The Internal Revenue Service (IRS) has redesigned the Employee’s Withholding Certificate, otherwise known as the W-4.  This is the form all employees must complete telling the Exchange how to tax his/her earnings.


The Exchange has implemented the new form, available through Employee Self-Service.  Changing your withholding information is easy.  Log into Employee Self Service at or by clicking on Employee Self-Service under Quick Links on the Exchange intranet home page,


Once logged in, select W-4 Withholding Allowance under Money Matters in the right-hand column. The information requested mirrors the information on the new form.


If you have any issues using the new form, please contact the Human Resources Support Center at or 214-312-6190.  The agents will not help you determine what withholding amount to enter on the form as this is a decision made by you based on your circumstances.



Are all employees required to furnish a new Form W-4?  No. Employees who have furnished Form W-4 in any year before 2020 are not required to furnish a new form merely because of the redesign. Employers will continue to compute withholding based on the information from the employee's most recently furnished Form W-4.

Is there a way to determine how to set my withholding? To provide maximum accuracy, you are encouraged to use the Tax Withholding Estimator available at You should consider using the withholding estimator if you:

•expect to work only part of the year (this does not apply if you are only switching jobs),

•had a large balance due or refund last year and it is no longer the beginning of the current year,

•have dividend or capital gain income or are subject to additional taxes, such as the additional Medicare tax,

•have self-employment income,

•prefer the most accurate withholding for multiple job situations, or

•prefer to limit information provided in Steps 2–4 but do not want to sacrifice accuracy.
