This is the form you fill out and give to your employer when you want to change how much federal taxes are taken out of your paycheck.  A higher number in box 5 means less taxes will be taken from your check.”

EDD DE-4

Most employers just use the W-4 above to estimate your state taxes.  But you can adjust state taxes separately.  This is the form you fill out and give to your employer when you want to change how much states taxes are taken out of your paycheck.  A higher number in box 1 means less taxes will be taken from your check.”
