What is the One Big Beautiful Bill, and How Can SMEs Benefit from
100% Bonus Depreciation?
Executive Summary
The passage of the One Big Beautiful Bill Act (OBBBA) permanently restores 100% first-year bonus depreciation for qualifying business assets. By permanently reversing scheduled multi-year phaseouts, small and medium-sized enterprises (SMEs) have an unparalleled opportunity to accelerate tax deductions, preserve liquidity, and modernize operations.
- Legislative Overview: The One Big Beautiful Bill Act
Signed into law on July 4, 2025, the OBBBA delivers comprehensive updates to the U.S. Internal Revenue Code. Under prior law (TCJA), bonus depreciation was subject to a steep annual phaseout (80% in 2023, 60% in 2024, down to 0% by 2027). The OBBBA permanently eliminates this reduction for qualified property with a recovery period of 20 years or less, acquired after January 19, 2025.
100% — Permanent Bonus Depreciation
$2.5M — Section 179 Expense Limit
20% — Permanent QBI Deduction
$4.0M — Sec. 179 Phaseout Threshold
Beyond bonus depreciation, key provisions strengthening small business growth include:
Section 179 Cap Elevation: Expands maximum immediate expensing to $2.5 million, with phaseouts starting at $4.0 million (indexed for inflation starting in 2026).
Qualified Production Property (QPP): Temporary 100% deduction under IRC §168(n) for eligible domestic production real property constructed after Jan. 19, 2025.
R&D Amortization & QBI Relief: Enhanced R&D expense deduction rules alongside permanent 20% QBI deductions for pass-through entities.
Strategic Financial Benefits for SMEs
Immediate Cash Flow Acceleration
Full first-year write-offs reduce current taxable income immediately, providing instant working capital liquidity to reinvest in operations or hiring.
Incentivized Modernization
Reduces net after-tax costs for purchasing machinery, computer hardware, specialized vehicles, and off-the-shelf software required to scale.
Multi-Tool Tax Stacking
Combining expanded Section 179 caps with uncapped 100% bonus depreciation allows business owners to optimize write-offs across diverse asset classes.
Long-Term Budgeting Certainty
Permanent code rules remove the pressure of sunset provisions, allowing executive leadership to build steady multi-year capital expenditure plans.
Three-Step Implementation Roadmap
- Identify & Categorize Qualifying Assets
Verify that assets acquired after Jan. 19, 2025 fall under 20-year recovery periods (machinery, IT hardware, furniture, and Qualified Improvement Property). Note: Assets bound by pre-existing contracts signed before Jan. 20, 2025 follow prior phase-down rules.
Optimize Timing & Elective Rates
Ensure assets are fully placed in service within the targeted tax year. For tax years ending after Jan. 19, 2025, businesses may strategically elect a reduced 40% rate to prevent expiring Net Operating Loss (NOL) carryforwards or tax credit dilution.
Execute Cost Segregation Studies
For commercial building acquisitions or renovations, a cost segregation study reclassifies building elements (lighting, specialized plumbing, HVAC) into 5-, 7-, or 15-year lives—instantly opening them to 100% bonus depreciation write-offs.

Frequently Asked Questions
Q: Can an SME utilize both Section 179 and 100% bonus depreciation in the same tax year?
A: Yes. Section 179 is typically applied first to target specific assets up to its income limit, followed by bonus depreciation on remaining costs to maximize upfront write-offs.
Q: Why might a company elect out of 100% bonus depreciation?
A: If a business expects higher future tax rates or has existing Net Operating Losses (NOLs) that risk expiring, spreading depreciation deductions over future years provides greater aggregate tax savings.
