W-4 Form
Form W-4 must be completed by each employee in order for the payroll department to determine how much income tax to withhold from each paycheck. It’s important to note that, in accordance with the IRS, if the W-4 is not completed in a timely manner, is completed incorrectly or is altered in any way, the tax withheld must be based on a single filing status with NO allowances.  It is also important for you to know that every time you need to change your dependents, a new W-4 form needs to be sent to Treasury (Payroll Department) to be updated in the system.
