“Despite ProPublica‘s best efforts to make the information enclosed within seem damning, the data tell us little we didn’t already know. For the 2018 tax year, the last year for which we have data, the top 1 percent paid over 40 percent of federal income taxes, despite earning just under 21 percent of total adjusted gross income (AGI). The bottom 50 percent of taxpayers earned 11.6 percent of total AGI, but paid less than 3 percent of income taxes. The same story holds when looking at all revenue sources too, so it’s not just the income tax that is progressive.
ProPublica, however, tries to make the case that the wealthy are getting away with murder through the tax code, so they “do a calculation that has never been done before,” comparing growth in wealth over the course of a year to taxable income. They use this to calculate an individual’s “true tax rate,” which is sort of like handing out wins in a baseball game in the middle of the early innings and calling it the “true outcome” of the contest.
It’s hard to overstate how nonsensical this comparison is (which is perhaps why it’s never been done before). Our tax system rightly does not tax growth in one’s wealth until it is realized as income. After all, the alternative is a monstrously complex and unfair system of wealth taxation that developed countries have avoided.
The reason that wealth isn’t taxable is fairly straightforward: You aren’t directly benefiting from it until it’s turned into income (at which point it is taxable). Wealthy Americans may not pay taxes on the growth that their net worth sees, but should they wish to sell assets that have appreciated in value, they would be liable for capital gains taxes on that growth.”
