Sea Island SSD #5 adds 0.160; Jekyll Island district carries a 0.000 county levy (state-authority lease structure). Brunswick city parcels pay city 13.219 instead of the unincorporated SSD stack.
Georgia's homestead exemption reduces the assessed value each levy taxes. The statewide base exemption is modest, but counties and cities layer their own - senior, veteran, floating, and school-tax exemptions differ county by county, and since 2025 the statewide floating homestead (HB 581) caps assessment growth at inflation except where a jurisdiction opted out.
