(Lawrenceville, Ga., May 23, 2025) – The Gwinnett County Board of Assessors mailed approximately 308,000 annual Notices of Assessment to residential and commercial property owners today.  

State law requires that annual notices be sent to property owners advising them of the assessed value of their property as of Jan. 1. The Annual Notice of Assessment provides last year’s value and the 2025 value along with an explanation for any change in value from the previous year.

Roughly 84% of residential properties and 54% of commercial properties reflect new values this year. The Gwinnett County Assessors’ Office uses available market data to value each property in a manner that meets state regulations.

The Annual Notice of Assessment is not a tax bill but includes the value of the owner's property that is used in calculating taxes. The Board of Assessors recommends that property owners review their Annual Notice of Assessment to ensure it accurately represents their property and fair market value for Jan. 1, 2025. If property owners disagree with the 2025 value, they have 45 days from the date on their assessment notice to file an appeal online, in person or by mail.

Recent legislation created a new standardized state-wide assessment notice for 2025. House Bill 92 requires that the annual Notice of Assessment include estimates of the city, school board, and county rollback rates. A rollback rate is the tax rate that when applied to current year property values produces the same amount of tax revenue as was generated by the previous year’s property values.
