Form W-8BEN (Certificate of Foreign Status of Beneficial Owner)

US payers must generally withhold 30 percent on US-source income paid to foreign persons, including interest, dividends, royalties, and payments for services performed in the United States. A valid Form W-8BEN establishes that the recipient is a foreign individual, supplies a foreign taxpayer identification number or US TIN, and can claim treaty benefits that reduce or eliminate withholding for a specified income type.

For employers, the form comes up most often with foreign contractors. If a foreign individual performs all services outside the United States, the payment is generally foreign-source and not subject to US withholding or 1099 reporting, but you still collect the W-8BEN as documentation of why nothing was withheld. If any of the work happens on US soil, the picture changes and reporting on Form 1042-S usually applies. A foreign person who is actually an employee runs through expatriate payroll, with Form 8233 used for treaty claims on personal services.

A W-8BEN is valid through the third full calendar year after signing unless circumstances change, so build a refresh cycle into your vendor file. The recurring mistake is collecting a Form W-9 from a foreign contractor simply because it is the familiar form, which misstates the payee's status and leaves the withholding agent liable for tax it failed to withhold.

Frequently asked questions

Should I collect a W-8BEN or a W-9 from a foreign contractor?

A W-8BEN. Using a W-9 because it is the familiar form misstates the payee's status and can leave the withholding agent personally liable for tax it failed to withhold. The W-8BEN documents foreign status, supplies a taxpayer identification number, and supports any treaty claim that reduces the standard withholding rate.

Do I withhold on services performed entirely outside the United States?

Generally no. Payments for services a foreign individual performs entirely abroad are usually foreign-source, so they fall outside US withholding and information reporting. You still collect the certificate to document why nothing was withheld. Once any part of the work happens on US soil, withholding and reporting obligations change.

How long does a W-8BEN stay valid?

Through the third full calendar year after it is signed, unless something changes that makes the information unreliable before then. Build a refresh cycle into the vendor file so certificates do not quietly expire between engagements. A payee whose circumstances change has to provide a new form promptly.
