EIN in Missouri (MO)
How to get an EIN for your Missouri business. The EIN is a federal number from the IRS. Non-residents apply by fax with a passport. $49 Standard. $97 Express.
Getting an EIN in Missouri follows the same federal IRS process as every other state. The EIN is a federal number issued by the IRS, not by Missouri. Non-residents file Form SS-4 by fax to 855-215-1627 and enter a passport number on Line 7b. The IRS online tool requires an SSN, so fax is the path. ein.so prepares and files your SS-4 for $49 Standard (4-7 business days) or $97 Express (2-3 business days).
Missouri sits at the center of the United States and hosts strong logistics, agriculture, and manufacturing sectors around Kansas City and St. Louis. Non-resident founders register a Missouri LLC to gain a US business identity, access US payment rails, and invoice American clients in dollars. Every Missouri business that files US taxes, opens a US bank account, or hires staff needs a federal EIN. This guide explains how non-residents get an EIN for a Missouri business without an SSN, how the federal EIN differs from Missouri state registration, and what to do after approval.

Federal vs State
Is a Missouri EIN Different From a Federal EIN?
No. A Missouri EIN is the same federal EIN issued by the IRS to businesses in every state. The IRS assigns one 9-digit number (XX-XXXXXXX) that works nationwide. Missouri does not issue a separate state version of the EIN.
Your federal EIN and your Missouri state tax registration are two different things. The EIN comes from the IRS for federal tax filing, banking, and payment processing. The Missouri state tax ID comes from the Department of Revenue for state-level obligations like sales tax collection or employer withholding.
| Identifier | Issued By | Used For |
|---|---|---|
| Federal EIN | IRS | Federal tax filing, bank account, Stripe, payroll |
| Missouri state tax ID | Missouri Department of Revenue | State sales tax, employer withholding |
You may need both, depending on your business activity in Missouri. The EIN does not replace state registration. A non-resident with no US employees and no in-state sales may need only the federal EIN. Confirm your state registration duties with a CPA. See state tax ID for the distinction in detail.
How to Apply
How Do You Get an EIN in Missouri?
You get an EIN in Missouri by filing IRS Form SS-4. US applicants with an SSN use the IRS online tool for same-day issuance. Non-residents without an SSN file by fax to 855-215-1627 using a passport number on Line 7b. Most correctly filed faxes return an EIN in 4-7 business days.
| Method | Speed | Cost | SSN Needed |
|---|---|---|---|
| IRS online | Same day | $0 | Yes |
| Fax | 4-7 days | $0 / $49 | No |
| Phone | Same day call | $0 | Varies |
| 4-6 weeks | $0 | No |
The process is identical in every state because the EIN is federal. Missouri location does not change a single SS-4 field. See how to get an EIN for the complete walkthrough and EIN processing time for current timelines.

Non-Residents
Can Non-Residents Get an EIN for a Missouri Business?
Yes. Non-residents get an EIN for a Missouri business without an SSN, an ITIN, or a US visa. The IRS does not require you to live in or visit the United States. Your foreign passport number replaces the SSN on Form SS-4 Line 7b.
The IRS online EIN tool is blocked for applicants without an SSN. That blocker pushes every non-resident to the fax method. The fax route accepts a passport number, so it is the correct and reliable path for international founders. ein.so files this fax for you and handles the address formatting that often triggers silent IRS rejections.

Cost

| Item | Cost | Paid To |
|---|---|---|
| EIN (IRS direct) | $0 | IRS |
| ein.so Standard EIN filing | $49 | ein.so (4-7 business days) |

| Missouri LLC formation | State fee (confirm at sos.mo.gov) | Missouri Secretary of State |
| ein.so ITIN (if needed) | $197 / $297 | ein.so |

Banking & Payments
How Do You Use a Missouri EIN for Banking and Payments?
You use a Missouri EIN to open a US business bank account and connect US payment processors. Together these give a non-resident-owned Missouri LLC full access to the dollar economy. Mercury and Relay approve many non-resident owners remotely within a few business days.
US Business Bank Account
Stripe on a US Entity
PayPal Business
Payoneer and Transfers
A bank will not open a US business account without an EIN. The EIN is the first step after forming the LLC and before any banking or payment setup.
Tax Compliance
What Should Missouri LLC Owners Know About Taxes and Filing?
A single-member US LLC is usually a disregarded entity for US federal income tax, so income passes through to the owner. A foreign-owned single-member Missouri LLC must still file Form 5472 with a pro-forma Form 1120 each year. The penalty for not filing is $25,000.
Federal Filing: Form 5472 + 1120

State Registration
ein.so handles the EIN application and does not provide tax advice. Work with a US CPA familiar with non-resident matters before relying on any tax treatment. Your EIN is the starting point for both federal and Missouri compliance. See EIN for non-residents for the full compliance picture.
After Approval
What Comes After Getting Your EIN in Missouri?
After getting your EIN, you open a US bank account, file your BOI report, connect payment processors, and set up annual Form 5472 filing. The EIN unlocks each of these steps, none of which a bank or processor will allow without it.
