How to Start a Trucking Company in South Dakota

Starting a trucking company in South Dakota requires coordination between the South Dakota Department of Revenue (DOR), the Department of Transportation (SDDOT), and federal agencies. South Dakota is a favorable state for motor carriers due to the lack of a state income tax and relatively streamlined registration processes for intrastate and interstate operations. However, carriers must strictly adhere to the South Dakota Codified Laws (SDCL) Title 32, which governs motor vehicle registration and weight limits. To begin, you must establish a legal business entity through the South Dakota Secretary of State, which involves a $150 filing fee for a Domestic LLC as of 2024. Before wheels hit the pavement, you must secure federal operating authority (MC number) if crossing state lines and a USDOT number regardless of interstate status if your vehicle exceeds 10,001 pounds. DispatchTool simplifies this transition by integrating IFTA reporting and truck-safe routing into one platform, allowing South Dakota owner-operators to track miles driven on Highway 14 or I-80 automatically for quarterly tax filings. You can create a DispatchTool account to manage your South Dakota trip permits and load documentation in a single dashboard.

Business Formation and Secretary of State Requirements

The first step in South Dakota is registering your business entity with the Secretary of State. Most small fleets choose a Limited Liability Company (LLC) or a Corporation. The Articles of Organization for an LLC cost $150 if filed online, or $165 for paper filings. You must also designate a Registered Agent with a physical South Dakota address to receive legal service. While South Dakota does not have a state corporate income tax, you are still responsible for federal taxes and must obtain an Employer Identification Number (EIN) from the IRS. This nine-digit number is required for opening business bank accounts and filing federal Department of the Treasury Form 2290 for Heavy Highway Vehicle Use Tax.

Securing Federal and State Operating Authority

If you plan to operate as a for-hire carrier crossing state lines, you must apply for Interstate Operating Authority (MC Number) via the FMCSA Unified Registration System (URS). The application fee is a one-time payment of $300. In addition to the MC number, you must obtain a USDOT number, which tracks your safety record. South Dakota requires a BOC-3 filing, which designates a process agent in every state you operate in, typically costing between $20 and $50. You must also complete the Unified Carrier Registration (UCR), which for 2024-2025 starts at approximately $37 for fleets with 0-2 power units, supporting the enforcement of safety programs across the nation.

South Dakota IRP and IFTA Registration

For carriers operating vehicles over 26,000 pounds Gross Vehicle Weight (GVW) or having three or more axles, registration for the International Registration Plan (IRP) and International Fuel Tax Agreement (IFTA) is mandatory. The South Dakota Department of Revenue manages these accounts through the Motor Carrier Services division. IRP fees are not fixed; they are apportioned based on the percentage of total miles driven in each jurisdiction. For example, if 50% of your miles are in South Dakota and 50% in Nebraska, your registration fees are split accordingly. IFTA requires a $10 fee for a set of two decals per vehicle, and quarterly tax returns must be filed even if no miles were driven.

Insurance Requirements and Form E Filings

South Dakota law and FMCSA regulations mandate specific insurance minimums. For non-hazardous freight moved in vehicles over 10,000 lbs GVW, the federal minimum is $750,000 in primary liability coverage. However, most brokers and shippers require a minimum of $1,000,000 in liability and $100,000 in cargo insurance. South Dakota requires a Form E filing from your insurance provider to the state to prove you meet the mandatory liability limits for intrastate operations. If you have employees, South Dakota law requires Workers' Compensation insurance, though sole proprietors with no employees may be exempt under specific SDCL 62-1-7 guidelines.

Heavy Highway Vehicle Use Tax (Form 2290)

If you operate a vehicle on public highways with a taxable gross weight of 55,000 pounds or more, you must file IRS Form 2290. The tax rate starts at $100 plus $22 per 1,000 pounds over 55,000, capping at $550 per year for vehicles over 75,000 pounds. You cannot register your plates with the South Dakota DOR without proof of payment (a stamped Schedule 1). The tax year runs from July 1st to June 30th, and the filing deadline is usually the last day of the month following the month the vehicle was first used on the road.

South Dakota Weight and Size Limits

The SDDOT enforces strict weight limits to protect infrastructure. The maximum gross vehicle weight on interstate highways is 80,000 pounds unless you have a specific permit. For non-interstate highways, the limit is often governed by the bridge formula, typically allowing 20,000 pounds on a single axle and 34,000 pounds on a tandem axle. Single units are limited to 45 feet in length, while a tractor-semitrailer combination generally has no overall length limit as long as the trailer does not exceed 53 feet. Overweight permits in South Dakota can be purchased for a minimum fee of $25 for a single trip, depending on the excess weight and distance traveled.
