What Qualifies for Bonus Depreciation in 2026? A Guide for Real Estate Investors

Bonus depreciation can create significant tax-saving opportunities for real estate investors, but not every property or building component qualifies. Understanding which assets are eligible, and how to identify them, can make a substantial difference in your depreciation strategy.

For owners of apartment buildings, shopping centers, industrial facilities, hotels, and investment portfolios, one of the most important questions is: What qualifies for bonus depreciation, and how can I take advantage of it?

The answer often begins with understanding how different components of a property are classified for tax purposes.

What Is Bonus Depreciation?

Bonus depreciation is a federal tax provision that allows businesses and real estate investors to deduct a qualifying percentage of eligible property costs in the year the assets are placed in service, rather than spreading those deductions over several years.

Under federal legislation enacted in July 2025, 100% bonus depreciation was restored for qualifying property acquired after January 19, 2025, subject to applicable requirements.

For real estate investors, this can create an opportunity to accelerate deductions on eligible assets within a building or property.

However, the provision does not generally allow an investor to immediately deduct the entire cost of a commercial building.

The distinction lies in which assets qualify.

Which Real Estate Assets Qualify for Bonus Depreciation?

Commercial buildings and residential rental buildings are typically depreciated over 39 years and 27.5 years, respectively, under the general federal depreciation system.

But not every component associated with a property must necessarily follow that same recovery period.

Certain assets may qualify for shorter depreciation periods, including 5, 7, or 15 years. Many qualifying assets with recovery periods of 20 years or less may also be eligible for bonus depreciation.

Depending on the property, qualifying assets may include:

• Certain removable carpeting and specialized flooring.
• Appliances and qualifying equipment.
• Certain decorative or specialty lighting.
• Dedicated electrical systems serving qualifying equipment.
• Certain specialized plumbing installations.
• Parking areas, fencing, landscaping, and qualifying land improvements.
• Certain equipment and fixtures associated with commercial operations.

Eligibility depends on the asset's function, construction, use, and applicable tax classification. For example, a building's general HVAC system is not automatically eligible for a shorter depreciation life simply because it appears within a cost segregation study.

That is why accurately identifying and classifying individual assets matters.

How Does Cost Segregation Help Identify Qualifying Assets?

A cost segregation study examines a property's assets and associated costs to determine whether components can be properly classified into shorter depreciation categories.

Rather than treating an entire property improvement as one long-lived building asset, the analysis identifies qualifying personal property and land improvements that may have shorter recovery periods.

An engineering-based study evaluates relevant building components, construction details, property use, and available cost documentation to support the classifications.

For example, a multifamily apartment property may contain qualifying appliances, carpeting, and land improvements. A shopping center may have eligible site improvements and certain tenant- specific assets. An industrial property may include specialized systems associated with manufacturing or operational equipment.

The purpose is not simply to produce a larger depreciation estimate. It is to identify eligible assets and establish supportable classifications that can be used in calculating allowable tax deductions.

Can Previously Owned Buildings Qualify?

Potentially, yes.

Bonus depreciation is not limited exclusively to newly constructed buildings.

Certain qualifying used property can also be eligible, depending on when and how it was acquired, its prior use by the taxpayer, related-party restrictions, and other requirements.

This is particularly important for real estate investors who acquire existing commercial buildings or investment properties.

A property purchased recently may contain eligible components that qualify for accelerated deductions, even though the building itself was constructed years earlier.

The acquisition date and placed-in-service date are important considerations, so an owner should evaluate eligibility using the rules applicable to that particular transaction.

What About Properties Acquired Before 2026?

Properties acquired in earlier years may still present opportunities for cost segregation.

If eligible assets were not properly classified when the property was first placed in service, a look- back study may identify depreciation deductions that were not previously claimed.

Depending on the circumstances, a taxpayer may be able to address certain accounting method changes through IRS Form 3115.

However, conducting a study in 2026 does not automatically make property acquired in an earlier year eligible for the restored 100% bonus depreciation rate. The applicable percentage and available deductions depend on the underlying acquisition and placed-in-service facts.

A qualified tax professional should evaluate those details before changes are made.

Why Bonus Depreciation Matters for Commercial Real Estate

The financial implications of accelerated depreciation can become particularly meaningful for larger properties and portfolios.

Consider an investor purchasing a substantial apartment complex. The purchase may include numerous building components and site improvements with different depreciation classifications.

An engineering-based cost segregation study can help determine what portion of the depreciable property basis may qualify for shorter recovery periods.

Identifying those assets may allow the investor to recognize additional depreciation deductions earlier in the ownership period, potentially improving after-tax cash flow.

For real estate investment groups managing multiple properties, the opportunity can extend beyond an individual transaction.

Coordinated depreciation analysis across acquisitions, renovations, and existing properties can become an important part of broader portfolio tax planning.

Does Bonus Depreciation Always Reduce an Investor's Current Tax Bill?

Not necessarily.

Accelerated depreciation generally changes when deductions are claimed, but the immediate tax benefit depends on an investor's individual circumstances.

Important considerations include:

• Taxable income and applicable tax rates.
• Passive activity loss limitations.
• At-risk and other deduction limitations.
• Ownership structure and partnership allocations.
• State tax treatment.
• Future property dispositions and depreciation recapture.

A deduction that cannot currently be used may still have value in future years, depending on the applicable rules.

Investors should work closely with their CPA or tax advisor to determine how available depreciation deductions fit their broader financial and tax strategy.

How Can Investors Determine Whether Their Property Qualifies?

The starting point is a review of the property and its financial circumstances.

A preliminary evaluation may consider the property's type, acquisition date, purchase price, depreciable basis, improvements, and previous depreciation treatment.

For commercial real estate owners, the evaluation should also account for the potential value of accelerating deductions relative to the cost of conducting a detailed study.

An experienced cost segregation provider can help identify whether further analysis is warranted and what records may be needed.
