Information Technology: Cost and Schedule Performance of Selected IRS Investments, Report to Congressional Committees [open pdf - 4MB]
From the Highlights: "IRS [Internal Revenue Service] relies extensively on IT [Information Technology] investments to annually collect more than $3.5 trillion in taxes, distribute more than $450 billion in refunds, and carry out its mission of providing service to America's taxpayers in meeting their tax obligations. For fiscal year 2020, the agency reported spending approximately $2.8 billion for these investments. The Joint Explanatory Statement accompanying the Financial Services and General Government Appropriations Act, 2020 included a provision for GAO [Government Accountability Office] to annually review the status of IRS's IT investments. GAO's specific objectives were to (1) summarize IRS's reported performance for selected IT investments, including CADE [Customer Account Data Engine] 2; (2) identify IRS's reported progress in implementing its 2019 IT modernization plan; and (3) identify the IT-related actions IRS has taken to maximize telework and operate during the COVID-19 [coronavirus disease 2019] pandemic, and any impacts of those actions. GAO obtained IRS's reported performance information for a nonprobability sample of five investments, and compared performance to agency targets. GAO also compared modernization activities that IRS reported completing to those identified in the agency's 2019 IT modernization plan. Further, GAO reviewed agency documentation to identify reported IT actions taken to continue to operate during the pandemic and reported associated impacts. GAO also interviewed cognizant IRS officials."
