Relating to the provision of funding under the public school finance system on the basis of property values that take into account optional homestead exemptions.

SB 2644 amends Texas law to change how school funding is calculated by adjusting the property value base used in the state's public school finance system. It defines "taxable value" to exclude certain homestead exemptions (like those under Tax Code Sections 11.13(b), (c), or (n)) and captured appraised value in reinvestment zones. This directly affects Texas school districts by altering the property tax base used to determine state funding allocations. The bill clarifies that these exclusions must be applied when calculating the taxable value for school finance purposes, ensuring specific exemptions are not counted toward funding formulas. The change applies to school funding calculations for the 2025-2027 fiscal periods.
