What crossing the line costs
agreementMichigan does not tax you at all — the two states have an agreement, and you file a certificate with your employer. Solid is what you actually pay; the faded part of the Illinois bar is the credit it hands back. State income tax only — federal and payroll tax apply on top, and a city wage tax may too.
Which state taxes you, and what it costs
- Working in Michigan while living in Illinois is simpler than most border crossings. The two states agreed years ago to leave each other's residents alone on wages. Only Illinois taxes you, at $2,825 a year. File the non-residence certificate with your employer, named beside this page, and that is the end of it.
- This is not one of the country's big crossings. 7,438 jobs in Michigan are held by people living in Illinois. The tax rules do not care about that — they are the same ones that apply to the busiest routes in the country. What can differ is how used to the paperwork your employer is.
- Illinois and Michigan hold a reciprocity agreement covering wages, so Michigan does not tax this commuter at all and no resident credit is needed. The commuter files the work state's non-residence certificate with the employer — it is named in the panel beside this page — which stops Michigan withholding at source, and owes Illinois alone — $2,825 at the reference salary, identical to an earner who never crosses the line. ⚠️ The agreement covers WAGES. Other income sourced to Michigan is outside it, and an employee who does not file the certificate has Michigan tax withheld and must reclaim it on a non-resident return.
- This is a smaller corridor by national standards — 7,438 jobs in Michigan held by Illinois residents — but the rules that govern it are the same rules that govern the largest ones. Corridor size changes how familiar an employer's payroll department is with the paperwork, never the tax treatment.

What this page does not cover
- What you see here is state tax between Illinois and Michigan. Cities can charge their own tax on top, and a handful do. That layer is not modeled on this page, so treat these figures as the floor rather than the final bill.
- The figures take the simple case: one job, in Michigan, worked in person. Money from several states makes the credit a proportion instead of a cap. Working remotely from Illinois can pull you under a different rule entirely, depending on the state.
- Every dollar figure here uses a salary of sixty thousand a year. It is a stated benchmark, not a guess at what people on this route earn. Scale them to your own pay. Which state ends up dearer, Illinois or Michigan, generally holds at other salaries — though the gap between them can widen or narrow as you cross tax brackets.
- These figures cover the STATE layer only. City and municipal wage taxes sit on top of them and are not included: a commuter into Philadelphia pays its wage tax on top of anything here, and Ohio's municipalities run their own credit system, which this site models in its own families. New York City, by contrast, taxes only its residents, so a commuter into it adds nothing at the city level. Whether Michigan or Illinois carries a local layer is a separate question from the state arithmetic above.
- The arithmetic assumes all wages are earned in Michigan and that there is no other income. That matters for the credit: where income comes from several states, Illinois limits the credit to the share of its own tax attributable to the Michigan portion, computed as a ratio rather than the straightforward cap used above. It also assumes days are worked in Michigan rather than remotely — several states tax a non-resident's remote days as though they were worked at the employer's location, which reverses the usual expectation and is handled on this site's reciprocity pages.
- Dollar amounts are computed at a stated reference salary of sixty thousand rather than a corridor wage average, which no published source provides per state pair. Because both states' liabilities and the credit between them are functions of the same income, the direction of the Illinois to Michigan comparison holds at other salaries even though the amounts do not — with one qualification worth stating, that a progressive schedule can change the SIZE of the gap at higher incomes, and in Michigan's case a bracket crossed on one side and not the other is exactly where that happens.
Questions people ask
Do I pay state tax twice, to Illinois and Michigan?
Not twice over. Both states have a claim — Michigan because you earn the money there, Illinois because you live there — but Illinois gives you credit for what Michigan took. The credit stops at what Illinois would have charged on its own, so what you actually pay is the bigger of the two bills. Here that comes to $2,825 for the year.
Does working in Michigan cost me anything extra?
It costs you nothing in tax. $2,825 is what you owe whether you work in Michigan or at home in Illinois. The only real cost of the crossing is the extra return.
What do I give my employer so Michigan stops taking tax?
A single form, filed with your employer rather than with either state. It tells them you live in Illinois and that Michigan has agreed not to tax you, so they stop withholding Michigan tax from your pay. Without it the money comes out all year and you have to claim it back on a return you would not otherwise file.
Do I have to file tax returns in both Illinois and Michigan?
Two returns is the normal outcome here, even when only one state ends up taking anything. Michigan generally wants to see a non-resident return from people who work there, and Illinois wants your whole picture. It is paperwork rather than extra tax.
What if I work from home in Illinois some days instead of going to Michigan?
Working from home usually moves that day's pay out of Michigan and into Illinois alone. A handful of states disagree and tax remote days as if you had commuted. This page assumes you actually travel to Michigan, so if a lot of your week is at home the split will differ from what you see here.
How is liability allocated between residence and work state on the same wages?
Both jurisdictions assert a claim on the same wages — Michigan on a source basis, Illinois on residence. The residence state grants a credit for tax paid to the source state, limited to the residence state's own liability on that income. Net combined liability therefore equals the greater of the two liabilities rather than their sum, $2,825 at the reference salary, and the split between the two treasuries is the only thing the credit changes.
Why is the marginal state-tax cost of this crossing zero?
Marginal cost is zero because the binding liability is the residence state's. Illinois's own charge on this income equals or exceeds Michigan's, so the resident credit absorbs the source-state tax entirely and combined liability equals residence-only liability, $2,825. ⚠️ Zero marginal tax is not zero obligation: a non-resident return may still be required in Michigan.
What administrative step gives effect to the reciprocity exemption?
The exemption is self-executing only on filing: the employee furnishes the work state's non-residence certificate to the employer, which relieves the employer of the obligation to withhold Michigan tax. Absent the certificate the employer withholds, and the employee recovers the amount by filing a Michigan non-resident return — the liability position is identical, the cash-flow position is not.
What filing obligations arise in each state on this corridor?
Generally two. Illinois requires a resident return reporting all income; Michigan requires a non-resident return reporting the income sourced to it, which is also the mechanism by which the resident credit is substantiated. ⚠️ A filing obligation is distinct from a liability: a reciprocity exemption or a zero net position removes tax without necessarily removing the return, and the non-resident return is frequently what establishes the credit claimed on the resident one.
How do remote working days affect sourcing between these two states?
Ordinarily wages are sourced to where the services are performed, so days worked remotely from Illinois fall outside Michigan's jurisdiction and the source-state apportionment shrinks accordingly. ⛔ The exception is the "convenience of the employer" rule, which several states apply: a non-resident's remote days are sourced to the employer's location unless the remote work is required by the employer rather than chosen by the employee. The figures on this page model in-person attendance in Michigan throughout.
