The Under Secretary of Defense (Comptroller)/ Chief Financial Officer reported that estimated improper payment rates for the DoD Travel Pay program increased from 5.0 percent for FY 2012 to 6.5 percent for FY 2013 and 7.0 percent for 2014.
DoD uses two systems to record DoD travel payments for DoD Components (Military Services and DoD Agencies): the Defense Travel System (DTS) and the Integrated Automated Travel System for Windows. OIG focused on travel payment errors attributed to payments processed through DTS because DTS had the majority of payments and errors reported in the DoD FY 2014 AFR. According to USD(C)/CFO personnel, in FY 2014 DoD paid about $4.7 billion in DTS travel payments, or 72 percent of the total DoD-reported travel payment outlays of $6.5 billion. In addition, USD(C)/CFO personnel estimated that FY 2014 DTS payment errors accounted for $415 million (91 percent) of the total travel payment errors of $458 million.
