According to the Office of Management and Budget, in 2015, Americans spent 9.78 billion hours on federal paperwork. The Treasury Department, including the Internal Revenue Service, accounted for the vast majority of the total: 7.36 billion hours. The Department of Health and Human Services was responsible for 696 million hours imposed on (among others) doctors, hospitals, and the beneficiaries of Medicare, Medicaid, and the Affordable Care Act. The Department of Transportation accounted for no less than 214 million hours, including elaborate requirements imposed on truck drivers, automobile companies, railroads, and airlines. Comparatively speaking, the 91 million annual hours that came from the Department of Education might not seem like much, but for administrators, teachers, and students, they were pretty burdensome.
