All persons receiving tax reportable payments from UW-Madison must have, or have applied for (proof required), a United States Taxpayer Identification Number (TIN). For individuals the Taxpayer Identification number can be a Social Security Number (SSN) or an Individual Taxpayer Identification Number (ITIN). For businesses the Taxpayer Identification Number is an Employer Identification Number (EIN) or a Federal Employer Identification Number (FEIN).
The flowchart below outlines the requirements for obtaining or applying for a Social Security Number (SSN) or an Individual Taxpayer Identification Number (ITIN) for all Nonresident Aliens (NRA’s) that are being paid through the University of Wisconsin.
As stated in the flowchart, please make sure that if your nonresident alien visitor needs an SSN or an ITIN that you plan ahead of their visit and schedule appointments ahead of time to have them apply for their numbers. The University of Wisconsin ITIN Acceptance Agent requires appointments for all ITIN applications. Please do not send your foreign visitors or students to the University of Wisconsin ITIN Acceptance Agent without appointments.
