Would someone kindly provide information/clarification regarding the Tax percentage that will be applied when I withdraw my entire TSP Balance. I am 66 years old and SINGLE. Based on the fact of being SINGLE, TSP's regulations/rules state I will be taxed as MARRIED with three (3) deductions (children). If that is the case, in a scenario where my TSP Balance is $200,000.00 would I pay 20% in taxes ($40,000.00) and expect to receive a lump sum payment of $160,000.00? Whatever help you can provide will be greatly appreciated!! Thank you ALL.
