HB 2553 modifies how the Texas Comptroller conducts ad valorem tax studies related to school district property values. It revises the criteria for determining whether a school district qualifies as an eligible school district in property value studies, eliminating the requirement that the appraisal district meet a specific scoring threshold in the Comptroller’s Property Value Study review. Additionally, it mandates an annual report summarizing findings from the appraisal district reviews, including data on the number of districts reviewed, compliance rates, and trends over time. These changes aim to improve transparency and oversight in property tax evaluations​.
