(c) Pickup of employee contributions. The Employer may pick up employee contributions required under subsections (a) and (b) of this Section. If contributions are picked up they shall be treated as Employer contributions in determining tax treatment under the United States Internal Revenue Code, and shall not be included as gross income of the employee until such time as they are distributed. The Employer shall pay these employee contributions from the same source of funds used in paying salary to the employee. The Employer may pick up these contributions by a reduction in the cash salary of the employee or by an offset against a future salary increase or by a combination of a reduction in salary and offset against a future salary increase. If employee contributions are picked up they shall be treated for all purposes of this Article 13, including Sections 13-503 and 13-601, in the same manner and to the same extent as employee contributions made prior to the date picked up.

(d) Subject to the requirements of federal law, the Employer shall pick up optional contributions that the employee has elected to pay to the Fund under Section 13-304.1, and the contributions so picked up shall be treated as employer contributions for the purposes of determining federal tax treatment. The Employer shall pick up the contributions by a reduction in the cash salary of the employee and shall pay the contributions from the same fund that is used to pay earnings to the employee. The Employer shall, however, continue to withhold federal and State income taxes based upon contributions made under Section 13-304.1 until the Internal Revenue Service or the federal courts rule that pursuant to Section 414(h) of the U.S. Internal Revenue Code of 1986, as amended, these contributions shall not be included as gross income of the employee until such time as they are distributed or made available.

(e) Each employee is deemed to consent and agree to the deductions from compensation provided for in this Article.

(f) Subject to the requirements of federal law, the Employer shall pick up contributions that a commissioner has elected to pay to the Fund under Section 13-314, and the contributions so picked up shall be treated as Employer contributions for the purposes of determining federal tax treatment. The Employer shall pick up the contributions by a reduction in the cash salary of the commissioner and shall pay the contributions from the same fund as is used to pay earnings to the commissioner. The Employer shall, however, continue to withhold federal and State income taxes based upon contributions made under Section 13-314 until the U.S. Internal Revenue Service or the federal courts rule that pursuant to Section 414(h) of the Internal Revenue Code of 1986, as amended, these contributions shall not be included as gross income of the employee until such time as they are distributed or made available.
