If you’re a Serbian or Eastern European entrepreneur forming a U.S. LLC, you’ve probably heard that getting an EIN is complicated, or worse, that it’s only available to U.S. residents. Neither is true. An Employer Identification Number is a 9-digit federal tax ID issued by the IRS to businesses for tax purposes, similar to a Social Security Number for companies, and any non-resident forming a U.S. LLC can apply for one. This guide breaks down exactly what an EIN is, who qualifies, how to apply from Serbia or Eastern Europe, and what to do once you have it.

What is an EIN and why does it matter for non-residents?
An EIN, or Employer Identification Number, is the IRS’s way of identifying your business for tax purposes. Think of it as your company’s official ID with the federal government. Without it, your U.S. LLC exists legally on paper but can’t function properly in the real world.
“An EIN is to your business what a Social Security Number is to an individual. It’s the identifier that makes your company visible and legitimate to U.S. financial institutions, payment processors, and government agencies.”
Here’s why every non-resident LLC owner needs to understand this number:
- ✅ Banking: You need an EIN to open a U.S. business bank account. No bank will process a business account application without it.
- ✅ Payment processing: Platforms like Stripe, PayPal, and Merchant accounts require an EIN to verify your business identity.
- ✅ Hiring employees: If you ever plan to hire U.S.-based staff, an EIN is mandatory for payroll tax reporting.
- ✅ Federal tax filings: Your LLC’s annual tax obligations with the IRS are tied directly to your EIN.
- ✅ Vendor and contractor relationships: Many U.S. vendors and contractors require your EIN before issuing a contract or payment.
A critical point: citizenship and residency are not requirements. The IRS does not ask where you live. What matters is that you have a legally formed U.S. LLC and a responsible party to list on the application. You can learn more about managing this as a foreign owner LLC basics before you apply.
Pro Tip: Many Serbian and Eastern European founders delay getting their EIN because they assume they need to first get an ITIN or SSN. You don’t. The EIN application for non-residents is a separate process entirely, and you can pursue it immediately after your LLC is formed.
Two myths are worth addressing directly. First, that only U.S. residents or citizens qualify. False. The IRS explicitly allows non-resident individuals to apply for an EIN for their U.S. LLC. Second, that the process is extremely complex and requires legal representation. Also false. The application process is standardized. With the right preparation, most non-resident founders complete it without any legal assistance.
If you want a detailed breakdown of what the EIN for your U.S. LLC process involves at each stage, we’ve put together a resource specifically for non-resident owners covering every scenario.
Who needs an EIN? Eligibility for Serbian and Eastern European owners
With an understanding of what an EIN is, let’s clarify if you are eligible as a Serbian or Eastern European owner.
The short answer: yes, you qualify. The IRS does not discriminate based on nationality, residency status, or location. If you are starting a U.S. LLC, you are eligible to apply for an EIN, full stop.
Here’s a clear overview of what is and is not required:
| Requirement | Required for EIN? |
|---|---|
| U.S. citizenship | ❌ No |
| U.S. residency | ❌ No |
| U.S. mailing address | ❌ No |
| Social Security Number (SSN) | ❌ No |
| Individual Taxpayer Identification Number (ITIN) | ❌ No |
| Legally formed U.S. LLC | ✅ Yes |
| Responsible party (individual or entity) | ✅ Yes |
| Valid foreign address | ✅ Yes |
Serbian and Eastern European applicants follow the same process as any other non-resident. There are no additional documentation requirements, no separate application form, and no extra processing fees. The U.S. tax ID details that apply to a Canadian applicant apply equally to someone based in Belgrade, Bucharest, or Budapest.
One practical consideration worth noting: the IRS phone line for EIN applications operates Monday through Friday from 6 AM to 11 PM Eastern Time. For Serbian and Eastern European owners, that’s a 6 to 8 hour time difference, which means the available calling window falls between roughly midnight and 5 PM local time. This is a scheduling reality, not an eligibility barrier.
Who specifically needs an EIN?
- ✅ Non-resident founders of single-member U.S. LLCs
- ✅ Multi-member LLC owners operating from abroad
- ✅ Any LLC that has hired or plans to hire employees in the U.S.
- ✅ LLCs that file certain federal tax forms (such as Form 5472 combined with Form 1120)
- ✅ LLCs opening U.S. bank accounts or using U.S. payment platforms
- ✅ LLCs entering contracts with U.S. businesses requiring a tax ID
If your LLC falls into any of these categories, getting your EIN early is the right move. Delaying it creates bottlenecks when you try to open a bank account or set up payment processing.
How non-residents can apply: Step-by-step EIN process
Once you know you’re eligible, the next logical step is understanding how to actually apply for your EIN as a non-resident. There are three methods available: phone, fax, and mail. Each has pros and cons depending on your situation and how quickly you need the number.
Method 1: Phone application (fastest)
This is the most efficient method for most non-resident founders. You call the IRS directly, answer questions in real time, and receive your EIN at the end of the call.
Steps:
- Form your U.S. LLC first. You cannot apply for an EIN before your LLC is officially formed.
- Complete Form SS-4 in advance. Even for a phone call, you’ll be asked for the same information.
- Call the IRS Business & Specialty Tax Line at +1-267-941-1099 (for international callers).
- Be prepared to answer questions about your LLC: legal name, business address, type of entity, reason for applying, and responsible party information.
- Receive your EIN verbally at the end of the call and follow up with a written confirmation.
Key timing note: The IRS phone line is open Monday through Friday, 6 AM to 11 PM Eastern Time. For Serbian founders, that’s roughly 12 AM to 5 PM local time. Planning your call during your early morning hours maximizes your window.
Method 2: Fax application (moderate speed)
This works well if phone calls are inconvenient or if you’re coordinating across multiple time zones.
Steps:
- Complete Form SS-4 in full. Download it from the IRS website.
- Fax it to 855-641-6935 (U.S. domestic) or check IRS guidelines for international fax numbers.
- Wait 4 business days. The IRS will fax your EIN back to the number you provide.
Pro Tip: Include a cover sheet with your name and contact information. Missing information on your Form SS-4 will delay processing.
Method 3: Mail application (slowest)
Mail is an option, but it comes with a significant wait time.
Steps:
- Complete Form SS-4.
- Mail it to the IRS at: Internal Revenue Service, Attn: EIN Operation, Cincinnati, OH 45999.
- Allow 4 to 8 weeks for processing and delivery of your EIN by return mail.
Here’s a comparison to help you decide:
| Application method | Speed | Best for |
|---|---|---|
| Phone | Same day | Founders who need the EIN urgently |
| Fax | 4 business days | Those who can’t call during IRS hours |
| 4 to 8 weeks | Non-urgent situations with no fax access |
Statistic callout: The majority of non-resident LLC owners who work with professional formation services choose phone or fax applications to avoid the 4 to 8 week mail delay, especially when bank account opening is time sensitive.
Common mistakes that slow things down:
- ❌ Applying before your LLC is officially formed
- ❌ Leaving fields blank on Form SS-4
- ❌ Listing an incorrect responsible party (must be an individual, not the LLC itself for non-residents)
- ❌ Using a P.O. box when a physical address is required
- ❌ Calling outside IRS business hours
For a broader look at what the U.S. business formation process involves before and alongside your EIN application, including registered agent setup and state filings, we’ve covered each step in detail.
Once you have your EIN, you’ll also want to understand your LLC tax filing for non-residents, since your EIN is the anchor for all federal reporting obligations going forward.
After you get your EIN: What non-residents should do next
Once you’ve obtained your EIN, there are key next steps to take to ensure smooth business operations and compliance. Getting the number is only the beginning. What you do immediately after determines how well your LLC functions in the U.S. market.
An EIN from the IRS is your 9-digit federal tax ID, and every action below depends on having it in hand.
Priority actions after receiving your EIN:
- ✅ Open a U.S. business bank account. Most U.S. banks require your EIN, LLC formation documents, and a valid ID. Some banks allow non-resident founders to open accounts online or through a third-party service.
- ✅ Set up payment processing. Platforms like Stripe, PayPal Business, and others will ask for your EIN during account verification.
- ✅ Review federal reporting obligations. Foreign-owned single-member LLCs must file Form 5472 attached to Form 1120 each year. Missing this filing carries a $25,000 penalty.
- ✅ Check your state’s annual report requirements. Most states require an annual report and a registered agent on file. These are separate from federal obligations.
- ✅ Use your EIN on contracts and invoices. Any U.S. business partner may ask for your EIN for 1099 reporting purposes.
Pro Tip: Store your EIN confirmation letter (CP 575) in a secure location. Banks and agencies will ask for it repeatedly, and replacing it requires a specific request to the IRS that can take weeks.
Your LLC tax reporting obligations begin in the first tax year your LLC is active, regardless of whether you generated revenue. Non-resident owners are often surprised to learn that a “zero revenue” year still requires a filing. Staying on top of IRS forms for non-residents from the start protects you from penalties and keeps your LLC in good standing.
What most guides miss: The real challenges for Serbian and Eastern European founders
You’ve learned the practical steps. Here’s some industry perspective based on working with thousands of non-resident applications across Serbia and Eastern Europe.
The most consistent finding is this: the EIN process itself is rarely the problem. It is standardized, well-documented, and more accessible than most founders expect. What creates real friction is almost never eligibility or paperwork. It’s logistics and what comes after.
The time zone gap is the most underrated obstacle. When the IRS phone line opens at 6 AM Eastern, it’s midnight or later in Belgrade, Sarajevo, or Bucharest. Founders who underestimate this end up missing their calling window repeatedly, adding days or weeks to their timeline. The fix is simple: plan ahead, set an alarm, and treat that call like a scheduled business meeting. Alternatively, fax is your friend.
There’s also a persistent overestimation of what you need to have in place before applying. Many Serbian and Eastern European entrepreneurs spend weeks trying to get an SSN, ITIN, or U.S. address before they even attempt the EIN application. That preparation is wasted effort. The IRS eligibility rules for non-residents require none of those things. Your Serbian or Romanian address, your foreign passport, and your LLC formation documents are sufficient.
What is genuinely underestimated is compliance after the EIN. Getting the number feels like the finish line, but it’s actually the starting line. Annual filings, Form 5472, state reports, registered agent maintenance: these are the obligations that trip up non-resident founders who don’t have a support system in place. We’ve seen LLCs accumulate significant IRS penalties simply because the founder didn’t know about Form 5472, or missed a state annual report deadline.
If you want to avoid the most costly mistakes non-resident founders make after formation, reviewing the most common LLC mistakes for non-residents is a smart move before you get too far into operations. Prevention is always cheaper than correction.
The bottom line from our perspective: the EIN process rewards preparation, not complexity. If you have your LLC formed and your Form SS-4 filled out correctly, the application is a straightforward task. The real work is what comes after, and having a reliable partner in your corner makes all the difference.
