41% of Fulton County homes were overvalued in 2025. Here's how to read your notice and file before the deadline.
Your Fulton County 2026 Assessment Notice: What to Look For Fulton County assessment notices are expected to arrive in mid-June 2026, following a consistent pattern (June 9 in 2023, June 18 in 2024, June 17 in 2025). If the number on yours looks too high, the data suggests you may be right. The Fulton County Board of Assessors' own figures show that 41% of residential properties were overvalued in 2025.

The 40% ratio has a practical consequence for appeals: every $10,000 your home is overvalued translates to $4,000 in excess assessed value. That may look small on paper, but at a typical Georgia millage rate of 30-40 mills, it adds…
