Q. I’m pretty pleased with the Thrift Savings Plan returns and would like to know if I can deposit any after-tax money into the TSP. If I have a $100,000 in a CD, can I withdraw those funds (and pay the taxes) and deposit them into my current TSP account?
A. No, but you may transfer your 401(k) assets into your TSP account if all of the money in it is taxable upon withdrawal. Use Form TSP-60 and follow the instructions there.
