Why Wyoming
Why Do Non-Residents Form a Wyoming LLC?
Non-residents form a Wyoming LLC because Wyoming has no state income tax and low annual costs. A Wyoming LLC needs a federal EIN to open a US bank account, accept payments, and file US returns. Forming in Wyoming does not change the federal SS-4 process.
Wyoming attracts international founders for its straightforward formation and privacy-friendly rules. The EIN is required before the entity can function in the US economy. Here are the most common reasons non-residents register a Wyoming LLC and apply for an EIN.
No State Income Tax
US Banking Access
Payment Processing
E-commerce and SaaS
Step-by-Step
How Do Non-Residents Apply for an EIN for a Wyoming LLC?
Non-residents submit IRS Form SS-4 by fax to 855-215-1627, using a passport number in place of an SSN on Line 7b. The IRS online tool requires an SSN, so the fax method is the only path for non-residents. The IRS issues an error-free EIN in 4-7 business days.

Methods Compared
How Can You Get an EIN in Wyoming?
You can get an EIN in Wyoming four ways: online, fax, phone, or mail. The online tool is instant but requires an SSN, which non-US residents do not have. Non-residents use the fax method to 855-215-1627, which returns the EIN in 4-7 business days.
| Method | Speed | Cost | SSN required |
|---|---|---|---|
| Online | Instant | $0 | Yes |
| Fax | 4-7 business days | $0 / $49 | No |
| Phone | Same day | $0 | Often |
| 4-6 weeks | $0 | No |
The process is identical in every state because the EIN is federal. A Wyoming LLC, a Delaware LLC, and a Texas LLC all file the same Form SS-4 with the same IRS.
The IRS online EIN tool blocks non-residents

- Non-US residents do not have an SSN, so the online tool returns an error.
- The fax method to 855-215-1627 accepts a passport number on Line 7b.
- ein.so files the fax for you and delivers the EIN by email.
