The House approved the measure by 224-201, passing it for the second time in two days after a procedural foul-up forced another vote on Wednesday. The Republican-led Senate had passed it 51-48 in the early hours of Wednesday.

“We are making America great again,” Trump said, echoing his campaign slogan at a White House celebration with Republican lawmakers. “Ultimately what does it mean? It means jobs, jobs, jobs, jobs.”

Trump, who emphasized a tax cut for middle-class Americans during his 2016 campaign, said at an earlier Cabinet meeting that lowering the corporate tax rate to 21 percent from 35 percent was “probably the biggest factor in this plan.”

It was uncertain when the bill would be signed. White House economic adviser Gary Cohn said the timing depended on whether automatic spending cuts triggered by the legislation could be waived.

The administration expects the waiver to be included in a spending resolution Congress will pass later this week, a White House official told reporters. Cohn told Fox News Channel on Wednesday night that Trump could sign the bill as soon as Friday if the resolution was passed by then.

In addition to cutting the U.S. corporate income tax rate, the debt-financed legislation gives other business owners a new 20 percent deduction on business income and reshapes how the government taxes multinational corporations along the lines that the country’s largest businesses have recommended for years.

Wall Street’s main indexes were little changed on Wednesday, taking a breather after a month-long rally ahead of the long-anticipated tax vote. The S&P 500 has climbed about 4.5 percent since mid-November, led by a rally in sectors such as transport, banks and others that are expected to benefit the most from lower taxes.

Under the bill, millions of Americans would stop itemizing deductions, putting tax breaks that incentivize home ownership and charitable donations out of their reach, but also making tax returns somewhat simpler and shorter.

The bill keeps the existing number of tax brackets but adjusts many of the rates and income levels for each one. The top tax rate for high earners is reduced. The estate tax on inheritances is changed so far fewer people will pay.

Once signed, taxpayers likely would see the first changes to their paycheck tax withholdings in February. Most households will not see the full effect of the tax plan on their income until they file their 2018 taxes in early 2019.

In two provisions added to secure needed Republican votes, the legislation also allows oil drilling in Alaska’s Arctic National Wildlife Refuge and removes a tax penalty under the Obamacare health law for Americans who do not obtain health insurance.

Democrats were united in opposition to the tax legislation, calling it a giveaway to the wealthy that will widen the income gap between rich and poor, while adding $1.5 trillion over the next decade to the $20 trillion national debt. Trump promised during the campaign that he would eliminate the national debt.
