Starting a Trucking Company in South Carolina: 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 South Carolina is the second layer: where you get apportioned plates, who issues your fuel-tax license, whether South Carolina wants its own registration for trucks that never leave the state, and which state office checks on you. Here is that layer for South Carolina, checked against the state's own pages in September 2026.

In South Carolina one office handles both apportioned plates and the IFTA license - the South Carolina Department of Motor Vehicles. South Carolina also has its own registration for trucks that haul for hire without leaving the state: the SCDMV Certificate of Compliance.

Interstate or South Carolina-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 South Carolina's job is plates, fuel tax and roadside enforcement. Stay inside South Carolina and you are an intrastate carrier: no federal authority is needed, and South Carolina'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 South Carolina-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 South Carolina

South Carolina's IRP office is the South Carolina Department of Motor Vehicles, Motor Carrier Services (MCS). To base a fleet in South Carolina you have to show a real connection to the state: established place of business requires four proofs in the business name at a non-residential business location (SC Secretary of State articles, commercial lease or deed, Form 941, business tax return); residency alternative requires three proofs in the individual's name. MCS is at 10311 Wilson Boulevard, Building C, Blythewood, SC 29016 (PO Box 1498). New accounts are opened through the online Motor Carrier Services portal (scdmvonline.com) with a valid USDOT and EIN; allow five business days for review. Required: title, proof of liability insurance, MC-7 records agreement, Form 2290, Schedule A/E and B. Replacement cab card $1, replacement plate $6, late penalties $10-$75.

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 South Carolina assigns you.

IFTA in South Carolina

The same office handles IFTA - the South Carolina Department of Motor Vehicles, Motor Carrier Services (MCS). License and decal fee: No charge for the IFTA decals. Apply with form IFTA-1 by mail or through the MCS online portal; mail-in renewals must arrive by December 1 and tax returns must be current through Q3 to renew.

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 South Carolina

If the truck never leaves South Carolina you do not need federal operating authority (the $300 filing) - but South Carolina is one of the states that still wants in-state-only trucks to hold a USDOT number. South Carolina is on FMCSA's list of states requiring intrastate CMV registrants to obtain a USDOT number. SCDMV also requires a valid USDOT before opening an IRP/IFTA account. The number is free, so get it early; almost every state form asks for it.

South Carolina also has its own registration for hauling other people's freight for hire inside the state: the SCDMV Certificate of Compliance (COC) for intrastate for-hire motor carriers (Class E-L or Class E-LC), issued by the South Carolina Department of Motor Vehicles, Motor Carrier Services. A COC is issued to all intrastate for-hire motor carriers except passenger, household goods, and hazardous-waste-for-disposal carriers, which instead need a certificate from the SC Public Service Commission / Office of Regulatory Staff (Class E). Apply with SCDMV Form COC; the name must match exactly on insurance filings and Articles of Incorporation/Organization.

Fee: Set by SCDMV (the Certificate of Compliance page does not list a dollar amount; ask Motor Carrier Services when you apply). Insurance: Minimum liability ranges from $300,000 to $5,000,000 depending on GVWR and whether hazardous materials are hauled; Class E-LC requires cargo insurance, Class E-L (low-value commodities such as dump truck materials) does not.

UCR when you are based in South Carolina

South Carolina 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. Carriers that only haul inside the state do not register for UCR at all.

Other South Carolina permits and programs

Oversize and overweight permits come from the South Carolina Department of Transportation, Oversize/Overweight (OSOW) Permit Office - every state wants its own permit for a load beyond the legal size or weight, and most now sell them online.

Other South Carolina-specific things a new one-truck carrier runs into:

• SC ORS / PSC Class E certificate (household goods or hazardous waste): Only carriers of household goods or hazardous waste (Class E) and passenger carriers need a PSC certificate of public convenience and necessity through ORS; general freight is handled by the SCDMV COC instead.
• SCDMV Motor Carrier Portal new-account review: New IRP/IFTA accounts require a valid USDOT and EIN plus four proofs of an established (non-residential) place of business or three proofs of residency; allow five business days for review before credentials are issued.

Who checks on you in South Carolina

Roadside inspections in South Carolina are run by the South Carolina Department of Public Safety, State Transport Police, 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 South Carolina Department of Motor Vehicles (or South Carolina commercial plates if the truck will never leave the state).
• Get your IFTA license and decals from the South Carolina Department of Motor Vehicles.
• Register for UCR at ucr.gov if you run interstate.
• If you will haul South Carolina-only loads, get the SCDMV Certificate of Compliance 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 South Carolina

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.
