Bonus Depreciation for Commercial Real Estate Investors
2026 Guide to Bonus Depreciation and Cost Segregation
Tax-aware acquisition strategy
Accelerate depreciation. Preserve capital for what’s next.
A cost segregation study may move qualifying components of a commercial property into shorter recovery periods—making them eligible for immediate depreciation under current federal law. The real question is whether your facts let you use it.
The core distinction
Two tools. One accelerated timeline.
Cost segregation identifies the assets. Bonus depreciation determines how quickly eligible basis may be deducted. A study separates qualifying 5-, 7-, and 15-year components from the 39-year commercial building structure.
Land is excluded.
Land is not depreciable and must be separated from the property’s basis.
The building is not “100% deductible.”
The ordinary structural portion generally remains 39-year property.
Used property may qualify.
Eligible components can qualify when acquisition and related-party requirements are met.

The value test
A valid deduction is not always a usable deduction.
Model the strategy through ownership and exit—not just the first tax return.
01
Can you use the loss?
Rental losses are generally passive. Material participation, real estate professional status, ownership structure, and passive income determine when the benefit can be used.
02
Does your state conform?
State rules may decouple from federal bonus depreciation, creating a second schedule and changing the projected cash-flow benefit.
03
What happens at exit?
Accelerated deductions can increase depreciation recapture in a taxable sale. Hold period, future rates, and the planned disposition matter.
What a study examines
Eligibility is determined component by component.

Land improvements
Certain parking areas, sidewalks, fencing, landscaping, and exterior site work.

Qualified improvements
Certain interior improvements to existing nonresidential buildings when statutory requirements are met.

Building structure
Structural walls, roof, and other core building systems generally remain long-life property.
A retail-specific exception
Why fuel retail deserves a separate analysis.
A qualifying retail motor-fuels outlet is treated as 15-year property rather than ordinary 39-year commercial real estate. Under current federal bonus-depreciation rules, that distinction may bring substantially more of the depreciable building basis into the first-year analysis.
The property must satisfy at least one IRS test.
≤1,400The outlet building is no larger than 1,400 square feet.
≥50%At least half of the property’s gross revenue is derived from petroleum sales.
≥50%At least half of the floor area is devoted to petroleum marketing sales.
The landlord can qualify. IRS Revenue Ruling 97-28 states that owner-operator status is not required. A landlord may receive 15-year treatment when the property itself meets the retail motor-fuels definition. The tenant’s operating data, building use, acquisition structure, and supporting documentation still need professional review.

Investor questions
The short answers.
Does the entire commercial building qualify?
Usually not. Land is not depreciable, and the ordinary structural building generally remains 39-year property. A cost segregation study identifies components that may qualify for shorter recovery periods.
Can a used NNN property qualify?
Certain used property can qualify when the statutory acquisition requirements are met. NNN lease structure itself does not determine eligibility.
Can the deduction offset W-2 income?
Not automatically. Passive-activity limitations generally control how rental losses can be used. Your tax advisor must evaluate your specific participation and income profile.
Can I catch up depreciation on a property I already own?
Potentially. A look-back study and accounting-method change may allow eligible catch-up depreciation without amending each prior return. Your CPA should determine whether Form 3115 applies.
How does this interact with a 1031 exchange?
A 1031 exchange can defer qualifying gain and recapture, but it does not automatically create a full new depreciable basis. Carryover basis, additional investment, boot, and newly acquired components should be modeled together.

How Bonus Depreciation and Cost Segregation Work
What changed under current law?
The One Big Beautiful Bill Act restored a permanent 100% additional first-year depreciation deduction for eligible property acquired and placed in service after January 19, 2025. According to IRS Notice 2026-11 guidance, qualifying property generally includes tangible property depreciated under MACRS with a recovery period of 20 years or less. It can include new property and certain used property.
The acquisition date and placed-in-service date both matter. A property is generally placed in service when it is ready and available for its intended business use—not simply when the purchase contract is signed. Transitional rules may apply to property acquired before January 20, 2025, so confirm the applicable percentage with your tax advisor.
Cost segregation and bonus depreciation are different tools
A cost segregation study identifies and documents building components that belong in shorter recovery classes rather than the building’s standard 39-year class. Bonus depreciation is the deduction applied to eligible shorter-life property. In practical terms, the study establishes which components may qualify; bonus depreciation determines how quickly eligible basis may be deducted.
| Asset category | Typical recovery period | Common examples |
|---|---|---|
| Personal property | 5 or 7 years | Certain fixtures, equipment, specialty lighting and removable finishes |
| Land improvements | 15 years | Certain parking areas, sidewalks, fencing and landscaping |
| Qualified improvement property | Generally 15 years when requirements are met | Certain interior improvements to nonresidential buildings |
| Nonresidential building structure | Generally 39 years | Structural walls, roof and other core building components |
Illustrative $3 million NNN acquisition
| Purchase price | $3,000,000 |
| Less illustrative land allocation | ($600,000) |
| Illustrative depreciable basis | $2,400,000 |
| Illustrative short-life property identified by study | $600,000 |
| Potential first-year bonus depreciation | $600,000 |
This simplified example assumes the shorter-life property is eligible for 100% bonus depreciation. It does not calculate regular depreciation on remaining basis, tax savings or passive-loss availability. Actual land allocation, reclassification percentages and results vary by property and taxpayer.
Which NNN Property Components May Qualify?
Eligibility is determined component by component. The building’s use, construction and supporting documentation matter more than the property label alone.
Common candidates for shorter recovery periods
- Retail and quick-service restaurants: certain millwork, specialty electrical, decorative lighting, signage, floor coverings, equipment and site improvements may be candidates.
- Medical and dental properties: specialized plumbing, cabinetry, equipment connections and purpose-built electrical systems may warrant analysis.
- Industrial properties: process-related electrical systems, reinforced pads, specialized ventilation, equipment and land improvements may be relevant.
- Convenience stores and retail motor-fuels outlets: qualifying Section 1250 property may receive 15-year treatment when the statutory tests are met.
- Car washes: specialized equipment and certain site or building components may produce a comparatively high shorter-life allocation, but neither the entire building nor a specific percentage should be assumed to qualify without a defensible study.
Special rule for qualifying motor-fuels outlets
A convenience-store or gas-station building is not automatically 15-year property. IRS guidance describes qualifying retail motor-fuels outlets and applies tests involving petroleum-related gross revenue, floor-space use, or—in certain guidance—a facility size threshold. Review the current rules and the property’s actual operating data with a tax professional. See IRS Revenue Ruling 97-28.
What generally does not qualify for bonus depreciation?
- Land, because land is not depreciable.
- The ordinary structural portion of a nonresidential commercial building that remains 39-year property.
- Property used predominantly outside the United States and certain other excluded property.
- Property used in certain regulated utility businesses or by particular electing real-property trades or businesses, subject to the applicable rules.
Can used commercial property qualify?
Yes, certain used property can qualify. However, related-party rules, prior-use rules and the way the acquisition was structured can affect eligibility. The safest wording is not “all used NNN property qualifies,” but that a qualifying acquisition may include eligible used components.
When should a study be performed?
- At acquisition or construction: the cleanest time to establish asset classifications from the start.
- After a major renovation: new improvements may create additional reclassifiable costs.
- During ownership: a look-back study and Form 3115 may allow a taxpayer to address missed depreciation without amending every prior return.
- Before disposition: only after modeling recapture and the planned transaction with a tax advisor.
Benefits, Limitations, Recapture and 1031 Exchanges
Bonus depreciation changes timing—not total economic basis
Accelerated depreciation can move deductions into the first year, which may improve near-term after-tax cash flow. It does not make land depreciable, create additional purchase price, or eliminate the possibility of tax on a later sale. The economic benefit depends on when deductions can actually be used and how the resulting cash is deployed.
Passive-loss rules may delay the benefit
Rental losses are generally passive. A deduction can be valid yet remain suspended if the investor does not have sufficient passive income or qualify for an applicable exception. Real estate professional status, material participation and ownership structure are taxpayer-specific questions. Investors should not assume bonus depreciation will offset salary, business income, capital gains or other income without individualized advice.
State rules can differ from federal rules
States are not required to follow the federal bonus-depreciation rules. A property may produce one federal depreciation schedule and a different state schedule, adding compliance complexity and changing the projected tax benefit.
Depreciation recapture matters at sale
Accelerated deductions can increase recapture exposure when the property is sold in a taxable transaction. Different components may be subject to different recapture rules and rates. A short projected hold, a future tax-rate change or a large shorter-life allocation can materially affect the strategy’s net present value.
How bonus depreciation may interact with a 1031 exchange
A properly structured 1031 exchange may defer qualifying gain and depreciation recapture, but it does not automatically create a full new depreciable basis. Replacement-property basis generally reflects exchange calculations, including carryover basis and additional investment. Cost segregation and bonus depreciation should be modeled together with exchange basis, boot and the investor’s wider tax position.
When might a cost segregation study not be worthwhile?
- The projected tax benefit is small relative to study and compliance costs.
- The investor cannot use the losses for a long period.
- The expected hold is short and recapture offsets much of the timing benefit.
- The property contains little personal property or few land improvements.
- Documentation is insufficient for a defensible classification.
A reputable provider should begin with a feasibility analysis, explain its methodology and deliver documentation suitable for review by the taxpayer’s CPA.
Frequently Asked Questions
Is bonus depreciation 100% in 2026?
Generally, yes—for eligible property acquired and placed in service after January 19, 2025. Eligibility depends on the property class, acquisition timing and applicable exclusions.
Does an entire commercial building qualify?
Usually not. Land does not depreciate, and the ordinary structural building is generally 39-year property. A cost segregation study may identify components with recovery periods of 20 years or less.
Do NNN properties qualify for bonus depreciation?
NNN ownership does not itself determine eligibility. Qualifying components within an acquired NNN property may be eligible, depending on their tax classification and the buyer’s facts.
Can used commercial real estate qualify?
Certain used property can qualify when the statutory acquisition requirements are met, including relevant related-party and prior-use limitations.
Can bonus depreciation offset W-2 income?
Not automatically. Passive-activity rules usually restrict how rental losses can be used. A tax advisor must evaluate the investor’s material participation, real estate professional status and other circumstances.
What happens when I sell?
Previously claimed depreciation can create recapture income in a taxable sale. The amount and character depend on the assets and transaction. Model the exit before relying on a large first-year deduction.
Can bonus depreciation be combined with a 1031 exchange?
Potentially, but the available depreciable basis in the replacement property must be calculated under the exchange rules. The two strategies should be modeled together.
Can I claim missed depreciation on a property I already own?
A look-back cost segregation study and accounting-method change may allow eligible catch-up depreciation in some cases. Your CPA should determine whether Form 3115 and the related procedures apply.
