Have effective tax rates on the highest earners risen since 1960?
Core argument: The Auten/Splinter analysis puts the average effective tax rate for the top 0.01% of earners at 47%, counting federal, state, and local taxes, contrary to claims that tax rates on high earners are falling.
The Auten/Splinter analysis reveals that the average effective tax rate for the top 0.01% of earners has increased to 47%, challenging the narrative that tax rates for high-income earners are declining. This comprehensive measure of income and tax burden, which includes federal, state, and local taxes, shows a gradual increase in effective tax rates from 1960 to 2015. Contrary to the Piketty-Saez-Zucman findings, which suggest falling tax rates for the wealthy, the Auten/Splinter data indicate a more progressive tax system over time. Despite recent tax cuts, the long-term trend remains towards increased progressivity, highlighting the importance of data-driven analysis in shaping tax policy debates.





Ed Comment:(note this is the 0.01, not the 0.1)
"...Each frame in Figure 1 below illustrates taxes — federal, state, and local — as a share of income for the highest-earning households from 1960 to 2015. Auten and Splinter’s more comprehensive measure of income and careful measure of the tax burden illustrate that effective tax rates on the top 10 percent, top 1 percent, and even top 0.01 percent of households slowly increased from 1960 to 2015. (The data do not show the tax burdens of the top 400 households, which is the focus of recent research by Saez and Zucman, but the top 0.01 percent of households in the last frame below represents roughly 12 thousand such units)...."
