Workers Compensation Requirements for North Dakota Contractors
North Dakota imposes a unique workers compensation structure on contractors operating within its borders — one that differs fundamentally from the private insurance markets used in most other states. All contractors with employees working in North Dakota must secure coverage through the state's exclusive workers compensation fund, administered by Workforce Safety & Insurance (WSI). Understanding this framework is essential for contractors bidding on projects, managing subcontractors, or entering the North Dakota market from another jurisdiction.
Definition and scope
Workers compensation in the North Dakota contractor context refers to the mandatory insurance coverage that pays medical expenses and wage-replacement benefits to employees injured on the job. North Dakota is one of four monopolistic workers compensation states in the United States — meaning coverage cannot be purchased through private insurers. All employers with employees working in North Dakota must obtain coverage exclusively through Workforce Safety & Insurance (WSI), the state agency that both administers and funds the program.
This requirement applies to virtually all contractors, including general contractors, specialty contractors, and firms working on public works projects. The obligation attaches to the physical location where work is performed — not to where the employer is incorporated or headquartered.
Scope and coverage limitations: This page addresses North Dakota workers compensation requirements as they apply to licensed and operating contractors within the state. It does not address federal workers compensation programs (such as the Federal Employees' Compensation Act or the Longshore and Harbor Workers' Compensation Act), which apply to specific federally regulated employment categories. Contractors working exclusively in other states are outside this page's scope, even if their business is registered in North Dakota.
How it works
Because North Dakota operates as a monopolistic state, contractors must register directly with WSI rather than shopping the private insurance market. The process follows a structured sequence:
- Employer registration: Contractors complete the WSI Employer Account Setup before the first employee begins work. Registration is conducted through WSI's online portal at workforcesafety.com.
- Classification assignment: WSI assigns each contractor a class code based on the type of work performed (e.g., roofing, excavation, electrical). Premium rates vary by class code and reflect the injury risk associated with each trade.
- Premium calculation: Premiums are calculated on estimated payroll. Contractors submit payroll estimates at policy inception and reconcile with actual payroll at year-end audit.
- Claim management: When a workplace injury occurs, the injured worker files directly with WSI. Benefits include medical care, temporary total disability payments, and permanent impairment awards — all administered by WSI.
Premium rates are set by WSI and expressed as dollars per $100 of payroll. Roofing and structural steel trades historically carry some of the highest class code rates, while administrative or supervisory classifications carry lower rates. Contractors can reduce effective premiums through WSI's experience rating modification system, which rewards low-claims histories with below-base-rate adjustments.
Contractors must also display their WSI registration status on certain licensing applications. The North Dakota contractor license requirements framework cross-references WSI coverage as part of qualification documentation.
Common scenarios
Scenario 1 — Out-of-state contractor entering North Dakota: A Minnesota-based excavation firm wins a contract in Bismarck. Despite carrying private workers compensation insurance in Minnesota, the firm must obtain WSI coverage for all employees performing work on North Dakota soil. The Minnesota policy does not satisfy the state requirement. See excavation contractor services for additional context on this trade category.
Scenario 2 — General contractor with subcontractors: A North Dakota general contractor subcontracts roofing work to a smaller firm. If the subcontractor does not carry valid WSI coverage, the general contractor may be held liable as the statutory employer for injuries to the subcontractor's employees. This exposure is a recurring compliance risk in the roofing contractor services segment. General contractors routinely require certificates of WSI coverage from all subs before work commences.
Scenario 3 — Sole proprietor with no employees: A sole proprietor operating without employees is not required to purchase WSI coverage under North Dakota law — but also receives no WSI benefits for personal injuries sustained on the job unless voluntarily enrolled. Voluntary coverage is available through WSI for sole proprietors and partners who wish to extend protection to themselves.
Scenario 4 — Independent contractor classification: Workers classified as independent contractors are generally not covered by the hiring contractor's WSI account. However, WSI applies a multi-factor test to determine true employment status, and misclassification of employees as independent contractors is an active enforcement area. Refer to subcontractor requirements for classification standards.
Decision boundaries
The primary classification question contractors face is whether a given worker triggers WSI coverage obligations. The distinction between employee and independent contractor determines this threshold, and WSI does not defer entirely to the contracting parties' own characterization.
Employee vs. independent contractor: WSI examines factors including behavioral control, financial control, and the nature of the working relationship — paralleling the IRS common law test but applied under North Dakota Century Code Chapter 65-04. A worker who follows detailed employer directives, uses employer-supplied equipment, and works exclusively for one firm is likely an employee for WSI purposes regardless of contract language.
Covered vs. exempt employment: Certain categories are statutorily exempt from WSI coverage requirements. These include sole proprietors without employees, corporate officers who own at least 10 percent of the corporation and elect to be excluded, and limited liability company members who elect exclusion in writing. The exclusion elections are documented with WSI and are not automatic.
Out-of-state policy sufficiency: No private policy — regardless of limits or endorsements — substitutes for WSI coverage when work is performed in North Dakota. This contrast with the 46 competitive workers compensation states is the single most important compliance distinction for contractors entering the state from outside.
Contractors subject to contractor safety regulations should also note that WSI coordinates with North Dakota's OSHA-approved State Plan framework, meaning safety violations can affect both regulatory standing and WSI experience ratings simultaneously.
