Can I submit Form SS-4 via the online EIN assistant in 2026 if I lack an SSN?

No, you cannot use the IRS online application system without a valid Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). In 2026, foreign applicants without these identifiers must use the manual paper-based process. This involves submitting a physical Form SS-4 via fax or mail to the IRS. The online portal is strictly reserved for applicants who can be verified through domestic tax ID numbers, meaning international founders must prepare for a 4 to 8 week manual processing window.

Which specific information should I enter on Line 7b of Form SS-4 in 2026?

On Line 7b of the 2026 version of Form SS-4, you must write the word Foreign if you do not have an SSN or ITIN. This tells the IRS that the responsible party is a non-resident alien who is not yet required to have a US personal tax identification number. Leaving this line blank or entering N/A will result in your application being rejected. Ensure Line 7a contains the full legal name of the individual responsible for the entity to match your passport exactly.

How long does a 2026 EIN application take when filing by international fax?

A 2026 EIN application submitted via the international fax number (currently 1-304-707-9471) typically takes 15 to 20 business days to process. However, during peak filing seasons between January and April, the wait times often extend to 45 days. If you choose to mail the application instead of faxing it, the IRS warns that processing can take up to 60 days due to mail transit and manual data entry requirements at the Cincinnati service center.

What happens if my 2026 EIN application is rejected for an invalid address?

If the IRS rejects your 2026 application because of an invalid address, you must provide a physical address or a valid registered agent address in the state of formation. The IRS does not allow the use of P.O. boxes or purely virtual mailboxes on Line 4 of Form SS-4. You will receive a CP 575 notice or a rejection letter explaining that the address provided does not meet the criteria for a principal place of business, requiring a resubmission of the corrected form.

How to Get an EIN Without an SSN or ITIN in 2026

To get an EIN without an SSN or ITIN in 2026, you must submit a completed Form SS-4 to the IRS via fax or mail with the word Foreign entered on line 7b. This manual application process allows non-resident founders to obtain a tax ID by designating a responsible party who does not hold US citizenship or residency. Once processed, the IRS will issue a 9 digit Employer Identification Number that enables you to open business bank accounts and meet federal filing requirements.

Why founders need an EIN in 2026

An Employer Identification Number (EIN) is the primary identifier for your business entity in the eyes of the Internal Revenue Service. Even if you do not plan to hire employees immediately, an EIN is mandatory for US business formation activities such as opening a Mercury or Relay bank account, applying for a payment processor like Stripe, and filing annual tax returns. In 2026, the global banking system has tightened compliance, making the EIN the absolute baseline for any entity wishing to operate in the US market.

How do I fill out Form SS-4 without a US tax ID?

Filling out Form SS-4 while lacking a Social Security Number requires precision to avoid a systemic rejection. The most critical section for international founders is Line 7. On Line 7a, you must provide the name of the responsible party (the individual owner or a high level officer). On Line 7b, instead of a numeric ID, you must clearly write the word Foreign.

On Line 9a, you should check the box for the type of entity you have formed, such as a Limited Liability Company (LLC) or a Corporation. In 2026, if you are a single member LLC, you may also need to specify if the entity is a disregarded entity for tax purposes. Error rates on these lines are the leading cause of delays for non-resident applications.

What is the 2026 process for faxing the IRS?

The IRS maintains a specific fax line designated for international applicants. In 2026, the preferred method for founders without an SSN is to fax the completed and signed Form SS-4 to 1-304-707-9471. Unlike the domestic online portal which provides a number instantly, the fax method requires an IRS agent to manually input your data.

Application Method	Typical Wait Time (2026)	Requirement
Online Assistant	Instant	Requires SSN or ITIN
Phone (International)	30 to 60 minutes hold	Only for foreign-formed entities
Fax (International)	4 to 5 weeks	Form SS-4 with 'Foreign' on 7b
Mail (Cincinnati, OH)	8 to 10 weeks	Original signature required

Can a third party obtain an EIN for me?

You can designate a third party designee to act on your behalf to obtain the EIN. This is often the most efficient route for international founders who do not want to navigate the complexities of IRS faxing. By completing the Third Party Designee section at the bottom of Form SS-4, you authorize an agent to receive the EIN and answer questions about the application. This authorization expires as soon as the EIN is issued and the notice is mailed to you.

What happens after the EIN is issued?

Once the IRS assigns your number, you will receive a CP 575 or a 147C letter. This document is the official proof of your EIN. You will need this physical or digital copy to verify your business with financial institutions. In 2026, banks are increasingly requiring the 147C letter specifically because it is a direct confirmation from the IRS database, reducing the risk of identity fraud.

Once you have your EIN, you must also ensure your business complies with the Corporate Transparency Act by filing your Beneficial Ownership Information (BOI) report within 90 days of formation. The EIN is a required field on this federal report. Failure to link your EIN to your BOI filing can lead to significant daily penalties under 2026 enforcement rules.

2026 EIN Application Checklist

Verify Entity Name: Ensure the name on Form SS-4 matches the Articles of Organization exactly.
Sign and Date: The form must have a wet signature; some IRS agents in 2026 still reject purely digital signatures that do not meet e-file security standards.
Secure a US Address: Have a registered agent or physical business address ready for Line 4.
Prepare for Faxing: Use a digital fax service that provides a confirmation receipt for your records.
Plan for ITIN: While you do not need an ITIN for the EIN, you may need one later for personal tax filings or to claim treaty benefits.
