What Is The Max I Can Contribute To A Roth 401K? 
That is a great question ! In 2014 you can contribute a maximum of $ 5500 , and if you are over 50 , you can contribute what is called a `` catch up '' amount of $ 1000 , so a total of $ 6500 if you are 50 or older . You must have an income of below $ 114,000 if you are single , and under $ 181,000 if married , and filing jointly . Both you and your spouse can have a Roth , and you both may contribute . The tax code for these things are pretty specific when it comes to earning levels and contributions , so check with your advisor or tax attorney before you contribute , ok ? Thanks for asking !
