What happens first is a lot of income restructuring to avoid paying those taxes: https://www.latimes.com/business/la-fi-nocera-tax-avoidance-20190129-story.html https://www.latimes.com/business/la-fi-nocera-tax-avoidance-... I don't think it would really impact startup entrepreneurs much, tax rates at a billion dollars are basically not going to impact anyone: the impact would be on those in the ~100m+ range who will start trying to restructure their investments in a way to avoid the bill. How exactly this would shake out would depend a lot on the exact specifics of what gets written down and are impossible to predict based on a high level description, e.g. few would have predicted an increased investment in oil wells due to the 91% marginal rate before. The only thing people should be sure of is that you will definitely not raise whatever headline number you compute assuming this is a static system that does not adapt.
