Workers' Compensation Rates in Wyoming (2026)

State Overview

Wyoming operates a monopoly state fund through the Department of Workforce Services (DWS). All employers must purchase coverage from the state fund.

How to find a Wyoming workers' comp class code from a job description

There is no Wyoming workers' comp class code for a job title. Coverage in Wyoming comes from the state fund, and DWS assigns the classification itself, and what gets classified is the employer's business — not the separate employments, occupations or operations inside it. "Machinist", "CNC operator", "general construction labor" and "data entry" are therefore work that sits inside whichever classification describes the business, not values you can look up on their own.

DWS publishes Wyoming's classifications in the Wyoming Workers' Compensation Industry Base Rates by Classification (the 2026 list, which runs on the calendar year because W.S. 27-14-201(c) sets the rate cycle in statute rather than by filing, and which prints each class's 2025 and 2026 base rate side by side). To confirm the classification for a specific business, use the Division's Industry Base Rates by Classification, published one list per year on the DWS employers page — that is the filed authority for Wyoming, and a code quoted from another state's manual is not. Wyoming is one of the few states that puts the burden on the agency. W.S. 27-14-201(a) lets any employer contest the classification the Division assigned by following the contested-case provisions of the Wyoming Administrative Procedure Act, "except that the division shall carry the burden of proving that the classification is correct". W.S. 27-14-201(b) then limits what a wrong one can cost: where a classification determination is found to be incorrect, premium under the corrected classification is charged only from the date of the change, not backdated.

Wyoming classifies by industry code, not by workers' comp class code. Coverage itself is defined by NAICS — W.S. 27-14-108(a)(ii) lists the covered sectors, subsectors and industry groups "as each is defined in the most recent edition of the North American Industry Classification System (NAICS) manual" — and the Division's rate list is keyed to six-digit NAICS numbers such as 236000 Construction of Buildings, so an NCCI code has nothing to attach to. The exceptions are numbered, not lettered: Wyoming carries five Special Exception Classification Codes, 000010 Clerical Office Occupations, 000020 Outside Sales, 000030 Inside Sales (Automotive Sales), 000040 Temporary Help – Office and 000050 Temporary Help – Other, which occupy the role 8810 and 8742 play elsewhere. And there is no self-service lookup to run first: DWS states that classifications and the rates tied to them are determined after the employer registration is submitted through WYUI, and that DWS assigns the classification once it has reviewed the registration.
