No, the Teacher Retirement System does not allow this. Other considerations may be your 403(b) TDA or your Texa$aver (457) Plan if you are enrolled in either of those plans. Contact your TDA vendor representative for options. Contact information is on the Human Resources website at http://www.hr.txstate.edu/benefits/Retirement-Programs-and-Information-/orpvendors.html. You can contact a representative of the Texa$aver Plan at 800-634-5091.
You can retire with State paid retiree insurance when your age plus years of service equals 80 or when you reach age 65 with 10 years of service. Your years of service must include at least 10 years of service in a benefits eligible position with a GBP participating agency. If you retire before age 65 with 10 years of service, you can elect interim retiree insurance at your own expense until you reach age 65. Then at age 65 you can enroll in the state paid retiree insurance plan. If you retire before age 65 with less than 10 years of service, you will never be able to enroll in the retiree insurance.
Teacher Retirement System staff ask that you contact them 4 - 6 months ahead of time, if possible. If you qualify for retiree insurance, you should come to Human Resources at least one month before your retirement date to enroll in the insurance. A Retiree Checklist is located here.
When you retire and have Medicare at age 65, Medicare is primary. If you come back to work in a benefits-eligible position (at least 50% time), your health plan through Texas State becomes primary while you are working.
