In 2015, you will no longer be able to file paper IFTA tax returns. This means that the IFTA tax return that is due on January 31, 2015 (which covers the October, November and December 2014 reporting period) MUST BE ELECTRONICALLY FILED using Michigan's new IFTA tax return processing system. For more information, see the Notices below:
Licensed IFTA carriers are required by the IFTA Agreement and Michigan Motor Carrier Statute to keep vehicle records for 4 years from the due date of the return or the date the return was filed, whichever is later. Although DOT/FMCSA only requires 6 months of record keeping, you must maintain your fuel and mileage records for IFTA and IRP purposes for a minimum of 4 years.
