<prompt> Human: Now I know what a ROTH account is, and what it means. However, I am not sure what it means when it comes to the 401k Options. I currently elect to contribute 6 pretax, and 2 ROTH on my Fidelity 401k. I just started contributing to the Roth on my 401k Account. it shows as other on my sources list other are employee contribution, company match, supplemental, etc I have a personal Roth IRA that I max out. so my questions are, 1 does the ROTH 401k option have any impact on my personal ROTHsuch as max contribution? and 2 does the 401k ROTH allow me to contribute up to 18K obviously taxed at contribution?Image of the contribution options I have on fidelity.  <response>: I dont know why this misconception is so common. A 401k is through your employer, and an IRA is not through your employer. Both 401ks and IRAs can either be traditional or Roth. 401kIRA is the noun, traditionalRoth is the adjective. Yet everyone calls their Roth IRA their ROTH. I could speculate on why, but that would just add to the confusion.
