As a non-U.S resident who earns income from a U.S-based online affiliate programs, you will be asked to submit a W-8BEN form. The W-8BEN form is the "Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding".
This form is required so that we don't need to withhold deductions from your affiliate income. Without this form, we are required to withhold 30% of your payments.

This form states that you are not a U.S. resident, that you are are owner of the income you are receiving, and that you ask that we not withhold U.S. taxes from your income.
This form is actually very simple to fill out if you are an individual and NOT a corporate or legal entity. There are many boxes on the form, but individuals only need to fill out a few of them.
Here are the instructions for completing this form for individuals:
P.O. Box 130
