The first invoice to a US client often comes with a request: “Please send us your W-9.” Your LLC is a US company with a US EIN, so a W-9 sounds right. For a single-member LLC owned by someone who lives outside the US, it usually is not. This guide explains the IRS rule, which form fits which owner, and how to fill it in so the client does not withhold tax by mistake.
The short answer
| Who owns the single-member LLC | Form the owner gives the US payer |
|---|---|
| A non-US individual (you) | Form W-8BEN, in your own name |
| A foreign company | Form W-8BEN-E, in the company’s name |
| Either, if the income is ECI | Form W-8ECI |
| A US person | Form W-9, from the US owner |
| Multi-member LLC (a partnership) | The LLC itself; a domestic partnership gives a W-9 |
ECI means effectively connected income: profit from a US trade or business. Most founders who do the work from outside the US do not have it.
Why the owner, not the LLC, signs the form
A single-member LLC is a disregarded entity for US tax unless it elects corporate treatment. The withholding rules follow that: the IRS looks through the LLC to its owner.
The IRS says it directly. The Form W-8BEN instructions state: “The owner of a disregarded entity (including an individual), rather than the disregarded entity itself, must submit the appropriate Form W-8BEN.” The W-8BEN-E instructions say that for a disregarded entity with a single owner, “the single owner, if such owner is a foreign person, should provide Form W-8BEN or Form W-8BEN-E (as appropriate). If the single owner is a U.S. person, a Form W-9 should be provided.” (IRS, Instructions for Form W-8BEN and Instructions for Form W-8BEN-E, checked October 2026.)
So a W-9 signed in the LLC’s name tells the client that a US person receives the income. For a foreign-owned disregarded LLC, that is not accurate.
What the form changes for the client
A US company that pays a foreign person may have to withhold US tax, usually 30%, on certain US-source income: royalties, interest, rent and similar payments. The W-8 form tells the payer who the real recipient is, whether withholding applies, and whether a treaty lowers the rate.
For services, the key point is where you do the work. Pay for services you perform outside the US is generally foreign-source income, so there is usually no US withholding on it. A W-8BEN that shows you are a foreign person documents exactly that. The client also files a Form 1042-S, instead of a Form 1099, for some payments to foreign persons.
How to fill in Form W-8BEN as an LLC owner
Use your own details, as the individual owner:
- Line 1, name: your full name as on your passport.
- Line 2, country of citizenship.
- Line 3, permanent residence address: your home address abroad. Not a US mailing address and not a P.O. box.
- Line 4, mailing address: only if different.
- Line 5, US taxpayer ID: your SSN or ITIN if you have one. Leave blank if you do not and are not claiming a treaty benefit that requires it.
- Line 6a, foreign tax ID: your tax number in your country of residence.
- Line 9 and 10, treaty claim: only if you claim a reduced rate under a tax treaty, for example on royalties.
- Sign and date in Part III.
Many clients’ systems also ask for the LLC’s name and EIN. You can give them in a cover note or the client’s own onboarding form, and invoice in the LLC’s name. Keep the W-8BEN itself in your name, as the instructions require.
When W-8BEN-E applies instead
If a foreign company owns your LLC, the foreign company is the owner for withholding purposes. It gives a Form W-8BEN-E with its own name, country and chapter 4 status. Part II of the W-8BEN-E has a place to name a disregarded entity that receives the payment, which is used mainly in specific banking cases. Our guide to foreign corporations owning a US LLC explains that structure.
When W-8ECI applies
If the payments are effectively connected with a US trade or business, for example because you do the work while in the US, the owner gives Form W-8ECI. That form requires a US taxpayer identification number, generally an SSN or ITIN for an individual. It tells the payer not to withhold, because you will report the income on Form 1040-NR. See foreign-owned LLC taxes for how to tell.
When a W-9 is right
- The LLC has a US owner: the US owner gives a W-9.
- The LLC elected to be taxed as a corporation (Form 8832): it is then a US corporation for tax and gives a W-9 in its own name, with its EIN.
- The LLC has two or more members and is a partnership: a US partnership gives a W-9 in its own name.
Platforms and marketplaces
Upwork, Amazon, app stores and payment processors run their own tax interviews. The questions are the same underneath: who owns the company, is it disregarded, where is the owner resident, and where is the work done. Answer them the same way every time, and keep a copy of what you submitted.
FAQ
My client insists on a W-9. What do I do?
Explain that the LLC is a disregarded entity with a foreign owner, and that the IRS instructions ask the foreign owner to provide a W-8BEN. Share the instruction quote above. Most payroll and accounts teams accept it once they see the rule.
Does giving a W-8BEN mean the client will withhold 30%?
Not for payments for services you perform outside the US, which are generally foreign-source. Withholding applies mainly to US-source payments like royalties, interest or rent, and a treaty can reduce it.
Do I need an ITIN to fill in a W-8BEN?
Not usually. An ITIN is needed on a W-8BEN mainly when you claim treaty benefits, and on a W-8ECI. Our ITIN guide explains when you need one.
How long is a W-8BEN valid?
Generally until the end of the third calendar year after you sign it, unless your situation changes first. Give the payer a new one if you move country or your details change.
Do payments from clients go on Form 5472?
No. Form 5472 reports transactions between the LLC and its foreign owner and other related parties, not payments from unrelated clients. See related party transactions.
Our Accounting plan keeps each client payment, owner contribution and withdrawal recorded, so the figures for your forms and your yearly Form 5472 come from one set of books. Federal filing is a separate service, or included in Full Compliance. If a client or platform sends you a form you are unsure about, ask us which one fits your company.
