- 4Not signing the Part II certification, rendering the form invalid.

Plain English
Form W-8ECI tells a U.S. payer that the foreign person’s income is tied to a U.S. trade or business, so normal 30% withholding does not apply. The foreign party fills in its name, address, and a U.S. tax ID, then signs. The completed form is given to the payer before any payment is made.
