To start an LLC in Ohio, file Articles of Organization (Form 610) with the Ohio Secretary of State and pay a $99 filing fee. You will also need to pick a compliant name, appoint a statutory agent with an Ohio street address, and, after approval, get a federal EIN. Ohio has no publication requirement, no general state business license, and no annual report for domestic LLCs, which keeps the ongoing paperwork light.
Pick a Name That Meets Ohio’s Rules
Your LLC name has to be “distinguishable upon the records” of the Secretary of State. That means it can’t be too similar to an existing Ohio LLC, corporation, limited partnership, or registered trade name. Check availability for free using the Secretary of State’s business name search before you file.1Ohio Legislative Service Commission. Ohio Revised Code Section 1706.07 – Naming of Limited Liability Company
The name also has to end with one of these designators: “limited liability company,” “LLC,” “L.L.C.,” “limited,” “ltd.,” or “ltd.”2Ohio Secretary of State. Limited Liability Company in Ohio A few word categories carry extra restrictions no matter what your business actually does. Words like “bank,” “banker,” “banking,” or “trust” need prior approval from the Superintendent of Financial Institutions. Names that falsely imply a government tie (using “I.R.S.,” for example) are prohibited. Names with profanity or slurs will be rejected outright.3Ohio Secretary of State. Guide to Name Availability
Not ready to file yet? You can reserve a name for 180 days by submitting Form 534B with a $39 fee.4Ohio Secretary of State. Form 534B – Name Reservation, Transfer, Cancellation
Appoint a Statutory Agent
Every Ohio LLC must have a statutory agent to receive lawsuits and legal notices for the company. The agent has to be either an Ohio resident or a business entity with an Ohio business address.5Ohio Legislative Service Commission. Ohio Revised Code Section 1706.09 – Legal Agents of Limited Liability Companies The address must be a physical Ohio street location, not a P.O. box, because the agent needs to be reachable during business hours for hand-delivered documents.
Many owners act as their own statutory agent. You can also hire a commercial service. If the agent later changes address or resigns, file a Statutory Agent Update (Form 521) with the Secretary of State and a $25 fee.6Ohio Secretary of State. Filing Forms and Fee Schedule
File the Articles of Organization
The document that legally creates your LLC is the Articles of Organization, filed on Form 610. This form replaced the older Form 533A in September 2025.6Ohio Secretary of State. Filing Forms and Fee Schedule You’ll need to provide:
- The LLC name exactly as it should appear on state records, including the required designator.
- The name and Ohio street address of your statutory agent, plus the agent’s signed acceptance of the appointment.
- The effective date. Filings take effect when the Secretary of State accepts them, or you can specify a future date up to 90 days later.
The agent’s signature is not optional. The Secretary of State will not process the filing without a written acceptance from the statutory agent.7Ohio Legislative Service Commission. Ohio Revised Code Section 1706.16 – Articles of Organization You can add optional provisions like a stated business purpose or a management structure, but Ohio doesn’t require them.8Ohio Secretary of State. Form 610 – Articles of Organization
Fees and Processing Times
The standard filing fee is $99, whether you submit online or by mail.6Ohio Secretary of State. Filing Forms and Fee Schedule The fastest route is the Ohio Business Central online portal, which lets you file and pay by credit card in one session. If you need faster turnaround than the standard queue, Ohio offers three expedited tiers on top of the $99:
- Level 1, $100 extra: two business days.
- Level 2, $200 extra: one business day.
- Level 3, $300 extra: four business hours.
Expedited processing is worth paying for when a contract signing, loan closing, or licensing deadline hinges on proof that your LLC exists.9Ohio Legislative Service Commission. Ohio Administrative Code Rule 111:1-2-01 – Corporations Expedited Filing
Once your filing is approved, you’ll receive a filing number and a certificate of organization. Keep both; you’ll need them to open a bank account, sign contracts, and prove the LLC’s legal status.
Get an EIN From the IRS
After the state approves your LLC, apply for an Employer Identification Number from the IRS. The EIN is a free nine-digit number that acts like a Social Security number for the business. You’ll need it to file taxes, hire employees, and open a business bank account. The IRS requires state formation before you apply.10Internal Revenue Service. Employer Identification Number
Online applications through the IRS website issue the number immediately during business hours. Single-member LLCs that never plan to hire employees usually still want an EIN because most banks require one to open a commercial account.
Open a Business Bank Account
Keeping business money separate from personal money is central to protecting your personal assets through the LLC structure. Mixing funds weakens that protection. To open a business account, most banks ask for your EIN, your Articles of Organization (or certificate of organization), your operating agreement if you have one, and a government-issued ID.11U.S. Small Business Administration. Open a Business Bank Account
Write an Operating Agreement
Ohio does not require you to file an operating agreement with any government office, but state law recognizes it as the document that controls how your LLC is run.12Ohio Legislative Service Commission. Ohio Revised Code 1706.08 – Limited Liability Company Operating Agreements A written agreement typically covers how profits and losses are split, who manages daily operations, how major decisions are voted on, and what happens when a member leaves or the LLC dissolves.
Skip it and Ohio’s default rules fill the gaps, which may not match what you actually intend. Under the defaults, members share equally in distributions regardless of how much each person contributed, and ordinary business decisions require a majority vote of members. Putting your real arrangement in writing prevents surprises and gives you something to point to when members disagree.
Ohio Taxes Your LLC May Owe
Forming an LLC doesn’t automatically trigger state tax registration. Your activities might.
Commercial Activity Tax
Ohio’s Commercial Activity Tax applies to businesses with more than $6 million in annual Ohio taxable gross receipts. If your LLC stays below that threshold, you are excluded from the CAT entirely. Businesses above the threshold must register with the Ohio Department of Taxation and file CAT returns.13Ohio Department of Taxation. Commercial Activity Tax
Sales Tax and Vendor’s License
If your LLC sells taxable goods or services from a physical location in Ohio, you must get a vendor’s license from the county auditor for each county where you operate. Each location needs its own license. Out-of-state sellers must register for a seller’s use tax license if they had more than $100,000 in Ohio sales or made 200 or more separate Ohio sales in the current or previous year.14Ohio Department of Taxation. Sales and Use Tax
Municipal Income Tax
Many Ohio cities impose their own income tax on businesses operating inside city limits. If your LLC earns income or has employees in one of those municipalities, you’ll typically need to register with the city’s tax administrator and withhold municipal income tax from wages. Rates and rules vary, so check with each city where you operate.
If You Hire Employees
Ohio law requires you to report every new employee and independent contractor to the Ohio New Hire Reporting Center within 20 days of the hire date.15Ohio.gov. New Hire Reporting
Any Ohio LLC with one or more employees must carry workers’ compensation coverage through the Ohio Bureau of Workers’ Compensation. LLC owners can choose whether to cover themselves. If you opt out and get hurt on the job, BWC will not pay benefits for that injury. Elective coverage can be added or canceled at any time through BWC’s application forms.16Ohio Bureau of Workers’ Compensation. href=”https://info.bwc.ohio.gov/for-employers/workers-compensation-coverage/types-of-coverage/elective-coverage” target=”_blank” rel=”noopener”>Elective Coverage
Keeping Your LLC in Good Standing
Ohio is one of the lower-maintenance states for LLCs. Domestic LLCs do not file annual or biennial reports with the Secretary of State.2Ohio Secretary of State. Limited Liability Company in Ohio A few events do trigger filings:
- If your statutory agent resigns or moves, file Form 521 with a $25 fee.
- Any change to the information in your Articles of Organization, including a name change, requires an amendment filed with the Secretary of State.
- When you close the business, file articles of dissolution to formally end the LLC’s existence.
Keep the statutory agent information current at all times. If the Secretary of State can’t reach your agent, your LLC can lose good standing, and you may miss legal notices, including lawsuits against the business.5Ohio Legislative Service Commission. Ohio Revised Code Section 1706.09 – Legal Agents of Limited Liability Companies
How the Liability Shield Holds Up
The main reason to form an LLC is the personal liability protection. Under Ohio law, a member is not personally responsible for the debts or legal obligations of the company simply because they are a member, and this covers both contract claims and lawsuits. Ohio also states that failing to observe corporate formalities such as regular meetings or detailed minutes is not, by itself, grounds for holding members personally liable.17Ohio Legislative Service Commission. Ohio Revised Code Section 1706.26 – Liabilities of Limited Liability Company Members
The shield has limits. A court can disregard the LLC structure if members commingle personal and business funds, use the LLC to commit fraud, or treat the company as an extension of personal finances rather than a separate entity. A dedicated bank account, clean records, and a written operating agreement all help keep the protection intact.
