Understanding IFTA Miles and Fuel Costs

For anyone running a trucking business or managing a fleet, understanding your IFTA miles and diesel fuel costs is key to keeping expenses under control. IFTA (International Fuel Tax Agreement) requires carriers to track the miles driven and fuel purchased in each state. These numbers are then used to calculate your IFTA fuel tax for each quarterly report.

It’s easy to think the cheapest pump price automatically means the best deal, but under IFTA, that’s not always true. A state with a higher pump price but a higher tax rate can actually end up being cheaper overall once the IFTA credits and debits are applied. By comparing diesel prices and IFTA tax rates in each state, truck drivers and fleet owners can make smarter fueling decisions, improve IFTA compliance, and save money over time.

If you want to simplify this process, using an IFTA calculator or a fuel tracking app can help you see the true cost per gallon in real time and keep your IFTA reporting accurate each quarter. Knowing how IFTA impacts your fuel costs is one of the easiest ways to increase profitability and keep your trucking business running efficiently.
