EIN for Japanese Entrepreneurs
Apply for your US EIN from Japan without an SSN or ITIN. ein.so handles the IRS fax filing for Japanese freelancers, Amazon sellers, and SaaS founders. $49 Standard. $97 Express.
Last updated: June 2, 2026
Japanese entrepreneurs can get a US EIN by submitting IRS Form SS-4 by fax. Your Japan passport number replaces the SSN requirement on Line 7b. The IRS online tool is blocked for applicants without an SSN, so the fax method is your path. ein.so prepares your SS-4, faxes it to the IRS at 855-215-1627, and delivers your EIN by email. Standard processing costs $49 (4-7 business days). Express costs $97 (2-3 business days).
Japan is the third-largest economy in the world, with a GDP near $4.2 trillion and a population of 125 million. Japanese founders increasingly build for the US market: SaaS and app developers, Amazon and Shopify sellers shipping Japanese design and craft products, content creators, and consultants invoicing American clients. To operate a US business entity, every one of them needs a US EIN. This guide explains how Japanese applicants get an EIN without an SSN, how the US-Japan tax treaty interacts with a US LLC, and how to set up US banking and payments after approval.
| Factor | Japan | United States |
|---|---|---|
| Common entity | Sole proprietor / KK / GK | LLC / Corporation |
| Business ID | My Number (12) / Corporate Number (13) | EIN (XX-XXXXXXX) |
| Tax authority | National Tax Agency (NTA) | IRS |
| Consumption / sales tax | Consumption tax (10%) | State sales tax (varies) |
| Currency | Japanese Yen (JPY, ~0.0067 USD) | USD |
| US tax treaty | Yes (US-Japan income tax treaty) | — |
Use Cases
Why Do Japanese Entrepreneurs Need a US EIN?
Japanese entrepreneurs need a US EIN because a US LLC cannot open a bank account, accept US payments, or file US taxes without one. The EIN is the 9-digit federal tax ID that links your Japan-owned company to the US financial system.
Japan's strong export sectors in technology, design, food, and gaming push founders toward the US, where customers, payment processors, and platforms concentrate. Here are the most common reasons Japanese applicants come to ein.so.
SaaS and App Developers
E-commerce and Amazon.com
Freelancers and Consultants
Content Creators and Digital Products
Across all four use cases, the EIN comes first. You cannot open a US bank account, pass a marketplace tax interview, or file a US return without it.
Step-by-Step
How Do Japanese Citizens Apply for a US EIN?
Japanese citizens submit IRS Form SS-4 by fax to 855-215-1627, using a Japan passport number in place of an SSN. The IRS online tool requires an SSN, so the fax method is the only viable path for Japanese applicants. The IRS issues most correctly filed EINs within 4-7 business days.

Japan-Specific SS-4 Field Guide
| SS-4 Field | Japanese Entry |
|---|---|
| Line 1 (Legal name) | Your US LLC name |
| Line 4 (Address) | Your Japan address (banchi, city, prefecture, postal code) |
| Line 7a (Responsible party) | Your full name as on your passport |
| Line 7b (SSN/ITIN/EIN) | Your Japan passport number |
| Line 10 (Reason) | Started new business |
| Line 16 (Principal activity) | E.g., "software," "e-commerce," "consulting" |
A common Japanese rejection cause is address formatting. The Japan address order runs from large to small (prefecture first), which does not map to the SS-4 layout, and the IRS rejects malformed international addresses. ein.so reformats your Japan address to an IRS-accepted style. See the full SS-4 form guide and the complete EIN application process.

Banking & Payments
How Do Japanese Entrepreneurs Use Their EIN for US Banking and Payments?
Japanese entrepreneurs use their EIN to open a US business bank account and connect US payment processors, which together give a Japan-owned LLC full access to the dollar economy. Mercury and Relay approve most Japanese LLC owners remotely within a few business days.
US Business Bank Account
Stripe on a US Entity
PayPal Business (US)
Wise Multi-Currency
Together, a US LLC, an EIN, and a US bank account let you invoice American clients in dollars, accept card payments through Stripe, and repatriate profits to your Japan bank when the exchange rate works in your favor.
Tax Considerations
What Should Japanese Entrepreneurs Know About US and Japan Taxes?
A single-member US LLC owned by a Japan resident is usually a disregarded entity for US federal income tax, meaning the LLC itself pays no US federal income tax on non-US-sourced income. The US-Japan income tax treaty helps prevent double taxation and can reduce US withholding on certain passive income.

ein.so handles the EIN application and does not provide tax advice. Work with a Japan tax accountant and a US CPA familiar with non-resident matters. Confirm all tax specifics with a CPA. Your EIN is the starting point for US tax compliance. See our EIN without SSN guide and EIN for non-residents.
Comparison
Should Japanese Founders Choose Standard or Express EIN?
Japanese founders choose Standard EIN ($49, 4-7 business days) when there is no deadline, and Express EIN ($97, 2-3 business days) when a bank, marketplace, or investor is waiting. Both methods use the same IRS fax filing and require no SSN.
When Express ($97) is worth it for Japanese applicants
- A Mercury or Relay bank application is on hold waiting for your EIN.
- An Amazon.com or Shopify launch date is fixed and approaching.
- A US client or platform requires your tax ID before a contract starts.
- You filed during a US tax-season backlog and need certainty on timing.
If your launch is flexible, Standard at $49 delivers the same EIN for less. If you also need an ITIN for personal US tax filing, ein.so offers an ITIN service at $197 Standard or $297 Express. The EIN and ITIN are separate IDs: the EIN is for your business, the ITIN is for you as an individual.

Does the US-Japan tax treaty reduce my taxes?

A single-member US LLC owned by a Japan resident is usually a disregarded entity for US federal income tax. Confirm with a CPA.
What is the EIN equivalent in Japan?
The closest Japan equivalent is the My Number (12 digits) for individuals and the Corporate Number (13 digits) issued by the National Tax Agency. Neither has any standing in the United States. You need a separate US EIN to open US accounts, register on US platforms, and file US returns for a US LLC.
Can Japanese freelancers use a US LLC and EIN?
Yes. Many Japanese freelancers form a US LLC to invoice US clients in dollars, access US payment rails, and present a US business identity on contracts. The US LLC and EIN sit alongside your Japan sole proprietorship. You continue to declare income in Japan under National Tax Agency rules.
Can I sell on Amazon.com from Japan with an EIN?
Yes. Amazon requires a US tax identification number to complete the seller tax interview on Amazon.com. Japanese sellers expanding from Amazon.co.jp use their US EIN to register through their US LLC, access FBA warehouses in the US, and reach American customers in dollars.
What does an EIN cost for a Japanese applicant?
