instructions before filing. The guide below brings together the county’s filing details, process, and resources so you can understand what preparation is involved.

Step 1: Find the notice date.
It is in the upper right corner of your Annual Notice of Assessment. Your 45 days start there, not on the day it arrived.
Step 2: Read the fair market value.
The notice shows a fair market value and the 40% assessed value derived from it. The appeal targets the fair market value.
Step 4: File Form PT-311A.
Online through the Board of Assessors portal, by mail to 75 Langley Drive, or in person. Not by email, not by fax.
Step 5: Settlement conference.
Georgia requires the assessors to offer a settlement conference after a notice of appeal. Many Gwinnett cases resolve here.
Step 6: Board of Equalization.
If the county does not move, a three-member panel of local property owners hears the case and rules on your comparable sales.
Step 7: The freeze.
A value reduced through appeal is generally held for the following two tax years under O.C.G.A. § 48-5-299(c).

In the meantime, here's general information about how a property tax appeal works in Gwinnett County. Check the county's official site for current deadlines and fees.
The Gwinnett County Board of Assessors mailed about 311,000 Annual Notices of Assessment in the 2026 cycle, all on a single day in May. No office values 311,000 properties by hand. It is done with mass appraisal software, and mass appraisal is a statement about a neighborhood, not about your house.
Georgia assesses at 40% of fair market value (O.C.G.A. § 48-5-7). The ratio is fixed statewide, so a Gwinnett County appeal is an argument about the fair market value the county assigned, not about the ratio applied to it.
Your appeal is due 45 days from the date in the upper right corner of the notice (O.C.G.A. § 48-5-311). In 2026 Gwinnett mailed on May 15 and the deadline landed on June 29. Different year, different dates — the notice is the authority.
Gwinnett is strict about the mechanics. Appeals go in online, by mail, or in person. The Board of Assessors does not accept appeals by email or fax, and mailed appeals must be postmarked by the deadline.
Gwinnett grew fast and unevenly. Subdivisions built five years apart sit on the same road, and an automated model that averages them will overvalue the older one. Add a home that has not been updated since the nineties, a lot backing onto Peachtree Industrial, or a floor plan the model treats as generic square footage, and the number on your notice can run well ahead of what the house would actually sell for.
Roughly 30% to 60% of properties nationally are over-assessed. About 5% of owners appeal.
Under O.C.G.A. § 48-5-299(c), a value changed through appeal is generally frozen for the next two tax years. In a county where values have been moving, that freeze is often worth more than the first-year reduction.
