How to Start a Trucking Business in Mississippi

Launching a trucking company in Mississippi requires coordinating with the Mississippi Secretary of State (SOS), the Mississippi Department of Revenue (DOR), and the Mississippi Department of Transportation (MDOT). For-hire motor carriers must first establish a legal business entity, such as an LLC or Corporation, which involves a $50 filing fee for the Articles of Organization. Beyond basic business registration, carriers must obtain a USDOT number and, if crossing state lines, Operating Authority (MC Number) from the Federal Motor Carrier Safety Administration (FMCSA). Mississippi is a member of the International Registration Plan (IRP) and the International Fuel Tax Agreement (IFTA), meaning carriers based here must register their apportioned plates and fuel accounts through the DOR’s Petroleum Tax Division. Effective management of these regulatory deadlines is essential to avoid fines or an Out-of-Service order. DispatchTool provides a centralized platform for managing IFTA reporting and truck-safe routing that accounts for Mississippi’s specific weight limits on state highways. By integrating dispatch data with distance tracking, the software simplifies the quarterly filing process required by the Mississippi Department of Revenue. To begin organizing your compliance documents and dispatch workflow, you can create a DispatchTool account to start your 14-day trial.

Mississippi Secretary of State Business Formation

The first step is registering a legal entity through the Mississippi Secretary of State’s online portal. Most owner-operators select a Limited Liability Company (LLC) structure to protect personal assets. The filing fee is $50, and you must appoint a registered agent with a physical Mississippi address. Once the SOS approves the formation, the business must apply for a federal Employer Identification Number (EIN) from the IRS, which is free of charge. You will also need to file an Annual Report with the SOS between January 1 and April 15 each year to remain in good standing; failing to do so results in administrative dissolution and a $50 reinstatement fee.

USDOT and MC Number Requirements

All commercial motor vehicles (CMVs) with a Gross Vehicle Weight Rating (GVWR) of over 10,001 pounds must have a USDOT number. If you intend to haul regulated commodities for hire across state lines, you must also obtain an MC Number. The FMCSA charges a $300 application fee for Operating Authority. Once the application is submitted, there is a 10-day protest period. During this time, carriers must file proof of liability insurance (Form BMC-91 or BMC-91X) and a BOC-3 form designating a process agent. Mississippi requires a minimum of $750,000 in primary liability coverage for general freight, though many brokers require $1,000,000.

Mississippi IRP and IFTA Registration

Mississippi-based carriers operating vehicles over 26,000 lbs GVWR or having three or more axles must register for IRP and IFTA. The Mississippi Department of Revenue handles these applications via the TAP (Taxpayer Access Point) portal. IRP fees are not fixed; they are calculated based on the percentage of miles driven in each jurisdiction. For example, if 50% of your miles are in Mississippi and 50% in Alabama, your registration fee is split accordingly. IFTA requires a $10 fee for a set of two decals per vehicle. Carriers must file quarterly fuel tax reports even if no miles were driven during the quarter, with a $50 penalty for late filings.

Unified Carrier Registration (UCR) and HVUT

Mississippi participates in the Unified Carrier Registration agreement, which replaces the old Single State Registration System. Fees for UCR are based on the total number of commercial vehicles in your fleet. For 2024, the fee for a fleet of 0-2 vehicles is approximately $37. Additionally, any vehicle with a gross weight of 55,000 pounds or more must pay the Heavy Vehicle Use Tax (HVUT) to the IRS using Form 2290. The base tax is $100 plus $22 for every 1,000 pounds over 55,000, capped at $550 annually. You must present a stamped Schedule 1 from Form 2290 to the Mississippi DOR to obtain your license plates.

Mississippi Weight and Size Limits

The Mississippi Department of Transportation (MDOT) enforces strict weight limits to preserve infrastructure. On the Interstate system, the maximum gross vehicle weight is 80,000 pounds without a permit. The maximum width is 8.5 feet, and the maximum height is 13.5 feet. Mississippi allows for a 'tolerance' on certain non-interstate highways, but carriers must be aware that bridge weight limits vary significantly across the Delta and coastal regions. Overweight permits can be obtained through the MDOT's automated permit system for a fee, typically starting at $10 plus mileage charges for specific overweight loads.

Drug and Alcohol Clearinghouse Compliance

Before a Mississippi carrier can allow a driver to operate a CMV, the driver must be registered in the FMCSA Drug and Alcohol Clearinghouse. As an owner-operator, you must fulfill the roles of both 'employer' and 'driver.' This includes conducting a pre-employment query and an annual query for all drivers. You must also join a random drug testing consortium, as a single-truck entity cannot manage its own random testing pool. Failure to comply with these federal mandates can result in fines exceeding $5,000 per violation during an MDOT or FMCSA roadside inspection or audit.
