The Pension Code provides for service credit for qualifying employment before the employer (unit of government) joined IMRF. This type of service credit is called prior service credit.
Unit of government joined IMRF on or before January, 1, 1998
Members who rendered service in an IMRF covered position prior to the date their governmental unit entered IMRF may receive all of their prior service credit at no cost to the member .
Unit of government joined IMRF after January, 1, 1998
Members who rendered service in an IMRF covered position prior to the date their governmental unit entered IMRF may receive five years of their prior service credit or 20 percent of their total prior service, whichever is less, at no cost to the member.
The member can purchase any remaining prior service by paying the member contributions , plus interest. A member’s eligibility to purchase the remaining years of service is not discretionary with the unit of government. The salary used to calculate the cost to purchase the prior service is the salary as of the date the unit of government joined IMRF.
The member may be eligible to use funds from a traditional Individual Retirement Account (IRA ) or from another qualified plan or 457 or 403(b) plan to purchase the prior service credit. (See 6.40 C. Member Application and Payments.)
Regardless of when the unit of government joined IMRF, a member would apply for prior service by submitting IMRF Form entitled, "Application for Prior Service Credit" under the following conditions:
The member must be employed in a covered position on the date the governmental unit enters IMRF, or
The governmental unit entered IMRF but has now returned to work for that governmental unit and has completed two years of contributing service after re-entry.
There is no immediate payment required of the employer. The cost to the governmental unit is reflected in its future employer contribution rates.
