Q. I want to make a one-time partial withdrawal from my TSP account. I realize this withdrawal is subject to the Virginia state and federal income taxes. Who should I contact to learn how much taxes, both federal and state, I have to pay?
A. The withholding requirements are listed in the table on Page 3 of the notice at https://www.tsp.gov/PDF/formspubs/tsp-536.pdf. You won’t know how much tax you’ll actually owe until you file your tax returns for the year, however.
