I am currently a full time college student/SAHM, but my hubby has a 401K through his employer. The 401k company website (John Hancock) states that we can contribute up to 60% of his salary. I know the 2015 IRS max is somewhere in the ballpark of $18,000. So can we contribute OVER $18000 as long as we don't contribute over 60% of the salary? I'm confused.
