In U-turn, Trump says he expects to raise taxes on rich

Donald Trump signaled in remarks broadcast Sunday that he would consider raising taxes on wealthy Americans, and that his tax plan unveiled so far was not set in stone.

Asked on ABC's "This Week" to clarify his stance on taxation, the presumptive Republican nominee said he did not expect his proposals for cutting taxes across the board to make it intact through the US Congress.

"By the time it gets negotiated, it's going to be a different plan," Trump said. "And in my opinion the taxes for the rich will go up somewhat."

"I am willing to pay more. And do you know what? The wealthy are willing to pay more," he added.

Trump's tax plan -- his most detailed policy proposal so far -- vows to eliminate taxes for half of all households, and slash taxes for the middle and upper classes, while closing beneficial loopholes for the very wealthiest.

"The thing I'm going to do is make sure the middle class gets good tax breaks," Trump said.

"The other thing, I'm going to fight very hard for business. For the wealthy, I think frankly it's going to go up.

"You know what, it really should go up."

The main focus of Trump's tax plan unveiled last September is on reducing business income tax to a flat rate of 15 percent.

Under the plan, some 50 percent of US households would pay no federal income tax because they earned less than $50,000 -- up from 43 percent who paid no tax in 2013 according to the Tax Policy Center.

Under a simplified tax code, the three other brackets would be 10 percent, 20 percent, and 25 percent, the latter for households with income of $300,000 or more.

The current top bracket is 39.6 percent for individuals making more than $413,000.
