A single filer earning Michigan's median household income of $79,460 owes about $3,126 in Michigan state income tax — an effective state rate of 3.93%. That is state tax only, on top of federal income tax and FICA.

Based on 2026 Michigan rules and 2026 federal rules, with the standard deduction and no other adjustments. Median income is the 2024 Census figure.

Income tax in Michigan

Michigan levies a flat 4.25% income tax for 2026 — Treasury's April 2026 determination found general fund revenue actually fell, so the revenue-trigger formula produced no rate cut again this year. There is no standard deduction, but each filer gets a $5,900 personal exemption, up from $5,800. About two dozen Michigan cities, including Detroit, levy local income taxes that are not included in this estimate.

Michigan income tax structure (2026)

Michigan taxes income at a flat 4.25% after a personal exemption of $5,900. Every taxable dollar is taxed at the same rate, so your marginal and effective state rates converge as income rises.

Estimates for general informational purposes only; not tax advice. Michigan figures are simplified (credits, local taxes, and AGI adjustments vary) and should be verified with the state Department of Revenue. This estimate does not model Michigan city income taxes, including Detroit's resident tax. Michigan's flat 4.25% is applied with the $5,900-per-filer exemption and no standard deduction — itemized deductions and Michigan credits are not modelled.
