Reporting Roth Solo 401k Distributions

First available in 2006,  the number of participants eligible to take distributions from Roth 401k designated accounts through their employers or Roth solo 401k plans for those who are self-employed has been minimal but will begin to pick in the coming years.

Designated Roth account assets must satisfy the distribution requirements applicable to elective deferrals (i.e., employee contributions) under the plan. For example, Roth solo 401k contributions are fully vested, are subject to required minimum distributions (RMDs), and cannot be distributed until the solo 401k participant meets a distribution triggering event under the plan (e.g., termination of employment, death, disability).

When a 401k or solo 401k plan participant takes a distribution from a designated Roth account, the participant must review a 402(f) notice, which outlines the tax and rollover options available upon plan distribution.
