Thibodaux property tax: where it goes
A Thibodaux house pays 1.165% of its taxable value in property tax. For a house at $232,500 of market value with the homestead exemption, that's about $1,835 a year.
Tax is levied on assessed value, which is 10% of fair market value for a home, less the homestead exemption where it applies.
The Lafourche Assessor's 2026 millage sheet was not found; the official 2025 parish rates are used with the city's adopted 2026 millage. Bills go out late in the year.
