Wyoming Workers' Compensation Guide for Contractors and Small Businesses
In Wyoming, all employers—including contractors and small businesses with even one employee—must carry workers' compensation insurance through the state-run Wyoming Workers’ Safety and Compensation Division (formerly part of the Department of Workforce Services). Unlike many states, Wyoming does not allow private insurers; coverage is exclusively provided by the state fund. Failure to comply triggers immediate penalties and liability exposure.
Mandatory Coverage and Employer Requirements
Wyoming law (W.S. § 27-14-102) mandates that every employer engaged in hazardous employment—including construction, roofing, electrical, plumbing, and general contracting—must secure workers’ compensation coverage for all employees, regardless of hours worked or employment status (full-time, part-time, seasonal, or temporary). This applies to sole proprietors who hire even one worker. Independent contractors are exempt only if they meet strict statutory criteria: they must operate under a written contract, maintain separate business identity (EIN, business license, insurance), control their own methods and means of work, and not be subject to employer supervision. Misclassification carries severe consequences: the employer remains liable for all benefits and penalties. The Wyoming Workers’ Safety and Compensation Division (WSCD) enforces compliance through audits, payroll reviews, and third-party reporting. Employers must report new hires within 20 days and file annual payroll reports by February 28. Coverage begins immediately upon hiring—the first day an employee performs work triggers legal obligation. No grace period exists, and retroactive coverage is not permitted.
Exemptions and Independent Contractor Rules
Wyoming permits very limited exemptions from workers’ compensation coverage. Sole proprietors, partners, and corporate officers may elect exclusion—but only if they file Form WSCD-101 with the Wyoming Workers’ Safety and Compensation Division and meet eligibility requirements (e.g., owning ≥10% equity, performing no manual labor). Excluded individuals cannot later claim benefits for injuries sustained during excluded periods. Crucially, independent contractors are *not automatically exempt*: they must satisfy all six statutory tests under W.S. § 27-14-105(a)(ii), including operating under a written contract, maintaining separate business premises, holding liability insurance, furnishing tools/equipment, bearing profit/loss risk, and exercising independent judgment over work performance. The WSCD evaluates misclassification on a case-by-case basis using the ‘economic realities’ test—not just contractual language. Contractors misclassified as independent often trigger employer liability for unpaid premiums, interest, and civil penalties up to $1,000 per unreported employee per violation. Employers should retain documentation—including contracts, invoices, business licenses, and insurance certificates—for at least five years to defend classification decisions during audits.
Premium Calculation and State Fund Mechanics
Wyoming operates a monopolistic state fund—private insurance carriers are prohibited from selling workers’ compensation in the state. All premiums are calculated and administered solely by the Wyoming Workers’ Safety and Compensation Division (WSCD). Premiums are based on gross payroll, industry-specific base rates (updated annually), and individual employer experience modification factors (mod rate). Base rates range from $0.22 to $13.98 per $100 of payroll, depending on class code (e.g., Class Code 5606 for general contractors is currently $5.28). The mod rate reflects an employer’s three-year claims history relative to industry peers: a mod < 1.0 reduces premiums; > 1.0 increases them. New employers receive a mod of 1.0 for their first three years. Payroll reporting is mandatory quarterly (by April 30, July 31, October 31, and January 31), with final reconciliation due February 28. Late filings incur 1.5% monthly interest plus $25 late fees. Employers may qualify for safety incentive discounts (up to 10%) via WSCD’s Safety Recognition Program, requiring documented loss prevention plans and OSHA 300 logs. Premiums are non-refundable except for verified payroll reductions or business closure—refunds require formal application and audit verification.
Claims Process and Penalties for Noncompliance
When a work-related injury occurs in Wyoming, employers must report it to the WSCD within 24 hours via the online e-Report system or by phone, then file a completed First Report of Injury (Form WSCD-102) within seven calendar days. Medical treatment must be authorized by the WSCD or designated provider network; unauthorized care may not be covered. Employees retain the right to choose their treating physician, but referrals to specialists require WSCD pre-approval. Claims are adjudicated by WSCD claims adjusters—not courts—and disputes go before the Office of Administrative Hearings. Penalties for noncompliance are steep: failure to secure coverage incurs fines up to $1,000 per employee per day, plus criminal misdemeanor charges (W.S. § 27-14-501). Unpaid premiums accrue 1.5% monthly interest and $25 late fees. Willful failure may result in business license suspension, wage garnishment, and personal liability for unpaid benefits—including medical costs, lost wages, and permanent disability awards. Repeat violations trigger enhanced penalties and mandatory safety consultations. Employers must post the official WSCD Notice to Employees (Form WSCD-105) in a conspicuous workplace location; failure to do so carries a $500 fine per occurrence.

Do I need workers' comp if I’m a sole proprietor with no employees in Wyoming?
No—you are not required to carry workers’ compensation if you have zero employees. However, if you hire even one person—even temporarily—you must obtain coverage immediately. Sole proprietors may voluntarily elect coverage for themselves by filing Form WSCD-101, but this requires meeting equity and operational criteria and is irrevocable for one year.
Can I use my out-of-state workers' comp policy for my Wyoming job site?
No. Wyoming prohibits private insurance and requires all employers operating in the state to use the Wyoming Workers’ Safety and Compensation Division fund. An out-of-state policy provides no legal protection in Wyoming and leaves you fully exposed to penalties, fines, and personal liability for any workplace injury.
What happens if one of my subcontractors gets injured on my Wyoming jobsite?
If the subcontractor is misclassified—that is, fails to meet all six W.S. § 27-14-105(a)(ii) tests—you, as the general contractor, become the statutory employer liable for their workers’ comp benefits. Wyoming law imposes joint and several liability on upstream contractors who engage unsecured or improperly classified subs, regardless of contract terms.
