The Illinois Municipal Retirement Fund (IMRF)

An IMRF pension offers life-long income protection. You earn service credit toward a Tier 1 Regular Plan IMRF pension by: Working for an IMRF employer in an IMRF-eligible position or contributing 4.5% of your salary toward your future pension. To begin receiving an IMRF Tier 1 Regular Plan pension, you must have at least eight years of service credit (can include reciprocal retirement system service credit), cannot be working in any position which qualifies for IMRF participation, and must be at least age 55. Although you can retire as early as age 55, age 60 is your full retirement age. Your pension may be reduced if you retire before age 60, depending upon the amount of service credit you have.
