EIN for Wyoming LLC: Non-Resident Guide

Why Your Wyoming LLC Needs an EIN

An EIN (Employer Identification Number) is a 9-digit federal tax identification number the IRS assigns to your LLC. The EIN serves as the business equivalent of a Social Security Number. Every Wyoming LLC needs an EIN to conduct business, open bank accounts, process payments, and file tax returns.

Without an EIN, your Wyoming LLC cannot function as a real business. The EIN unlocks access to US banking infrastructure, payment processing systems, and compliance requirements. Non-resident LLC owners operate entirely through the EIN — the business itself has no physical presence in the US, so the EIN serves as its legal identity in the US financial and tax systems.

US Bank Accounts Require an EIN

Mercury, Relay, Chase Business Banking, and every other US business bank require an EIN before opening an account. Banks use the EIN to verify your business entity with IRS records, meet Bank Secrecy Act compliance requirements, and report interest income. You cannot open a US business bank account with just your LLC formation documents. The bank application form explicitly requests the EIN.

For non-resident LLC owners, fintech banks like Mercury and Relay are the most accessible banking options. Both accept non-resident founders and process applications entirely online. Both require an EIN as part of the application. Read the complete guide on opening a US bank account for your Wyoming LLC.

Stripe and PayPal Require an EIN

Stripe, PayPal Business, and other payment processors require an EIN to verify your US business entity. When you set up a Stripe account for your Wyoming LLC, Stripe asks for the business tax identification number during the verification process. That business tax ID is your EIN. Without an EIN, Stripe cannot verify your entity and will not activate your account.

The EIN allows payment processors to issue tax forms (Form 1099-K) and report payment processing volume to the IRS. Payment processors are legally required to report this information, so they cannot activate accounts for entities without valid EINs.

IRS Tax Filing Requires an EIN

Your Wyoming LLC must file Form 5472 and Form 1120 with the IRS each year if it is owned by a non-resident and has any reportable transactions. Form 5472 reports related-party transactions (transactions between the LLC and its owner). The form requires the LLC's EIN in multiple fields. You cannot file Form 5472 without an EIN.

The IRS uses the EIN to track all business filings, tax payments, and compliance. Once assigned, the EIN follows your LLC permanently. All future correspondence from the IRS references the EIN.

Hiring Employees or Contractors Requires an EIN

If your LLC hires employees, you must report payroll taxes using the LLC's EIN. If your LLC pays contractors $600 or more in a year, you must issue Form 1099-NEC using your EIN as the payer identification number. The EIN identifies your LLC on all employment and contractor tax documents.

Business Contracts May Require an EIN

Some US clients, suppliers, or partners request your EIN before entering into contracts. This is particularly common in industries with strict compliance requirements (finance, healthcare, government contracting). The EIN provides proof that your business is registered with the IRS and has a valid tax identification number.

Can Non-US Residents Get an EIN?

Yes. Non-US residents can obtain an EIN for their Wyoming LLC without a Social Security Number. The IRS explicitly allows international applicants to apply for EINs using alternative application methods. There is no citizenship, residency, or immigration requirement for EIN applications.

The restriction is procedural, not legal. The IRS online EIN application (Form SS-4 Online) requires an SSN or ITIN. Non-residents who have never worked in the US do not have these numbers and cannot use the online system. The IRS provides alternative application methods specifically for international applicants: fax and mail.

You Cannot Use the Online IRS Application

The IRS online EIN application is the fastest method (instant EIN issuance), but it requires the responsible party (the LLC owner or authorized signer) to have an SSN or ITIN. The online form validates SSN/ITIN format and will not accept passport numbers, foreign tax IDs, or blank entries.

This restriction exists because the online system performs real-time identity verification against Social Security Administration databases. Non-residents are not in those databases, so the system cannot verify their identity. The IRS solution is to use manual application methods with identity documentation.

You Must Apply Via Fax or Mail Using Form SS-4

Non-residents complete IRS Form SS-4 (Application for Employer Identification Number) and submit it by fax to the IRS international fax line at +1-267-941-1099 or by international mail to the IRS address in Cincinnati, Ohio. Both methods work equally well for non-residents. Fax is faster (2–4 weeks) compared to mail (4–6 weeks).

The paper Form SS-4 has a field for SSN/ITIN but allows you to write "Foreign" or "None" if you do not have one. The form includes fields for passport information and foreign address. The IRS processes these applications manually, which takes longer than the instant online system but results in the same EIN.

No ITIN Required for EIN Application

You do not need an ITIN to get an EIN. The two numbers are independent. The EIN is for the business entity (the LLC). The ITIN is for the individual (the owner). Many non-resident LLC owners obtain an EIN and operate for years without ever needing an ITIN. Learn more about the difference between EIN and Tax ID.

An ITIN becomes necessary only if you have a personal US tax filing obligation. Most non-resident LLC owners with online businesses have no US-source income and file only the LLC's Form 5472 (which uses the EIN, not an ITIN). The EIN comes first, and the ITIN comes later only if needed.

No US Address Required

You can apply for an EIN using your LLC's Wyoming registered agent address or your own foreign address. The IRS accepts both. If you use your registered agent's address, the EIN confirmation letter will be mailed there. Most registered agents forward mail to your international address. If you use your foreign address directly on Form SS-4, the IRS mails the EIN confirmation internationally.

How to Apply for EIN as a Non-Resident — Step by Step

The complete EIN application process for non-resident Wyoming LLC owners involves forming the LLC first, then completing Form SS-4, and submitting it by fax to the IRS international fax line. Here is the exact process from start to finish.

Step 1: Form Your Wyoming LLC First

You cannot apply for an EIN until your LLC exists as a legal entity. The IRS requires the date of LLC formation and the legal name exactly as it appears on the Wyoming formation documents. File your Articles of Organization with the Wyoming Secretary of State first. Wait for approval (typically 1-2 business days for online filings). Once you receive the approved Articles of Organization, you have the information needed for the EIN application.

Step 2: Download and Complete IRS Form SS-4

Download Form SS-4 from irs.gov. The form is a 2-page PDF. Complete all required fields using the information from your LLC formation documents. Use black ink or type the information. The form must be legible for manual processing by IRS staff.

Step 3: Fill In Required Information

The form requires the following key information:

• Line 1: Legal name of your Wyoming LLC exactly as it appears on the Articles of Organization
• Line 2: Trade name (if any) — most LLCs leave this blank
• Line 3: Name of responsible party (the LLC owner or authorized member)
• Line 4–6: Mailing address (can be your registered agent address or your foreign address)
• Line 7a/7b: Responsible party information including name and SSN/ITIN — write "Foreign" or "None" in the SSN field
• Line 8a: Check "Limited Liability Company" and write "Disregarded Entity" for single-member LLC
• Line 9a: Check "Started new business"
• Line 9b: Date you formed the LLC (date on your approved Articles of Organization)
• Line 10: Closing month of accounting year — most LLCs use December
• Line 11: Leave blank unless you expect to hire employees immediately
• Line 13: Date you need the EIN — write the current date

Sign and date the form. The signature certifies that the information is correct. The IRS may reject applications with missing signatures or dates.

Step 4: Submit by Fax to IRS International Fax Line

Fax the completed Form SS-4 to +1-267-941-1099 (IRS international fax line for EIN applications). Include a cover sheet with your name, LLC name, and return fax number or email. The fax transmission serves as proof of submission.

Alternatively, mail Form SS-4 to: Internal Revenue Service, Attn: EIN International Operation, Cincinnati, OH 45999, USA. Mail takes longer (4–6 weeks) but works for applicants without fax access. Use a tracked international shipping service for proof of delivery.

Step 5: Wait 2–4 Weeks for Processing

The IRS manually processes faxed applications. Processing time is typically 2–4 weeks, though it can extend to 6–8 weeks during busy periods (January–April tax season). The IRS does not send processing updates. You will receive the EIN confirmation letter by mail once processing is complete.

Step 6: Receive EIN Confirmation Letter (CP 575)

The IRS sends a confirmation letter (Form CP 575) to the mailing address listed on your Form SS-4. The letter contains your 9-digit EIN in the format XX-XXXXXXX. This letter is the official IRS record of your EIN assignment. Keep the original letter in your LLC records. Banks, payment processors, and tax preparers will request a copy.

Form SS-4 — What to Fill In

Form SS-4 has 18 lines, but non-resident single-member Wyoming LLC owners complete only 10-12 lines. This section explains each required field, common mistakes that cause delays, and exactly what to write.

Line 1: Legal Name of Entity

Enter the exact legal name of your Wyoming LLC as it appears on your approved Articles of Organization. Include "LLC" at the end. Examples: "Global Ventures LLC" or "Tech Innovations LLC". Do not abbreviate. Do not include any trade names or DBAs on this line.

Line 2: Trade Name of Business

If your LLC operates under a different trade name (DBA — Doing Business As), enter it here. Most LLCs leave this line blank. You only need a trade name if you use a different business name publicly. Example: Your LLC legal name is "Smith Holdings LLC" but you operate as "Smith Consulting" — enter "Smith Consulting" on Line 2.

Line 3: Executor, Administrator, Trustee, Care Of Name

Leave blank. This line is for estates and trusts, not LLCs.

Line 4–6: Mailing Address

Enter the address where you want the IRS to mail your EIN confirmation letter. You have two options:

• Registered agent address: Use your Wyoming registered agent's address. The registered agent will receive the letter and forward it to you. This is the most common option.
• Your foreign address: Use your personal or business address outside the US. The IRS will mail the letter internationally. This works but adds 1–2 weeks for international delivery.

Line 7a: Name of Responsible Party

Enter your name (the LLC owner or authorized member). The responsible party is the person who controls the LLC. For single-member LLCs, this is always the owner. Use your legal name as it appears on your passport.

Line 7b: SSN, ITIN, or EIN

This is the critical field for non-residents. If you do not have a US Social Security Number or ITIN, write "Foreign" or "None" or "N/A" in this field. Do not leave it blank (blank fields may cause processing delays). The IRS accepts these entries for international applicants.

Line 8a: Type of Entity

Check the box for "Limited Liability Company" and enter the tax classification on the line provided. For single-member LLCs owned by a non-US person, write "Disregarded Entity". For multi-member LLCs, write "Partnership". The tax classification determines which tax forms the LLC must file.

Line 9a: Reason for Applying

Check "Started new business". This is the correct reason for new LLC formations. Other options (hired employees, banking purposes, compliance with IRS withholding regulations) do not apply to new formations.

Line 9b: Date Business Started or Acquired

Enter the date your Wyoming LLC was approved by the Wyoming Secretary of State. This date appears on your approved Articles of Organization or your stamped filing receipt. Use MM/DD/YYYY format.

Line 10: Closing Month of Accounting Year

Enter the month your LLC's tax year ends. Most LLCs use the calendar year and enter "December". If you have a specific reason to use a fiscal year (rare for small businesses), enter the appropriate month. When in doubt, use December.

Line 11: Highest Number of Employees Expected

If you expect to hire employees in the next 12 months, enter the number. If not, leave blank or write "0". Most non-resident-owned online businesses have no employees and leave this blank.

Common Mistakes That Cause Delays

• Leaving Line 7b blank: Write "Foreign" if you have no SSN/ITIN.
• Wrong legal name: Must match Articles of Organization exactly, including "LLC".
• No signature or date: The form requires your signature and the date at the bottom.
• Illegible handwriting: Type the form or use clear block printing.
• Applying before LLC approval: Wait for the Wyoming Secretary of State to approve your Articles before applying for the EIN.

EIN Processing Time for Non-Residents

The IRS processes EIN applications from international applicants manually. Processing times vary by submission method and time of year. This section explains realistic timelines and what to do while waiting.

Fax Applications: 2–4 Weeks

Faxed Form SS-4 applications to the IRS international fax line (+1-267-941-1099) typically process within 2–4 weeks. The IRS receives the fax, manually reviews the application, assigns the EIN, and mails the confirmation letter (CP 575) to the address on your form. Total timeline from fax submission to receiving the letter by mail is 2–4 weeks.

During busy filing periods (January through mid-April), processing can extend to 4–6 weeks. The IRS prioritizes tax return processing during tax season, which delays EIN applications. If you submit during tax season, expect the longer timeline.

Mail Applications: 4–6 Weeks

Mailed Form SS-4 applications take longer because they include international delivery time to the IRS, manual processing time, and international return delivery time. Total timeline is typically 4–6 weeks but can extend to 8 weeks for applicants in countries with slow postal service.

Use tracked international shipping (FedEx, DHL, UPS) to ensure delivery. The IRS Cincinnati address receives thousands of documents daily. Untracked letters can be lost or significantly delayed. Tracking provides proof of delivery and estimated processing start date.

Online Application: Not Available for Non-Residents

The IRS online EIN application provides instant EIN issuance but requires the responsible party to have a valid SSN or ITIN. Non-residents without these numbers cannot use the online system. There is no workaround or exception. Learn more about what an EIN is and who needs one.

What to Do While Waiting for Your EIN

Use the 2–4 week EIN processing period productively:

• Prepare your operating agreement: Draft and sign your LLC operating agreement. Most registered agents provide a template.
• Gather banking documents: Collect your passport, proof of address, Articles of Organization, and operating agreement. Mercury and Relay require these documents for account opening.
• Research payment processors: Determine whether you'll use Stripe, PayPal, or another processor. Review their requirements for non-resident-owned businesses.
• Set up business systems: Create email addresses, purchase domains, set up your website, and configure business software.
• Plan your launch: Develop your marketing strategy, content plan, and sales process.

By the time you complete these tasks, your EIN will arrive and you can immediately open your bank account and activate Stripe.

What If Processing Takes Longer Than Expected?

If 6 weeks pass with no EIN confirmation letter, call the IRS Business and Specialty Tax Line at +1-267-941-1099 (international). Provide the LLC name, formation date, and responsible party name. The IRS can look up your application status and confirm whether the EIN was assigned. If the EIN was assigned but the letter was lost in the mail, the IRS can provide the EIN by phone and send a duplicate confirmation letter.

What You Receive

The IRS sends a confirmation letter when your EIN is assigned. This letter is the official proof of your EIN and one of the most important documents for your LLC. This section explains what the letter contains, how to use it, and what to do if you lose it.

CP 575 Confirmation Letter from IRS

The EIN confirmation letter is officially called Form CP 575 (Notice of Employer Identification Number Assigned). The letter is a single page printed on IRS letterhead. It contains the following information:

• Your 9-digit EIN: Displayed prominently in the format XX-XXXXXXX
• Legal name of your LLC: Exactly as you entered it on Form SS-4
• Business address: The mailing address from your Form SS-4
• Tax classification: Confirms whether the LLC is classified as a disregarded entity, partnership, or corporation
• Filing requirements: Brief summary of potential federal tax filing obligations
• Issue date: The date the IRS assigned the EIN

The EIN Itself (Format: XX-XXXXXXX)

The EIN is a 9-digit number formatted as XX-XXXXXXX (two digits, a hyphen, then seven digits). Example: 12-3456789. This is the number you will use on all business documents, bank applications, payment processor registrations, and tax filings. Always include the hyphen in the correct position.

The first two digits indicate the IRS office that issued the EIN. Numbers 20-59 indicate various IRS service centers. The remaining seven digits are sequential. There is no meaning encoded in the numbers beyond the IRS office location.

Keep This Document — Banks and Stripe Will Ask for It

The CP 575 letter is proof that the IRS assigned an EIN to your LLC. Banks require a copy during the business account application. Stripe and PayPal request it during verification. Some tax preparers request it when setting up your account. Government agencies request it when issuing licenses or permits.

Keep the original letter in your LLC records binder or digital records folder. Make multiple copies or scans. Upload a PDF to secure cloud storage. Replacing a lost EIN letter is possible but time-consuming (requires calling the IRS and waiting for a duplicate to be mailed).

What If the Letter Contains Errors?

If the CP 575 letter shows the wrong legal name, wrong address, or wrong tax classification, you must correct it immediately. Call the IRS Business and Specialty Tax Line at +1-267-941-1099 (international) to request a correction. The IRS will ask you to fax or mail documentation (Articles of Organization, corrected Form SS-4) to support the correction. Processing takes 4–6 weeks. Do not use an EIN with incorrect information — it will cause complications later.

What Comes Next After You Have Your EIN

Receiving your EIN is a major milestone in your Wyoming LLC setup. The EIN unlocks access to US banking, payment processing, and full business operations. This section explains the immediate next steps and typical timeline.

Open a US Business Bank Account

The first and most important next step is opening a US business bank account. Mercury and Relay are the top two fintech banks for non-resident-owned Wyoming LLCs. Both accept international founders, process applications entirely online, and do not require you to visit a US branch.

To apply, you need:

• Your EIN (the CP 575 confirmation letter)
• Articles of Organization (approved by Wyoming Secretary of State)
• Operating agreement (signed)
• Your passport (valid, government-issued)
• Proof of address (utility bill, bank statement, government document showing your residential address)

Mercury and Relay review applications within 1–3 business days. Approval rates are high for legitimate businesses with complete documentation. Once approved, you receive a US bank account number and routing number, a debit card mailed internationally, and access to ACH transfers, wire transfers, and check deposits. Read the complete guide on opening a US bank account for your Wyoming LLC.

Set Up Stripe for Payment Processing

Stripe is the most popular payment processor for online businesses. To set up Stripe, you need your EIN, business bank account information, and personal identification (passport). Stripe's onboarding process requests business details, the business tax ID (your EIN), bank account for payouts, and representative information.

Stripe performs identity verification and business verification. For non-resident-owned LLCs, this verification includes checking the EIN against IRS records and verifying the representative's identity using passport information. Verification typically completes within 1–2 business days. Once verified, you can start accepting payments.

File Your Annual Compliance

Your Wyoming LLC has two annual compliance requirements:

• Wyoming Annual Report: Filed with the Wyoming Secretary of State. Due by the first day of the anniversary month of your LLC formation. Fee: $60 online or $62 by mail. This keeps your LLC in good standing with Wyoming.
• Federal tax filing: File Form 5472 and pro forma Form 1120 with the IRS. Due by the 15th day of the 4th month after your tax year ends (April 15 for calendar year LLCs). This reports related-party transactions and maintains IRS compliance. Uses your EIN.

With your EIN, bank account, and payment processing in place, your Wyoming LLC is fully operational. You can invoice clients, accept online payments, pay contractors, deduct business expenses, and operate as a legitimate US business entity from anywhere in the world.
