1️⃣ Understand the Reason for the Increase

Review Your Annual Notice of Assessment: This notice should provide a reason for the change in value, such as "market increase," "property improvements," or "correction of prior error."
Compare with Previous Years: Assess how this year's valuation compares to prior years. A sudden large jump may indicate an issue.
Consider Recent Improvements: Reflect on any significant additions or renovations to your property that might justify an increase.

⏰ Act Quickly – The 45-Day Deadline

Mark the Date: You have 45 days from the date printed on your Annual Notice of Assessment to file an appeal with the Gwinnett County Board of Assessors. Missing this deadline severely limits your options.

📂 Gather Evidence to Support Your Challenge

You'll need to build a case based on one or more of the following grounds for appeal:

💰 Overvaluation (Fair Market Value)

Comparable Sales (Comps): Research recent sales (within the last 6-12 months prior to January 1st of the tax year) of properties similar in size, age, style, location, and condition.
Photos and Documentation of Property Condition: If your property has issues (deferred maintenance, damage), take clear photos and obtain repair estimates.
Independent Appraisal: A recent appraisal by a licensed appraiser can serve as strong evidence.
Recent Purchase Documents: If you bought the property recently for less than the assessed value, provide your closing statement.

⚖️ Lack of Uniformity

Assessment Data of Comparable Properties: Find the assessed values of similar properties in your neighborhood on the Gwinnett County Tax Assessor's website. Compare their characteristics and assessed values per square foot to yours.
Photos of Your Property and Comparables: Highlight similarities in condition and features.

🛠️ Errors in Property Information

Survey: If the lot size is incorrect.
Blueprints or Floor Plans: If the square footage is inaccurate.
Photos: To show the absence of a feature the county records indicate.Gwinnett County+1Hallock Law LLC | Property Tax Appeals+1

🔀 Choose Your Initial Appeal Option

Hearing Officer: For certain high-value commercial properties.madlivewynwood.com

For a sudden increase in residential property value, appealing directly to the Board of Assessors is a common first step.

📬 Await the Outcome of the Initial Review

"No Change" Letter: The county upholds its original assessment. Decide whether to proceed to the Board of Equalization.
"30-Day Letter" (Amended Notice Value): The county offers a revised value. You have 30 days to accept or reject this. If you reject it, your appeal moves to the next level.

🏛️ Prepare for a Board of Equalization Hearing (If Necessary)

Organize Your Evidence: Present your case clearly and concisely with supporting documents.
Submit Evidence: Submit your evidence to the BOE at least 7 days before the hearing. Check specific instructions provided by the county.
Attend the Hearing: Be prepared to explain why you believe the assessment is incorrect.

🧠 Key Strategies for Challenging a Sudden Increase

Focus on Market Changes: If the sudden increase doesn't align with actual market trends in your neighborhood, emphasize this with comparable sales data.
Look for Errors: A significant jump could be due to an error in the property's characteristics. Verify all details on your assessment notice.
Highlight No Recent Improvements: If the increase seems tied to improvements you haven't made, provide evidence to that effect.
Act Immediately: Don't wait until the last minute to file your appeal.

🧾 Important Considerations

Tax Bill During Appeal: You will likely receive a tax bill even while your appeal is pending. It's crucial to pay the temporary bill (usually the lesser of 85% of the current assessment or 100% of the previous year's) by the due date to avoid penalties and interest. If your appeal is successful, you'll receive a refund.
Professional Help: For complex situations or high-value properties, consider consulting with a property tax consultant or attorney specializing in appeals.

By understanding the process, gathering strong evidence, and acting within the deadlines, you can effectively advocate for a fair assessment of your property in Gwinnett County.
