Representative Carlos Curbelo, a member of the panel, said there “may be some” differences in the legislative text by the time the committee begins its work. “It’s settling; it’s all settling,” he said. Details began to emerge late Wednesday.

The child tax credit would be increased to $1,600 from $1,000 per child under 17, with an additional $300 credit for each parent as part of a consolidated family tax credit, according to the House memo. The credit had been a priority for Ivanka Trump, who had met with lawmakers in recent weeks to discuss it.

One key consideration involves a compromise that Brady offered on tax breaks for individuals in high-tax states: allowing individuals to deduct the cost of their state and local property taxes. That benefit would be capped at $10,000, according to the memo.

‘One by One’

It was unclear Wednesday how many lawmakers would be won over by Brady’s offer to preserve an individual deduction for state and local property taxes. “They’re working over concerned lawmakers one-by-one at this point,” Representative Tom MacArthur, a New Jersey Republican, said of GOP leaders.

“We are close,” said Representative Tom Reed of New York Wednesday evening. “We are going to be able to solve that problem.”

Members of the Ways and Means panel met late into the night Wednesday as they discussed yet another issue: placing limits on a proposed tax cut for many businesses organized as partnerships, limited liability companies and other so-called pass-throughs. Currently, such companies pass their earnings through to their owners, who are taxed at their individual income rates -- which can be as high as 39.6 percent.

The bill would reduce the top rate to 25 percent -- but place limits on the kind of income that would qualify, said a person aware of the details. First, “professional services” -- including doctors, lawyers, accountants and others -- wouldn’t qualify for the rate.

Other business owners could chose one of two options: 1. Categorize 70 percent of their income as wages -- and pay their individual tax rate on it -- and 30 percent as business income, taxable at the 25 percent rate. Or 2. Set the ratio of their wage income to business income based on the level of their capital investment.

The guidelines are aimed at preventing abuse of the 25 percent rate -- such as high-earning individuals forming themselves into corporations to get a tax cut.
