Michigan Income Tax Calculator
Michigan’s flat 4.25% state rate skips the federal standard deduction entirely and uses a personal exemption instead — and if you live or work in Detroit, Grand Rapids, Lansing, Flint, or Saginaw, a separate city income tax stacks on top. This Michigan paycheck calculator covers all of it.

How Michigan Income Tax Actually Works
Michigan has run a flat-rate income tax since 1967, and the current 4.25% rate is reviewed every year through a statutory formula: if state general fund revenue grows faster than inflation, the rate is supposed to drop automatically. Michigan Treasury confirmed in April 2026 that the trigger was not met for the 2026 tax year, so the rate holds at 4.25% — the same rate that applied for 2025, after a brief one-year dip to 4.05% in 2023 that the Michigan Supreme Court ruled was a single-year reduction only.
The detail that surprises almost everyone moving from another state: Michigan does not offer a standard deduction at all. Michigan taxable income is built from your federal adjusted gross income, not your federal taxable income — meaning the $15,750 (or $31,500 married) federal standard deduction that lowers your IRS bill has zero effect on your Michigan bill. Instead, Michigan grants a flat personal exemption of $5,800 per person for the 2025 tax year (you, your spouse if filing jointly, and each dependent), adjusted annually for inflation.
The Michigan city income tax layer: 24 Michigan cities, including Detroit, Grand Rapids, Lansing, Flint, and Saginaw, levy their own municipal income tax under Michigan’s Uniform City Income Tax Act — separate from both the state return and from each other. Detroit’s resident rate of 2.4% is among the highest city income taxes in the country, while non-residents who only work in Detroit pay exactly half that, 1.2%. City returns are filed separately from your MI-1040, and (apart from Detroit, which Treasury processes jointly with the state) most cities administer their own filing entirely.
Frequently Asked Questions
Michigan’s flat individual income tax rate is 4.25% for the 2025 tax year, and the Michigan Department of Treasury confirmed in April 2026 that it remains 4.25% for the 2026 tax year as well, since the statutory rate-reduction trigger was not met.
No. Michigan does not offer a standard deduction. Michigan taxable income starts from your federal adjusted gross income, and the only reduction is the personal exemption — $5,800 per person for the 2025 tax year.
Detroit residents pay a 2.4% city income tax on top of the 4.25% state rate. Non-residents who work in Detroit but live elsewhere pay half that rate, 1.2%, and may also owe city tax to their own city of residence if it levies one.
Of Michigan’s 24 cities with a local income tax, the largest besides Detroit include Grand Rapids (1.5% resident / 0.75% non-resident), Lansing (1% / 0.5%), Flint (1% / 0.5%), and Saginaw (1.5% / 0.75%). Most of Michigan, including its suburbs and rural areas, has no city income tax at all.
Social Security benefits are fully exempt from Michigan tax for everyone, regardless of age. Pension and retirement account income is taxed differently depending on your birth year under Michigan’s tiered retirement subtraction rules.
Methodology: Calculations use Michigan’s 2025 flat 4.25% individual income tax rate (confirmed unchanged for 2026 by Michigan Treasury), the $5,800 personal exemption per person, the 2025 IRS federal tax brackets and Child Tax Credit rules, and 2025 Social Security (6.2% to the $176,100 wage base) and Medicare (1.45% + 0.9% additional Medicare tax) rates. City income tax is estimated for Detroit, Grand Rapids, Lansing, Flint, and Saginaw based on published resident/non-resident rates; verify your exact city and rate, since 24 Michigan cities levy their own income tax.
