How much income do top-earning households fail to report?
Core argument: The paper estimates that the top 1% of U.S. households fail to report about 21% of their income, with 6 percentage points stemming from sophisticated strategies that random audits do not detect.
Research indicates that the top 1% of households fail to report about 21% of their income, with 6 percentage points attributed to sophisticated strategies undetected by random audits. For the top 0.1%, unreported income may be nearly twice as large as conventional IRS methodologies suggest. This underreporting is largely driven by offshore accounts and pass-through businesses. Internal IRS data revealed that offshore accounts were detected only 7% of the time during random audits. The study assumes noncompliance rates for pass-throughs between those of large corporations and sole proprietorships, leading to higher projections of tax avoidance than previous IRS methods. These findings highlight significant gaps in current IRS detection capabilities and suggest a need for enhanced auditing techniques to address high-income tax evasion.









Ed Comment:“My thinking isn't clear on this but my sense from being on the waters board is that academic research is woefully unproductive relative to commercial research. Yet academies siphone off an enormous amount of talent. So the gov funding more academic research may make the academics more productive in response to the funding than they otherwise would be. But in general, gov funding of academic research makes talented people less productivity because it makes the academies larger than they otherwise would be. Is this a variation of the Simpson paradox?”
