Employees who are eligible to receive an up-front tax treaty benefit must complete Form 8233—Exemption from Withholding on Compensation for Independent and Certain Dependent Personal Services of a Nonresident Alien Individual.

By completing this form, eligible, nonresident international employees may limit their federal and state income tax withholdings. To establish eligibility for treaty status as well as eligibility for employment, the employee must meet with a CU international tax specialist, and present his/her passport and visa documents for review.

For assistance, contact an international tax specialist at IntlTax@cu.edu.

Departments are encouraged to advise international employees to make an appointment with an international tax specialist via the online appointment scheduling system.
