Do I Have to File IFTA If I Only Have One Truck?

Yes. IFTA has nothing to do with how many trucks you have — it applies to qualified motor vehicles operated in more than one member jurisdiction. One truck crossing a state line puts you in it. One truck that never leaves your state does not.

You file even in a quarter you did not run

A zero-miles quarter still gets a return. A skipped return is a late return, not a non-existent one, and it is one of the easiest penalties in trucking to collect by accident.

What late actually costs

The late penalty is $50 or 10% of the net tax due, whichever is greater, plus interest per jurisdiction. Repeat lateness puts your IFTA license at risk of revocation, which is a bigger problem than any single penalty.

The decals are a separate deadline

Your IFTA license and decals expire December 31 every year. There is a grace period through the end of February, but only if your renewal is already in process — otherwise you are running on an expired credential, and that is out-of-service-able. Most base states open renewals in the fall.

What you actually have to track

Miles by state and fuel by state, for every quarter. That is the whole data requirement, and it is why people who do not track it as they go end up reconstructing a quarter from a shoebox of fuel receipts and a memory of where they went.

Two separate obligations catch people: Kentucky's KYU is filed outside the IFTA return, and Oregon's weight-mile tax report is filed in addition to any Oregon IFTA return.
