Ad valorem taxes; revise certain provisions regarding limitations on increases.

HB 830 revises Mississippi's rules limiting annual increases to property tax revenues (ad valorem taxes) for local governments. It allows counties and municipalities to exceed the standard 2% annual tax increase cap without holding an election by adopting a resolution, provided they stay within specific thresholds (e.g., not exceeding 20 mills total or a prior 10-year average). The bill also clarifies that school district taxes, road maintenance taxes, bond payments, and mandated new programs are excluded from the 2% limit. This directly affects county boards, city councils, and school districts when setting property tax rates. The changes aim to provide more flexibility for local governments to fund services while maintaining some fiscal restraint.
