Out-of-state students attending a Michigan college or university are considered nonresidents. You may be required to file a nonresident state return.
If your federal adjusted gross income is over $4,050 then you are required to file a nonresident Michigan state return. However, the filing requirement is different if you were claimed as a dependent. In that case, you are required to file if your federal adjusted gross income is over $1,500 (single or married filing separately) or over $3,000 if filing
a married filing joint return.
Even if you are not required to file you may want to in order to claim a refund of tax withheld. Follow the directions in the TurboTax FAQ below if you need to prepare a nonresident state return.
