An Employer Identification Number is the federal tax ID your Ohio LLC needs to open a business bank account, hire employees, or accept payments. We obtain it from the IRS on your behalf after Ohio approves your LLC.
An Employer Identification Number — EIN — is a nine-digit federal tax ID assigned by the Internal Revenue Service. It's to your LLC what a Social Security number is to an individual: a unique identifier that the federal government, banks, payment processors, and payroll systems use to track the entity.
Every Ohio LLC that plans to open a business bank account, hire employees, or file federal taxes as a partnership or corporation will need an EIN. The only LLCs that can technically operate without one are disregarded single-member LLCs that never hire anyone and use the owner's Social Security number for everything — which is rarely practical once you're actually in business.
The EIN application requires a formed entity. We don't submit the SS-4 until the Ohio Secretary of State returns your stamped Articles of Organization — usually 3–5 business days after filing.
A formation specialist completes the SS-4 with your LLC's name, Ohio formation date, principal business activity, and member information — the classification you've elected (disregarded, partnership, S-corp, C-corp).
For most founders (U.S. person as responsible party, valid SSN or ITIN) the online IRS system issues the EIN the same day. For non-U.S. responsible parties we submit by fax, which takes roughly four business days.
You receive the official IRS confirmation letter (CP 575 or equivalent) — the document every U.S. bank requires to open the business account in your Ohio LLC's name.
Ohio does not require an annual report or annual fee for LLCs. Once the Articles of Organization are approved, there is no recurring state-level filing with the Secretary of State. You still have federal tax obligations and state Commercial Activity Tax above the gross-receipts threshold, but the SOS side is one-and-done.
An EIN is a federal identifier. It is not a business license, an Ohio state tax ID, a seller's permit, or a DBA registration. If your business collects Ohio sales tax or has employees in Ohio, you'll also need to register with the state's tax authority — that is separate from the EIN and is not part of the $299 formation package.
Reservation takes three minutes. A formation specialist in Columbus handles the rest.
