IFTA (International Fuel Tax Agreement) is a fuel tax reporting system for interstate trucking. Trucking companies report miles and fuel by state and file quarterly. Required for vehicles 26,001+ lbs or 3+ axles.
Quick Answer
IFTA is the International Fuel Tax Agreement. It lets interstate truckers file one quarterly fuel tax return with their base state instead of buying fuel permits in every state they travel through. Applies to vehicles over 26,000 lbs GVWR or GCWR.
Who Needs IFTA
Commercial vehicles with a gross vehicle weight or gross combination weight of 26,001 lbs or more that travel in two or more IFTA member jurisdictions. Most interstate trucking operations need IFTA. Intrastate-only carriers may not.
IFTA vs. IRP
IFTA covers fuel taxes. IRP (International Registration Plan) covers vehicle registration and license plates for apportioned vehicles. Both apply to interstate commercial carriers.
How IFTA Works
You register for IFTA with your base state (where your vehicles are registered). You receive IFTA decals and a license. Each quarter you report miles traveled and fuel purchased in each jurisdiction. Your base state calculates tax owed or refund due and distributes funds to other states. Filing is typically due by the last day of the month following each quarter (April 30, July 31, October 31, January 31).
IFTA and Truck Financing
IFTA registration is a regulatory requirement for interstate trucking–it does not directly affect financing approval. Lenders may verify that you have proper authority (DOT, MC, IFTA) when financing trucks for freight hauling. See What is DOT Registration and What is MC Number.
