Jefferson Parish's own low property tax rate

Harvey's effective property tax rate runs approximately 0.52%, the same parish-wide figure documented across this project's other Jefferson Parish records, with a median annual bill of approximately $1,312 on a $251,400 home.

Louisiana's flat 3% income tax, funded by a nation-highest sales tax

Louisiana's real 2024 tax reform (effective Jan. 1, 2025) set a flat 3% individual income tax rate, funded in part by raising the state sales tax to 5% -- pushing Louisiana's average combined state-and-local sales tax rate to a real, nation-highest approximately 10.11%.

A real, concrete flood-insurance discount unique to Harvey's own status

Because Harvey is genuinely unincorporated (a Jefferson Parish census-designated place, not its own municipal government), Jefferson Parish's real CRS Class 3 rating applies directly -- cutting flood-insurance premiums by approximately 35% starting October 1, a real, disclosed advantage distinct from this batch's incorporated sibling markets.
