State W-4 Forms

Purpose

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). Please note: 

• Alaska, Florida, New Hampshire, Nevada, South Dakota, Tennessee, Texas, Washington and Wyoming do not collect state income taxes.
• Residents of Idaho, Indiana, Maine, Minnesota, North Carolina, Oregon: International employees who are classified as nonresident alien taxpayers are subject to restrictions when completing their state W-4 form.  If they have not already, international employees should schedule their required appointment with the International Tax Office to ensure correct withholding.
