Michigan IFTA Reporting Requirements

Michigan IFTA at a glance

Michigan's current diesel fuel tax rate is $0.507/gallon, and the jurisdiction requires electronic filing of quarterly IFTA returns. You file directly with the state agency at the official Michigan IFTA portal.

Michigan follows the standard IFTA quarterly deadlines: April 30 for Q1, July 31 for Q2, October 31 for Q3, and January 31 for Q4 (filing for the prior calendar quarter). Late filing typically triggers a penalty of the greater of $50 or 10% of net tax liability, plus interest accrued from the original due date.

What to know about IFTA in Michigan

Michigan's $0.507/gallon diesel tax is above the IFTA average, funding road maintenance for a state that experiences some of the harshest winter freeze-thaw cycles in North America. Michigan is the auto manufacturing capital of the U.S. and a critical IFTA state for automotive freight moving between Detroit, Chicago, Toronto, and points east.

IFTA returns are filed electronically through the Michigan Treasury Department at michigan.gov/IFTA. New carriers apply through Michigan eServices; the decals are mailed for the calendar year. Standard quarterly deadlines (April 30, July 31, October 31, January 31) apply.

Michigan-based carriers running across the Canadian border into Ontario should track miles carefully — short-distance border crossings at Detroit-Windsor, Port Huron-Sarnia, and Sault Ste. Marie are common but often under-reported. Michigan auditors look specifically at trips that should show Ontario miles but report none. Carriers should also reconcile cardlock fuel purchases in Michigan against pump receipts; Michigan's rate is high enough that cardlock-only buying can result in significant overpayment claims that auditors will scrutinize closely.

Who needs a Michigan IFTA license?

You need a Michigan IFTA license if you operate in Michigan and at least one other IFTA jurisdiction with vehicles that are:

• Three or more axles (any weight)
• Over 26,000 lbs. gross or registered weight
• Combined weight over 26,000 lbs.

Your IFTA license and decals are issued by your base jurisdiction — for Michigan-based carriers, that means filing with the state revenue or transportation department listed above. All quarterly returns flow through that single base-jurisdiction filing, even when miles were driven across multiple states or provinces.

Who needs to file Michigan IFTA taxes?

All license holders must file quarterly IFTA tax returns, even if no miles were traveled.

Note: Licenses remain active until officially closed.

What happens if you file IFTA incorrectly?

What are you risking by submitting an inaccurate IFTA filing? Even small discrepancies in reported miles or fuel can lead to:

• Costly fines and back taxes
• Delays with renewals or suspended accounts
• Failed audits and penalties

Why do errors happen?

• Mileage and fuel data accumulate quickly — it’s tough to catch every issue. Records often go unnoticed until it’s too late.
• Carriers often depend entirely on ELD IFTA reports, thinking they’re complete — but there’s no way to verify them.
• Fuel card reports may exclude cash purchases or missing transactions.
