"The reported government-wide improper payment estimate for fiscal year 2016 was over $144 billion," the report stated. "This estimate was attributable to 112 programs spread among 22 agencies. Since fiscal year 2003, cumulative estimates have totaled over $1.2 trillion."
The US government is projected to invest more than $89 billion on information technology in fiscal year 2017. The GAO said such expenditures have frequently been futile, expensive and wasteful.
"Historically, these investments have frequently failed, incurred cost overruns and schedule slippages, or contributed little to mission-related outcomes," the report said.
The GAO advised that the government could save billions of dollars and operate more effectively by better managing information technology.
