Relating to the calculation of certain ad valorem tax rates of a taxing unit and the manner in which a proposed ad valorem tax rate that exceeds the voter-approval tax rate is approved; making conforming changes.

HB 250 changes how local governments calculate property tax rates and establishes a new process for approving tax rate increases that exceed the rate previously approved by voters. This bill directly affects taxing units like cities, counties, and school districts when they seek to raise property taxes beyond voter-approved limits. The key provision requires a specific approval method for these higher tax rates, including potential public hearings or additional voting requirements. It also includes adjustments to related tax laws to ensure consistency with these changes.
