W-4 annual updates
The IRS requires employers to remind their employees annually to review and make any necessary changes to their W-4 (employee's withholding allowance certificate). This review should help you determine if your filing status and/or number of withholding allowances will need to change for the new tax year.
- Review your W-4 tax status in the tax data box on your pay advice or payroll warrant, upper right-hand corner. You can access your pay advice using your campus portal.
- The following IRS resources will help you to determine whether you need to update your W-4 tax information.
Note to international employees: Do not submit a W-4 for 2010. International nonresident employees may only make W-4 changes under the supervision of their campus international tax specialist. Contact an international tax specialist at 303-735-6530 if you believe your status has changed.
The university's Payroll & Benefit Services also has compiled other important annual tax-related reminders for employees, which are available at https://www.cu.edu/pbs/taxreminders.html.
