I have two daughters both work at restaurants. W-2's for both have wages in box 3 significantly lower than wages in boxes 1 and 5. Social security tax calculated on wages in box 1 not box 3. Turbotax indicated employer over withheld in one case but not the other. Question: Why are wages on box 3 less than boxes 1 and 5. They do not have 401k's.
