IFTA Quarterly Filing Without the Stress

The International Fuel Tax Agreement (IFTA) requires motor carriers operating in two or more member jurisdictions to file quarterly fuel tax returns. These returns reconcile the fuel taxes you've paid at the pump with the taxes you owe based on miles driven in each state or province.

IFTA filing involves tracking every mile driven and every gallon of fuel purchased across all jurisdictions, calculating the net tax owed or refund due for each jurisdiction, and submitting accurate returns by the quarterly deadlines: April 30, July 31, October 31, and January 31.

Mistakes in IFTA filing can trigger audits that go back four years, and penalties for late or inaccurate filings range from $50 to $500 per quarter, plus interest on any underpaid taxes. For carriers operating across many states, the complexity multiplies with each jurisdiction.

The most common IFTA filing errors we see from carriers trying to file on their own include miscalculating jurisdictional miles, failing to account for deadhead miles, using incorrect fuel tax rates (which change quarterly), and missing filing deadlines. Each of these mistakes can trigger penalties, audits, or both.

Our team stays current on every jurisdictional fuel tax rate change, knows the rules for calculating miles in each state, and has systems in place to ensure no deadline is ever missed. We've filed thousands of IFTA returns with a 100% accuracy rate.
