You can facilitate the process by having the foreign payee submit a completed IRS W-8 form to confirm that the vendor is foreign. If the payee does not complete the IRS W-8 form, you must provide the foreign address, and include any documentation showing the foreign payee's name and address. All foreign vendor requests are routed to DFA’s Tax Office after the Disbursement Voucher has been approved by the fiscal officer. Refer to Buying Manual section 205, Vendor Setup.
