The University of Colorado is closely monitoring the situation in Israel, Gaza, and the West Bank as it affects University travel. Many airlines have already cancelled or suspended flights, and traveler advisories are changing regularly. For the most up-to-date information on worldwide travel advisories and how those impact any University business travel planning, please refer to the US Department of State Travel Advisories page.
CU travelers are also encouraged to utilize ISOS Membership Services (enter CU’s Membership No. 11BCAS000006 to log in) as an additional resource. To receive updated notifications dependent on your travel destination, download the ISOS mobile app. Note: All travel booked through Concur/CBT is automatically registered with ISOS.
External suppliers -- including suppliers who are foreign nationals or foreign entities -- register online through the CU Supplier Portal in order for the University to make payment for goods or services rendered. The CU Supplier Portal is available through the University's eProcurement system, CU Marketplace.
As part of the online registration process, the supplier uploads the appropriate W-9 or W-8 tax document. For foreign suppliers, this will be one of the versions of the IRS W-8 form.
The W-8 Forms on the IRS website are available within the CU Supplier Portal.
We recommend that suppliers use the Portal-generated tax document, as it will pre-populate the information provided during the registration process into the appropriate area of the W-8 form.
To view the versions of the W-8 form, and their instructions, directly on the IRS website, go to www.irs.gov. Click the “Forms & Pubs” tab within the top menu, then select “Current Forms & Pubs” and enter “W-8” into the search field to access the current versions of the W-8. (Or go directly to the W-8 search page at http://apps.irs.gov/app/picklist/list/formsPublications.html;jsessionid=....)
Please note that neither the Procurement Service Center nor the International Tax Office has the legal authority to advise foreign suppliers as to which W-8 form is most appropriate.
For questions about W-8 form requirements, contact the International Tax Office: intltax@cu.edu
