IRS Is Scaling Back Activities and Using Budget Flexibilities to Absorb Funding Cuts, GAO-15-624: Published: Jun 24, 2015. Publicly Released: Jul 24, 2015: “Internal Revenue Service (IRS) total appropriations declined from a high of $12.1 billion in fiscal year 2010 to $11.3 billion in fiscal year 2014, a reduction of about 7 percent. GAO selected business units with large declines in obligations—both dollar amount and percent—from fiscal year 2010 to fiscal year 2014, the most current spending data available. To absorb budget cuts, the business units GAO reviewed—Human Capital Office, Office of Chief Counsel, and Small Business/Self-Employed Division—each reduced staff (full-time equivalents or FTEs) by 16 to 30 percent. According to officials, they also prioritized legally required programs, such as tax litigation, and reduced some programs or services, such as limiting non-filer investigations, postponing software acquisitions, and delaying approximately 24,000 employee background reinvestigations. Such scaled back activities potentially reduce program effectiveness or increase risk to IRS and the federal government.”
