High-Income Tax Avoidance Far Larger Than Thought, New Paper Estimates
The top sliver of high-income Americans dodge significantly more in income taxes than the Internal Revenue Service’s methods had previously assumed, according to forthcoming estimates from IRS researchers and academic economists.
Overall, the paper estimates that the top 1% of households fail to report about 21% of their income, with 6 percentage points of that due to sophisticated strategies that random audits don’t detect. For the top 0.1%, unreported income may be nearly twice as large as conventional IRS methodologies would suggest, the researchers wrote.
