A real, wide property tax disagreement

Tangipahoa Parish's own cited effective property tax rate carried a genuine, disclosed cross-source spread this pass: Ownwell cited approximately 0.87%, while tax-rates.org cited a much lower approximately 0.36% (a $477 median bill on a $133,400 home).

Louisiana's real flat 3% income tax

Louisiana's 2024 reform (effective January 1, 2025) replaced the old 3-bracket graduated income tax with a flat 3% rate, alongside a near-doubled standard deduction and full elimination of the corporate franchise tax.

The $75,000 homestead exemption still applies

Louisiana's real, statewide $75,000 homestead exemption applies in Hammond as elsewhere -- the first $75,000 of a primary residence's fair market value is exempt from parish/local property tax.
