Michigan Teacher Retirement: A Complete MPSERS Overview

How MPSERS Works

The Michigan Public School Employees' Retirement System covers teachers, administrators, and support staff across K-12 districts, intermediate school districts, charter schools, community colleges, and certain state universities. It's administered by the Office of Retirement Services (ORS) under the Public School Employees Retirement Act (MCL 38.1301 et seq.).

MPSERS isn't one plan — it's five, determined by when you were first hired and which elections you made under the 2012 reform.

The Five Plan Tiers

Basic Plan (hired before January 1, 1990, without electing MIP): Non-contributory defined benefit with a 60-month FAC window. Unreduced retirement at age 55 with 30 years of service, or age 60 with 10 years. No automatic post-retirement increase.

Member Investment Plan (MIP) (hired January 1, 1990 – June 30, 2010): Contributory defined benefit with a 36-month FAC window. Unreduced retirement at age 46 with 30 years of service, or age 60 with 10 years. Includes an automatic 3% annual post-retirement increase on the initial pension amount after any early-reduced or survivor-option adjustment.

Pension Plus (hired July 1, 2010 – January 31, 2018): Hybrid — a 1.5% DB pension plus a mandatory Voya-administered DC account. Age 60 with 10 years of earned service.

Pension Plus 2 (hired February 1, 2018 or later): Similar hybrid structure with mandatory 50/50 employer/employee cost-sharing on the DB pension. Age 60 with 10 years.

Defined Contribution only (PA 300 opt-outs or DC electors): No monthly pension from MPSERS — retirement income comes from a Voya 401(k) with employer contributions and matching, plus any separate voluntary 457 savings.

The Pension Formula

For all DB tiers, the monthly pension formula is:

Final Average Compensation × Years of Service × 1.5% ÷ 12

FAC is calculated over your highest consecutive 36 months (MIP, Pension Plus, Pension Plus 2) or 60 months (Basic Plan). Some members who elected the lower multiplier under PA 300 of 2012 have a blended rate of 1.5% for service before February 1, 2013, and 1.25% for service on or after that date.

A teacher with a $68,000 FAC and 28 years of service at the full 1.5% multiplier receives: $68,000 × 28 × 0.015 = $28,560 per year, or $2,380 per month before taxes and deductions.

Healthcare After Retirement

Your retiree health coverage depends on your hire date:

Members hired before 2010 generally qualify for the Premium Subsidy — ORS pays a percentage of your health insurance premium, reaching the maximum subsidy at 25 years of service. The subsidy scales with years of service for those with fewer than 25 years (the "graded" subsidy).

Members hired after July 1, 2010, typically have the Personal Healthcare Fund (PHF) — a 2% employer match into your DC savings account earmarked for healthcare. No premium subsidy. At retirement, you either pay 100% of the MPSERS health plan premium yourself or arrange your own coverage.

Starting October 1, 2025, the mandatory 3% active employee healthcare contribution is eliminated under Public Act 127 of 2024. This doesn't change your retiree benefit structure — it just stops the payroll deduction.

Recent Law Changes That Affect Your Retirement

Public Act 4 of 2023 phases in Michigan retirement-income deductions. For tax year 2026, all birth-year cohorts may claim the full applicable deduction; for most filers, the limit is $67,610 single or $135,220 joint. Retirement income above the applicable limit may remain taxable. Taxpayers born before 1946 retain the prior unlimited subtraction for public-source benefits.

Public Act 147 of 2023 sets return-to-work rules through October 10, 2028: after a bona fide termination, a retiree who returns to a public school job must either complete a six-month break in service (no earnings limit) or stay under $15,100 per calendar year. Exceeding the limit suspends pension payments and health subsidies for the rest of that calendar year.

The Social Security Fairness Act (signed January 2025) repealed the WEP and GPO retroactive to January 2024. Michigan teachers pay Social Security taxes, so WEP rarely affected standard MPSERS pensions — but the repeal matters if you or your spouse had non-covered employment in another state.

Where to Start

Your retirement planning should begin 12 to 18 months before your target date. The sequence: audit your service credit in miAccount, run pension estimates under multiple scenarios, gather required documents (proofs of age and marriage, DD-214 if applicable), and submit your application through miAccount during the three-month window before your retirement effective date.

For a step-by-step walkthrough of the entire process — from reading your pension estimate to selecting your payout option to enrolling in health coverage — the MPSERS Retirement Guide covers every plan tier with worked examples and a countdown checklist.
