5 common IFTA fuel tax reporting mistakes you must avoid

The process of filing IFTA fuel tax reports can be overwhelming and time-consuming. It becomes even more problematic and complex if simple mistakes are made.

For many fleets, IFTA fuel tax reporting can be an administrative burden, and they want to complete the reports correctly and efficiently. To help such fleets, we have put together a list of 5 common IFTA fuel tax reporting mistakes that must be avoided.

Mistake #1: Filing late

IFTA fuel tax reports are required to be filed four times a year. The deadlines, however, always seem to sneak up. It’s easy to get distracted or busy and forget about the upcoming deadline. That’s a mistake you must avoid.

Submitting your IFTA report late will lead you to a $50 penalty or 10% of the net tax liability, whichever is higher. It may also increase the chances of an audit.

Furthermore, if an auditor determines that you did not file the returns with an intent to commit fraud, you may be fined up to $5,000 and be subject to criminal prosecution.

Mistake #2: Making estimates

Since the process of IFTA fuel tax calculation can be very time-consuming and complex, it is tempting to just estimate the miles traveled and the fleet’s average MPG at the end of each quarter. However, it is important not to fall into that trap. You need to record all numbers accurately.

Incorrect fuel calculations may raise doubts and lead to an audit. You are required to maintain precise records — not estimates — of fuel use and mileage.

Mistake #3: Not recording personal miles

One common mistake that some fleet managers make is that they don’t log personal miles. If you don’t include personal miles — for example, miles recorded during a driver’s personal errand — you will have mileage gaps in your records.

Any discrepancy in records may raise red flags and lead to an audit.

Mistake #4: Not filing a return

What if your fleet did not operate during a quarter?

You’d still need to file the quarterly IFTA report. If you have an IFTA license, you are supposed to submit the quarterly IFTA reports even if your fleet didn’t operate during a quarter.

Mistake #5: Ignoring odometer issues

If there is an issue with the odometer, you are expected to address it. Issues with the odometer or GPS tracking can affect the reported numbers and skew them, which is why you must note any such incident.
