The Teacher Retirement System (TRS) Rates tab is used to maintain the TRS assigned rate that is used to calculate district TRS fees and contributions to the retirees' health insurance program. The TRS rate information must be the most current for the fee and contribution calculations to be accurate. The TRS rate information can be updated at any time and is available through the TRS Payroll Reporting Procedures Manual (go to the TRS Web site at www.trs.state.tx.us, and select Reporting Officials to obtain a copy of this document).
