To start an LLC in Ohio, you file articles of organization (Form 610) with the Ohio Secretary of State, pay a $99 filing fee, and name a statutory agent with an Ohio street address. Standard processing runs three to seven business days, and expedited options are available. After the state approves the filing, you handle a few federal and internal items — an EIN from the IRS, an operating agreement, and any licenses your industry or city requires.
Ohio is one of the friendlier states for LLC owners. There is no annual report, no annual state fee, and the main business tax now only applies to companies with more than $6 million in gross receipts.1Ohio Department of Taxation. Commercial Activity Tax (CAT)
Pick a Name That Ohio Will Accept
Your LLC name must include one of the required legal designators: “limited liability company,” “LLC,” “L.L.C.,” “limited,” “ltd.,” or “ltd.”2Ohio Legislative Service Commission. Ohio Revised Code Chapter 1706 – Section 1706.07 Most owners put “LLC” at the end.
The name also has to be distinguishable from every other entity already on file with the Secretary of State, including corporations, limited partnerships, LLPs, and registered trade names. Check availability through the business name search at ohiosos.gov before you file.2Ohio Legislative Service Commission. Ohio Revised Code Chapter 1706 – Section 1706.07
“Distinguishable” is not the same as “totally different.” The state may approve a name close to an existing one, but a confusingly similar name can still draw a trademark dispute from the other business later. Worth thinking about before you print anything.
Appoint a Statutory Agent
Every Ohio LLC must continuously maintain a statutory agent in the state to receive lawsuits and official notices. Ohio calls this a statutory agent; other states call the same role a registered agent.3Ohio Legislative Service Commission. Ohio Revised Code Chapter 1706 – Section 1706.09
The agent must be either an Ohio resident or a business entity with a physical office in Ohio. The address on file must be a street address where someone is available during normal business hours. A P.O. box does not qualify.3Ohio Legislative Service Commission. Ohio Revised Code Chapter 1706 – Section 1706.09
You can be your own agent if you live in Ohio, which costs nothing but puts your home address into the public record and ties you to that address during business hours. Commercial statutory agent services typically charge $50 to $300 per year. If the agent or their address ever changes, update the Secretary of State promptly.
File the Articles of Organization
The articles of organization are the document that legally creates your LLC. In Ohio, that is Form 610, filed with the Secretary of State. The required contents are minimal:4Ohio Legislative Service Commission. Ohio Revised Code Chapter 1706 – Section 1706.16
- The full LLC name, including the legal designator.
- The name and street address of your statutory agent, with the agent’s signed acceptance.
- Any optional provisions you want to include (most people leave this blank).
The filing fee is $99.5Ohio Secretary of State. Business Filing Forms and Fee Schedule File online through Ohio Business Central at ohiobusinesscentral.gov, or mail the paper form. Standard processing runs three to seven business days either way.

Handle the Post-Formation Basics
Get an EIN From the IRS
An Employer Identification Number is the nine-digit federal tax ID you need to open a business bank account, file taxes, and hire employees. Multi-member LLCs always need one. Single-member LLCs can technically use the owner’s Social Security number, but an EIN is free and keeps your SSN off business paperwork.
Apply at irs.gov and the number is issued immediately. The IRS recommends forming the LLC with the state first.7Internal Revenue Service. Get an Employer Identification Number
Write an Operating Agreement
Ohio does not require you to file an operating agreement with the state, but the statute gives the document real legal weight. Under Ohio law, the operating agreement governs relationships among members and between members and the LLC. Where the agreement is silent, the default rules in Chapter 1706 of the Ohio Revised Code fill in.8Ohio Legislative Service Commission. Ohio Revised Code Section 1706.08 – Limited Liability Company Operating Agreements
Ohio’s version is unusually flexible. A written agreement can expand, restrict, or eliminate fiduciary duties among members and managers, though it cannot eliminate the implied duty of good faith and fair dealing. It can also set consequences for members who fail to meet obligations, including reducing their interest or forcing a sale of their membership stake.8Ohio Legislative Service Commission. Ohio Revised Code Section 1706.08 – Limited Liability Company Operating Agreements
Single-member LLCs benefit from one too. Banks often ask for it when opening a business account, and it reinforces the legal separation between you and the company.
Check Licenses and Permits
Ohio has no general state business license, but industry and location can trigger specific requirements. Businesses selling physical goods typically need a vendor’s license from the Ohio Department of Taxation. Regulated professions like contractors and healthcare providers need state-level licensing. Your city or county may require a local business registration or zoning permit. Check with your local government and any applicable state licensing board before opening.
Choose Your Federal Tax Classification
This is the step most new owners overlook. The IRS has no dedicated tax category for LLCs. It assigns a default based on your number of members, and you can elect a different one if it fits your situation.9Internal Revenue Service. LLC Filing as a Corporation or Partnership
- A single-member LLC is a “disregarded entity” by default. You report business income and expenses on your personal return, typically on Schedule C.
- A multi-member LLC is taxed as a partnership by default. The LLC files Form 1065, and each member reports their share on their personal return.
Either type can elect to be taxed as a C corporation using Form 8832, or as an S corporation using Form 2553.10Internal Revenue Service. About Form 8832, Entity Classification Election An S-corp election can lower self-employment tax once the business is profitable enough to support paying the owner a reasonable salary, but it adds payroll obligations and complexity. For most brand-new LLCs, the default classification is fine. Revisit the question after a full year of revenue.
Ohio Taxes You Should Know
Commercial Activity Tax
The Commercial Activity Tax applies to all business structures, including LLCs. Starting in 2025, only businesses with more than $6 million in annual Ohio taxable gross receipts must register and pay. The rate is 0.26% on gross receipts above the $6 million exclusion. If your LLC crosses the threshold, you must register with the Ohio Department of Taxation within 30 days.1Ohio Department of Taxation. Commercial Activity Tax (CAT)
The threshold was raised from $150,000 to $6 million over 2024 and 2025, so the vast majority of small Ohio businesses now owe nothing.
Income and Self-Employment Tax
Ohio has a personal income tax, and LLC members pay it on their share of profits. The LLC itself does not pay a separate state income tax outside of the CAT. Federally, LLC members who actively participate in the business owe self-employment tax of 15.3% on their share of profits, covering Social Security and Medicare. This is the tax that surprises first-time owners most, because it sits on top of income tax with no employer paying half.
Sales Tax and Employer Obligations
If your LLC sells taxable goods or certain services, you collect and remit Ohio sales tax. If you hire employees, you withhold Ohio income tax and contribute to unemployment insurance. Ohio also requires workers’ compensation coverage for any employer with one or more employees, administered through the Ohio Bureau of Workers’ Compensation.
Ongoing Compliance in Ohio
Ohio is among the easiest states for LLC upkeep. There is no annual report and no annual fee to the Secretary of State. Most states charge $50 to $300 per year for annual filings, so this is a real advantage.
Ongoing does not mean nothing. Keep these on your radar:
- Update your statutory agent with the Secretary of State whenever the name or address changes. Letting this lapse can mean missing a lawsuit and losing by default.
- File your federal and Ohio income tax returns annually. Sales tax and payroll filings may be monthly or quarterly.
- Keep your operating agreement, amendments, financial statements, and records of major decisions. Clean records help defend your personal liability shield if anyone challenges whether the LLC has been run as a real entity.
- Watch the beneficial ownership rules. As of March 2025, FinCEN exempted all U.S.-created companies from the Corporate Transparency Act’s beneficial ownership reporting requirement; only foreign entities registered to do business in the U.S. currently have to file. Congress could change this.11Financial Crimes Enforcement Network (FinCEN). FinCEN Removes Beneficial Ownership Reporting Requirements for U.S. Companies and U.S. Persons
The real ongoing work for an Ohio LLC is not state filings. It is staying current on taxes, keeping clean books, and running the company as a distinct legal entity so the liability protection holds up if it is ever tested.
