As a result of changes made to the federal tax law in December 2017, employers are required to implement new federal income tax withholding tables. These changes will affect the amount of federal tax that is withheld from your paycheck. In most cases, employees will have less federal tax withheld per paycheck.
Employees will see this change implemented in their next paycheck retroactive to the first of the year. They are also encouraged to review their pay data on a regular basis and change their exemptions if needed at any time using Employee Self Service (ESS).
