What are your experiences with Form W-8BEN

tags: Tax, European, W-8BEN

The purpose of the Form W-8BEN and Form W-8BEN-E is to establish your identity and status as a non-U.S. person. If you do not submit your tax information, the IRS requires Envato to assume that you are a US person and we have to apply the 24% backup withholding tax.

Do we have a few Europeans in here who could share their experiences with these forms?
Is it worth the hassle?
