What a McIntosh County home really costs in property tax: the 2025 millage, Georgia's 40% assessment rule, and the exemptions that lower the bill. Unincorporated McIntosh County levies total about 29.35 mills.
McIntosh County is part of Momentum's Georgia coverage on the ScoutMLS (Golden Isles) system. Its 2025 digest rates: county maintenance & operations 11.500 mills, schools 16.200 mills; unincorporated parcels also carry industrial authority 1.650 mills. Inside a city the city's own millage applies instead of some unincorporated levies: Darien 3.100. All figures are from the Georgia Department of Revenue's 2025 County Ad Valorem Tax Digest.

City of Darien assesses at 100% of FMV - its 3.100 city mills apply to full market value, not the 40% base used everywhere else.
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 across all nine counties here. File once with the McIntosh County Tax Commissioner by April 1 and it renews while you own and occupy the home.
