Mehrotrat t On July 4, 2025, President Donald J. Trump signed into law the One Big Beautiful Bill Act (OBBBA). This new law was built on the foundations of its immediate predecessor, the 2017 Tax Cuts and Jobs Act (TCJA). This Essay examines the historical roots and contemporary implications of these two laws. It argues that both acts reflect continuities and ruptures in the recent history of U.S. tax law and fiscal policymaking. On the one hand, the two laws are a continuation of decades-long trends in American tax policy- trends marked by persistent tax cutting, increasing partisan polarization, and a growing disregard for fiscal responsibility. Yet these two laws also depart from earlier episodes marked by bipartisan efforts to address fiscal challenges through compromise and revenue-conscious reform. To highlight the continuities and ruptures, the Essay further analyzes three key historical analogs: (1) the Bush tax cuts of 2001 and 2003, (2) the 1990s Omnibus Budget Reconciliation Acts, and (3) the 1983 Greenspan Commission on Social Security Reform. While earlier tax laws established the partisan use of reconciliation and temporary tax relief, the TCJA and OBBBA expanded this model into permanent, deficit-financed legislation. In contrast, the Omnibus Acts t J.D. 2025, Northwestern Pritzker School of Law; B.A. 2019, Washington & Jefferson College. tt Stanford Clinton Sr. and Zylpha Kilbride Clinton Research Professor of Law, Northwestern Pritzker School of Law; Affiliated Professor of History, Northwestern University; and Research Professor, American Bar Foundation.
