Biden Looks to Raise Tax Revenue When Trump Cuts Expire Next Year

President Biden’s top economic adviser said on Friday that lawmakers should take advantage of a looming tax debate next year to try to reduce budget deficits by sharply raising taxes on corporations and the rich.

Under that plan, Mr. Biden would more than offset the cost of maintaining tax cuts for people earning $400,000 a year or less.

In a speech to the Hamilton Project at the Brookings Institution in Washington, Lael Brainard, who directs the White House National Economic Council, gave the most detailed explanation yet of how Mr. Biden would seek to shape what promises to be a multitrillion-dollar tax debate.

A batch of tax cuts signed into law in 2017 by former President Donald J. Trump, who is facing Mr. Biden in a rematch this fall, is set to expire at the end of next year. It includes cuts for individuals at all income levels. Republicans built that expiration into the tax bill to reduce its projected cost to deficits and comply with congressional rules.

Ms. Brainard’s speech renewed Mr. Biden’s commitment to reducing taxes for middle-class Americans and for raising them on high earners. But her remarks expressed more concern about growing debt and deficits than the president and his aides had previously demonstrated when discussing the looming tax debate.

“At minimum, we should avoid making the fiscal hole created by Republican tax cuts deeper, by fully paying for any tax cuts that are extended,” Ms. Brainard said, in remarks released by the White House. “And we should use the 2025 tax debate as an opportunity to meet our national needs by raising revenue overall by asking the wealthy and large corporations to pay their fair share.”
