International suppliers have separate approval requirements dependent on their Visa type, reason for payment and location where service/activity will be performed.

Homeland Security (IRS, U.S. Immigration, and Department of Treasury) dictates taxation rules, treaty eligibility, and work authorizations that we must abide by when paying foreign individuals/entities.

All international suppliers will be paid via wire transfer. Wire information will be collected at the time of registration. International suppliers should have the appropriate tax documentation current and readily available:

• • • Form W-8BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding.
    • W-8BEN-E, Certificate of Status of Beneficial Owner for United States Tax Withholding (Entity).
    • Form W-8ECI, Certificate of Foreign Person's Claim That Income Is Effectively Connected with the Conduct of a Trade or Business in the United States.
    • Form W-8EXP, Certificate of Foreign Government or Other Foreign Organization for United States Tax Withholding.
    • Form W-8IMY, Certificate of Foreign Intermediary, Foreign Flow-Through Entity, or Certain U.S. Branches for United States Tax Withholding.
