(1) A disability beneficiary restored to active service at a salary less than his average final compensation shall not become a member of the System and his retirement allowance shall be adjusted in accordance with the provisions of § 9-11-80(4).

(2) Should a disability beneficiary under the age of fifty-five years be restored to active service and his compensation then, or at any time thereafter, be equal to or greater than his average final compensation at retirement, his retirement allowance shall cease, any election of an optional benefit shall become void, and he shall again become a member of the System and contribute thereafter as provided in § 9-11-210(1). Any credited service to which he was entitled when he retired shall be restored to him, and upon subsequent retirement his allowance shall be based on his compensation and credited service before and after the period of prior retirement. The average final compensation in subsections (1) and (2) of this section may be increased up to ten percent annually to adjust for inflation.

(3) Should any other beneficiary who has been restored to active employment continue in service for a period of forty-eight consecutive months and his annual compensation be equal to or greater than seventy-five percent of his average final compensation at retirement, then he may elect to cease his retirement allowance and become a contributing member again and void his election of an optional benefit. Any credited service to which he was entitled when he retired must be restored to him, and upon subsequent retirement his allowance must be based on his compensation and credited service before and after the period of prior retirement. Any such beneficiary may request the Board to allow him to repay to the System all monies received by him as benefits during any periods subsequent to the date of his reentry into active service and make a contribution equal to the amount he would have contributed had he been a member during the period of his restoration to active service prior to his again becoming a member, together with the interest which would have been credited to the contributions on account of the period of restoration up to the date the contribution is made. Upon the completion of the payment, this period must also be credited to him as membership service. In no event must the retirement allowance payable upon subsequent retirement be less than the amount of his allowance previously payable plus any increases which would have been payable under § 9-11-310 had he not been restored to service.

(4)(a)(i) Notwithstanding the provisions of subsections (1) and (2) of this section, a retired member of the system who has been retired for at least thirty consecutive calendar days may be hired and return to employment covered by this system or any system provided in this title and may earn up to ten thousand dollars without affecting the monthly retirement allowance the member is receiving from this system. If the retired member continues in service after having earned ten thousand dollars in a calendar year, the member’s retirement allowance must be discontinued during the member’s period of service in the remainder of the calendar year. If the employment continues for at least forty-eight consecutive months, the provisions of § 9-11-90(3) apply. If a retired member of the system returns to employment covered by the South Carolina Police Officers Retirement System or any other system provided in this title sooner than thirty consecutive calendar days after retirement, the member’s retirement allowance is suspended while the member remains employed by a participating employer of any of these systems. If an employer fails to notify the system of the engagement of a retired member to perform services, the employer shall reimburse the system for all benefits wrongly paid to the retired member.

(ii) The earnings limitation imposed pursuant to this item does not apply if the member meets at least one of the following qualifications:

(A) the member retired before January 2, 2013;

(B) the member has attained the age of fifty-seven years at retirement; or

(C) compensation received by the retired member from the covered employer is for service in a public office filled by the appointment of the Governor and with confirmation by the Senate, by appointment or election by the General Assembly, or by election of the qualified electors of the applicable jurisdiction.

(b) An employer shall pay to the system the employer contribution for active members prescribed by law with respect to any retired member engaged to perform services for the employer, regardless of whether the retired member is a full-time or part-time employee or a temporary or permanent employee. If an employer who is obligated to the system pursuant to this subsection fails to pay the amount due, as determined by the system, the amount must be deducted from any funds payable to the employer by the State.

(c) A retired member shall pay to the system the employee contribution as if the member were an active contributing member if an employer participating in the system employs the retired member. The retired member does not accrue additional service credit in the system by reason of the contributions required pursuant to this item and item (b) of this subsection.

(d) A retired member of the Police Officers Retirement System who is not a member of the South Carolina Retirement System, but is employed in a position that would otherwise be covered by the South Carolina Retirement System, shall not join the South Carolina Retirement System but, notwithstanding any other provision of law, that member is deemed a retired contributing member of the Police Officers Retirement System and shall remit the employee contributions required under item (c) of this subsection to the Police Officers Retirement System and the employer shall remit to the Police Officers Retirement System the employer contribution required by item (b). An employer who hires a retiree of the Police Officers Retirement System pursuant to this subsection shall elect to participate as an employer in the Police Officers Retirement System.

(5) Notwithstanding the provisions of subsection (3), a retired member who has been restored to active employment by virtue of election to the office of sheriff is restored as a member of the system upon taking office and electing to cease receiving a retirement allowance. Credited service to which the sheriff was entitled when he retired is restored to the sheriff and upon subsequent retirement the allowance must be based on the sheriff’s compensation and credited service before and after the period of prior retirement. The allowance must not be less than the amount of his allowance previously payable plus any increases which would have been payable under § 9-11-310 had he not been restored to service.
