Ohio business insurance requirements

Ohio is one of four monopolistic workers' compensation states. An Ohio employer with even one employee gets comp from the Bureau of Workers' Compensation or qualifies to self-insure; no private carrier may sell it. The BWC policy covers statutory benefits only, so Ohio businesses buy stop-gap employers' liability from a private insurer to handle the lawsuits comp does not bar, including Ohio's employer intentional tort claims. Ohio's tort law is otherwise friendly to defendants: a 51% comparative fault bar, a two-year injury statute and caps on noneconomic damages.

Workers' compensation requirements

The comp law reaches every private employer that has "one or more employees" regularly in the same business (ORC 4123.01). The employer must pay premium into the state insurance fund or be granted the privilege of self-insuring (4123.35). Household and casual workers count once they earn $160 or more in cash in a calendar quarter from one employer.

Owners split by entity type. Corporate officers are employees and must be covered, with two exceptions: an individual incorporated as a corporation with no employees, and officers of a family farm corporation. Those two groups, along with sole proprietors and partners, are outside the definition of employee but may elect coverage by written notice to BWC; no benefits are paid to them until BWC receives that notice. The definition of employee in ORC 4123.01 does not mention limited liability companies or their members at all, so LLC owners should confirm their status with BWC, which looks at how the LLC is organized and taxed. See can owners and officers exclude themselves from workers' comp?.

The construction rule sits inside the definition of employee: anyone working for a contractor or subcontractor that has not paid its BWC premium "shall be considered as the employee of" whoever contracted with that contractor (4123.01(A)(1)(b)). Check a sub's BWC certificate of coverage before work starts; a certificate of insurance from a private carrier proves nothing about Ohio comp.

An employer that fails to comply loses the fellow servant, assumption of risk and contributory negligence defenses and can be sued directly by injured workers (4123.77). BWC determines the noncompliance period and assesses premium for it (4123.37), and an injured worker can instead claim benefits that BWC pays and then recovers from the employer (4123.75).

BWC sets its own base rates and experience rating; NCCI's plan does not apply in the monopolistic states (NCCI). Private employers got a 1% rate reduction effective July 1, 2026, worth about $10 million in premium, and on July 30, 2026 the Governor asked the BWC board to approve a dividend projected at $1 billion (Governor's office). Out-of-state employers with Ohio workers need BWC coverage, because Ohio voids private contracts that insure an employer against Ohio comp benefits (4123.82). See Monopolistic state funds: workers' comp in ND, OH, WA and WY and workers' compensation insurance: how it works.

Stop-gap employers' liability

A standard comp policy has two parts: statutory benefits and employers' liability, which defends suits by employees and their families outside the comp system. In the monopolistic states the fund's policy does not include employers' liability, and it is bought separately (Washington DES). The general liability policy excludes employee injury, so without stop-gap an Ohio employer is uninsured for third-party-over actions, consequential injury claims by family members and dual-capacity suits. Stop-gap is usually an endorsement to the general liability policy or a multistate comp policy; match its limits to what your contracts require for employers' liability.

Intentional tort claims are the Ohio-specific issue. An employee can sue outside comp only by proving the employer acted "with the intent to injure another" or with "deliberate intent," but deliberately removing a safety guard or misrepresenting a toxic substance creates a rebuttable presumption of intent (ORC 2745.01). Ohio law also voids contracts that indemnify an employer against damages caused by its own willful act (4123.82). Read exactly how your stop-gap endorsement handles these claims, defense included, before you rely on it. See stop gap coverage in monopolistic states and employers' liability insurance.

Disability and paid leave mandates

Ohio has no state disability insurance program and no paid family and medical leave program. Employers that want to replace income during a non-work illness or family leave do it voluntarily with group short- and long-term disability insurance for employers. Multistate employers should check state disability and paid family leave programs: every mandate in 2026.

Commercial auto requirements

Ohio's financial responsibility minimums are $25,000 per person and $50,000 per accident for bodily injury and $25,000 for property damage (ORC 4509.51). They apply to business vehicles, but contracts commonly require $1 million combined single limit. Interstate for-hire carriers need at least $750,000 under 49 CFR 387.9. See commercial auto insurance: what it covers and what it leaves out and FMCSA insurance requirements and filings for motor carriers.

The business insurance market in Ohio

Severe convective storms and tornadoes are the main catastrophe exposure. FEMA declared a major disaster on May 2, 2024 for tornadoes that began March 14, 2024 (DR-4777). Flood is excluded from standard property forms, and NFIP commercial policies top out at $500,000 building and $500,000 contents (FloodSmart); see Commercial flood insurance: NFIP limits and private options.

The Ohio FAIR Plan Underwriting Association, supported by all insurers licensed to write fire insurance in Ohio, offers commercial fire coverage for property that cannot be placed voluntarily (Ohio FAIR Plan); see FAIR Plans and residual markets for commercial property. Surplus lines brokers collect a 5% tax on gross premiums less return premiums from the insured and pay it annually by March 31 (ORC 3905.36); see surplus lines taxes, stamping fees and diligent search.

Liability law that affects premiums

Ohio uses modified comparative fault: a plaintiff recovers, reduced by their share of fault, only if that fault "was not greater than" the combined fault of everyone else (ORC 2315.33). Noneconomic damages in most tort actions are capped at the greater of $250,000 or three times economic loss, up to $350,000 per plaintiff and $500,000 per occurrence, with exceptions for catastrophic injuries such as permanent and substantial physical deformity or loss of a limb (ORC 2315.18).

Bodily injury and personal property damage suits must be filed within two years (2305.10); written contract claims within six (2305.06).

The construction anti-indemnity statute voids clauses in construction contracts that require a contractor to indemnify the owner or general contractor for injury or damage caused by the indemnitee's own negligence (ORC 2305.31); see additional insured and contractual liability coverage and insured contracts.
