The percentage of taxes paid by the highest income earners is lower when you include all taxes, but still pretty significant.[1] These numbers do not include state taxes, only federal.
Income percentile - % individual income tax paid - % all taxes paid
Top 10% - 83.4% - 65%
Top 5% - 69.4% - 53%
Top 0.01% - 26.4% - 19.2%
Note that anyone in the bottom 50% actually has a negative income tax contribution since they get tax credits.
For the top 0.01% of income earners, the average total tax rate is 46.3%. Much higher than I originally thought.
