Background: Most folks are familiar with RMDs. RMDs are required from IRAs, but not from 401Ks, so long as the 401K participant is still "employed" by the employer providing the 401K. OK, that's easy. Here's the head-scratcher.
Hypothetical: Jane is employed by XYZ company and has a 401K plan. Her vested balance is bigger than a bread-box, she's turned 70 1/2 this year, and she really doesn't want to start taking RMDs from her 401K anytime soon. Her tax advisor (and the HR folks) advise her she need not take RMDs from her 401K until the year she retires. Jane wants to throttle back, but not retire. XYZ is more than wiling to let Jane go seriously "part-time", say to 10 hours/week, and still consider her a part-time employee, and participate in the 401K.
The head-scratcher: Will the IRS still consider Jane an "employee" for purposes of the 401K and not be required to start RMDs? Clearly, were Jane to retire, her RMDs on the 401K would kick in immediately. But if Jane only "semi-retires" and is still an employee, can she continue to defer RMD withdrawals indefinitely? Everything I've read points to "yes". Stated another way, part-time employees are still "employees", and there appears to be no minimum hourly threshold.
Conundrum: Clearly, the IRS wants to get its deferred tax from IRAs and 401Ks. If 401K participants can stretch out the process by staying "employed" (even as part-timers), does not this strike one as odd?
