The 7 IFTA Filing Mistakes Owner-Operators Keep Making

Late penalties, missed jurisdictions, fuel receipts in the wrong column — the small stuff that quietly adds up at year-end.

Most owner-operators we work with come to us after their second or third IFTA quarter — usually because something didn't add up.

Here are the seven mistakes we see most often, and how to prevent each one before the next quarter closes.

1) Mileage records that don't survive an audit. The IFTA itself doesn't care how you track miles, but if you ever get audited, you need source records — not the summary you typed into a spreadsheet last Tuesday.

2) Treating fuel taxes as a write-off twice. Fuel tax credits from IFTA reconciliation can quietly get double-counted on the P&L. We see this in roughly 1 in 3 sets of books we clean up.

3) Missing a jurisdiction. If you drove through it, it goes on the return — even five miles in a corner of Indiana on your way through Chicago.

There are four more. We'll keep this list short — the point is that none of these are dramatic. They're small, quiet errors that compound over quarters.
