IFTA filing is one of the most confusing administrative requirements for owner operators but it is absolutely mandatory for anyone operating a commercial vehicle across state lines. Here is your complete guide to IFTA filing in 2026. What is IFTA — The International Fuel Tax Agreement is a cooperative agreement between the 48 contiguous US states and 10 Canadian provinces that simplifies fuel tax reporting for interstate carriers. Instead of filing fuel taxes in every state you operate in you file a single quarterly report with your base state. Who Needs IFTA — Any commercial motor vehicle with two axles and a gross vehicle weight over 26,000 pounds or with three or more axles regardless of weight that operates in two or more IFTA jurisdictions must register. How to Register — Apply for your IFTA license through your base state’s transportation or revenue department. You will receive an IFTA license and two decals that must be displayed on your truck. What to Track — You must track all miles driven in each jurisdiction and all fuel purchased in each jurisdiction every quarter. Accurate record keeping is essential. How to File — Submit your IFTA return quarterly by the last day of the month following the end of the quarter. January 31, April 30, July 31, and October 31 are the standard deadlines. Common Mistakes — Inaccurate mileage records, missing fuel receipts, and late filings are the most common IFTA mistakes. All of these result in penalties and interest charges.
