Deductions & credits

Yes, that is what i thought as well, but i have a roth 401k and i noticed that my box 1 amt was lower than the box 16,18 amount so i dug further.  What i found was, with Roth 401Ks, the company match is actually into a Traditional 401K. So that is the part that is pre-tax contrib, the company match.  When you have a Roth IRA and company match, you will actually have 2 types of 401Ks, one Roth for your contribs and one trad for the company matches. So i learned something new. Yay.
