The primary multi-state tax filing for trucking is IFTA. The International Fuel Tax Agreement requires you to report fuel purchases and miles driven in each jurisdiction, then pay or receive credits based on where you actually burned fuel versus where you bought it.

You register for IFTA through your base state. For trucking companies in Northwest Arkansas, that means registering with Arkansas. Registration gives you decals and a license that let you operate across all member jurisdictions without buying separate fuel tax permits for each state.

Every quarter, you file a single IFTA return with Arkansas. On that return, you report total miles driven and fuel purchased, broken down by state. The report calculates whether you owe additional tax to states where you drove more than your fuel purchases would cover, or whether you get credits back from states where you bought more fuel than you used.

The critical part is tracking. You need accurate records of every mile driven in every state and every gallon purchased with location and date. GPS systems and fleet cards make this easier, but the data still needs to get into your books correctly. If you’re audited, IFTA auditors will want to see trip reports, fuel receipts, and logs going back four years.

Beyond IFTA, you’ll deal with IRP for apportioned registration. The International Registration Plan lets you pay registration fees proportionally based on miles driven in each state rather than buying separate plates everywhere. This isn’t a tax filing exactly, but it’s another multi-state compliance requirement that uses similar mileage data.

Some states also have weight-distance taxes or highway use taxes on top of IFTA fuel taxes. New York, Kentucky, Oregon, and New Mexico have additional requirements. If your routes include these states regularly, you need to track and file those separately.

The quarterly IFTA deadlines are the last day of the month following the quarter. January 31, April 30, July 31, and October 31. Miss a deadline and you’re looking at penalties and interest, plus potential issues with your IFTA license that can affect your ability to operate.

Having a bookkeeper near Rogers who understands trucking helps because the mileage and fuel data flowing through your books needs to match what you report to IFTA. When your bookkeeping and compliance filings are aligned, audits go smoothly and you catch discrepancies before they become expensive problems.
