Supplier Registration

ACH Enrollment for Vendors

ACH enrollment allows Cornell to securely and economically pay vendors and other payees through the Automated Clearing House (ACH) system (i.e., direct deposit). For vendors, this service is an efficient alternative to receiving paper check payments.

  • Email Accounts Payable for an enrollment form.

To effectively do business with Cornell, suppliers must register with the university and/or provide the appropriate IRS W-9 or W-8 form. These forms are necessary to ensure the following:

  • Compliance with IRS guidelines
  • Compliance with legal regulations
  • Fulfillment of internal and external reporting requirements
  • Provision of timely payments to our suppliers

If these forms are required, Procurement and Payment Services will email the supplier with either a link to our automated supplier registration tool or paper forms to be completed and returned.

IRS Forms

According to IRS regulations, Cornell University must obtain your correct taxpayer identification number to report income paid to you. Please fax this completed form to the Cornell Procurement Services at (607) 255-9450.

Caution: Do not email scanned copies of W-9 or W-8 forms. Email is not secure. 

IRS.gov offers tax help in a variety of languages. Taxpayers can select their preferred language from the dropdown menu at the top of the IRS home page and access with more than 700 translated forms and publications. See the IRS Languages page for more information.

IRS Form W-9

Use Form W-9 only if you are a U.S. citizen, resident alien, estate, domestic trust, partnership, corporation, company, or association created or organized in the United States or under the laws of the United States.

Note: The IRS has modified this form to include FACTA reporting codes. Please follow the instructions on the form.

IRS Form W-8BEN

For use by individuals (including non-resident aliens) to document your foreign status.

IRS Form W-8BEN-E

For use by entities (e.g., partnership, corporation, company, or association) to document your foreign status.

Please refer to the instructions on the IRS website for help selecting the appropriate W-8 form.
