Owning property in Gwinnett County comes with annual property tax assessments that can sometimes feel higher than expected. If you believe your property has been overvalued, you have the right to appeal your assessment and potentially reduce your tax burden.
Here is a step-by-step guide to appealing your property taxes in Gwinnett County.

Step 1: Review Your Gwinnett County Assessment Notice
Each year, Gwinnett County sends assessment notices to property owners. This notice includes:
- The county’s estimated market value of your property
- The assessed value used for taxation
- Information about appeal deadlines
Carefully review the notice and compare the assessed value to:
- Recent sales in your neighborhood
- Your property’s current condition
- Any factors that may negatively affect value
If the assessed value appears too high, you may have grounds for an appeal.
Step 2: Understand Gwinnett County Appeal Deadlines
In Georgia, property owners typically have 45 days from the date on the assessment notice to file an appeal.
Missing the deadline may result in losing your opportunity to challenge the assessment for that tax year, so it is important to act quickly.
Step 3: Gather Supporting Evidence for Your Gwinnett County Appeal
Strong evidence can improve your chances of a successful appeal. Helpful documentation may include:
- Comparable property sales
- Recent appraisals
- Photos showing property damage or deferred maintenance
- Repair estimates
- Incorrect property record information
For example, if your home has outdated interiors, structural issues, or features that differ from neighboring homes, documentation can help support a lower valuation.

Being organized and presenting clear market evidence is important.
