Workers' Comp for Janitorial in Wyoming (2026)

How workers' comp works for janitorial in Wyoming

Wyoming is one of four monopolistic workers' compensation states in the United States (along with North Dakota, Ohio, and Washington). Private workers' compensation insurance is not legally available in Wyoming, and self-insurance is not permitted for any employer. All coverage must be purchased exclusively through the Wyoming Department of Workforce Services — Workers' Safety & Compensation Division. Employers create an account at WYUI.wyo.gov, and DWS assigns the appropriate NAICS-based classification and rate.

Wyoming's coverage mandate is unique: it applies only to employers in "extra-hazardous" industries as defined by W.S. §27-14-108. NAICS Industry Group 5617 — Services to Buildings and Dwellings — is expressly enumerated as extra-hazardous under §27-14-108(a)(ii)(2). NAICS 561720 (Janitorial Services) falls within Industry Group 5617. Therefore, janitorial contractors operating in Wyoming are required to register with the WC Division and purchase state fund coverage before the first employee begins work. Failure to register exposes the employer to full personal liability for all employee claims and loss of the exclusive remedy protection.

Wyoming approved a 15% overall rate decrease effective January 1, 2026 — the third consecutive year of rate reductions (−6% in 2024, −12% in 2025, −15% in 2026), representing a total 33% reduction in three years and approximately $66 million in reduced premiums for Wyoming employers.

Class code and rate (2026)

• Wyoming uses NAICS codes — not NCCI or WCRB class codes — for all premium rating. NAICS 5617 (Services to Buildings and Dwellings, including 561720 Janitorial Services) is classified as extra-hazardous and requires mandatory state fund coverage.
• The 2026 overall rate decrease of -15% was approved by Governor Gordon and took effect January 1, 2026. The broader NAICS 561000 (Administrative & Support Services) sector rate for 2026 is $3.20/$100 payroll (down from $3.40 in 2025). The specific 5617/561720 industry rate is assigned by DWS upon employer registration at WYUI.wyo.gov — contact DWS Employer Services at (307) 777-6763 for the exact rate.
• Because Wyoming is monopolistic, there is no competition, no experience rating through private carriers, and no alternative placement. Your rate is the rate; DWS assigns it based on NAICS classification.

Indemnity benefits (Wyoming 2026)

• Wyoming benefit calculations are monthly-based (not purely weekly), tied to the quarterly statewide average monthly wage. TTD = 2/3 of the injured worker's average monthly wage, not to exceed the statewide average monthly wage (W.S. §27-14-403).
• Max monthly TTD: approximately $3,400–$3,577/month based on 2025 quarterly statewide average monthly wages ($5,100–$5,365/month × 2/3; per DWS wage reporting table at dws.wyo.gov). Weekly equivalent: approximately $785–$826/week.
• The SSA POMS chart records Wyoming's maximum weekly WC payment as approximately $1,177/week for January 2025 — note Wyoming resets quarterly, so the "maximum" varies within a year.
• Min monthly TTD: 30% of statewide average monthly wage — approximately $1,530/month (~$353/week) based on 2025 Q1 data (per DWS wage reporting table at dws.wyo.gov).
• Waiting period: 3 calendar days; if disability extends beyond 72 hours, benefits are paid from day 1 (W.S. §27-14-404).

Coverage thresholds and exemptions

• ALL employers operating in Wyoming must register with the WC Division (W.S. §27-14-207(a)) — including businesses that believe their NAICS code is optional.
• Extra-hazardous employers (including NAICS 5617 / 561720 janitorial) must purchase state fund coverage before the first employee begins work. No employee-count threshold applies.
• Optional-coverage employers (NAICS codes not enumerated as extra-hazardous under §27-14-108) may: (a) elect WC coverage through the state fund, (b) seek coverage with a private carrier, or (c) carry no coverage. If optional-coverage employers carry no WC insurance, injured employees retain full civil tort rights against the employer with no immunity protection.
• Corporate officers and LLC members may elect to have themselves covered under a separate affidavit process (available from DWS); coverage for officers is not automatic and requires a separate election form.

Failure-to-insure/failure-to-register penalty

Under W.S. §27-14-207, every employer operating in Wyoming must register with the Workers' Compensation Division. An extra-hazardous employer (including NAICS 5617 janitorial) that fails to register or purchase required state fund coverage is personally liable for all WC benefits owed to any injured employee and loses the exclusive remedy protection that ordinarily immunizes employers from tort suits. This means an injured janitorial worker could bring a full civil tort action against an unregistered Wyoming employer, recovering pain and suffering, loss of consortium, and other common-law damages unavailable under WC. Criminal penalties are available for willful noncompliance. DWS may also seek a court injunction prohibiting continued business operations.

Cost drivers specific to janitorial in Wyoming

• Top injuries (BLS NAICS 561720): slips/falls, back strains, chemical exposure — Wyoming's energy, mining, and tourism sectors create diverse janitorial contracts ranging from office cleaning to industrial facility maintenance, each with different hazard profiles.
• Wyoming's monopolistic structure means no market competition, no competitive underwriting, and no experience modification shopping between carriers. Premium is exactly what DWS calculates based on payroll and the assigned NAICS rate.
• The three-year rate reduction streak (total -33%) from 2024–2026 has meaningfully lowered WC costs for Wyoming janitorial operators — but rates remain above the national median due to the concentrated high-risk composition of the state fund risk pool.
• Wyoming's quarterly rate reset means benefit maximums fluctuate within a year — budget conservatively using the highest recent quarterly figure.
• All employers must register at WYUI.wyo.gov, which simultaneously handles unemployment insurance registration — a combined compliance step not found in other states.
• Bid-math note: at ~$2.72/$100 (indicative for NAICS 5617), load WC at approximately 2.7% of gross wages in Wyoming bids. Confirm exact rate with DWS after registration.
