You probably have at least some sort of familiarity with the International Fuel Tax Agreement, more commonly known as IFTA. If you’re the one responsible for filing each quarter, you might hear the word “IFTA” and start feeling a sense of dread.

IFTA reporting is a necessary, often time-consuming exercise that carriers in the lower 48 states and 10 Canadian provinces have to perform four times each year and is a necessary part of the transportation industry. Rather than reporting fuel taxes in each state individually, IFTA allows carriers to report and pay fuel taxes in their base state of operations. 

While IFTA reporting likely isn’t anyone’s favorite thing to do, it’s a much more streamlined method for drivers and fleet owners to pay their taxes. There are some common mistakes that people make during the reporting process, though. Below, we’ll go over some of those mistakes, the consequences of missing and/or failing to file IFTA and how to make the process easier.  

5 Common IFTA Reporting Mistakes

There are a handful different of reasons why IFTA reporting mistakes can happen. These errors can be corrected, but filing with errors or consistently filing amended reports may eventually result in an audit. Here are some common mistakes to watch for to help you avoid potential consequences.

Missing deadlines/failing to file

The vast majority of people who fail to file on time don’t have any ill intent. The reality is that IFTA deadlines sneak up and people are busy with day-to-day tasks. Still, with a quarterly deadline, it’s imperative that those responsible for filing memorize the following dates: 

  • January – March (April 30)
  • April – June (July 31)
  • July – September (October 31)
  • October – December (January 31) 

Estimating in their reports 

It’s easy to think that estimating your average miles per gallon or your miles traveled is harmless, especially with how time-consuming IFTA reporting can be. However, estimating your IFTA fuel calculations could lead not only to possible consequences, but also potentially cause you to miss out on refunds or tax credits.

Omitted information

Another common mistake people make is failing to include certain pieces of important information. Oftentimes, this includes things like not counting empty miles or failing to account for miles where a driver was running personal errands (such as picking up food). It can also stem from failing to report problems with your GPS or odometer, which can lead to penalties due to misreported numbers. 


It’s important to maintain and, ideally, organize all records needed for proper IFTA reporting. Missing records, or records that are unreadable, may lead to inaccurate reporting that can either lead to an audit, or force you to amend a return. 

Waiting until the last minute 

Procrastination increases the probability of making mistakes. While it’s tempting to put this type of work on the backburner as long as possible, doing so might set you up for failure. 

What can happen if you don't file IFTA or file incorrectly?

As we mentioned, missing IFTA reporting deadlines, filing your IFTA reports incorrectly or failing to pay for any penalties can lead to consequences that range in severity. 

The harshest of these is the suspension of your IFTA license, which can occur if you fail to submit your report each quarter. This type of penalty can impact your business multiple ways, including penalties, accrued interest fees, paying to get re-instated and any potential impact on your business reputation.  

The penalties aren’t as harsh if you file late but they can still be impactful. Most states have a flat rate penalty of either $50 or 10 percent of the taxes due, depending on which is greater. Within the lower 48 states, the only exception is Nevada, which offers a harsher penalty of $50 and 10 percent of the taxes due. Any late payments for these penalties are also subject to accruing interest fees that may vary by state.

IFTA audits aren’t necessarily common, and about three percent of trucking companies will receive one each year regardless of whether or not they file properly. However, things like multiple amended reports or consistently filing your returns late can potentially trigger an audit. Though it’s unlikely that your company would be shut down completely in the event of a failed audit, you will be subject to possible penalties.
