Employers must provide workers compensation when they have a covered employee who suffers a work‑related injury or illness, and the law in their state mandates coverage based on business size, industry, or payroll thresholds.

Legal triggers for coverage
Most U.S. states require any business with at least one employee to carry workers compensation, though some allow exemptions for sole proprietors or family‑only firms. Specific thresholds—such as $50,000 in annual payroll in California or 5 employees in Texas—determine when coverage becomes mandatory.
Industry‑specific risks
High‑hazard sectors like construction, manufacturing, and healthcare are almost always subject to compulsory coverage because the likelihood of on‑the‑job injuries is high. Low‑risk offices may qualify for exemptions if they meet state‑defined criteria.
Employee status matters
Full‑time, part‑time, temporary, and seasonal workers are generally covered, but independent contractors are not unless a court reclassifies them as employees. Misclassification can lead to penalties.
When an incident occurs
As soon as an employee reports a work‑related injury or illness, the employer must file a claim with the state workers compensation board and provide medical care within the statutory timeframe, usually within a few days.
Key compliance checklist
- Verify state‑specific payroll or employee‑count thresholds.
- Identify industry classifications that mandate coverage.
- Confirm worker status—employee vs. contractor.
- Maintain up‑to‑date insurance policy and post required notices.
- Report injuries promptly to the state agency.
