Choosing a PEO in Ohio
Ohio's minimum wage structure has an important distinction: employers with annual gross receipts of $405,000 or more must pay a minimum wage of $11.00 per hour, while smaller employers below that threshold default to the federal minimum of $7.25 per hour. Ohio's minimum wage is adjusted annually based on a set formula, so employers should verify the current rate each January. Ohio has no state income tax advantages to offer, and compliance requirements track closely with federal standards in most areas.
One of the most distinctive aspects of Ohio's HR landscape is its workers' compensation system. Ohio is one of only a handful of states with a monopolistic state insurance fund — meaning private employers must purchase workers' comp through the Ohio Bureau of Workers' Compensation (BWC) or qualify as a self-insured employer. Private insurance carriers cannot provide workers' comp in Ohio. This makes Ohio workers' comp administration unique and is an area where an experienced PEO can provide significant expertise and administrative relief.
Ohio follows the federal WARN Act, requiring 60 days advance notice for mass layoffs affecting 50 or more employees. Ohio is not a right-to-work state, meaning union security agreements are permitted — relevant for businesses in Ohio's significant manufacturing, automotive, and steel sectors. Ohio has no statewide paid sick leave law, though the federal FMLA applies to employers with 50 or more employees.
Ohio's economy is anchored by manufacturing, healthcare, financial services, and a growing technology sector, particularly in Columbus. Businesses in these industries face distinct HR challenges around workforce management, compliance, and benefits access. A PEO with Ohio expertise — particularly one experienced in BWC administration and the state's unique workers' comp system — can provide significant value.

Frequently Asked Questions
What is the minimum wage in Ohio in 2026?
Ohio's minimum wage is $11.00 per hour for employers with annual gross receipts of $405,000 or more. Employers with annual gross receipts below $405,000 must pay the federal minimum wage of $7.25 per hour. Ohio adjusts its minimum wage annually based on a set formula tied to inflation, so employers should verify the current rate each January.
How does workers' compensation work in Ohio?
Ohio has a monopolistic workers' compensation system — private employers must purchase coverage through the Ohio Bureau of Workers' Compensation (BWC) or qualify as a state-approved self-insured employer. Private insurance carriers cannot provide workers' comp in Ohio. A PEO with Ohio experience understands the BWC system and can manage the administrative complexity of Ohio workers' comp on behalf of client businesses.
Does Ohio have a paid sick leave law?
Ohio has no statewide paid sick leave requirement. Employees may be entitled to unpaid leave under the federal Family and Medical Leave Act if their employer has 50 or more employees. Employers that want to offer paid sick leave do so voluntarily or through a PEO-administered benefits program.
Is Ohio a right-to-work state?
No. Ohio is not a right-to-work state, meaning union security agreements are permitted and employees can be required to pay union dues or agency fees as a condition of employment in unionized workplaces. This is relevant for businesses in Ohio's significant manufacturing, automotive, and industrial sectors where union presence is more common.
