Did it work? In a new paper with my Tax Policy Center colleague Claire Haldeman, we conclude that, consistent with these goals, TCJA reduced marginal effective tax rates (METRs) on new investment and reduced the differences in METRs across asset types, financing methods, and organizational forms.
But it had little impact on business investment through 2019 (where we stopped the analysis, to avoid confounding TCJA effects with those of the COVID-related shutdowns that ensued). Investment growth increased after 2017, but several factors suggest that this was not a reaction to the TCJA’s changes in effective tax rates.
