5 Common Mistakes on IFTA Quarterly Returns

From missing receipts to mismatched odometer readings, these are the errors that trigger audits and penalties — and how to avoid them.

IFTA audits are rising across most Canadian provinces. The good news: most findings come from the same handful of mistakes.

1. Missing fuel receipts Every gallon claimed needs supporting documentation. Card statements alone don't cut it.

2. Odometer gaps Your distance per jurisdiction has to reconcile to your total odometer reading. Gaps trigger questions.

3. Personal use mileage Yes, personal-conveyance miles still count for IFTA. They have to be reported.

4. Wrong fuel type Reefer fuel, bulk fuel, and on-road diesel are not interchangeable on a return.

5. Late filing Even a zero return has to be filed on time. Penalties stack quickly.
