How Non-US Residents Can Legally and Quickly Obtain an EIN — Complete LLC/Corp Application Guide

Applying for an EIN as a non-US resident is challenging: the SS-4 form is complex, CP-575 is mailed only to US addresses, and even minor errors can cause rejections. Based on official IRS publications (Pub 1635, 583, ISS4, etc.), this guide explains the steps, pitfalls, and why SpeedEIN’s compliant services can get you your EIN in 7–10 business days and CP-575 in 20 days.

1. What is an EIN and Why Every LLC/Corp Must Have One?

According to the IRS’s Publication 1635, an EIN (Employer Identification Number) is a federal tax ID for businesses — essentially the company’s “tax identity card.” It’s required for tax filing, opening US bank accounts, hiring employees, issuing 1099 forms, and registering with payment processors like Stripe.
Publication 583 further notes that whether you are forming an LLC, Corporation, or Partnership, you must determine your tax classification and file the correct returns accordingly.
Specific rules for single-member LLCs with no employees are outlined on the IRS’s latest guidance pages.


2. The 5 “Hidden” Challenges for Non-US Residents Applying for an EIN

ChallengeDetailsConsequences
1. No online application optionThe IRS only allows US residents to apply online. Non-residents must fax or mail the SS-4.Process is slow, cumbersome, and prone to errors.
2. Strict formatting, high rejection rateThe SS-4 form has 18 sections and 35+ key fields. A single wrong entry or blank can trigger rejection without explanation.Delays of weeks or months.
3. CP-575 confirmation letter requires a US mailing addressThe IRS only mails the CP-575 to US addresses — not overseas.Without the CP-575, you can’t open a bank account or complete certain registrations.
4. Complex compliance requirementsMisstating the Responsible Party or using an agent’s info can violate IRS rules, potentially causing EIN revocation or triggering BOI (Beneficial Ownership Information) reporting issues.Legal and tax risks down the road.
5. Ongoing tax and record-keeping obligationsOnce you have an EIN, you must maintain proper records and file required returns. Neglect can result in penalties or cancellation of the EIN.Financial penalties, IRS audits.

Many non-US residents attempt a DIY EIN application and face these problems:
“I used a template from the internet and got rejected twice with no explanation.”
“I used a US friend’s address, and later the IRS froze my EIN until I filed BOI reports.”
