Isn't it true that, even if you wanted to contribute "after-tax" money to a 401k, you would still bump up against the limits?
Not sure about that, I give right to the limit (remember mine is a govt 401K we call a TSP so it may be a little different in some details) when I reach the limit they just cut me off (I also lose the employer matching $$ for however many pay periods are left too).
Or are you talking about income limits? As far as I know there are no income limits to 401Ks, only with the Roth.
