THE U.S. TAX SYSTEM IS PROGRESSIVE
As a whole, the U.S. tax code remains progressive — with higher-income taxpayers paying a greater share of their income in taxes. That is true despite the fact that high-income Americans benefit disproportionately from tax breaks, otherwise known as tax expenditures.
Major tax expenditures — such as lower rates on capital gains and dividends, deductions for charitable contributions, and deductions for state and local taxes — tend to benefit higher-income taxpayers more than lower-income groups. CBO estimates that the top quintile of taxpayers receive 51 percent of the value of major tax expenditures, while only 8 percent goes to the bottom quintile. However, even with substantial tax expenditures, the top one percent of American taxpayers still pay an effective tax rate of 29 percent, on average, while the bottom 20 percent of the population pay an average of 3 percent.
TPC estimates that 68 percent of taxes collected for 2019 came from those in the top quintile, or those earning an income above $163,600 annually. Within this group, the top one percent of income earners — those earning more than $818,700 per year — will contribute over one-quarter of all federal revenues collected.
