What an EIN is
EIN stands for Employer Identification Number. It is the federal tax ID the IRS gives a business, a bit like a social security number for your company.
You can get an EIN for your US LLC even if you live outside the US and have no Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN).
Why you cannot use the online IRS form
The IRS online tool only works if your principal place of business is in the US or a US territory, and if the responsible party has an SSN or ITIN.
If you run your LLC from abroad or have no SSN or ITIN, you apply with Form SS-4 instead. International applicants can send it by fax or post, or give the details to the IRS by phone.
What to write on line 7a and 7b
On line 7a, enter the name of the person who ultimately owns or controls the business. The IRS calls this person the responsible party. It must be a person, not another company.
On line 7b, write "Foreign" or "N/A" if that person has no SSN or ITIN and is not eligible to get one. Do not leave the line empty and never make up a number.
How to send Form SS-4
Complete and sign Form SS-4, then send it to the fax number or postal address in the IRS instructions for applicants outside the US. International applicants can also call the IRS on +1 267-941-1099 (not toll-free).
Keep a copy of the signed form and proof that you sent it. The IRS sets the processing time, so allow for the wait when you plan your launch.
Common mistakes to avoid
Use the LLC's exact legal name from its formation documents, and list the real owner as the responsible party. If a formation service applies for you, the form must name it as third party designee and you must sign it.
Check your contact details and signature before you send the form. If you are waiting for a reply, do not send a second application: duplicate forms can slow things down.
What you can do with your EIN
Keep the IRS confirmation letter safe. Banks will ask for the EIN together with your company documents and proof of identity when you open a business account.
Payment platforms such as Stripe and marketplaces such as Amazon also ask for your EIN when you sign up as a US company. Each one runs its own checks.
If you own a single-member US LLC from abroad, speak to a US accountant about Form 5472 and your yearly deadlines.
