Bonus depreciation remains widely misunderstood. Investors ask the same questions: What qualifies? How do I calculate it? Can it create a loss? What about recapture? Does my state allow it?
These are not simple topics. The rules span multiple IRC sections, interact with passive activity limitations, and vary by state. Getting it wrong means leaving money on the table or, worse, facing IRS scrutiny.
This guide answers the most common bonus depreciation questions we hear from real estate investors and their CPAs. Each answer is grounded in current tax law, including the latest changes from the Big Beautiful Bill.
Whether you just acquired your first rental property or manage a portfolio of commercial buildings, understanding bonus depreciation is essential to maximizing your tax savings.
Here is what you need to know.
What is bonus depreciation?
Bonus depreciation is a federal tax incentive that allows taxpayers to deduct a large percentage of qualifying property costs in the first year the asset is placed in service. Rather than spreading deductions over many years, investors can accelerate tax savings upfront.
For real estate investors, bonus depreciation works alongside cost segregation studies to unlock significant first-year deductions. A cost segregation study identifies building components that qualify for shorter depreciation periods. Those components then become eligible for bonus depreciation.
The result: substantial tax savings in Year 1 instead of waiting decades.
How does bonus depreciation work?
When you place qualifying property in service, you apply the applicable bonus depreciation percentage to the property's adjusted depreciable basis. The basis is then reduced by the bonus amount before calculating any remaining regular depreciation.
Example: You purchase $100,000 of 5-year property eligible for 100% bonus depreciation. You deduct the full $100,000 in Year 1. No basis remains for future years.
For real estate, the process typically involves three steps:
- Complete a cost segregation study to identify qualifying assets
- Apply the bonus depreciation percentage to those assets
- Report the deduction on your tax return
The deduction is automatic unless you elect out. No IRS approval is required.
What is 100% bonus depreciation?
100% bonus depreciation allows you to deduct the entire cost of qualifying property in the first year it is placed in service. Nothing is left to depreciate in future years.
Under the Big Beautiful Bill (One Big Beautiful Bill Act), 100% bonus depreciation has been restored and made permanent for qualified property acquired after January 19, 2025. The prior phase-down schedule has been eliminated.
Current bonus depreciation rates:
For investors who delayed acquisitions during the phase-down period, the timing is now favorable. Property acquired after January 19, 2025 qualifies for full 100% bonus depreciation with no expiration date.
Note on long production period property and aircraft:
Certain property types have extended bonus depreciation deadlines under the original TCJA phase-down schedule:
- Long production period property (LPP): Property with a production period exceeding one year and costing more than $1 million
- Noncommercial aircraft (NCA): Certain aircraft not used in commercial operations
For property acquired before January 20, 2025, these asset types receive an extra year of favorable treatment:
For LPP and NCA acquired after January 19, 2025, the standard 100% rate applies under the Big Beautiful Bill.
Most real estate investors are not affected by these rules, as LPP and NCA provisions primarily apply to manufacturing equipment and aviation assets. However, investors in specialized facilities (manufacturing plants, aviation hangars) should consult their CPA.
Important: The binding contract rule
The acquisition date for bonus depreciation purposes is determined by when a written binding contract is entered into, not when the property closes or is placed in service.
This distinction matters. Property subject to a binding written contract entered into before January 20, 2025, does not qualify for the 100% rate, even if the property closes and is placed in service after that date. Instead, the phase-down rates apply based on the placed-in-service year.
Example: An investor signs a purchase agreement on January 15, 2025, and closes on March 1, 2025. Despite closing after the January 19, 2025 cutoff, the property is subject to the 40% bonus rate (2025 phase-down) because the binding contract predates the new law.
Example: An investor signs a purchase agreement on February 1, 2025, and closes on April 15, 2025. The property qualifies for 100% bonus depreciation because the binding contract was entered into after January 19, 2025.
What constitutes a binding contract?
A contract is binding if it is enforceable under state law and does not limit damages to a specified amount (such as forfeiting a deposit). Letters of intent and contracts with significant contingencies may not qualify as binding contracts.
Investors with properties under contract near the January 19, 2025 cutoff should consult their tax advisor to determine which bonus rate applies.
Transitional election: Choosing lower bonus rates
The Big Beautiful Bill includes a transitional rule allowing taxpayers to elect to use the lower phase-down rates instead of 100% bonus depreciation.
For qualified property placed in service in a taxpayer's first tax year ending after January 19, 2025, the taxpayer may elect to use the bonus depreciation rates that were in effect on January 19, 2025 (40% for 2025, 20% for 2026, etc.).
Why elect lower rates?
- Passive activity management: Spreading deductions over time may better match passive income availability
- State tax simplification: Lower federal bonus reduces state add-back amounts in decoupling states
- Income timing: Investors expecting higher tax rates in future years may prefer to defer deductions
- Loss limitation concerns: Avoiding large current-year losses that cannot be used
This election is made on a timely filed return. Consult your CPA to determine whether the transitional election benefits your specific situation.
When did 100% bonus depreciation start?
100% bonus depreciation has been available during three distinct periods:
2010-2011: The Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 introduced 100% bonus depreciation for property acquired and placed in service between September 8, 2010 and December 31, 2011.
2017-2022: The Tax Cuts and Jobs Act (TCJA) reinstated 100% bonus depreciation for property acquired and placed in service between September 27, 2017 and December 31, 2022. A phase-down began in 2023.
2025-Permanent: The Big Beautiful Bill restored 100% bonus depreciation for property acquired after January 19, 2025. This time, the provision is permanent with no scheduled phase-down.
When was bonus depreciation first introduced?
Bonus depreciation was first introduced by the Job Creation and Worker Assistance Act of 2002. It applied to property placed in service after September 10, 2001 and before January 1, 2005. The initial rate was 30%.
Congress has repeatedly extended, modified, and expanded bonus depreciation over the past two decades. The provision was designed to stimulate economic growth by encouraging businesses to invest in equipment and property.
For real estate investors, bonus depreciation became particularly valuable after the TCJA expanded eligibility to include used property and qualified improvement property. Today, when combined with cost segregation services, bonus depreciation remains one of the most powerful tax planning tools available.
What qualifies for bonus depreciation?
To qualify for bonus depreciation, property must meet specific IRS requirements. The core criteria include:
- MACRS property with a recovery period of 20 years or less. This includes 5-year, 7-year, and 15-year property commonly identified in cost segregation studies.
- Computer software as defined and depreciated under IRC § 167(f)(1).
- Water utility property as defined in IRC § 168(e)(5).
- Qualified improvement property (QIP). Interior improvements to nonresidential buildings now qualify as 15-year property.
- Specified plants. Trees and vines bearing fruits or nuts qualify if the taxpayer elects to apply bonus depreciation in the year of planting.
For property acquired after September 27, 2017, the original use requirement was relaxed. Used property now qualifies as long as:
- The taxpayer did not previously use the property
- The property was not acquired from a related party
- The property was not acquired in certain tax-free transactions
This change opened bonus depreciation to a much larger pool of real estate investments.
What assets qualify for bonus depreciation?
Common qualifying assets include:
Personal Property (5-year and 7-year):
5-year property:
- Computers and peripherals
- Office equipment (copiers, printers)
- Vehicles
- Appliances
- Carpeting and flooring
- Window treatments
- Decorative lighting
- Security systems
7-year property:
- Office furniture (desks, chairs, filing cabinets)
- Fixtures not inherently permanent
- Agricultural machinery and equipment
- Motorsports entertainment complex property
- Certain manufacturing equipment
- Property without a specific class life
Land Improvements (15-year):
- Parking lots and driveways
- Sidewalks and curbing
- Landscaping
- Fencing
- Signage
- Outdoor lighting
- Retaining walls
Qualified Improvement Property (15-year):
- Interior renovations to nonresidential buildings
- Upgraded finishes
- Interior walls (non-structural)
- Ceilings and lighting systems
What does NOT qualify:
- Buildings themselves (27.5-year residential or 39-year commercial property)
- Land (land is not depreciable)
- Property required to use the Alternative Depreciation System (ADS) in most cases
- Property used predominantly outside the United States
Understanding land value is important because land must be separated from the building cost before depreciation calculations begin. Land is never depreciable, regardless of bonus rules.
What property qualifies for bonus depreciation?
Property qualifies when it meets three tests:
1. Recovery Period Test The property must have a MACRS recovery period of 20 years or less. This automatically excludes building structures but includes most components identified through cost segregation.
2. Acquisition Date Test For 100% bonus depreciation under the Big Beautiful Bill, the property must be acquired after January 19, 2025. For property acquired earlier, the applicable phase-down rate applies based on when the property was placed in service.
3. Placed-in-Service Test The property must be placed in service during the tax year for which the deduction is claimed. Property under construction does not qualify until it is ready and available for its intended use.
Understanding the difference: Acquisition date vs. placed-in-service date
These two dates serve different purposes and should not be confused:
Acquisition date: Determines which bonus depreciation rate applies. For 100% bonus depreciation under the Big Beautiful Bill, property must be acquired after January 19, 2025. Acquisition generally occurs when a binding written contract is signed.
Placed-in-service date: Determines when you claim the deduction. Property is placed in service when it is ready and available for its intended use. This is the tax year in which depreciation begins.
Why this matters:
Property could be acquired after January 19, 2025, but not placed in service until 2026. The 100% rate applies (based on acquisition date), but the deduction is claimed in 2026 (based on placed-in-service date).
Example: An investor signs a purchase contract on March 1, 2025, for a property under construction. The property is completed and placed in service on February 15, 2026. The investor qualifies for 100% bonus depreciation (acquired after January 19, 2025) but claims the deduction on their 2026 tax return (year placed in service).
A professional cost segregation study is essential to properly identify and document qualifying property. The study involves detailed analysis, often including a site visit, to ensure assets are correctly classified and meet IRS requirements.
What is qualified property for bonus depreciation?
The IRS defines "qualified property" in IRC § 168(k)(2)(A). The definition requires taxpayers to separately identify each asset to determine eligibility. You cannot assume an entire project qualifies simply because some components do.
This is why cost segregation matters. Without a detailed study, investors typically depreciate their entire building over 27.5 or 39 years. They miss the opportunity to reclassify 15% to 40% of building costs into shorter-life categories that qualify for bonus depreciation.
Example: An investor purchases a $2 million apartment building. Without cost segregation, the entire building (minus land value) depreciates over 27.5 years. With a cost segregation study, $400,000 is reclassified as 5-year and 15-year property. At 100% bonus depreciation, the investor deducts $400,000 in Year 1.
At a 37% tax rate, that represents $148,000 in immediate tax savings.
What is eligible for bonus depreciation?
Eligibility depends on asset classification and timing. Here is a summary:
Key point: Eligibility is determined at the asset level, not the property level. A single real estate investment may contain dozens of individual assets, each with its own classification.
R.E. Cost Seg specializes in identifying these assets through engineering-based cost segregation studies. The process ensures every qualifying component is properly classified and documented to support bonus depreciation claims.
Can you take bonus depreciation on rental property?
Yes. Rental property owners can claim bonus depreciation on qualifying components of their investment.
The building structure itself does not qualify. Residential rental buildings depreciate over 27.5 years. Commercial buildings depreciate over 39 years. Neither recovery period meets the 20-year-or-less requirement for bonus depreciation.
However, buildings contain many components that do qualify. These include personal property (appliances, carpeting, fixtures) and land improvements (parking lots, landscaping, fencing). A cost segregation study identifies these components and reclassifies them into shorter recovery periods.
Typical reclassification results:
Once reclassified, these assets qualify for bonus depreciation. For property acquired after January 19, 2025, that means 100% of the reclassified costs can be deducted in Year 1.
Example: An investor purchases a $1.5 million rental property. A cost segregation study reclassifies $300,000 into 5-year and 15-year property. With 100% bonus depreciation, the investor claims a $300,000 deduction in the first year.
At a combined federal and state tax rate of 40%, the immediate tax savings equals $120,000.
What is bonus depreciation in real estate?
In real estate, bonus depreciation is the mechanism that transforms cost segregation findings into immediate tax savings.
Here is how the process works:
Step 1: Acquire or improve property. The investor purchases a building or completes qualifying improvements.
Step 2: Complete a cost segregation study. Engineers and tax professionals analyze the property to identify components with shorter recovery periods. This typically involves reviewing construction documents, analyzing costs, and conducting a site visit to verify asset classifications.
Step 3: Apply bonus depreciation. Qualifying 5-year, 7-year, and 15-year assets receive the applicable bonus depreciation percentage. For property acquired after January 19, 2025, this is 100%.
Step 4: Claim the deduction. The total bonus depreciation is reported on the investor's tax return. For properties placed in service in prior years, Form 3115 is used to claim catch-up depreciation without amending previous returns.
The investor benefit: Cash that would have flowed to the IRS over decades is retained in Year 1. This capital can be reinvested, used to acquire additional properties, or applied to debt reduction.
What is cost segregation and bonus depreciation?
Cost segregation and bonus depreciation are two distinct tax concepts that work together to accelerate real estate deductions.
Cost segregation is an engineering-based study that identifies building components qualifying for shorter depreciation recovery periods. The study reclassifies assets from 27.5-year or 39-year property into 5-year, 7-year, or 15-year categories.
Bonus depreciation is the tax provision allowing first-year deductions on qualifying property. Currently, 100% bonus depreciation applies to property acquired after January 19, 2025.
How they combine:
Without cost segregation, an investor depreciates their entire building slowly. A $1 million commercial building (excluding land value) would generate approximately $25,641 in annual depreciation over 39 years.
With cost segregation, assume $250,000 is reclassified into bonus-eligible categories. The investor now deducts $250,000 in Year 1, plus regular depreciation on the remaining $750,000.
The difference in first-year deductions: $250,000 versus $25,641.
Cost segregation identifies the opportunity. Bonus depreciation delivers the accelerated tax benefit.
Can you take bonus depreciation on leasehold improvements?
Yes, through the Qualified Improvement Property (QIP) rules. However, specific requirements must be met.
QIP is defined as any improvement to the interior portion of a nonresidential building made by the taxpayer after the building was first placed in service. QIP qualifies as 15-year property, making it eligible for bonus depreciation.
QIP requirements:
- The improvement must be to the interior of a nonresidential building
- The improvement must be made after the building was originally placed in service
- The taxpayer must make the improvement (critical requirement)
QIP exclusions:
- Building enlargements
- Elevators and escalators
- Internal structural framework modifications
- Improvements to residential property
Critical limitation: QIP cannot be purchased
QIP must be made by the taxpayer, not acquired through a building purchase. If you purchase a building with existing tenant improvements or prior renovations, those improvements do not qualify as QIP for your tax purposes.
Example of what does NOT qualify: An investor purchases an office building for $2 million. The previous owner spent $300,000 on interior renovations two years ago. The investor cannot claim the $300,000 in prior renovations as QIP eligible for bonus depreciation. Those improvements were made by the previous owner, not the purchasing taxpayer.
Example of what DOES qualify: After purchasing the building, the investor spends $150,000 on new interior improvements. These improvements qualify as QIP because the taxpayer made them after the building was placed in service.
History: The Tax Cuts and Jobs Act of 2017 intended to make QIP 15-year property eligible for bonus depreciation. A drafting error initially classified QIP as 39-year property. The CARES Act of 2020 corrected this mistake, retroactively changing QIP to 15-year property.
For tenants making leasehold improvements:
Tenants who make qualifying interior improvements to leased nonresidential space can claim QIP treatment if:
- The improvement meets all QIP requirements
- The tenant has the tax basis in the improvement (not reimbursed by landlord)
- The lease does not require the landlord to make the improvements
Example: A restaurant tenant invests $200,000 in interior buildout of a leased commercial space. The tenant pays for the improvements and owns them for tax purposes. The improvements qualify as QIP. With 100% bonus depreciation, the tenant deducts the full $200,000 in Year 1.
Cost segregation and existing improvements:
While purchased improvements do not qualify as QIP, a cost segregation study can still identify personal property components (5-year and 7-year assets) within the building that qualify for bonus depreciation under different rules. Items like carpeting, appliances, decorative fixtures, and certain electrical components may qualify even if they were installed by a prior owner.
The distinction matters: QIP (15-year property) requires the taxpayer to make the improvement. Personal property (5-year and 7-year) can be acquired with the building and still qualify for bonus depreciation as used property under the TCJA rules.
How to calculate bonus depreciation?
The calculation is straightforward once you identify qualifying property.
Formula:
Bonus Depreciation = Qualified Property Cost × Applicable Bonus Percentage
Step-by-step process:
Step 1: Determine the depreciable basis. Start with the purchase price. Subtract the land value (land is not depreciable). The remaining amount is your depreciable basis.
Step 2: Identify qualifying property. Through a cost segregation study, separate the depreciable basis into asset categories. Identify which assets have recovery periods of 20 years or less.
Step 3: Confirm acquisition and placed-in-service dates. Verify when the property was acquired and placed in service. This determines the applicable bonus percentage.
Step 4: Apply the bonus percentage. Multiply the qualifying property cost by the applicable rate. For property acquired after January 19, 2025, the rate is 100%.
Step 5: Reduce the basis. Subtract the bonus depreciation from the asset's basis before calculating any remaining regular depreciation.
Calculation example:
An investor purchases a $1.2 million apartment building. Land value is $200,000. The depreciable basis is $1 million.
A cost segregation study identifies:
- $150,000 in 5-year property (appliances, carpeting, fixtures)
- $100,000 in 15-year property (parking lot, landscaping, fencing)
- $750,000 in 27.5-year property (building structure)
Bonus depreciation calculation (at 100%):
- 5-year property: $150,000 × 100% = $150,000
- 15-year property: $100,000 × 100% = $100,000
- 27.5-year property: $0 (does not qualify)
Total first-year bonus depreciation: $250,000
The remaining $750,000 in building structure depreciates normally over 27.5 years, generating an additional $27,273 in Year 1 depreciation.
Total Year 1 depreciation: $277,273
Without cost segregation, the investor would have claimed only $36,364 in Year 1 depreciation ($1 million ÷ 27.5 years).
How to use bonus depreciation?
Using bonus depreciation involves proper planning, documentation, and tax reporting.
For newly acquired property:
- Complete a cost segregation study. Engage a qualified provider like R.E. Cost Seg to analyze your property. The study identifies qualifying assets and provides documentation supporting your deductions.
- Coordinate with your CPA. Share the cost segregation report with your tax preparer. The report includes specific asset classifications and depreciation schedules.
- Report on Form 4562. Your CPA includes the bonus depreciation on your tax return. No special election or IRS approval is required.
- Maintain documentation. Keep the cost segregation study and supporting records. The IRS may request documentation during an audit.
For property placed in service in prior years:
Investors who missed cost segregation on existing properties can still benefit. The IRS allows a "catch-up" adjustment through Form 3115 (Application for Change in Accounting Method).
This approach offers significant advantages:
- No amended returns required
- Claim all missed depreciation in the current tax year
- Automatic IRS consent for this accounting method change
Important: While amended returns are not required, Form 3115 is a complex filing with specific requirements. The form must be filed with your current-year return and a copy sent to the IRS National Office in Ogden, Utah. Errors in Form 3115 preparation can delay processing or trigger IRS inquiries.
Key requirements include:
- Identifying the specific change being made (change number)
- Calculating the Section 481(a) adjustment accurately
- Meeting filing deadlines and procedural requirements
- Proper attachment to the tax return
We recommend working with a CPA experienced in accounting method changes to ensure proper Form 3115 preparation. R.E. Cost Seg provides detailed instructions and works directly with your tax preparer to facilitate proper filing.
Example: An investor purchased a rental property in 2021 and depreciated it using the standard 27.5-year method. In 2025, they complete a cost segregation study. Using Form 3115, they claim all missed accelerated depreciation as a single adjustment in 2025.
The catch-up adjustment, called a Section 481(a) adjustment, can generate substantial tax savings in one year.
Where does bonus depreciation go on Form 4562?
Bonus depreciation is reported in Part II of Form 4562, titled "Special Depreciation Allowance and Other Depreciation."
Specific line items:
- Line 14: Special depreciation allowance for qualified property (other than listed property)
- Line 25: Special depreciation allowance for listed property (vehicles, computers used for business)
Reporting requirements:
For most bonus depreciation claims, no additional statement is required. The deduction flows through Form 4562 to Schedule E (rental properties) or the appropriate business schedule.
If electing out of bonus depreciation:
Taxpayers who choose to forgo bonus depreciation must attach a statement to their timely filed return. The statement must identify the class of property and the tax year for which the election applies.
For Form 3115 catch-up claims:
When claiming catch-up depreciation on existing property, Form 3115 is filed with the current-year return. The Section 481(a) adjustment appears on the appropriate income schedule, and Form 4562 reflects the new depreciation method going forward.
Record-keeping tip: Maintain your cost segregation study, Form 4562, and any attached statements together. These documents support your depreciation deductions if the IRS requests verification.
When to use bonus depreciation?
Bonus depreciation is most valuable in specific situations. Understanding when to use it helps maximize tax benefits.
Use bonus depreciation when:
You acquire qualifying property. Any time you purchase or construct property containing 5-year, 7-year, or 15-year assets, bonus depreciation applies automatically.
You want to maximize first-year deductions. If you have taxable income to offset, bonus depreciation converts future deductions into immediate tax savings.
You qualify for non-passive treatment. Investors with Real Estate Professional Status can use depreciation losses against W-2 and other active income. The STR loophole also allows short-term rental owners who materially participate to claim non-passive treatment.
You have catch-up opportunities. For properties placed in service in prior years, a cost segregation study combined with Form 3115 captures all missed depreciation in a single year.
You plan to hold the property long-term. The longer you hold, the more valuable the time value of money becomes. A dollar saved today is worth more than a dollar paid in taxes years from now.
Consider alternatives when:
You expect significantly higher tax rates in future years. If your income will increase substantially, deferring deductions to higher-rate years may produce greater tax savings.
You need to preserve losses for passive activity purposes. Passive investors may want to spread deductions over time to match them against passive income.
Your state decouples from federal bonus rules. States like California and New York require add-backs for bonus depreciation. Electing out may simplify state tax compliance.
You anticipate a short holding period. If you plan to sell soon, accelerated depreciation increases recapture exposure. However, a 1031 exchange can defer recapture indefinitely.
Can bonus depreciation create a loss?
Yes. Unlike Section 179, bonus depreciation can create or increase a net operating loss (NOL).
There is no dollar limit on the amount of bonus depreciation a taxpayer may claim in any given year. If bonus depreciation exceeds your taxable income, the result is a tax loss.
Example: An investor has $150,000 in rental income and $80,000 in operating expenses. Net rental income before depreciation is $70,000. A cost segregation study generates $200,000 in first-year bonus depreciation.
Result: $70,000 income minus $200,000 depreciation equals a $130,000 loss.
However, using that loss depends on several factors.
Passive activity rules:
For most rental property owners, rental income is classified as passive. Losses from passive activities can only offset passive income. They cannot offset W-2 wages, business income, or investment income unless an exception applies.
Exceptions that allow non-passive treatment include:
- Real Estate Professional Status. Taxpayers who qualify as a Real Estate Professional can treat rental losses as non-passive. This requires meeting two tests: (1) more than 750 hours annually in real property trades or businesses, and (2) more time spent in real estate than any other profession.
- Short-term rental exception. Owners of short-term rentals (average guest stay of 7 days or less) who materially participate in the rental activity can claim non-passive treatment. This is sometimes called the STR loophole.
- Material participation in rental activity. Real Estate Professionals must also materially participate in each rental activity to deduct losses against active income. Grouping elections can help satisfy this requirement.
At-risk rules:
Losses are also limited to the amount you have "at risk" in the activity. At-risk amounts generally include:
- Cash invested
- Adjusted basis of property contributed
- Amounts borrowed for which you are personally liable
- Qualified nonrecourse financing (for real estate only)
You cannot deduct losses exceeding your at-risk amount. Excess losses are suspended and carried forward.
Net operating loss treatment:
If bonus depreciation creates an NOL, current rules allow:
- Indefinite carryforward. NOLs can be carried forward to future years with no expiration.
- 80% limitation. NOLs can only offset 80% of taxable income in carryforward years. The remaining 20% remains taxable.
- No carryback. Under current law, NOLs generally cannot be carried back to prior years (with limited exceptions for certain farming losses).
Planning considerations:
Creating a large loss through bonus depreciation requires strategic planning. Consider these factors:
Current year benefit versus future use. If you cannot use the loss currently due to passive activity limitations, it carries forward. Future passive income (from rentals, K-1 distributions, or property sales) can absorb suspended losses.
Impact on basis. Depreciation reduces your adjusted basis in the property. Lower basis means higher gain (or lower loss) when you sell.
Recapture exposure. All depreciation claimed, including bonus depreciation, is subject to recapture upon sale. However, a 1031 exchange defers recapture indefinitely.
State tax implications. States that decouple from federal bonus depreciation will not recognize the loss for state purposes. You may have a federal loss but state taxable income.
Example with passive activity limitation:
An investor with no Real Estate Professional Status earns $300,000 in W-2 income and $50,000 in rental income. A cost segregation study generates $150,000 in bonus depreciation.
- Rental loss: $50,000 income minus $150,000 depreciation = ($100,000) loss
- Passive loss limitation: The $100,000 loss can only offset passive income
- Usable loss in current year: $50,000 (offsets the rental income)
- Suspended loss carried forward: $50,000
The suspended $50,000 carries forward to future years when the investor has additional passive income or sells the property.
Example with Real Estate Professional Status:
Same facts, but the investor qualifies as a Real Estate Professional and materially participates in the rental activity.
- Rental loss: ($100,000)
- Passive loss limitation: Does not apply (non-passive treatment)
- Usable loss: Full $100,000 offsets W-2 income
At a 37% tax rate, this generates $37,000 in tax savings.
The bottom line:
Bonus depreciation can absolutely create a loss. The ability to use that loss against other income depends on your tax situation. Investors seeking to offset W-2 or business income should evaluate Real Estate Professional Status or the short-term rental exception.
Working with a qualified CPA ensures proper application of passive activity rules and maximizes the benefit of bonus depreciation losses.
What is the difference between bonus depreciation and Section 179?
Bonus depreciation and Section 179 are both first-year depreciation incentives, but they operate under different rules. Understanding these differences helps investors choose the right strategy.
Key differences:
Dollar limits:
Bonus depreciation has no annual dollar limit. You can claim 100% of qualifying property costs regardless of the total amount.
Section 179 has an annual deduction limit of $1,250,000 for 2025. This limit begins phasing out dollar-for-dollar when total qualifying property placed in service exceeds $3,130,000. At $4,380,000 in qualifying property, the Section 179 deduction phases out completely.
Loss limitations:
This is one of the most significant differences. Bonus depreciation can create or increase a net operating loss. Section 179 cannot.
Section 179 deductions are limited to taxable income from all active trades or businesses. If your business income is $100,000, your Section 179 deduction cannot exceed $100,000 (even if you have $500,000 in qualifying property). Unused Section 179 amounts carry forward to future years.
Bonus depreciation has no such limitation. It can reduce taxable income below zero, creating a loss that carries forward under NOL rules.
Election requirements:
Bonus depreciation applies automatically to all qualifying property unless you elect out. No affirmative election is needed to claim it.
Section 179 requires an affirmative election. You must specifically identify the property and the amount you are expensing on Form 4562.
Eligible taxpayers:
Bonus depreciation is available to all taxpayers, including individuals, corporations, partnerships, S corporations, trusts, and estates.
Section 179 is not available to estates and trusts. This limitation makes bonus depreciation particularly valuable for trust-owned real estate.
Order of application:
When both provisions apply to the same property, Section 179 is applied first. Bonus depreciation then applies to the remaining basis.
Example: You purchase $200,000 of qualifying equipment. You elect $100,000 of Section 179. The remaining $100,000 basis is eligible for bonus depreciation. At 100% bonus, you deduct the remaining $100,000. Total first-year deduction: $200,000.
Is bonus depreciation the same as Section 179?
No. Despite both providing accelerated first-year deductions, bonus depreciation and Section 179 are separate tax provisions with distinct rules.
Common misconceptions:
Misconception 1: "They're interchangeable." Reality: Each has unique eligibility rules, limits, and applications. Choosing between them (or using both) requires analysis of your specific situation.
Misconception 2: "I have to choose one or the other." Reality: You can use both on the same property. Section 179 applies first, then bonus depreciation applies to any remaining basis.
Misconception 3: "Bonus depreciation is better because there's no limit." Reality: It depends. Section 179 allows deductions on some property types that do not qualify for bonus depreciation. Section 179 also allows more flexibility in choosing how much to deduct.
When Section 179 may be preferred:
- You want to control the amount of first-year deduction (partial expensing)
- The property qualifies for Section 179 but not bonus depreciation
- You want to avoid creating a loss
When bonus depreciation may be preferred:
- You want to maximize first-year deductions without limits
- You are willing to create a loss for NOL carryforward
- The taxpayer is a trust or estate (Section 179 unavailable)
- You prefer automatic treatment without election requirements
Strategic combination:
Many investors use both provisions strategically. For example:
- Elect Section 179 on specific assets up to the taxable income limit
- Apply bonus depreciation to remaining qualifying property
- Create a loss through bonus depreciation if beneficial
This approach maximizes deductions while maintaining flexibility.
Is bonus depreciation subject to recapture?
Yes. Bonus depreciation is treated as depreciation for all tax purposes, including recapture.
When you sell a property at a gain, the IRS requires you to "recapture" previously claimed depreciation. This means a portion of your gain is taxed at higher rates than standard capital gains rates.
How recapture works:
Depreciation reduces your adjusted basis in the property. When you sell, gain is calculated as the difference between the sales price and your adjusted basis. The lower your basis, the higher your gain.
The IRS divides this gain into categories based on property type and the type of depreciation claimed.
Recapture rules by property type:
Section 1245 property (personal property):
This includes 5-year and 7-year property identified in cost segregation studies: appliances, carpeting, fixtures, furniture, and equipment.
All depreciation claimed on Section 1245 property, including bonus depreciation, is recaptured as ordinary income at your marginal tax rate (up to 37%).
Section 1250 property (real property improvements):
This includes 15-year land improvements, qualified improvement property, and building structures.
Section 1250 recapture has two components that investors should understand:
Component 1: Additional depreciation (ordinary income recapture)
For Section 1250 property, the IRS treats bonus depreciation as an accelerated depreciation method. The difference between the bonus depreciation claimed and the straight-line depreciation that would have been claimed is considered "additional depreciation."
Under IRC § 1250(a), this additional depreciation may be recaptured as ordinary income (up to 37%) rather than at the 25% rate.
Example: An investor claims $100,000 in bonus depreciation on 15-year land improvements in Year 1. Straight-line depreciation would have been $6,667 in Year 1. The "additional depreciation" is $93,333 ($100,000 - $6,667). If the property is sold at a gain, this $93,333 may be subject to ordinary income recapture.
Component 2: Unrecaptured Section 1250 gain (25% rate)
After accounting for any ordinary income recapture, remaining depreciation on Section 1250 property is taxed at a maximum rate of 25%. This is commonly called "unrecaptured Section 1250 gain."
Practical impact:
The distinction between these two components affects the tax rate on depreciation recapture:
Planning note: Despite the potential for ordinary income recapture on the "additional depreciation" component, the time value of money and deferral strategies (especially 1031 exchanges) typically still favor claiming bonus depreciation. Consult your CPA to model the specific impact for your situation.
Does recapture eliminate the benefit of bonus depreciation?
No. Bonus depreciation remains beneficial for three reasons.
Reason 1: Time value of money.
A dollar saved today is worth more than a dollar paid in taxes years later. If you claim $100,000 in bonus depreciation today and pay recapture in 10 years, you have had use of that money for a decade. Invested wisely, those funds generate additional returns.
Example: An investor saves $37,000 in taxes through bonus depreciation (at 37% rate). They invest the savings at 7% annual return. After 10 years, the investment grows to approximately $72,750. Even after paying recapture tax, they retain significantly more than if they had never claimed bonus depreciation.
Reason 2: Rate differential.
Bonus depreciation offsets income at your current marginal rate, which may be as high as 37%. Unrecaptured Section 1250 gain is capped at 25%. This spread creates permanent tax savings for the portion taxed at the lower recapture rate.
Reason 3: Deferral strategies exist.
Investors can defer recapture indefinitely through a 1031 exchange. By exchanging into like-kind replacement property, both capital gains and depreciation recapture are deferred. Many investors continue exchanging throughout their lifetime, and heirs receive a stepped-up basis at death, potentially eliminating recapture entirely.
Planning strategies to manage recapture
Strategy 1: 1031 exchange.
A properly structured 1031 exchange defers all gain, including depreciation recapture. The deferred depreciation carries over to the replacement property, reducing its basis. Recapture is only triggered when you eventually sell without exchanging.
Many investors use serial 1031 exchanges, continuously deferring gain and recapture while building wealth through larger properties.
Strategy 2: Installment sale.
Selling property through an installment sale spreads gain recognition over multiple years. Recapture is recognized proportionally as payments are received. This can keep you in lower tax brackets and reduce overall tax liability.
Note: Depreciation recapture on Section 1245 property must be recognized in the year of sale, regardless of installment treatment. Only Section 1250 recapture and capital gain can be spread.
Strategy 3: Opportunity Zone investment.
Reinvesting capital gains into a Qualified Opportunity Zone Fund defers gain recognition. While this does not eliminate recapture, it provides deferral and potential reduction of the gain if the investment is held long enough.
Strategy 4: Charitable giving.
Donating appreciated property to a qualified charity may allow you to avoid both capital gains and recapture. You receive a charitable deduction for the fair market value of the property. Consult with your tax advisor on specific requirements and limitations.
Strategy 5: Hold until death.
Under current law, heirs receive a stepped-up basis in inherited property. This eliminates all built-in gain, including depreciation recapture. Holding property until death can be the most tax-efficient exit strategy for some investors.
Recapture and cost segregation: The full picture
Some investors hesitate to pursue cost segregation because of recapture concerns. This hesitation is often misplaced.
Consider the math:
An investor has two options:
Option A: No cost segregation.
- Annual depreciation: $36,364 (straight-line over 27.5 years)
- Year 1 tax savings (at 37%): $13,455
Option B: Cost segregation with bonus depreciation.
- Year 1 depreciation: $277,273 (including $250,000 bonus)
- Year 1 tax savings (at 37%): $102,591
Difference in Year 1 tax savings: $89,136
Even accounting for higher recapture upon sale, Option B generates significantly more present-value benefit. The investor has $89,136 more cash in Year 1 to reinvest, pay down debt, or acquire additional properties.
The bottom line:
Recapture is a factor to consider, not a reason to avoid bonus depreciation. The tax savings today, rate differential, and available deferral strategies typically make bonus depreciation the superior choice.
Work with your CPA to model the full tax impact, including projected holding period and exit strategy. Understanding recapture upfront allows you to plan accordingly and maximize after-tax wealth.
Can you elect out of bonus depreciation?
Yes. Taxpayers may elect to forgo bonus depreciation for any class of property placed in service during the tax year.
This election is made on a class-by-class basis. You cannot selectively elect out for individual assets within a class. If you elect out for 5-year property, the election applies to all 5-year property placed in service that year.
How to make the election:
Attach a statement to your timely filed federal tax return (including extensions) for the year the property is placed in service. The statement must specify:
- The class of property for which you are electing out (e.g., "all 5-year property" or "all 15-year property")
- The tax year to which the election applies
No specific form is required. A clear written statement attached to Form 4562 is sufficient.
Revoking the election:
Once made, the election to forgo bonus depreciation can only be revoked with IRS consent. This generally requires a private letter ruling, which involves fees and processing time.
However, Treasury Regulations provide automatic relief in certain situations. Under Treas. Reg. § 301.9100-2(b), taxpayers may revoke the election within six months of the original due date (excluding extensions) by filing an amended return with "Filed pursuant to section 301.9100-2" written at the top.
Reasons to elect out:
Reason 1: Preserve deductions for higher-rate years.
If you expect to be in a significantly higher tax bracket in future years, spreading depreciation may produce greater tax savings. Deductions at a 37% rate are worth more than deductions at a 24% rate.
Example: A medical resident earns $60,000 in 2025 but expects to earn $400,000 by 2028. Electing out of bonus depreciation preserves deductions for higher-income years when the tax benefit is greater.
Reason 2: Manage passive activity limitations.
Passive investors can only use rental losses against passive income. Large bonus depreciation deductions may create suspended losses that carry forward indefinitely.
If you have limited passive income to absorb losses, electing out spreads deductions over time. This matches deductions to income more evenly, reducing suspended loss balances.
Reason 3: State tax simplification.
In states that decouple from federal bonus depreciation, electing out eliminates the need for separate depreciation schedules. Federal and state depreciation match, simplifying compliance and recordkeeping.
Reason 4: Avoid excess recapture.
If you plan to sell the property in the near term, large bonus depreciation increases recapture exposure. Electing out reduces first-year depreciation and preserves basis, potentially lowering gain on sale.
Reason 5: Tax loss harvesting strategy.
Some investors prefer to time losses strategically. Electing out in certain years and claiming bonus depreciation in others allows precise tax planning across multiple properties and tax years.
Reasons NOT to elect out:
Time value of money: A dollar saved today is worth more than a dollar saved tomorrow. Accelerating deductions puts cash in your pocket sooner.
Rate differential: Bonus depreciation offsets income at ordinary rates (up to 37%). Recapture on real property is capped at 25%. This spread creates permanent tax savings.
Reinvestment opportunity: Tax savings can be reinvested in additional properties, accelerating wealth building.
1031 exchange planning: If you plan to exchange rather than sell, recapture is deferred indefinitely. The downside of accelerated depreciation is eliminated.
Election mechanics by entity type:
Individuals and sole proprietors: Attach the election statement to Form 1040 and Form 4562.
Partnerships and S corporations: The election is made at the entity level, not by individual partners or shareholders. Attach the statement to the partnership or S corporation return (Form 1065 or 1120-S).
C corporations: Attach the statement to Form 1120.
Trusts and estates: Attach the statement to Form 1041 and Form 4562.
Can a trust take bonus depreciation?
Yes. Trusts and estates are fully eligible to claim bonus depreciation on qualifying property.
This is an important distinction from Section 179 expensing. Trusts and estates cannot claim Section 179 deductions under IRC § 179(d)(4). However, no such limitation exists for bonus depreciation.
Why this matters:
Many real estate investors hold property in trusts for estate planning, asset protection, or privacy purposes. Common structures include:
- Revocable living trusts
- Irrevocable trusts
- Qualified Personal Residence Trusts (QPRTs)
- Dynasty trusts
- Land trusts
Property held in these structures remains eligible for cost segregation and bonus depreciation. The trust claims the deduction, and it flows through to beneficiaries or remains at the trust level depending on the trust's distributable net income (DNI).
Trust taxation basics:
Trusts and estates are separate taxpayers with their own tax brackets. However, trust tax brackets are highly compressed compared to individual brackets. Trusts reach the top 37% federal tax bracket at a much lower income threshold than individuals.
For 2024, trusts reached the 37% bracket at $14,450 of taxable income. The 2025 threshold is adjusted annually for inflation. Check current IRS guidance for the applicable year.
This compressed rate structure makes bonus depreciation particularly valuable for trusts. Large depreciation deductions can eliminate trust-level taxable income entirely, avoiding the top bracket.
Grantor trusts:
If a trust is a "grantor trust" for tax purposes, all income and deductions are reported on the grantor's individual return. The trust is disregarded for income tax purposes.
In this case, bonus depreciation flows directly to the grantor. The grantor claims the deduction on their Form 1040 as if they owned the property individually.
Non-grantor trusts:
For non-grantor trusts, the trust is a separate taxpayer. Bonus depreciation is claimed on Form 1041 (U.S. Income Tax Return for Estates and Trusts).
If the trust distributes income to beneficiaries, depreciation deductions may be allocated between the trust and beneficiaries based on the trust's accounting income. Consult with a tax professional on specific allocation rules.
Example:
A family irrevocable trust owns a $2 million apartment building. The trust completes a cost segregation study identifying $450,000 in 5-year and 15-year property.
With 100% bonus depreciation, the trust claims a $450,000 first-year deduction. This deduction offsets rental income and may create a loss that passes through to beneficiaries (subject to passive activity rules at the beneficiary level).
Without bonus depreciation availability, the trust would be limited to straight-line depreciation of approximately $54,545 per year ($1.5 million building basis ÷ 27.5 years).
Estate planning benefits:
Bonus depreciation enhances several estate planning strategies:
Installment sales to grantor trusts: A grantor sells appreciated property to an intentionally defective grantor trust (IDGT) in exchange for an installment note. The trust claims bonus depreciation, generating deductions that offset installment payments. This can result in significant wealth transfer with minimal gift tax exposure.
Charitable remainder trusts (CRTs): While CRTs are tax-exempt, the remainder beneficiaries (often family members) eventually receive trust assets. Maximizing depreciation during the trust term preserves asset value.
Qualified Subchapter S Trusts (QSSTs) and Electing Small Business Trusts (ESBTs): These trusts can hold S corporation stock. If the S corporation owns real estate, bonus depreciation passes through to the trust.
Key planning considerations:
Passive activity rules still apply. Trusts are subject to passive activity limitations. Rental losses are generally passive and can only offset passive income at the trust or beneficiary level.
Material participation is difficult. Trusts cannot materially participate in activities in the same manner as individuals. This limits the ability to claim non-passive treatment for rental activities.
Real Estate Professional Status is unavailable. Only individuals can qualify as Real Estate Professionals. Trusts cannot achieve REPS designation.
At-risk rules apply. Trusts are subject to at-risk limitations, restricting losses to amounts the trust has at risk in the activity.
The bottom line:
Trusts and estates benefit significantly from bonus depreciation. Unlike Section 179, no statutory limitation prevents trusts from claiming this valuable deduction.
If you hold real estate in a trust structure, cost segregation and bonus depreciation remain available. Work with your estate planning attorney and CPA to coordinate depreciation strategy with overall trust objectives.
