New owners miss this more than any other step, because nothing at closing files it for you.
The rules
- In Georgia you may apply for a homestead exemption any time after the home becomes your primary residence, up to April 1 of the first year you want it. Not applying counts as waiving the exemption. Georgia Department of Revenue: County Property Tax Facts (Fulton; Forsyth), checked 2026-10-19
- Georgia's House Bill 581 (2024) created a statewide floating homestead exemption. It exempts any rise in a homestead's assessed value above its adjusted base-year value. The 2025 base is the 2024 assessed value, and from 2026 the base rises by an inflation rate (CPI-U) set by the Revenue Commissioner. It applies unless the county, city or school district opted out.
