H.B. No. 5447 amends the Texas Tax Code to enhance the electronic processing and accuracy of ad valorem tax rate calculations. The bill requires that tax rate calculation forms be in an electronic format that allows for electronic completion and certification by designated officers. Notably, it mandates that these forms must now include a hyperlink to a document that verifies the accuracy of each entry, except for mathematical calculations. Additionally, the bill specifies that adjustments to property values and taxes for taxing units affected by the tax rate calculation must be calculated separately for each reinvestment zone in which the unit participates.

Furthermore, the bill stipulates that the designated officer or employee must utilize the prescribed tax rate calculation forms and include the required hyperlink in their calculations of the no-new-revenue tax rate and the voter-approval tax rate. The changes outlined in this bill will take effect on January 1, 2026, and will apply to tax years beginning on or after that date.
