How Michigan Income Tax Works

Michigan taxes income at a flat 4.25% for tax year 2026 — one rate, no brackets. Unlike most flat-tax states, Michigan offers no standard deduction; instead, it gives every taxpayer and dependent a generous $5,900 personal exemption (adjusted annually for inflation). Everything left after exemptions is taxed at 4.25%.

  • One flat rate: 4.25%. Every dollar of Michigan taxable income is taxed at 4.25% — no brackets, so your marginal rate is always the same.
  • No standard deduction. Michigan skips the standard deduction most states use; the personal exemption does all the work instead.
  • Personal exemption: $5,900 per person. Single filers subtract $5,900; joint filers subtract $11,800; each dependent subtracts another $5,900. The amount adjusts for inflation each year.
  • City income tax is extra. Michigan lets cities levy their own income tax — Detroit charges 2.4% on residents and 1.2% on nonresidents who work there, and about two dozen other cities charge 1% or less. This calculator models the state portion only.
MI taxable income = gross income − personal exemptions ($5,900 × number of people)
MI state tax = taxable income × 4.25%
(taxable income cannot go below $0)

Worked Example: Single, $80,000 Gross Income

Calculation Amount
Personal exemption (single) $5,900
MI taxable income $80,000 − $5,900 $74,100
MI state tax $74,100 × 4.25% $3,149.25
Effective rate $3,149.25 ÷ $80,000 3.94%

Frequently Asked Questions

No. Michigan is unusual among flat-tax states in that it offers no standard deduction at all. Instead, the $5,900-per-person personal exemption (inflation-adjusted annually) is what shields your first dollars of income from tax.

Possibly. About two dozen Michigan cities levy their own income tax — Detroit charges 2.4% on residents (1.2% on nonresidents who work in the city), and most others charge 1% or less on residents. This calculator models only the state portion, so add your city rate if one applies.

$5,900 per person — $5,900 for a single filer, $11,800 for a married couple filing jointly, plus $5,900 for each dependent. The exemption is adjusted for inflation each year by the Michigan Department of Treasury.

It depends on your income. Ohio’s effective rate (2.75% above $26,050) and Illinois’ 4.95% flat rate bracket Michigan on both sides. Because Michigan has no standard deduction, low-income filers can face a higher effective rate than in Ohio; at higher incomes the generous $5,900 exemption keeps Michigan competitive.

Partially. Michigan exempts Social Security benefits and offers a pension/retirement income deduction (the “pension subtraction”) with limits that vary by age and birth year. Retirees should verify the current subtraction rules with the Michigan Department of Treasury — this calculator models wage income only.

No — it is an estimate for planning purposes only. It models the 4.25% flat rate with personal exemptions; credits, city taxes, and retirement subtractions can change your actual liability. Consult a licensed tax professional for your return.
