It is time for employees to review their current withholding certificates, IRS form W-4 and IL-W-4. Withholding is the amount of federal and state income tax an employer pays on behalf of an employee. Consider completing a new withholding certificate form each year and when your personal or financial situations change so Illinois State University can withhold the correct amount from your pay. For further guidance, refer to the IRS video, Do I Need to Fill Out a New W-4?

To review and/or change your withholdings:

  • Login to iPeople.
  • Select Tax Forms.
  • Review the Tax Withholding: Fed W4, State section for the federal and state form types.
  • To make changes, follow the written instructions or the video tutorial.
    • You will not be able to complete this process if you are a nonresident for tax purposes in the United States or if you have an IRS Lock-In Letter on your account.

What if I need assistance calculating my withholdings?

Illinois State University is not able to provide guidance on completion of the Form W-4. Visit the IRS Tax Withholding Estimator and the IRS Tax Withholding informational site for additional information. The IRS Withholding Estimator is updated annually; visit the website in January to plan for 2024. For further assistance, contact a tax professional.

What if I claimed tax-exempt status?

To continue claiming an exemption for the new year, employees who claimed total exemption from income tax withholding in 2023 must submit a new Form W-4 for the year 2024 by February 15, 2024. If the new form is not submitted by February 15, the University must begin withholding.

What if I’m not a United States citizen?

Employees present on a visa status may submit a new Form W-4 or make changes to an existing Form W-4 using the Sprintax Calculus software. If you do not yet have a profile or need assistance accessing your profile, contact TaxOffice@IllinoisState.edu. You may also schedule an in-person or virtual appointment with an ISU tax specialist through Calendly.
