Funding Sources
Workers compensation is primarily funded by employers, who either purchase commercial insurance policies, self‑insure if they meet financial criteria, or contribute to state‑run funds where private coverage is unavailable.

Employer‑Purchased Insurance
Most businesses buy policies from private insurers. Premiums are calculated based on payroll, job risk classifications, and claim history, and are paid regularly to keep coverage active.
Self‑Insurance
Large employers with sufficient financial resources may obtain a self‑insurance license from the state. They collect the same premium amounts they would pay to an insurer but manage claims and payouts internally, subject to state oversight.
State Funds and Assigned Risk Pools
When private insurance is scarce or prohibitively expensive, states operate their own workers compensation funds or assign high‑risk employers to a pooled program, spreading costs across all participating firms.
Premium Allocation
Premiums cover two core obligations: medical treatment for work‑related injuries and wage replacement for time off work. A portion also funds administrative costs and the state's regulatory framework.
Key Differences by State
While the funding model is consistent—employer responsibility—the exact mechanisms, rates, and availability of state funds vary widely across jurisdictions, reflecting local labor markets and legislative choices.
