The Internal Revenue Service (IRS) has released data on individual income taxes for tax year 2019, showing the number of taxpayers, adjusted gross income, income tax paid, and income tax shares by income percentiles. The new data outlines the tax system under the second year of the Tax Cuts and Jobs Act (TCJA), the last year before the onset of the COVID-19 pandemic.
The data demonstrates the U.S. individual income tax continues to be progressive, borne primarily by the highest income earners.
