Who participates in which tier of benefits?

IMRF members who first participated in IMRF or a reciprocal system before January 1, 2011, will always be enrolled in Tier 1*. The Illinois General Assembly created a second tier for the IMRF Regular and Elected County Official plans for new participants enrolled on or after January 1, 2011.

IMRF members who first participate in IMRF or a reciprocal system on or after January 1, 2011, will participate in Tier 2.

When you enroll a new member in IMRF, we will automatically determine the member's plan and tier and display it in employer access. Remember, when a new member is enrolled, IMRF sends a "New Member Packet" to the member, which includes a benefit booklet for their plan and tier, a letter explaining which tier they participate in, and other information about IMRF.

*With the exception of previous participants of the Judges or General Assembly Retirement Systems, who would participate in Tier 2 if the first IMRF participation date is on or after January 1, 2011.
