EIN for Non-US Residents: How to Get a US Business Tax ID

If you are a founder living outside the United States, getting an Employer Identification Number (EIN) is one of the most important early steps in building a U.S. business. An EIN is the federal tax ID used by the IRS to identify a business entity for tax filing, banking, payroll, and other compliance purposes.

For many non-US residents, the EIN process feels confusing because the IRS rules are different depending on where you live, what type of business you are forming, and whether your entity already exists. The good news is that non-US residents can obtain an EIN, and in many cases they can do so without a U.S. Social Security Number or U.S. address.

This guide explains what an EIN is, who needs one, how foreign founders can apply, what information you need, and how Zenind can help simplify the process.

What an EIN is and why it matters

An EIN is a nine-digit federal tax identification number assigned by the IRS. Think of it as the business equivalent of a tax ID used to identify your company in government records.

You may need an EIN to:

• Formally operate a U.S. LLC or corporation
• Open a business bank account
• Hire employees in the United States
• File federal tax returns
• Register for certain state tax accounts
• Apply for licenses, permits, or merchant accounts
• Separate business and personal financial activity

Even if your business has no employees, it may still need an EIN depending on the entity type and tax filing requirements.

Can non-US residents get an EIN?

Yes. Non-US residents can get an EIN for a U.S. business.

The exact application path depends on your situation. The IRS generally allows EIN applications online, by fax, by mail, or by phone for international applicants. In practice, foreign founders often use fax, mail, or telephone when they do not have a U.S. residence, U.S. principal office, or taxpayer identification number that fits the online process.

If you are forming a U.S. company from abroad, you do not need to wait until you are physically in the country to start the EIN process.

When a non-US resident may need an EIN

You may need an EIN if you are:

• Forming a U.S. LLC as a foreign founder
• Launching a corporation in the United States
• Opening a business bank account for a U.S. entity
• Hiring U.S.-based employees or contractors
• Filing partnership or corporate tax returns
• Registering for state tax accounts
• Applying for an ITIN-linked business structure or other federal filings

If your business is active in the United States, the EIN is often one of the first compliance items to secure.

How non-US residents can apply for an EIN

The IRS offers several filing methods, but not every method is equally practical for foreign applicants.

1. Online application

The online EIN application is generally the fastest option, but it is primarily designed for applicants with a legal residence, principal place of business, or principal office in the United States or U.S. territories.

If you qualify, online filing can produce an EIN quickly and immediately after the application is completed.

2. Fax application

Fax is a common option for international applicants. You complete Form SS-4 and fax it to the IRS using the appropriate international filing path.

For foreign founders, fax filing is often preferred because it is straightforward, does not require a U.S. mailing address, and can return the EIN faster than mail.

3. Mail application

Mail is available, but it is usually the slowest option. If you are outside the United States and do not need the EIN urgently, mail can still work, but the processing time is longer.

4. Phone application for international applicants

International applicants may also be able to obtain an EIN by phone through the IRS. This is generally available only to applicants outside the United States and U.S. territories.

The IRS representative uses the information on Form SS-4 to assign the EIN during the call.

What you need before applying

Before you start, gather the business details the IRS will ask for. Having everything ready will reduce delays and avoid unnecessary corrections.

You will typically need:

• Legal name of the entity
• Trade name, if applicable
• Entity type, such as LLC or corporation
• Mailing address
• Country of formation, if foreign
• Responsible party information
• Reason for applying
• Date the business was started or acquired
• Number of employees expected in the next 12 months
• Primary business activity
• Name and title of the person authorized to sign the form

If you are a foreign applicant, you may not have an SSN or ITIN. That does not automatically block the application, but you should be prepared to identify the responsible party and complete the form carefully.

Step-by-step: How to get an EIN as a non-US resident

Step 1: Form your U.S. business entity

If you are creating an LLC or corporation, the entity should be formed first through the appropriate state filing process before or alongside the EIN application.

The IRS wants the legal entity information to match the registration records as closely as possible.

Step 2: Complete Form SS-4

Form SS-4 is the IRS application for an EIN. This form asks for basic business identity details, the responsible party, and the reason for applying.

Accuracy matters. Incomplete or inconsistent entries can delay processing, especially for foreign applicants.

Step 3: Choose the filing method

Select the method that matches your situation:

• Online, if you qualify as a U.S.-based applicant
• Fax, if you are outside the U.S. and want a faster paper filing option
• Mail, if timing is less urgent
• Phone, if you are an international applicant and the IRS phone process is available to you

Step 4: Submit the application

Once the form is completed, submit it through the selected filing channel.

If the IRS needs clarification, be ready to respond quickly. Small errors, such as mismatched names or incomplete responsible party information, can cause delays.

Step 5: Save the EIN assignment notice

Once the EIN is issued, keep the confirmation notice with your company records. You will likely need it to open financial accounts, register for tax accounts, and complete other compliance tasks.

Common mistakes non-US residents should avoid

Foreign founders often run into the same preventable issues. Avoid these mistakes:

• Using a personal name where the legal entity name is required
• Entering inconsistent addresses across state, IRS, and banking documents
• Choosing the wrong entity type on Form SS-4
• Forgetting to identify the responsible party correctly
• Applying before the business entity is properly formed
• Using an old or unsupported application method
• Leaving required fields blank when a more specific entry is needed

A careful review before submission can save time and keep your setup moving.

How long it takes to get an EIN

Processing time depends on the filing method.

• Online applications can be immediate for eligible applicants
• Fax applications are often processed faster than mail
• Mail applications take the longest
• Phone applications for international applicants may result in quicker assignment when available

If you are forming a business from abroad, timing matters because the EIN may be needed for banking, tax registration, and vendor onboarding.

What to do after you receive your EIN

Getting the EIN is an important milestone, but it is not the final step in U.S. business compliance.

After you receive it, you may still need to:

• Open a business bank account
• Register for state tax accounts, if required
• Obtain business licenses or permits
• Set up payroll if you plan to hire employees
• Track annual and quarterly tax deadlines
• Maintain proper business records
• File required informational and income tax forms

Your obligations depend on your entity type, where you operate, and whether you have employees or taxable activities.

Why EINs matter for foreign-owned U.S. companies

An EIN is more than a formality. It helps establish your company as a real operating business in the United States.

Without it, you may face delays when trying to:

• Open accounts
• Sign up with payment providers
• Register for tax purposes
• Submit state filings
• Work with professional service providers

For non-US residents, the EIN often connects company formation, tax compliance, and banking into one streamlined setup process.
