Deductions & credits

@sasho1987   Why are you trying to figure out the boxes?  Don't you have your W2?  There are several things that are pre-tax and aren't included in box 1 but maybe in box 3 & 5.  I never could figure out my W2 boxes.  My paystubs never matched my W2.   If you don't understand something on your W2 you have to ask your employer.  You should not be making up the W2 entries.
