What Is IFTA? Complete Guide for Owner Operators

IFTA stands for the International Fuel Tax Agreement. It is an agreement between U.S. states and Canadian provinces that simplifies fuel tax reporting for commercial motor carriers that travel in multiple jurisdictions.

Instead of filing separate fuel tax reports for every state, truck drivers and trucking companies file a single quarterly IFTA report through their base jurisdiction.

Before IFTA, interstate carriers had to file fuel tax reports separately in every state they traveled through. This process was time-consuming and created unnecessary paperwork.

IFTA was created to simplify reporting and ensure fuel taxes are distributed fairly among states based on where miles are driven.

Generally, IFTA applies to commercial vehicles that:

• Have two axles and a gross vehicle weight over 26,000 pounds
• Have three or more axles regardless of weight
• Operate in more than one state or province

Always verify requirements with your state transportation agency.

Drivers must keep accurate records of:

Miles Driven by State

Every mile traveled must be assigned to the state where it occurred.

Fuel Purchased by State

Drivers must maintain fuel receipts showing:

• Date
• Location
• Number of gallons purchased
• Price paid

A basic IFTA calculation uses:

• Total miles driven
• Total fuel purchased
• Average MPG
• Miles driven in each state

States then determine whether additional fuel tax is owed or whether a credit is due.

Many drivers make mistakes by:

• Losing fuel receipts
• Using incomplete mileage records
• Waiting until quarter-end to organize data
• Relying on memory instead of written records

Many owner-operators still use paper logs, clipboards, and spreadsheets.
