How to Set Up Your Missouri IFTA Account

To set up an International Fuel Tax Agreement (IFTA) account in Missouri, a carrier must be based in the state and operate a qualified motor vehicle in at least one other IFTA jurisdiction. A qualified motor vehicle is defined by the Missouri Department of Transportation (MoDOT) as having two axles and a gross vehicle weight exceeding 26,000 pounds, having three or more axles regardless of weight, or being used in combination where the total weight exceeds 26,000 pounds. Carriers must submit Form 4825, the IFTA Application, to the MoDOT Motor Carrier Services division to begin the process. Establishing an account requires a valid USDOT number and an active Federal Employer Identification Number (FEIN) or Social Security Number. Once registered, carriers receive one IFTA license and two decals per vehicle, which are valid for the calendar year. DispatchTool assists Missouri carriers in this process by automatically tracking GPS miles traveled in each state and calculating total fuel purchases by jurisdiction. This data can be exported to complete the MoDOT quarterly tax returns, ensuring that mileage on routes like I-70 or I-44 is accurately recorded without manual log entry. Create a DispatchTool account to automate your mileage data collection for upcoming quarterly filings.

Determining Base Jurisdiction Eligibility

Missouri serves as your base jurisdiction if your fleet is registered in the state, you maintain an established place of business with physical records, and your qualified motor vehicles accrue mileage on Missouri roadways. According to MoDOT, the physical business address cannot be a P.O. Box; it must be a location where the operational control and records of the fleet are maintained. If these conditions are met, you file a single application to cover travel in all 48 contiguous U.S. states and 10 Canadian provinces. If you only operate within the borders of Missouri, you do not need an IFTA license, but you must still comply with Missouri fuel tax laws for intrastate travel.

Application Process and Required Documentation

To apply, carriers must complete the Missouri IFTA Application (Form 4825). There is no fee for the initial IFTA license or the first set of decals in Missouri, which distinguishes it from many other states that charge per-vehicle fees. The application requires your Missouri Secretary of State charter number if you are incorporated, your USDOT number, and a list of all qualified vehicles. Applications can be submitted online through the MoDOT Carrier Express portal or via mail to the Motor Carrier Services office in Jefferson City. Processing typically takes 7 to 14 business days, after which decals are mailed to the registrant's address.

Decal Placement and License Requirements

Upon approval, MoDOT issues one paper license and two decals for each qualified vehicle. The original license or a legible photocopy must be kept inside the vehicle cab at all times. One decal must be permanently affixed to each side of the exterior of the cab. Failure to display valid decals can result in a citation and a fine, which varies by jurisdiction but often ranges from $100 to $500. Missouri decals are valid from January 1 through December 31, though there is a grace period until the end of February each year for displaying new decals, provided the carrier has applied for renewal by December 31.

Quarterly Tax Reporting Deadlines

Missouri IFTA licensees must file tax returns every quarter, even if no miles were traveled outside the state. The deadlines are strictly enforced: April 30 (Q1), July 31 (Q2), October 31 (Q3), and January 31 (Q4). If a deadline falls on a weekend or legal holiday, the return is due the next business day. Failure to file by these dates results in a penalty of $50 or 10% of the net tax due, whichever is greater. Interest is also applied to any late payments at a rate of 1% per month. MoDOT requires these filings to be submitted electronically through the MoDOT Carrier Express system unless a waiver is granted.

Record Keeping and Audit Compliance

Carriers are required to maintain detailed records for four years from the filing date. These records must include Individual Vehicle Mileage Records (IVMR), fuel receipts, and monthly summaries. According to IFTA Articles of Agreement, fuel receipts must show the date of purchase, name and address of the seller, number of gallons purchased, and the vehicle unit number. MoDOT conducts audits on approximately 3% of its IFTA licensees annually to verify the accuracy of reported miles and fuel. Discrepancies found during an audit can lead to significant back taxes, penalties, and the potential revocation of the IFTA license.

Missouri Fuel Tax Rates and Credits

The Missouri motor fuel tax rate for diesel is currently $0.245 per gallon as of 2024, following incremental increases mandated by Senate Bill 262. When filing a quarterly return, Missouri carriers calculate the tax owed by multiplying the total gallons consumed in each jurisdiction by that state's tax rate. You receive a credit for the tax already paid at the pump. If the tax paid at the pump exceeds the tax liability for the miles driven in a specific state, the carrier receives a credit that can be applied to future quarters or requested as a refund from MoDOT.

Frequently asked

What is the fee for Missouri IFTA decals?

Missouri does not currently charge a fee for IFTA decals or the annual license. This is managed through the MoDOT Motor Carrier Services division, though carriers must be in good standing with all other state tax obligations to receive them.

Can I get a temporary IFTA permit in Missouri?

Yes, if you need to travel before your decals arrive, you can obtain a 72-hour trip permit. This costs $10 per permit and allows a single vehicle to operate in Missouri without a permanent IFTA license, though you may need additional permits for other states on your route.

How do I renew my Missouri IFTA license?

Renewals are completed annually through the MoDOT Carrier Express online portal. The renewal period typically opens in October, and carriers must submit their application by December 31 to ensure they receive new decals before the grace period ends in February.

What happens if I lose my IFTA decals?

If decals are lost, stolen, or destroyed, you must apply for replacements through MoDOT. While the initial sets are free, there may be administrative procedures to verify the status of the vehicle before new decals are issued to replace the missing ones.

Do I need IFTA for a hot shot truck in Missouri?

You only need IFTA if the Gross Vehicle Weight Rating (GVWR) or the actual gross weight of the truck and trailer combination exceeds 26,000 pounds. If your hot shot setup is registered for 26,000 pounds or less and has only two axles, IFTA is generally not required.
