Missouri IFTA Reporting Requirements

Who needs a Missouri IFTA license?

You need an IFTA license if you operate in Missouri and at least one other 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.

Who needs to file Missouri 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.
