I live in MN and e-filed but it told me I have to send in my renters rebate though the mail. Why?
Form M1PR is filed separately from your Minnesota State Tax Return and isn't due until the August 15th. You may file Form M1PR and claim a refund for up to one year after the original due date. If you file later, you won’t receive a refund. The Minnesota Department of Revenue does not accept this form electronically - you will have to file by mail per their instructions.
