TAX/AD VALOREM TAX: Authorizes a taxing authority to levy a millage at a rate lower than the maximum authorized rate under certain circumstances (EN SEE FISC NOTE LF RV See Note)
HB 570 modifies Louisiana's property tax rules to allow local taxing authorities (like parishes, cities, or school boards) to adjust millage rates after reassessments. It permits elected bodies to raise rates up to the constitutional maximum with a two-thirds vote (no voter approval needed), while non-elected bodies face a 2.5% annual revenue cap on increases. Unspent rate allowances expire after 2024 (2023 for Orleans Parish), resetting to 2026 rates, and rates automatically decrease if reassessment increases property values. The bill directly affects local governments setting property taxes and property owners paying those taxes, effective January 1, 2027, pending constitutional amendment approval.

MODERATE
This bill updates Louisiana's tax laws to allow local taxing authorities to adjust their millage rates after property reassessments without permanently losing that ability if they choose not to raise taxes immediately. It distinguishes between elected and non-elected governing bodies, imposing stricter limits on non-elected groups regarding tax collection increases. The law also mandates that any unused maximum millage rates from Orleans Parish before 2024 must be permanently reduced.

The bill expands the scope by clarifying rules for both elected and non-elected governing authorities and specifically addresses the handling of unused millage rates in Orleans Parish.
