3.3 Ohio Workers' Compensation Insurance

Ohio's State Monopoly System

Ohio operates a monopolistic (exclusive) state-fund workers' compensation system administered by the Ohio Bureau of Workers' Compensation (BWC). Unlike the roughly 25 states where private carriers compete and a handful that run "competitive" state funds, Ohio employers cannot buy workers' compensation from a private insurer at all.

Exam tip: This is the single most-tested Ohio casualty fact. The BWC is a STATE MONOPOLY — there is no commercial market for primary Ohio workers' comp. Producers may still place employer's liability / stop-gap coverage privately, because the monopolistic fund does NOT include employer's liability.

The four monopolistic states

Who Must Have Coverage

Ohio's mandate is broad — coverage attaches to nearly all employment relationships:

Penalties for non-compliance

An employer that fails to maintain coverage is a "non-complying employer" and faces:

• BWC stop-work exposure and fines
• Personal liability to pay an injured worker's claim plus reimburse the BWC's Statutory Surplus Fund for benefits it advances
• Loss of the usual exclusive-remedy protection — the worker may sue the employer directly
• Possible criminal prosecution for willful failure to comply

The exclusive-remedy bargain

Workers' compensation is built on a trade: the employee gives up the right to sue the employer in tort and, in exchange, receives benefits without having to prove fault. This exclusive remedy is the employer's key protection, and it disappears for a non-complying employer — which is why staying current with the BWC is far cheaper than facing an unlimited tort lawsuit. A narrow exception survives for an intentional tort, where Ohio (ORC 2745.01) lets an employee sue outside the system, but the bar is high: the employer must have acted with deliberate intent to cause injury.

Coverage and Rating Options

Because the BWC is the only insurer, an Ohio employer's choices are about how it participates, not who insures it.

State-fund programs

Self-insurance

Large, financially strong employers may self-insure with BWC approval (ORC 4123.35). They must demonstrate financial ability, post a surety bond or security deposit, pay claims directly (often through a third-party administrator), and submit to ongoing BWC oversight and reporting.

Premium Determination

The BWC sets rates using classic experience-rated factors:

The EMR is the key incentive: an employer with good loss experience earns a sub-1.0 modifier and lower premium, rewarding workplace safety; a poor history pushes the modifier above 1.0.

Benefits Provided

Wage-replacement details

Temporary-total payments are capped at the statewide average weekly wage (SAWW) — roughly $1,281/week for 2026 injuries. There is a 7-day waiting period before wage-loss benefits begin; if the disability lasts more than 14 days, benefits are paid retroactively to day one. Medical benefits, by contrast, start immediately with no waiting period.

Industrial Commission of Ohio

The Industrial Commission of Ohio is a separate agency from the BWC. The BWC administers and pays claims; the Industrial Commission adjudicates disputes — it hears contested claims, decides appeals from BWC orders, and determines permanent-disability awards through its district, staff, and full-commission hearing levels.

The stop-gap / employer's liability gap

One nuance producers must master: Ohio's monopolistic fund covers the statutory workers' compensation benefits but does not include employer's liability (the "Part Two" coverage that responds to suits such as third-party-over actions or loss-of-consortium claims arising from a workplace injury). Because the BWC leaves that gap, Ohio employers buy stop-gap employer's liability endorsements from private insurers — often attached to the CGL.

This is a rare instance where a producer can place workplace-injury-related coverage in the private market, and it is a frequent exam distinction from the "you cannot buy from private insurers" rule, which applies only to the primary indemnity coverage.

Producers servicing multistate employers should also flag extraterritorial issues: an Ohio-based worker temporarily injured in another state is generally still covered by the BWC, but an employer with permanent operations in other states needs separate coverage there, since the BWC does not write out-of-state exposure.
