Workers’ compensation is built for employee injuries on the job—medical costs and a portion of lost wages, generally without proving fault. Whether you must carry it depends on your state and headcount; guessing wrong is expensive.

For small businesses and contractors, it is also one of the highest-CPC commercial insurance topics in search, because premiums and compliance stakes are real.

What workers’ comp typically covers

Subject to state statutes and policy terms:

  • Reasonable medical treatment for work-related injuries/illnesses
  • Wage replacement benefits at state-set rates
  • Disability and vocational benefits in some cases
  • Death benefits for dependents in fatal work injuries

It generally does not replace general liability coverage for third-party injuries (customers slipping in your shop). See general liability for contractors.

Who must carry it?

Requirements are state-specific. Many states require coverage once you have employees; some have numeric thresholds; monopolistic states use state funds. Construction often faces stricter enforcement and certificate-of-insurance demands from general contractors.

Verify with your state workers’ compensation agency—not a blog checklist alone.

How cost is built (educational)

Insurers commonly price using:

  1. Classification codes — describe job risk (office vs roofing differ dramatically)
  2. Payroll — premium basis for many classes
  3. Experience modification factor — rewards or penalizes past loss history for eligible employers
  4. State — benefit levels and rate environments differ

Underestimating payroll or miscoding high-risk work can create audits and unexpected bills.

Certificates and contractors

If you bid jobs, upstream contractors may require proof of workers’ comp and may want to be listed appropriately on certificates. Lapses can halt payment applications.

Questions for your agent or state resource

  1. Am I required to carry workers’ comp with my current headcount and entity type?
  2. Which class codes apply to each role?
  3. How should owners/officers elect or exempt coverage where allowed?
  4. What happens at audit if payroll differs from estimates?
  5. Do I also need employers’ liability coverage (often paired)?

Frequently asked questions

Do I need workers’ comp if I have no employees?+

Sole proprietors without employees are often exempt, but rules vary by state—and hiring even one employee can change requirements. Contractors and LLCs should verify with state agencies.

Does workers’ comp cover independent contractors?+

Misclassification is a major risk. If a worker is legally an employee, they may need to be covered even if you call them a contractor. Get legal/HR guidance.

Why are quotes so different?+

Class codes, payroll estimates, experience modification, state, and insurer appetite drive price. Accurate payroll and class coding matter.
