How to Get an EIN for an LLC (Especially a Wyoming LLC as a Non‑US Founder)

• An EIN is a free unique nine digit number issued by the Internal Revenue Service that your LLC needs for taxes, banking, and connecting payment processors like Stripe and PayPal.

• Both single member LLC and multi-member LLCs typically need an EIN, even if they have no employees yet—it’s essential for separating personal and business finances.

• Non-US owners without a social security number can still get an EIN by mailing or faxing Form SS-4 to the IRS, or by using a service like FormYourCorp that specializes in foreign founder applications.

• Timeline varies by method: IRS online or phone (for SSN/ITIN holders) delivers the EIN immediately, fax takes about 4–7 business days, and mail takes 4–6 weeks; FormYourCorp handles submissions through optimized channels for faster processing.

• Your EIN is permanent for the life of your LLC and becomes the foundation for all federal tax filings, US business bank account applications, and official documentation.

An Employer Identification Number (EIN), also called a federal tax identification number or federal tax id number, is a unique nine-digit identifier assigned by the Internal Revenue Service IRS to identify your LLC for tax purposes and reporting obligations. Think of it as your LLC’s version of a social security number—but exclusively for business entities, not individuals.

When you form a Wyoming LLC, the state handles your formation documents, but the EIN always comes from the IRS at the federal level. This means your Wyoming LLC’s EIN is completely separate from any state-level business registration numbers or licenses. The IRS uses this taxpayer identification number to track your company’s tax obligations, employment taxes, and other federal reporting requirements.

It’s worth briefly distinguishing the EIN from other tax identification numbers you might encounter. Your personal social security number (SSN) identifies you as an individual taxpayer. An individual taxpayer identification number (ITIN), sometimes called taxpayer identification number itin, serves non-residents who need to file taxes but aren’t eligible for an SSN. A preparer tax identification number (PTIN) is used by tax preparers who help others with preparing federal tax returns. The EIN stands apart as the id number specifically designed for business entities like your LLC.

FormYourCorp obtains EINs for every Wyoming LLC we form, including for international applicants and non-residents without an SSN. Our process handles the IRS paperwork so you can focus on launching your business.

Most Wyoming LLCs should get an EIN from day one, even single member LLCs with no employees. The practical reality is that you’ll need this tax id number to open a business bank account, connect payment processors, and keep your personal finances separate from your business finances.

Here’s when an EIN is specifically required:

• Multi-member LLCs with two or more owners must have an EIN for partnership tax filings (Form 1065)

• Any LLC with employees must have an EIN for payroll taxes, employment taxes, and to withhold taxes from wages

• LLCs electing S-corp or C-corp taxation must obtain an EIN regardless of member count

• LLCs opening US bank accounts at institutions like Mercury, Relay, or traditional banks need an EIN for verification

• LLCs using Stripe, PayPal, or Amazon require an EIN to complete merchant account setup

• LLCs receiving 1099 payments from US clients need an EIN to avoid exposing your personal SSN

A single member Wyoming LLC classified as a “disregarded entity” could technically file business and personal taxes using the owner’s SSN. However, using an EIN provides significant advantages for privacy and asset protection. When you give vendors and clients an EIN instead of your personal SSN, you reduce your exposure to identity theft and maintain clearer separation between personal assets and business obligations.

For non-US founders, the EIN becomes even more critical. Without a US SSN, you cannot access most American banking and payment infrastructure. Your Wyoming LLC’s EIN serves as the primary identifier that unlocks these systems, allowing you to receive payments, pay taxes, and operate your business remotely from anywhere in the world.

Our recommendation: Every Wyoming LLC formed through FormYourCorp should obtain an EIN from the start. It’s free from the IRS, and the benefits far outweigh any minor hassle of the application process.

The ein application process is free through the IRS and can be completed online, by phone, by fax, or by mail. The method you’ll use depends primarily on whether the responsible party has an SSN or ITIN—if not, you’ll need to use phone, fax, or mail channels.

This section walks through the standard IRS process step by step. For Wyoming LLC owners who prefer a hands-off approach, FormYourCorp handles all of these steps as part of our formation packages.

Here’s the high-level process:

1. Confirm you actually need an EIN (most Wyoming LLCs do)

2. Choose the responsible party who will be listed on the application

3. Gather all required information about your LLC

4. Complete IRS Form SS-4 accurately

5. Submit via the appropriate channel based on your situation

6. Receive and safely store your EIN confirmation notice

Each step is detailed below with concrete instructions tailored specifically to Wyoming LLCs and non-US owners.

Step 1: Choose the Responsible Party for Your LLC

The IRS defines the responsible party as the individual who ultimately owns or controls the LLC and is responsible for managing its funds and assets. This person’s name and taxpayer id number will appear on Form SS-4 and in IRS records.

For a single member Wyoming LLC, the responsible party is typically the sole owner. For a multi-member LLC, it’s usually the managing member designated in your Operating Agreement. The key requirement is that this must be a real person—the IRS generally does not accept another business entity as the responsible party for an LLC’s initial ein application.

The responsible party must provide their taxpayer identification number on the form. This can be:

• A social security number (SSN) for US citizens and residents

• An individual taxpayer identification number (ITIN) for resident aliens or certain non resident alien individuals

• “Foreign” notation if the responsible party has no US tax ID

FormYourCorp guides every founder through selecting the correct responsible party during our onboarding flow. We ensure this critical decision is made correctly before any IRS paperwork is submitted.

Step 2: Gather the Information You’ll Need

Before starting your ein application, collect all the business details you’ll need to complete Form SS-4. Inaccuracies here are the leading cause of delays and rejections, so double-check everything against your Wyoming formation documents.

Information checklist:

The legal name must match your Wyoming filing exactly—every comma, period, and “LLC” designation matters. Mismatched names are one of the most common reasons the IRS rejects applications or sends back clarification requests.

FormYourCorp pre-fills most of these fields automatically for our clients using data from your Wyoming formation. This significantly reduces errors and speeds up the approval process.

Step 3: Complete IRS Form SS‑4 for an LLC

All EIN applications, regardless of how you submit them, are based on IRS Form SS-4. Whether you apply online, by phone, or via paper form, you’ll be answering the same questions derived from this document.

Here’s how to complete the key lines for a Wyoming LLC:

Line 1: Enter the LLC’s legal name exactly as it appears on your Wyoming Articles of Organization. Don’t abbreviate “Limited Liability Company” if you filed it as “LLC” or vice versa.

Lines 4-6: Enter your mailing address and physical address. Many Wyoming LLCs use a registered agent mailing address here for privacy—this is perfectly acceptable and keeps your personal address out of IRS records.

Line 8a/8b: Indicate “LLC” as the entity type and specify the number of members. Note whether the LLC is a disregarded entity (single-member) or if you’re electing corporate tax treatment.

Line 9a: Check “Limited liability company (LLC)” and specify your tax classification. Most single member LLCs are disregarded entities taxed as sole proprietorship, while multi-member LLCs default to partnership taxation.

Line 10: State your reason for applying. Common responses include “Started a new business” or “Banking purposes.”

Lines 11-18: Provide information about expected first wages (if you plan to hire employees), your principal business activity description, and your accounting year. Write “N/A” for sections that don’t apply.

For international applicants without an SSN/ITIN: On the responsible party TIN line, write “Foreign” or leave it blank per IRS guidance. Ensure any foreign address is formatted correctly with country name spelled out.

For fax and mail submissions, ensure handwriting is clear and legible. Use the US date format (MM/DD/YYYY) consistently throughout the completed form.

FormYourCorp uses templates specifically designed for Wyoming LLC EIN applications, eliminating common SS-4 mistakes that cause weeks of delays for foreign founders.

Step 4: Submit Your EIN Application (Online, Phone, Fax, or Mail)

Your submission method depends on whether the responsible party has an SSN or ITIN and their physical location. Here’s how each channel works:

Online Application (SSN/ITIN holders only)

The IRS website offers an online EIN Assistant at irs.gov that lets you apply online and receive your ein immediately. Key details:

• Available Monday through Friday, 7:00 AM to 10:00 PM Eastern Time

• Responsible party must have a valid SSN or ITIN

• LLC must have a US address on file

• Session times out after 15 minutes with no ability to save progress

• Upon approval, you can download or print your confirmation letter instantly

Phone Application (International Applicants)

International applicants can call the IRS directly at +1-267-941-1099 during US business hours (6:00 AM to 11:00 PM Eastern Time, Monday through Friday). The agent will walk through the SS-4 questions verbally and assign your EIN during the call. Be prepared for potentially long hold times, especially during peak tax season.

Fax Submission

Faxing a completed Form SS-4 is a common method for non-US founders working through a service. Submit to the appropriate IRS fax number (currently 855-641-6935 for foreign applicants). Expect your EIN within approximately 4-7 business days. The IRS will fax back your confirmation.

Mail Submission

Mail your completed SS-4 to the IRS at the address specified for foreign applicants (currently: Internal Revenue Service, Attn: EIN International Operation, Cincinnati, OH 45999). This method takes 4-6 weeks and is the slowest option but requires no phone calls or fax machines.

How FormYourCorp handles this: For our Wyoming LLC clients, we determine the correct submission channel based on your situation, prepare all documentation, submit on your behalf, monitor status, and upload your EIN confirmation notice directly to your client dashboard once received.

Step 5: Receive, Store, and Use Your EIN

Once approved, the IRS issues a CP 575 confirmation letter (or equivalent notice) showing your new EIN and LLC details. This document is critical—banks and payment processors often request it as proof of your tax identification number.

Storage recommendations:

• Keep the original physical copy in a secure location

• Scan and save a digital copy to cloud storage

• Add it to your LLC’s important documents folder

• If you’re a FormYourCorp client, we upload it to your digital dashboard

First steps after receiving your EIN:

1. Open a US business bank account using your EIN, LLC documents, and Wyoming formation certificates. Popular options for non-US founders include Mercury, Relay, and Wise Business.

2. Connect payment processors like Stripe, PayPal, or Shopify Payments using your EIN for merchant verification.

3. Register for payroll accounts if you plan to hire employees and need to manage employment taxes and managing payroll obligations.

4. Update your records to use the EIN on all contracts, invoices, and official business correspondence.

Your EIN becomes effective immediately upon issuance. From this point forward, use it on all federal tax return filings, W-9 forms, and anywhere your LLC’s tax identification number is requested.

FormYourCorp helps clients use their new EIN to complete US banking setups with guidance integrated directly into our dashboard. We’ve established relationships with founder-friendly banks that understand the needs of non-US LLC owners.

An EIN is generally permanent for the life of your LLC. However, certain structural changes may require obtaining a new EIN or updating your information with the IRS.

This section covers when you need a new ein, when you only need to update IRS records, and what happens when you close your Wyoming LLC.

One important note: Wyoming’s “anonymous LLC” features—which provide privacy around member information at the state level—do not change federal EIN rules. Your LLC’s ownership structure must still be accurately reported to the IRS, even if it’s shielded from public state filings.

FormYourCorp can advise Wyoming clients when structural changes may trigger EIN or IRS updates, though final decisions should always follow current IRS guidance.

When You Need a New EIN for Your LLC

Certain changes fundamentally alter your LLC’s identity in the eyes of the IRS and require obtaining a new EIN:

• Converting your single member llc to a corporation (C-corp or S-corp) in a way the IRS treats as creating a new entity

• Changing from single-member to multi-member (or vice versa) when the change affects your LLC’s tax classification

• Complete ownership transfer where a new owner takes over all assets and operations with a change in entity structure

• Business acquisition where you purchase an existing ein and its associated business structure

Simple ownership percentage changes or adding a member without changing the underlying tax classification typically do not require a new EIN. However, the rules here can be nuanced.

Before assuming you can keep or must change your existing ein, consult current IRS EIN guidance or speak with a qualified tax professional. If a new EIN is required, the application process follows the same steps outlined earlier—just with updated information reflecting your new structure.

Updating Address, Name, or Ownership Without a New EIN

Many routine changes only require updating IRS records, not obtaining a completely new EIN:

• Address changes: Moving your Wyoming LLC’s mailing address or principal place of business

• Responsible party updates: Changing who controls the LLC when management changes hands

• Legal name changes: Updating your LLC’s name after filing an amendment with Wyoming Secretary of State

These updates are typically made via written notice to the IRS. Form 8822-B is the standard form for changing your business address or updating the responsible party information. For name changes, a signed letter to the IRS explaining the change usually suffices.

Keep IRS records current to avoid lost correspondence, compliance notices, or banking complications. When government entities or financial institutions verify your EIN, discrepancies between their records and IRS data can create unnecessary friction.

FormYourCorp clients can request guidance on which IRS form or letter format to use when changing addresses, responsible party, or other details.

Closing a Wyoming LLC and What Happens to the EIN

An EIN is never truly “canceled”—it remains in IRS records indefinitely. However, it becomes inactive when your LLC is formally closed and all final tax returns are filed.

To properly close a Wyoming LLC:

1. Dissolve the LLC with the Wyoming Secretary of State following state dissolution procedures

2. File taxes for the final year of business activity on all required federal income tax return forms

3. Mark all final returns as “Final Return” to signal the business has ceased operations

4. Pay any remaining business taxes owed

After filing final returns, the EIN stays in IRS records but is no longer used for new filings. The IRS associates it permanently with your now-closed LLC.

Important: Do not reuse an existing ein for a new, unrelated business entity. Even if you’re starting a new Wyoming LLC in the same industry, each separate business needs its own ein.

FormYourCorp can support Wyoming LLC owners with state dissolution filings and guidance on the federal steps required around closing your EIN and meeting final tax obligations.

Many FormYourCorp customers are non-US residents unfamiliar with the American tax ID landscape. Understanding the differences between various taxpayer identification number types helps clarify what you need—and don’t need—to launch your Wyoming LLC.

The main TIN types relevant to foreign founders:

The key point: You do not need an SSN to get an EIN for your Wyoming LLC. The IRS will issue an EIN to foreign-owned LLCs using Form SS-4 submitted via mail, fax, or international phone—even when the responsible party has no US tax identification number.

In some cases, a non-US LLC member may later need an ITIN for personal tax filing. This might occur if:

• You need to file taxes to claim tax treaty benefits

• Your LLC has US-source income requiring a federal tax return

• You’re claiming treaty benefits under an applicable tax treaty

Obtaining an ITIN is a separate process from your LLC’s EIN and involves the Social Security Administration for verification and IRS Form W-7 submission. FormYourCorp focuses on obtaining the EIN for your company and can refer clients to vetted tax professionals for personal ITIN questions and tax treaty considerations.

Common EIN Challenges for Foreign‑Owned Wyoming LLCs

Foreign founders face specific obstacles when applying for an EIN:

IRS online rejection: The IRS website’s online EIN system requires a valid SSN or ITIN. Without one, you cannot apply online, which eliminates the fastest and most convenient method.

Form SS-4 confusion: Lines requesting the responsible party’s TIN, address formatting for foreign locations, and business description codes create uncertainty. Incorrectly completed forms get sent back for clarification, adding weeks to the timeline.

Phone line challenges: The IRS international phone number operates on US Eastern Time hours, creating difficulties for founders in Asia, Australia, or Europe. Long hold times and language barriers compound the frustration.

Mail delays: Forms mailed from overseas can take weeks to reach the IRS, and return mail with your EIN confirmation faces similar delays.

FormYourCorp mitigates these issues by:

• Using properly completed SS-4 templates specifically designed for foreign founders

• Submitting through the channels best suited for non-US owners based on current IRS processing speeds

• Tracking all IRS correspondence and providing status updates via your online dashboard

• Handling any clarification requests without requiring your direct involvement

This support is especially valuable for digital nomads, e-commerce sellers, and agency owners who need fast Stripe and PayPal access to start generating revenue. When weeks of delay mean lost income, having an experienced team handle the IRS bureaucracy pays for itself quickly.

Obtaining your EIN is just the first step. The real value comes from using it to unlock US financial infrastructure and maintain proper compliance over time.

Your Wyoming LLC’s EIN is typically required by:

• US business banks (online and traditional) for opening checking and savings accounts

• Payment processors like Stripe, PayPal, Amazon, and Shopify for merchant account verification

• Clients and platforms issuing 1099-NEC or 1099-MISC forms for payments made to your LLC

• Government entities for business licenses, permits, and any excise tax return filings

Using your EIN instead of your personal SSN helps preserve privacy and maintain the “corporate veil” for asset protection. When your LLC operates as a genuinely separate entity with its own tax id number, bank account, and records, courts are more likely to respect that separation if legal issues arise.

Ongoing responsibilities with your EIN:

FormYourCorp offers reminders and support for Wyoming annual compliance and BOI reporting. Our dashboard keeps all your obligations visible so nothing falls through the cracks as you grow.

The following questions address common concerns not fully covered above, especially for foreign founders and privacy-focused owners forming Wyoming LLCs.

Can I run my Wyoming LLC without an EIN?

Technically, a single member llc with a US owner could use the owner’s SSN for tax filing purposes. However, in practice, you’ll need an EIN to open a US bank account, connect Stripe or PayPal, and maintain proper separation between business and personal finances.

Multi-member LLCs, LLCs with employees, and LLCs electing corporate tax treatment must have an EIN—there’s no workaround. For most Wyoming LLCs, especially those formed by non-US owners or independent contractor service providers, operating without an EIN is impractical and not recommended.

How long does it take to get an EIN for a foreign‑owned Wyoming LLC?

Timeline depends entirely on your submission method. Phone applications for international businesses can result in receiving the EIN immediately during the call. Fax submissions average around 4-7 business days. Mailed SS-4 forms may take 4-6 weeks or longer, especially when mailed from overseas.

IRS backlogs during peak tax season (January through April) can extend these timelines. FormYourCorp’s process uses the fastest available methods for non-US founders, and our clients typically receive their EINs within standard IRS processing windows.

If the EIN is free, why use FormYourCorp instead of doing it myself?

The Internal Revenue Service doesn’t charge for issuing an EIN, but the process can be confusing—especially for foreign founders without SSNs navigating Form SS-4 for the first time. Errors on the application cause weeks of delays when forms get rejected or sent back for clarification.

FormYourCorp’s value lies in correctly preparing SS-4 forms using proven templates, selecting the optimal submission method, handling all IRS communication, and bundling the EIN into a complete Wyoming LLC formation and banking setup. This lets you focus on launching your business rather than battling US bureaucracy. Our clients avoid the 80% of application delays caused by preventable preparation errors.

What if I lose my EIN confirmation letter?

Your EIN doesn’t disappear if you lose the paperwork—it remains permanently in IRS records. You can often find your EIN on past tax returns, bank account opening documents, or your FormYourCorp dashboard (if we formed your company).

If all records are lost, US-based owners can call the IRS Business & Specialty Tax Line to verify their EIN after completing identity verification. We strongly advise keeping scanned copies of your EIN letter in multiple secure locations. FormYourCorp stores the EIN notice digitally for all Wyoming LLC customers in their client dashboard.

Can I use one EIN for multiple LLCs?

No. Each separate LLC needs its own ein—you cannot legally share one EIN across multiple Wyoming entities or across different states. The IRS considers each LLC a distinct taxpayer with its own tax identification number.

Using one EIN for multiple businesses creates severe tax filing complications, banking problems, and liability exposure. It also violates IRS rules and can trigger audits or penalties.

If you form additional Wyoming LLCs through FormYourCorp, we obtain distinct EINs for each entity as part of the formation process. Each company operates independently with its own tax laws compliance and own ein.

Getting your EIN is the gateway to US banking, payment processing, and building a legitimate global business through your Wyoming LLC. The process is straightforward when you understand the steps—or when you have an experienced team handling it for you.
