Submitting files

Michigan accepts Prior year filing.
If corrected forms need to be sent, simply remit them as you normally would. Treasury will use the most recent form received. See 1099 corrections as new original file.

After logging in to MTO

Select EFW2 Upload to submit the 1099s or W-2s

CFS does not support CD filing because Form 447 is not supported by CFS and the form is required to accompany the CD.
