Workers’ compensation compliance is not a one-size-fits-all rule. The obligation usually depends on where employees work, headcount, industry, and whether owners or officers are included. A company legally exempt in one state may need coverage immediately after hiring in another. Multi-state employers should treat each work location as a separate compliance question.
What workers’ compensation insurance does
Workers’ compensation generally pays medical expenses and part of lost wages when an employee suffers a job-related injury or occupational illness. It may also provide rehabilitation, disability, and death benefits. In exchange, covered employers usually receive protection from many employee injury lawsuits.
This coverage is separate from general business insurance. A business owners policy or general liability policy normally does not replace workers’ compensation, and ordinary health insurance may exclude work-related injuries.
Workers compensation insurance requirements by state
The following 2026 overview groups states by their usual trigger for private employers. It is a starting point, not a substitute for checking current state guidance. Exemptions for farm labor, domestic work, casual labor, corporate officers, and family members can change the result.
States that generally require coverage with one employee
Coverage commonly begins with the first employee in Alaska, Arizona, California, Colorado, Connecticut, Delaware, Hawaii, Idaho, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Minnesota, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New York, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, Utah, Vermont, Washington, West Virginia, and Wyoming.
“One employee” can include a part-time worker and, depending on the state and structure, a corporate officer. Some states let qualifying officers, LLC members, partners, or sole proprietors reject coverage for themselves through a formal election, but that does not remove employees from the policy.
States with a three-employee threshold
Arkansas, Georgia, New Mexico, North Carolina, and Virginia generally require workers’ compensation at three employees. Part-time staff and certain officers may count. Construction, subcontracting, or licensing requirements can create an obligation even when direct headcount is below the normal threshold.
States with a four-employee threshold
Florida generally requires non-construction businesses with four or more employees to carry coverage, while construction employers usually need it with one or more employees. Agricultural employers follow separate tests. South Carolina generally applies its requirement at four employees, subject to exclusions.
States with a five-employee threshold
Alabama, Mississippi, Missouri, and Tennessee generally use a five-employee trigger for many private businesses. Industry exceptions matter. Missouri and Tennessee apply stricter rules to construction, and Tennessee generally requires construction employers with at least one employee to secure coverage. Alabama also has special construction provisions.
States with special payroll or work-pattern tests
Kansas generally requires coverage when annual payroll exceeds $20,000, although agricultural payroll is treated differently. Michigan generally covers private employers with three or more workers at one time, or those regularly employing at least one person for 35 or more hours per week for 13 weeks or longer during the preceding 52 weeks.
Wisconsin requires coverage at three employees, or when an employer has at least one employee and pays $500 or more in gross combined wages in a calendar quarter. Farms have a separate employee-and-days-worked test.
Texas and South Dakota
Most private Texas employers may choose whether to subscribe to the state workers’ compensation system. A non-subscriber must follow notice and reporting rules and gives up important legal defenses if an injured employee sues. Government entities must carry coverage, and certain government contractors may also need it.
South Dakota does not generally require employers to purchase workers’ compensation insurance, although the state recommends it. An uninsured employer can face a civil lawsuit after a workplace injury. In both states, contracts, lenders, clients, or project owners may demand a certificate even when state law does not.
Four compliance checks employers often miss
Count people, not only full-time positions
Part-time, seasonal, temporary, and family employees may count toward the threshold. Corporate officers can count in some jurisdictions even when they elect not to receive policy benefits. Maintain state-by-state headcount records.
Review worker classification
Calling someone an independent contractor does not make it legally true. Agencies examine control, independence, business structure, and the economic relationship. Misclassification can lead to back premiums, penalties, stop-work orders, and direct liability.
Check where remote employees work
A remote employee can create an obligation in the state where that person performs the job. For example, a Texas company hiring one remote employee in California should not assume Texas’s optional system controls. The California work location can trigger coverage from the first hire.
Collect certificates from subcontractors
General contractors may become responsible for injuries to uninsured subcontractor employees. Obtain current certificates before work begins, confirm policy dates, and repeat the check at renewal. Verify that the policy applies to the work and state involved.
A practical compliance process
Before hiring, identify every state where employees will work, confirm employee-count and industry rules with the state agency, and ask a licensed business insurance professional to structure the policy. Document owner exclusions, maintain payroll by state and class code, post required notices, report injuries promptly, and review coverage whenever the business expands or changes contractors.

Frequently asked questions
Does a part-time employee trigger coverage?
Often, yes. Many states count part-time employees when determining whether a business meets the threshold. Hours worked may matter under special tests, but employers should not exclude part-time staff automatically.
Do sole proprietors need workers’ compensation?
Sole proprietors without employees are commonly exempt from covering themselves, but may elect coverage. A client, general contractor, professional license, or project agreement may still require proof of insurance.
Can general liability insurance be used instead?
No. General liability usually addresses third-party injury or property-damage claims. Workers’ compensation is designed for employee work injuries and provides statutory benefits that general liability does not.
What happens if required coverage is not purchased?
Consequences vary by state and may include fines, stop-work orders, criminal penalties, back premiums, loss of legal protections, and direct responsibility for an injured worker’s medical costs and wage benefits.
Keeping coverage aligned with the law
The correct compliance decision starts with the employee’s work state, not the employer’s mailing address. Recheck the rules whenever headcount, payroll, industry, ownership, or work locations change. Because exemptions and thresholds can be revised, verify the requirement with the appropriate state agency before treating any business as exempt.
