These questions deal with a 48 year old man, married to a 40 year old lady. I understand that cashing out 401K attracts a penalty of 10% and income tax of 20% if cashed before one is 59.5 yrs. Is this correct? Secondly, if one is short of cash and decides to cash out before they are 59.5 yrs, can they put back in (the 401K) within a specified time, the cashed out amount in order to avoid a penalty? If so, what is the time frame? What does it mean to roll over to an IRA? If you choose to roll over to an IRA, do you pay any penalties? I understand one spouse cannot cash out their 401K without an affidavit (legally documented authorization) from the other spouse. Is this correct? If such is the case and the other spouse actually cashes out without informing the other spouse, what is the legal redress? How can one avoid a penalty when they cash in their 401K?
