Ohio Articles of Organization do not require member names on the public filing. The statutory agent address is the primary public record. Out-of-state owners and privacy-conscious founders use a commercial statutory agent service to keep their home address off the public ohiosos.gov record.

1. Check name availability with the Ohio Secretary of State Search the Ohio Secretary of State business name database at businesssearch.ohiosos.gov to confirm your desired LLC name is available. The name must include a valid designator (LLC, L.L.C., Limited Liability Company, etc.) and must not be deceptively similar to an existing Ohio entity. Ohio allows name reservations for 180 days — useful while preparing Articles.
2. Appoint an Ohio statutory agent Designate a statutory agent (Ohio's term for registered agent) with a physical Ohio street address — no PO boxes. Ohio residents may self-serve. Out-of-state owners and remote-first Columbus entrepreneurs typically use a commercial statutory agent service ($50–$150/yr) to maintain a compliant Ohio address and preserve personal address privacy.
3. File the Articles of Organization with the Ohio Secretary of State File online at ohiosos.gov. The Articles require the LLC name, effective date, statutory agent name and Ohio street address, and organizer signature. Pay the $99 filing fee. Standard online processing is typically 3–5 business days; expedited (next business day or same day) processing is available for an additional fee.
4. Draft an Operating Agreement Ohio's LLC Act (ORC § 1706) provides default rules, but an Operating Agreement is critical for Columbus R&D and tech LLCs, Intel supply-chain manufacturers, and any multi-member entity where voting rights, capital contributions, and buyout triggers need clear definition. Ohio does not require the Operating Agreement to be filed with the state.
5. Obtain an EIN from the IRS After the Articles are approved, apply for an EIN at irs.gov/ein. The online application takes under 15 minutes and issues the EIN immediately. Print the CP 575 EIN Confirmation Letter for bank account opening and tax registrations.
6. Register with RITA for Columbus municipal income tax If the LLC has employees or earns business income within Columbus city limits, register with the Regional Income Tax Agency (RITA) at ritaohio.com. Columbus's 2.5% municipal income tax applies to net profits earned within city limits. RITA administers taxes for Columbus and surrounding municipalities — if you have employees across multiple Ohio municipalities, RITA can administer multi-municipality compliance through a single registration.
7. Register for Ohio Commercial Activity Tax (CAT) if gross receipts exceed $150,000 If the LLC's Ohio taxable gross receipts exceed or are expected to exceed $150,000 in a calendar year, register for the Commercial Activity Tax at tax.ohio.gov. The first $150K is fully exempt. Above $150K, the CAT rate is 0.26% of total gross receipts. Annual CAT return is due for businesses with $1M or less in Ohio gross receipts; quarterly for businesses above $1M.
8. Register for Ohio sales tax if selling taxable goods or services If the LLC sells tangible personal property or taxable services in Ohio, register for an Ohio Vendor's License at tax.ohio.gov before the first taxable sale. Columbus's combined sales tax rate is 7.5% (Ohio state 5.75% + Franklin County 1.75%). No additional city sales tax surcharge applies in Columbus.
9. Open a business bank account Bring your EIN Confirmation Letter, Articles of Organization approval, and Operating Agreement to the bank. Columbus's banking market includes Huntington National Bank (headquartered in Columbus), Chase, KeyBank, Fifth Third, and all major national banks. A separate business account is the foundation of the LLC's liability shield.

Formation context

Who should form in Ohio?

Recommended for

Columbus-area entrepreneurs, contractors, and small business owners seeking one of the lowest initial + recurring LLC costs in the Midwest; Tech, healthcare, R&D, and manufacturing LLCs leveraging Ohio State University's research ecosystem and Columbus's Intel-driven semiconductor supply-chain expansion; Remote-first business owners who want a compliant Ohio entity with no annual report obligation and low franchise-tax exposure

Tax treatment (default)

Pass-through by default: single-member LLCs are disregarded entities (Schedule C); multi-member LLCs are partnerships (Form 1065). Ohio imposes a 3.5% flat individual income tax on pass-through income for Ohio residents. The Commercial Activity Tax (CAT) applies at the entity level on Ohio gross receipts above $150K (0.26%). Columbus's 2.5% municipal income tax applies to net profits earned within city limits. Ohio levies no separate franchise tax on LLCs.

For businesses physically operating in Ohio, forming directly in Ohio avoids the dual-state cost trap. A Wyoming or Delaware LLC that operates in Columbus must register as a foreign LLC in Ohio, pay that state's annual fees, AND meet all Ohio CAT and RITA requirements. Ohio's $99 formation and no annual report eliminate the recurring cost advantage of forming elsewhere.

No publication requirement in Ohio — unlike New York or Nebraska, you do not need to publish notice in a newspaper after filing.

FAQ

Common Ohio (Columbus) LLC formation questions

Still deciding between an LLC, sole proprietorship, S-Corp, or C-Corp? Our entity-type comparison breaks down formation cost, tax treatment, liability shield, and compliance complexity for all four structures side by side.

Once your LLC clears ~$80K in annual net profit, an S-Corp election (IRS Form 2553) typically saves $5,000–$15,000/year in self-employment taxes by splitting owner income into a W-2 salary + tax-free distributions. The election is free — Form 2553 has no IRS filing fee. The key decision factors: your net income level, a defensible reasonable-compensation salary, and the 75-day Form 2553 filing window after LLC formation.

Already operating as a sole proprietor, or wondering whether a cheap county DBA filing ($10–$100) is enough instead of forming an LLC? A DBA lets you operate under a trade name — but provides zero liability protection. Our DBA vs LLC comparison breaks down exactly when a DBA is sufficient and when you need a state LLC filing.

Missing your annual report deadline triggers late fees and — if left long enough — administrative dissolution, which voids your LLC's liability shield until reinstated. Know your Ohio deadline, fee, and the consequences of missing it.

Also see the LLC annual report requirements hub for state-by-state deadlines, fees, late penalties, and reinstatement rules.

If your LLC opens an office, hires employees, or regularly does business in another state, you must foreign-qualify there — or face fines, back taxes, and loss of standing to sue. Our foreign qualification guide covers when you need it, how to file a Certificate of Authority, and what it costs.

Your Articles of Organization are filed — now make your LLC operational. Four actions every new LLC owner needs to take:

Formation gets your LLC into existence; contracts, trademark protection, operating agreement review, and vendor-document review keep it usable. Compare subscription and per-document legal platforms before you rely on a template or pay a local attorney retainer.

Commingling personal and business funds is the #1 way LLC owners lose their liability shield. A separate business account — in your LLC's legal name, with your EIN — is the foundational act of corporate formality. Mercury, Novo, Bluevine, Relay, and Found open same-day with no monthly fees. Compare online banks vs. Chase and Bank of America.

How you pay yourself depends on your LLC's tax classification — not what you call the transfer. A disregarded single-member LLC pays via owner draw with SE tax on all net profit. An S-Corp-elected LLC splits income between a W-2 salary (FICA applies) and tax-free distributions. Getting this wrong triggers IRS audit risk and SE-tax errors.

Single-member LLCs file Schedule C with their personal Form 1040 (due April 15). Multi-member LLCs file Form 1065 by March 15. S-Corp-elected LLCs file Form 1120-S by March 15. Know your form, your deadline, and the common deductions — home office, vehicle, retirement contributions, and startup costs — before your first April filing.
