The “One Big Beautiful Bill Act” (OBBBA), signed on July 4, 2025, delivers major tax updates favoring businesses and real estate investors. From restoring 100% bonus depreciation to extending valuable energy-efficiency deductions, the bill brings back powerful incentives that investors, business owners, and developers have been waiting for. Below we highlight the key fixed-asset related changes – including depreciation boosts, expensing limits, and energy tax breaks – and explain their practical impact on your strategy. Short version: it’s time to dust off those cost segregation studies and plan your capital investments wisely!
OBBBA At a Glance
- 100% Bonus Depreciation is Back — Deduct the full cost of qualified property improvements and qualified property components from acquisitions upfront instead of spreading deductions over decades.
- Section 179 Expensing Boost — Provides an immediate write-off option in addition to bonus depreciation.
- 100% Deduction for Manufacturing & Industrial Buildings — Write off an entire factory or plant in Year 1, drastically cutting the after-tax cost of expansion.
- Energy-Efficient Commercial Building Deduction (179D) – Use It or Lose It — Creates a closing window to claim significant tax breaks for green construction.
- Strategic Purchase Price Allocation & Transfer Tax Savings — Boost immediate depreciation deductions and potentially save on transactional taxes, improving your overall ROI.
Key Fixed Asset Incentives Revitalized in OBBBA

100% Bonus Depreciation is Back
Full first-year write-offs for qualifying assets are permanently reinstated. Under OBBBA, businesses can again claim 100% bonus depreciation on “qualified property” (most new or used tangible assets with a tax life of 20 years or less) placed in service on or after January 20, 2025. This reverses the scheduled phase-down of bonus depreciation (which had dropped to 40% in early 2025) and restores immediate expensing for equipment, furniture, fixtures, and land improvements.
Impact on you: You can now deduct the full cost of qualified property improvements and qualified property components from acquisitions upfront instead of spreading deductions over decades. This puts cost segregation back in the spotlight. By identifying short-life components in buildings, you unlock significant upfront deductions when combined with 100% bonus depreciation. The result is enhanced cash flow, lower taxable income, and a faster return on investment for real estate and capital projects.

Section 179 Expensing Boost
Small and mid-size businesses get a higher cap on immediate expensing for asset purchases. OBBBA raises the Section 179 deduction limit to $2.5 million (up from about $1 million), with a new phase-out threshold at $4 million of assets placed in service per year. In other words, you can elect to expense up to $2.5M of qualifying property purchases annually, and the deduction only starts phasing out if you invest over $4M in a year (limits indexed for inflation after 2025). Qualifying assets include most machinery, equipment, furniture and certain non-structural real property improvements like HVAC units, roofs, security systems, doors, insulation, and windows.
Impact on you: This expanded Section 179 expensing provides an immediate write-off option in addition to bonus depreciation. It is especially valuable for businesses purchasing assets in states that don’t allow federal bonus depreciation but do conform to Section 179. In practical terms, more of your capital expenditures (from work vehicles to air conditioners) can be deducted in the first year, simplifying asset planning for smaller companies.
Note: Section 179 still generally requires an active trade or business use. Pure rental property owners must rely on bonus depreciation instead.

100% Deduction for Manufacturing & Industrial Buildings
To spur domestic production, OBBBA introduced a new 100% depreciation incentive for certain facilities. New Section 168(n) allows immediate expensing of the entire cost of qualified production property – essentially, newly constructed nonresidential real estate used in manufacturing, processing or warehousing. To qualify, the facility’s construction must begin between January 20, 2025 and the end of 2028, and it must be placed in service by the end of 2030. There are important caveats: the building must be owner-occupied for a production activity, and portions used for offices, lodging, R&D, or sales are excluded from this write-off.
Impact on you: This is a game-changer for manufacturers and industrial developers – you can write off an entire factory or plant in Year 1, drastically cutting the after-tax cost of expansion. A cost segregationanalysis is crucial here to separate any non-qualifying spaces (offices, etc.) from the production areas so that you maximize the 168(n) deduction. By leveraging this incentive, companies in manufacturing, agriculture, or refining can reinvest tax savings directly into operations and growth.

Energy-Efficient Commercial Building Deduction (179D) – Use It or Lose It
The popular 179D deduction for green building investments has been preserved – but not for long. This provision offers up to $5.00 per square foot in tax deductions for installing energy-efficient HVAC, lighting, and building envelope systems in new or renovated commercial buildings. OBBBA keeps the enhanced 179D incentive (as expanded under recent laws) in place through 2026, then sunsets it. Projects that begin construction by June 30, 2026 can still qualify for the deduction, but any building work started after that date will not be eligible.
Impact on you: This creates a closing window to claim significant tax breaks for green construction. Commercial real estate owners and developers can substantially reduce project costs by designing buildings that meet the energy efficiency criteria – potentially millions in tax savings on large office, multifamily, or industrial projects. Designers and engineers also benefit: 179D allows deductions to be allocated to the project designers for government and non-profit buildings, providing a nice reward for architects and engineers who plan energy-saving systems. The key takeaway is to accelerate any energy-efficient building plans now. By 2027, this incentive will be gone, so consider completing retrofits or new construction before the deadline to lock in the tax deductions while they last.

Strategic Purchase Price Allocation & Transfer Tax Savings
With bonus depreciation back at 100%, how you allocate the purchase price of real estate has never been more important. When you buy a property, the price should be divided among land (non-depreciable) and various depreciable asset categories: building, land improvements (landscaping, site work, paving), and personal property (fixtures, equipment, furniture). Proper purchase price allocation based on fair market value allows you to maximize the basis in short-life assets that qualify for immediate depreciation. For example, by carving out value for 5-year appliances and 15-year site improvements in a building acquisition, those portions can be expensed immediately under bonus depreciation instead of being stuck on a 39-year schedule.
Impact on you: A professional cost segregation or purchase price allocation study can unlock huge tax savings upfront for buyers of commercial real estate. Additionally, it can cut your real estate transfer taxes. Many states and municipalities tax only the real estate portion of a sale, not personal property. If a transaction is mistakenly reported as 100% real estate, the transfer tax bill will be inflated. By identifying and valuing the personal property included in a sale before closing, buyers and sellers can exempt that portion from transfer tax. In one case study, allocating roughly 25% of a $200 million property price to furniture, fixtures & equipment saved about $600,000 for the parties in combined state and city transfer taxes. The bottom line: engage experts early to map out your asset allocation – you’ll boost immediate depreciation deductions and potentially save on transactional taxes, improving your overall return on investment.
Practical Takeaways
-
Plan Ahead
These tax changes reward those who plan their acquisitions and projects strategically. If you’re considering a major purchase or build-out, timing is critical. For instance, an asset placed in service in late January 2025 could yield a 100% write-off, whereas one placed just a few weeks earlier (before the new law’s start date) gets only 40%. Align your capital expenditures to take full advantage of the restored incentives.
-
Leverage Cost Segregation
Nearly every favorable provision (from bonus depreciation to the manufacturing facility expensing) ties back to isolating shorter-life assets. A cost segregation study is a proven method to identify those components and accelerate depreciation on them. With OBBBA’s changes, the value of cost segregation is higher than ever. It can immediately translate into tax savings and increased cash flow in year one.
-
Don’t Miss Expiring Breaks
If you have plans for energy-efficient upgrades or developments, act soon. The clock is ticking on 179D commercial building deductions and 45L home credits. Likewise, evaluate any pending green energy investments (solar, EV infrastructure) under the lens of the new phase-outs. Taking advantage of these before they expire could mean the difference in project viability.
