The launch sequence
Federal first, then Mississippi. The federal side is identical in every state and is covered in depth by how to get your own authority; the state facts below come from our sourced Mississippi data.
- Finish the federal registrations. Get your USDOT Number, plus federal operating authority and insurance filings if you will haul for hire across state lines. Mississippi does not require the USDOT Number for intrastate work, but MDOT and the Department of Revenue ask for it.
- Pay UCR before you file with MDOT. A carrier that has paid Unified Carrier Registration fees has MDOT's per-vehicle intrastate fee waived for the trucks claimed, so pay UCR first and put your USDOT and MC numbers on the receipt form.
- Mail the MDOT General Freight application. Send the General Freight application, Form MSR-1, a BOC-3 if you are based out of state, and payment to MDOT's Motor Carrier Section, with a certificate of insurance showing liability and cargo coverage on file.
- Open IRP and IFTA on TAP. If your trucks leave the state, apply for apportioned plates and an IFTA license on the Department of Revenue's TAP portal. A paid application can get temporary credentials the same day.
- License your drivers. Drivers get a CDL learner's permit and a CDL from the Department of Public Safety Driver Service Bureau, after entry-level driver training and a road test with DPS or a certified third-party tester.
The order that works in Mississippi
Start federal. Get the USDOT Number, and federal operating authority and insurance filings if you will haul for hire across state lines. Mississippi does not require the USDOT Number for intrastate work, but MDOT's application, IRP registration, and every oversize permit ask for it.
Next steps: file MDOT's General Freight application with Form MSR-1 and a certificate of insurance, then open an IRP account and an IFTA license on TAP if your trucks leave the state. Paying UCR first lets MDOT waive its per-vehicle intrastate fee for the trucks you claim.
Where Mississippi differs from other states
Three things catch new carriers. MDOT requires cargo insurance of every intrastate general freight carrier, a coverage federal rules ask only of household goods movers. Household goods and passenger carriers go to a hearing before their certificate issues. And one Department of Revenue office runs both IRP and IFTA, so a paid TAP application can bring temporary credentials the same day.
Costs to plan for
Budget for a one-time MDOT filing fee plus a per-vehicle fee, waived for trucks already covered by UCR. IFTA decals are free. Mississippi's share of an apportioned plate comes from two schedules, a privilege tax by weight and an additional privilege tax that falls with vehicle age. The exact amounts sit in the sourced fields below.
The Mississippi facts you will need
- State agency
- Mississippi Department of Transportation, Permit & Motor Carrier Division (Motor Carrier Section)
- State filing fee
- $50 (New carriers pay a one-time $50.00 registration (filing) fee plus $10.00 per vehicle. Renewals are $10.00 per vehicle. Per-vehicle fees are waived for carriers that have paid Unified Carrier Registration fees for the trucks claimed. Payment by credit card (not American Express), cashier's check, or money order payable to the Mississippi Department of Transportation; the MSR-1 receipt form also lists a personal check line.)
The complete tables live on the dedicated pages: intrastate authority, IRP registration, IFTA, and trucking permits.
Budget the launch before you file
The trucking startup cost calculator builds a line-item estimate from the sourced fee data, and the cost pillar explains every line. Neither replaces a quote for your truck and insurance, which are the two biggest variables.
Common mistakes when launching in Mississippi
Skipping cargo insurance on an intrastate freight filing
MDOT requires cargo coverage of every intrastate general freight carrier. Federal rules ask it only of household goods movers, so carriers used to federal filings often leave it off.
Paying MDOT per-vehicle fees you did not owe
Per-vehicle intrastate fees are waived for trucks already claimed under UCR, but only if you give MDOT your USDOT and MC numbers so it can verify the payment.
Applying for an oversize permit before UCR, IFTA, and IRP are current
MDOT issues no oversize or overweight permit until the carrier is current on UCR, IFTA, and IRP and has a federal DOT number and insurance naming MDOT on file.
Emailing the IFTA Excel template
The Department of Revenue wants the quarterly return keyed or uploaded in TAP with its current template. The old spreadsheet no longer works, and emailed templates are not accepted.
Moving a permitted load into a holiday
Permitted loads must stop at noon the day before named holidays and stay parked on the holiday unless the permit says otherwise.
Adding a new truck to the IRP fleet late
The Department of Revenue expects new vehicles added within a short window after purchase, and late additions draw penalties.
