Michigan pension tax rules give uncovered government retirees a choice no other retiree gets: you can deduct your pension under the older tier system’s higher uncovered ceilings, or you can take the fully phased-in private retirement maximum that opened to every taxpayer starting in the 2026 tax year. Running both calculations and picking the larger subtraction can be worth thousands of dollars. The uncovered advantage only works if you tell the state you qualify, which means checking the right box on Form 4884.
Who Counts as an Uncovered Government Retiree
Under MCL 206.30, you qualify as an uncovered government retiree if you receive pension or retirement benefits from a federal, state, or local government job where you did not pay Social Security taxes on your earnings.1Michigan Legislature. Michigan Compiled Laws 206.30 – Taxable Income The test is whether Social Security taxes were withheld from the specific employment that generated your pension. If they were not, Michigan treats that pension as uncovered.
Common examples include retired teachers in Michigan public school systems that opted out of Social Security, certain state police officers, many federal employees hired before 1984 under the older Civil Service Retirement System, and employees of some municipal governments. The classification attaches to the job behind the pension, not to your whole career. A separate private-sector job where you paid into Social Security does not disqualify your government pension from uncovered treatment.
What’s Different for Uncovered Retirees Starting in 2026
Public Act 4 of 2023 finished its four-year phase-in with the 2026 tax year, meaning every Michigan taxpayer regardless of birth year can now claim the full inflation-adjusted private retirement maximum that was once reserved for taxpayers born before 1946.2State of Michigan. Revenue Administrative Bulletin 2026-1 For uncovered retirees, that does not replace the older tier-based option; it sits alongside it. You pick whichever produces the lower tax bill each year.
Taxpayers born before 1946 still have no cap on their public retirement benefit deductions, so the comparison below mainly matters for everyone else.
The Uncovered Tier Amounts
Under the tier system, uncovered retirees who were born between 1946 and 1952, or born after 1952 and retired by January 1, 2013, can claim these base statutory ceilings under MCL 206.30(9)(c):
- Single or married filing separately: $35,000
- Joint return, one uncovered spouse: $55,000
- Joint return, both spouses uncovered: $70,000
These base amounts are adjusted annually for inflation.1Michigan Legislature. Michigan Compiled Laws 206.30 – Taxable Income Uncovered retirees born after 1952 who were not retired by January 1, 2013 and who have reached age 62 but not 67 get a smaller subtraction of $15,000 per qualifying spouse under the tier system.3State of Michigan. 2025 Tier III
The Fully Phased-In Deduction
The alternative is the inflation-adjusted private retirement maximum, which any taxpayer can now elect. For the 2025 tax year it was $65,897 for single filers and $131,794 for joint returns.2State of Michigan. Revenue Administrative Bulletin 2026-1 The Michigan Department of Treasury publishes an updated figure each year, so pull the current number before you file.
Which Method Wins
Run both calculations with the current year’s inflation-adjusted amounts. A few patterns tend to hold:
- Single uncovered filers often come out ahead on the phase-in amount, because the private retirement maximum has historically exceeded the $35,000 uncovered single ceiling even after inflation adjustments.
- Joint returns where both spouses are uncovered can favor the tier amount, depending on how the inflation adjustments compare in a given year.
- The Michigan Standard Deduction ($20,000 single, $40,000 joint) rarely beats either pension option for retirees drawing substantial pensions, but it can win when retirement income is modest and other income is higher.
Form 4884 calculates both the tier and phase-in subtractions side by side, and you select the larger.4Michigan Department of Treasury. 2025 Michigan Retirement and Pension Schedule (Form 4884) Instructions If the standard deduction turns out to be best, the Michigan forms apply a residual standard deduction automatically; no separate election.
Income That Does Not Qualify
Not every dollar on a 1099-R counts as qualifying retirement income. Michigan treats defined benefit pensions, IRA distributions, and most defined contribution plan payments included in your federal adjusted gross income as qualifying benefits.5Michigan Department of Treasury. Retirement and Pension Benefits
Deferred compensation generally does not qualify. Distributions from 457 plans, 401(k) plans where you controlled how much to defer, and amounts reported as wages on a W-2 are not eligible for the pension subtraction.6State of Michigan. Are Distributions From a Deferred Compensation Plan an Allowable Subtraction? This catches uncovered retirees who paired a defined benefit pension with a government 457(b). The pension subtracts; the deferred comp payout usually does not.
Filing Form 4884 and Triggering the Uncovered Limits
Form 4884 is the Michigan Retirement and Pension Schedule, and it is the only way to claim the subtraction. You attach it to Michigan Schedule 1 and your MI-1040.7Michigan Department of Treasury. 2025 Michigan Retirement and Pension Schedule (Form 4884)
Gather every federal Form 1099-R you received for the year. You will need the payer’s federal employer identification number and the Box 7 distribution code from each one.4Michigan Department of Treasury. 2025 Michigan Retirement and Pension Schedule (Form 4884) Instructions Most normal retirement distributions carry code 7, which the IRS uses for recipients age 59½ or older.8Internal Revenue Service. Instructions for Forms 1099-R and 5498
Each 1099-R gets its own line on Form 4884: payer name, gross distribution, EIN, and distribution code. Combine entries on one line when they share a payer and a distribution code. Enter birth years so the form can apply the right brackets.
The critical step for uncovered retirees is the checkbox indicating your pension came from government employment not covered by Social Security. Checking it is what triggers the higher uncovered ceilings. Miss the box, and the form defaults to the lower covered limits.
Documentation to Keep
Michigan does not require you to send proof of uncovered status with your return, but keep documentation ready for a possible audit. The clearest proof is Form SSA-1945, which state and local government employers have been required to give employees hired since January 1, 2005 when the job is not covered by Social Security.9Social Security Administration. Statement Concerning Your Employment in a Job Not Covered by Social Security
If you were hired before 2005 or never received an SSA-1945, other records work: a letter from your pension administrator confirming no Social Security withholding, W-2s from the relevant years showing zero Social Security wages in Box 3, or your Social Security earnings statement from ssa.gov showing no credited earnings during that employment. Your plan’s summary plan description may also confirm that the plan operates outside Social Security coverage.
How the Social Security Fairness Act Affects Your Michigan Return
Uncovered government retirees used to face the Windfall Elimination Provision, which cut their Social Security retirement benefits, and the Government Pension Offset, which could eliminate spousal and survivor benefits. Both were repealed when President Biden signed the Social Security Fairness Act on January 5, 2025, retroactive to benefits payable for January 2024 and later.10Social Security Administration. Program Explainer: Windfall Elimination Provision
If the repeal gave you larger Social Security checks, that income flows through to your federal AGI and can then be subtracted separately on your Michigan return. Under 2025 PA 24, for tax years 2026 through 2028, taxpayers eligible for the standard deduction can subtract both their Social Security income and a full standard deduction.2State of Michigan. Revenue Administrative Bulletin 2026-1 For uncovered retirees who also earned some Social Security credits from covered employment elsewhere, the combination of a restored benefit and Michigan’s expanded subtractions can meaningfully lower the state tax bill.
