A strong economy means more Americans are earning $400K. What's it mean for their taxes?

During the 2020 presidential campaign, candidate Joe Biden presented voters with a bold pledge: He wouldn’t raise taxes on anyone earning less than $400,000.

President Biden has carried the same promise, and the same round sum, into his reelection campaign in 2024. If your income falls short of $400,000, you’re immune to tax hikes. If you earn more than that, your taxes may go up, and you just might be audited by the IRS.

But a lot more people make $400,000 now than in 2020.

Between 2019 and 2023, the number of American households earning more than $400,000 swelled by nearly half, from 2.6 million to an estimated 3.8 million out of roughly 131 million households. The figures come from census data compiled by the Economic Innovation Group, a public policy think tank based in Washington, D.C.

Earnings are up for most Americans, both because of a strong economy and in response to rising consumer prices. Average hourly wages rose by more than one-fifth between January 2020 and April 2024, from $28.44 to $34.75, federal data show.

President Joe Biden announced plans to tax corporations and those making over $400,000, in an effort to lower the country's financial deficit during a speech in New Hampshire.

$400,000 doesn't have the same buying power in 2024

And $400,000 doesn’t have the same buying power. If you adjust the figure for inflation, a $400,000 salary in January 2020 would be worth about $486,000 now.

“Back then, $400,000 was a more notable number,” said Jonathan Swanburg, a certified financial planner in Houston.

Perhaps it is too much to ask a candidate to apply a cost-of-living adjustment to a pithy campaign pledge. If Biden hit the trail in 2024 promising not to raise taxes on anyone earning less than $486,000, voters might react with puzzlement.

And therein, some economists say, lies one of several problems with invoking an arbitrary figure when setting fiscal policy.

“I think it’s kind of a ridiculous line to draw in the first place,” said Michael Strain, director of economic policy studies at the American Enterprise Institute, another Washington think tank.

“The threshold is not indexed to inflation, and it’s not indexed to average growth,” Strain said. “So, over time, more and more households are going to get hit by it.”

Biden administration officials say the $400,000 pledge was meant to signal his commitment not to raise taxes on anyone but the rich and his quest to ensure that the very rich don’t cheat on their taxes.

“President Biden’s pledge not to raise taxes on anyone making less than $400,000 is a clear, direct and easy-to-understand commitment to the American people that, as long as he is president, he will not raise taxes on the middle class by one penny," said Jeremy M. Edwards, a White House spokesperson, adding that the president "will instead fight for a tax system that finally asks the wealthiest Americans and largest corporations to pay their fair share”
