Ad valorem tax levy for school districts; provide levying authority with discretion to approve request by school board.

HB 393 would give school district tax authorities (like county boards) discretion to approve or partially approve school board requests for property tax increases. If a requested tax rate exceeds 55 mills or the current rate, the bill requires a public referendum before implementation. Exceptions include districts already levying above 55 mills or those needing tax hikes after declared disasters. This bill directly affects how Mississippi school districts seek funding through property taxes.
