Types of Service Credit

There are different types of service credit, each with 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.

It is not uncommon for members to have a number of service credit purchases or transfer options. If this is your situation, ask an ORS customer service representative to explain the ramifications of each so that you can make an informed choice that best meets your needs.

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".
