Q. I will retire Jan. 2 in CSRS. I believe the paydays on Jan. 2 and Jan. 16 will be part of the 2015 TSP contribution year. Also, I believe that I can contribute up to 100 percent of my basic pay to TSP (which is what I would like to do for these last two pays). Would the 100 percent be whatever is left after all other deductions (taxes, FEHB, etc.) have already been deducted? Essentially, when does the 100 percent get applied?
A. The 100 percent is applied after all required deductions have been subtracted.
