What is the Michigan state income tax rate in 2026?
Michigan taxes income at a flat 4.25% in 2026. Example: a married couple, both 70, with $40,000 of Social Security, a $30,000 private pension and $30,000 of IRA withdrawals ($100,000 in all; the pension and IRA money split evenly between them) owes $0 of Michigan income tax (0.0% of their income) and $5,087 of federal tax; a single 62-year-old with $24,000 of Social Security, an $18,000 pension and $18,000 of IRA withdrawals ($60,000 in all) owes $0 to Michigan and $4,111 federal. The schedule, how Michigan treats each kind of retirement income, and its local taxes follow.
How Michigan taxes retirement income in 2026
| Standard deduction or personal exemption | $5,900 single, $11,800 married filing jointly, and the single amount for head of household. (Michigan Department of Treasury; rules) |
|---|---|
| Social Security | Social Security benefits are fully exempt: none of the federally taxable amount enters the state base. (Michigan Department of Treasury; rules) |
| Pensions, annuities and IRA/401(k) withdrawals | Pension, annuity and IRA/401(k) distributions: up to $67,610 excluded per taxpayer ($135,220 on a joint return) at any age. (Michigan Department of Treasury; rules) |
| Government pensions | For a filer (on a joint return, the older spouse) 81 or older — born before 1946 — public pensions are subtracted without limit. Otherwise public pensions follow the rules for other retirement income above. (Michigan Department of Treasury; rules) |
| Capital gains | Net long-term gain is taxed as ordinary income. Short-term gains are ordinary income. (Michigan Department of Treasury; rules) |

In QuantCalc's 51-state planner study — one married couple, both 60, $2M, $80,000 a year to spend after tax, 10,000 paths per jurisdiction — the median path in Michigan pays $162,597 of federal and state income tax and Medicare IRMAA over 30 years, with no Michigan state income tax in any year. That ranks #1 of 51 (tied with 15 others) by lifetime tax (1 = lowest). The plan succeeds in 84.05% of paths. State tax is part of the optimization here — the playbook below shows the federal-state-ACA stack.
The MI verdict
For a retiree planning withdrawals in 2026, Michigan is a middle-of-the-road state for retirement taxation. One flat bracket, with retirement income exemptions tiered by birth year.
Michigan allows a retirement-income exclusion of up to $135,220 for a couple at any age. A traditional→Roth conversion draws on that same exclusion from age 60, so converting inside the cap can cost nothing at the state level.
Worked example: $30k Roth conversion in Michigan
Consider a married couple age 58 in Michigan with $75,000 of wages (their MAGI), both on ACA Marketplace coverage. They want to convert $30,000 from a traditional IRA to a Roth. The Michigan state tax on that conversion is $1,275 — 4.3% of the amount converted. Federal income tax adds another $3,600 — the whole conversion is taxed in the federal 12% bracket. And because the conversion pushes their MAGI to $105,000 — over the 400% FPL cliff of $84,600 — they lose their full ACA premium tax credit, $17,555 a year at Michigan's average benchmark Silver premium. Total cost of the $30,000 conversion: $22,430, or an effective 74.8% marginal rate. Each Michigan tax figure for a conversion on this page is QuantCalc's state tax engine run on the couple's whole 2026 Michigan return twice, without the conversion and with it, with every amount split evenly between the two spouses, so Michigan's own brackets, deductions, exemptions and credits are all applied. The federal-state-ACA stack matters in Michigan.
Cost breakdown
| Component | Amount |
|---|---|
| Federal income tax (12% bracket) | $3,600 |
| Michigan state income tax | $1,275 |
| ACA premium tax credit clawback | $17,555 |
| Total cost on $30,000 conversion | $22,430 (74.8% effective) |
Scenario B (moderate): cliff-aware $34.6k conversion in Michigan
A Michigan couple aged 60, both on Marketplace coverage with $50K wages converts $34,600, which lifts their MAGI to exactly the $84,600 400% FPL cliff: still eligible, and they keep a premium tax credit of $18,230 a year. One more dollar of conversion would cost all of it. State tax: $0 — Michigan's retirement-income exclusion covers the whole conversion for this couple at this age. Federal income tax added: $4,012 (the whole conversion is taxed in the federal 10%–12% brackets). ACA PTC preserved. Total cost: $4,012, or 11.6% effective. In moderate-tax states, the conversion size is bounded by both the IRMAA two-year lookback and the ACA cliff — not state tax alone.
What the planner's Monte Carlo says about Michigan
QuantCalc Research ran one married couple through QuantCalc's retirement planner in each of the 51 jurisdictions: both 60, $2,000,000 ($1,400,000 traditional, $600,000 Roth), a 60/40 portfolio, $80,000 a year to spend after tax for 30 years, no Social Security, 10,000 paths each. The planner's federal and state tax engines price every year, and it picks the withdrawals and Roth conversions. Here is Michigan beside the lowest- and highest-tax results:
| Metric | Michigan | No state tax (16 jurisdictions) | Oregon (highest) |
|---|---|---|---|
| Median lifetime tax, federal + state + IRMAA (30y) | $162,597 | $162,597 | $309,718 |
| State income tax (30y, sum of yearly medians) | $0 | $0 | $146,914 |
| State income tax in the first year (age 60) | $0 | $0 | $5,838 |
| 30-year success rate | 84.05% | 84.05% | 80.61% |
| Median balance at 90 | $2,153,150 | $2,153,150 | $1,801,272 |
| Rank by lifetime tax (of 51, 1 = lowest) | #1 | #1 | #51 |
Across all 51 jurisdictions the success rate runs from 80.61% to 84.05%: for this couple the state changes the tax bill far more than the odds of the money lasting. Dollars are today's dollars.

How Michigan treats capital gains in retirement
Michigan taxes long-term capital gains as ordinary income at the same top bracket rate (4.25%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 4.25% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
Why the ACA cliff hits hard in Michigan
The 400% federal-poverty-level cliff is federal, not state-specific — but its dollar impact depends on the benchmark Silver-plan premium in your county. Michigan's Marketplace pricing and your household composition determine the size of the subsidy at risk. A couple aged 58 with MAGI of exactly $84,600 still has $16,599 a year of premium tax credit at Michigan's average benchmark Silver premium, and all of it is on the line. With the 2021–2025 enhanced credit expired, $1 of additional MAGI above 400% FPL eliminates the entire credit.
For 2026 the 400% FPL threshold is:
Roth conversion strategy for Michigan
The MI-specific playbook depends on tier:
- Identify your cliff distance. Compute MAGI from all income sources (wages, capital gains, interest, dividends, traditional withdrawals). Find your headroom under 400% FPL. Use the live cliff widget above for a quick check.
- Stay under the cliff if you can. In Michigan at 4.25%, the marginal cost of going over the cliff is federal tax + state tax + full PTC clawback. The break-even conversion size is smaller than in tax-free states.
- If you must go over, convert big. Once you've crossed the cliff, additional conversion dollars only cost federal + state tax (no incremental PTC loss). A "rip the bandage" conversion year can be efficient if you have many traditional dollars to move.
- Coordinate with capital gains and the 0% LTCG bracket. Michigan taxes long-term capital gains as ordinary income at the same top bracket rate (4.25%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 4.25% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
- Plan ahead for IRMAA. The IRMAA Medicare premium surcharge has a 2-year lookback. A Michigan resident in their early 60s converting today will see IRMAA implications at 65. See RMD + IRMAA calculator for the lookback math.

Each move changes three bills at once: the federal return, the Michigan return and, for anyone on Medicare, the IRMAA surcharge the 2026 income sets for 2028. Example: a married couple, both 72, with a $40,000 pension, $50,000 of Social Security, a $30,000 IRA withdrawal and $10,000 of long-term gains already realized in 2026, the pension, the IRA money and the conversion split evenly between them on the state return. Each row is that year with one move made, against the same year without it (negative = less tax).
| Move (by December 31, 2026) | Federal tax | Michigan tax | IRMAA in 2028 |
|---|---|---|---|
| Convert $25,000 to a Roth IRA | $3,165 | $0 | $0 |
| Send $10,000 of the IRA withdrawal to charity as a QCD | −$1,200 | $0 | $0 |
| Harvest a $5,000 loss against the year's gains | $0 | $0 | $0 |
