Illinois Statutes Chapter 40. Pensions § 5/2-126. Contributions by participants

(a) Each participant shall contribute toward the cost of his or her retirement annuity a percentage of each payment of salary received by him or her for service as a member as follows: for service between October 31, 1947 and January 1, 1959, 5%; for service between January 1, 1959 and June 30, 1969, 6%; for service between July 1, 1969 and January 10, 1973, 6 1/2%; for service after January 10, 1973, 7%; for service after December 31, 1981, 8 1/2%.

(b) Beginning August 2, 1949, each male participant, and from July 1, 1971, each female participant shall contribute towards the cost of the survivor's annuity 2% of salary.

A participant who has no eligible survivor's annuity beneficiary may elect to cease making contributions for survivor's annuity under this subsection. A survivor's annuity shall not be payable upon the death of a person who has made this election, unless prior to that death the election has been revoked and the amount of the contributions that would have been paid under this subsection in the absence of the election is paid to the System, together with interest at the rate of 4% per year from the date the contributions would have been made to the date of payment.

(c) Beginning July 1, 1967 and, in the case of Tier 1 participants, ending on June 30, 2014, each participant shall contribute 1% of salary towards the cost of automatic increase in annuity provided in Section 2-119.1. These contributions shall be made concurrently with contributions for retirement annuity purposes.

(d) In addition, each participant serving as an officer of the General Assembly shall contribute, for the same purposes and at the same rates as are required of a regular participant, on each additional payment received as an officer. If the participant serves as an officer for at least 2 but less than 4 years, he or she shall contribute an amount equal to the amount that would have been contributed had the participant served as an officer for 4 years. Persons who serve as officers in the 87th General Assembly but cannot receive the additional payment to officers because of the ban on increases in salary during their terms may nonetheless make contributions based on those additional payments for the purpose of having the additional payments included in their highest salary for annuity purposes; however, persons electing to make these additional contributions must also pay an amount representing the corresponding employer contributions, as calculated by the System.

(e) Notwithstanding any other provision of this Article, the required contribution of a participant who first becomes a participant on or after January 1, 2011 shall not exceed the contribution that would be due under this Article if that participant's highest salary for annuity purposes were $106,800, plus any increases in that amount under Section 2-108.1.
