Q. If I contribute $40,000 to my Roth TSP account, it grows to $60,000 and I subsequently leave government service and roll that Roth TSP into a Roth IRA, wouldn’t I be able to immediately withdraw up to $40,000 without tax or penalty, even though I’m less than 59½ and have not had either account for more than five years?
A. Yes, it is possible to withdraw your contributions at any time without tax or penalty.
