I have an employee who thinks not enough is getting taken out for Federal Withholding. Right now he has Filing Status of Married, 0 exemptions. I have the 'Use W-4' box checked because that is what I was always told to do. I tested a payroll run and unmarked that 'Use W-4 box' and now more Federal Withholding is being taken out. What is the point of the Use W-4 box if there are no other exemptions being held?
