A property tax rate near the national median

Morgan City's median effective property tax rate (0.95%, Ownwell) runs genuinely close to the national median (~0.99%). St. Mary Parish's own default combined millage runs roughly 99.3 mills, before Louisiana's real $75,000 homestead exemption -- an illustrative $135,000 home would owe roughly $596/year after that exemption.

Louisiana's flat 3% income tax, funded by a high sales tax

Louisiana's real, current flat 3% individual income tax (effective Jan. 1, 2025) applies in Morgan City exactly as statewide, funded in part by a sales-tax increase that pushed Morgan City's own combined rate to 10.25%.

Likely elevated insurance given coastal exposure

No Morgan City-specific premium figure was found this pass, but Louisiana's real, statewide $4,644-$7,304/year range applies, and this record discloses honestly that Morgan City's genuine coastal St. Mary Parish position likely places actual premiums toward the HIGHER end of that range -- partially offset by the city's real, documented 5-10% CRS flood-insurance discount.
