The One Big Beautiful Bill Act (OBBBA) has permanently reinstated 100% bonus depreciation for qualifying assets that were placed in service after January 19, 2025. This means that investors are able to immediately write off the entire cost of their eligible business property and improvements as opposed to spreading those deductions across the span of years.

The One Big Beautiful Bill Act (OBBBA), which was reinstated as of July 2025, is a landmark legislation that has reversed the previous phase-out-schedule that was projected to reduce deduction down to 40% for 2025 and 20% for 2026. This tax reform is a big victory for capital-intensive industries, significantly transforming the financial realities for business owners and real estate investors.

Under the former legislation, investors were forced to sit by and watch as their first-year write-offs steadily declined. The deduction dropped to 80% in 2023, 60% in 2024 and was set to continue this trajectory before the OBBA was officially reinstated. Now, investors can rest assured that this powerful tax incentive will no longer be diminished. Online tools like a bonus depreciation calculator are an invaluable asset for investors who seek to estimate their potential upfront tax savings on newly acquired commercial or residential properties. 

The Legislative Shifts Implemented Under the OBBA

Before the OBBA was enacted, the tax code mandated a strict reduction in first-year write-offs, with the bonus depreciation set to drastically decrease over time. This phase-out created diminishing returns for capital expenditure and added complications to long-term corporate budgeting.

However, the OBBA has mitigated this eventuality and ensured a return to 100% depreciation. Some of the most prominent details of this tax reform include:

• An effective date stipulating that only qualifying assets acquired after January 19, 2025, are eligible for the 100% rate.
• Any assets acquired under a written binding contract either on or before January 19, 2025, are subject to the previous phase-out percentages and don’t qualify for the 100% rate.
• In order to qualify for the 100% bonus depreciation, the assets must fall under the Modified Accelerated Cost Recovery System (MACRS) with a recovery period of 20 years or less.

If you are an investor looking to capitalize on the benefits offered by the reinstated OBBA, it’s important that you first ascertain whether or not your assets qualify for the 100% bonus depreciation based on their date of acquisition.

Understanding The Core Eligibility and Tax Rules

The bonus depreciation rules explained in recent regulatory updates are far easier to navigate if when you have an understanding of how asset classification works. The IRS has implemented strict boundaries between what can be classified as structural long-term real estate and what falls under the category of short-life personal property.

Tangible Personal Property

This category encapsulates your core corporate assets, including but not limited to:

• Manufacturing machinery
• Production equipment
• Office furniture
• IT hardware
• Specialized appliances

Qualified Improvement Property (QIP)

This is used in reference to the internal and non-structural improvements that you may have made to an existing commercial building. 

Some notable exclusions include:

• Structural frameworks
• Building expansions
• Escalators
• Elevators

Heavy Business Transportation

Any vehicle that exceeds a Gross Vehicle Weight Rating (GVWR) of 6,000 pounds will bypass the standard luxury automobile deductions. These vehicles are eligible for full first-year expensing, based on the percentage of their documented business usage.

The statute has stipulated that both brand-new and pre-owned equipment qualify for the incentive. In order for used property to be deemed eligible, it just needs to be new to you. This means you can’t have previously owned, leased or used the asset.

What The Implications Are for Real Estate Investors

Although the standard commercial buildings with a 39-year structural life and residential buildings with a 27,5 year structural life are inherently restricted from the bonus depreciation, real estate investors have taken to implementing engineering-based strategies in order to access the 100% deduction.

A cost segregation study will enable you to dissect your asset into various components, which you can then implement accelerated depreciation strategies with to create significant upfront liquidity within your first year of ownership.

This study will separate the non-structural elements and land improvements from the core envelope of your building, allowing these components to be deducted on an accelerated schedule. Once the engineering metrics have reclassified these components into 5, 7 and 15 year MACRS recovery tracks, they will immediately become eligible for the full first-year accelerated depreciation under the OBBBA.

Tax Reform for Real Estate Investors

The reinstatement of the One Big Beautiful Bill Act (OBBBA) has been a welcome respite for real estate investors who were faced with drastic cuts to their eligible tax deductions under the previous legislation. The 100% bonus depreciation incentive has once again enabled real estate investors to maximize their investments, and the added benefits of implementing a cost segregation study to incorporate accelerated depreciation to their assets has reshaped the financial outlook for investors going forward.
