Starting a Trucking Company in South Dakota: 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 Dakota is the second layer: where you get apportioned plates, who issues your fuel-tax license, whether South Dakota wants its own registration for trucks that never leave the state, and which state office checks on you. Here is that layer for South Dakota, checked against the state's own pages in September 2026.
In South Dakota one office handles both apportioned plates and the IFTA license - the South Dakota Department of Revenue. There is no separate South Dakota operating authority for general freight - the state layer is plates, fuel tax, the USDOT number and permits.
Interstate or South Dakota-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 Dakota's job is plates, fuel tax and roadside enforcement. Stay inside South Dakota and you are an intrastate carrier: no federal authority is needed, and South Dakota'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 Dakota-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 Dakota
South Dakota's IRP office is the South Dakota Department of Revenue, Motor Vehicle Division, Motor Carrier Section. To base a fleet in South Dakota you have to show a real connection to the state: South Dakota is the base jurisdiction if vehicles are registered in SD, their use is controlled from a South Dakota location, and operational records are maintained or can be made available there. Described as a one-stop shop for IRP and IFTA for SD-based interstate carriers; online system is Motor Carrier Connect (MCC). IRP will not be renewed if the carrier's USDOT number is out of service. Contact (605) 773-3541 or sdmotorcarrier@state.sd.us.
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 Dakota assigns you.
IFTA in South Dakota
The same office handles IFTA - the South Dakota Department of Revenue, Motor Vehicle Division, Motor Carrier Section. License and decal fee: $10 annual license; $2.50 per annual decal set. Filed through Motor Carrier Connect / SD Interstate Online.
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 Dakota
If the truck never leaves South Dakota you do not need federal operating authority, and South Dakota is not one of the states that requires a USDOT number for in-state-only trucks. South Dakota is not on FMCSA's list of states requiring a USDOT number for intrastate commerce. The sdtruckinfo FAQ describes the DOT number requirement only for carriers crossing state lines over 10,000 lbs and refers other cases to SDHP Motor Carrier Services (605-224-7364). 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.
South Dakota's official trucking site sends in-state-only carriers to their county treasurer for title, registration and commercial plates and lists no state operating authority for hauling general freight. If you want it in writing, the Highway Patrol's Motor Carrier Services office (605-224-7364) is the one to ask.
UCR when you are based in South Dakota
South Dakota 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 Dakota permits and programs
Oversize and overweight permits come from the South Dakota Highway Patrol, Motor Carrier Services (Ports of Entry) - SDAPS permitting system - 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 South Dakota
Roadside inspections in South Dakota are run by the South Dakota Highway Patrol, Motor Carrier Services, 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 Dakota Department of Revenue (or South Dakota commercial plates if the truck will never leave the state).
- Get your IFTA license and decals from the South Dakota Department of Revenue.
- Register for UCR at ucr.gov if you run interstate.
- Put the deadlines in the Stay Legal calendar: MCS-150 update, IFTA quarters, UCR, Form 2290, medical card, annual inspection.
Always confirm with South Dakota
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 South Dakota pages
Based in South Dakota? 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 South Dakota 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.
