Over the by few decades, at that topographic point has been an amazing shift inward how businesses are taxed. See the figure below, which is from CBO. Businesses are to a greater extent than in addition to to a greater extent than taxed every bit pass-through entities, where the income shows upwards on personal revenue enhancement returns rather than on corporate returns. (Here is an article discussing how the usual giant Fidelity late switched from 1 shape to the other.)

This phenomenon complicates the interpretation of revenue enhancement furnish data. For example, when 1 looks at the increase of the 1 percent, or the 0.1 percent, inward the Piketty-Saez data, that increase is probable exaggerated because roughly income is simply beingness shifted from corporate returns. I don't know how much. If someone has already quantified the magnitude of this effect, delight electronic mail me the answer. If not, someone should write that paper.
