Minnesota IFTA Compliance and Reporting Guide

The International Fuel Tax Agreement (IFTA) simplifies fuel use tax reporting for Minnesota-based motor carriers operating in multiple jurisdictions. Under Minnesota Statutes Chapter 296A, any carrier based in the state that operates a qualified motor vehicle across state lines must register with the Minnesota Department of Revenue (MNDOR). A qualified motor vehicle is defined as having two axles and a gross vehicle weight (GVW) or registered GVW exceeding 26,000 pounds, having three or more axles regardless of weight, or being used in a combination with a GVW exceeding 26,000 pounds. Carriers failing to comply face penalties, interest, and the potential revocation of their operating credentials. Maintaining precise mileage and fuel purchase records is the cornerstone of IFTA compliance. To simplify this process, DispatchTool provides integrated IFTA reporting that automatically aggregates GPS-validated mileage by state and matches it against uploaded fuel receipts. This functionality reduces manual entry errors and ensures that the total miles reported to the Minnesota Department of Revenue align with actual vehicle movements. Carriers can generate ready-to-file summaries within the platform to meet quarterly deadlines. Create a DispatchTool account to automate your mileage tracking and fuel tax preparation.

Registration and Licensing Fees

To obtain a Minnesota IFTA license, carriers must submit Form IG255, the IFTA Application. The Minnesota Department of Revenue does not charge a fee for the annual IFTA license itself; however, there is a $12.00 fee for each pair of IFTA decals. Every qualified vehicle must display two decals, one on each side of the exterior of the cab. Licenses are valid for one calendar year, expiring on December 31. Carriers are granted a grace period until the end of February to display new decals, provided they have a valid license for the current year. Applications can be processed online through the e-Services portal for faster turnaround compared to paper submissions.

Quarterly Filing Deadlines and Penalties

Minnesota requires IFTA returns to be filed on a quarterly basis. The deadlines are April 30 (Q1), July 31 (Q2), October 31 (Q3), and January 31 (Q4). If the deadline falls on a weekend or legal holiday, the return is due the next business day. Failure to file by the deadline results in a penalty of $50.00 or 10% of the tax due, whichever is greater. Interest is calculated at a rate of 0.42% per month (5% annually for 2024) on any unpaid tax. Even if no operations were conducted during a quarter, a 'No Operation' return must still be filed to maintain the license in good standing.

Recordkeeping Requirements under MN Statutes

The Minnesota Department of Revenue mandates that carriers retain records for four years from the filing date or the due date of the return, whichever is later. These records must include Individual Vehicle Mileage Records (IVMR) showing the date of trip, trip origin and destination, routes of travel, beginning and ending odometer readings, and total distance traveled in each jurisdiction. Fuel records must include original receipts or invoices showing the date of purchase, seller's name and address, number of gallons purchased, fuel type, and the price per gallon. Invoices must also clearly identify the vehicle that received the fuel via plate number or unit ID.

Minnesota Fuel Tax Rates

As of 2024, the Minnesota tax rate for both gasoline and undyed diesel is $0.285 per gallon. This rate includes a $0.25 per gallon excise tax and a $0.035 per gallon debt service surcharge. Carriers are credited for the tax paid at the pump in Minnesota against their total IFTA liability. Because fuel tax rates vary significantly in neighboring states—such as Iowa at $0.325 for diesel and Wisconsin at $0.329—accurate mileage reporting is essential to ensure tax credits are applied correctly. Underpayments to higher-tax jurisdictions result in additional liabilities during the quarterly reconciliation process.

Electronic Filing via MNDOR e-Services

Minnesota encourages all motor carriers to use the MNDOR e-Services system for filing Form IG254 (IFTA Quarterly Fuel Tax Return). The electronic system automatically calculates the tax or credit due for each jurisdiction based on the total miles and total gallons entered by the user. Payment can be made via Electronic Funds Transfer (EFT) or credit card. Carriers must ensure that 'Total IFTA Miles' matches the sum of miles in all individual jurisdictions, including non-IFTA provinces or states. The system provides an immediate confirmation number, which serves as legal proof of filing in the event of an audit.

Audit Selection and Procedures

Minnesota is required to audit 3% of its IFTA licensees annually to ensure compliance with the agreement. Audits typically cover the most recent 12 quarters. If an audit reveals that records are inadequate, the auditor may apply a standard assessment of 4.0 miles per gallon (MPG) to determine fuel consumption, which often results in a significantly higher tax liability than actual operations would dictate. Carriers receive a written notice at least 30 days prior to the start of an audit. Maintaining organized, digital records is the best defense against unfavorable audit findings and the associated interest penalties.

Frequently asked

What vehicles are exempt from IFTA in Minnesota?

Vehicles owned by the United States government, the State of Minnesota, or its political subdivisions are exempt. Additionally, recreational vehicles used strictly for personal pleasure and certain farm-registered vehicles operating within specific mileage radii may be exempt from quarterly filing requirements.

How do I get a temporary IFTA permit in Minnesota?

If you are not registered for IFTA but need to travel through Minnesota, you must purchase a 72-hour trip permit for $25.00. This permit allows a single vehicle to operate within the state for three days without a standard IFTA license and decals.

What is the penalty for not displaying IFTA decals in Minnesota?

Operating a qualified motor vehicle without valid IFTA decals or a temporary permit can result in a citation and a fine typically ranging from $100 to $500 depending on prior offenses. The vehicle may also be placed out of service until a valid trip permit is obtained.

Can I claim a refund for fuel used in PTO equipment?

Yes, Minnesota allows for a refund of tax paid on fuel used for non-highway purposes, such as Power Take-Off (PTO) units that operate reefers or pumping equipment. You must maintain separate records or use an agency-approved percentage to calculate the non-taxable fuel portion for Form GUR, the Gasoline User Tax Refund.
