Service members serving in a designated combat zone or qualified hazardous duty area, or directly supporting a combat zone can opt in to a savings program that is free, guaranteed and fully backed by the U.S. government. Active duty, Reserve and National Guard members may contribute up to $10,000 to the Savings Deposit Program and earn 10 percent annual interest, compounded quarterly. Moreover, they can leave funds in the program for up to 90 days after redeployment and continue to draw interest. The maximum contribution per month is limited to the individual’s unalloted income, the amount remaining after the collection and payment of all existing taxes, allotments and debt obligations. To establish an account, visit the local finance office with a current Leave and Earnings Statement and make a deposit by cash, check or money order.
