S.B. No. 1051 amends the Texas Tax Code to refine the calculation of ad valorem tax rates for taxing units when property owners notify their intent to appeal appraisal review board decisions. Key changes include the requirement for tax rate calculation forms to be in an electronic format that can be certified and submitted electronically, as well as the inclusion of an addendum for documentation supporting any exclusions from the current total value due to anticipated substantial litigation. The bill introduces definitions for terms such as "anticipated substantial litigation," "associated business entity," "contested taxable value," and "uncontested taxable value," which clarify the context in which these terms will be applied.

Additionally, the bill mandates that property owners involved in anticipated substantial litigation must submit information regarding uncontested taxable values and their intent to pay taxes on those values. This submission must occur by a specified deadline, ensuring that the designated officers can accurately calculate tax rates. The changes will take effect for ad valorem tax years beginning on or after January 1, 2026, unless the bill receives immediate effect approval, in which case it would apply to tax years starting January 1, 2025.
