New York freshman Congresswoman Alexandria Ocasio-Cortezâs mention of a 70% tax on the wealthy provoked heated reaction from both supporters and detractors, with House Republican whip Steve Scalise deriding the idea as a âleftist fantasy program.â
But the debate sparked by the Democrat from New York also revealed some misunderstandings about how Americaâs tax system works.
Marginal vs. average tax rates
On CBSâ â60 Minutesâ Ocasio-Cortez mentioned that historically America has had higher tax rates and that in the 1960s, âonce you get to the tippy tops, on your 10 millionth dollar, sometimes you see tax rates as high as 60% or 70%.â
Though Ocasio-Cortez added that the 70% rate wouldnât apply to all of that income, that detail seemed to get lost in the contentious aftermath. Her comments were widely interpreted as meaning that she wanted the federal government to take 70% of Americansâ income in taxes, a view Scalise broadcast on Twitter
âIf youâre Scrooge McDuck, hedge fund manager, much of your income comes from investments. Itâs coming from long-term capital gains or dividends, which are preferentially taxed.â
But as Ocasio-Cortez clarified in subsequenttweets, her â60 Minutesâ comments referred to the âmarginalâ tax rate.
What does that mean? Hereâs the key distinction: Marginal tax rates are only applied to part of someoneâs income, not to all of their earnings. In other words, someone making $10 million would not lose 70% of that money to taxes under Ocasio-Cortezâs proposal. A 70% marginal tax rate on earnings above $10 million would only apply to the portion of income above $10 million.
For example, if you were getting paid $11 million at your current job, only the last $1 million would be taxed at 70%, said Mark Mazur, director of the Tax Policy Center at the Urban Institute and Brookings Institution. The remainder would be taxed at lower tax rates used for lower incomes.
âItâs important to distinguish between the marginal tax rate and the average rate,â Mazur told MarketWatch.
A householdâs average tax rate â also called their âeffectiveâ tax rate â is the total share of their income that they pay in taxes. Itâs usually much lower than their top marginal rate, as this chart from the Center on Budget and Policy Priorities shows.
Tax brackets vs. tax rates
This is where tax brackets come in. A tax bracket refers to the range of income that gets taxed at a particular rate.
But hereâs another critical point that gets lost in the social-media scrum: Just because youâre âin a 24% tax bracketâ doesnât mean your entire income is taxed at 24%. Under current tax law, if you were a single person, you would only pay that 24% rate in 2019 on income between $84,201 and $168,400.
âIf this 70% tax bracket only applies to earned income, then itâs only going to hit a very small slice of people who earn income above that level.â
Marginal tax rates have fluctuated since income tax was established. The top marginal tax rate peaked at 92% in the early 1950s, according to the Tax Policy Center. In 2019, under the new tax law, the top marginal rate of 37% will apply to income above $510,300 for unmarried individuals, according to the Tax Foundation.
There is more than one way to tax the rich
Ocasio-Cortezâs tax proposal is aimed at the super-rich, but when it comes to taxes, the super-rich are different from you and me, as F. Scott Fitzgerald may or may not have said. (And as MarketWatch reporter Brett Arends pointed out this week, they may also share many of the same qualities.)
Increasing taxes on earned income wouldnât necessarily hit the rich where it hurts the most.
As Mazur noted, when Americans envision a rich person they may think of an NFL player with a $22 million yearly salary. But in reality many of Americaâs wealthy donât accrue their wealth from paychecks, also known as earned income.
âIf youâre Scrooge McDuck, hedge fund manager, much of your income comes from investments,â Mazur said. âItâs coming from long-term capital gains or dividends, which are preferentially taxed.â (Long-term capital gains tax rates, for example, range from 0% to 20% this year.)
âIf this 70% tax bracket only applies to earned income, then itâs only going to hit a very small slice of people who earn income above that level,â said Daniel Bunn, director of global projects at the Tax Foundation.
âOne thing thatâs generally true is that folks that have income of $10 million or more, a lot of their income is what you would call unearned income: capital gains, or benefits from a business that you own or operate, and that may put you in a position where youâre not necessarily taxed at what you might otherwise think based on the top marginal rate,â he added.
Those earning income above $10 million is a much narrower group than the top 1% â it probably amounts to fewer than 0.05% of households, Bunn said.
Who pays the most taxes?
âWhile there are examples of rich people in the United States paying very low average tax rates, our system is â on the whole â average rate progressive,â said Daniel Hemel, an assistant law professor specializing in taxation at the University of Chicago law school. âAverage rate progressiveâ means that average tax rates rise with income.
For 2019, the overall average tax rate (accounting for all types of federal taxes) is 31.1% for families in the top 0.1%, 25.2% for families in the top 10th of income earners, and 18.4% overall, Hemel said, citing Treasury Department data.
The top 1% of income earners paid an average tax rate of 26.9% in 2016, while the bottom 50% of income earners paid an average tax rate of 3.7%, according to IRS data, Bunn said.
