The tax reform law passed at the end of 2017 made massive changes to the way the U.S. government collects taxes. One of its biggest elements affected the way that corporations get taxed, with massive tax cuts for companies of nearly all sizes.
Most of the attention that corporate tax reform has gotten has gone to the largest corporations and the billions in savings they will reap. Yet when you look at the actual marginal rates, the biggest tax rate decline goes to more modestly sized small business with relatively small profits.
