§ 14-104 — Service for which contributions permitted

Contributions provided for in this Section shall cover the period of service granted. Except as otherwise provided in this Section, the contributions shall be based upon the employee's compensation and contribution rate in effect on the date he last became a member of the System; provided that for all employment prior to January 1, 1969 the contribution rate shall be that in effect for a noncovered employee on the date he last became a member of the System. Except as otherwise provided in this Section, contributions permitted under this Section shall include regular interest from the date an employee last became a member of the System to the date of payment. These contributions must be paid in full before retirement either in a lump sum or in installment payments in accordance with such rules as may be adopted by the board. (a) Any member may make contributions as required in this Section for any period of service, subsequent to the date of establishment, but prior to the date of membership.

(d) Any employee who rendered service in a State office to which he was elected, or rendered service in the elective office of Clerk of the Appellate Court prior to the date he became a member, may make contributions for such service as required in this Section.

(f) An employee of the Department of Labor of the State of Illinois who performed services for and under the supervision of that Department prior to January 1, 1944 but who was compensated for those services directly by federal funds and not by a warrant of the Auditor of Public Accounts paid by the State Treasurer may establish credit for such employment by making the contributions required in this Section. An employee of the Department of Agriculture of the State of Illinois, who performed services for and under the supervision of that Department prior to June 1, 1963, but was compensated for those services directly by federal funds and not paid by a warrant of the Auditor of Public Accounts paid by the State Treasurer, and who did not contribute to any other public employee retirement system for such service, may establish credit for such employment by making the contributions required in this Section. (g) Any employee who executed a waiver of membership within 60 days prior to January 1, 1944 may, at any time while in the service of a department, file with the board a rescission of such waiver. Upon making the contributions required by this Section, the member shall be granted the creditable service that would have been received if the waiver had not been executed.

A member may establish service credit under this subsection for more than one period of authorized leave, and in that case the total period of service credit established by the member under this subsection may exceed one year. In determining the contributions required for establishing service credit under this subsection, the interest shall be calculated from the beginning of the leave of absence to the date of payment.

This subsection (p) applies without regard to whether the person was in service on or after the effective date of this amendatory Act of the 94th General Assembly.
