Q. I fell under FERS disability. What percentage will I be hit with on a full withdrawal of my TSP? I am under the 55 age limit.
A. The withholding for federal taxes will be 20 percent. The tax and early withdrawal penalty you actually owe on the withdrawal will be calculated when you file your tax return for the year. Unless you qualify for one of the exceptions listed on the left side of Page 7 of the notice at https://www.tsp.gov/PDF/formspubs/tsp-536.pdf, in addition to income taxes, your withdrawal will be subject to the 10 percent early withdrawal penalty.
