Can I Cash Out My Roth 401K? 
Because your Roth 401k contributions were from after-tax dollars , you can withdraw your contributions to the account without facing penalties or taxes . Withdrawals beyond the level of your contributions , can result in a penalty and taxes if you are under 59 1/2 and have not had the account for a minimum of 5 years . There are some hardship exceptions to the age rule .
