State W-4 Forms


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. (Email is not a secure method to deliver the personal information contained on the W-4).


  • Pennsylvania residents: There are two forms to fill out for your state.
  • Alaska, Florida, New Hampshire, Nevada, South Dakota, Tennessee, Texas, Washington and Wyoming do not collect state income taxes.
