Relating to the vote required by the governing body of a taxing unit to adopt an ad valorem tax rate that exceeds the voter-approval tax rate or authorize the issuance of tax bonds.

HB 5303 requires taxing units (like cities, counties, and school districts) to obtain higher voting thresholds to raise property tax rates above previously approved levels or issue certain bonds. Specifically, it mandates an 80% supermajority vote of a governing body to adopt tax rates exceeding voter-approved levels after a failed election, and a 60% supermajority for issuing general obligation bonds. These rules apply only to tax years starting January 1, 2026, and affect all taxing units governed by Texas law. The bill does not change current tax rates but sets new voting requirements for future rate increases or bond authorizations.
