Biden Team Prepares $3 Trillion in New Spending for the Economy

Whether it can muster Republican support will depend in large part on how the bill is paid for.

Officials have discussed offsetting some or all of the infrastructure spending by raising taxes on corporations, including increasing the 21 percent corporate income tax rate and a variety of measures to force multinational corporations to pay more tax in the United States on income they earn abroad. That strategy is unlikely to garner Republican votes.

“I don’t think there’s going to be any enthusiasm on our side for a tax increase,” Senator Mitch McConnell of Kentucky, the Republican leader, told reporters last week. He predicted the administration’s infrastructure plan would be a “Trojan horse” for tax increases.

The overall price tag of the package could approach $4 trillion since it includes several tax incentives, like credits to help families afford child care and to encourage energy efficiency in existing buildings. It could also extend temporary tax cuts meant to fight poverty, which could increase the size of the proposal by hundreds of billions of dollars, according to estimates prepared by administration officials.

Mr. Biden supports all of the individual spending and tax proposals under consideration, but it is unclear whether he will back splitting his agenda into pieces, or what legislative strategy he and Democratic leaders will pursue to maximize the chances of pushing the effort through Congress.

His advisers have debated the merits of aggressively pursuing compromise with Republicans and business leaders on an infrastructure package, which would most likely require dropping or scaling back plans to raise taxes on corporations. Another route would be to move the sweeping bill through a special parliamentary process that would require only Democratic votes, as Mr. Biden did with the stimulus package.

“President Biden and his team are considering a range of potential options for how to invest in working families and reform our tax code so it rewards work, not wealth,” said Jen Psaki, the White House press secretary. “Those conversations are ongoing, so any speculation about future economic proposals is premature and not a reflection of the White House’s thinking.”

Mr. Biden said in January that his relief bill would be followed by a “Build Back Better Recovery Plan,” which would include investments in infrastructure, manufacturing, clean energy, skills training and other areas.
