State W-4 Forms

Last updated: 2018


The University of Colorado withholds state taxes from the state in which you perform work. All out-of-state employees must fill out a W-4 for the state in which they work and mail or fax it to Employee Services. (Note: Email is not a secure method to deliver the personal information contained on the W-4).
