July 9, 2025 - The One, Big, Beautiful Bill Act (or, more technically, ”an Act to provide for reconciliation pursuant to title II of H. Con. Res. 14.“) represents a sweeping legislative initiative that includes significant changes to the federal tax code.

This legislative package draws extensively on key elements of the 2017 Tax Cuts and Jobs Act (TCJA), aiming to make permanent many of its expiring provisions. It also introduces new tax policies designed to support working families, encourage economic growth in rural communities, simplify tax administration, and unwind certain climate and clean-energy related tax credits enacted in recent years.

Many of the provisions described herein would be effective for tax years beginning after December 31, 2025, or following the date of enactment (July 4, 2025), although certain provisions are retroactive or prospective in nature.

As of this publication date, July 9, 2025, this summary cites provision section numbers as set forth in the Senate Amendment to H.R. 1. Future updates will reflect the final section numbers as published in Public Law 119-21, along with any subsequent technical corrections.
