A proposal by Senate Republicans would adjust the pace at which some crucial home energy efficiency and electric vehicle tax credits are phased out in timelines different from what House Republicans proposed in the multitrillion-dollar tax bill they passed last month.

Senate Republicans included a tax break estimated to be worth more than $1 billion for oil and gas producers in their version of President Donald Trump’s sprawling fiscal package. The provision would allow energy companies subject to a 15% corporate alternative minimum tax to deduct certain drilling costs when calculating their taxable income.

The Senate Finance Committee on Monday released its version of the GOP’s package that calls for enacting sweeping cuts to Medicaid and preventing a multi-trillion dollar tax hike on Americans.
