The House of Representatives passed a budget blueprint on Thursday that’s key to Republicans’ tax-cutting goals, approving the measure even as some GOP lawmakers rebelled.

The House’s vote paves the way for the Senate to later pass a tax-cut package with a simple majority, instead of 60 votes. President Donald Trump and congressional Republicans campaigned on major tax reform, and Thursday’s vote moves them a step closer.

But many issues remain to be ironed out, with lawmakers and the White House having released only a tax-reform framework. Critical decisions remain on, for example, the tax treatment of 401(k) plans. Trump has said there will be “no change” for the plans, but House Speaker Paul Ryan didn’t rule out it out when pressed by reporters following the vote.

House Ways & Means Committee Chairman Kevin Brady said he plans to introduce a bill on Nov. 1, and his panel will begin considering it on Nov. 6.

The budget blueprint — already passed in the Senate — cleared the House on a vote of 216 to 212. A total of 20 Republicans defected, including Reps. Peter King and Lee Zeldin of New York, who are wary that a state and local tax deduction that benefits their constituents will be taken away in the final tax bill. Reps. Frank LoBiondo and Tom MacArthur of New Jersey, another state where the deduction is valuable, were also among those voting “no.”

The framework proposes getting rid of the deduction. Ryan said the Ways & Means panel would work with members to “find a solution” on the state and local issue.

In addition to cutting individual and business rates, the framework seeks to roughly double the standard deduction; allows immediate expensing of capital investments; and calls for what’s known as a territorial system in which overseas profits of American companies aren’t subject to U.S. taxes.

The budget passed Thursday would add about $1.5 trillion to deficits over 10 years.
