WASHINGTON—Senate Republicans detailed major revisions of the House’s giant tax-and-spending bill, offering more permanent business tax breaks, deeper cuts to Medicaid, slower phaseouts for clean-energy tax credits and a much lower cap on the state and local tax deduction.

The legislation keeps some House provisions, like new Medicaid rules, while making significant changes in other areas, including Medicare and the state and local tax deduction.

WASHINGTON — Senate Republicans on Monday unveiled a draft of their vision for key tax and spending cuts, setting up an intra-party conflict over legislation enacting President Donald Trump’s agenda.
