ein for vietnam

Vietnamese entrepreneurs can get a US EIN by submitting IRS Form SS-4 by fax. Your Vietnam 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, and delivers your EIN by email. Standard costs $49 (4-7 business days). Express costs $97 (2-3 business days).

Vietnam is one of Asia's fastest-growing economies, with a GDP near $409 billion and a population of 99 million. Vietnamese founders increasingly build for the US market: manufacturers and trading companies shipping goods to American buyers, Amazon and Shopify sellers, software outsourcing firms, and freelancers invoicing US clients in dollars. Every one of them needs a US EIN to operate a US business entity. This guide explains how Vietnamese applicants get an EIN without an SSN, how to complete Form SS-4, and how to set up US banking and payments after approval. The IRS charges $0 for the EIN.

Use Cases

Why Do Vietnamese Entrepreneurs Need a US EIN?

Vietnamese 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 federal tax ID that connects your Vietnamese-owned company to the US financial system.

Vietnam's strong manufacturing base, export sectors, and growing software industry push founders toward the US, where customers, payment processors, and capital concentrate. Here are the most common reasons Vietnamese applicants come to ein.so.

E-commerce and Amazon.com

Vietnamese sellers expanding to Amazon.com need a US tax ID for the seller tax interview. A US LLC and EIN unlock FBA warehouses, US payouts, and direct access to American buyers for products manufactured in Vietnam.

Manufacturers and Trading Companies

Vietnamese factories and trading firms form a US LLC to invoice American importers in dollars, present a US business identity on contracts, and simplify payment from US wholesale buyers.

Freelancers and Outsourcing

Vietnamese freelancers and software outsourcing teams serving US clients form a US LLC to bill in USD, avoid unfavorable PayPal conversion to Dong, and look credible to American customers.

SaaS and Digital Products

App developers, course creators, and digital-product sellers use a US entity and EIN to access US payout rails and platforms that reward a US business presence.

Every use case above shares one requirement: the EIN comes before the bank account, the marketplace registration, and the payment processor. Learn more on EIN for non-residents and the full EIN application process.

Step-by-Step

How Do Vietnamese Citizens Apply for a US EIN?

Vietnamese citizens submit IRS Form SS-4 by fax to 855-215-1627, using a Vietnam passport number in place of an SSN. The IRS online tool requires an SSN, so the fax method is the only path for Vietnamese applicants. The IRS issues most correctly filed EINs within 4-7 business days.

1

Form Your US LLC

Most Vietnamese founders register an LLC in Wyoming, Delaware, or New Mexico through a registered agent. This gives you a US business address and a legal entity to attach the EIN to. You form the LLC entirely online from Vietnam.
2

Gather Your Documents

You need your Vietnam passport (valid and unexpired), your LLC formation details (name, state, formation date), and your Vietnam address. No Vietnam Tax Code or business registration is required for the EIN.
3

Complete Form SS-4

Enter your US LLC name on Line 1, your Vietnam address on Line 4, your full name as responsible party on Line 7a, and your Vietnam passport number on Line 7b. ein.so completes this for you to prevent errors.
4

Submit by Fax and Receive Your EIN

The SS-4 is faxed to the IRS at 855-215-1627. Standard delivery is 4-7 business days; Express is 2-3 business days. The IRS returns your EIN assignment letter (CP 575) by fax, and ein.so emails it to you.

Vietnam-Specific SS-4 Field Guide

SS-4 FieldVietnamese Entry
Line 1 (Legal name)Your US LLC name
Line 4 (Address)Your Vietnam address (phuong, quan, tinh)
Line 7a (Responsible party)Your full name as on your passport
Line 7b (SSN/ITIN/EIN)Your Vietnam passport number
Line 10 (Reason)Started new business
Line 16 (Principal activity)E.g., "e-commerce," "manufacturing," "consulting"

The most common Vietnamese rejection cause is address formatting. The phuong and quan structure does not map cleanly to the SS-4 layout, and the IRS silently rejects malformed international addresses. ein.so reformats Vietnam addresses to an IRS-accepted style. See the full SS-4 form guide and the EIN without SSN guide.

Banking & Payments

How Do Vietnamese Entrepreneurs Use Their EIN for US Banking and Payments?

Vietnamese entrepreneurs use their EIN to open a US business bank account and connect US payment processors, which together give a Vietnam-owned LLC full access to the dollar economy. Mercury and Relay approve most Vietnamese LLC owners remotely within a few business days.

US Business Bank Account

Mercury, Relay, and Wise accept Vietnamese LLC owners with an EIN and a passport. You receive US account and routing numbers for ACH and domestic wires. See EIN for a bank account.

Stripe on a US Entity

A US LLC and EIN let you bill US customers as a US business, settle in USD, and access features tied to a US entity. This avoids conversion losses to Vietnamese Dong on every sale. See EIN for Stripe.

PayPal Business (US)

A US PayPal Business account linked to your EIN holds USD without forced conversion to Dong, which improves margins on US sales. See EIN for PayPal.

Wise and International Transfers

Vietnamese founders use Wise to move funds between their US account and a Vietnam bank account at the mid-market rate, converting to Dong only when needed. See EIN for Payoneer for an alternative.

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 Vietnam when the rate is favorable.

Pricing & Timing

How Much Does an EIN Cost for a Vietnamese Applicant?

The IRS charges $0 for an EIN. ein.so charges $49 for Standard service (4-7 business days) and $97 for Express service (2-3 business days), covering Form SS-4 preparation, the fax to the IRS, and email delivery of your EIN letter.

The choice for Vietnamese applicants is method, not price floor. Calling the IRS at 267-941-1099 means international calls during US business hours, long holds, and live English Q&A. The fax method removes the call entirely.

Tax Considerations

What Should Vietnamese Entrepreneurs Know About US Tax Compliance?

A single-member US LLC owned by a Vietnamese resident is usually a disregarded entity for US federal income tax. The LLC owner files Form 5472 with a pro-forma Form 1120 each year. The penalty for not filing is $25,000.

US Filing: Form 5472 + 1120

A foreign-owned single-member US LLC must file Form 5472 with a pro-forma Form 1120 each year. The penalty for not filing is $25,000. This is an information return, not always a tax bill.

BOI Report to FinCEN

Most US LLCs must report beneficial ownership to FinCEN. Review the BOI filing rules to avoid penalties. Filing the report directly at fincen.gov/boi costs $0.

Vietnam Reporting

Vietnamese residents may have reporting duties for foreign company interests and foreign accounts. Confirm your obligations for a foreign-held US LLC with a Vietnamese tax professional.

Treaty and Withholding

The US and Vietnam have an income tax treaty framework. Treaty effects on dividends, interest, and royalties depend on facts. Confirm withholding and double-taxation relief with a CPA.

ein.so handles the EIN application and does not provide tax advice. Work with a Vietnamese tax professional and a US CPA familiar with non-resident matters. Your EIN is the starting point for US tax compliance, not the end. The ITIN service from ein.so costs $197 Standard or $297 Express if you later need an individual tax ID for treaty claims or personal filings; confirm with a CPA whether you need one.
