2020 Tax Information

The Internal Revenue Service (IRS) issued a new federal W-4 for the 2020 tax year. The new federal W-4, designed in alignment with the 2018 tax reform bill (The Tax Cuts and Jobs Act), no longer uses withholding allowances.

Special note: The state of South Carolina has also issued a new tax chart and a new SC W-4. We are manually updating the SC tax chart to apply to the January 15 paycheck, however, we are still awaiting a tax update from PeopleSoft before the new SC W-4 is available online. When the new SC W-4 is available, we will issue a separate communication and any pertinent guidance.

What this means for you

You are encouraged to reassess your tax situation and submit a new federal W-4 for the 2020 tax year. You are not required to submit a new federal Form W-4. If you do not furnish a new federal Form W-4, your tax withholding will continue based on the information on your existing federal W-4; however, the withholding will be based on the new 2020 federal tax chart, which means actual federal tax withheld may change. Note that special rules apply to federal Forms W-4 claiming exemption from withholding. 

The IRS has developed Frequently Asked Questions (FAQs) regarding the new federal W-4. 

The IRS has developed a Withholding Estimator to help you estimate your 2020 tax liability. View the quick reference guide below for step-by-step instructions on how to fill out the Withholding Estimator using information from your Clemson University paystub. (The PeopleSoft Employee Self Service Paycheck Modeler is currently out of service. We have contacted the software vendor and are awaiting feedback regarding a fix.)

Use the button below to access the quick reference guide for using the IRS Withholding Estimator. At the end of the IRS Withholding Estimator, you may be prompted to download and print a pre-filled federal W-4. Instead of manually submitting the pre-filled federal W-4, you should submit any changes online using the “Begin New Federal W-4” button below.
