Wyoming's industry base rates run on the calendar year, and that is set in statute rather than by a filing. W.S. 27-14-201(c) requires the Department of Workforce Services to report proposed annual rate adjustments to the Joint Labor, Health and Social Services Interim Committee no later than October 1 of the year preceding the adjustment, and W.S. 27-14-201(c)(v) caps any increase "for the calendar year commencing January 1, 1999 and each calendar year thereafter" at 50% of the preceding year's base rate. The Division's actuarial reports are titled by calendar year, and the annual rate hearing is held the October before the rates take effect.
Wyoming operates a monopoly state fund through the Department of Workforce Services (DWS). All employers must purchase coverage from the state fund.
How Wyoming Actually Prices Workers' Comp
Wyoming classifies employers by NAICS industry code, not by NCCI class code. The Workers' Compensation Division sets an industry base rate for each NAICS classification; there is no NCCI manual rate to publish.

How DWS calculates your premium
Premium is the NAICS industry base rate applied to payroll per $100, adjusted by the employer's experience rating and by credits for an approved safety program, the Division's drug-and-alcohol testing program, health-and-safety consultation, or a deductible program. Industry base rates are set annually after a public hearing.
Why there is no class-code rate table on this page
A four-digit NCCI code does not identify a Wyoming classification, so pairing one with a rate would invent a class the state does not rate. Your Wyoming rate follows the NAICS classification DWS assigns when you register as an employer.
