ITIN for Wyoming LLC Non-Residents: Do You Need One

What is an ITIN?

An ITIN (Individual Taxpayer Identification Number) is a nine-digit tax processing number issued by the Internal Revenue Service (IRS) to individuals who are required to have a US taxpayer identification number but do not have and are not eligible to obtain a Social Security Number (SSN).

The IRS created the ITIN program in 1996 to allow foreign nationals and other individuals without SSNs to comply with US tax laws. An ITIN is formatted like an SSN (XXX-XX-XXXX) but always begins with the number 9. For example, 912-34-5678 would be an ITIN format.

An ITIN serves one purpose only: federal tax reporting. It does not authorize work in the United States, provide eligibility for Social Security benefits, or qualify a dependent for Earned Income Tax Credit purposes. The ITIN simply allows the IRS to process tax returns and payments from individuals who cannot obtain an SSN.

ITINs are issued regardless of immigration status because both resident and non-resident aliens may have US tax filing and payment responsibilities under the Internal Revenue Code. The IRS issues ITINs to individuals who need to file US tax returns or are listed on a US tax return as a spouse or dependent.

Do non-residents need an ITIN for a Wyoming LLC?

No. Non-residents do NOT need an ITIN to form a Wyoming LLC, obtain an EIN, open a US business bank account, or operate their business. An EIN (Employer Identification Number) is the only tax identification number required for the LLC itself.

Many non-residents confuse the ITIN with the EIN and believe they need both. This is incorrect. The ITIN and EIN serve completely different purposes. The EIN identifies the business entity for tax purposes. The ITIN identifies an individual for personal tax filing purposes.

For a single-member Wyoming LLC owned by a non-resident, the process is straightforward: file Articles of Organization with Wyoming, obtain an EIN from the IRS using Form SS-4, and open a business bank account using the EIN and LLC documents. No ITIN is involved at any step.

Mercury Bank, Relay Bank, Wise Business, and other banks that serve non-resident Wyoming LLC owners do not require or ask for an ITIN. They require the LLC's EIN, the Articles of Organization, the operating agreement, and the owner's passport. The EIN serves as the tax identification number for the business account.

Some formation services incorrectly suggest that non-residents need an ITIN before forming an LLC. This is a common misconception that leads to unnecessary expense and delay. Non-residents should not apply for an ITIN unless they have a specific personal US tax filing requirement. Learn more about the correct process in EIN for non-residents without SSN.

ITIN vs EIN: What's the difference?

The ITIN and EIN serve fundamentally different purposes, are issued to different entities, and are used in different contexts. Understanding the distinction prevents confusion and unnecessary applications.

ITIN (Individual Taxpayer Identification Number)

An ITIN is issued to individuals who need a US taxpayer identification number for personal tax purposes but cannot obtain an SSN. The ITIN is formatted as 9XX-XX-XXXX (always starts with 9). It is used for filing personal income tax returns, claiming treaty benefits, and reporting personal income.

The ITIN is obtained by submitting Form W-7 to the IRS along with proof of identity and foreign status documents. Processing takes 7-11 weeks. The ITIN must be renewed if not used on a tax return for three consecutive years.

EIN (Employer Identification Number)

An EIN is issued to business entities (LLCs, corporations, partnerships) to identify them for federal tax purposes. The EIN is formatted as XX-XXXXXXX. It is used for filing business tax returns, opening business bank accounts, hiring employees, and conducting business transactions.

The EIN is obtained by submitting Form SS-4 to the IRS. Non-residents submit by fax or mail since the online application requires an SSN. Processing takes 4-8 weeks by fax. The EIN never expires and remains with the business entity for its entire existence.

For non-residents forming a Wyoming LLC, only the EIN matters. The ITIN is irrelevant to LLC formation, banking, and most business operations. Non-residents should focus on obtaining the EIN and only consider an ITIN if they develop a specific personal US tax filing requirement.

When would a non-resident need an ITIN?

While non-residents do not need an ITIN to form or operate a Wyoming LLC, certain situations may create a personal US tax filing requirement that requires an ITIN. Understanding these scenarios helps non-residents determine if they should apply.

US Tax Filing Requirements

A non-resident might need an ITIN when filing a US personal income tax return. This occurs when the non-resident has US-sourced income that is not fully offset by treaty benefits or when they are claiming a refund of withheld taxes.

Examples include: receiving rental income from US real property, earning income from services performed in the US, receiving taxable US Social Security benefits, or claiming treaty benefits on Form 8833. In these cases, the non-resident files Form 1040-NR (US Nonresident Alien Income Tax Return) and needs an ITIN if they do not have an SSN.

Claiming Tax Treaty Benefits

Some tax treaties require the non-resident to file a US tax return to claim treaty benefits. The ITIN serves as the identification number on these returns. Without an ITIN, the IRS cannot process the return or apply the treaty benefits.

Receiving US-Sourced Passive Income

Non-residents receiving US-sourced dividends, interest, or royalties may have taxes withheld at source. To claim a refund of excess withholding or to report the income properly, the non-resident may need to file a US tax return using an ITIN.

Form 5472 as an Individual

In some complex ownership structures, a non-resident individual might need to file Form 5472 directly rather than through the LLC. This is rare for standard single-member LLCs but can occur in multi-tiered ownership arrangements. An ITIN would be required for this filing.

Selling US Real Property

Non-residents who sell US real property are subject to FIRPTA (Foreign Investment in Real Property Tax Act) withholding. To report the sale and claim any refund of excess withholding, the non-resident needs an ITIN to file Form 1040-NR.

Most non-residents with Wyoming LLCs never need an ITIN. The EIN handles all business-related tax identification needs. Non-residents should only apply for an ITIN if a specific personal US tax filing requirement arises.

How to apply for an ITIN?

If you determine that you need an ITIN, the application process involves submitting Form W-7 to the IRS along with documentation proving your identity and foreign status. The process takes 7-11 weeks, so apply well before any filing deadlines.

Step 1: Complete Form W-7

Download Form W-7 (Application for IRS Individual Taxpayer Identification Number) from the IRS website. Complete all required fields including: your full name, mailing address, birth information, foreign status, and the reason you are applying for an ITIN.

The form requires you to select a reason for applying. Most non-residents select either "a) Nonresident alien required to get ITIN to claim tax treaty benefit" or "h) Other" with an explanation of their specific tax filing requirement.

Step 2: Prepare Supporting Documents

You must submit original documents or certified copies from the issuing agency that prove both your identity and foreign status. The most common document is a passport, which proves both identity and foreign status in one document.

If you do not want to send your original passport, you can submit a certified copy from your passport issuing agency, use an IRS Acceptance Agent, or submit alternative documents such as a national identification card with photo and signature, or a combination of documents from the IRS list.

Step 3: Attach Federal Tax Return (if applicable)

Most ITIN applications must include a federal tax return (Form 1040-NR for non-residents). The ITIN is processed with the tax return. Exceptions apply for certain circumstances such as claiming treaty benefits or when an exception box is checked on Form W-7.

Step 4: Submit the Application

Submit Form W-7, supporting documents, and tax return (if required) using one of these methods:

• Mail: Send to IRS ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342
• Acceptance Agent: Work with a Certified Acceptance Agent who can verify documents and submit the application
• IRS Taxpayer Assistance Center: Schedule an appointment to submit documents in person

Step 5: Receive Your ITIN

The IRS processes ITIN applications in 7-11 weeks during peak season (January-April) and 6-8 weeks during other times. You will receive a letter assigning your ITIN. Original documents submitted by mail are returned to you separately within 60 days.

How long does ITIN application take?

ITIN applications typically take 7-11 weeks to process when submitted during peak filing season (January through April). Applications submitted outside of peak season generally process in 6-8 weeks. The IRS does not offer expedited processing for ITIN applications.

Processing Timeline

After submitting Form W-7 with supporting documents, the IRS reviews the application for completeness and accuracy. If documents are missing or unclear, the IRS may request additional information, extending the processing time. Once approved, the IRS mails a letter containing the assigned ITIN to the address on the application.

Peak vs Off-Peak Timing

The IRS receives the highest volume of ITIN applications during tax season. Applications submitted in January through April experience longer processing times. Applications submitted in May through December typically process faster, often within 6-8 weeks.

Checking Application Status

The IRS does not provide an online status check for ITIN applications. To check status, call the IRS ITIN hotline at 1-800-908-9982. Have your application information ready including the date submitted and any correspondence received. Allow at least 7 weeks from the submission date before calling.

Receiving Original Documents

If you submitted original documents by mail, the IRS returns them separately from the ITIN assignment letter. Documents typically arrive within 60 days of submission. If you do not receive your documents within 65 days, contact the IRS to request a status update.

Plan ahead when applying for an ITIN. If you need the ITIN for a specific tax filing deadline, apply at least 12 weeks in advance to ensure you receive the number in time. Remember that most non-residents with Wyoming LLCs do not need an ITIN at all, so consider whether you truly need one before beginning the application process.

Can I open a bank account with just an ITIN?

Generally no. US business bank accounts require an EIN (Employer Identification Number), not an ITIN. An ITIN is for individual tax filing purposes and does not substitute for the EIN required to open business accounts.

Business Bank Account Requirements

Banks that serve non-resident Wyoming LLC owners require the LLC's EIN to open a business account. The EIN identifies the business entity for tax reporting purposes. Mercury Bank, Relay Bank, Wise Business, and other non-resident-friendly banks specifically require:

• Approved Articles of Organization
• EIN confirmation letter (CP 575 or 147C)
• Operating agreement
• Passport of the LLC owner

An ITIN does not appear on this list because it is not relevant to business banking. The ITIN identifies an individual for personal tax purposes. The EIN identifies the business entity for all business purposes including banking, tax filings, and payment processing.

Personal Bank Accounts

Some US banks allow non-residents to open personal bank accounts with an ITIN. However, this is different from a business bank account for an LLC. Personal accounts opened with an ITIN cannot be used for business purposes and do not provide the business features needed for a Wyoming LLC such as merchant processing, business debit cards, or ACH transfers in the business name.

What You Actually Need

For a Wyoming LLC, focus on obtaining an EIN, not an ITIN. The EIN opens all necessary business banking and payment processing accounts. The process for non-residents involves submitting Form SS-4 by fax or mail, which typically takes 4-8 weeks. Once you have the EIN, you can open accounts with Mercury Bank, Relay Bank, Wise Business, and other non-resident-friendly institutions.

Non-residents should not waste time and money obtaining an ITIN for the purpose of opening a business bank account. The ITIN will not help. Instead, focus on getting the EIN for your Wyoming LLC.
