Types of Service Credit

Public Act 92 of 2017, which was signed into law on July 13, discontinued the option to purchase most types of service credit as of September 29, 2017. However, active members of the Michigan Public School Retirement System may still purchase Active Duty Military Service and make payments to reinstate service canceled by a refund or to make whole member contributions that should have been made, but weren’t. These service credit types have specific rules, costs, and applications. In this section, we list the various types of service credit that you may be able to purchase or transfer. We also provide a summary chart below.

Important Information

Buying service can help you qualify for your pension earlier, but it won't necessarily help you qualify for the plan's health insurance premium subsidy earlier. For more information refer to the Delayed Subsidy Examples.

A note about costs.

The cost for your service credit may be based on a flat percentage rate, an actuarial rate, or a combination of contributions and interest. Where possible, we give you details and examples so you can estimate your cost. You can always get an actual cost by sending ORS an application or by requesting a "bill".
