(40 ILCS 5/7-173) (from Ch. 108 1/2, par. 7-173)
    Sec. 7-173. Contributions by employees.
    (a) Each participating employee shall make contributions to the fund as follows:
        1. For retirement annuity purposes, normal
    
contributions of 3 3/4% of earnings.
        2. Additional contributions of such percentages of
    
each payment of earnings, as shall be elected by the employee for retirement annuity purposes, but not in excess of 10%. The selected rate shall be applicable to all earnings paid following receipt by the Board of written notice of election to make such contributions. Additional contributions at the selected rate shall be made concurrently with normal contributions.
        3. Survivor contributions, by each participating
    
employee, of 3/4% of each payment of earnings.
    (b) (Blank).
    (c) Contributions shall be deducted from each corresponding payment of earnings paid to each employee and shall be remitted to the board by the participating municipality or participating instrumentality making such payment. The remittance, together with a report of the earnings and contributions shall be made as directed by the board. For township treasurers and employees of township treasurers qualifying as employees hereunder, the contributions herein required as deductions from salary shall be withheld by the school township trustees from funds available for the payment of the compensation of such treasurers and employees as provided in the School Code and remitted to the board.
    (d) An employee who has made additional contributions under paragraph (a)2 of this Section may upon retirement or at any time prior thereto, elect to withdraw the total of such additional contributions including interest credited thereon to the end of the preceding calendar year, to the extent permitted by the federal Internal Revenue Code of 1986, as now or hereafter amended.
    (e) Failure to make the deductions for employee contributions provided in paragraph (c) of this Section shall not relieve the employee from liability for such contributions. The amount of such liability may be deducted, with interest charged under Section 7-209, from any annuities or benefits payable hereunder to the employee or any other person receiving an annuity or benefit by reason of such employee's participation.
    (f) A participating employee who has at least 40 years of creditable service in the Fund may elect to cease making the contributions required under this Section. The status of the employee under this Article shall be unaffected by this election, except that the employee shall not receive any additional creditable service for the periods of employment following the election. An election under this subsection relieves the employer from making additional employer contributions in relation to that employee.
