Work in Michigan, Live in Indiana: How Taxes Work

Reciprocity

Do Michigan and Indiana Have a Tax Reciprocity Agreement?

Yes. Michigan and Indiana are on each other's short list of reciprocal states. The Michigan Department of Treasury explains that reciprocity agreements provide a resident will remain subject to the income tax of their respective home state, regardless of where the services were performed. Michigan lists Illinois, Indiana, Kentucky, Minnesota, Ohio, and Wisconsin as its reciprocal states.

Indiana's Income Tax Information Bulletin #33 mirrors this arrangement. Indiana has established reciprocity agreements with Kentucky, Michigan, Ohio, Pennsylvania, and Wisconsin covering the collection of income tax from nonresidents employed in Indiana. The bulletin also notes that Indiana residents who work in states with reciprocity receive identical treatment from those states.

The practical result for an Indiana resident commuting to a Michigan job: Michigan does not tax your wages, Michigan withholding is not required, and your entire wage income belongs on your Indiana resident return. The reciprocity only covers salaries, wages, tips, and commissions paid by an employer. Business or self-employment income earned in Michigan is not covered and may still be taxable there.

Withholding Setup

How Do I Stop Michigan Withholding as an Indiana Resident?

Give your Michigan employer a completed Form MI-W4 and check the line for residents of a reciprocal state (Illinois, Indiana, Kentucky, Minnesota, Ohio or Wisconsin) while working in Michigan. That tells payroll not to withhold Michigan income tax. Michigan does not issue separate nonresidency certificates; the employer may develop its own form or get a letter from you.

Indiana's Form WH-47 is not your form: it is used only by residents of reciprocal states who work in Indiana. What matters on the Indiana side is withholding. Indiana's resident booklet says employers in reciprocal states will normally withhold Indiana state tax from your wages because of the agreement, so ask your Michigan employer to withhold Indiana state tax and your county's local income tax (LIT). If it does not, plan for a balance due or estimated payments.

Filing Obligations

Which Tax Returns Do I File as an Indiana Resident Working in Michigan?

File one return in most years: Indiana Form IT-40 as a full-year resident. Report all wages from every source, including your Michigan employer, on the Indiana return. Because Michigan reciprocity removes the Michigan state tax on your wages, no Michigan filing is required as long as wages are your only Michigan income.

Michigan's Department of Treasury confirms this in its FAQ: no, you are not required to file a Michigan return if salaries, wages and other employee compensation was your only Michigan income. The exception is when Michigan tax was mistakenly withheld and you want it back. In that case, file MI-1040 with Schedule 1, Schedule NR, and Schedule W to request a refund.

Any Indiana state or county tax your Michigan employer withheld is credited on your IT-40 against the tax due.

Both the Michigan and Indiana individual returns are due April 15. Indiana's own extension runs later than the federal one: Form IT-9 or a federal Form 4868 extended the 2025 Indiana filing time to November 16, 2026.

Reciprocity Mechanics

How Does Reciprocity Prevent Double Taxation?

Reciprocity is a cleaner arrangement than the credit-for-tax-paid mechanism used between non-reciprocal states. Michigan agrees not to tax the wages of an Indiana resident earned in Michigan. Indiana agrees not to tax the wages of a Michigan resident earned in Indiana. Both states enforce this through payroll withholding rules.

Indiana's Bulletin #33 sets the withholding side of the deal from the Indiana perspective: the withholding of Indiana income taxes is required for all nonresidents employed in Indiana, except for legal residents of states complying with Indiana's reciprocity statute, IC 6-3-5-1. Michigan's rule mirrors it: a nonresident is taxed only on compensation for services performed in Michigan, and reciprocal-state residents do not pay Michigan tax on those wages.

Because the wages are taxed only once, at the Indiana resident rate, the credit for taxes paid to other states (IT-40 Schedule 6, line 5) plays no role for them. A different line of Schedule 6 matters if you pay a Michigan city income tax; see the section on city taxes below.

The arrangement only covers salaries, wages, tips, and commissions from an employer. Rental income, business profits, capital gains, and other income from Michigan sources fall outside reciprocity and follow their own sourcing rules.

County Tax

Do I Owe Indiana County Tax on My Michigan Wages?

Yes. Indiana's local income tax (LIT) applies to residents by county, and for an Indiana resident it covers your wages wherever you earn them, including in Michigan. Departmental Notice #1 sets the timing rule: both the county of residence and the county of principal business or employment are determined on January 1 of the year your tax year begins.

So the Indiana county you lived in on January 1 sets your rate for the whole year. Common counties for commuters to southwest Michigan include St. Joseph (1.75% for 2026) and LaPorte (1.45%). Rates are published each year in Departmental Notice #1.

If your Michigan employer does not withhold Indiana state and county tax, expect a balance at filing time. Indiana expects estimated payments if you think withholding will not cover your liability and you expect to owe more than $1,000 when you file.

Worked Example: Indiana Resident Earning $65,000 from a Michigan Employer

Single filer, St. Joseph County resident on January 1, 2026, all wages from a Michigan job in a city without an income tax, MI-W4 on file. County tax figured on Indiana taxable income after the exemption. Approximate.

Remote Work

What If I Work from Home in Indiana for a Michigan Employer?

Days you work remotely from your Indiana home are Indiana-source income, not Michigan-source income. At the state level, Michigan taxes a nonresident only on compensation for services performed in Michigan, so there is no convenience rule pulling those days back. Detroit is an exception for its city tax: the city says nonresident taxpayers based in Detroit who work from home cannot count those days as days worked outside Detroit.

For a fully remote Indiana employee of a Michigan employer, Michigan wage tax does not apply because the services are performed in Indiana. Reciprocity is not even the operative rule here; ordinary sourcing puts the wages in Indiana. For a hybrid worker who splits days between a Michigan office and a home in Indiana, reciprocity resolves the Michigan-worked days on the same terms, meaning Michigan still does not tax them.

Confirm with your employer that your payroll setup does not withhold Michigan tax if you keep an MI-W4 on file. If your payroll system withholds Michigan tax based on the employer's location, you will need to file MI-1040 with Schedule NR to reclaim it.

Mid-Year Move

What If I Moved Between Indiana and Michigan During the Year?

Reciprocity only helps for the parts of the year you were a resident of one of the reciprocal states and worked in the other. If you moved across the border during the year, file as a part-year resident in each state.

In Indiana, part-year residents and nonresidents use Form IT-40PNR instead of IT-40. Report only income earned during the Indiana residency period as Indiana resident income. Wages you earned in Michigan while an Indiana resident are still covered by reciprocity for that period.

In Michigan, part-year residents file MI-1040 with Schedule NR to allocate income between the resident and nonresident periods. Wages you earned in Michigan while a Michigan resident are taxed by Michigan on all sources, without a reciprocity carveout.

Document your exact move date. Utility activation records, lease or mortgage start dates, and driver's license updates serve as evidence. Both states may ask you to identify the residency change date because each state's tax claim depends on which days you were a resident.

Withholding Errors

What If My Michigan Employer Withheld Michigan Tax by Mistake?

Do not file a Michigan return under the reciprocity FAQ answer, because in this case you actually do need one to recover the money. Michigan's own guidance says to claim a refund of any Michigan withholding tax if you are a resident of a reciprocal state, you must file an MI-1040, Schedule 1, Schedule NR, and Schedule W.

Schedule NR allocates your income, your wages covered by reciprocity are not taxable to Michigan, and Schedule W reports the Michigan withholding so it comes back as a refund. Follow the MI-1040 instructions for where each figure goes.

For your Indiana return, still file IT-40 as a full-year resident and report the same Michigan wages. You do not claim credit on Schedule 6 for the mistakenly withheld Michigan tax, since reciprocity removes the Michigan tax obligation entirely and the money is being refunded by Michigan. Fix the underlying payroll issue by filing a fresh MI-W4 with your employer so future paychecks stop withholding Michigan tax.

City income tax

Do Michigan city income taxes apply to Indiana residents?

They can, and reciprocity does not help: Michigan's reciprocal agreements do not apply to local taxes. Twenty-four Michigan cities levy an income tax, and several tax nonresidents who work there. Detroit is the best-documented example:

• Nonresidents pay 1.2% (residents 2.4%) on wages for work in Detroit.
• Employers withhold Detroit tax from a nonresident only if Detroit is the predominant place of employment.
• Each exemption is worth $600 a year, and a nonresident who earns Detroit income must still file a Detroit return.

Indiana then gives a credit, but only against county tax. Schedule 6, line 1 of the IT-40 covers tax paid to another city, county or other local government. The credit is the smallest of three amounts: the local tax you paid, the income taxed by that locality multiplied by your Indiana county rate, and the county tax on your IT-40. The other-state credit on line 5 does not cover it. If you work in one of the other taxing cities, check that city's nonresident rate and return before you file.
