How can you file W-8BEN tax form?

Form W-8BEN [Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding] is used by foreign persons and entities ['beneficial owners'] to claim a reduced rate of or exemption from withholding because they're residents of foreign countries with which the United States has an income tax treaty. Form W-8BEN isn't filed with the IRS. Instead, the beneficial owner gives the completed Form W-8BEN, prior to payment, to the agent or payer who's responsible for issuing payment to the beneficial owner.
