Relating to retirees of the Teacher Retirement System of Texas who resume certain employment with a school district.

HB 1166 modifies Texas law to change when school districts must pay certain amounts to the Teacher Retirement System for retirees who return to work. It exempts school districts from these payments for retirees who retired before September 1, 2005, or for those who retired on or after that date if they qualify for an exception under existing retirement rules and the district proves it cannot fill the position without a temporary hire. The bill directly affects school districts' payroll obligations for certain returning retirees. The changes apply to all retirees regardless of retirement date and take effect for the 2025-2026 school year.
