Sec. 46. (1) Except as otherwise provided in this section, a retirement allowance, an optional benefit, or any other benefit accrued or accruing to a person under this act, the reserves created by this act, and the money, investments, or income of those reserves are exempt from state, county, municipal, or other local tax and are subject to the public employee retirement benefit protection act, 2002 PA 100, MCL 38.1681 to 38.1689.

(2) Beginning January 1, 2012, a retirement allowance, an optional benefit, or any other benefit accrued or accruing to a person under this act is subject to state tax upon distribution to the person from the various funds created by this act.

(4) If the retirement system is required by the federal government pursuant to a court order to transmit a part of a member's contributions standing to the member's credit in the reserve for employee contributions to a federal agency, the service credit that is covered by the payment shall be forfeited in the same manner as if the employee had requested and been paid a refund of the member's most recent contributions.
