- Michigan grants no standard deduction, so the rate applies from the first dollar of taxable income.
Not included in this figure
- Personal exemption: $5,900 single, $11,800 joint, $5,900 per dependent — not applied — this estimate is therefore slightly high
- Local and municipal income tax: No local rates are modelled. — a resident of a city that levies its own income tax will owe more
- State credits, subtractions and addbacks: State-specific adjustments to income are out of scope. — can move the result in either direction
Tax year 2026. Michigan tax only — federal tax is separate. Rate figures as of January 1, 2026.
How Michigan taxes income
Michigan charges flat 4.25%. State tax is a separate calculation from your federal return rather than a share of it — Michigan sets its own schedule and its own definition of taxable income.
- Rate: 4.25% on all taxable income
- Brackets: A single rate, so no bracket to cross
- Standard deduction: None — the rate applies from the first dollar
- Personal exemption: $5,900 single, $11,800 joint, $5,900 per dependent (not applied here)
Rate figures are as of January 1, 2026 and were checked against Michigan Department of Treasury on 2026-09-28 — flat 4.25% against the Michigan Treasury notice determining the 2026 rate. Michigan can still change them mid-year.
What catches people out in Michigan
- Michigan applies one rate of 4.25% to all taxable income, so your marginal and average state rates are the same and extra income does not push you into a higher band.
- Michigan grants no state standard deduction, so its rate applies from the first dollar of taxable income. That is why a low headline rate here is not as low as it looks next to a state with a large deduction.
- Local income taxes are excluded; Michigan's average local rate is 0.16% of AGI (footnote a). Michigan temporarily cut its rate to 4.05% for tax year 2023 and reverted to 4.25% for 2024 onward.
What this estimate leaves out
Three things are deliberately outside this calculation, because they change more often than annually and a confident wrong number does real damage on a tax page.
- The personal exemption — $5,900 single, $11,800 joint, $5,900 per dependent — is not applied, so the figure runs slightly high.
- Local and city income tax is not included. New York City is the significant one nationally.
- State-specific credits, subtractions and income addbacks are out of scope and can move the result either way.
If you have income in India, Michigan is where treaty relief runs out
States are not parties to the India-US tax treaty, and a state credit for "taxes paid to other jurisdictions" almost always means other US states rather than other countries.
So NRO interest, Indian rental income or a gain on Indian shares can be taxed by Michigan with no credit for the Indian tax deducted at source — even though Form 1116 largely neutralises that same tax federally.
The treatment is not uniform across states, so treat this as the general position rather than as Michigan's confirmed one, and check the credit rules with Michigan Department of Treasury before relying on relief.

Frequently Asked Questions
Does Michigan have a state income tax?
Yes — Michigan charges flat 4.25%. Figures are as of January 1, 2026.
Is Michigan tax on top of federal tax?
Federal tax applies regardless of which state you live in, and is calculated separately. Michigan tax is additional to it, and uses its own brackets and its own deduction rather than a share of your federal bill.
I moved to or from Michigan during the year. Does this work?
Not directly. A part-year move usually means a part-year return in each state with income apportioned between them, and the state you left applies its own residency test rather than accepting a new address. Use this to size the rates, then treat the apportionment as a separate question.
What filing statuses does this cover?
Single and married filing jointly. Those are the only two schedules published in the sourced data behind this calculator, so head of household and married filing separately are left out rather than approximated from a schedule nobody verified.
