My company plan permits after-tax conversion to the plan Roth 401K. The after tax contributions have been sitting in the plan for 5 years and have earnings. My questions are:
1- When I convert a portion of the after tax money to Roth 401K, will it force me to also convert a portion of the earnings?
2- If yes, who determines that earnings portion and how it is reported to me next year so I pay the corresponding ordinary income taxes in my tax return?
