Republican Sen. Ron Johnson says he has cut a deal with Senate leadership and is prepared to cast the deciding 50th vote to pass the GOP tax overhaul bill.
Johnson said Friday on the "Jay Weber Show" on WISN-AM in Milwaukee that he secured changes in the bill on taxes paid by pass-through businesses that helped win his support. He says there will also be better transition rules for companies that are reorganizing.
At issue were millions of businesses whose owners report the firm's profits on their individual tax returns. The vast majority of U.S. businesses are taxed this way.
Johnson says the deal also gives him a role in the process of reconciling the Senate and House versions of the bill.
"I sought assurance and I was given assurance that I will be at the table" when Senate-House bargainers write a compromise version of the bill, Johnson said of talks he had with GOP leaders Thursday night.
Johnson's support for the legislation is a major boost for Majority Leader Mitch McConnell as he tries to muscle the measure through the Senate.
A Senate Republican leader claimed enough votes Friday to push the party's $1.4 trillion tax bill through the chamber, apparently overcoming eleventh-hour hitches that had raised questions about whether the GOP's push for its highest legislative priority might falter.
"We're confident in the 50 and we'd like to build on that," No. 2 Senate GOP leader John Cornyn of Texas told reporters, emerging from a meeting of top Republicans.
With the party controlling the Senate 52-48 and Democrats uniformly opposed, Republicans need 50 votes to win approval for the bill. Vice President Mike Pence would break a tie.
Hoping to achieve GOP unanimity, Cornyn said leaders were still working on a pair of holdouts: Sens. Bob Corker of Tennessee and Arizona's Jeff Flake.
Senate passage would push Congress a step closer to the first rewrite of the nation's tax code in three decades and a major legislative accomplishment for President Donald Trump.
The bill seemed to be sailing toward passage Thursday, until a report was released by Congress' nonpartisan Joint Committee on Taxation estimating the package would produce budget deficits totaling $1 trillion over the coming decade.
Trump administration officials and leading congressional Republicans have said the measure's tax cuts would spark enough economic growth to pay for the lowered levies. The projection left the votes of several GOP lawmakers in doubt, including Corker of Tennessee and Arizona's Flake.
Sen. Susan Collins, R-Maine, proposed an amendment to let homeowners deduct up to $10,000 in local property taxes on their federal returns. It's similar to a provision in the House-passed bill. Without the deduction, Collins said, it would be "very problematic for me" to vote for the bill.
Amid a whirl of meetings and dramatic votes Thursday evening, the Senate GOP leaders were rewriting the bill behind closed doors. Changes being discussed included rolling back some of the tax cuts after six years to appease deficit hawks — notably Corker and Flake. If leaders could win over Collins and there were no other defectors, Corker and Flake could oppose the measure, and it would still be approved.
At stake is a top priority for President Donald Trump and a Republican Party that considers passage of the measure the best way to preserve the GOP's congressional majorities in next year's midterm elections.
Another faction to be reckoned with: senators supporting millions of businesses whose owners report the firm's profits on their individual tax returns. The vast majority of U.S. businesses, big and small, are taxed this way. Sen. Steve Daines, R-Mont., backed the tax legislation Wednesday after securing an increase in the deduction for business income from 17.4 percent to 20 percent.
Johnson said Friday that he was won over after GOP leaders offered to boost that deduction to 23 percent.
The scramble to alter the bill came after the Senate's parliamentarian ruled that automatic "triggers" designed to guard against big deficits would violate Senate rules. GOP leaders' main concern was winning over the hawks worried about adding more red ink to the mounting $20 trillion deficit.
Senate Majority Leader Mitch McConnell, R-Ky., had expressed confidence early in the day, but he has little margin for error with a 52-48 Republican majority. He can afford to lose only two votes while counting on Vice President Mike Pence to break the tie.
Cornyn said the bill will have "alternative, frankly, tax increases we don't want to do" to address deficit concerns.
Flake said the "trigger" tax increases would raise about $350 billion over 10 years, though he didn't specify which taxes would go up.
In a dramatic turn, Democrats forced a vote on whether to return the measure to the Senate Finance Committee so it could be rewritten to ensure smaller deficits. After holding out for nearly an hour during the vote, Corker, Flake and Johnson eventually joined fellow Republicans to scuttle the Democratic proposal.
Corker has pushed to add automatic tax increases in future years if the package doesn't raise as much revenue as projected.
The overall legislation would bring the first overhaul of the U.S. tax code in 31 years. It would slash the corporate tax rate, offer more modest cuts for families and individuals and eliminate several popular deductions.
Unlike the tax bill passed by the House two weeks ago, the Senate measure would end the requirement in President Barack Obama's health care law that people pay a tax penalty if they don't buy health insurance.
The tax cuts for individuals in the Senate plan would expire in 2026 while the corporate tax cuts would be permanent.
Both the House and Senate bills would nearly double the standard deduction to around $12,000 for individuals and about $24,000 for married couples.
