The members' contributions picked up by the State shall be designated for all purposes of the Retirement System as member contributions, except for the determination of tax upon a distribution from the System. These contributions shall be credited to the annuity savings fund and accumulated within the fund in a member's account which shall be separately established for the purpose of accounting for picked-up contributions.
Member contributions picked up by the State shall be payable from the same source of funds used for the payment of compensation to a member. A deduction shall be made from a member's compensation equal to the amount of his contributions picked up by the State. This deduction, however, shall not reduce a member's compensation as defined in subdivision (5) of G.S. 135-53. Picked up contributions shall be transmitted to the Retirement System monthly for the preceding month by means of a warrant drawn by the State payable to the Retirement System and shall be accompanied by a schedule of the picked-up contributions on such forms as may be prescribed.
