Q. I recently retired under CSRS. I am 57. I would like to take a partial withdrawal from my TSP. What penalties and taxes will I have to pay on the amount I withdraw.
A. As long as you retired during or after the year in which you reached age 55, there will be no early withdrawal penalty due. There will be 20 percent mandatory withholding taken from your payment, however, unless you roll the money over directly to an IRA.
