The International Fuel Tax Agreement (IFTA) lets interstate carriers file one quarterly fuel-tax return instead of one per state. Get it wrong and you'll either overpay tax or trigger a state audit. We handle filings for fleets of every size.
How IFTA actually works
You pay diesel tax at the pump. IFTA reconciles what you paid versus what you owe each state based on miles driven there.
Drive more miles in a high-tax state than you bought fuel in? You owe that state. Bought a lot of fuel in a state you barely drove through? You're owed a refund.
Returns are due April 30, July 31, October 31 and January 31. Late filings trigger a $50 minimum penalty plus interest.
What we need from you
Total miles driven per state for the quarter (from ELD, trip sheets or IRP-style records).
Total fuel purchased per state (from fuel-card reports or receipts).
We do the rest — jurisdiction-by-jurisdiction calculation, return preparation, electronic filing and net-due payment instructions.
Records you must keep
IFTA requires four years of fuel and mileage records. We help you organize them in a way that survives a state IFTA audit — because auditors will ask.
Frequently asked questions
Who has to file IFTA?
Any qualified motor vehicle (CMV over 26,000 lbs GVWR or with three or more axles) that operates in two or more IFTA jurisdictions.
What if I forgot to track miles by state?
Call us before the deadline. We can often reconstruct from ELD data, toll records or fuel-card GPS pings — but it's far easier to track from day one.
What happens in an IFTA audit?
States audit roughly 3% of IFTA accounts per year. They'll ask for four years of mileage and fuel records. If your numbers don't reconcile, they'll re-assess and bill you.
