Michigan Income Tax Calculator + City Tax (2026)

This Michigan income tax calculator estimates what you owe the state for tax year 2026 — and, unlike the national tools, it adds Grand Rapids or Walker city income tax on top. Michigan is a flat-rate state, so the arithmetic itself is simple. What catches West Michigan out is the second bill: two dozen Michigan cities levy their own income tax, and almost no calculator online includes them.

How Michigan income tax works in 2026

Michigan charges a flat 4.25% income tax for tax year 2026. There are no brackets and no graduated rates — a machinist earning $52,000 and a business owner earning $520,000 are taxed at exactly the same percentage. That makes Michigan one of the easier state returns to estimate, and it is why a calculator can give you a genuinely close number from three inputs.

The part that moves your bill is the personal and dependency exemption. For 2026 it is $5,900 per exemption, up from $5,800 in 2025. You claim one for yourself, one for your spouse if you file jointly, and one for each dependent — the same dependents you claim on your federal return. Every exemption comes off your income before the 4.25% is applied, which is why your effective rate is always lower than the headline rate.

So the formula is short: (Michigan taxable income − $5,900 × exemptions) × 4.25%. A married couple with two children and $95,000 of income subtracts $23,600, pays 4.25% on $71,400, and owes Michigan about $3,035 — an effective state rate of 3.2%, not 4.25%.

What counts as Michigan taxable income

Michigan does not start from scratch. Your Michigan return begins with your federal adjusted gross income, then applies a short list of state-specific additions and subtractions. For most working households the two numbers are close enough that entering your AGI in the calculator above gives a reliable estimate.

Michigan taxes:

• Wages, salary, tips and bonuses
• Self-employment and Schedule C profit
• Interest, dividends and capital gains — at the same 4.25%, with no preferential rate
• Rental income and flow-through income from a partnership or S corporation
• Unemployment compensation

Michigan does not tax:

• Social Security benefits
• Military pay, including Reserve and National Guard pay, and military pensions
• Qualifying pension and retirement income, up to $67,610 for a single filer and $135,220 on a joint return in 2026
• Interest on U.S. Treasury obligations

One recent change matters if you bought equipment. Public Act 24 of 2025 decoupled Michigan from several federal Internal Revenue Code provisions, so certain deductions created by the federal One Big Beautiful Bill Act are written off more slowly on a Michigan return than on a federal one, starting with tax year 2025. The practical effect is an add-back on the Michigan side: a contractor who expensed a new truck in full federally can still show more income to Michigan than to the IRS. It is exactly the kind of gap a flat-rate calculator cannot see.

That retirement subtraction is large enough to change the answer completely for a retired household, and the calculator above deliberately does not model it — the eligibility rules turn on birth year, the source of the benefit, and the age of the older spouse on a joint return. If most of your income is retirement income, treat the estimate as an upper bound and have someone run the actual Michigan individual tax return.

Grand Rapids and Walker city income tax

This is the part the national calculators miss. Twenty-four Michigan cities levy an income tax of their own, filed separately and due April 30 — a different form, a different deadline, and a bill most people do not see coming. Two of them sit in 4K's back yard.

Residents — anyone whose home is inside the city limits, renters included — are taxed on essentially everything that is taxable federally, no matter where they earned it. Drive to Holland every day for work and live in Grand Rapids, and Grand Rapids still taxes those wages at 1.5%.

Non-residents are taxed only on what they earn inside the city limits, at half the resident rate. If you live in Grandville, Jenison or Wyoming and work downtown, you owe Grand Rapids 0.75% on the wages you earned there. Days you genuinely worked somewhere else can come out — but both cities require a work log and, in Walker's case, a signed letter from your employer.

Cities are narrower than the state in one helpful way: Grand Rapids and Walker do not tax Social Security, pensions, IRA distributions after 59½, unemployment compensation, or military pay. They are also narrower on deductions — neither allows the federal standard deduction, mortgage interest, or charitable contributions. What they do allow is IRA contributions, self-employed retirement plans, alimony paid, and a short list of employee business expenses.

We prepare city returns for every Michigan city that has an income tax, and in practice that means Grand Rapids and Walker week in and week out. If you have moved between cities mid-year, changed jobs, or started working remotely for a downtown employer, the city return is where it gets fiddly — see the Grand Rapids and Michigan tax deadlines in our tax center, or just ask.

A worked example: a Grand Rapids contractor

Dave runs a two-truck plumbing company out of his house on the northeast side of Grand Rapids. He's married, has two kids, and after expenses his Schedule C nets $95,000 for 2026. Here is the whole calculation.

That is an effective rate of 4.7% on Dave's income — and the city portion is nearly a third of it. Had Dave's house been a few streets north, inside Walker instead, the city bill would be $926 rather than $1,389. Same income, same family, $463 of difference decided by a city line on a map.

Two things this example does not show, and Dave still owes both: federal income tax, and self-employment tax on that $95,000 of Schedule C profit. Between them they dwarf the numbers above, which is the real reason a contractor's quarterly estimates need to be set deliberately rather than guessed.

What this calculator does not include

Every calculator makes simplifying assumptions. Most of them do not tell you which ones. Here are ours, so you know exactly how far to trust the number above.

• Federal income tax and self-employment tax. This estimates Michigan and city tax only. For most households the federal bill is several times larger.
• Retirement and Social Security subtractions. The rules turn on birth year and benefit source, so a retired household's real Michigan tax is usually far lower than shown.
• Credits. The Michigan homestead property tax credit, the home heating credit, and the Michigan Earned Income Tax Credit all reduce what you actually pay, and none are applied here.
• Special exemptions. Michigan grants additional exemptions in specific situations, and dependents of another taxpayer are treated differently.
• Michigan's other 22 taxing cities. Twenty-four Michigan cities levy an income tax, and this calculator prices the two in Kent County. If you live or work in Albion, Battle Creek, Benton Harbor, Big Rapids, Detroit, East Lansing, Flint, Grayling, Hamtramck, Highland Park, Hudson, Ionia, Jackson, Lansing, Lapeer, Muskegon, Muskegon Heights, Pontiac, Port Huron, Portland, Saginaw or Springfield, the Michigan figure above still holds — the city line does not.
• Part-year residency and other-city credits. Moving during the year, or living in one taxing city while working in another, changes both returns.
• Michigan additions and subtractions beyond the basics, including 529 contributions and the flow-through entity tax.

None of that makes the estimate useless — it makes it an estimate. If the number matters, because you are setting quarterly payments, deciding on an entity election, or looking at a bill you were not expecting, that is the point at which it is worth having a CPA look at the actual figures.

FAQ

How much is Michigan state income tax in 2026?

Michigan charges a flat 4.25% income tax for tax year 2026. There are no brackets — someone earning $40,000 and someone earning $400,000 pay the same rate. Before the rate is applied you subtract $5,900 for every personal and dependency exemption you claim, so your effective rate is always lower than 4.25%.

How do I calculate my Michigan income tax?

Start with your federal adjusted gross income, apply Michigan's additions and subtractions to get Michigan taxable income, subtract $5,900 for each exemption you claim, then multiply what is left by 4.25%. A married couple with two children and $95,000 of income subtracts $23,600 in exemptions and pays 4.25% on $71,400, which is $3,035.

What is the Michigan personal exemption for 2026?

The Michigan personal and dependency exemption is $5,900 per exemption for tax year 2026, up from $5,800 in 2025. You claim one for yourself, one for your spouse on a joint return, and one for each dependent. Michigan also has special exemptions that are claimed on the MI-1040 and are not covered by this calculator.

Does Michigan have a city income tax?

Yes. Two dozen Michigan cities levy their own income tax on top of the state's 4.25%. In West Michigan the two that matter most are Grand Rapids, at 1.5% for residents and 0.75% for non-residents, and Walker, at 1% for residents and 0.5% for non-residents. Both allow a $600 exemption per person, and both are filed separately from your Michigan return.

Do I pay Grand Rapids income tax if I work there but live somewhere else?

Yes. Grand Rapids taxes non-residents at 0.75% on the wages and business income they earn inside the city limits, even if they live in Grandville, Wyoming, or Jenison. Days you genuinely worked outside the city are not taxable, but you have to document them. Grand Rapids non-resident returns are due April 30.

Is Social Security taxed in Michigan?

No. Michigan does not tax Social Security benefits, and Grand Rapids and Walker do not tax them either. Michigan also allows a substantial subtraction for qualifying pension and retirement income — $67,610 for a single filer and $135,220 on a joint return in 2026 — which this calculator does not model. If most of your income is retirement income, treat the estimate here as an upper bound.
