Relating to the vote required in an election to approve an ad valorem tax rate that exceeds a taxing unit's voter-approval tax rate; making conforming changes.

HB 301 changes the voter approval threshold for local tax rate increases that exceed a community's existing voter-approved tax rate. Currently, a simple majority (over 50%) of votes is required, but this bill would raise that to a two-thirds majority. It amends Texas codes to update election notices, requiring clear comparisons of the proposed tax rate, the "no-new-revenue" rate, and the voter-approval rate. This directly affects cities, counties, and school districts seeking to raise property taxes beyond their current approved limits without holding an election.
