EIN Vs ITIN Vs SSN For Non-US LLC Owners

Learn the difference between EIN, ITIN, and SSN for non-US LLC owners, and why many foreign-owned LLCs can apply for an EIN without an SSN or ITIN.

Need the business tax ID, not a personal tax ID? GatewayBase helps foreign-owned LLCs apply for an EIN.

EIN, ITIN, and SSN are different US tax IDs. Foreign LLC owners often confuse them because banks, IRS forms, and payment providers all ask for identification numbers.

For a US LLC, the company usually needs an EIN. The foreign owner may not need an SSN or ITIN just to apply for that EIN by Form SS-4.

Simple comparison

  • EIN: business tax ID for the company.
  • ITIN: personal tax ID for some people who need a US taxpayer number but cannot get an SSN.
  • SSN: personal Social Security Number, generally for US citizens and certain authorized individuals.

Do you need an ITIN to get an EIN?

Not always. Foreign LLC owners without an SSN or ITIN can often apply for an EIN using Form SS-4 and the foreign-owner path.

An ITIN may still be needed for other personal tax situations, but GatewayBase does not decide that and does not prepare ITIN applications.
