“Forms go out to libraries, etc. after the ones that are sent directly to the taxpayers have a chance to arrive – otherwise there would be a huge paper waste."
The MI-1040, MI-1040CR-2, MI-1040CR-5 and MI-1040CR-7 instruction booklets will be mailed to taxpayers who paper filed their 2017 return on Michigan Department of Treasury forms. Taxpayers who e-filed or had a tax preparer complete their forms will not be mailed a booklet.
Forms and instructions may be viewed and/or downloaded from our Web site beginning in January 2019. In addition, commonly used forms will continue to be available at Michigan Department of Treasury offices, most public libraries, Northern Michigan post offices, and Michigan Department of Health and Human Services (MDHHS) county offices.
Note: Bulk forms are distributed to libraries and post offices throughout the state before they are available in Michigan Department of Treasury offices. Therefore forms may not be requested through the Michigan Department of Treasury Customer Contact Center until mid-February.
