Critics say the tax would be difficult for the federal government to calculate and enforce, that it would discourage investment and that it could be ruled unconstitutional by courts. Ms. Warren has amassed letters of support from constitutional scholars who say the plan would pass muster.
Ms. Warren estimated her initial proposal during the 2020 campaign would raise $2.75 trillion over a decade, which she proposed spending on education and child care, based on estimates from the University of California, Berkeley economists Emmanuel Saez and Gabriel Zucman.
The latest version, which would begin to apply in 2023 to net worth as calculated in 2022, would raise $3 trillion, Mr. Saez and Mr. Zucman calculate. Other economists, including Natasha Sarin of the University of Pennsylvania and Lawrence H. Summers of Harvard, estimate the tax would raise significantly less.
Mr. Zucman and Mr. Saez say the increase in their estimate is partly the product of a pandemic recession and recovery, which has enriched some of the wealthiest Americans and exacerbate wealth inequality.
“Wealth at the top, particularly among billionaires, has grown in the two years” since the 2019 estimate of Ms. Warren’s plan, Mr. Saez and Mr. Zucman write in a new estimate accompanying the bill.
In an email, Mr. Zucman noted that “the disconnect between wealth growth for the ultrawealthy and wealth growth for most Americans is not a new phenomenon: Billionaire wealth has been growing faster than the economy for the last 40 years.”
“But,” he said, “this disconnect has widened during the pandemic. The upshot is that a wealth tax could be a significant source of government revenue in the years ahead.”
The White House press secretary, Jen Psaki, did not answer directly on Monday when asked at a briefing if Mr. Biden supported Ms. Warren’s proposal. “The president strongly believes that the ultrawealthy and corporations need to start paying their fair share,” she said.
