Adding to Your Service Credit

The longer you work as a member in the Defined Benefit (DB) Plan, the higher your pension will be.

But there are other ways to increase the years of service (YOS) in your pension calculation. Service credit for certain other types of employment may be granted or transferred; service credit may be purchased; and service credit may be restored if you withdrew your DB pension contributions to the retirement system after a previous period of employment and want to repay the full amount withdrawn, with interest. 

General rules for service credit purchases.

Each type of service credit has specific rules, costs, and applications. Before you dig into the details though, read the following tips so you're ready to make what can be a complicated and costly decision. 

• You must be an active member in the DB Plan. A service credit purchase or repayment of previously refunded contributions must be completed while you're an active member — that is, while you're still employed by a participating public school. The purchase must be completed before you terminate employment from a Michigan public school reporting unit. A service credit purchase can never be initiated after you've stopped working within the retirement system or after switching to the Defined Contribution Plan. 
• You'll need to establish a wage base. You must earn at least 2 YOS before you're eligible to make a purchase, and some time must be earned in the immediately preceding fiscal year. 
• Purchased service credit and insurance subsidies. 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. If you're planning on enrolling in insurances when you retire, be sure you understand whether you'll be subject to a delayed subsidy. 
• No double-dipping. When you get credit for other service, whether granted or purchased, you typically have to give up your rights to any benefit that would have been payable under the other pension system. 
• You can't buy your way in. Unless you plan to retire under one of the age 60 eligibility provisions, you'll need to earn at least 15 YOS in this retirement system (State of Michigan service under the DB Plan transferred before Sept. 29, 2017, is treated as earned in this retirement system). Non-intervening military service credit has a maximum purchase limit and won't count in your pension calculation until you have earned 10 years working within this retirement system. 
• You must be vested for your purchase to count. Unless otherwise noted, most purchases won't count in your service total until you're vested. You're vested when you have sufficient service to qualify for a future monthly benefit, whether you continue working for a public school. Most school employees are vested after the full-time equivalent of 10 years. 
• With few exceptions, purchased service credit can't count toward your vesting requirement.

Your purchases are part of your DB pension contributions. 

Your payments for service credit are put into a separate account along with any of your contributions from earnings before July 1, 1977. This account is separate from your MIP or Basic 4% contributions. Interest is credited annually on your pension contributions that have been on deposit for a full school fiscal year. Learn more about your contribution account. 

If you leave public school employment before you've reached the minimum age and service requirement for a pension, you can request a refund of your pension contributions. However, you would forfeit all service and insurance subsidy eligibility those contributions represent, so it's generally not a good idea if you're vested. Your public school employment must be terminated for at least six months before you can apply for a refund in miAccount. If your public school employment has been terminated for less than six months, you must complete a paper Refund Application (R0311C). A paper application is required because your school district must certify you've ended all employment with the reporting unit before we can issue a refund. There is no provision for a partial refund, nor can you borrow against your pension contributions. If you die before reaching retirement eligibility, your pension contributions will be paid to your beneficiary or estate. While you're an active public school employee, use the Beneficiary Nomination (R0315C) form to let ORS know who should receive your pension contributions (or, if vested, a monthly survivor pension).

Weigh your cost versus benefit. 

"Buying time" isn't always an easy decision. You have to weigh the costs, with the benefits. Fortunately, there's a tool to help you decide the benefits: our pension estimate calculator. You can enter any number of "what-if" scenarios, and the program will quickly give you a pension estimate.
