Are wages earned by a Michigan resident, who is telecommuting from a location in another state, subject to tax in Michigan?

Yes. Michigan residents owe tax on all income from wages, salary, or guaranteed payments, no matter where it is earned.

 A Michigan resident may qualify for a non-refundable tax credit for tax paid to another government unit outside of Michigan, including:

• A nonreciprocal state
• A local government unit outside Michigan, including tax paid to a city located in reciprocal states
• The District of Columbia
• A Canadian province

The credit for taxes paid to another state is not available for:

• Salaries and wages earned in a state that has a reciprocal agreement with Michigan or
• Earnings not included in your Michigan taxable income

If a Michigan resident erroneously had income tax withheld for a reciprocal state* on salaries and wages earned there, it is the Michigan resident's responsibility to file a nonresident tax return with that state to get a refund of the tax withheld in error.
 

* Illinois, Indiana, Kentucky, Minnesota, Ohio, and Wisconsin have reciprocal agreements with Michigan.
