Thai entrepreneurs can get a US EIN by submitting IRS Form SS-4 by fax. Your Thailand 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 costs $49 (4-7 business days). Express costs $97 (2-3 business days).

Thailand has a population of 72 million and a GDP near $495 billion. Thai founders increasingly build for the US market: e-commerce sellers shipping Thai products, freelancers and consultants invoicing American clients, SaaS founders billing in dollars, and digital nomads running location-independent businesses. Each of them needs a US EIN to operate a US business entity. This guide explains how Thai applicants get an EIN without an SSN, how to complete Form SS-4 from Thailand, and how to set up US banking and payments after approval.

Use Cases

Why Do Thai Entrepreneurs Need a US EIN?

Thai 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 Thai-owned company to the US financial system.

Thailand's export strength in fashion, food, handicrafts, and beauty, plus a fast-growing digital nomad and freelance economy, pushes founders toward the US market where customers and payment processors concentrate. Here are the most common reasons Thai applicants come to ein.so.

E-commerce and Amazon.com

Thai sellers expanding to Amazon.com need a US tax ID for the seller tax interview. Thai beauty, fashion, and food brands use a US LLC and EIN to reach American buyers and use FBA warehouses for fast domestic shipping.

Freelancers and Consultants

Thai freelancers serving US clients form a US LLC to invoice in USD, avoid unfavorable currency conversion, and present a credible US business identity on contracts and platforms.

SaaS and Tech Startups

Thai SaaS founders form US LLCs to bill US customers in dollars, integrate Stripe on a US entity, and prepare for US investors. The EIN is required before any of this works.

Content Creators and Digital Products

YouTubers, 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.

Step-by-Step

How Do Thai Citizens Apply for a US EIN?

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

Form Your US LLC

Most Thai 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 Thailand.

Gather Your Documents

You need your Thailand passport (valid and unexpired), your LLC formation details (name, state, formation date), and your Thailand address. No Thai Tax ID or company registration is required for the EIN.

Complete Form SS-4

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

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.

Thailand-Specific SS-4 Field Guide

SS-4 Field	Thai Entry
Line 1 (Legal name)	Your US LLC name
Line 4 (Address)	Your Thailand address (house number, road, district, postal code)
Line 7a (Responsible party)	Your full name as on your passport
Line 7b (SSN/ITIN/EIN)	Your Thailand passport number
Line 10 (Reason)	Started new business
Line 16 (Principal activity)	E.g., "software," "e-commerce," "consulting"

The most common Thai rejection cause is address formatting. The Thai house number, road, sub-district, and 5-digit postal code do not map cleanly to the SS-4 layout, and the IRS silently rejects malformed international addresses. ein.so reformats Thai addresses to an IRS-accepted style. See the full SS-4 form guide and the complete EIN application process.

Cost & Time

How Much Does an EIN Cost for a Thai Applicant?

The IRS charges $0 for an EIN, so a Thai applicant pays only for filing service. ein.so charges $49 for Standard (4-7 business days) or $97 for Express (2-3 business days). The fee covers SS-4 preparation, error checking, IRS fax filing, and email delivery.

Thai applicants choose between three filing paths. The table below compares them on cost and speed.

Method	Cost	Time	Notes
ein.so Standard	$49	4-7 business days	SS-4 prepared, error-checked, and faxed for you
ein.so Express	$97	2-3 business days	Priority handling and faster fax submission
DIY fax	$0	4-7 business days	You prepare and fax SS-4; errors cause silent rejection
DIY phone (267-941-1099)	$0	Same day	International call from Thailand during US business hours

The DIY fax method is free but unforgiving. A single formatting error on Line 4 or Line 7b causes the IRS to reject the application without notice. The phone method works the same day but requires an international call from Thailand during US business hours, with long hold times. See the full breakdown on EIN cost and EIN processing time.

No SSN Needed

Can Thai Applicants Get an EIN Without an SSN?

Yes. Thai applicants get an EIN without an SSN by entering their Thailand passport number on Form SS-4 Line 7b. No SSN, no ITIN, and no US residency is required. The IRS issues EINs to foreign responsible parties through the fax and mail channels.

The IRS online EIN tool is the fastest method, but it requires the responsible party to hold an SSN or ITIN. Thai applicants without an SSN cannot use the online tool. This is the single biggest point of confusion for non-residents.

Avoid these common Thai applicant mistakes

Trying the IRS online tool without an SSN. It blocks you after the first screen.
Leaving Line 7b blank. Enter your Thailand passport number, not "foreign" or "none."
Submitting a Thai address in local format. Reformat it to an IRS-accepted layout.
Listing a company as the responsible party. The IRS requires a person on Line 7a.

Many Thai founders confuse the EIN with an ITIN. The two are different. An EIN identifies your US business entity. An ITIN identifies you as an individual taxpayer. You do not need an ITIN to get an EIN. ein.so offers a separate ITIN service for $197 (Standard) or $297 (Express) if you later need one for personal US tax filing. See EIN without SSN and EIN for non-residents for full detail.

Banking & Payments

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

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

US Business Bank Account

Mercury, Relay, and Wise accept Thai 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. See EIN for Stripe.

PayPal Business (US)

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

Wise and Payoneer Transfers

Many Thai founders use Wise to move funds between their US account and a Thai bank account at the mid-market rate, converting to baht 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 your Thai bank when the USD/THB rate is favorable.

Tax Considerations

What Should Thai Entrepreneurs Know About US Taxes?

A single-member US LLC owned by a Thai resident is usually a disregarded entity for US federal income tax, so the LLC itself pays no US federal income tax on non-US-sourced income. The owner still files an annual information return. Confirm your exact position with a CPA.

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 necessarily a tax bill.

Thai Reporting

Thai residents generally must declare foreign income and foreign company interests to the Revenue Department of Thailand. Confirm your reporting duties for a foreign-held US LLC with a Thai tax advisor.

BOI Report to FinCEN

Most US LLCs must report beneficial ownership to FinCEN. Review the BOI filing rules to avoid penalties. The BOI report is free at fincen.gov/boi.
