Sec. 8. MEMBER CONTRIBUTIONS. (a) Subject to adjustments authorized under Section 8E or 8F of this Act, beginning on the year 2017 effective date, each member of the pension system shall make biweekly contributions during employment in an amount determined in accordance with this section. The contributions shall be deducted by the employer from the salary of each member and paid to the pension system for deposit in the pension fund. Member contributions under this section shall be made as follows:

(1) each group A member shall contribute:

(A) seven percent of the member's salary beginning with the member's first full biweekly pay period that occurs on or after the year 2017 effective date; and

(B) a total of eight percent of the member's salary beginning with the member's first full biweekly pay period for the member that occurs on or after July 1, 2018;

(2) each group B member shall contribute:

(A) two percent of the member's salary beginning with the member's first full biweekly pay period that occurs on or after the year 2017 effective date; and

(B) a total of four percent of the member's salary beginning with the member's first full biweekly pay period for the member that occurs on or after July 1, 2018; and

(3) each group D member shall contribute two percent of the member's salary beginning with the member's first full biweekly pay period that occurs on or after the year 2017 effective date.

(b) This section does not increase or decrease the contribution obligation of any member that arose before the year 2017 effective date or give rise to any claim for a refund for any contributions made before that date.

(c) The employer shall pick up the contributions required of members by Subsection (a) of this section and contributions required of group D members under Section 10A(a) of this Act as soon as reasonably practicable under applicable rules for all salaries earned by members after the year 2017 effective date and by January 1, 2018, for contributions required by Section 10A(a) of this Act. The city shall pay the pickup contributions to the pension system from the same source of funds that is used for paying salaries to the members. The pickup contributions are in lieu of contributions by members. The city may pick up those contributions by a deduction from each member's salary equal to the amount of the member's contributions picked up by the city. Members may not choose to receive the contributed amounts directly instead of having the contributed amounts paid by the city to the pension system. An accounting of member contributions picked up by the employer shall be maintained, and the contributions shall be treated for all other purposes as if the amount were a part of the member's salary and had been deducted under this section. Contributions picked up under this subsection shall be treated as employer contributions in determining tax treatment of the amounts under the Internal Revenue Code of 1986, as amended.

(d) Repealed by Acts 2017, 85th Leg., R.S., Ch. 320 (S.B. 2190), Sec. 3.24, eff. July 1, 2017.
