The municipal employees' retirement system of michigan — known as MERS — is one of the largest public pension systems in the state, serving local governments since 1945. Yet many municipal workers reach retirement age knowing surprisingly little about how their plan actually works. That gap creates real problems: missed benefit options, poor timing decisions, and confusion during enrollment windows.
In this guide, you'll learn five essential facts about MERS, including how its plan types differ, what happens when you change employers, and how to access your account. You'll also get practical steps you can take today to protect your future pension.
Fact 1: MERS Has Served Michigan's Local Governments Since 1945
MERS is a multi-employer public retirement system headquartered in Michigan that provides pension and retirement services to municipalities, counties, and other local government units. The municipal employees' retirement system of michigan pools administration across hundreds of participating employers, so individual cities and townships avoid building their own pension infrastructure from scratch.
This shared model matters for you as an employee. A common scenario: a police officer moves from one participating city to another within Michigan. Rather than losing credit, service records transfer through the system, preserving years of vesting progress.
The system is governed by a board of trustees and is subject to annual independent audits, with financial reports available to participating employers and members.
How to apply this: If you work for a Michigan municipality, ask your HR department whether your employer participates in MERS — eligibility is not automatic across all local government jobs.
Fact 2: MERS Offers Multiple Plan Types — Not Just One
A frequent misconception is that MERS is a single defined benefit (DB) pension. In reality, the municipal employees' retirement system of michigan allows participating employers to offer several structures, and the plan you have depends on your employer's contract with the system.
The main plan types include:
- Defined Benefit (DB): A traditional pension paying a lifetime benefit based on service years and salary
- Defined Contribution (DC): An account-based plan funded by employee and employer contributions
- Hybrid plans: A combination offering both a smaller DB pension and a DC savings account
Your plan type determines your risk, your benefit formula, and your options at separation. The comparison below shows how they differ at a glance.
| Plan type | How the benefit works | Key risk factor | Action to take |
|---|---|---|---|
| Defined Benefit | Lifetime pension from a formula | Employer funding status | Request your annual benefit statement |
| Defined Contribution | Value of your investment account | Market performance | Review your fund allocation yearly |
| Hybrid | DB pension plus DC account | Split across both | Track both components separately |
How to apply this: Request a copy of your employer's MERS plan document so you know exactly which plan type covers you.
Fact 3: Your Benefit Depends on Vesting, Service Credit, and Final Compensation
Under a MERS defined benefit plan, your pension generally reflects three variables: how long you worked (service credit), whether you vested, and the salary figure your benefit formula uses. Vesting rules determine the minimum service required before you earn a right to a pension.
The municipal employees' retirement system of michigan calculates each of these factors according to your employer's specific plan provisions.
Here's why this matters in practice. A maintenance worker with ten years of service who leaves municipal employment before reaching retirement eligibility may still hold a deferred pension — but only if vesting requirements were met. Failing to confirm this is one of the most common and costly mistakes retirees make.
Periods of leave, part-time work, or military service can also affect how service credit is calculated, sometimes requiring documentation to count them fully.
How to apply this: Log into your account and verify your recorded service hours match your employment history — errors compound over a career.
Fact 4: You Can Manage Your Account Online Through MERS Member Direct
MERS provides members with online access to their retirement records, which dramatically simplifies planning. Through the member portal of the municipal employees' retirement system of michigan, you can review your accrued benefit, update beneficiary information, and access plan documents without calling an administrator.
This matters because beneficiary designations are one of the most frequently overlooked items. If you married, divorced, or experienced a family change, an outdated designation can send your benefit to the wrong person regardless of your will.
The system also distributes an annual statement to members, and MERS recommends reviewing it each year. As MERS explains on its official website, members should contact the system directly with questions about their specific plan provisions, since benefits vary by employer contract (MERS of Michigan).
How to apply this: Create or refresh your member portal login this week and confirm your beneficiary information is current.
Fact 5: Tax Rules Apply to Your MERS Pension at Retirement
Pension income from MERS is subject to tax treatment that differs depending on whether contributions were made pre-tax or after-tax. How your pension is taxed in retirement depends on federal rules and on Michigan's state income tax treatment of retirement income.
The IRS explains that the taxable portion of a pension or annuity payment is generally included in income as you receive it, and retirees can use the IRS Tax Withholding Estimator to check whether their withholding is on track (IRS). For Michigan residents, rules around taxing public pension income have changed over time, so current-year guidance matters.
When in doubt, the municipal employees' retirement system of michigan can confirm how your specific contributions were reported.
A practical scenario: a newly retired clerk receiving monthly pension payments may need to adjust federal withholding by filing a new W-4P form, or face an unexpected tax bill in April.
How to apply this: Before your retirement date, confirm with MERS how your contributions were taxed and set your withholding elections accordingly.
Frequently Asked Questions About municipal employees' retirement system of michigan
What happens to my MERS pension if I change jobs to a non-participating employer?
If you leave for an employer outside the system, your accrued benefit does not disappear. You may have options including a deferred pension, a refund of contributions, or a rollover to an eligible plan, depending on your plan's terms.
The municipal employees' retirement system of michigan evaluates each case against your employer's specific contract, so request a separation packet before deciding.
Can I work while receiving a MERS pension?
Yes, in many cases — but re-employment rules matter. Returning to work for a participating employer in a covered position can affect payment of your pension, while working for a non-covered employer typically does not. The municipal employees' retirement system of michigan publishes re-employment provisions by plan type, and violations can trigger benefit adjustments.
How do survivor benefits work if I die before retirement?
Most MERS defined benefit plans include provisions that pay an eligible beneficiary or survivor if the member dies before retirement. Eligibility usually depends on factors like marriage duration and vested status. Because the municipal employees' retirement system of michigan administers these rules under employer-specific contracts, review your plan's survivor benefit section and confirm your beneficiary record is accurate.
How is the municipal employees' retirement system of michigan funded?
The system is funded through a combination of employer contributions, employee contributions where applicable, and investment returns on plan assets. Each participating employer's funding level reflects its own actuarial valuation. The municipal employees' retirement system of michigan reports funded status through audited financial statements, which members and employers can request for review.
Where can I get help if my benefit statement looks wrong?
Start with your employer's HR or payroll office, since many discrepancies come from reporting errors in service or salary data. If the issue persists, contact the municipal employees' retirement system of michigan directly through its member services team. The Michigan Department of Treasury (michigan.gov/treasury) also provides general information on public retirement systems in the state.
