About the One Big Beautiful Bill Act
The One Big Beautiful Bill Act (OBBBA) was signed into law in 2025 as one of the most significant tax reforms in recent years. The legislation introduced new deductions for individual workers, expanded existing provisions, and reversed several phase-outs that were reducing business competitiveness.
Key Individual Provisions
The OBBBA directly reduces the tax burden on working Americans through several targeted provisions. The "no tax on tips" provision allows tipped workers to deduct up to $25,000 in qualified cash tips from their taxable income. The "no tax on overtime" provision creates a similar $12,500 deduction for overtime premium pay. Both are above-the-line deductions available even to taxpayers who take the standard deduction.
For homeowners in high-tax states, the SALT deduction cap was quadrupled from $10,000 to $40,000, making itemized deductions viable for millions more filers. Seniors age 65 and older receive an extra $6,000 standard deduction that stacks on top of existing age-based additions. Buyers of new US-assembled vehicles can deduct up to $10,000 in car loan interest. And the Trump Account provision creates a one-time $1,000 government contribution to a retirement account for eligible children.
Key Business Provisions
The OBBBA restores 100% bonus depreciation under Section 168(k), which had been phasing down from 100% in 2022 to just 20% in 2026 under prior law. This means businesses can deduct the full cost of qualifying equipment and assets in the year they are placed in service. The Act also reverses the Section 174 R&D amortization requirement, allowing businesses to immediately deduct research and development expenses rather than spreading them over 5 years (domestic) or 15 years (foreign). For a business spending $1 million on domestic R&D at a 21% tax rate, this creates an immediate $168,000 cash flow advantage in year one.
