Improper Payments: Selected Agencies Need Improvements in Their Assessments to Better Determine and Document Risk Susceptibility, Report to Congressional Requesters [open pdf - 4MB]
"Improper payments are a long-standing problem in the federal government, estimated at almost $141 billion for fiscal year 2017. Agencies are required to perform risk assessments to identify programs that may be susceptible to significant improper payments. GAO [Government Accountability Office] was asked to review federal agencies' improper payment risk assessments. This report examines the extent to which certain agencies' improper payment risk assessments for selected programs provided a reasonable basis for determining their susceptibility to significant improper payments. GAO analyzed the most recent risk assessments, from 2015 through 2017, for the following five programs: USDA's [United States Department of Agriculture] Agriculture Risk Coverage and Price Loss Coverage programs; HHS's [Health and Human Services] Head Start; DOJ's [United States Department of Justice] Law Enforcement; and Treasury's Interest on the Public Debt and Home Affordable Modification Program. GAO selected these programs, focusing on programs that recently underwent a risk assessment and size of programs' gross outlays--which totaled about $330 billion in fiscal year 2017 for the five programs GAO selected."
