Relating to the calculation of the petition election tax rate for certain taxing units and the ability of the voters to petition for an election to determine whether to reduce the ad valorem tax rate adopted by those taxing units to the petition election tax rate.

This bill changes how certain Texas taxing units (like hospital districts and junior college districts) calculate the tax rate voters can petition to reduce. It requires officials to use a specific formula from Section 26.076 to determine the "petition election tax rate" and mandates that all calculations must match certified property values in the county appraisal roll. Voters in these units can then petition for an election to lower the adopted tax rate to the calculated petition rate. The bill updates tax code procedures to standardize these calculations and ensure accuracy in the process.
