What CPAs Need to Know About the One Big Beautiful Bill Act

On July 4, 2025, President Trump signed the One Big Beautiful Bill Act (OBBBA) into law, marking the most significant overhaul of the federal tax code since the Tax Cuts and Jobs Act (TCJA) of 2017. Passed through budget reconciliation, the OBBBA permanently extends several key TCJA provisions that were set to expire and introduces new provisions affecting individuals, businesses and the tax professionals who serve them. These changes carry significant implications for tax planning and compliance, making understanding and implementation essential for CPAs and tax professionals ahead of the 2025 filing season.

Key Highlights

1. Tip and overtime pay: A new deduction was established for earned income from tips and overtime pay for tax years 2025 through 2028, creating potential tax savings for qualifying taxpayers.
2. Senior deduction: A temporary personal exemption deduction of up to $6,000 is available for individuals aged 65 or older for tax years 2025 through 2028.
3. Trump accounts: This new tax-favored savings account is designed to support future investments in education, housing, and entrepreneurship for children.
4. Car loan interest deduction: For tax years 2025 through 2028, a new deduction is available for interest on certain car loans, offering potential tax benefits for qualifying personal-use vehicles.
5. Section 1202 exclusion: The OBBBA expands the Section 1202 exclusion for qualified small business stock by introducing tiered gain exclusions based on holding periods, increasing the per-issuer gain exclusion cap, and raising the corporate gross asset limit.
6. SALT deduction dap: The SALT deduction cap is increased to up to $40,000 (indexed for inflation through 2029) with a phase-down for high-income taxpayers.
7. Bonus depreciation: The OBBBA permanently reinstates 100% bonus depreciation and creates a new special depreciation allowance for qualified production property.
8. Key TCJA provisions made permanent: The OBBBA makes several TCJA provisions permanent, including lowered individual tax brackets, increased standard deductions, and the repeal of personal exemptions, providing greater long-term planning certainty for individuals and families.
