To lawfully employ a PERS service retiree under Section 103, the employer must notify PERS in writing of the terms of the eligible employment within five days from the date of employment and also from the date of termination on a form prescribed by the Board. Failure by the employer to timely notify PERS may result in the assessment of a $300 penalty per occurrence payable by the employer.
A service retiree reemployed under Section 103 may make one election per fiscal year to either (i) limit the number of days/ hours worked for all covered employers to that allowed under
Section 103.1.a. or (ii) limit the amount of compensation that will be earned from all covered employers as provided under Section 103.1.b. of this regulation.
A retiree who continues in or is elected to covered municipal or county office (and who is not also reemployed in a non-elective position) may make one election per fiscal year to either (i) waive his or her salary and continue to receive a retirement allowance under Section 103.2.a. or (ii) elect to receive an amount not to exceed 25 percent of the retiree's average compensation in Section 103.2.b. Note that such elected official does not have the option of limiting the number of days or hours worked.
