Michigan’s teacher pension changes have moved the Public School Employees Retirement System away from a single guaranteed pension and toward a stack of hybrid and savings-based plans, with your hire date deciding which set of rules applies to you. What you contribute, how your pension is calculated, whether you get a cost-of-living adjustment, and what healthcare help you receive in retirement all depend on when you first landed on a public school payroll.1Michigan House Fiscal Agency.

Plan Tiers by Hire Date
Each round of reform created a new tier, and the tier follows you for your whole career. Find your hire date on this list and you know which rulebook governs your benefits.
- Hired before January 1, 1987: Basic Plan. A traditional defined benefit pension with no required employee contribution toward the pension itself.
- Hired between January 1, 1987, and June 30, 2010: Member Investment Plan (MIP). Sub-groups by exact start date change your contribution rate and some eligibility rules: MIP Fixed (January 1, 1987 through December 31, 1989), MIP Graded (January 1, 1990 through June 30, 2008), and MIP Plus (July 1, 2008 through June 30, 2010).2Michigan Office of Retirement Services. Michigan Office of Retirement Services – 6.01 History of the Retirement Benefit Plans
- Hired between July 1, 2010, and January 31, 2018: Pension Plus. A hybrid plan combining a smaller defined benefit pension with a defined contribution savings account.
- Hired on or after February 1, 2018: a choice between the Pension Plus 2 hybrid plan and a savings-only Defined Contribution (DC) plan.
The DC option is the sharpest break from tradition. Members who elect it, or land in it by default, permanently give up any pension component in exchange for a portable savings account with an employer match.
The 2024 Default Change for New Hires
Public Act 92 of 2017 created Pension Plus 2 and gave new hires 75 days to choose between it and the DC plan. From February 1, 2018 through July 1, 2024, anyone who did not make an active choice was placed in the DC plan by default, permanently forfeiting the pension component.3Michigan Legislature. House Fiscal Agency House Bill 5021 – Amend Retirement Plan Options for Newly Qualified MPSERS Participants Many new teachers ended up in that default without understanding what they had lost.
House Bill 5021, signed by Governor Whitmer as Public Act 250, changed the default. The Office of Retirement Services confirms the old DC-default rule applied only to employees hired between February 1, 2018, and July 1, 2024.2Michigan Office of Retirement Services. Michigan Office of Retirement Services – 6.01 History of the Retirement Benefit Plans If you were hired after July 1, 2024, the DC-only default no longer applies. Whatever your start date, if you are still inside your first 75 days, making an active election matters more than almost any other early-career financial decision.
How the 2013 Multiplier Cut Affects Your Pension
If you have a defined benefit pension, your monthly check is built from three inputs: Final Average Compensation (FAC), a pension multiplier, and years of credited service. FAC is the average of your highest consecutive earnings, over five years for Basic Plan members and three years for MIP members.4Michigan Office of Retirement Services. Your Final Average Compensation
The 2013 reforms cut the multiplier. For most MIP and Basic Plan members, the formula now splits at a single date:
- Service before February 1, 2013: 1.5% multiplier.
- Service on or after February 1, 2013: 1.25% multiplier.5Michigan Office of Retirement Services. Estimating Your Pension
Some MIP 7% and Basic 4% members who agreed to pay higher contributions kept the 1.5% multiplier for their whole career or up to 30 years of service.5Michigan Office of Retirement Services. Estimating Your Pension Everyone else gets a two-part calculation, which routinely surprises people running retirement projections. Every year of service after February 2013 is worth about a sixth less in pension terms than a pre-2013 year of the same salary.
Cost-of-Living Adjustments by Tier
MIP retirees receive a 3% annual increase, fixed and non-compounding. On a starting pension of $2,000 per month, that means an added $60 each year, not 3% of the prior year’s adjusted amount. Pension Plus and Pension Plus 2 members receive no cost-of-living adjustment at all.1Michigan House Fiscal Agency. Michigan Public School Employees Retirement System MPSERS Across a 25-year retirement the gap compounds into real money, which is why teachers in the newer tiers should treat personal savings as filling a hole the old plan filled automatically.
Healthcare: From Premium Subsidy to Personal Healthcare Fund
Retiree healthcare is a separate benefit from the pension, and its rules have shifted at least as much as the pension formula.
Premium Subsidy for Older Members
Teachers hired before the healthcare cutoff qualify for the premium subsidy, which covers a percentage of retiree health, dental, and vision premiums. For years, these members paid 3% of compensation toward funding that future benefit. As of October 1, 2025, active members with the premium subsidy no longer have that 3% deducted from their paychecks.6Michigan Office of Retirement Services. 3% Healthcare Contribution No Longer Required If you have been paying it, that money should now be staying in your check.
Personal Healthcare Fund for Newer Members
Members hired after the subsidy cutoff instead receive a Personal Healthcare Fund, a portable investment account held inside a 401(k) or 457 plan and used for healthcare expenses in retirement. For DC plan members with a PHF, the first 2% of voluntary contributions goes into the healthcare fund and is matched dollar for dollar by the employer.7Michigan Office of Retirement Services. 6.03.04 Defined Contribution DC Plan and Basic Plan MIP Converted to DC Plan The balance stays with you if you leave public school work. The trade-off is that investment risk and adequacy risk sit on you rather than on the state.
Vesting and What You Lose If You Leave Early
Vesting decides whether you ever collect a pension check. The defined benefit pension requires 10 years of credited service.1Michigan House Fiscal Agency. Michigan Public School Employees Retirement System MPSERS A year of credited service generally means working at least 1,020 hours in the school fiscal year, which runs July 1 through June 30, with part-time employees earning proportional credit.8Michigan Office of Retirement Services. 5.01 How Service Credit Is Earned or Gained Reaching 10 years of credited service can take longer than 10 calendar years.
Leave before you vest and you forfeit the pension entirely. You can request a refund of your own contributions, but the employer-funded pension promise goes with you out the door. That is the single biggest trap for teachers who exit Michigan public schools after seven or eight years.
The DC side works differently. Your voluntary contributions are 100% yours from day one, and employer contributions vest on a graduated schedule over several years. Teachers uncertain whether they will stay long enough to hit 10 years may find the DC match more valuable than a pension they never vest into.
Return-to-Work Rules Through 2028
Retirees returning to public schools as substitutes, part-time staff, or consultants have to navigate a specific set of rules, and stepping outside them suspends the pension.
The starting requirement is a bona fide termination: a complete break in the employment relationship, no work at any public school or for the State of Michigan during the month of your retirement effective date, and no prearranged rehire agreement.9Michigan Office of Retirement Services. Working After You Retire After that clean break, two paths preserve your pension:
- Return immediately but earn no more than $15,100 in a calendar year from public school employment.
- Wait at least six consecutive months after retirement, then return with no earnings cap.9Michigan Office of Retirement Services. Working After You Retire
Violate either rule and your pension and insurance premium subsidy are temporarily forfeited. Benefits resume the month after you become eligible again, but ORS does not recalculate to recover the missed payments, and your six-month clock restarts. These return-to-work provisions are in effect until October 10, 2028, and may change after that date.9Michigan Office of Retirement Services. Working After You Retire
Why More Changes May Come
The recent tiers, the multiplier cut, the DC-default period, and the ongoing debate over hybrid plans all trace back to a funding problem. The most recent actuarial valuation put the MPSERS unfunded liability at roughly $35.1 billion, with a funded ratio of about 64.3%. The state has responded with a $1 billion one-time deposit and an accelerated shift to level-dollar amortization expected in fiscal year 2025-26.1Michigan House Fiscal Agency. Michigan Public School Employees Retirement System MPSERS
Those steps reduce long-term costs, and they also explain the political pressure that produced every reform to date. For teachers years or decades from retirement, the funding trajectory is worth watching. It shapes whether the next legislature holds the current structure stable or reaches for another round of changes.
