NEW YORK — Republican presidential front-runner Donald Trump, as part of a plan he said Monday would grow the U.S. economy at a pace not seen in years, proposed eliminating income taxes for millions of Americans and lowering rates for the highest-income earners.

Trump’s plan for an overhaul of the U.S. tax code would eliminate federal income taxes on individuals earning less than $25,000 and married couples earning less than $50,000.

Trump’s plan also would benefit wealthy earners, by lowering the highest income tax rate from 39.6 percent to 25 percent. It would help businesses — from major corporations to mom-and-pop shops — by cutting the tax rate to no more than 15 percent.

“There will be a major tax reduction,” Trump said in Manhattan. “It’ll simplify the tax code.”

Trump said he wants to eliminate the “carried interest loophole,” which allows managers of hedge funds and private equity firms to pay a lower tax rate than most individuals, and would reduce or eliminate most deductions and loopholes for individuals and corporations. “In other words, it’s going to cost me a fortune,” he said.

The billionaire real estate mogul said those changes would pay for the tax cuts.

Jared Bernstein, former chief economist for Vice President Joe Biden, said before Trump’s news conference there were “a couple of inherent problems” with Trump’s plan. He pointed out that about 40 percent of Americans are exempt from paying federal income taxes and the tax burden on the middle class “comes from other places.”

“Lowering payroll taxes, that’s one thing. But then you have a Social Security funding problem,” Bernstein said.

• Former Florida Gov. Jeb Bush suggested three (slightly higher) tax

brackets this month. The cuts

would cost an estimated $3.4 trillion

over a decade, with a net revenue loss

of $1.2 trillion after projected

economic growth.

• U.S. Sen. Marco Rubio has proposed abolishing the alternative minimum

tax and ending all deductions, save

those on charitable giving and

mortgage interest. The plan to slash

taxes on investments, wages and

business income would reduce

collections by $1.7 trillion during the

same time while, like Bush, largely

favoring the top 1 percent.
