Congress has signed off on a $3.4 trillion legislative package featuring new tax breaks, spending cuts, and more funding for defense and immigration enforcement, delivering President Donald Trump his “big, beautiful bill” despite rumblings from fiscal hawks about the projected $4 trillion it could add to the national debt over the next decade.

The bill modestly and permanently raises the maximum amount of the child tax credit from $2,000 to $2,200 per child under the age of 17 and requires at least one parent to have a Social Security number. Those with lower incomes will not benefit as much because they make too little and the tax credit is not fully refundable.
