Covered employers include, but are not limited to: the state of Iowa and its administrative agencies; counties, including their hospitals and county homes; cities, including their hospitals, park boards and commissions; recreation commissions; townships; public libraries; cemetery associations; municipal utilities including waterworks, gasworks, electric light and power; school districts including their lunch and activity programs; state colleges and universities; and state hospitals and institutions.
An entity not already reporting to IPERS which meets the conditions for becoming an IPERS-covered employer shall immediately contact IPERS to provide notice which includes the name and address of the entity and other information required by IPERS. If, after review of this information, IPERS determines that the entity should be enrolled as a covered employer, IPERS will notify the entity and provide an IPERS account number for the entity to use when submitting information. IPERS shall not be required to provide benefits otherwise available under Iowa Code chapter 97B for periods of service prior to the effective date for which IPERS actually approves the entity for coverage, unless the employer agrees to pay the full actuarial cost of providing such benefits.
An employer may request a revised beginning date for its status as a covered employer. The employer must submit acceptable proof to IPERS that its status as a covered employer began earlier than the date previously provided. In such case, the employer shall provide IPERS coverage retroactively to all employees providing services to that employer on or after the revised beginning date and shall pay all actuarial costs.
