Every return the department receives is different and processing time will vary. You can follow the status of your refund by using Minnesota's Where's My Refund? system.
If your return is incomplete or necessary information is not enclosed, your refund will be delayed or your return will be sent back to you.
It is very important that you email or call the department at email@example.com, 651-296-3781, or 1-800-652-9094 if you move from the address given on your Form M1PR before you receive your refund. If your refund check is not cashed within two years from the date it was issued, you may lose your right to the refund.
