Ohio at a Glance
| Required at | 1 employee(s) |
| Which workers count | Ohio counts every person who works for an employer regularly in the same business, including full-time, part-time and seasonal workers. The law doesn’t distinguish between them. There is no separate construction rule because every industry is covered from the first employee. The one dollar-based trigger is for domestic household workers: coverage is required if a household employer pays a worker 160 or more in a calendar quarter or in any 13 consecutive weeks. |
| Monopolistic state? | Yes — must buy from the state fund |

| Owners & officers | In Ohio these owners are excluded by default and opt in, rather than opting out. Sole proprietors, partners (one or all of them), qualifying LLC members, family farm corporate officers and individuals incorporated with no employees can choose to buy elective coverage from the BWC (form U-3 or U-3S). Anyone who elects coverage must report income or payroll of at least 419 a week (21788 a year) and no more than 1256 a week (65312 a year). If they report less than the minimum, the coverage is cancelled. The BWC can update these payroll figures, so confirm them before relying on them. |
| Monopolistic state? | Yes — must buy from the state fund |
| State fund | YES. The Ohio State Insurance Fund, run by the Ohio Bureau of Workers’ Compensation (BWC). It is the only source of coverage, except for employers the BWC approves to self-insure. |
How to Get Workers’ Comp Coverage in Ohio
Apply directly to the Ohio BWC using form U-3 (online or on paper) with a 120 non-refundable application fee. The policy takes effect when the BWC receives the completed application and fee. The BWC then sends a Notice of Estimated Annual Premium based on the 12-month payroll estimate. Larger employers that meet the BWC’s financial standards can apply to self-insure.
Ohio does not use private carriers, an assigned-risk pool or NCCI for state coverage.
What Workers’ Comp Covers in Ohio
Workers’ compensation is a no-fault system: an injured employee gets benefits without having to prove the employer did anything wrong, and in exchange gives up the right to sue for most workplace injuries. A typical Ohio policy pays for medical treatment tied to a work injury, part of the wages lost while the worker recovers, longer-term disability benefits if the injury is permanent, and death benefits to a family.
It also includes employers-liability coverage, which protects the business if an injury still leads to a lawsuit.
Employees vs. Independent Contractors in Ohio
The most common way employers get the Ohio workers comp requirements wrong is by assuming a worker is an “independent contractor” who does not count. State agencies look at how the work is actually controlled, not the label on a 1099. If Ohio decides a contractor was really an employee, the business can owe back premiums and penalties as if coverage should have been in place all along.
When you are close to the employee threshold, confirm each worker’s status with your state board before you decide you are exempt.
Other Ohio workers’-comp rules: Private insurers cannot sell Ohio workers’ comp coverage, so employers with workers who travel or work in other states may need separate out-of-state coverage. A lapse begins automatically if the BWC doesn’t receive the payroll report and premium on time. While coverage is lapsed, an injured worker can choose to sue the employer for all damages or file a claim with the BWC.
The BWC offers lapse and penalty forgiveness (form U-59). Employers should confirm current premium, fee and payroll figures with the Ohio BWC, and anyone with a specific situation should talk to a licensed Ohio attorney.

Understanding Ohio Workers Comp Requirements
The Ohio workers comp requirements exist so injured employees get care and lost wages without having to sue. For most employers, the Ohio workers comp requirements come down to one number: the employee count that triggers the mandate, shown in the table above. Once you hit that count, Ohio workers comp requirements apply whether you planned for them or not, and the penalty for going without is real.
If any part of the Ohio workers comp requirements is unclear, your state board can confirm the threshold, the exemptions, and how to get covered.
