Wyoming Workers Compensation Guide

Workers Compensation Requirements in Wyoming

Wyoming is a monopolistic workers' comp state — all employers must purchase coverage from Wyoming Workers' Compensation (WC), administered by the Department of Workforce Services. Private insurance is not available. Wyoming allows large employers meeting financial requirements to self-insure. Wyoming's energy, mining, and construction industries generate significant workers' comp claims.

Workers Comp Rates in Wyoming

Workers compensation premiums in Wyoming are calculated based on payroll, job classification (NCCI or state classification codes), and the employer's experience modification factor. The average rate of approximately $1.78 per $100 of payroll is a statewide blended average — actual rates vary significantly by job classification. A clerical office worker might pay $0.20-$0.40 per $100, while a roofing contractor might pay $15-$25 per $100.

For example, an employer with $1 million in payroll at the average rate of $1.78 per $100 would pay approximately $17,800 annually before experience modification adjustments. Employers with better-than-average loss experience (experience mod below 1.0) pay less; those with worse experience pay more.

What Makes Wyoming Unique

Wyoming's monopolistic system means all workers' comp coverage is provided by the state. Wyoming's energy sector — oil and gas production in the Powder River Basin — generates high-hazard workers' comp claims. Wyoming's remote geography means that when serious injuries occur, medical transport costs and treatment complexity can be significant.

Workers Comp Benefits in Wyoming

Wyoming provides temporary total disability at 80% of after-tax average weekly wages — among the more generous replacement rates nationally. Medical benefits cover necessary treatment. Permanent total disability provides ongoing wage replacement.

Employee Rights in Wyoming

Wyoming workers receive benefits directly from the state workers' comp program. Disputes are reviewed through the Office of Administrative Hearings with access to district courts.

How Workers Comp Premiums Are Calculated in Wyoming

Workers compensation premiums in Wyoming follow this basic formula: (Payroll / 100) × Classification Rate × Experience Modification Factor = Premium. The experience modification factor (EMR or X-Mod) compares your actual loss experience to the expected loss experience for your industry. An EMR of 1.0 is average; below 1.0 means better-than-average safety record (lower premiums); above 1.0 means worse-than-average (higher premiums).

Job classification codes are assigned based on the type of work employees perform. Accurate classification is critical — misclassifying employees into lower-risk categories can result in premium audits and significant back-premium assessments. An employer with employees in multiple classifications must track payroll by class code throughout the year.

How to Reduce Workers Comp Costs in Wyoming

Wyoming employers cannot shop for workers' comp but can reduce costs through safety performance. The state's experience modification system rewards strong safety records. Oil and gas employers in Gillette and Casper should invest heavily in safety training — the high injury rates in those industries create significant cost exposure. Self-insurance is an option for large qualifying employers.

• Implement a formal workplace safety program — documented safety training reduces injury frequency and improves experience modification over time.
• Develop a return-to-work program — getting injured workers back on modified duty reduces temporary disability claim duration and cost.
• Report all injuries promptly — early reporting enables timely medical treatment and claims management, reducing claim severity.
• Review job classifications annually — ensure employees are classified in the correct (not simply the lowest-cost) classification code.
• Work with a loss control specialist — many insurers offer free safety consultation services that identify hazard reduction opportunities.
