W-8BEN vs W-9: Which Form Are You?
A US platform is holding your payout hostage until you fill in a tax form — and it offers a W-9 and a W-8BEN without explaining which is yours. The answer is simpler than it looks: one form is for US persons, the other for foreigners. Here's how to know which you are.
Why a platform asks in the first place
When a US company pays you — a marketplace, a payment processor, an ad network, an affiliate program — US rules make them responsible for knowing whether you are American or foreign for tax purposes. They can't just take your word for it in an email; they need it on an official IRS form they can keep on file. That single question — "are you a US person or not?" — is what the whole W-9 versus W-8 choice is really asking. You aren't being taxed twice or signed up for anything; you're telling the payer which set of rules applies to money they send you.
W-9: the form for US persons
The Form W-9 is for a US person — a US citizen, a US resident for tax purposes, or a US company. All it really does is hand the payer your name and your US taxpayer number (an SSN or EIN) so that, if they later have to report what they paid you, they can. If you are not a US person, the W-9 is simply the wrong form — signing one would tell the IRS you are American when you are not, which is a mistake you want to avoid.
W-8BEN: the form for foreign individuals
The Form W-8BEN is the mirror image: it is how a foreign individual — a person who is not a US citizen or resident — tells the payer "I'm not a US taxpayer." It records your name, your country, and (if it applies) a claim to a lower tax rate under a tax treaty between your country and the US. If you're an individual living outside the US earning money from a US platform, this is almost always your form. If the family of tax ID numbers is fuzzy, our guide to EIN vs ITIN vs SSN lines them up, and what an ITIN is covers the personal number a W-8BEN sometimes needs.
W-8BEN vs W-8BEN-E — person vs company
Here's the distinction that catches people: the "-E" version. A plain W-8BEN is for a foreign individual (a human being). A W-8BEN-E is for a foreign entity (a company). The letter E stands for "entity," and it's a much longer form because it also asks about the company's classification and status. So the rule of thumb is: if you personally are the one being paid, you file a W-8BEN; if a foreign company you own is the one being paid, that company files a W-8BEN-E. Picking the wrong one of the two is one of the most common reasons a platform bounces the paperwork back.
The single-member-LLC twist
Now the part that genuinely confuses foreign founders. Say you're a non-resident who owns a US single-member LLC. Your instinct is: "My LLC is a US company, so it files a W-9, right?" Usually no. A single-member LLC is, by default, a "disregarded entity" — the IRS looks straight through the company to its owner and treats the two as one for this purpose. Because the owner is you, a foreign person, the payer typically needs a W-8BEN in your name (with the LLC's details noted on it), not a W-9. The US mailing address and US LLC don't make you a US person; only your own tax status does. It feels backwards, which is exactly why it's worth getting a second opinion before you sign.
How long each form lasts
A W-9 generally has no expiry — you redo it only when your information changes, such as a new name or a new taxpayer number. A W-8BEN expires: as a general rule it stays valid until the end of the third full calendar year after you sign it (so one signed in 2026 lapses at the end of 2029), and sooner if anything on it changes. When it lapses, the platform will ask for a fresh one — and if you ignore the request, they may start withholding tax on your payouts, so it's worth renewing before the deadline rather than after.
Withholding, in one paragraph
"Withholding" just means the payer holds back a slice of your money and sends it to the IRS instead of to you. For certain US-source income paid to foreigners, the default rate is a flat 30%. A valid W-8BEN is what lets the payer apply a lower treaty rate — or confirm no US tax applies — instead of defaulting to 30%. That's the practical reason the form matters: filed correctly, it can be the difference between receiving your full payout and watching nearly a third of it disappear into withholding. It does not, by itself, decide your final tax bill — it just sets what's held back up front.
So — which are you?
Quick version: a US citizen, US resident, or US company files a W-9. A foreign individual files a W-8BEN. A foreign company files a W-8BEN-E. A non-resident who owns a US single-member LLC usually files a W-8BEN, because the LLC is disregarded and you are still foreign. If more than one of those could describe your setup, that's the signal to check rather than guess.
What we handle for you
We tell you which form your exact situation calls for, fill it in so it survives the platform's review, and set up any treaty claim so your withholding is right from the first payout — a routine part of our e-commerce & Amazon practice and our US market-entry service. If a form leads to a payout report, our companion guide to the 1099-K for foreign sellers explains what shows up at tax time. Send us the form the platform is asking for and we'll tell you which box you belong in.
