Start an Ohio LLC — Step-by-Step

Your LLC's name has to be distinguishable from every other business name already on file with the Ohio Secretary of State. "Distinguishable" is a legal test, not just a gut check — two names that differ only by punctuation, spacing, or filler words like "the" may still be treated as the same. The Secretary of State screens against all entity types on record, not just other LLCs.

Start at the Ohio business name search. Run your proposed name and a few close variations. If something already on file reads too similarly, the state can reject your Articles, which costs you a redo and delays everything downstream.

Ohio naming rules

• The name must include a recognized designator — "LLC," "L.L.C.," "Limited Liability Company," "Limited," "Ltd.," or an acceptable abbreviation.
• It must be distinguishable from all active names in the Secretary of State's records.
• Certain words (for example those implying banking, insurance, or a government agency) require additional approval or are restricted.

Holding a name

If you're not ready to file but want to lock the name, Ohio lets you reserve an available name for a set period through the Secretary of State. Reserving a name doesn't create the LLC — it just holds the name while you square away everything else.

Operating under a different name

If you'll do business under a name other than your LLC's legal name, register that separately as a trade name or fictitious name using Form 534A with the Secretary of State. It's a distinct filing from the Articles of Organization and runs on its own five-year renewal cycle.

Before you file the Articles, you need a statutory agent chosen and ready to be named — Ohio requires the agent's name, Ohio street address, and written acceptance as part of the formation filing.

Ohio uses "statutory agent" where most states say "registered agent." The role is identical: this is the person or business that receives lawsuits, subpoenas, and official state mail for your LLC, and they must stay in place for the life of the company.

Who can serve

• You — if you have a physical Ohio street address (not a P.O. box) and are reliably around during business hours. Your address will show up in the public record.
• Another Ohio resident — a co-owner, an employee, an Ohio attorney, or another trusted person with an Ohio street address.
• A commercial statutory agent service — a company authorized to serve as statutory agent in Ohio. It keeps its professional address on the public record instead of yours and makes sure documents are always received and forwarded.

Why it matters which you pick

Whatever address you list becomes searchable in the state's business database. If you use your home, anyone who looks up the LLC can find it. Many owners choose a commercial service specifically to keep a home address out of a public database, and to guarantee availability if they travel or keep irregular hours.

The Articles of Organization is the filing that brings your LLC into existence in Ohio's records. Most people file it online through Ohio Business Central as Form 533A; it can also be mailed. The state fee covers the Articles and the statutory agent appointment — check the Secretary of State fee schedule for current amounts.

Standard online processing is typically a few business days, and Ohio offers expedited tiers if you need it faster.

What the Articles contain

• LLC name — your full legal name with a valid designator.
• Effective date — immediate, or a future date up to 90 days out.
• Statutory agent — name, Ohio street address, and the agent's signed acceptance.
• Purpose — a general purpose statement is acceptable; Ohio doesn't demand a detailed one.

What you don't include

You don't list members, ownership percentages, business activities, or any financials. The Articles are a short formation document, not a disclosure. Your operating agreement carries the internal detail, and it stays private.

The operating agreement is your LLC's internal rulebook. Ohio doesn't require you to file it, and it never goes into a public database — but you want one in place before you start doing business, add members, or open accounts.

What a solid agreement covers

• Ownership — who the members are and each member's percentage interest.
• Capital contributions — what each member put in and any future contribution obligations.
• Profit and loss allocation — how profits and losses are divided; it doesn't have to track ownership exactly, though it usually does.
• Distributions — when and how cash goes out, and in what order.
• Management — whether the LLC is member-managed or manager-managed, who has authority, and which decisions need a full member vote.
• Voting — whether votes are weighted by ownership or counted per member.
• Transfers — what happens when a member wants to sell or leave, including rights of first refusal or approval rules.
• Dissolution — the circumstances for winding up and how assets are distributed.

For a single-member LLC the agreement reinforces that the company is genuinely separate from you, which supports the liability shield. For a multi-member LLC it's essential — without it, Chapter 1706's statutory defaults govern everything, and they often don't match the owners' intentions.

An Employer Identification Number is a nine-digit federal tax ID the IRS issues at no charge. Think of it as the business version of a Social Security number — you use it on tax filings, to open bank accounts, and when you hire.

When you need one

• Your LLC has more than one member (multi-member LLCs file a partnership return and must have an EIN).
• You plan to hire employees.
• You want a business bank account (most banks require the EIN).
• You've elected S-Corp or C-Corp tax treatment.

A single-member LLC with no employees can technically use the owner's SSN for federal taxes, but most advisors get an EIN anyway. It keeps your Social Security number off business paperwork and streamlines opening a bank account.

How to apply

File your application online using the IRS EIN Assistant over at IRS.gov. Plan on about ten minutes for the form, and since the number is generated on the spot, you can print the confirmation and start using it that day. The online path needs a US SSN or ITIN; applicants without one file Form SS-4 by fax or mail.

Keeping business and personal money separate isn't optional — it's what preserves the liability protection you formed the LLC to get. Pay personal bills from the business account, or funnel business income through your personal checking, and a court can treat the LLC as a formality and reach your personal assets.

What banks usually want

• Filed Articles of Organization from the Secretary of State
• Your IRS EIN confirmation
• The operating agreement (many banks ask for it; have it ready either way)
• Government-issued ID for everyone who'll be an authorized signer

Community banks and credit unions are often more flexible with brand-new LLCs than the big national chains. Several online business banks can open an account without a branch visit. Before you settle on one, weigh the monthly charges, the caps on transactions, and any required minimum balance.

Ohio's continuing obligations are among the simplest anywhere, so most of the work is front-loaded into formation.

No annual report

Ohio does not require LLCs to file an annual or biennial report with the Secretary of State. There's no yearly form, no recurring state report fee tied to one, and no administrative dissolution for missing it — there's simply nothing to file. That's the biggest ongoing difference between Ohio and most other states.

Keep the statutory agent current

If your statutory agent's address changes, the agent resigns, or you switch agents, file the update with the Secretary of State (Form 521) promptly. A stale statutory agent address leaves the LLC technically non-compliant and risks you missing something served to an address nobody watches.

Taxes

Federal treatment depends on how the LLC is taxed: single-member LLCs report on Schedule C, multi-member LLCs file Form 1065, and S-Corp elections file Form 1120-S. Ohio has a personal income tax on the pass-through profits, and the Commercial Activity Tax may apply to gross receipts above a threshold through the Department of Taxation. If you sell taxable goods or services, register for sales tax with the Ohio Department of Taxation.

Licenses

Ohio has no general statewide business license, but many professions require state licensure, and cities and counties often have their own registration or permit rules. These run separately from your Secretary of State filing.
