on the 1040NR your wages are only US source for the days you physically work in the US. any days you end up working from the windsor side are canadian source and stay off the 1040NR. so you apportion by workday location, not by where the employer sits. it doesn't change your canadian tax since you're resident and taxed on worldwide anyway, but it shrinks the US side and keeps you from over withholding US tax you'd just have to claim back
Answered August 2026
For Michigan and Detroit income-tax purposes, you do not need a Detroit address, but Michigan tax should be withheld from the pay attributable to the days you physically work in Detroit—not from your Windsor workdays.
“I live in Windsor and work a hybrid job commuting to Detroit. Do I need to maintain a Detroit address and have Michigan state tax withheld from my payslip?”
Summary
You do not have to become a Detroit resident just because you commute there. The manageable part is to give payroll your true Windsor address, separate Detroit days from Windsor days, and reconcile any over-withholding on nonresident returns.
Your address answer is fixed, but the payroll result forks according to where you physically work and whether Detroit is your predominant work location.
Keep Windsor as your real addressno Detroit address
For Detroit tax, you are a because you are domiciled outside the city; you do not need to maintain a Detroit address. Give payroll your Windsor address and country code CA.
Michigan daysstate withholding
Michigan allocates a nonresident's pay to the state only to the extent it is for personal services performed in Michigan. Your employer should withhold Michigan tax from pay for your Detroit workdays; the 2026 withholding rate is 4.25% after applicable exemption allowances.
Windsor home-work daysoutside Michigan
Days when you physically perform the job from Windsor are not under MCL 206.110(2)(a), and they are also outside Detroit. Track these days so payroll or your annual nonresident returns can exclude them.
Detroit is predominantcity withholding
If payroll determines on Form 5527 that Detroit is your , Detroit withholding applies at 1.2% only to the estimated Detroit-work portion of your wages.
Detroit is not predominantfile and pay
Detroit payroll withholding is not required when Detroit is not your predominant place of employment, but you still owe Detroit nonresident tax on wages for the days actually worked in Detroit and reconcile that amount on Form 5119.
These routes address Michigan and Detroit income tax, not federal immigration status or a private employer's internal residency policy.

Watch out for
Canada is not a reciprocal stateDo not claim the reciprocal-state exemption on Form MI-W4. Michigan's 2026 guide lists only Illinois, Indiana, Kentucky, Minnesota, Ohio, and Wisconsin, so your Windsor residence does not remove Michigan withholding on .
State and city tax are separateMichigan withholding applies to pay for work done in Michigan. Detroit separately taxes pay for work done in the city at the nonresident rate; city payroll withholding depends on whether Detroit is your .
No city withholding can still mean city taxIf Detroit is not your predominant work location, payroll may not withhold Detroit tax, but MCL 141.613 still taxes compensation for services actually performed in Detroit. Keep money aside for the nonresident city return.
Do not let payroll treat you as a Detroit residentA Detroit is someone domiciled outside the city. Use your real Windsor address and Form 5527 (DW-4); a Detroit address could cause the wrong resident withholding rate to be used.
Correct excess withholding on the returnIf Michigan tax is withheld from your entire salary even though you work some days from Windsor, Schedule NR reports only wages earned in Michigan. File MI-1040 with Schedule NR to claim credit for the withholding and recover any overpayment.

These steps put the right address and work-location percentages into payroll, then preserve the proof needed to reconcile your taxes.
Now

Check both tax lines on each payslip
Michigan withholding should cover compensation for work done in Michigan at the 2026 rate of 4.25% after applicable exemption allowances. Detroit is a separate line: if Detroit is your predominant place of employment, withholding is 1.2% of Detroit wages only; if it is not predominant, city withholding may be zero even though city tax remains due on actual Detroit wages.

File nonresident returns to reconcile

MCL 141.613(a)
Detroit taxes a nonresident's compensation only for work actually done or services performed in Detroit.
MCL 141.613(a)
MCL 141.613(a)

page 1
Nonresidents of the City of Detroit are subject to withholding only if the City of Detroit is their predominant place of employment.

MCL 141.651(1)(b)
MCL 141.651(1)(b)
The withholding rate shall be applied to the percentage of the employee's total compensation equal to the employee's estimated percentage of work to be done or services to be performed in the city for that employer, but no withholding shall be required if the estimated percentage of work is less than 25%.
