How to Form an LLC in Ohio (2026): Real Costs, Real Steps
Forming an LLC in Ohio costs $99 to file Articles of Organization with the Secretary of State. You'll need a registered agent with an Ohio street address—Northwest Registered Agent handles this for $125 annually. Ohio doesn't require publication or have state-level annual reports, but you must file a business income tax return with the state if you have nexus. After filing Articles, obtain your EIN from the IRS (free), draft an Operating Agreement (internal document), open a business bank account (Mercury makes this straightforward), and register for Ohio Commercial Activity Tax if your gross receipts exceed $150,000 annually. Total first-year cost: approximately $224 using Northwest as your registered agent.
Before you file, two things drive cost the most in Ohio: registered agent requirements and whether you open Mercury vs Bluevine business banking separately. The full breakdown below covers both.

The 6 steps
- Step 1: File Articles of Organization
Submit the formation document to the Ohio Secretary of State. See the cost table above for the current filing fee.
- Step 2: Appoint a Registered Agent
Every Ohio LLC needs a registered agent with a Ohio street address. You can serve yourself, but most founders use a commercial RA — Northwest is our default pick.
- Step 3: Get an EIN (Federal Employer Identification Number)
Apply with the IRS using your stamped Articles of Organization. Free, takes 5 minutes online.
- Step 4: Adopt an Operating Agreement
Required by best practice — banks routinely request it before opening business accounts.
- Step 5: Open a Business Bank Account
Mercury for software/online businesses; a local credit union for cash-heavy retail. Keep personal and business finances separate from day one.
- Step 6: File State Tax Registrations
Register for Ohio state taxes (sales tax permit, payroll registration if you have employees, etc.) before you transact.

Frequently asked questions
Does Ohio require an annual LLC report or franchise tax?
No. Ohio eliminated annual report requirements for LLCs. You only need to maintain an active registered agent and comply with state tax obligations. This makes Ohio one of the more affordable states for ongoing LLC maintenance.
What is Ohio's Commercial Activity Tax and when does it apply?
The CAT is a gross receipts tax on businesses with taxable gross receipts over $150,000 annually. The rate is 0.26% on receipts above $1 million (tiered lower for smaller amounts). Register at tax.ohio.gov if you exceed the threshold. This is separate from federal income tax.
How long does Ohio take to process LLC formation documents?
Standard processing is 5-7 business days. Expedited service (2-3 business days) costs an additional $100, and same-day service costs $200 extra. File online at ohiosos.gov for fastest processing. Mail filings take longer.
Can I use a PO Box for my Ohio registered agent address?
No. Ohio requires a physical street address within the state for your registered agent. Northwest Registered Agent provides a Columbus address and scans/forwards legal mail for $125/year, meeting this requirement.
Do Ohio LLCs need to publish formation notices in newspapers?
No. Ohio does not require publication of LLC formation in newspapers, unlike states such as New York or Arizona. Once your Articles are filed and accepted, your LLC is legally formed without additional publication costs.
Annual filing deadline
Ohio does not require annual reports or franchise taxes for LLCs, but you must maintain good standing with your registered agent and file applicable state tax returns such as the Commercial Activity Tax if your annual gross receipts exceed $150,000.
