If you feel that your property valuation is too high and you have received an assessment notice for 2009, you can start the appeal process by completing and timely mailing or hand-delivering an "Appeal Letter", to the Board of Assessors' Office at 75 Langley Dr., Lawrenceville, GA 30045. Once the "Appeal Letter" is filed, the appraisal staff will review your valuation to determine if any adjustments should be made.

How do I start the process?

1. Watch for arrival of your assessment notice sometime in April 2009. The assessment notice will indicate the results of the appraisal review and will allow you to begin the appeal process.
2. If you disagree with the value indicated on the Notice of Change of Assessment, you have the right to appeal. Georgia's Property Tax Statutes states "the time for filing [a] notice of appeal shall be 30 days" from the date of the change of assessment notice. Appeals must be made in writing and either hand-delivered to our office or USPS postmarked within the 30-day period there are no exceptions.
3. The assessment notice will explain how to make an appeal. If you have questions about assessment notices, please read the list of frequently asked questions (FAQs) found at the end of this article.
4. If you appeal the valuation on the assessment notice, we will make a further adjustment and send you a revised notice, or your appeal will be forwarded to the next level, the Board of Equalization.

If you have any questions please read the list of frequently asked questions (FAQs) or please feel free to contact the Tax Assessor's Office at 770.822.7200 or assessor@gwinnettcounty.com.

Georgia law and Department of Revenue regulations require the local county Board of Tax Assessors to maintain taxable values at a minimum of 90 percent (on average) of actual market value.

Gwinnett County's last countywide update project occurred in 1999. The Property Appraisal staff spent more than 18 months and $700,000 on a program to validate property characteristics and revalue all classes of property in the county. Countywide property reappraisals are very expensive and resource-intensive. On the other hand, periodic value updates are more cost effective and are better handled by the in-house appraisal staff. Furthermore, most people interviewed would rather see more frequent smaller increases to their property valuation than infrequent large increases.

Every year we review sales by area or neighborhood. If the there is an indication based on sales that that our appraised values are out of line with what properties are generally selling for we then select that neighborhood or area to update the valuations to market. For 2008 approximately 55,000 change of assessment notices for real property were mailed in three (3) separate mailings. Of these assessment notices, approximately 40,000 parcels were selected for a value update and 15,000 were due to growth in the county.

On April 3, 2009, the Gwinnett County Board of Tax Assessors will mail approximately 68,000 real property Notices of Change in Assessment. This is the first of 3 notice mailings expected to reach a total of 75,000. Approximately 65,000 of the notices are from value updates and the remaining 10,000 notices result from new construction and tax returns filed.

"The appraisal staff has been working diligently to review all sales to select the best course of action to take on every neighborhood, area or property type. We have considered foreclosures and bank sales in the 2009 valuation process. We have reviewed the market transactions in all of the County's 1,400 neighborhoods and have made changes where indicated. Most property owners receiving notices will see value decreases for 2009."

60,000 of the notices issued for residential property will show an average value decrease of 11% or $25,000 of market value. The sum of all of the decreases for residential property is approximately $1.5 billion of market value.

We had previously seen a marked increase in the number of Real Property Tax Returns filed before the March 1 deadline. "Almost 45% of the Property Tax Returns received were within neighborhoods already being adjusted downward for 2009"

Appeals from the Notices of Change in Assessment must be filed within 30 days from the date on the notice. All appeals must be in writing and either USPS stamped or hand delivered within the 30 day period. Once the appeal is filed a staff appraiser will review the additional information, make changes if necessary and the Board will notify the property owner the results of the appeal review.

The deadline to appeal the valuations contained in the notices will be 30 days from the date of the notice. The assessment notices will explain how to make an appeal. If you have questions about the assessment notices, please read the list of frequently asked questions (FAQs).
