W-8BEN, W-8BEN-E, or W-9: Which One a Foreign LLC Owner Needs

Short answer: If you are an individual who lives outside the United States and you are the sole owner of a U.S. LLC treated as a disregarded entity, the appropriate form is usually W-8BEN, completed with your information as the owner. W-8BEN-E is for foreign entities, and W-9 is for U.S. persons. Having an EIN does not make you a U.S. person. Even so, there are exceptions, and the correct form depends on who the beneficial owner of the income is, how the LLC is taxed, and the type of income.

When a platform, client, or financial institution asks you for "tax documentation," it is not asking you to choose the form that sounds most like your business. It is asking you to certify who actually receives the income for U.S. tax purposes. In this guide, we explain how to think it through before signing.

The decision in 60 seconds

These are the most common cases. They are general guidelines: each one should be confirmed with the official IRS instructions and, if you have questions, with a tax professional.

• You are a foreign individual and receive payments in your own name: usually W-8BEN.
• You are a foreign individual and the sole owner of a U.S. LLC with no corporate election (disregarded entity): usually W-8BEN with your information as the owner, because the IRS considers you the beneficial owner of the income received by the LLC.
• Your LLC elected to be taxed as a corporation (Form 8832 or 2553): the LLC becomes a U.S. domestic corporation, meaning a U.S. person. In that case, a W-9 signed by the LLC using its EIN is usually appropriate.
• Your LLC has multiple members and is taxed as a partnership: the LLC is a U.S. domestic partnership and usually provides a W-9 in the LLC’s name.
• The recipient is a company formed outside the U.S. (for example, an S.A.S. or an S.L.): usually W-8BEN-E.
• The income is effectively connected with a U.S. trade or business (ECI): W-8ECI may be appropriate instead of W-8BEN.
• You act as an intermediary or as a foreign flow-through entity: W-8IMY may be appropriate.

What W-8BEN is

Form W-8BEN is provided by a foreign individual who is the beneficial owner of income. It documents that the person is not a U.S. person and, when applicable, allows them to claim benefits under a tax treaty between their country of residence and the United States.

There are three key points:

• It is provided to the payer or withholding agent, such as the platform or client requesting it. It is not sent to the IRS.
• It must be provided when requested, whether or not you claim a reduced withholding rate.
• It has a limited validity period. According to the IRS instructions, it is generally valid from the date it is signed through the last day of the third following calendar year, unless a change in circumstances makes any information incorrect. For example, a form signed in September 2026 usually expires on December 31, 2029.

The form asks for your foreign tax identification number and, in some cases, a U.S. tax number such as an ITIN. If you want to understand what an ITIN is and when it is required, we have a practical ITIN guide.

What W-8BEN-E is

W-8BEN-E is the version for foreign entities: companies, foundations, or other entities formed outside the United States that are the beneficial owners of income or that must document their FATCA status with a financial institution.

A common mistake is to think: "My business is an entity and its owner is foreign, so I use W-8BEN-E." An LLC formed in Wyoming, Delaware, or any other state is a U.S. entity, not a foreign entity. That is why W-8BEN-E should not be recommended automatically just because its owner lives in Colombia, Mexico, or Spain.

The IRS instructions themselves provide for exceptions in which a disregarded entity uses W-8BEN-E, such as when it is a hybrid entity claiming treaty benefits as a resident for treaty purposes, or when it is only documenting its chapter 4 status with a foreign financial institution. These are specific situations that should be reviewed with a professional.

What W-9 is

Form W-9 is used by U.S. citizens and other U.S. persons (including tax residents, domestic partnerships, and domestic corporations) to provide their taxpayer identification number (TIN) to the requester.

When you sign a W-9, you certify under penalty of perjury that you are a U.S. person. Therefore, a foreign owner should not sign it as if they were a U.S. person just because their LLC has an EIN. The EIN identifies the business to the IRS; it does not change the residence or tax status of its owner. If you want to learn more, we explain what an EIN is and what it is used for.

EIN, ITIN, and foreign tax number: three different functions

• EIN: the business’s identification number with the IRS. The LLC needs it for procedures such as opening accounts or filing information returns.
• ITIN: an individual taxpayer identification number for people who cannot obtain an SSN and have a U.S. tax obligation or purpose. It is not always required.
• Foreign tax number: the identifier from your country of residence (for example, RFC, NIT, or NIF), which W-8BEN usually requests.

Having one does not replace the others, and none of them alone determines which W-8 or W-9 form is appropriate.

Practical case: owner of a Wyoming LLC receiving payments through a platform

Imagine Andrés, who lives in Medellín. He has a single-member Wyoming LLC with an EIN and has not made any election to be taxed as a corporation. He opens an account with a U.S. payment platform in his LLC’s name, and the platform asks him to "complete his tax information."

The account says "Andrés Studio LLC," so his first reaction is to choose W-9 (because the LLC is a U.S. entity) or W-8BEN-E (because it is an entity). Neither choice should be made based on the name shown on the account. Here is what should be reviewed:

1. The LLC’s tax classification. Because no corporate election was made and it has a single member, the LLC is a disregarded entity: for federal income tax purposes, the IRS disregards it and looks to its owner.
2. Beneficial owner. According to the W-8BEN instructions, if you are the sole owner of a disregarded entity, you are considered the beneficial owner of the income received by the entity. Here, the beneficial owner is Andrés, a foreign individual.
3. Resulting form. In general, Andrés would complete a W-8BEN with his name, country of residence, and Colombian tax number. The form’s reference line may be used for information helpful to the payer, such as the LLC’s name or account number, if the payer requests it that way.
4. Type of income. If the income were effectively connected with a U.S. trade or business, W-8ECI might be the appropriate form. This is a technical determination that should not be made based on intuition.
5. Payer requirements. Each platform or payer has its own collection process. Review its current instructions and, if the interface does not offer the appropriate option, ask its support team before signing.

The same reasoning applies if Andrés lived in Mexico or Spain: what changes is his country of residence, the tax treaty that might apply, and his obligations in his own country—not the logic for choosing the form.

Common mistakes and their consequences

• Signing a W-9 as a foreign person. This means certifying a U.S. status that you do not have. It may lead to incorrect reporting to the IRS and later issues with the payer.
• Choosing W-8BEN-E for a single-member U.S. LLC. Except for the hybrid entity or FATCA documentation exceptions, it is usually the wrong form.
• Not providing any form. If you do not provide valid documentation when requested, the payer may apply the 30% withholding rate for foreign persons or backup withholding, depending on the type of payment. The specific rate depends on the case.
• Forgetting the expiration date. An expired W-8BEN may be treated as if no documentation had been provided.
• Not updating it after a change. A change in residence or tax classification may invalidate the form.
• Assuming an ITIN is always required. An ITIN is only necessary in certain cases, such as some treaty benefit claims. It is not an automatic requirement for every W-8BEN.

When the answer changes

• Corporate election: if the LLC elected to be taxed as a corporation, it is a domestic corporation and usually provides a W-9 using its EIN.
• Multiple members: a U.S. LLC with multiple members that is taxed as a partnership is a domestic partnership and usually provides its own W-9.
• The owner is a foreign entity: if the LLC’s sole member is, for example, a Colombian S.A.S., the beneficial owner is that entity, and a W-8BEN-E in its name is usually appropriate.
• ECI income: if the income is effectively connected with a U.S. trade or business, W-8ECI may be appropriate.
• Foreign intermediary or flow-through: W-8IMY may be appropriate.
• Change in residence or status: if you become a U.S. tax resident or change your country of residence, you must notify the payer and provide a new form within the period established by the rules.

Steps before signing

1. Identify the beneficial owner: who receives the income for tax purposes—you as an individual, your LLC, or another entity?
2. Confirm the LLC’s tax classification: disregarded entity, partnership, or corporation.
3. Define the type of income: services, royalties, interest, sales, or income connected with a U.S. activity.
4. Review who is requesting it and why: payer, platform, or financial institution, along with its current instructions.
5. Determine the applicable TIN: foreign tax number, ITIN, or EIN, depending on the form.
6. Note the expiration date and any change in circumstances that would require you to update it.

Keeping your LLC in good standing also helps: if your business has transactions with its foreign owner, also review whether it must file Form 5472.
