Wyoming Workers’ Compensation

State fund coverage, who is excluded, the reporting clock, and the employer’s liability gap

The first time I helped set up a Wyoming crew, the owner called his insurance agent for a workers compensation quote and the agent told him he could not sell one. Not that the price was ugly, not that the class code was awkward. No private carrier writes that policy for Wyoming work at all.

Wyoming is one of four states that run a monopolistic workers compensation fund, and it takes the idea further than the other three. That single design choice reshapes everything downstream: where you register, who you call, what the coverage quietly leaves out, and what the state does to you if you skip it.

This page is Wyoming only. How the system works in general, from experience mods to return to work, sits in our guide to workers compensation insurance. The rest of the state picture, including hiring and pay rules, lives in the Wyoming HR compliance guide.

TL;DR
Wyoming sets no headcount threshold. Coverage is mandatory from the first employee if your NAICS classification appears in W.S. 27-14-108, and it can only come from the state fund. Every employer registers with DWS before starting work, even optional ones. Employees report within 72 hours, employers file within 10 days.

Everything below comes from the Wyoming Worker's Compensation Act (W.S. 27-14-101 and following) and the Department of Workforce Services. These rules change. The legislature amends the Act, the Division updates NAICS classifications to the current manual, and industry base rates are readjusted every year. Confirm anything you are about to act on with Wyoming DWS Employer Services before you rely on it.

Who Needs Coverage in Wyoming

There is no employee threshold in Wyoming. Coverage is mandatory from the first employee when the work falls in an extrahazardous classification, and optional when it does not. The test is what your business does, not how many people do it.

W.S. 27-14-108(a)(ii) lists the extrahazardous work by NAICS sector, subsector and industry group. The list is broader than the phrase suggests. Mining, utilities, construction and manufacturing are covered in full, and so is accommodation and food services, which means a restaurant with two cooks is mandatory coverage in Wyoming. Arts, entertainment and recreation is covered too, apart from a narrow exception the department may grant when a business earns most of its revenue from agriculture.

Other sectors are carved up piece by piece. Logging is mandatory while crop and animal production are not. Ambulatory health care, hospitals and nursing facilities are mandatory while most professional offices are not. Truck transportation, warehousing, gasoline stations, motor vehicle dealers, waste management, repair and maintenance, and services to buildings and dwellings all sit on the mandatory side. The full enumeration runs for several pages of the legislature's Title 27 compilation.

The classifications move. W.S. 27-14-108(a)(ii) points at the most recent edition of the NAICS manual, so a code that read as optional under an older edition can land on the mandatory list after an update. That is one reason the Division, not the employer, makes the call.

Compliance Risk
Registration is separate from coverage, and it is not optional for anyone. W.S. 27-14-207(a) says an employer subject to the Act shall not commence business or engage in work in Wyoming without applying for coverage and receiving a statement of coverage from the Division. The Department of Workforce Services applies that to every business: even one that turns out to be non-liable or optional has to register, because registration is how the Division makes that determination.
Your situationCoverage statusWhat you have to do
Any employee working in a NAICS class listed in W.S. 27-14-108(a)Mandatory from the first employeeRegister and hold a statement of coverage before work starts
NAICS class not listed in the statuteOptional under W.S. 27-14-108(j)Register anyway so the Division can classify you
Optional employer that elects state fund coverageCovered on the same termsElect for all employees, and stay in for at least two years
Owner, partner, corporate officer or LLC memberExcluded unless electedFile a written election under W.S. 27-14-108(k)
Out of state employer sending crews into WyomingSame NAICS test appliesRegister before starting work, plus advance premium deposit or surety bond
Business with no employees yetNothing to insureRegister when you hire, before the first day of work

Electing optional coverage is an all or nothing move. W.S. 27-14-108(j) lets an employer outside the mandatory list opt in, but only for every employee, and the election has to stay in place for at least two years before it can be withdrawn. Wyoming does not offer a middle setting where you insure the warehouse and leave the office out.

Who Wyoming Leaves Out

Wyoming excludes people by category rather than by counting them. The definition of employee in W.S. 27-14-102(a)(vii) ends with a list of who it does not include, and that list is where most of the surprises live.

CategoryHow Wyoming treats itAuthority
Sole proprietor or partner in a partnershipExcluded unless coverage is elected27-14-102(a)(vii)(B)
Corporate officerExcluded unless coverage is elected27-14-102(a)(vii)(C)
Limited liability company memberExcluded unless coverage is elected27-14-102(a)(vii)(P)
Independent contractorExcluded, under a three part statutory test27-14-102(a)(vii)(D)
Casual laborExcluded, defined as under two consecutive weeks and outside the normal course of business27-14-102(a)(vii)(A)
Employee of a private householdExcluded outright, with no election route27-14-102(a)(vii)(G)
Spouse or dependent of the employer living in the householdExcluded27-14-102(a)(vii)(E)
Agricultural laborCrop and animal production sit outside the mandatory list; logging does not27-14-108(a)(ii)(A)
Private duty nurse engaged by a private partyExcluded27-14-102(a)(vii)(H)
VolunteerExcluded unless covered as a listed public safety volunteer27-14-102(a)(vii)(K)
Federal employeeExcluded from the state act27-14-102(a)(vii)(J)
Owner operator leased with driver to a for hire carrierExcluded if the contract also treats them as a non employee for FICA, FUTA and withholding27-14-102(a)(vii)(O)
Licensed real estate broker, associate broker or salespersonExcluded for commission based licensed services27-14-102(a)(vii)(S)
Foster parent for the Department of Family ServicesExcluded27-14-102(a)(vii)(Q)
Elected official or appointed board memberExcluded, except county officers and legislators27-14-102(a)(vii)(N)

Two of those definitions are tighter than the everyday meaning of the words. Casual labor in W.S. 27-14-102(a)(xxiv) means service of less than two consecutive weeks that is also outside your normal course of business, so a second week of the same seasonal help does not qualify. Independent contractor status needs all three of freedom from control by contract and in fact, holding out to the public as self employed, and the right to substitute another person to do the work.

That three part test is the one that gets employers into trouble, because it is stricter than the tax rules people are used to. If the classification fails, the state fund treats the worker as your employee and the premium was owed all along. Our guide to worker misclassification covers how the same call plays out federally.

Owners who want to be covered have a form and a calendar to respect. Under W.S. 27-14-108(k), a corporation, LLC, partnership or sole proprietorship elects coverage for its officers, members, partners or proprietor by written notice at initial registration or 30 days before a calendar quarter begins. Electing for owners drags in any uncovered employees at the same time, and the election locks for eight calendar quarters.

Where a Wyoming Policy Comes From

There is one seller. Mandatory workers compensation coverage in Wyoming comes from the state fund administered by the Workers' Compensation Division of the Department of Workforce Services, and from nothing else. Private workers compensation policies are not sold for extrahazardous Wyoming work, and the Division put it in one line for the Joint Labor, Health and Social Services Committee: all required NAICS codes must have coverage through the state fund.

Self insurance is not an alternative either. The same Division briefing states that Wyoming has no statutory provision for self insurance regulation or enforcement, and nothing in the Act creates a qualifying process, a security deposit or a financial test for it. Where Ohio and Washington let large employers self insure, Wyoming simply does not have the mechanism.

The exception sits entirely on the optional side. Because an employer outside the enumerated NAICS codes is not subject to the mandate, what it does about coverage is its own choice. The Wyoming Department of Insurance describes the state fund as the primary provider and confirms that exempt employers may buy workers compensation from private insurers on the open market, with the Department regulating those insurers.

Practical note
If your classification is optional, you have three real choices and you should make one on purpose. Elect state fund coverage under W.S. 27-14-108(j). Buy a private policy on the open market. Or carry nothing, and accept that an injured employee has an ordinary lawsuit against you rather than a capped statutory claim.

Pricing works differently from a private market too, because there is no quote to shop. Under W.S. 27-14-201 the Division divides employment into classes, readjusts the rates annually on an actuarial basis, and applies an experience modification built from your own three year claim history. Discount programs for safety, for drug and alcohol testing and for a premium deductible can move the number further.

Base rates are set on a public calendar. W.S. 27-14-201(c) requires the department to submit proposed annual rate adjustments to the joint labor, health and social services interim committee no later than October 1 of the year before they take effect, so the coming year's rate change is visible in the autumn.

Reporting and payment follow the payroll rather than a policy anniversary. W.S. 27-14-202(a) requires a certified payroll report and payment on or before the last day of the month following the month in which the earnings were paid, with quarterly reporting available at the director's discretion for employers with a clean payment history.

Employers based elsewhere get one extra step. W.S. 27-14-302 requires a nonresident employer to register before starting work in Wyoming and to either pay an advance premium deposit or file a surety bond approved by the director, unless an extraterritorial certificate of coverage waives the requirement. Wyoming also refuses to let a contract be awarded to a nonresident employer until the required contributions are paid.

The Employer's Liability Gap

The state fund pays statutory benefits and nothing more. It is not the two part commercial policy sold in other states, so there is no Employer's Liability section sitting behind it to defend and pay when someone sues you over a workplace injury. In Wyoming that protection has to be bought separately.

The mechanism has a name worth using with your agent: a stop gap employer's liability endorsement, added to your commercial general liability policy by a private insurer. Ask for it by that name. A general liability policy on its own excludes bodily injury to employees, which means without the endorsement there is nothing behind that category of claim at all.

Why the gap is real in Wyoming
Exclusive remedy is conditional here. W.S. 27-14-104(a) puts the Act in place of other rights and remedies only against an employer making the contributions required by the Act. W.S. 27-14-104(c) then states the Act does not limit any right of action by an employee against an employer who has not qualified for coverage, or who has qualified but has not paid the required premium on the injured employee's earnings within 30 days of the date due. Immunity you assumed you had can be gone over a late payment.

The gap widens for anyone outside the definition of employee. If a worker is excluded, or if an optional employer never elected coverage, there is no statutory claim to be the exclusive remedy in the first place. What is left is an ordinary negligence suit, and that is precisely the exposure a stop gap endorsement is built for.

FirstHR is not an insurer or a broker, so this is not a product I can sell you. It is the single item Wyoming employers most often discover after a claim rather than before one, which is why it belongs on the list you take to your insurance agent this month.

Posters and What a New Hire Gets

Wyoming asks for one posting and one document kept on site. W.S. 27-14-507 requires each employer to keep posted in a conspicuous place for employees a notice furnished by the Division, containing a brief summary of the Act and the procedures for filing claims, and to keep a copy of the Act itself available for all employees.

The Department of Workforce Services supplies that notice inside its Wyoming labor law poster set, alongside the state minimum wage, unemployment insurance and occupational safety notices. The posters are free from the agency and from its workforce centers around the state, so an invoice arriving in the mail for a compliance poster is a sales pitch rather than a deadline. Our overview of workplace safety posters covers the federal set that hangs next to it.

On the new hire question, be careful with advice imported from other states. Wyoming's Act sets no requirement to hand a workers compensation pamphlet, brochure or written notice to an employee at hire. The obligation stops at the wall posting and the available copy of the Act. The Division publishes an Employers Guide to Reporting an Employee Injury as a resource, not as a mandated handout.

Practical note
Do it anyway. The 72 hour employee reporting deadline only works if people know it exists on their first day, and the presumption for a late report falls on the claim, not on you. Put the claim procedure, the Division contact and the name of the person who completes the report into your onboarding packet and handbook. That is exactly the kind of acknowledgment tracking I built FirstHR to keep in one place.

Injury Reporting Deadlines

Two clocks run at once, and they start at different moments. The employee has 72 hours to tell you, then 10 days to file a report. You have 10 days from the moment you were notified to file the employer's report with the Division.

WhoWhat is dueDeadlineAuthority
Employee to employerReport the occurrence and general nature of the accident, in writing or another approved formAs soon as practical, no later than 72 hours after the general nature of the injury became apparent27-14-502(a)
Employee to employer and DivisionFile the injury report itselfWithin 10 days after the injury became apparent27-14-502(a)
Employer to employeeAcknowledge a written injury report in writing on the report or a copyOn receipt27-14-502(b)
Employer to DivisionCertified employer’s injury report, stating whether the injury is compensableWithin 10 days after being notified of the injury27-14-506(a)
Employer to employeeMail or deliver a copy of the employer’s injury reportWith the filing27-14-506(a)
DivisionInitial review of entitlement to benefitsWithin 15 days after the injury report or claim is filed27-14-601(k)(i)
Any interested partyWritten request for a hearing on a final determinationWithin 15 days after the notice was mailed27-14-601(k)(iv)
EmployeeClaim for benefits, single incident injuryWithin one year of the injury or of discovery27-14-503(a)
EmployeeClaim for benefits, injury developing over timeWithin one year of diagnosis or three years from last exposure, whichever is later27-14-503(b)
Employer to DivisionCertified payroll report and premium paymentLast day of the month following the month earnings were paid27-14-202(a)

Missing the employee side of that schedule carries a specific consequence. W.S. 27-14-502(c) makes a failure to report to the employer and file the injury report a presumption that the claim shall be denied, rebuttable only by clear and convincing evidence that neither the employer nor the Division was prejudiced in investigating the injury and monitoring treatment.

Your own report has a criminal edge to it. Willful failure or gross negligence in reporting an occurrence that injured an employee is a misdemeanor under W.S. 27-14-506(c), punishable by a fine of up to $750, imprisonment for up to six months, or both.

Penalties for Going Without Coverage

Wyoming comes after the money first and the criminal record second, and the money side has no ceiling. An uninsured employer whose worker is awarded benefits owes the state the full value of that award.

ExposureWhat it means in practiceAuthority
Full cost of the claimAn employer that never applied for coverage, or that is over 30 days late on payments, is liable to the state for an amount equal to all awards paid and reserved for that employee, recovered by civil action in the director’s name27-14-203(a)
Interest on late premium1 percent per month, or any fraction of a month, from the due date until payment plus interest is received27-14-203(c)
Lien on your propertyThe director may file a lien covering all real and personal property of the employer in any county where it is filed27-14-203(e)
Injunction against operatingThe director may have the business enjoined, in whole or in part, from operating until payments are made and the employer complies27-14-203(f)
Delinquent payroll report$100 for each delinquent report, on top of any delinquent premium penalty27-14-202(j)
Loss of exclusive remedyThe employee keeps the right to sue the employer for damages instead of taking capped statutory benefits27-14-104(c)
Criminal, no account or no payroll reportKnowingly failing to establish an account or furnish a payroll report is a misdemeanor up to $750 and six months for a first conviction, and a felony up to $10,000 and ten years for a second or later one27-14-510(d)
Criminal, false payroll statementUnderstating payroll to cut premium is a misdemeanor below $500 avoided, and a felony up to $10,000 and ten years at $500 or more27-14-510(b)
Nonresident bond failureWillful failure by a nonresident employer to post the required bond is a misdemeanor up to $5,000, one year, or both27-14-307

One provision closes the escape route people hope for. W.S. 27-14-601(g) says no claim for benefits shall be denied based solely on the employer's failure to comply with the Act. The injured worker is paid either way, and the Division then turns to the employer for the cost.

Notice what the injunction in W.S. 27-14-203(f) actually is. Wyoming does not issue an administrative stop work order the way some states do. The director asks a court to enjoin the business from operating, in whole or in part, until the employer is current and compliant. The effect on a construction schedule is the same.

What to Do When Someone Gets Hurt

Work the sequence in order, because the deadlines that matter start on the day you were notified rather than the day the paperwork was convenient.

1
Get medical care, then write down the time
Treatment comes first. Record the moment the general nature of the injury became apparent, because both the employee’s 72 hour deadline and their 10 day filing deadline are measured from that point rather than from the shift or the pay period.
2
Take the report and acknowledge it in writing
W.S. 27-14-502(b) requires you to acknowledge a written injury report in writing, either on the report or on a copy. Do it the same day and keep the acknowledged copy. It is the cheapest evidence you will ever create.
3
Complete the Wyoming Report of Injury together
Wyoming uses one Report of Injury form, and the Division expects the injured worker and employer to complete it together. The injured worker signs it. The form and the submission channels sit on the DWS report an injury page.
4
File within 10 days and copy the employee
W.S. 27-14-506(a) gives you 10 days from being notified to file a certified employer’s injury report with the Division, and requires you to mail or deliver a copy to the employee. Late or careless filing is the misdemeanor in 27-14-506(c).
5
State your position on compensability, with reasons
The employer’s report has to say whether the injury is compensable and under the jurisdiction of the Act, or not compensable and why. If you say not compensable, no later claim is approved until the Division rules, so give real reasons rather than a reflex objection.
6
Run the safety reporting clock separately
Workers compensation filing is not OSHA reporting. Wyoming operates its own approved state plan through the DWS OSHA division, and the fatality and hospitalization deadlines there are far shorter than 10 days.
7
Watch the two 15 day windows
The Division makes its initial review within 15 days of the filing. Once a final determination is mailed, any interested party has 15 days to request a hearing before a hearing examiner. Diary both dates when the claim opens.

The Report of Injury reaches the Division by mail, email or fax, and the current addresses are published on the DWS report an injury page. Note that the Act contains no separate anti retaliation section of its own, which is not permission to act against a worker who reports. The general employment law analysis is in the state guide.

Keeping the safety and reporting side of this organized is ordinary operations work, not legal work. Written procedures, acknowledgments and a clear owner for the form beat a scramble on day nine. For the federal layer that sits over all of it, see our guide to OSHA requirements for employers.

Key Takeaways
Wyoming has no headcount threshold: coverage is mandatory from the first employee whenever the business sits in a NAICS class listed in W.S. 27-14-108(a)(ii), and optional when it does not.
Every employer registers with the Department of Workforce Services before starting work, including optional and out of state employers, because registration is how the Division classifies you.
Mandatory coverage comes only from the state fund, private workers compensation policies are not sold for it, and Wyoming has no statutory self insurance route at all.
The state fund carries no Employer’s Liability, so a stop gap employer’s liability endorsement on a commercial general liability policy from a private insurer is what closes that gap.
The reporting clock is 72 hours from employee to employer, 10 days for the employee’s injury report, and 10 days for the employer’s certified report to the Division.
Going without coverage means liability for the full value of the award under W.S. 27-14-203(a), loss of exclusive remedy, a possible injunction against operating, and criminal exposure that escalates to a felony on a second conviction.

Frequently Asked Questions

Does a Wyoming small business need workers compensation insurance?

That depends on your industry rather than your headcount, because Wyoming sets no employee threshold. Coverage is mandatory from the first employee when the work falls in one of the extrahazardous classes listed by NAICS code in W.S. 27-14-108(a)(ii), which sweeps in mining, utilities, construction, manufacturing, logging, accommodation and food services and most health care. Outside that list, state fund coverage is optional under W.S. 27-14-108(j). Registration is mandatory in both cases.

Can I buy Wyoming workers compensation from a private insurer?

Not for mandatory coverage. The Division told the Joint Labor, Health and Social Services Committee that all required NAICS codes must have coverage through the state fund, and the same briefing confirms Wyoming has no statutory provision for self insurance regulation or enforcement. The optional side is different: the Wyoming Department of Insurance states that exempt employers may buy workers compensation from private insurers on the open market, and it regulates those insurers.

Are corporate officers, LLC members and sole proprietors covered?

Not automatically. W.S. 27-14-102(a)(vii) leaves sole proprietors, partners, corporate officers and LLC members out of the definition of employee unless coverage is elected under W.S. 27-14-108(k). The election is a written notice to the Division at initial registration or 30 days before a calendar quarter starts. It pulls in any uncovered employees at the same time, and it cannot be withdrawn for eight calendar quarters.

How fast does a Wyoming workplace injury have to be reported?

The employee has 72 hours to report the occurrence and general nature of the accident to you, measured from when the general nature of the injury became apparent, plus 10 days to file the injury report with you and the Division under W.S. 27-14-502(a). You then have 10 days from being notified to file a certified employer's report and send the employee a copy, under W.S. 27-14-506(a). The claim for benefits itself carries a one year limit.

What happens to a Wyoming employer with no coverage?

The civil bill comes first and it is uncapped. W.S. 27-14-203(a) makes an employer that never applied for coverage, or that is more than 30 days late on payments, liable to the state for an amount equal to every award paid and reserved for that employee. Add 1 percent monthly interest, a lien on all real and personal property, and a court injunction against operating. W.S. 27-14-104(c) also strips exclusive remedy, so the employee can sue.

Does the Wyoming state fund include employer's liability coverage?

No. The fund pays the statutory benefits in the Act and stops there, so there is no Employer's Liability part behind it. Wyoming employers close the gap with a stop gap employer's liability endorsement on a commercial general liability policy from a private insurer, because that policy on its own excludes bodily injury to employees. The exclusive remedy in W.S. 27-14-104(a) reaches only employers making the contributions the Act requires.

Do I still register with DWS if my industry is optional?

Yes. W.S. 27-14-207(a) bars an employer subject to the Act from commencing business or engaging in work in Wyoming without applying for coverage and receiving a statement of coverage. The Department of Workforce Services applies that to everyone, because registration is what lets the Division assign your NAICS classification and decide whether you are mandatory, optional or non liable. Out of state employers also post an advance premium deposit or a surety bond unless a certificate waives it.

Pay rules and the rest of the state picture sit alongside this one. See the Wyoming minimum wage page for the wage floor, and the state compliance guide for everything else an employer here has to hold.
