How to Start a Trucking Business in New Hampshire

Starting a trucking company in New Hampshire requires coordination with the New Hampshire Department of Safety (NHDOS) and the Department of Transportation (NHDOT). Unlike some states, New Hampshire does not have a general state income tax on individuals, but businesses must navigate the Business Enterprise Tax (BET) and Business Profits Tax (BPT) if gross receipts exceed specific thresholds. New owners must first register their business entity with the New Hampshire Secretary of State, which involves a $100 filing fee for most Limited Liability Companies (LLCs). Once the legal structure is established, carriers must obtain federal authority if crossing state lines or hauling for-hire within the state. Operational success depends on managing regulatory deadlines and keeping accurate records for tax audits. DispatchTool streamlines this process by automatically tracking mileage by state line crossings, which simplifies the reporting required for the International Fuel Tax Agreement (IFTA). By utilizing integrated truck-safe routing, owners can avoid New Hampshire’s specific low-clearance bridges and weight-restricted rural routes while ensuring all trip data is ready for quarterly filings. New owners should create a DispatchTool account to centralize their HOS logs, IFTA data, and load documentation in one platform.

Business Entity Registration and Tax Structure

Before applying for a DOT number, you must register your business with the New Hampshire Secretary of State. As of 2024, the fee to form a domestic LLC is $100, while a Profit Corporation costs $100 plus a $50 technology fee. New Hampshire businesses are subject to the Business Enterprise Tax (BET) at a rate of 0.55% if gross business enterprise base exceeds $281,000. Additionally, the Business Profits Tax (BPT) is applied at 7.5% for businesses with gross income over $103,000. These thresholds are updated periodically by the New Hampshire Department of Revenue Administration (NHDRA).

Obtaining Federal and State Operating Authority

If you plan to operate as a for-hire carrier crossing state lines, you must obtain a USDOT number and Motor Carrier (MC) Authority through the FMCSA. The application fee for an MC number is $300. In New Hampshire, intrastate-only carriers hauling hazardous materials or operating vehicles with a GVWR over 10,000 pounds must also obtain a USDOT number. Furthermore, carriers must complete the Unified Carrier Registration (UCR). For a fleet of 0-2 trucks, the 2024 UCR fee is approximately $37, which supports state motor vehicle safety enforcement programs.

Insurance Requirements and BOC-3 Filing

New Hampshire follows federal guidelines for liability insurance under 49 CFR Part 387. For freight vehicles over 10,000 pounds GVWR, you must carry a minimum of $750,000 in primary liability insurance. If you haul hazardous materials, this requirement increases to either $1 million or $5 million depending on the material class. Additionally, you must file Form BOC-3 (Designation of Process Agents) with the FMCSA. Most process agent services charge a one-time fee between $25 and $50 to maintain a physical presence in every state you operate in.

New Hampshire IRP and IFTA Registration

If your trucks exceed 26,000 pounds GVWR or have three or more axles, you must register for the International Registration Plan (IRP) and International Fuel Tax Agreement (IFTA). In New Hampshire, these are administered by the Department of Safety, Division of Motor Vehicles. The IRP fee is not a flat rate; it is calculated based on the percentage of miles driven in each jurisdiction. For IFTA, New Hampshire issues a set of two decals per vehicle for an annual fee of $1.00 per set. You must file IFTA reports quarterly, even if no miles were driven during the period.

Vehicle Size and Weight Limits

New Hampshire RSA 266:18 dictates the legal weight limits for trucks on state highways. The maximum gross weight for a five-axle tractor-trailer is generally 80,000 pounds. Single axles are limited to 22,400 pounds, and tandem axles are limited to 36,000 pounds. Vehicles exceeding these dimensions require an Oversize/Overweight (OSOW) permit from the NHDOT Bureau of Turnpikes. Single-trip permits typically cost $25 plus additional mileage fees for weights exceeding 80,000 pounds. Drivers must be aware that many secondary roads in the White Mountains have strict spring thaw weight restrictions.

Commercial Driver License (CDL) Compliance

Drivers operating vehicles over 26,001 pounds must hold a valid New Hampshire CDL. The fee for a 5-year CDL is $60, plus a $10 application fee. Under FMCSA Clearinghouse regulations, employers must conduct a pre-employment query on all new drivers, which costs $1.25 per query. New Hampshire also requires a medical examiner's certificate (DOT Physical) to be updated every two years, or more frequently if the driver has specific health conditions like hypertension or sleep apnea.
