I know this argument runs against the mood affiliation of our times, but the arguments for eliminating the corporate income tax still seem pretty good to me. Here is a recent paper by Hans Fehr, Sabine Jokisch, Ashwin Kambhampati, and Laurence J. Kotlikoff. The abstract runs as follows:
We simulate corporate tax reform in a single good, five-region (U.S., Europe, Japan, China, India) model, featuring skilled and unskilled labor, detailed region-specific demographics and fiscal policies. Eliminating the model’s U.S. corporate income tax produces rapid and dramatic increases in the model’s level of U.S. investment, output, and real wages, making the tax cut self-financing to a significant extent. Somewhat smaller gains arise from revenue-neutral base broadening, specifically cutting the corporate tax rate to 9 percent and eliminating tax loop-holes.
