The Q2 2026 IFTA filing season is now underway. Motor carriers operating in multiple IFTA jurisdictions must report their mileage and fuel purchases for the period April 1 through June 30, 2026, and file their quarterly return by July 31, 2026.

How These Changes May Affect Your Fleet

Even small tax rate adjustments can impact your quarterly IFTA calculations, especially if your fleet logs substantial mileage in affected jurisdictions.

Before filing your Q2 return, be sure to:

• Review your jurisdiction-wise mileage.
• Verify all fuel purchase receipts.
• Use the updated Q2 fuel tax rates.
• Double-check fuel type classifications.
• Keep supporting records in case of an audit.

Using outdated rates can lead to incorrect tax calculations and may require amendments later. Reliable IFTA reporting software updates tax rates automatically for every jurisdiction, so your calculations always reflect the current quarter.

Filing Tips for Your Q2 2026 IFTA Return

Accurate recordkeeping and timely preparation can help simplify your Q2 IFTA filing, reduce errors, and support compliance. Keep these best practices in mind before you file: 

1. Track Mileage by Jurisdiction

Maintain accurate records of the miles traveled in each IFTA member jurisdiction throughout the quarter. Using GPS-based mileage tracking or electronic logging devices (ELDs) can simplify recordkeeping and improve accuracy.

2. Keep Fuel Purchase Receipts Organized

Retain all fuel receipts and invoices, ensuring they include the purchase date, seller information, fuel type, number of gallons or liters purchased, and the jurisdiction where the purchase was made. Organized fuel records make reconciliation much easier.

3. Match Fuel Purchases to the Correct Jurisdiction

Verify that each fuel purchase is reported under the jurisdiction where it actually occurred. Incorrect jurisdiction reporting can result in inaccurate tax calculations and potential audit issues.

4. Review the Updated Q2 2026 Fuel Tax Rates

Although most jurisdictions maintained the same tax rates this quarter, Florida, Georgia, Indiana, Massachusetts, and New York introduced rate changes. Confirm that your calculations use the updated Q2 rates before filing.

5. Verify Your Total Mileage and Fuel Records

Before submitting your return, reconcile your trip mileage, odometer readings, and fuel purchase records. Reviewing these records together helps identify missing trips, duplicate entries, or reporting discrepancies.

6. Retain Supporting Documentation

Keep copies of your mileage reports, fuel receipts, trip sheets, invoices, and filed IFTA returns. These records should be readily available in case of an audit or future reference.

Penalties for Missing the Q2 IFTA Deadline

Filing after July 31, 2026 comes with real costs:

• A penalty of $50 or 10% of the total tax due, whichever is greater
• Interest charges on any unpaid tax balance
• Possible suspension of your IFTA license for repeated late filing
