How Michigan Income Tax Works
Michigan uses a flat income tax rate of 4.25% for 2026. Every dollar of taxable income above the standard deduction is taxed at the same state rate. Federal income tax still uses the seven-bracket 10%–37% progressive system on top of state.
Michigan's 4.25% flat rate is moderate, but Detroit's 2.4% city tax stacks on top — making it one of the few states where city of residence significantly changes take-home pay.

Michigan has a flat 4.25% state income tax rate for 2026. The rate is the same regardless of income — applied to your taxable income after the standard deduction. Federal rates (10%–37%) layer on top.

What's the difference between effective and marginal tax rate?
Your marginal rate is the rate applied to your last dollar of taxable income — the bracket your top dollar lands in. Your effective rate is your total income tax divided by your total income — the average rate across everything you earned. Effective is always lower than marginal because lower brackets cover the first portions of your income at lower rates.

Does Michigan tax retirement income, Social Security, or capital gains?
Federal rules: long-term capital gains use preferential rates (0%, 15%, 20%) — see our Capital Gains Tax Calculator. Social Security is taxable federally if your combined income exceeds certain thresholds. Michigan's treatment of retirement income, Social Security, and capital gains varies — many states fully or partially exempt Social Security, and some provide pension exclusions. Consult Michigan's Department of Revenue for specifics.
How is this Michigan income tax estimate calculated?
We apply the 2026 federal IRS tax tables (10%–37% across seven brackets) and Michigan's 2026 state tax schedule to your taxable income (gross income minus the standard deduction). The calculator handles wages, self-employment income (with SE tax and the deductible half), and other income; you can also switch to itemized deductions. Tax credits, AMT, and preferential capital gains rates are not modeled — this is an estimate of ordinary income tax only.
