SB 510 requires all new state legislators, judges, county officials, and district attorneys general taking office on or after July 1, 2025, to join Tennessee’s public retirement system (TCRS) as a condition of taking office. It also mandates that part-time state employees hired on or after July 1, 2025, become TCRS members unless excluded by specific categories (e.g., students, seasonal workers). The bill allows retirees to update their beneficiary designations to a new spouse following a divorce that cancels a former spouse’s benefit. Effective May 5, 2025, the law amends multiple retirement chapters (Titles 8, Chapters 25, 34-37) to implement these changes.
