Retirement tax questions

Check boxes 3 & 4.  How much is in each box?  Box 4 should be Box 3 x .062 up to a max of 8,853.60.   If box 4 is more than that you need to get a corrected W2 from your employer.  Try leaving the cents off box 4.  But also go back and double check your W2 entries, you may have entered box 3 & 4 wrong.  A lot of people who have asked this found they did enter an amount wrong.
