The effort they are calling “Phase 2” appears to unify two lingering problems from the tax cut bill that Republicans sped through Congress late last year. In both cases, fixing them would require support from Senate Democrats, who are not inclined to lend any backing to a tax bill that they opposed and that was passed over their objections.
One problem is that tax cuts for individuals are set to expire at the end of 2025. That is a byproduct of the budget reconciliation process that Republicans employed to pass the bill without Democratic support. To comply with rules against increasing budget deficits after 10 years, Republicans made the individual cuts temporary.
Mr. Brady alluded to that on Wednesday. “While the tax cuts for families were long term, they’re not yet permanent,” he said. “So we’re going to address issues like that, and we’re in discussions with the White House, with the president about this issue.”
A second issue, which Mr. Brady also addressed, is the host of legislative ambiguities and hiccups that companies and accountants have discovered in the law since it was passed. Those include the so-called grain glitch, which inadvertently gave an advantage to agricultural cooperatives over other, independent businesses that farmers might sell to, and a provision that diminishes the tax benefits from renovating restaurants.
Senate leaders have discussed fixing the grain glitch in a coming spending bill. But a Republican Senate aide said there was little optimism for Congress pushing another stand-alone tax package this year.
Mr. Trump’s interest in repeating his tax cut success may not be surprising given the validation he received at the Boeing plant here. Bonnie Brazzeal, who works in the cafeteria at the College of the Ozarks, choked up when she told the president that she received a bonus from her employer as a result of the tax cut.
“I am very grateful for the bonus when the college gave it to us,” Ms. Brazzeal said. “I put mine in my savings for retirement.” She then wiped away tears.
Dennis A. Muilenburg, Boeing’s chief executive, attributed the company’s strong performance to Mr. Trump. “What you see is your leadership on tax reform and creating jobs,” Mr. Muilenburg said. “There’s no place that’s more evident than the factories of America, and you can see it here.”
Mr. Trump said that when it came to the economy, there was more to come. “I don’t see any downward movement,” he said. “I see just up.”
