On May 22, 2025, the House of Representatives passed H.R. 1, the One Big Beautiful Bill Act—a sweeping $3.8 trillion budget reconciliation package. This landmark legislation includes a wide range of federal tax provisions that could significantly impact individuals, businesses, and international taxpayers.
Although the bill is likely to be revised in the Senate, many of the core proposals provide early insight into the potential direction of tax policy. Read on for an AICPA overview of the most important tax-related elements of the bill as currently drafted and how they might influence your tax planning in the months ahead.

- Low-Income Housing Tax Credit: The 9% credit allocation is increased for 2026–2029, the bond-financing threshold for the 4% credit is lowered, and Indian and rural areas are designated as "difficult development areas."
- Opportunity zones: A new round of opportunity zones is created for 2027–2033, with revised eligibility and incentives, including special rules for rural areas.
