HB 152 revises the Texas Education Code and Government Code to modify how property values are assessed in relation to school finance. Specifically, the bill updates the calculation for "taxable value" of school district property by accounting fully for optional homestead exemptions under Section 11.13(n) of the Texas Tax Code. This change ensures that the full amount of these exemptions is considered when determining the taxable value of property within a school district for state funding purposes, rather than only half of the exemption as currently applied.
