You do not need a Social Security Number to get a U.S. tax ID. That single misconception stops thousands of Serbian and Eastern European entrepreneurs from ever starting their U.S. LLC. The Employer Identification Number (EIN) is a 9-digit identifier issued by the IRS in the format XX-XXXXXXX, and it works like a Social Security Number but for your business. Non-residents can apply from anywhere in the world, no U.S. address required. This guide walks you through what the EIN is, who needs one, how to apply from abroad, and how to stay compliant once you have it.

What is a U.S. tax ID (EIN)?
Now that you know you don’t need to be a U.S. resident, let’s clarify what a U.S. tax ID really means.
The term “U.S. tax ID” covers several types of identification numbers, but for LLC owners, one number matters most: the Employer Identification Number, or EIN. The IRS issues the EIN to identify businesses for federal tax purposes, making it functionally similar to a Social Security Number (SSN), but assigned to an entity rather than an individual.
Here’s what makes the EIN unique for foreign founders: non-U.S. residents can obtain an EIN for a U.S. LLC without an SSN, an Individual Taxpayer Identification Number (ITIN), or any form of U.S. residency. No citizenship requirements apply. That means a founder sitting in Belgrade, Bucharest, or Warsaw can fully identify their U.S. business to the IRS.

Why the EIN matters so much
Many founders think the EIN is just a tax form number. It’s actually the key that unlocks your U.S. business infrastructure. Without an EIN, you cannot:
- ✅ Open a U.S. business bank account (Mercury, Relay, or traditional banks)
- ✅ Set up payment processors like Stripe or PayPal for your LLC
- ✅ File your annual federal tax returns
- ✅ Hire employees or pay U.S. contractors legally
- ✅ Apply for U.S. business licenses and permits
- ✅ Build business credit history in the U.S.
The LLC registration overview process and the EIN application are two separate steps, but they are tightly connected. You register your LLC first, then you apply for the EIN using your newly formed business name and registration details. Trying to get them simultaneously or in the wrong order creates delays and mismatches that the IRS will flag.
“The EIN is not an optional add-on for your LLC. It is the foundation of your U.S. business identity. Every major compliance action your company takes will reference this number.”
One more important clarification: the EIN does not expire, and you do not need to renew it annually. Once issued, it belongs to your LLC permanently. However, if you dissolve the LLC and later form a new one, the new entity requires a new EIN. The number follows the entity, not the owner.
Who needs a U.S. tax ID and why?
With the basics clear, let’s discuss exactly who needs a U.S. tax ID and why it’s an essential step.
If you own or plan to own a U.S. LLC as a non-resident, you need an EIN. That applies whether you are a solo founder from Serbia, a two-person team from Romania, or a group of partners from across Eastern Europe. The IRS treats all foreign-owned single-member LLCs (SMLLCs) as disregarded entities for federal tax purposes, but that does not mean you are invisible to the IRS. It means your LLC’s income and expenses are reported on specific forms, and the EIN is required to file them.
Common scenarios where your EIN is required
- Opening a U.S. bank account. Banks like Mercury and Relay are popular with non-resident LLC owners because they operate online and accept foreign founders. However, every bank requires your EIN before opening the account.
- Accepting online payments. Stripe and PayPal require your EIN for business account verification. Without it, your account may be limited or suspended.
- Filing annual IRS returns. Even if your LLC earns zero revenue in a given year, you may still be required to file. The EIN is required on every form.
- Hiring U.S.-based employees or contractors. Payroll processing, W-2s, and 1099 forms all reference your EIN.
- Applying for certain business licenses. State-level business licenses in many states require a federal EIN before they can be issued.
Addresses: what you actually need
A common worry is whether you need a U.S. address to apply. The answer is no. The IRS accepts a foreign address on the EIN application. However, for banking purposes specifically, having a U.S. registered agent address associated with your LLC strengthens your application with banks and payment processors.
The non-residents LLC guide covers this in more detail, but the short version is: use your registered agent’s address for the LLC’s public records and your own foreign address for IRS correspondence.
Pro Tip: Review the common mistakes non-residents make when applying for their EIN. One of the most frequent errors is entering the wrong entity type on Form SS-4, which can delay the issuance of your EIN by weeks. Spend five minutes double-checking your form before submitting.
You do not need to visit the U.S. at any point in this process. From forming your LLC to receiving your EIN to opening a bank account online, the entire workflow is achievable without ever boarding a plane.
How non-U.S. owners can apply for a U.S. tax ID
Once you know you need an EIN, here’s how to actually get it from abroad, step by step.
The application process for non-U.S. residents is straightforward, but it differs from what U.S.-based owners use. The online EIN application on the IRS website requires an SSN or ITIN and a U.S. principal place of business, so that route is closed for most foreign founders. Instead, you have three options: phone, fax, or mail.
Step-by-step application process
- Form your LLC first. Before applying for an EIN, your LLC must be officially registered in a U.S. state. Start by reading the how to start a U.S. LLC guide for non-residents if you haven’t done this yet.
- Download Form SS-4. This is the official IRS application for an EIN. You can find it on the IRS website.
- Complete Form SS-4 as a non-resident. On line 7b (asking for your SSN, ITIN, or EIN), write “Foreign” if you have none. Fill out your LLC’s legal name exactly as it appears on your state formation documents.
- Choose your application method. Select the method that matches your timeline.
- Submit and receive your EIN. Once issued, record it securely. You will use it on every tax form and banking application your LLC ever files.
EIN application methods compared
| Method | Processing time | Best for |
|---|---|---|
| Phone (+1-267-941-1099) | Immediate | Fastest results, time-sensitive banking |
| Fax | Approximately 4 days | When phone isn’t practical |
| 4-5 weeks | No urgency, paper trail preferred |
The EIN for foreign-owned LLCs confirms that applying by phone provides an immediate EIN at the end of the call, while fax takes around 4 days and mail can stretch to 4-5 weeks. If you need to open a bank account quickly, phone is the clear choice.
Pro Tip: When calling the IRS international line, be prepared. Have your completed Form SS-4 in front of you. The IRS agent will ask for the information on that form verbally. The call typically takes 20 to 30 minutes. Call during U.S. business hours (Monday through Friday, 6 AM to 11 PM Eastern Time).
For Serbian and Eastern European founders specifically, the registration guide for non-residents walks through the state registration process in detail. Delaware and Wyoming are the two most popular states for non-resident LLCs because of their low fees, privacy protections, and straightforward compliance requirements.
Maintaining compliance: Annual filings and penalties
After securing your EIN, it’s vital to stay compliant annually to avoid severe penalties.
Getting your EIN is step one. Keeping your LLC in good standing with the IRS is the ongoing responsibility that many foreign founders underestimate. For foreign-owned single-member LLCs, the IRS has specific annual filing requirements that apply even if your LLC earned no revenue during the year.
What you must file every year
- Pro forma Form 1120. This is a simplified corporate tax return used as a cover sheet for your annual filing. It is not the standard Form 1120 used by corporations, but a modified version required for foreign-owned SMLLCs.
- Form 5472. This form reports transactions between your LLC and its foreign owner. A “reportable transaction” includes contributions you make to the LLC, distributions you take from it, and any loans between you and the business.
- State-level annual reports. Separate from IRS requirements, most U.S. states require an annual report and fee to keep your LLC active. Fees range from $0 in states like New Mexico to several hundred dollars in others.
What counts as a reportable transaction?
This is where many founders are surprised. You do not need to sell products or earn revenue for a reportable transaction to exist. If you funded your LLC from your personal account, that is a reportable contribution. If you paid yourself from the LLC, that is a reportable distribution. The IRS wants a full accounting of money movement between you and your U.S. entity.
Important: The Form 5472 penalty is $25,000 per form, per year. If you file late or fail to file entirely, that penalty applies automatically. For a two-year lapse, you are looking at $50,000 in penalties before any other costs.
The LLC tax filing for non-residents guide covers the mechanics of both forms in plain language. The filing deadline is April 15, but you can request an extension to October 15 using Form 7004. Extensions apply to the filing deadline, not to any taxes owed.
For a comprehensive look at everything beyond Forms 5472 and 1120, the complete guide to LLC tax filing covers state taxes, sales tax obligations, and how multi-member LLCs are treated differently.
Key compliance dates to track:
- April 15: Annual filing due date for Forms 1120 and 5472
- October 15: Extended filing deadline (after Form 7004 approval)
- Varies by state: Annual report due dates for your LLC’s home state
What most guides miss about U.S. tax IDs for non-residents
Here is something we see constantly: founders from Serbia and Eastern Europe spend weeks researching the EIN application and then treat annual compliance as an afterthought. The EIN process, while unfamiliar, is actually the easier part. The phone call to the IRS takes 30 minutes. Getting it right consistently, year after year, is where the real work is.
Most guides lead with how simple it is to get started, and that’s true. But they don’t tell you that a missed Form 5472 filing costs more than many founders earn in their first year of U.S. business. The $25,000 penalty is not a scare tactic. It is an automatic assessment.
The smarter approach is to learn the basics of compliance even if you plan to outsource the actual filing. Knowing what Form 5472 captures, what triggers a reportable transaction, and when your state annual report is due means you can catch errors before they become penalties. Outsourcing without understanding is how founders end up blindsided. Reading guides like avoiding costly mistakes gives you the context to ask better questions of whoever handles your filings.
The EIN opens the door. Compliance keeps it open.
