W-8BEN vs W-9: Which Form as a Non-Resident LLC Owner
If a US bank, client, or payment platform has asked you for a tax form, picking the wrong one between W-9 and W-8BEN can trigger unnecessary withholding or reporting headaches. Here is how to tell them apart.
The short answer
W-9 is for US persons. That includes US citizens, US tax residents, and US entities that are taxed as domestic corporations. W-8BEN is for foreign individuals who are the beneficial owner of income being paid by a US source. Most non-resident founders who own a single-member US LLC should be filling out a W-8BEN, not a W-9, because for federal tax purposes a foreign-owned single-member LLC is usually a 'disregarded entity' and the tax status that matters is yours, not the LLC's.
This trips up a lot of people because the LLC itself looks American. It has a US Employer Identification Number (EIN), a US registered address, and a US bank account. But an EIN is just an identifier. It does not make you a US person, and it does not change the fact that a disregarded LLC's owner is who the IRS and any withholding agent actually look at.
What each form is actually doing
Both forms exist so that a 'withholding agent', usually whoever is paying you, knows whether to withhold tax on a payment and how to report it to the IRS.
| Form | Who files it | What it tells the payer | Typical result |
|---|---|---|---|
| W-9 | US persons and US entities | 'I am a US taxpayer, here is my TIN' | No withholding, payer may issue Form 1099 |
| W-8BEN | Foreign individuals (beneficial owners) | 'I am not a US person, here is why no withholding or reduced withholding applies' | Payer may withhold 30 percent on US-source FDAP income unless a treaty reduces it, no 1099 issued |
| W-8BEN-E | Foreign entities | Same idea as W-8BEN but for a company rather than an individual | Used when the foreign owner is itself a corporation, not a person |
Notice the forms are given to the payer, not filed with the IRS directly. Your bank, payment processor, or client keeps it on record and uses it to decide whether to withhold.
Where the confusion comes from
US banks and payment platforms are built around domestic customers, so their onboarding flows often default to asking everyone for a W-9. Mercury, Wise, and Relay all onboard non-resident founders remotely and generally understand foreign ownership, but some forms and third-party integrations still surface a W-9 request by default. If you are a non-resident owner of a disregarded single-member LLC, the correct form is a W-8BEN completed in your personal capacity as the beneficial owner, not a W-9 for the LLC.
The one case where a US-looking form is genuinely correct is if your LLC has elected to be taxed as a corporation (via Form 8832 or 2553), in which case the entity itself may need to provide a W-8BEN-E or, if it has become a domestic corporation for tax purposes in some structuring scenarios, different rules apply. For the vast majority of founders using the default single-member LLC setup, this does not apply.
Withholding basics you should actually understand
There are three separate withholding concepts, and mixing them up is where most confusion happens.
- Backup withholding (24 percent) applies to US persons who fail to provide a correct W-9 or TIN. This is not something a properly documented non-resident founder needs to worry about.
- FDAP withholding (up to 30 percent) applies to certain US-source income paid to foreign persons, such as interest, dividends, royalties, and some types of passive or fixed income. A correctly completed W-8BEN lets the payer apply a reduced treaty rate or confirm no withholding is due, depending on the income type and your country's tax treaty with the US.
- Effectively connected income (ECI) is income connected to an actual US trade or business. If your LLC has ECI, different withholding and reporting rules apply, including possible withholding under section 1446 for partnerships. Most non-resident founders running an online service business with no US employees, office, or dependent agent do not have ECI, but this depends on your specific facts and is worth getting right rather than assuming.
Importantly, a W-8BEN is a certification about status, not a tax calculation. It does not determine how much tax you ultimately owe, it determines what a payer withholds at the point of payment. Your LLC's actual US tax position is separate and still requires attention.
Do not forget the LLC's own filing obligation
Sorting out W-8BEN versus W-9 for a bank or client is unrelated to your LLC's annual federal filing duty. A foreign-owned single-member LLC that is disregarded for tax purposes must still file Form 5472 along with a pro-forma Form 1120 every year, even if the LLC had zero income or did nothing at all. Missing this filing carries a penalty of 25,000 dollars, and it is one of the most common and costly mistakes non-resident founders make because they assume 'no income means no filing.'
This is a large part of why Founders Credit exists as a done-for-you service. We set up the LLC (commonly in Wyoming, the standard low-cost default for non-resident founders), obtain the EIN, help you get an ITIN, open a US business bank account and cards, and make sure the ongoing federal filings like Form 5472 actually get done, not just the initial paperwork.
Quick glossary
W-9: form used by US persons to certify their taxpayer status to a payer. W-8BEN: form used by a foreign individual to certify non-US status, often to claim a reduced withholding rate under a tax treaty. W-8BEN-E: the entity version of W-8BEN, used by foreign companies. FDAP income: fixed, determinable, annual, or periodical income such as interest, dividends, and royalties, subject to 30 percent withholding for foreign persons unless reduced by treaty. ECI: effectively connected income, income tied to an actual US trade or business, taxed differently from FDAP. Backup withholding: 24 percent withholding applied to US persons who fail to provide valid W-9 information. Disregarded entity: a single-member LLC that is ignored for federal tax purposes, with tax attributes passing through to the owner. ITIN: an individual taxpayer identification number for people who need a US tax ID but are not eligible for a Social Security Number and do not need a visa to obtain one. EIN: the business tax identification number for your LLC, obtained via Form SS-4, which non-residents can typically apply for by fax or mail. Form 5472: the annual information return a foreign-owned disregarded LLC must file alongside a pro-forma 1120.
Practical takeaway
If you are a non-resident individual who owns a US LLC directly and the LLC has not elected corporate tax status, give out a W-8BEN in your own name when a US payer asks. Reserve the W-9 for situations where you are genuinely a US person or your entity has elected to be treated as a domestic corporation. When in doubt, ask whoever is requesting the form what type of income the payment relates to, since that affects which treaty article or exemption may apply.
Frequently asked questions
Do I need an ITIN before I can complete a W-8BEN?
Not always. A W-8BEN can be submitted with a foreign tax identification number in many cases. However, if you want to claim a reduced withholding rate under a tax treaty for certain income types, a US ITIN is often required, so most non-resident founders get one early rather than dealing with it payment by payment.
My US bank asked me to fill out a W-9 for my LLC, is that wrong?
It depends on your LLC's tax classification. If your single-member LLC is disregarded and you are a non-resident individual, the technically correct form is a W-8BEN in your personal name as beneficial owner. Some bank onboarding systems default to W-9 regardless, so it is worth checking with the bank or your accountant rather than assuming their default form is correct for your situation.
What actually happens if I submit the wrong form?
Submitting a W-9 when you should have submitted a W-8BEN can result in incorrect 1099 reporting and can create confusion about your tax residency status. Submitting a W-8BEN when a W-9 was appropriate can trigger unnecessary 30 percent withholding on payments. Neither mistake is usually fatal, but it can cause delayed payments or a messy paper trail to correct later.
Does a W-8BEN mean I pay no US tax at all?
No. A W-8BEN only affects withholding at the point a payer sends you money, and only for certain categories of US-source income. It does not replace your LLC's own federal filing obligations, including Form 5472 and a pro-forma 1120 for a foreign-owned disregarded LLC, and it does not determine your actual tax liability.
How often do I need to renew a W-8BEN?
A W-8BEN is generally valid through the end of the third calendar year after it is signed, unless your circumstances change before then, such as a change in tax residency. Payers will usually prompt you to resubmit one once it expires.
