W-8BEN vs W-8BEN-E for Foreign-Owned US LLCs: Which Form Do You Actually Send?

Your US Client Just Asked for a W-9. Stop. You Probably Shouldn't Send One.

If you own a US LLC as a non-resident and an American client emails you a Form W-9 to fill out before they pay your invoice, your instinct is to fill it in and move on. Don't. In almost every case, a foreign-owned single-member LLC should not be giving a W-9 at all. The correct document is a W-8 form, and signing the wrong one can create real tax-withholding and compliance problems for both you and your client.

This is one of the most common questions we get from non-resident LLC owners, so here is the clear, IRS-grounded answer.

Why Your LLC Is "Invisible" to the IRS

By default, a single-member LLC owned by a non-US person is treated as a "disregarded entity" for US federal income tax purposes. The IRS looks straight through the LLC to its owner. For payment and withholding purposes, the beneficial owner of any income the LLC receives is you, the foreign owner — not the LLC itself.

This is the rule that drives everything below. The party who must certify their tax status to your US client is the foreign owner, not the US-formed LLC.

What the W-9 Is For (And Why It Doesn't Fit You)

Form W-9 is the IRS form used by US persons — US citizens, US residents, and US-formed entities owned by US persons — to certify their taxpayer identification number so a payer can issue a Form 1099 at year-end.

The instructions to Form W-9 are blunt on this point: if you are a foreign person, do not use Form W-9. Instead, you must use the appropriate Form W-8 or Form 8233. Signing a W-9 with your LLC's EIN as if you were a US person can misrepresent your tax status, push your client into the wrong withholding regime, and create a paper trail that contradicts your actual non-resident filings.

The Right Form Depends on Who Owns the LLC

Because the foreign owner is the beneficial owner of the income, the form you provide is the form for that owner — not for the LLC.

If the LLC is owned by a foreign individual (you personally), you provide Form W-8BEN — "Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals)."

If the LLC is owned by a foreign company (for example, a UK LTD, a UAE FZE, or any non-US corporation that holds your LLC), the owning entity provides Form W-8BEN-E — the entity version of the same certificate.

In both cases, the form names you (or your foreign company) as the beneficial owner. The disregarded LLC is normally listed only as the entity receiving the payment, not as the beneficial owner.

What You Actually Write on the Form

A few practical points that trip people up:

On Form W-8BEN (individual), the name on Line 1 is your personal legal name, the country of citizenship is your country, the permanent residence address is your home address abroad (not a US mail-forwarding address), and the taxpayer identification number line is for your foreign tax ID, or an ITIN if you have one — not your LLC's EIN.

On Form W-8BEN-E (entity), Line 1 is the foreign entity's legal name, Line 2 is its country of incorporation, and Line 3 is where you put the disregarded entity's name if applicable. The "Chapter 3 status" is usually "Corporation," and the form continues into FATCA classification in Part I and treaty claims in Part III.

If you want to claim reduced US withholding under a tax treaty, you must complete the treaty-claim section and have a tax residency in a country that has a treaty with the United States. Without that, the default 30% withholding rate applies to US-source FDAP income.

"But My Income Isn't US-Source — Do I Even Need This?"

A common situation: you are a developer, designer, consultant, or marketer living outside the US, performing all the work outside the US, for a US client. Under US source-of-income rules, services performed outside the US are generally non-US-source income, and your fees are not subject to US tax or US withholding — that is the legal position behind why so many non-residents legitimately owe no US federal income tax on services revenue.

But your US client still wants paperwork. Their payroll or AP system needs a certified document showing why they are not withholding tax and not issuing a 1099. The W-8 is exactly that document. Refusing or sending a W-9 can force the client to apply 24% backup withholding or 30% non-resident withholding as a precaution — money you would then have to chase through a refund process.

Where the Form Goes, and How Long It Lasts

You send the completed W-8BEN or W-8BEN-E directly to the client (the withholding agent). It is not filed with the IRS. The client keeps it on file.

A W-8 form is generally valid from the date signed through the last day of the third following calendar year — so a form signed in 2026 is typically valid until December 31, 2029 — unless your circumstances change (new address, change of citizenship, loss of treaty residency, etc.), in which case you must provide an updated form within 30 days.

The Mistakes That Cost the Most

Three patterns we see repeatedly: signing a W-9 with the LLC's EIN to "just get paid," which puts the LLC into the US-person reporting system it doesn't belong in; entering the LLC's EIN as the TIN on a W-8BEN instead of using your foreign TIN or ITIN, which is the wrong field for a disregarded entity's owner; and claiming treaty benefits on a W-8 from a country whose treaty you don't actually qualify under, which can trigger penalties and back-withholding for both you and your client.

None of these are theoretical — they show up later as 1099-Ks you shouldn't have received, mismatched IRS notices, or clients clawing back withholding from your next invoice.

Have Questions About Your Own Situation?

Every set-up is a little different — the country you live in, whether your LLC is single- or multi-member, whether a foreign company owns it, whether a tax treaty applies.
