A comprehensive guide to Michigan's withholding rules, reciprocal state agreements, and how work location — not employer location — determines tax obligations for Michigan Tech employees.
Last updated: April 2026 | Source: Michigan Department of Treasury
Important Principle
Michigan tax withholding is determined by where the employee physically performs their work, not by where Michigan Tech is located. The employer's location in Michigan does not automatically create a Michigan withholding obligation for out-of-state remote workers.
Foundation
The Core Withholding Rule
A nonresident employee is taxed only on compensation for services physically performed within Michigan. A Michigan employer must withhold Michigan income tax only for compensation earned by a nonresident while working in Michigan. Where the employer is headquartered is irrelevant.
This means that if an MTU employee lives and works fully remotely in another state and never sets foot on the Houghton campus to perform work, Michigan income tax withholding is generally not required on those wages — regardless of the fact that MTU is a Michigan institution.
What About the "Benefit to MTU" Argument?
A concept called the "Convenience of the Employer" (COE) rule exists in some states, which argues that if remote work benefits the employer's home state, that state can claim taxing rights. However, Michigan has not adopted this rule. States that enforce COE include New York, Delaware, Pennsylvania, Nebraska, and Connecticut. Michigan follows the physical-presence standard only.
Reciprocal Agreements
Michigan's Reciprocal States
Michigan has formal reciprocal tax agreements with six neighboring states.
Under these agreements, employees who live in one of these states and work in Michigan only pay income tax to their home state, not Michigan, regardless of where the physical work is performed.
- Illinois
- Minnesota
- Indiana
- Ohio
- Kentucky
- Wisconsin
✓ Reciprocal State Employee
- Only home state taxes withheld
- No Michigan withholding—even if working on campus
- Employee files exemption form with MTU payroll
- Simpler compliance—one state only
✗ Non-Reciprocal State Employee
- Michigan taxes withheld for days worked in Michigan
- Work state taxes withheld for days worked remotely
- May require MTU to register as employer in that state
- More complex—potential two-state compliance
Does Reciprocity Still Apply if the Work Rule is Physical Location?
Yes, this is the key distinction. Reciprocal agreements are an exception to the physical-presence rule. Without reciprocity, a Wisconsin resident working on MTU's campus would owe Michigan tax (physical presence in MI) plus potentially Wisconsin tax (resident state). The reciprocal agreement eliminates the Michigan obligation entirely, keeping it simple: Wisconsin taxes only.
Specific Scenario
Wisconsin Resident Working on MTU Campus
Employee lives in Wisconsin but physically performs work on the MTU campus in Houghton
Without a reciprocal agreement, working in Michigan would trigger Michigan income tax withholding. However, Michigan and Wisconsin have a reciprocal agreement, which changes the answer entirely.
Answer: Wisconsin taxes only. Because Wisconsin is a reciprocal state, this employee is exempt from Michigan income tax withholding — even while physically working on campus. MTU should withhold Wisconsin income tax only. The employee must file a Michigan exemption certificate (MI-W4 with the nonresident exemption) with Payroll. No Michigan withholding applies.
Quick Reference
Withholding Scenarios At A Glance
Use the table below to quickly determine which state(s) require withholding based on where the employee lives, where the work is performed, and whether a reciprocal agreement applies.
| Employee Situation | MI Withholding | Other State | Notes |
|---|---|---|---|
| Lives and works fully remotely in a non-reciprocal state | No | Yes | Work-state taxes only; MTU may need to register in that state |
| Lives in a non-reciprocal state, splits remote and campus time |
Yes, Apportion |
Yes, Apportion |
MI for campus days; home state as resident; credit usually available, track days carefully |
| Lives in a reciprocal state (IL, IN, KY, MN, OH, WI), works on MTU campus | No | Yes (home state) | Reciprocal agreement overrides physical presence rule; employee files exemption form |
| Lives in a reciprocal state, works fully remotely in their state | No | Yes (home state) | Home state only; simplest scenario |
| Michigan resident, works fully on MTU campus | Yes | No | Standard single-state scenario |
| Michigan resident, temporarily working remotely in a non-reciprocal state | Yes | May Apply | MI taxes all resident income; work state may also require withholding; credit reduces double taxation |
Next Steps
What Employees and Departments Should Do
For Employees Working Outside Michigan
- Notify Payroll Services of your work location state
- If in a reciprocal state: complete a Michigan nonresident exemption form (MI-W4) and submit the work state's withholding form
- If in a non-reciprocal state: work with Payroll to set up withholding for that state; do not assume Michigan withholding covers your obligation
- Track days worked in Michigan vs. remotely if you split time between campus and home office
- Consult a personal tax advisor for filing guidance — MTU Payroll handles withholding but cannot provide individual tax advice
Updating Your State Tax Withholding
Michigan (MI-W4) — update through Experience self-service
To update your Michigan withholding, log in to Experience at https://experience.elluciancloud.com/mtu and navigate as follows:
- Payroll card
- Tax Forms
- Benefits Current Summary
- Benefits and Deductions
- Miscellaneous
- Update State of Michigan Income Tax
A couple of important notes about self-service:A couple of important notes about self-service:
- Michigan only. Self-service only updates the MI-W4. It cannot be used to set up withholding for any other state or to claim a reciprocal-state exemption.
- Future payrolls only. Updates apply to future pay periods and cannot be backdated.
Through self-service, your MI-W4 can be set to Active with personal/dependent exemptions, additional per-pay-period withholding, or both — or Inactive to claim exemption from Michigan withholding. If you live in a reciprocal state and want Michigan withholding stopped under that agreement, follow the non-Michigan instructions below.
Non-Michigan state W-4s — submit by email
State withholding certificates for any state other than Michigan — including the reciprocal-state W-4s used to claim a Michigan exemption (Illinois, Indiana, Kentucky, Minnesota, Ohio, Wisconsin) — cannot be entered through Experience self-service. To set up or update non-Michigan state withholding, email your completed form to payroll-help@mtu.edu.
Important — protect your personal information:
Our ticketing system is not as secure as Experience self-service. To protect your identity, do not include your Social Security Number on any form or email sent to payroll-help@mtu.edu. Instead, write your MTU M# in place of the SSN so Payroll Services can match the form to your record. We will add the SSN to your file through our secure systems on our end.
