Senate Tax Megabill: Key Provisions and What They Mean for You

On July 1, 2025, the U.S. Senate advanced the “One Big Beautiful Bill Act” with a narrow 51–50 vote, with Vice President JD Vance casting the decisive tie-breaking vote. The vote followed more than 20 hours of negotiations and amendments, marking a significant step forward for the sweeping tax and spending legislation. 

The bill now returns to the House where lawmakers must reconcile differences between the two versions before a final vote. Several House Republicans have expressed concerns over the Senate’s changes, particularly deeper Medicaid cuts and a larger projected deficit, warning that the revised bill could struggle to gain support from both Republican conservatives and vulnerable moderates. 

This legislation spans more than 900 pages, with numerous amendments and last-minute changes made during the final hours of Senate debate. Aldrich will continue to monitor developments and provide timely updates as more details emerge, and the bill moves through the reconciliation process. 

Senate Bill: Individual Tax Provisions

For individuals, the Senate-passed bill proposes a range of tax relief measures aimed at middle- and upper-income households. of the key changes include:

  • SALT Deduction Cap: Temporarily increased to $40,000 through 2029, then reverts to $10,000 in 2030. A phase-down applies for taxpayers with modified adjusted gross income (MAGI) over $500,000.  
  • Tips and Overtime: Introduces deductions for tip income (up to $25,000) and overtime pay (up to $12,500), both phased out for higher-income earners.
