Executive Summary

The One Big Beautiful Bill Act (OBBBA), enacted on July 4, 2025, represents one of the most significant overhauls of federal tax incentives affecting real estate since the Tax Cuts and Jobs Act of 2017. Several provisions dramatically expand cost recovery through permanent full expensing, while others compress or eliminate energy related incentives. Real estate developers, investors, manufacturers, and tax professionals should carefully evaluate project timelines, cost allocation strategies, and capital planning in order to optimize benefits within the new statutory windows.

Permanent Restoration of 100% Bonus Depreciation under §168(k)

OBBBA permanently restores 100% bonus depreciation for qualified property acquired and placed in service after January 19, 2025. Eligible property includes tangible assets with recovery periods of 20 years or less, qualified improvement property, and certain used assets that meet acquisition requirements. However, there are nuances that need to be evaluated, such as the written binding contract rule, to determine if an asset placed in service after January 19, 2025 is eligible for 100% bonus depreciation.

Planning Opportunity: Cost segregation studies remain extremely valuable because they identify short lived assets that are eligible for immediate expensing. For real estate intensive taxpayers, this permanently restores front loaded deductions that significantly improve after tax cash flow.

Bonus Depreciation Example: A newly constructed hotel placed in service in March 2026 includes $8.2 million of assets with recovery periods of 5, 7, and 15 years. Under the restored 100% bonus depreciation rules, the full $8.2 million may be deducted immediately.

Qualified Production Property Expensing under §168(n)

OBBBA creates §168(n), which permits immediate expensing of the portion of newly constructed nonresidential real property used in a Qualified Production Activity. Qualified production refers to manufacturing, production or refining activities that substantially transform tangible personal property.

Eligibility Requirements

• Construction must begin after January 19, 2025 and before January 1, 2029.
• The property must be placed in service before January 1, 2031.
• Only the portion of the structure used directly in the production process qualifies.
• Office, administrative, retail, and similar areas do not qualify.

Qualified Production Property Example: A 240,000 square foot industrial facility is placed in service in 2028. Of this total, 170,000 square feet are used for fabrication and assembly and 40,000 square feet are used for warehousing and loading activities. These areas may qualify for expensing. The remaining 30,000 square feet of administrative office area would be depreciated over 39 years.

Taxpayers may also apply 100% bonus depreciation to short-lived assets identified within both the qualifying and non-qualifying portions of the building.

Permanent Restructuring of the Opportunity Zone Program

The OBBBA permanently extends the Qualified Opportunity Zone program, with a new designation cycle effective January 1, 2027. The Act narrows eligibility criteria for qualifying census tracts and introduces enhanced incentives for rural investment.

Key Changes

• New Opportunity Zones are designated on a rolling 10‑year cycle.
• A Qualified Rural Opportunity Fund (QROF) provides a 30% basis step‑up for rural investments held for at least five years.
• The substantial improvement requirement for rural property is reduced from 100% to 50%.

Opportunity Zone Example: A taxpayer invests $5 million of capital gain into a Qualified Rural Opportunity Fund in 2027. After a five‑year holding period, the investor receives a 30% basis increase. Any post‑investment appreciation may be fully excluded if the investment is held for at least ten years, subject to the program’s 30‑year maximum holding period.

Increased §179 Expensing Limits

OBBBA increases the §179 deduction limit to $2.5 million and begins phase out at $4 million. Eligible property includes equipment, off-the-shelf software, and certain improvements to non-residential buildings such as HVAC systems, fire protection, and security enhancements.

Increased Expensing Limits Example: A manufacturer invests $3.2 million in equipment for a facility expansion. The taxpayer may expense $2.5 million under §179 and deduct the remaining $700,000 using bonus depreciation.

§179D Energy Efficient Commercial Buildings Deduction Ending for Projects Beginning Construction After June 30, 2026

§179D deduction ceases to apply to projects for which construction begins after June 30, 2026. To qualify, taxpayers must begin construction on or before this deadline. Once construction has started, the project remains eligible for the 179D deduction even if it is completed or placed in service in later years. Eligible improvements include energy‑efficient lighting, HVAC systems, building envelope upgrades, and whole‑building performance measures certified under IRS‑approved energy modeling.

§179D Example: A taxpayer begins construction of a qualifying energy‑efficient facility in May 2026. Even if construction concludes in 2027 or later, the project remains eligible for the 179D deduction because construction began before the June 30, 2026 cutoff.

§45L Energy Efficient Home Credit Ending June 30, 2026

§45L credit terminates for homes sold or leased after June 30, 2026. This includes single family, multifamily, and manufactured homes that meet ENERGY STAR or Zero Energy Ready Home standards.

§45L Example: A multifamily development beginning construction in March 2025 must have all units completed and placed in service before the June 30, 2026 deadline in order to qualify.

§48E Clean Electricity Investment Credit

OBBBA significantly accelerates the elimination of the Clean Electricity Investment Tax Credit for solar and wind facilities.

• Solar and wind construction must begin by July 4, 2026.
• Solar and wind projects that begin after this date must be placed in service before December 31, 2027 to qualify.
• Energy storage, geothermal, combined heat and power, and similar property remain eligible until a phase out begins after 2032.

§45X Advanced Manufacturing Production Credit

§45X is preserved, but OBBBA tightens eligibility and accelerates phaseouts.

• Wind components are no longer eligible for credits after 2027.
• Other eligible components begin phasing out after 2030.
• Credits are unavailable if the taxpayer receives material assistance from certain foreign entities.

§45X Example: A battery manufacturer sourcing electrode materials from a prohibited foreign entity may lose eligibility for the credit unless the supply chain is adjusted.

Conclusion

The One Big Beautiful Bill Act creates wide ranging opportunities for accelerated tax deductions and capital recovery, while compressing the timeframe for many energy related credits. Proactive planning between 2025 and 2031 will be essential for taxpayers seeking to fully optimize available incentives.
