Washington: President Donald Trump’s tax-cut package cleared its final hurdle in the US Congress on Thursday, as the Republican-controlled House of Representatives narrowly approved the massive bill and sent it to him to sign into law.

The 218-214 vote amounts to a significant victory for the Republican president that will fund his immigration crackdown, make his 2017 tax cuts permanent and deliver new tax breaks that he promised during his 2024 campaign.

It also cuts health and food safety net programs and zeroes out dozens of green energy incentives. It would add $US3.4 trillion ($5.2 trillion) to the nation’s $US36.2 trillion debt, according to the nonpartisan Congressional Budget Office.

The White House sad Trump planned to sign the so-called “big beautiful bill” on Friday at 5pm Washington time (7am Saturday AEST).

Despite concerns over the 869-page bill’s price tag and its hit to healthcare programs, Republicans largely lined up in support, with only two of the House’s 220 Republicans voting against it. The bill has already cleared the Republican-controlled Senate by the narrowest possible margin.

Republicans said the legislation will lower taxes for Americans across the income spectrum and spur economic growth.

Republican representative Virginia Foxx of North Carolina described the bill as bringing “historic tax relief for working families. Massive investment to secure our nation’s borders. Capturing generational savings. Slashing waste, fraud and abuse in government programs so that they may run more efficiently”.

Every Democrat in Congress voted against it, blasting the bill as a giveaway to the wealthy that would leave millions uninsured.
