Retirement Withdrawals. Since the TSP is a retirement plan, there is no penalty for withdrawing your money during retirement. If you stop working for the federal government, you can start making retirement withdrawals when you turn 55. If you keep working for the federal government, you need to wait until you turn 59-1/2.
DFAS military pay dates (active duty and reserve) are the 1 st and 15 th of every month unless those dates fall on a weekend or holiday. Whenever a payday falls on a weekend or holiday, pay is issued on the last workday preceding the 1st and the 15th. Active duty and reserve members are paid twice a month.
Final Pay: If you entered active or reserve military service before September 8, 1980, your retired pay will be based on your final basic pay. High-3: If you entered active or reserve military service after September 7, 1980, your retired pay base is the average of the highest 36 months of basic pay. If you served less than three years, your base will be the average monthly active duty basic pay during your period of service.
