Tim Taylor - most corporate stock is in untaxed hands. Quote:
It used to be that most US corporate stock was held by taxable US investors. Now, most corporate stock is owned by a mixture of tax-deferred retirement accounts and foreign investors. Steven M. Rosenthal and Lydia S. Austin describe the transition in "The Dwindling Taxable Share Of U.S. Corporate Stock," which appeared in Tax Notes (May 16, 2016, pp. 923-934), and is available here at website of the ever-useful Tax Policy Center.
The gray area in the figure below shows the share of total US corporate equity owned by taxable accounts. A half-century ago in the late 1960s, more than 80% of all corporate stock was held in taxable accounts; now, it's around 25%. The blue area shows the share of US corporate stock held by retirement plans,which is now about 35% of the total. The area above the blue line at the top of the figure shows the share of US corporate stock owned by foreign investors, which has now risen to 25%.
Great. So with the corporate tax system shot full of loopholes, and with capital gains essentially untaxed, who's left carrying the entire US tax load?
