Is Workers’ Comp Required in Ohio?
Yes, workers compensation insurance is required in Ohio for all employers with one or more employees, with no minimum threshold — coverage must be obtained before hiring the first employee
Ohio Workers’ Comp Requirements at a Glance
Here are the exact Ohio workers compensation requirements every employer should know:
| Employees that trigger the mandate | 1 |
| Which workers count | All employees count toward the threshold including full-time, part-time, temporary, and seasonal workers; there is no distinction based on hours worked or employment duration |
| Who is exempt | Sole proprietors with no employees, partnerships with no employees, LLC members acting as sole proprietors or partners with no employees, family farm corporate officers with no employees, sole-owner corporations with no other employees, ministers and clergy of religious organizations, and domestic workers (housekeepers, babysitters, gardeners, nannies) who earn less than 160 per calendar quarter — once a domestic worker earns 160 or more in a quarter coverage becomes mandatory; notably Ohio does NOT exempt agricultural or farm workers unlike many other states |
| Owners & officers | Corporate officers are automatically considered employees under Ohio law and included in coverage by default, but may elect to exclude themselves by filing the proper BWC exclusion form; sole proprietors, partners, and LLC members are not automatically covered but may elect to include themselves through voluntary elective coverage with BWC |
| Penalty for going without | Employers who fail to obtain or maintain coverage face a first-degree misdemeanor criminal charge; if unpaid premiums or assessments total 1000 to 7499 with intent to defraud the charge escalates to a fifth-degree felony with possible incarceration; late premium payments incur a 30 fine plus up to 15 percent of the premium due; BWC may assess an additional 1 percent of the premium due; non-complying employers lose all statutory protections and become personally liable for all employee injury claims, and employees may sue the employer directly in civil court; liens may be placed on business property; each corporate officer including the president, secretary, general manager, or managing agent can be held individually responsible under ORC 4123.35 |
| Monopolistic state? | Yes — must buy from the state fund |
| State fund | Ohio has a monopolistic state fund called the Ohio State Insurance Fund administered by the Ohio Bureau of Workers Compensation (BWC), the largest state workers compensation fund in the nation with over 19 billion in assets |
How to Get Workers’ Comp Coverage in Ohio
Employers must register directly with the Ohio Bureau of Workers Compensation (BWC) and obtain coverage through the Ohio State Insurance Fund before hiring their first employee; large employers may apply through BWC to become self-insured, which requires five years of certified financial statements, authorization to do business in Ohio, two years of experience with the State Insurance Fund, and demonstrated financial stability
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. That trade-off is the practical heart of the Ohio workers compensation requirements: the coverage exists to keep one bad injury from sinking both the worker and the business.
Employees vs. Independent Contractors in Ohio
The most common way owners get the Ohio workers compensation 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: Ohio is one of only four monopolistic states in the US (along with North Dakota, Washington, and Wyoming) meaning all coverage must go through the state fund with no private market; self-insurance is available but only through BWC approval not through private insurers; corporate officers are employees by default but can elect exclusion; Ohio has no agricultural worker exemption unlike many states;
the domestic worker threshold of 160 per quarter is notably low; family farm corporate officers have a specific carve-out exemption; individual corporate officers can be held personally responsible for noncompliance under ORC 4123.35
Understanding Ohio Workers Compensation Requirements
The Ohio workers compensation requirements exist to make sure injured employees get medical care and lost wages without having to sue. For most owners, the Ohio workers compensation requirements come down to one number: the employee count that triggers the mandate, shown in the table above.
