UW Supplier Registration
A current UW Supplier Registration must be on file in order to do business with the University of Washington.
All suppliers must complete a UW Supplier Registration Form online. Please see the Supplier Registration Form page to access the SRF.
Please note the UW Supplier Registration is distinct and separate from the WEBS registration requirement
Foreign Nationals and Foreign Entities
Foreign entities should complete an W-8BEN when performing services within the United States. Departments on campus should collect the original and forward it to the NRA Tax Desk in Accounts Payable.
Foreign entities selling products and/or performing services outside the United States are not required to fill out the Supplier Registration form or any other IRS document unless it is a copywrite or royalty payment.
Taxpayer Identification Number (TIN) & Supplier Name Verification
Effective July 1st, 2010, Procurement Services implemented a new procedure to verify that the Taxpayer ID number and the name of any 1099 reportable supplier is consistent with Internal Revenue Service (IRS) information.
The IRS matches the information we provide on a supplier's 1099 MISC form with information the supplier reports on their federal income tax return. Any differences, however insignificant, may result in IRS penalties. In order to avoid penalties, it is imperative that the information provided to the UW on a Supplier/Vendor Registration form (or W9) matches EXACTLY with how it appears on the income tax return submitted to the IRS.
When a new supplier is added to the UW system, we are verifying with the IRS that the information provided on the supplier registration form matches their database. If it does not match, we will hold the supplier registration (along with any payments) until the correct information is received and confirmed. The UW will be making every effort to ensure that the information we will be reporting to the IRS is a match prior to making payments. Please refer to the instructions at www.irs.gov/pub/irs-pdf/iw9.pdf for more information on which information should be provided in which cases.
If you are a sole proprietor or disregarded LLC, you must enter your individual name on the first line of the Supplier Registration and any business name on the second line, if applicable.
