Ohio Business Insurance Requirements: What Is Mandatory and What You Should Carry

Ohio does not require most businesses to carry general liability insurance, and it does not issue a general state business license. The state's mandatory insurance list is shorter than many owners expect: workers' compensation for any employer with at least one employee, motor vehicle liability for registered vehicles, and general liability for a few specific situations. Most of the rest of your coverage comes from contracts, leases, lenders, and license boards.

This guide separates what Ohio makes mandatory from what you should carry anyway, so you can plan coverage before you form the business rather than after the first client asks for a certificate of insurance. Every trade has its own exposure, so treat this as a starting map for your ohio business insurance planning, not a finished plan.

Informational content, not legal or tax advice. This guide explains Ohio's general insurance rules as of October 2026. It does not account for your industry, contracts, or location, and it is not legal, tax, or insurance advice. Talk to a licensed Ohio insurance agent, an attorney, or a CPA before you buy, change, or drop coverage.

The short answer: what Ohio requires

The table below is the quick reference. The sections that follow explain the exceptions and the decisions behind them.

Coverage	Required in Ohio?	Who it applies to	Source
Workers' compensation	Yes	Any employer with one or more employees, including part-time	Ohio BWC state fund (ORC 4123.01 and 4123.35)
Motor vehicle liability	Yes	Registered motor vehicles	Financial responsibility minimums (ORC 4509.01)
Unemployment insurance	Yes, as a payroll tax	Employers with employees	ODJFS payroll tax, not an insurance policy
General liability	Only in specific cases	Home construction service suppliers ($250,000 minimum, ORC 4722.01), plus some licensed trades, bonds, leases, and contracts	Statute, license board rules, and contracts
Other coverage	Depends on your agreements	Landlords, clients, and lenders	The contracts and loan documents you sign

Workers' compensation: the one policy you cannot buy privately

Ohio runs a monopolistic state workers' compensation system. Employers do not buy workers' compensation from a private insurance company. Coverage comes from the Ohio Bureau of Workers' Compensation (BWC), which operates the state fund. Under Ohio Revised Code (ORC) 4123.01 and 4123.35, any employer with one or more employees must be covered through BWC, and that includes part-time employees.

A few practical points follow from that rule:

• Part-time counts. One part-time employee on your payroll triggers the requirement. Hours and pay level do not change that.
• Sole proprietors with no employees are not required to cover themselves. The same is true for LLC members who have no employees.
• Classify every worker carefully. If you hire help, decide whether each person is an employee or an independent contractor, and confirm the classification with BWC before you rely on it. Misclassifying a worker is a common way an uninsured injury ends up on a small business.
• Premiums depend on payroll and risk classification. BWC sets the rates for your classification. Confirm your classification and current rates with BWC before you make your first hire.

Do not treat workers' compensation as optional, and do not look for a private carrier to write it. If an injury claim falls outside the state fund's coverage, the business carries that cost.

Unemployment insurance is a payroll tax, not a policy

Once you have employees, you also register with the Ohio Department of Job and Family Services (ODJFS) for unemployment compensation. This is a payroll tax that funds state unemployment benefits. You do not buy it from an insurer, and it does not replace workers' compensation. Keep your payroll records current, and confirm your employer account and contribution rates with ODJFS.

Motor vehicle liability for registered vehicles

Under ORC 4509.01, every registered motor vehicle must carry liability insurance that meets Ohio's financial responsibility minimums: $25,000 per person and $50,000 per accident for bodily injury, plus $25,000 for property damage. Those are legal minimums, and they are low for a business vehicle. A van that carries crew, tools, or client property can generate claims well above those limits.

Personal auto policies often exclude or limit business use. If a vehicle is used for deliveries, client visits, or hauling materials, ask your agent whether you need a commercial auto policy. Insure the vehicle for how it is actually used, not how you hope it will be used.

General liability: required in a few cases, expected in many more

Ohio does not require general liability insurance for businesses generally. General liability covers third-party claims for bodily injury, property damage, and certain advertising injuries. Three situations change the answer.

Home construction service suppliers

ORC 4722.01 requires home construction service suppliers to carry at least $250,000 in general liability coverage. If your business does home construction work, check whether your services fall within that definition before you assume you are exempt. When the answer is unclear, confirm it with an attorney before you bid a job.

Licenses and license boards

Some occupational licenses require proof of insurance or a bond as a condition of licensure. Those rules come from the licensing board, not from a general Ohio business rule. Contractors should check the rules of the Ohio Construction Industry Licensing Board (OCILB), along with the board for any other trade they license, before filing an application or renewal. Limits and the form of proof can vary by board, so confirm the specifics with the board itself rather than relying on a summary.

Bonds, leases, and contracts

Surety bonds, commercial leases, and client contracts frequently require general liability coverage with stated limits. Read the insurance section of every agreement you sign. Note the required limits, any additional insured requirement, and the deadline for delivering a certificate of insurance.

Contract-driven coverage: landlords, clients, and lenders

For most Ohio businesses, the insurance that actually gets bought is driven by someone else's requirements. Three groups push coverage most often:

• Landlords usually require general liability with the landlord named as an additional insured, and some require property coverage for improvements you make to the space.
• Clients often require a certificate of insurance before work starts. Some want higher limits than you carry or want their name added to your policy.
• Lenders require property coverage on financed equipment, vehicles, or real estate, with the lender listed as loss payee.

Get the required limits in writing before you sign. If a client requires higher limits than you carry, ask your agent whether raising your limits or adding an umbrella policy closes the gap. Do not sign a contract you cannot meet.

Licensed trades and local rules

Ohio issues no single general state business license, and there is no statewide general contractor license. Counties do not issue a business license either. The near universal registration is the vendor's license for taxable sales, which the county auditor issues under a state statute, with a $50 application fee for a county vendor's license as of April 9, 2025. Cities and villages tax business net profit under their own rates, so check your municipality for local requirements. For the rules that apply to your specific trade, check the relevant board's website.

What to carry even when Ohio does not require it

These are the coverages most small businesses should price out, whatever the state requires. Ask your agent for written quotes on each, and compare what the policies cover, not only the premium. This guide does not list premium amounts because a reliable figure depends on your trade, revenue, and claims history.

• General liability. Covers third-party injury and property damage claims arising from your operations. Most client contracts expect it.
• Professional liability (errors and omissions). Covers claims that your advice or work was faulty. General liability usually does not cover those claims, so consultants, designers, and other service providers should ask about it by name.
• Commercial property. Covers your equipment, tools, inventory, and furnishings. A landlord's policy almost never covers your own property.
• Business owner's policy (BOP). Many small businesses bundle general liability and commercial property into one policy. Ask whether a BOP fits your exposure.
• Commercial umbrella. Adds limits above your general liability, auto, and other underlying policies. Ask your agent whether an umbrella is a cheaper way to reach the limits your contracts demand.

Setup checklist

1. Form the entity first. Articles of Organization for a domestic LLC (Form 610) cost $99 and are filed with the Ohio Secretary of State. A for-profit corporation files Initial Articles of Incorporation (Form 532A) for the same $99. Check name availability in the Ohio Business Search at https://businesssearch.ohiosos.gov/. A name reservation costs $39 and holds the name for 180 days.
2. Register with BWC and ODJFS before your first payroll. Any employee, including a part-time employee, triggers both.
3. Review every contract, lease, bond, and license application for insurance requirements, and write down each required limit.
4. Get written quotes for general liability, professional liability, and property coverage, and ask whether a business owner's policy or an umbrella fits.
5. Insure vehicles for business use and confirm the policy covers the drivers you actually use.
6. Calendar your renewals. Review your coverage and your contract requirements once a year, and again whenever you add employees, vehicles, or a new client type.

If you operate under a name other than your legal name, register a trade name with the Ohio Secretary of State for $39. Trade names are registered with the Secretary of State, not the county.
