How to File Your Appeal Before the Deadline
Step 1: Review Your Assessment
As soon as you receive your assessment notice or it becomes available online, review it carefully. Check the property details (square footage, lot size, bedrooms, bathrooms, condition) and the assessed value. Compare your value to recent sales of similar homes in your area.
Step 2: Gather Evidence
Before the deadline, collect:
- Comparable sales: 3-5 similar homes that sold for less than your assessed value near the valuation date (January 1, 2026 (40% of fair market value))
- Property condition documentation: Photos, repair estimates, and notes on anything that reduces your value
- Equity comparisons: Similar properties in your area that are assessed lower than yours
- An independent appraisal if available
Step 3: File Written appeal to the County Board of Tax Assessors
Submit your appeal to the County Board of Tax Assessors, then Board of Equalization before the deadline. In most Georgia counties, you can file by mail, in person, or online. Include your evidence or a summary of why you believe your assessment is too high.
Step 4: Attend Your Hearing
Informal review: Contact the Board of Tax Assessors directly to discuss your value before filing a formal appeal.
Formal hearing: Board of Equalization hearing (3-person panel) or Hearing Officer.
Step 5: Further Appeals
If the initial appeal does not produce a satisfactory result, you can escalate to Superior Court. Each level has its own deadline, so act quickly.
