Starting a Trucking Company in Mississippi: The State-Level Steps
Updated September 2026
Your USDOT number and operating authority come from FMCSA and work the same in every state. What changes when you are based in Mississippi is the second layer: where you get apportioned plates, who issues your fuel-tax license, whether Mississippi wants its own registration for trucks that never leave the state, and which state office checks on you. Here is that layer for Mississippi, checked against the state's own pages in September 2026.
In Mississippi one office handles both apportioned plates and the IFTA license - the Mississippi Department of Revenue. Mississippi also has its own registration for trucks that haul for hire without leaving the state: the Mississippi Intrastate General Freight Operating Authority.
Interstate or Mississippi-only? Decide this first
Two different rulebooks apply depending on where the truck goes. Cross a state line for pay and you are an interstate carrier: FMCSA issues your USDOT number and operating authority (the $300 filing) and sets the insurance and BOC-3 rules, and Mississippi's job is plates, fuel tax and roadside enforcement. Stay inside Mississippi and you are an intrastate carrier: no federal authority is needed, and Mississippi's own rules take over - covered in the in-state section below.
Most new owner-operators run interstate, so this page assumes that unless it says otherwise. If you are truly Mississippi-only, you register the truck and its fuel with the state instead of IRP and IFTA, and the in-state section is the one to read closely.
Apportioned plates (IRP) in Mississippi
Mississippi's IRP office is the Mississippi Department of Revenue - IRP Section (Interstate Commercial Vehicles). To base a fleet in Mississippi you have to show a real connection to the state: carrier must have an established place of business in Mississippi (a physical structure owned or leased, open and staffed during regular business hours), accrue Mississippi distance, and keep records available (per IRP manual). Apply and manage IRP accounts through TAP (tap.dor.ms.gov); a USDOT number, taxpayer ID and current MCS-150 are required; IRP office at 500 Clinton Center Dr, Clinton, MS (601-923-7142).
Bring what every IRP office wants: your USDOT number and EIN, the truck's title or lease, proof of insurance, and a stamped Form 2290 Schedule 1 if the truck is 55,000 lbs or heavier. Fees are split among the states by the share of miles you run in each, so nobody can quote a flat price up front - the states that publish an estimate put a first-year 80,000 lb plate at roughly $1,250 to $2,500. You renew every year in the month Mississippi assigns you.
IFTA in Mississippi
The same office handles IFTA - the Mississippi Department of Revenue - IFTA/IRP (Interstate Commercial Vehicles).
Once licensed you file a quarterly return - due April 30, July 31, October 31 and January 31 - even for a quarter with zero miles. Keep every fuel receipt and your miles by state; the return is built from them. The license expires December 31 and is renewed every year.
Hauling only inside Mississippi
If the truck never leaves Mississippi you do not need federal operating authority, and Mississippi is not one of the states that requires a USDOT number for in-state-only trucks. Mississippi is not on FMCSA's list of states requiring USDOT numbers for intrastate carriers. Note that MDOT's intrastate authority application has a USDOT number field and MDOT's permit manual requires a valid federal DOT number for OS/OW permits. Most carriers get the free number anyway: many state forms ask for it, and you will need it the day you cross a state line.
Mississippi also has its own registration for hauling other people's freight for hire inside the state: the Mississippi Intrastate General Freight Operating Authority, issued by the Mississippi Department of Transportation, Motor Carrier Section (Permit and Motor Carrier Division). MDOT's Motor Carrier Section issues Intrastate General Freight Operating Authority to carriers hauling for hire inside Mississippi. The application goes to MDOT Motor Carrier Section/66-05, P.O. Box 1850, Jackson, MS 39215-1850, with proof of liability and cargo insurance on file.
Fee: $50 registration for new carriers plus $10 per vehicle; fees waived for carriers that participate in UCR. Insurance: $750,000 liability for non-hazardous property (higher for hazmat); cargo insurance $5,000 (loads of 3 tons or under) or $10,000 (over 3 tons).
UCR when you are based in Mississippi
Mississippi takes part in the Unified Carrier Registration program. Interstate carriers register once a year at ucr.gov - $46 for 0-2 trucks in 2026, $55 in 2027. MDOT waives intrastate authority fees for UCR participants. Carriers that only haul inside the state do not register for UCR at all.
Other Mississippi permits and programs
Oversize and overweight permits come from the Mississippi Department of Transportation, Permit and Motor Carrier Division (ExpressPass at permits.mdot.ms.gov) - every state wants its own permit for a load beyond the legal size or weight, and most now sell them online.
Who checks on you in Mississippi
Roadside inspections in Mississippi are run by the Mississippi Department of Public Safety (roadside) and the MDOT Office of Enforcement (permits and weights), working with FMCSA. Expect the New Entrant safety audit within your first 12 months of interstate operation - the walkthrough's audit checklist covers the 16 things that fail it automatically.
The order to do it in
- Form the business and get a free EIN from the IRS.
- Get your USDOT number (free) through FMCSA's Motus system - and apply for operating authority ($300) if you will ever cross a state line.
- Have your insurer file the federal proof of insurance and hire a process agent for the BOC-3.
- File Form 2290 with the IRS if the truck is 55,000 lbs or heavier and keep the stamped Schedule 1 - the plate office asks for it.
- Get apportioned plates from the Mississippi Department of Revenue (or Mississippi commercial plates if the truck will never leave the state).
- Get your IFTA license and decals from the Mississippi Department of Revenue.
- Register for UCR at ucr.gov if you run interstate.
- If you will haul Mississippi-only loads, get the Mississippi Intrastate General Freight Operating Authority before the first one.
- Put the deadlines in the Stay Legal calendar: MCS-150 update, IFTA quarters, UCR, Form 2290, medical card, annual inspection.
Always confirm with Mississippi
Fees and forms move without notice. Before you pay anyone, open the official pages below and check the current figures - it takes ten minutes and prevents expensive surprises. HaulLegal is not the government, is not a law firm, and never files anything for you; you do every step yourself.
Official Mississippi pages
Based in Mississippi? The walkthrough puts all of this in order.
The HaulLegal walkthrough lays out every step from the business filing to your first safety audit, federal and state, with the real government fee beside each one - and the Stay Legal calendar turns your USDOT number and dates into a deadline list that emails you before each one. The first four steps are free, no signup.
One thing every Mississippi carrier needs no matter which state they are based in: a self-employed CDL driver has to be in a drug and alcohol random testing pool run by a consortium before the first mile, and having no program and no random pool are two of the sixteen automatic failures on the New Entrant safety audit.
