Did you claim tax exempt status in 2019?
All employees who claimed total exemption from income tax withholding in 2019 must submit a new 2020 Form W-4 by February 18, 2020, to continue to claim exemption from withholding in the new year. After that date, Illinois State must begin withholding income tax if the 2020 Form W-4 is not submitted.

W-4 requirements for Non-US Citizen Employees
Non-U.S. Citizen Employees must not fill out a new W-4 or make changes to an existing W-4 without guidance from a tax specialist in the University Payroll Office.  If applicable, treaty benefits need to be renewed each calendar year.  Please contact the University Tax Specialist by call (309) 438-3106 or e-mail to schedule an appointment.
