Social Security Integration is a pension benefit payment option available to PERF and TRF members at retirement. If you retire between ages 50 and less than age 62, you may combine the PERF or TRF monthly pension benefit with your estimated Social Security benefits. INPRS pays a larger monthly benefit before age 62. The payment may be greatly reduced or terminated at age 62. Your estimated monthly Social Security payment determines if your INPRS payment will be reduced or terminated. INPRS does not work in conjunction with Social Security. This selection will not impact the benefit received from Social Security.
