Ohio private employer rate cut

Ohio BWC 1% average cut, effective July 1, 2026, reported by WorkCompWire, July 2026

Ohio is one of the few states where you cannot shop for workers’ comp: the Ohio Bureau of Workers’ Compensation (BWC) sets the premium from its own classifications, rules and rates under Ohio Revised Code 4123.35. BWC cut private employer rates by an average of 1% on July 1, 2026, worth about $10 million a year, and says private rates are 50% lower than in 2019 and at their lowest average level in over 65 years. No private insurer publishes Ohio medians, so the Insureon figures above are national: a $54 monthly median and roughly $250 to $5,700 a year, drawn mostly from states with private markets. Treat them as a rough guide only. BWC says your own premium depends on the expected claim costs in your industry, your recent claims and the BWC programs you join.

Ohio

What’s different in Ohio

You cannot buy Ohio comp from a private insurer

Ohio Revised Code 4123.82 voids any contract that insures an employer against paying Ohio workers’ comp benefits, and no license to sell one can be issued. Your coverage comes from the BWC state fund unless BWC approves you to self-insure.

Uninsured employers lose their best defenses

Under Ohio Revised Code 4123.77, a private employer without coverage loses the protections of the workers’ comp law and can be sued for an employee’s injury. It cannot argue the fellow servant rule, assumption of risk or contributory negligence.

BWC pays the worker, then comes after you

Ohio Revised Code 4123.75 lets an injured employee of an uninsured employer claim from BWC’s surplus fund. BWC then recovers what it paid from the employer, which must pay the award or post a bond, and the worker can still sue.

Intentional tort suits sit outside the system

Employees can sue an Ohio employer for an intentional tort under Ohio Revised Code 2745.01. Deliberately removing a safety guard on equipment creates a legal presumption of intent to injure if an injury results directly from it.

Your Ohio policy stops at the state line

BWC warns that some states require coverage for employees working there for any amount of time. Crews, drivers and installers who work outside Ohio may need BWC’s Other States Coverage or a private policy for that state.

Premium is due before the year starts

Ohio Revised Code 4123.35 requires private employers to pay the estimated annual premium in June, before the July 1 policy year. After your payroll report, BWC adjusts for actual payroll and any balance is due immediately.

BWC state fund policy

Pays medical care and lost wages for work injuries and occupational disease for your Ohio employees. It is the only way most Ohio employers can meet the law.

Out-of-state workers’ comp

For employees who work outside Ohio. BWC offers Other States Coverage, and Ohio Revised Code 4123.82 lets private insurers write workers’ comp for other states.

Stop gap employers liability

Private cover, often added to a general liability policy, for injury lawsuits by employees or third parties that a BWC policy does not handle. Check the terms closely: Ohio Revised Code 4123.82 voids insurance for damages caused by an employer’s willful act.

Longshore and harbor workers’ coverage

Federal USL&H coverage for maritime workers on Ohio’s waterfronts, which BWC lists among its coverage types alongside regular state fund coverage.

Self-insurance

Larger employers can apply to BWC to pay their own claims. Under Ohio Revised Code 4123.82, they may buy excess insurance for losses above at least $50,000 from any one event.

Umbrella or excess

Adds limits above stop gap and general liability when a contract or the size of your workforce calls for more than your primary limit.

Rules

Ohio requirements

Ohio requires coverage from the first employee and runs its own state fund. The rules below come from Ohio Revised Code chapter 4123 and BWC. Check your exact situation with BWC.

Requirement	Applies to	What it means
Coverage from the first employee	Every private and public employer with one or more employees	Ohio Revised Code chapter 4123 makes these employers subject to the workers’ comp law, with coverage bought from BWC.
State fund only	All Ohio employers that do not self-insure	Ohio Revised Code 4123.82 voids private contracts that insure Ohio workers’ comp benefits.
Self-insurance	Employers approved by BWC	Self-insurers pay their own claims and may buy excess cover for losses above at least $50,000 per event, per Ohio Revised Code 4123.82.
Advance premium and payroll true-up	Private employers	Estimated annual premium is due in June before the July 1 policy year. After the payroll report, BWC adjusts for actual payroll and any balance is due immediately, per Ohio Revised Code 4123.35.

Consequences of going uninsured	Private employers without coverage	They can be sued without common law defenses (Ohio Revised Code 4123.77) and must repay BWC for claims it pays their workers (Ohio Revised Code 4123.75).
Buying a business	Employers that buy all or part of another business	BWC requires you to notify it of the purchase.
Work in other states	Ohio employers with employees working outside Ohio	BWC notes some states require coverage for any time worked there; Other States Coverage is available from BWC.

Pay less

How to lower the cost

Put every employee in the right BWC classification: premium is set by classification under Ohio Revised Code 4123.35, so a clerical worker coded as field labor costs you more.
Estimate payroll realistically. BWC trues up to actual payroll after the policy year, and any shortfall is due at once.
Ask BWC which of its programs fit your business; BWC says participation in its programs is one of the factors in your premium.
Report and manage claims promptly, since your recent claims history feeds into your rate.
Keep safety guards on machines. Removing one deliberately invites an intentional tort suit under Ohio Revised Code 2745.01 that your BWC policy will not answer.

Common questions

Workers’ comp insurance in Ohio: questions

Can I buy Ohio workers’ comp from a private insurance company?

No. Ohio Revised Code 4123.82 voids private contracts that insure Ohio workers’ comp benefits, so coverage comes from BWC unless BWC approves you to self-insure. Private insurers can still sell stop gap employers liability and workers’ comp for other states.

When is Ohio workers’ comp premium due?

Private employers pay the estimated annual premium in June, before the policy year starts on July 1, under Ohio Revised Code 4123.35. After you file your payroll report, BWC adjusts the premium to actual payroll.

What happens if an employee is hurt while I have no coverage?

The employee can claim from BWC, which pays from its surplus fund and then recovers the money from you under Ohio Revised Code 4123.75. The employee can also sue you, and Ohio Revised Code 4123.77 strips away your common law defenses.

Does my Ohio policy cover employees working in another state?

Not automatically. BWC warns that some states require coverage for any time worked there and offers Other States Coverage, including a supplemental application for trucking companies.

Can an employee sue me even if I have BWC coverage?

Yes, for an employer intentional tort under Ohio Revised Code 2745.01, which requires proof of intent to injure or deliberate intent. Deliberately removing an equipment safety guard creates a presumption of that intent.

Did Ohio workers’ comp rates go down in 2026?

Yes. BWC cut private employer rates by an average of 1% on July 1, 2026, saving about $10 million, after a 1% cut for public employers on January 1, 2026. Your own premium can still rise if your claims or payroll grow.

Are religious exemptions allowed in Ohio?

Yes. BWC says employers and employees may apply for a workers’ comp exemption on religious grounds. Approval is not automatic, so apply through BWC before relying on it.
