Ohio is a monopolistic state, so required coverage comes from the state, not a private insurer. How monopolistic workers comp states work
When coverage is required
Ohio generally requires workers' comp once you have one employee, full-time or part-time. Most employers get coverage through the Ohio Bureau of Workers' Compensation (BWC). Some larger employers can get approval to self-insure. Do not assume a private policy from another state meets Ohio's rule.
Owners, contractors, and exceptions
Household workers, working owners, corporate officers, and short jobs outside Ohio each have their own rules. Use BWC's application guide to review your real business setup. Report ownership changes and business purchases as BWC directs. A policy in the old owner's name does not automatically move to you when you buy a business.
If an employee is injured
Workers should tell you quickly and tell their doctor the injury happened at work. Help give accurate information for the BWC claim and keep an eye on the claim status. Keep the accident description, wages, and work limits from the doctor handy. Answer requests from BWC, or from your claims handler if you self-insure, so decisions are based on full information.
Operating without coverage
If your BWC coverage lapses or you never got it, a worker hurt during that time can sue you or file a claim with BWC. If BWC approves the claim, you must pay BWC back every dollar. BWC can also put liens on your property for unpaid premium and claim costs. When you restart coverage, it begins when BWC gets your payment. It does not go back in time. File payroll reports and pay premium on time to avoid a lapse.
How to arrange coverage
Apply through BWC, using the U-3 application if it applies to you, or confirm you are approved to self-insure. Keep your payroll classes and reports accurate, and complete the required yearly payroll true-up. For work outside Ohio, ask separately about the right coverage. Being enrolled with BWC does not cover you in other states.
Benefits and return-to-work planning
A work injury can lead to medical care, time off work, a lasting disability, or benefits for family members if a worker dies. Who qualifies, waiting periods, how wages are figured, and benefit limits all depend on state law and the facts of the claim. Ask your insurer which benefits it is looking at and what records it needs. Go by the doctor's work limits, not your own guess about what the worker can do. If you can offer lighter work, describe the duties and hours clearly and plan it with the doctor and your insurer.
Preparing an accurate cost estimate
Gather payroll by job and location, a description of each type of work, details on working owners, subcontractor records, and your past claims. Ask the insurer to confirm your job classes, how the rate is figured, any experience modifier, the minimum premium, fees, and audit terms. This site's calculator uses a base rate that you enter. It does not give a state-approved rate or a real quote. Compare offers using the same numbers, and track staff and work changes during the year so the final audit is easier.
Forms, posters, and notices
These links go straight to Ohio’s official forms. Your insurer can often send a poster with your policy details already filled in.
Weekly benefit limits
These limits cap the wage replacement checks an injured worker can get. Medical care is paid separately. Limits change every year, so check the source for the latest figures.
- Waiting period
- The first 7 days are paid only after the worker has been off for 14 days in a row.
Temporary total pay is 72% of the full weekly wage for the first 12 weeks, then two thirds of the average weekly wage, up to a yearly maximum.
Check a contractor’s coverage
Ohio BWC is the state's insurer for most employers and offers a search to see if an employer has coverage.
Owner exemptions and elections
Some owners who are not covered automatically, such as sole owners and partners, can buy elective coverage through BWC.
Frequently asked questions
Is workers' comp required in Ohio?
Yes once a business has one employee, full-time or part-time. Coverage comes from the Ohio Bureau of Workers' Compensation (BWC) unless the employer is approved to self-insure.
Do business owners need workers' comp in Ohio?
Owners, corporate officers, and domestic employment have specific rules in BWC's application process. Report ownership changes and business purchases to BWC, because a policy does not automatically transfer to a new owner.
How long does an employee have to report a work injury in Ohio?
Employees should tell the employer quickly and tell the doctor the injury is work-related. Claims are filed with BWC (or the self-insured employer's administrator), and the employer should answer BWC's requests so the claim is decided on complete information.
What happens if a Ohio business doesn't have workers' comp?
If coverage lapses, an injured worker can sue the employer or file a claim with BWC. If BWC pays the claim, the employer must reimburse it dollar for dollar, and BWC can file liens for unpaid premium and claim costs.
How do I get workers' comp insurance in Ohio?
Apply to BWC (Form U-3 for most new employers) or qualify for self-insurance. Private insurers cannot sell Ohio workers' compensation, so out-of-state work needs separate coverage.
How much does workers' comp cost in Ohio?
Ohio premiums are set by the Bureau of Workers' Compensation, using its own job classes and rates instead of quotes from private insurers. Ask the agency for your job class and rate, then use your payroll to estimate the cost.
