How long is the W-8 BEN form valid for?

The W-8 BEN form without a provided U.S. tax identification number is valid from the signing date until the last day of the third calendar year, typically three years.

If there are any changes that render the information on the form incorrect, the form becomes invalid. Close to the end of the three-year period, you will receive an email requesting you to resubmit the W-8 BEN form.
