The W-8 Form is a document that allows foreign investors to avoid double taxation on the dividends they receive from their investments in the U.S. Without this form, they would automatically be taxed in the U.S. and then have to pay taxes again when declaring those earnings in their country of residence.
The U.S. withholds 30% of dividends from non-residents. If your country has a tax treaty with the U.S., the W-8BEN form can reduce that withholding (for example, 15% in Chile and 10% in Mexico).
How to Complete the W-8 Form?
The W-8BEN is completed when you open your account, with your tax identification number, and is valid for 3 years. If it is not current, Apex may withhold 24% of a sale (backup withholding); you will see it as "W8-BEN Tax".
