EIN in Ohio (OH)
How to get an EIN for your Ohio business. The EIN is a federal number from the IRS, identical in every state. Non-residents apply with a passport, no SSN required. $49 Standard. $97 Express.
Getting an EIN in Ohio follows the same federal IRS process as every other state. The EIN is a federal number, not state-specific. Non-residents file IRS Form SS-4 by fax to 855-215-1627 and enter a passport number on Line 7b. No SSN or ITIN is needed. The IRS online tool requires an SSN, so the fax method is the path for non-residents. The IRS charges $0. ein.so prepares and files your SS-4 for $49 Standard (4-7 business days) or $97 Express (2-3 business days).
Ohio (OH) is one of the largest economies in the US Midwest, anchored by manufacturing, logistics, healthcare, and a growing technology base across Columbus, Cleveland, and Cincinnati. Founders form Ohio entities to reach US customers, hire US contractors, and access US payment rails. Every Ohio business that opens a bank account, hires employees, or files US taxes needs a federal EIN. This guide explains how to get an EIN in Ohio, how the federal EIN differs from Ohio state registration, and how non-residents apply with a passport instead of an SSN.

Ohio
Is an Ohio EIN Different From a Federal EIN?
No. An Ohio EIN is a federal EIN. The IRS issues one 9-digit number that works in all 50 states. Ohio does not assign its own EIN. The same number serves your Ohio business for federal tax filing, banking, and payroll.
The confusion comes from Ohio's separate state-level registrations. Your federal EIN handles IRS matters. Ohio handles its own taxes through the Ohio Department of Taxation. These are two different identifiers for two different governments.
| Identifier | Issued By | Used For |
|---|---|---|
| Federal EIN | IRS | Federal tax, banking, payroll, Form 5472 |
| Ohio state tax account | Ohio Department of Taxation | Sales tax, employer withholding |
| Ohio vendor's license | Ohio (county/state) | Collecting Ohio sales tax |
Your EIN does not replace Ohio state registration. Many Ohio businesses need both. Confirm which Ohio registrations apply to your activity with a CPA. See state tax ID for how the two layers fit together, and EIN cost for a full price breakdown.
Non-Residents
Can a Non-Resident Get an EIN for an Ohio Business?
Yes. A non-resident can get an EIN for an Ohio business without an SSN, an ITIN, or a US visit. The IRS accepts a passport number on Form SS-4 Line 7b. You form an Ohio LLC remotely, then file the SS-4 by fax from abroad.
The IRS online EIN tool is blocked for applicants without an SSN. That is the single reason non-residents use the fax method instead. The fax route is the standard, IRS-approved path for foreign founders.

How to Apply
How Do You Get an EIN in Ohio?
You get an EIN in Ohio through one of four IRS methods: online (instant, SSN required), fax (4-7 days), phone (same day, US callers), or mail (4 or more weeks). Non-residents use fax because the online tool requires an SSN.
The process is federal and identical in every state, so nothing about Ohio changes the SS-4 itself. See how to get an EIN for the full walkthrough and EIN processing time for current speed expectations.
| Method | Speed | Cost | SSN Needed |
|---|---|---|---|
| Online (irs.gov) | Instant | $0 | Yes |
| Fax (855-215-1627) | 4-7 days | $0 / $49 | No |
| Phone (800-829-4933) | Same day | $0 | No (US hours) |
| 4+ weeks | $0 | No |

SS-4 Fields
How Do You Fill Out Form SS-4 for an Ohio LLC?
You fill out Form SS-4 with your Ohio LLC name on Line 1, your address on Line 4, your name on Line 7a, and your passport number on Line 7b if you have no SSN. Each field has an exact entry the IRS expects.
The most common rejection cause is address formatting for international applicants. The IRS silently rejects malformed foreign addresses. ein.so reformats your address to an IRS-accepted style so the application is not lost.
| SS-4 Field | Entry for an Ohio LLC |
|---|---|
| Line 1 (Legal name) | Your Ohio LLC name |
| Line 4 (Mailing address) | Your address (US or foreign) |
| Line 7a (Responsible party) | Your full name as on your passport |
| Line 7b (SSN/ITIN/EIN) | Passport number if no SSN |
| Line 8a (LLC) | Yes, with member count |
| Line 10 (Reason) | Started new business |
| Line 16 (Principal activity) | E.g., software, e-commerce, consulting |
After the EIN arrives, you complete your Ohio Department of Taxation registrations and open banking. See the full SS-4 form guide and how to get an EIN for line-by-line detail.

Tax Considerations
What Are the Tax Filings for a Foreign-Owned Ohio LLC?
A foreign-owned single-member Ohio LLC files Form 5472 with a pro-forma Form 1120 each year. The penalty for missing this information return is $25,000. This federal requirement applies to an Ohio LLC the same as any other state.
A single-member US LLC owned by a non-resident is usually a disregarded entity for US federal income tax. The filing is informational, not automatically a tax bill. State-level Ohio taxes are a separate question handled through the Ohio Department of Taxation.
