Forming an LLC in Ohio takes one filing with the Secretary of State, a $99 fee, and a handful of decisions you make around that filing. The document that creates the company is the Articles of Organization (Form 610). Before you submit it, you need a compliant name and a statutory agent. After it’s approved, you get a federal tax ID, put an operating agreement in place, and open a business bank account. Ohio doesn’t require annual or biennial reports, so ongoing upkeep is lighter than in most states.
Pick a Name That Meets Ohio’s Rules
Your LLC’s name has to include a designator that signals its status. Ohio accepts “limited liability company,” “L.L.C.,” “LLC,” “limited,” “ltd.,” or “ltd.”1Ohio Legislative Service Commission. Ohio Revised Code 1706.07 – Naming of Limited Liability Company The name also has to be distinguishable from every entity already on file with the Secretary of State. Small tweaks like adding “the” or changing punctuation generally aren’t enough; “Clearview LLC” and “Clear View LLC” would likely be treated as too similar.
Search the Secretary of State’s business database before you commit to a name. If you want to lock in a name but aren’t ready to file yet, you can reserve it by submitting Form 534B with a $39 fee.2Ohio Secretary of State. Filing Forms and Fee Schedule Reservation is optional. If you’re ready, skip it and file.
Line Up a Statutory Agent
Every Ohio LLC must name a statutory agent to receive lawsuits and legal notices. The agent is either an Ohio resident individual or a business entity authorized to operate in Ohio.3Ohio Secretary of State. Frequently Asked Questions About Starting and Maintaining a Business The address must be a physical Ohio location where someone can answer the door during business hours. P.O. boxes and commercial mail receiving agencies are prohibited.4Ohio Secretary of State. Instructions for Statutory Agent Update – Form 521 Instructions
You can appoint yourself if you have a qualifying Ohio address and don’t mind your address appearing in public records. Third-party registered agent services generally charge around $100 to $300 per year if you’d rather keep your address private or guarantee someone is present during business hours. Whoever you name has to sign an acceptance on the Articles of Organization, so get that arranged before filing.
File the Articles of Organization
The Articles of Organization are what actually create your LLC. Ohio uses Form 610, which replaced the older Form 533A in September 2025.2Ohio Secretary of State. Filing Forms and Fee Schedule Under ORC § 1706.16, the filing needs only three things:5Ohio Legislative Service Commission. Chapter 1706 – Ohio Revised Limited Liability Company Act – Section 1706.16
- The LLC’s name, with a valid designator.
- The statutory agent’s name, Ohio street address, and signed acceptance.
- Any additional provisions you want to include, such as a stated business purpose or a defined period of existence.
Most organizers keep the purpose broad (“any lawful activity”) and go with perpetual existence, which is the default if you don’t set an end date. You can also choose an effective date up to 90 days out if you want the LLC to come into legal existence on a later date rather than on the day the Secretary of State processes the filing.6Ohio Secretary of State.

Filing Online
The fastest route is Ohio Business Central, the Secretary of State’s online portal. The base filing fee is $99. If you need it faster, three levels of expedited processing are available on top of the base fee:7Ohio Secretary of State. Form 610 – Articles of Organization for a Domestic Limited Liability Company
- Level 1 adds $100 for processing within 2 business days.
- Level 2 adds $200 for processing within 1 business day.
- Level 3 adds $300 for 4-hour processing if received by 1:00 p.m., or by noon the next business day if received later. Level 3 requires in-person delivery.
All fees are non-refundable. Once the state approves your filing, you get a certificate of organization with a charter number that identifies your LLC in every future dealing with the state. Save the certificate; banks and other agencies will ask for it.
Filing by Mail
If you’d rather file paper, send Form 610 with a check or money order payable to “Ohio Secretary of State” to P.O. Box 1390, Columbus, OH 43216. Paper filings take longer because of mail transit and manual processing. You can watch your filing status on the Secretary of State’s business search database and see when the LLC switches to active.
Get an EIN From the IRS
Once the state has approved your LLC, apply for a federal Employer Identification Number. The nine-digit EIN functions like a Social Security number for the business. You’ll need it for tax filings, and most banks won’t open a business account without one.8Internal Revenue Service. About Form SS-4, Application for Employer Identification Number
The IRS online EIN application is the quickest option and issues the number immediately when approved.9Internal Revenue Service. Get an Employer Identification Number The application asks you to name a “responsible party,” who must be an individual (not another entity) who controls or manages the LLC’s funds and assets.10Internal Revenue Service. Responsible Parties and Nominees For most new LLCs, that’s a founding member. Have their Social Security number ready.
Put an Operating Agreement in Place
Ohio doesn’t make you file an operating agreement with the state, but going without one is a mistake, especially with multiple members. Under ORC § 1706.08, the operating agreement governs the relationship among members and between members and the company. Where it’s silent, Ohio’s default statutory rules fill the gap, and the defaults may not match what you actually want.11Ohio Legislative Service Commission. Ohio Revised Code 1706.08 – Limited Liability Company Operating Agreements
At a minimum, cover how profits and losses are split, what happens when a member wants to leave or a new one joins, who has authority to sign contracts and move money, and how the LLC gets dissolved if it comes to that. Ohio law gives operating agreements broad power to modify the default rules. You can even limit or eliminate certain fiduciary duties among members, though you cannot eliminate the implied covenant of good faith and fair dealing.11Ohio Legislative Service Commission. Ohio Revised Code 1706.08 – Limited Liability Company Operating Agreements The agreement can also spell out penalties for members who don’t hold up their end, including forced sale or forfeiture of a membership interest.
Even single-member LLCs should have one. Without it, the line between you and the business gets blurry, which is the kind of situation that invites a court to disregard your liability protection. The agreement doesn’t need to be long, but it should exist and be signed.
Know How Your LLC Will Be Taxed
An LLC has no federal tax category of its own. The IRS assigns a default based on the number of members. A single-member LLC is a “disregarded entity,” with income and expenses flowing through to your personal return. A multi-member LLC is treated as a partnership, filing Form 1065 and issuing K-1s to each member.12Internal Revenue Service. LLC Filing as a Corporation or Partnership
Either type can elect corporate taxation by filing Form 8832, and some LLCs go further and elect S-corporation status.12Internal Revenue Service. LLC Filing as a Corporation or Partnership Both elections carry real consequences and deadlines; talk to a tax professional before filing either.
Ohio doesn’t impose a traditional state income tax on the LLC itself. Members pay Ohio individual income tax on their share of the earnings. The main state-level business tax is the Commercial Activity Tax, which is based on gross receipts rather than profit. For tax years 2025 and forward, only businesses with more than $6 million in Ohio taxable gross receipts owe the CAT, at a rate of 0.26%.13Ohio Department of Taxation. Commercial Activity Tax A business that crosses the threshold has 30 days to register. Most new LLCs won’t come near that number early on, but if you’re forming an LLC around an already-established Ohio business with significant revenue, register promptly to avoid penalties.
Open a Business Bank Account
Separate accounts for personal and business money are how you preserve the liability shield your LLC gives you. Mixing funds hands creditors an argument that the LLC is just an extension of you personally, which is what leads a court to pierce the veil and hold you liable for business debts.
Banks usually want your certificate of organization (or a certified copy), your EIN confirmation, government-issued ID for each member or manager with signing authority, and your operating agreement.14U.S. Small Business Administration. Open a Business Bank Account Requirements vary, so call ahead.
What You Have to Keep Up With
Ohio is unusually light on annual paperwork. Unlike most states, it does not require LLCs to file an annual or biennial report with the Secretary of State. There’s no recurring state filing fee just to stay in good standing, which saves both time and money compared with states that charge $50 to $300 a year for a routine information update.
No annual report doesn’t mean no obligations. You have to keep your statutory agent information current. If your agent’s address changes or your agent resigns, update the Secretary of State using Form 521. Failing to maintain a valid statutory agent can put your LLC’s standing at risk. You also need to keep any local business licenses your city or county requires and stay current on federal and Ohio tax filings tied to your LLC’s activity.
On federal Beneficial Ownership Information reporting, domestic Ohio LLCs are currently exempt from FinCEN filing following a March 2025 interim final rule that removed the obligation for all U.S.-created companies.15FinCEN.gov.
