Federal Withholding — Form W-4

Individuals were notified to complete or amend Form W-4 “Employee’s Withholding Allowance Certificate” if they filed “status exemption” allowances. Or if your exempt status has changed since your last W-4 was filed. If you claimed exemption from withholding tax on your year 2018 Form W-4, you must file a new W-4 for year 2019 not later than February 15, 2019, in order to continue to claim exemption in 2019. If you no longer claim exempt status, you must file a new W-4 form.
Unless you file a state Form DE-4, state tax withholding is based on your federal W-4. You may elect to have different federal and state exemption levels or claim state personal estimate withholding allowances by filing both forms. Complete print, sign and submit your form to the Payroll Department.


Advance Earned Income Credit (AEIC)

Based in recent changes to the tax law, the Advance Earned Income Credit has been eliminated, and Form W-5 discontinued effective January 1, 2011. Eligible employees may continue to file for the earned income credit when the complete their individual tax returns. Information for claiming the credit is available in IRS Notice 797 at
