<prompt> Human: My max contribution limits are:17,500 for Roth 401k5,500 for Roth IRAI know that you can only make a Roth IRA contribution up to your income amount or the contribution limit, whichever is lower. Does this rule apply to the sum of all my Roth account contributions? For example, say that next year, I only make 10,000 post-tax. Can I contribute 100 of my paycheck to my Roth 401k AND 5,500 to my Roth IRA, or must the sum total to all types of Roth accounts not surpass my income for 2015?Thanks in advance for your counsel. :  <response>: You can contribute a maximum of 5500 to an IRA and 18,000 to a 401k in 2015. The limits are separate and independent. That they are both Roth accounts does not matter.
