Property tax varies dramatically across Atlanta's 55+ community counties. Spalding County (Sun City Peachtree) runs ~1.42% effective — nearly double Cherokee County's ~0.79%. Real millage math, 65+ senior exemptions, and the floating homestead cap explained.
When comparing 55+ communities in Atlanta, most buyers focus on HOA fees and home prices. The property tax difference between counties is often larger than the HOA difference — and compounds over decades. On a $400K home, the gap between the highest-rate county (Spalding) and the lowest (Greene) is approximately $2,800/year. Over 20 years that is $56,000 in additional taxes.
Georgia property tax mechanics: assessed value = 40% of market value. Millage rate applied to assessed value. One mill = $1 per $1,000 of assessed value. Homestead exemption filed by April 1 of first year as primary resident reduces assessed value.

House Bill 581, signed 2024, creates a floating homestead exemption that caps annual increases in assessed value at the lower of 3% or the inflation rate for homesteaded properties. This is particularly valuable in high-appreciation markets — it prevents assessment from rising faster than inflation after your first year of homestead. File the homestead exemption by April 1 of your first year of residency.
Spalding County voters considered additional senior homestead exemptions in late 2025. Verify current senior exemption status with the Spalding County Tax Commissioner before purchase at spaldingcountytaxga.com.
