Filing a Clayton County Property Tax Appeal: A Step-by-Step Guide

If you believe your Clayton County, Georgia property tax assessment doesn't accurately reflect your home’s fair market value, the good news is you have the right to appeal. This guide walks you through each step of the Clayton County property tax appeal process, from understanding your assessment to potentially presenting your case to the Board of Equalization (BOE).

✅ Step 1: Review Your Annual Notice of Assessment

When to Expect It:
The Clayton County Board of Assessors typically mails Annual Notices of Assessment in late April each year.

Key Items on the Notice:

• Fair Market Value (FMV): The estimated value of your property as of January 1.

• Assessed Value: 40% of FMV (standard for residential property in Georgia).

• Exemptions Applied: Any homestead or other exemptions granted.

• Deadline to Appeal: This is 45 days from the date printed on the notice.

• Instructions for Filing an Appeal: Your notice will include how to appeal.

🛑 Important: This notice is not your tax bill, but it determines how much tax you’ll eventually owe.

✅ Step 2: Know Your Grounds for Appeal

In Georgia (and specifically in Clayton County), you may appeal your assessment on the following grounds:

1. Value: The FMV is too high.

2. Uniformity: Your property is assessed higher than similar nearby properties.

3. Factual Errors: Incorrect property information (square footage, bedrooms, features).

4. Denial of Exemption: You were wrongly denied a valid homestead or other exemption.

🚫 You cannot appeal just because you think your tax bill is too high—the appeal must be tied to the value or assessment accuracy, not the millage rate.

✅ Step 3: Gather Evidence to Support Your Appeal

To make a persuasive appeal, collect documentation such as:

• Comparable Sales (Comps):

  • Recent (within 6–12 months)

  • Similar location, size, age, and condition

• Independent Appraisal: Optional but often persuasive

• Photos/Videos: Especially for visible property issues

• Repair Estimates: For deferred maintenance or needed fixes

• Correction Documents: If county records are incorrect (e.g., wrong number of bathrooms)

• Exemption Proof: Deed, utility bills, or affidavits if your exemption was denied

✅ Step 4: Choose Your Method to File

You may file your appeal in one of three ways:

📲 Online (Recommended)
