"We estimate that 36% of federal income taxes unpaid are owed by the top 1%."
A new analysis by IRS researchers and academics published Monday morning estimates that the richest 1% of U.S. households don't report around 21% of their income, often using complex tax avoidance strategies that allow them to outmaneuver the federal government's increasingly rare audits of the wealthy.
Led by two IRS researchers as well as Daniel Reck of the London School of Economics and Emmanuel Saez of the University of California, Berkeley, the new paper (pdf) finds that 6 percentage points of the richest households' unreported income "correspond to undetected sophisticated evasion" such as offshoring, pass-through businesses, and other avoidance tactics.
"From a policy perspective, our results highlight that there is substantial evasion at the top which requires administrative resources to detect and deter," the authors write. "We estimate that 36% of federal income taxes unpaid are owed by the top 1% and that collecting all unpaid federal income tax from this group would increase federal revenues by about $175 billion annually."
