The Trump administration on Wednesday declared that President Trump would press for the largest tax cut and broadest revamp of the tax system in history, as officials said they would seek huge reductions to 15 percent in the rate paid by businesses large and small.
“We want to move as fast as we can,” Steven T. Mnuchin, the Treasury secretary, said at an event in Washington as the White House planned an afternoon rollout of its principles for what it bills as the first overhaul of the tax code in three decades. “This bill is about creating economic growth and jobs.”
He vowed it would be “the biggest tax cut and the largest tax reform in the history of our country,” in line with Mr. Trump’s grandiose portrayal. But there was no expectation that the White House would elucidate how the deep cuts would be financed, and administration officials are cognizant of the challenges of pushing through a proposal that could dramatically add to the national debt.
