Form W-8BEN

What the form certifies, and why a payer asks for it

Form W-8BEN does two jobs. The first is to establish foreign status. The IRS describes the purpose for chapter 3: foreign persons are subject to US tax at a 30% rate on income they receive from US sources, including compensation for services performed. The form tells the payer that the person being paid is one of those foreign persons, and not a US person who should be on a Form 1099.

The second job is to claim treaty benefits. Part II of the form is where a resident of a treaty country names that country, and line 10 adds the details for treaty claims whose conditions the standard certification does not cover.

For most foreign contractors, only the first job matters. IRS Publication 515 says that for personal services, “The place where the services are performed determines the source of the income, regardless of where the contract was made, the place of payment, or the residence of the payer.” A designer in Portugal who works from Portugal for a US company earns foreign-source income from that work. There is no US tax to withhold on it, so the W-8BEN is simply the record that explains why the company withheld nothing and issued no Form 1099.

That record matters later. If a contractor who looks foreign cannot be documented as foreign, a payer can end up treating them as a US person with no taxpayer identification number, which is the trigger for backup withholding.

How long a W-8BEN stays valid

A W-8BEN does not last forever, and it does not run for a fixed number of months. The IRS rule is that the form “will remain in effect for purposes of establishing foreign status for a period starting on the date the form is signed and ending on the last day of the third succeeding calendar year, unless a change in circumstances makes any information on the form incorrect.”

The IRS gives its own example: a form signed on September 30, 2015, remains valid through December 31, 2018. Applied to today, a contractor who signs on March 15, 2026 is covered through December 31, 2029. A form signed on January 2, 2026 expires on the same day. The date in the year makes no difference, only the year.

A change in circumstances cuts that short. The instructions require the payee to notify the payer within 30 days of the change and to give a new form. For someone using the form to certify foreign status, a change of address to an address in the United States is a change in circumstances. A move within the same foreign country, or to another foreign country, generally is not, unless the form claims treaty benefits for the country being left.

The practical result is a renewal calendar. Sort contractors by the year their form was signed, and request new forms before each group’s December 31.

W-8BEN, W-8BEN-E, W-9 or Form 8233: which form fits

The W-8BEN instructions list who should not use it, and each exclusion points to a different form.

A foreign entity uses Form W-8BEN-E. If your contractor invoices through a limited company, a GmbH or any other entity, the entity is the payee, and the entity documents its own status.

A US citizen or other US person, including a resident alien, uses Form W-9, even if they live outside the United States. A US citizen working from Lisbon is still a W-9 contractor and still gets a Form 1099.

A nonresident alien who claims an exemption from withholding on compensation for personal services performed in the United States uses Form 8233. This is the case where the work happens on US soil and a treaty is being used to avoid the 30%. Publication 515 says a withholding agent that accepts a Form 8233 must sign it and forward it to the IRS within 5 days. The form only covers the exemption it claims.

Income that is effectively connected with a US trade or business goes on Form W-8ECI instead. That is uncommon for an individual contractor working abroad, but it is the form for a foreign person operating a business in the United States.

Collecting W-8BEN forms on Stripe Connect

On a Stripe Connect platform that pays contractors, the platform is the payer, so collecting and keeping these forms is the platform’s job. Stripe offers a product for it. Its W-8 and W-9 Connect documentation says a W-8 “is for non-US tax residents and is used to certify their name, address, and foreign TIN (if applicable), to confirm that they’re not a US taxpayer.” Access is limited to US preview users.

The platform decides when to ask. It can collect the form at onboarding, or request it later through the Accounts API. It can also set an enforcement threshold that blocks payouts until the form is submitted: after a volume of processing in US dollars, after a number of days, or whichever comes first. Submitted forms can be downloaded as PDFs from the Stripe Dashboard.

The form on file also decides what Stripe does at year end. Stripe’s support article on 1099 details says that if the most recent form on file for a connected account is a W-8, the account won’t automatically receive a 1099. If a US contractor submitted a W-8 by mistake, Stripe’s fix is to request a W-9 and confirm a certified W-9 is on the account.

Platforms without access to the preview collect the form outside Stripe, usually as a signed PDF or through an e-signature tool, and keep it with the contractor’s records. Either way, the form is a record you keep, not one you file.
