Relating to the calculation of certain ad valorem tax rates.

SB 1023 requires Texas local taxing units (like cities and counties) to calculate property tax rates using electronic forms that accurately reflect certified property values from appraisal rolls. The bill mandates that these forms must include hyperlinks to supporting documents for each tax calculation entry (excluding math), be compatible with state tax databases, and separately calculate rates for each reinvestment zone within the taxing unit. It applies to tax years beginning January 1, 2026, and updates existing tax code sections to enforce these electronic submission standards. This bill directly affects how local governments compute and submit property tax rates, ensuring greater transparency and accuracy in the calculation process.
