W-8 form basics
W-8BEN vs W-9: which form a payer needs from you, and why the difference is U.S. status
A U.S. client asks for 'a W-9 or W-8'. The answer does not depend on where you live or where the client is. It depends on whether you are a U.S. person under U.S. tax law.
Form W-9 and Form W-8BEN answer the same question from opposite sides. A U.S. payer must know whether the person it pays is a U.S. person or a foreign person, because the reporting and withholding rules differ. Form W-9 says “I am a U.S. person, here is my taxpayer number.” Form W-8BEN says “I am not a U.S. person, and here is the treaty rate I am entitled to, if any.”
Only one of them can be right for you, and the deciding fact is your status, not your address, your bank, or your client’s location. This guide is educational information, not tax advice.
The one-minute version
| Comparison | Form W-9 | Form W-8BEN |
|---|---|---|
| Who uses it | A U.S. person: citizen, resident alien, or U.S. entity | A foreign individual who owns the income |
| What it certifies | U.S. status and a correct taxpayer identification number | Foreign status, beneficial ownership, and optionally a treaty rate |
| Number required | SSN, ITIN, or EIN, always | Foreign TIN for a treaty claim; U.S. TIN only in narrow cases |
| What the payer does with it | Reports payments on Form 1099; no withholding unless backup withholding applies | Withholds 30% or a treaty rate on U.S.-source income and reports on Form 1042-S |
| Consequence of not providing it | Backup withholding, currently 24% | 30% withholding, and possibly backup withholding on everything |
| Expiry | Does not expire while the information stays correct | December 31 of the third year after signature |
| Entity version | The same Form W-9 | Form W-8BEN-E |
What “U.S. person” means
The IRS definition drives everything. For an individual, you are a U.S. person if you are a U.S. citizen or a resident alien. You are a resident alien if you hold a green card or if you meet the substantial presence test, which counts the days you were physically in the United States over a three-year window.
Two consequences surprise people.
- A U.S. citizen living abroad is still a U.S. person. A citizen in Lisbon, Toronto, or Bengaluru gives Form W-9, not W-8BEN. Living outside the country changes nothing.
- A non-citizen living inside the United States may be a U.S. person. Someone on a work visa who has been in the country most of the year usually meets the substantial presence test and gives Form W-9, even though they hold a foreign passport. Students and certain other visa holders are “exempt individuals” whose days do not count for a period, which is why a foreign student can remain a nonresident and use W-8BEN or Form 8233.
The IRS pages on tax residency and the substantial presence test, linked in the sources, set out the day counts and the exceptions.
Which form does your status point to?
A summary of the U.S. person rules for individuals. Dual-status years, treaty tie-breakers, and exempt-individual periods need the IRS pages or professional advice.
Are you a U.S. citizen?
Do you hold a green card (lawful permanent residence)?
Were you physically in the U.S. enough days to meet the substantial presence test?
Roughly, 31 days this year and 183 days over this year and the two before it, with the earlier years counted at one third and one sixth.
You are probably a resident alien: Form W-9
Unless a treaty tie-breaker or an exempt-individual rule applies, which needs advice.
Form W-9
You are a U.S. person. Wherever you live, give the payer Form W-9 with your SSN or ITIN.
Form W-8BEN (individual) or W-8BEN-E (entity)
You are a foreign person. Certify that status with the W-8 form that matches who receives the income.
What each form does for the payer
A U.S. business that pays a contractor, a royalty, or interest must report the payment and, in some cases, withhold tax. The two forms tell it which regime applies.
With a Form W-9 on file, the payer treats you as a U.S. taxpayer. It reports the year’s payments to you and to the IRS on a Form 1099, and it withholds nothing unless the IRS has told it to apply backup withholding, or you failed to give a correct TIN. Backup withholding is 24% at the time of review.
With a Form W-8BEN on file, the payer treats you as a foreign person. It withholds 30% of U.S.-source income of the kinds subject to withholding, or a lower treaty rate if you claimed one, and reports the payment and the tax on Form 1042-S. Payments for services you perform outside the United States are foreign-source and are not subject to withholding at all.
With neither on file, the payer is exposed. The W-9 instructions tell the requester to apply backup withholding, and the W-8BEN instructions warn that a foreign person without a form faces withholding at 30% or the backup rate. That is why a platform will not release your first payout until it has one of the two forms.
Choosing wrong in each direction
A foreign person who signs a W-9 has certified, under penalties of perjury, that they are a U.S. person. The payer will report the income on a Form 1099 under whatever number was given, which for a non-U.S. person is usually a number that does not belong to them or does not exist. Expect the payer to reject the form or come back later with an IRS notice about a name and TIN mismatch. Correcting it means giving the payer a W-8BEN and asking for the 1099 to be voided.
A U.S. person who signs a W-8BEN has certified the opposite. The payer withholds 30% on U.S.-source income and reports it on Form 1042-S. Because the person is actually a U.S. taxpayer, that income still belongs on their Form 1040, and the tax withheld is recovered there. The certification itself is false, which is the more serious problem. The fix is a Form W-9 to the payer as soon as the error is found.
Platforms build a status question into their tax tools for exactly this reason. Google’s tax tool asks “Are you a citizen or resident of the United States?” before showing either form, and Amazon’s interview and Patreon’s settings do the same.
Where each form is used
Both forms appear in the same places: marketplace onboarding, broker account opening, bank accounts, royalty platforms, and direct requests from clients. The request often arrives as “please complete a W-9 or W-8”, and the payer expects you to know which. Some situations tilt one way.
- Freelancers on Upwork, Fiverr, and similar platforms who live outside the United States and are not U.S. citizens give W-8BEN. The platform then issues no 1099, and because the work is performed abroad there is normally no withholding.
- Creators on YouTube, Twitch, Patreon, and KDP who are not U.S. persons give W-8BEN inside the platform’s tax tool. The use-case guides cover each platform.
- Investors at U.S. brokers give W-8BEN, renew it every three years, and claim the treaty dividend rate on Line 9.
- U.S. citizens abroad in any of those roles give W-9. Their foreign address goes on the W-9; the form has no rule against it.
A U.S. citizen can live and work outside the United States and still be a U.S. person. Establish your U.S. tax status before choosing between W-9 and W-8BEN.
Worked examples
Nadia, a Canadian citizen in Vancouver, designs logos for a U.S. agency. She is not a U.S. citizen, holds no green card, and has spent no days in the United States this year. She gives Form W-8BEN. The work is done in Canada, so no U.S. tax is withheld.
Marcus, a U.S. citizen in Berlin, edits videos for a U.S. production company. Living in Germany does not make him a foreign person. He gives Form W-9 with his SSN and reports the income on his U.S. return, along with any German tax he pays.
Priya, an Indian citizen on an H-1B visa in Austin, sells stock photos to a U.S. agency. She has been in the country all year and meets the substantial presence test, so she is a resident alien. She gives Form W-9.
Kenji, a Japanese student on an F-1 visa in Boston, receives a research stipend. Days on an F-1 visa are exempt from the presence test for his first five calendar years, so he remains a nonresident. Depending on the payment, he gives W-8BEN or Form 8233, not W-9.
Frequently asked questions
What is the difference between a W-9 and a W-8BEN?
Form W-9 is completed by U.S. persons, meaning citizens, resident aliens, and U.S. entities, to give a payer their taxpayer identification number. Form W-8BEN is completed by foreign individuals to certify that they are not U.S. persons and, optionally, to claim a tax treaty rate. A payer needs one or the other before paying you.
I live outside the United States. Do I use W-9 or W-8BEN?
Your address does not decide it. If you are a U.S. citizen or green-card holder you are a U.S. person and use Form W-9 wherever you live. If you are neither, and you do not meet the substantial presence test, you are a foreign person and use Form W-8BEN.
Can a non-U.S. citizen fill out a W-9?
Yes, if they are a resident alien, meaning they hold a green card or meet the substantial presence test. Someone on a long-term work visa living in the United States is usually a resident alien and gives Form W-9. A non-citizen living outside the United States is normally a foreign person and gives Form W-8BEN.
What happens if I fill out a W-9 instead of a W-8BEN?
You have certified that you are a U.S. person, which is false if you are not. The payer will report your income on Form 1099 under the number you gave and may later receive an IRS mismatch notice. Correct it by giving the payer a Form W-8BEN and asking for the 1099 to be voided.
Does a U.S. citizen living abroad need a W-8BEN?
No. A U.S. citizen is a U.S. person regardless of residence and gives Form W-9. Signing a W-8BEN would be a false certification of foreign status.
Do I send a W-9 or W-8BEN to the IRS?
Neither. Both forms go to the person or company that asked for them, which keeps them on file. The payer, not you, reports to the IRS, on Form 1099 for W-9 recipients and Form 1042-S for W-8BEN recipients.
Which form does a foreign company use?
Neither of these two. A foreign entity uses Form W-8BEN-E, the entity version of W-8BEN. A U.S. entity uses Form W-9. Sole proprietors are individuals and use W-9 or W-8BEN according to their own status.
