Book Description
Improper payments are a long-standing, significant problem in the federal government, estimated at nearly $137 billion in fiscal year 2015. GAO previously reported that one strategy to help prevent improper payments is up-front verification of eligibility through data sharing and matching. Established by OMB in 2011 and hosted by Treasury, the DNP working system is a web-based, centralized data matching service. GAO was asked to review the DNP working system. This report examines the extent to which (1) OMB and Treasury developed the DNP working system and obtained access to relevant databases, (2) selected agencies used the DNP working system to help review eligibility, and (3) OMB monitored the use of the system. GAO reviewed relevant laws and guidance; interviewed officials at OMB, Treasury, and 10 user agencies selected in part based on size and reported improper payment estimates, including those with the largest reported estimates; and analyzed DNP working system documentation.
