Do You Need an SSN to Form a U.S. LLC?

No. You do not need a Social Security Number (SSN) to form a U.S. LLC. Non-residents without an SSN can form an LLC and obtain an EIN using a different IRS process. The LLC formation itself requires only a state filing. The EIN application requires either a fax submission of Form SS-4 or a call to the IRS international line.
This is one of the most common questions from foreign founders exploring U.S. business formation. The short answer is no. The longer answer involves understanding which steps require an SSN and which do not, and what your options are at each stage.
FORMING THE LLC: NO SSN REQUIRED
LLC formation is a state-level process. You file Articles of Organization with the state, pay the filing fee, and appoint a registered agent. None of these steps require an SSN or ITIN. States only require basic information: your LLC name, your registered agent's address, and your signature.
Non-residents in every U.S. state can form an LLC without any U.S. tax identification number. This includes Wyoming, New Mexico, Delaware, Florida, and every other state.
GETTING AN EIN WITHOUT AN SSN
An EIN (Employer Identification Number) is issued by the IRS and is required to open a U.S. business bank account, hire employees, and file U.S. tax returns. The standard online EIN application on the IRS website requires an SSN or ITIN for the responsible party. Non-residents without either must use an alternative method.
There are two IRS-approved methods for non-residents:
Fax Form SS-4: Complete IRS Form SS-4 and fax it to the IRS at +1 (855) 641-6935. Processing takes 4 to 6 weeks. The EIN is mailed to the address on the form.
IRS International Phone Line: Call +1 (267) 941-1099, Monday through Friday, 6am to 11pm Eastern. A responsible party who can communicate in English must be available. The EIN is issued during the call.
CPA NOTE
The responsible party on Form SS-4 must be a real person, not a company or trust. For a single-member LLC owned by a foreign individual, that person is the responsible party. Their name and foreign address are entered on the form. No U.S. address is required for the responsible party.
OPENING A BANK ACCOUNT WITHOUT AN SSN
Traditional U.S. banks (Chase, Bank of America, Wells Fargo) typically require an SSN or ITIN to open a business account, plus an in-person visit. This is the most common barrier non-residents face after formation.
Fintech alternatives that do not require an SSN:
Mercury Bank: Accepts foreign-owned LLCs with EIN and formation documents. No SSN required. Fully remote application.
Relay: Similar to Mercury. Works for non-residents with a valid EIN and Articles of Organization.
Wise Business: Multi-currency account. Not a full U.S. bank account but useful for international payments.
Stripe Atlas: Includes a Mercury account. Requires Stripe as your primary payment processor.
IMPORTANT
You must have your EIN before applying for a bank account. Banks require it as part of the application. Do not attempt to open a bank account using only your LLC formation documents without an EIN.
FILING U.S. TAXES WITHOUT AN SSN
A foreign-owned single-member LLC must file Form 5472 annually. This form reports transactions between the LLC and its foreign owner. It is filed as an attachment to a pro forma Form 1120.
Form 5472 filing does not require an SSN. It uses the LLC's EIN. However, if the foreign owner needs to file a U.S. personal tax return (for example, if the LLC generates income effectively connected to a U.S. trade or business), an ITIN may be required for the owner separately.
DO NOT SKIP THIS FILING
Form 5472 is mandatory for every foreign-owned single-member LLC, even with zero revenue. The IRS penalty for a missing or late filing is $25,000 per year, automatic, regardless of income. Most non-residents first hear about Form 5472 after receiving a penalty notice.

FREQUENTLY ASKED QUESTIONS
Can I get an ITIN instead of an SSN to form an LLC?
An ITIN (Individual Taxpayer Identification Number) is a tax processing number issued by the IRS to individuals who are not eligible for an SSN. An ITIN can be used on Form SS-4 for the EIN application as an alternative to an SSN. However, an ITIN is not required to form the LLC itself. You can form the LLC and apply for the EIN without any U.S. tax ID.
How long does it take to get an EIN without an SSN?
By fax: 4 to 6 weeks. By phone (IRS international line): same day, during the call. The phone method is faster but requires a responsible party who can communicate in English and be available during U.S. business hours.
Do I need an SSN to be a member of a U.S. LLC?
No. There is no requirement for LLC members to have an SSN. Foreign individuals, foreign corporations, and foreign trusts can all be members of a U.S. LLC without any U.S. tax identification number at the time of formation.
Will I eventually need an SSN or ITIN?
Possibly. If your LLC generates income that is effectively connected to a U.S. trade or business, you may need to file a U.S. personal tax return as a non-resident alien (Form 1040-NR), which requires an ITIN. For most passive or online businesses with no U.S. physical presence, the LLC files Form 5472 using only the EIN and no personal U.S. tax ID is required.
Can a formation service get my EIN without my involvement?
Not fully. The IRS requires the responsible party to either sign Form SS-4 (for fax submissions) or be available by phone (for the international line). A formation service can prepare the form and manage the process, but the foreign owner must sign or participate. Services that claim to obtain EINs entirely on your behalf without your signature should be verified carefully.
