Only uniformed services can make employee after-tax contributions and then only from tax exempt pay while deployed in a combat zone.
These special employee after-tax contributions are not eligible for in-service rollovers and the TSP does not support in-plan Roth Rollovers (IRRs) that would enable the Mega Backdoor Roth.
However, if they only occur a limited time before separation, there may not be ecessive pre-tax earnings on the employee after-tax contributions when they and the earnings are rolled over.
