How do I get an EIN for my US company if I don't have an SSN or ITIN?

Checked on

The IRS online EIN application needs the responsible party's SSN or ITIN and a US principal place of business. Without them, file Form SS-4 and write "foreign" or N/A on line 7b. International applicants can call 267-941-1099, fax it (EIN generally within 4 business days) or mail it (about 4 weeks). The EIN is free.

Why the online tool won’t work for you

The IRS online application issues an EIN immediately, but only if the entity was formed in the US, its principal place of business is in the US, and the responsible party has an SSN or ITIN. The Form SS-4 instructions say that if you have no legal residence, principal place of business or principal office in the US, you can’t use it and must apply another way.

Filling in Form SS-4 without an SSN

The “responsible party” on line 7a/7b must be an individual, not a company. Normally you enter their SSN or ITIN; if they don’t have one and aren’t eligible for one, the instructions say to enter “foreign” or N/A on line 7b. An entry is required.

For a single-member LLC owned by a foreign person that needs an EIN to file Form 5472, the instructions say to check “Other” on line 9a and write “Foreign-owned U.S. disregarded entity-Form 5472”, and on line 10 write “Foreign-owned U.S. disregarded entity filing Form 5472”.

The three ways to apply from abroad

Does a single-member LLC need its own EIN?

The IRS says most new single-member LLCs classified as disregarded entities will need one. One with no employees and no excise tax liability doesn’t need an EIN for federal tax, but can get one if it needs it to open a bank account or because state law requires it. A foreign-owned single-member LLC uses its own EIN to file Form 5472.
