Understanding IFTA (International Fuel Tax Agreement)

The International Fuel Tax Agreement (IFTA) is an agreement among U.S. states and Canadian provinces that simplifies the reporting of fuel use taxes by interstate motor carriers. Instead of filing separate fuel tax returns with each jurisdiction, IFTA allows carriers to file a single quarterly fuel tax return with their base jurisdiction.

Who Needs to File IFTA?

Generally, you need to file IFTA if you operate a qualified motor vehicle in two or more IFTA jurisdictions. A "qualified motor vehicle" is defined as a motor vehicle used, designed, or maintained for transportation of persons or property and:

• Has two axles and a gross vehicle weight or registered gross vehicle weight exceeding 26,000 pounds (11,797 kilograms); or
• Has three or more axles, regardless of weight; or
• Is used in combination with a trailer, and the combined gross vehicle weight or registered gross vehicle weight exceeds 26,000 pounds (11,797 kilograms).

Recreational vehicles are typically exempt from IFTA unless they are used in a business capacity.

How IFTA Works

IFTA is based on the principle of "pay where you burn." This means that fuel taxes are ultimately paid to the jurisdictions where the fuel is consumed, regardless of where it was purchased. Here's a simplified breakdown:

1. Track Miles: You track the total miles driven in each IFTA jurisdiction.
2. Track Fuel Purchases: You track all fuel purchased (and the jurisdiction where it was purchased).
3. Calculate Fuel Consumed: Using your vehicle's average fuel economy (MPG), the calculator determines how much fuel was consumed in each jurisdiction based on miles driven.
4. Determine Net Fuel: For each jurisdiction, the calculator subtracts the fuel purchased in that jurisdiction from the fuel consumed in that jurisdiction.
   • If Fuel Consumed > Fuel Purchased: You owe tax to that jurisdiction for the difference.
   • If Fuel Purchased > Fuel Consumed: You are due a refund from that jurisdiction for the difference.
5. Apply Tax Rates: The net fuel amount for each jurisdiction is multiplied by that jurisdiction's current fuel tax rate to determine the tax owed or refund due.
6. Total Net Tax/Refund: All individual jurisdiction taxes/refunds are summed up to give you a total net amount for your IFTA filing.

Using the IFTA Calculator

To use this calculator:

1. Average Fuel Economy (MPG): Enter your vehicle's average miles per gallon for the reporting period. This is crucial for accurate calculations.
2. Jurisdiction Data: For each jurisdiction you operated in:
   • Jurisdiction Name: (Optional, for your reference)
   • Miles Driven: Enter the total miles your qualified vehicle traveled within that specific jurisdiction.
   • Fuel Purchased (Gallons): Enter the total gallons of fuel purchased within that specific jurisdiction.
   • Fuel Tax Rate ($/Gallon): Enter the current IFTA fuel tax rate for that jurisdiction. These rates change quarterly, so ensure you have the most up-to-date figures from your state's IFTA agency or a reliable tax service.
3. Calculate IFTA: Click the "Calculate IFTA" button to see your estimated tax liability or refund.

Disclaimer: This calculator provides an estimate based on the data you input. Actual IFTA filings require precise record-keeping and adherence to specific jurisdictional rules. Always consult official IFTA resources or a tax professional for accurate filing.
