Q. My question on keeping my money in my TSP when I retire from the Post Office was answered (yes, I can keep it in until age 70 1/2) Now for the next question: If I decide to keep it in the TSP, can I add to it after I retire? I have heard that you can’t, please clarify this. If the answer is no, what would be the advantage of keeping it in? If the answer is yes, how would you do this, automatic from retirement payments?
A. The only way to contribute to your TSP account after you retire is to transfer balances in from other retirement accounts, like an IRA or 401(k) account. It is in your best interest to keep as much of your money in the TSP for as long as possible because of its unique combination of low cost, efficient diversification, ease of management and the availability of the G Fund.
