Payments to Foreign Vendors
The University is required to establish the tax status of foreign entities with which it conducts business. The W-8BEN submitted by a foreign entity indicates whether taxes need to be withheld when payments are processed. Transactions that may trigger tax withholding include services performed in the US, and US-sourced royalties and rents. A foreign entity from a country that has negotiated a tax treaty may be exempt from tax on certain types of transactions. If they are from a country with no treaty benefits, or the activity is not covered by the treaty, payment to the vendor is subject to 30% tax withholding.
All foreign vendors are placed on a payment "hold" to ensure that all requests for payments are reviewed for tax compliance prior to payment being processed.
Each W-8BEN is reviewed for tax status determination, and each invoice submitted for payment is reviewed by Accounts Payable for taxable-type transactions.
Payments to foreign vendors are made via U.S dollar checks, and by electronic funds transfer in U.S. dollars or the foreign currency. The process for paying a foreign vendor is described in the Electronic Funds Transfers Policy.
