Relating to the dedication of certain state money for ad valorem tax relief.

SB 403 requires Texas to deposit federal reimbursements for border security costs into a dedicated account within the general revenue fund. The comptroller must calculate this amount annually and deposit it by the 90th day of each fiscal year. This money can only be used by the legislature to provide property tax relief (ad valorem tax relief) for homeowners and businesses. The bill takes effect September 1, 2025, but applies to fiscal years beginning September 1, 2027. It directly affects Texas taxpayers through potential property tax reductions, using existing federal border security reimbursements rather than new state funds.
