HB 1623 seeks to amend the eligibility criteria under the Texas Jobs, Energy, Technology, and Innovation Act for entities or individuals applying for a limitation on the taxable value of property for school district maintenance and operations ad valorem tax purposes. The bill explicitly excludes certain foreign entities or individuals associated with "designated countries" identified as national security risks by the U.S. intelligence community. It imposes stricter requirements for the approval and termination of agreements related to these property value limitations, including expanded reporting by the comptroller and increased oversight by the attorney general.
