Cost Segregation for Rental Property: Tax Benefits, 100 Percent Bonus Depreciation, and Recapture
Cost segregation can substantially accelerate depreciation deductions for rental property and commercial real estate, particularly under the current federal rules allowing 100 percent bonus depreciation for certain qualified property acquired and placed in service after January 19, 2025.
The potential deduction, however, is only the beginning of the analysis.
A cost segregation study changes the timing and, in some cases, the tax character of depreciation by identifying assets that can properly be depreciated over shorter recovery periods instead of being included entirely in the building.
Whether the strategy actually creates a meaningful tax benefit depends on several additional factors, including whether the taxpayer can currently use the deductions, passive activity loss limitations, real estate professional status, short term rental rules, the expected holding period, future depreciation recapture, California depreciation differences, and the quality of the underlying study.
For broader guidance on depreciation, passive losses, property dispositions, and other investor tax issues, see my Real Estate Tax Planning resource page.
Key Tax Takeaways
- Cost segregation identifies separate assets within a real estate investment and assigns the appropriate federal tax recovery periods.
- Residential rental buildings are generally depreciated over 27.5 years and nonresidential real property generally over 39 years.
- A properly supported study can identify qualifying 5 year, 7 year, and 15 year property within the overall investment.
- Under current federal law, certain qualified property acquired and placed in service after January 19, 2025 can qualify for 100 percent bonus depreciation.
- Qualified bonus depreciation property generally includes eligible MACRS property with a recovery period of 20 years or less.
- Certain used property can qualify for federal bonus depreciation when the statutory acquisition requirements are satisfied.
- The 27.5 year or 39 year building itself does not qualify for bonus depreciation merely because a cost segregation study was performed.
- Land is not depreciable and must be separated from depreciable property.
- Accelerated depreciation can create suspended passive losses rather than an immediate tax benefit.
- A taxpayer can often perform a cost segregation study after a property has already been placed in service.
- A prior year cost segregation adjustment can require Form 3115 and a Section 481(a) adjustment rather than simply applying the current bonus depreciation percentage.
- Cost segregation can increase future Section 1245 ordinary income recapture exposure.
- California does not conform to the current federal 100 percent bonus depreciation rules.
- A defensible study should classify assets, explain the legal and technical basis for those classifications, substantiate costs, and reconcile the allocated costs to the property's total depreciable cost.
What Is a Cost Segregation Study?
Real estate is rarely one tax asset.
A purchased or constructed property can include land, a building, land improvements, equipment, appliances, furniture, specialized systems, and other assets that have different federal depreciation classifications.
Without a detailed allocation, taxpayers often place most depreciable acquisition or construction cost into the building account.
Under the general MACRS rules, residential rental property is generally depreciated over 27.5 years and nonresidential real property is generally depreciated over 39 years.
A cost segregation study examines the property and supporting records to determine whether portions of that cost are properly assigned to assets with shorter recovery periods.
| General Property Category | Common Federal Recovery Period |
|---|---|
| Certain tangible personal property | 5 or 7 years |
| Certain land improvements | 15 years |
| Residential rental building | 27.5 years |
| Nonresidential real property | 39 years |
| Land | Not depreciable |
Cost Segregation Does Not Arbitrarily Convert a Building Into Personal Property
The strategy works only to the extent that individual assets are properly classified under the tax law.
The taxpayer still needs support for the asset classification, recovery period, allocated cost, and relationship of the asset to the building or business activity.
Why Is Cost Segregation Especially Important Under the Current Bonus Depreciation Rules?
Current federal law provides a permanent 100 percent additional first year depreciation deduction for certain qualified property acquired and placed in service after January 19, 2025.
Qualified property generally includes eligible tangible property depreciated under MACRS with a recovery period of 20 years or less.
This means a cost segregation study can potentially identify assets within a real estate acquisition that qualify for a full federal depreciation deduction in the year placed in service.
Potential examples include properly classified:
- 5 year property
- 7 year property
- 15 year land improvements
The remaining residential or nonresidential building continues to be depreciated over its applicable real property recovery period.
The Building Does Not Become 100 Percent Deductible
A cost segregation study does not make a 27.5 year residential rental building or 39 year commercial building eligible for 100 percent bonus depreciation.
The benefit comes from correctly identifying qualifying shorter recovery period assets contained within the overall project.
Can Used Rental Property Qualify for 100 Percent Bonus Depreciation?
Certain used property can qualify.
Federal bonus depreciation is not limited to newly manufactured or newly constructed assets. The acquisition requirements for used property must still be satisfied.
Among other requirements, the taxpayer generally cannot have previously used the property, and certain related party and carryover basis acquisitions do not qualify.
This makes cost segregation potentially relevant when an investor purchases an existing apartment building, rental property, office building, warehouse, or other qualifying real estate rather than constructing a new building.
Example: Cost Segregation on an Apartment Property
Accelerating Depreciation on a $2 Million Acquisition
Assume an investor purchases an apartment property and places it in service after January 19, 2025.
| Cost Allocation | Amount |
|---|---|
| Total property cost | $2,000,000 |
| Land allocation | $400,000 |
| Total depreciable basis | $1,600,000 |
| Cost segregation allocation to qualifying 5 year property | $240,000 |
| Cost segregation allocation to qualifying 15 year property | $160,000 |
| Remaining residential rental building | $1,200,000 |
Before cost segregation, most of the $1,600,000 depreciable basis might otherwise be recovered over the 27.5 year residential rental property recovery period.
The study has instead identified $400,000 of qualifying shorter recovery period property.
If all of that $400,000 satisfies the federal bonus depreciation requirements and the taxpayer does not elect out of bonus depreciation for the applicable property classes, the taxpayer could potentially deduct the qualifying $400,000 under the current 100 percent federal bonus depreciation rules.
The $1,200,000 remaining building basis would continue to be depreciated under the applicable residential rental property rules.
Estimate the Potential Depreciation Acceleration
My Cost Segregation Calculator can provide a preliminary estimate of the amount of property that might be shifted into shorter recovery periods and the potential federal depreciation acceleration.
The calculator is an estimation tool. It is not a cost segregation study, appraisal, tax return, or tax opinion.
Cost Segregation Accelerates Depreciation Rather Than Creating New Property Basis
Cost segregation is primarily a timing strategy.
The study generally reallocates depreciable basis among the appropriate tax asset categories. It does not create additional purchase price or construction cost.
The economic value generally comes from receiving deductions earlier.
Earlier deductions can create value because a taxpayer can retain cash that otherwise would have been paid in tax and potentially reinvest that capital.
The value of acceleration therefore depends on factors such as:
- The taxpayer's current marginal tax rate
- Whether the deduction can actually be used in the current year
- The amount of qualifying shorter recovery period property
- The anticipated holding period
- The taxpayer's expected future tax rates
- Potential depreciation recapture
- State income tax treatment
- The cost of obtaining the study
A Large Depreciation Deduction Is Not the Same as a Large Current Tax Benefit
The return must still determine whether the taxpayer is allowed to use the deduction.
A $300,000 depreciation deduction can produce a $300,000 suspended passive loss rather than a $300,000 reduction of current taxable income.
How Do Passive Activity Loss Rules Affect Cost Segregation?
This is one of the most important issues to analyze before ordering a cost segregation study.
Rental activities are generally passive under Section 469 unless an applicable exception applies.
A cost segregation study can dramatically increase depreciation and therefore increase the rental loss. If the loss is passive and the taxpayer does not have sufficient passive income or another rule allowing the deduction, the additional loss can be suspended.
Suspended losses are not necessarily lost. They generally carry forward under the passive activity rules until they can be used.
But the economic value of a cost segregation study can be materially lower if the accelerated deduction cannot be used for several years.
For a detailed discussion, see Suspended Passive Rental Losses: Four Ways Real Estate Investors Can Use Them .
Does Real Estate Professional Status Make Cost Segregation More Valuable?
It can.
Rental real estate losses can be nonpassive when the taxpayer qualifies as a real estate professional and materially participates in the applicable rental activity.
When those requirements are satisfied, accelerated depreciation may be able to offset nonpassive income, subject to the other applicable tax limitations.
Qualifying as a real estate professional does not automatically make every rental loss deductible. Material participation remains a separate requirement.
Basis limitations, the at risk rules, and the excess business loss rules can also continue to apply.
For more information, see Real Estate Professional Status: How Rental Property Owners Qualify and Deduct Losses .
Can Cost Segregation Be Especially Valuable for a Short Term Rental?
Potentially.
The Section 469 regulations provide exceptions under which certain activities involving short customer use periods are not treated as rental activities for passive activity purposes.
One important exception applies when the average period of customer use is 7 days or less.
Another can apply when the average period of customer use is 30 days or less and significant personal services are provided.
When an activity is not treated as a rental activity under these rules, the taxpayer generally applies the material participation tests to determine whether the activity is passive or nonpassive.
A taxpayer who materially participates in a qualifying short term lodging activity may therefore be able to use accelerated depreciation without satisfying the real estate professional tests that apply to rental real estate.
Short Term Rental Does Not Automatically Mean Nonpassive
A short customer use period can cause the activity to fall outside the regulatory definition of a rental activity.
The taxpayer must still satisfy an applicable material participation test for the trade or business activity to be nonpassive.
Can Other Loss Limitations Still Apply?
Yes.
Cost segregation does not override other provisions that restrict losses.
Depending on the ownership structure and facts, the taxpayer may need to consider:
- Partnership outside basis limitations
- S corporation shareholder basis limitations
- Section 465 at risk rules
- Section 469 passive activity limitations
- Section 461 excess business loss limitations for noncorporate taxpayers
Section 461(l) currently imposes a permanent limitation on excess business losses of noncorporate taxpayers. Amounts disallowed under that provision are generally treated as net operating loss carryovers under the current rules.
Can I Do a Cost Segregation Study on a Property I Already Own?
Often, yes.
A taxpayer does not necessarily lose the opportunity to perform cost segregation simply because the property was placed in service in an earlier tax year.
The implementation procedure depends on how depreciation was reported previously and whether the taxpayer has already adopted an accounting method for the property.
When the correction constitutes a change from an impermissible depreciation method to a permissible method, Form 3115 can generally be required or available under the applicable accounting method change procedures.
The change can include a Section 481(a) adjustment that compares the depreciation actually deducted before the year of change with the depreciation that should have been allowed under the corrected method.
A negative Section 481(a) adjustment generally decreases taxable income and is generally taken into account in the year of change.
Example: Cost Segregation Several Years After Purchase
Assume an investor acquired an apartment building several years ago and placed the entire depreciable cost into a 27.5 year residential rental building account.
A later cost segregation study determines that some of the original cost should have been classified as shorter recovery period property.
Depending on the taxpayer's depreciation history and the applicable accounting method rules, the taxpayer can potentially implement the corrected classification through Form 3115 and compute a Section 481(a) adjustment for depreciation that should previously have been deducted.
This can allow the taxpayer to correct prior depreciation prospectively without necessarily amending every prior year return.
Form 3115 Is Not the Correct Procedure in Every Situation
The proper procedure depends on whether an accounting method has already been adopted, the property's depreciation history, prior returns, elections, and the particular change being made.
In some situations an amended return can be required or permitted instead.
Does a Cost Segregation Study on an Older Property Get the Current 100 Percent Bonus Rate?
Not automatically.
The current 100 percent bonus depreciation rule does not simply turn property placed in service years ago into newly acquired 2026 property.
When a taxpayer corrects prior depreciation through a Section 481(a) adjustment, the calculation generally determines the depreciation that should have been allowed under the tax law applicable to the property's original placed in service period.
The Original Placed in Service Year Matters
A cost segregation study performed today on a property acquired in an earlier year does not automatically cause the shorter recovery period assets to qualify for the current 100 percent bonus depreciation rules.
Historical bonus depreciation percentages, elections, acquisition rules, and other depreciation provisions must be considered when computing the correction.
What Types of Assets Can a Cost Segregation Study Identify?
Classification is highly dependent on the property, business use, installation, function, and applicable tax authorities.
Potential shorter recovery period assets can include, when the applicable requirements are satisfied:
- Appliances
- Certain removable floor coverings
- Furniture and removable equipment
- Certain dedicated electrical systems serving qualifying equipment
- Certain specialized plumbing serving qualifying equipment
- Certain exterior lighting
- Certain fencing
- Certain paving and site improvements
- Certain landscaping associated with depreciable improvements
- Other qualifying land improvements
Assets that are structural components of the building generally remain part of the residential rental or nonresidential real property classification.
Examples can include:
- Structural walls
- Roof systems
- Building foundations
- General building plumbing
- General building electrical systems
- Building heating and cooling systems
- Structural floors and permanently installed floor systems
Generic Asset Lists Are Not a Substitute for Classification Analysis
The same type of component can receive different treatment depending on its function, installation, industry, and relationship to the building.
A study should explain why an asset receives a particular classification rather than simply applying a standard percentage to every property.
Land Must Be Separated From the Depreciable Property
Land is not depreciable.
Before determining how much acquisition basis can be depreciated, the taxpayer must make a reasonable and supportable allocation of the property cost between land and depreciable property.
A cost segregation study generally analyzes the depreciable property after that land allocation has been established.
An aggressive allocation that understates land can overstate depreciation regardless of how well the remaining cost segregation work is performed.
What Makes a Defensible Cost Segregation Study?
The IRS Cost Segregation Audit Technique Guide is not an official pronouncement of tax law, but it provides useful insight into the factors IRS examiners are instructed to consider when reviewing studies.
The guide states that a cost segregation study should classify assets into appropriate property classes, explain the rationale for Section 1245 or Section 1250 treatment, substantiate the cost basis of each asset, and reconcile allocated costs to total actual costs.
The IRS guide identifies several characteristics of a quality study, including:
- Preparation by a person with relevant expertise and experience
- A detailed explanation of methodology
- Appropriate supporting documentation
- Explanation of the legal analysis
- Support for unit costs and engineering estimates
- Organized asset schedules
- Reconciliation of allocated costs to actual costs
- Explanation of indirect cost treatment
- Identification of Section 1245 property
- Consideration of accounting method and other related tax issues
Be Cautious With Unsupported Percentage Studies
A report that simply assumes that a fixed percentage of every building is 5 year property does not provide the same level of support as a study tied to the actual property, plans, construction information, replacement costs, invoices, or other reliable evidence.
Purchased Buildings and New Construction Require Different Approaches
Newly constructed property can provide detailed source information such as:
- Architectural plans
- Engineering drawings
- Construction contracts
- Contractor invoices
- Change orders
- Equipment schedules
- Direct and indirect construction costs
An investor purchasing an existing building usually does not have the seller's original construction cost records.
A purchased property study can therefore require estimates of component costs based on property inspections, plans, replacement cost information, industry cost data, and other available records.
The absence of original construction invoices does not necessarily prevent a cost segregation analysis, but the methodology and assumptions should be clearly documented.
Do I Have to Claim 100 Percent Bonus Depreciation?
Bonus depreciation generally applies to eligible qualified property unless the taxpayer makes a valid election out for the applicable class of property.
Maximum acceleration is not necessarily the best answer in every situation.
A taxpayer might consider electing out for an eligible class when:
- The additional deduction would simply create suspended passive losses
- Current taxable income is relatively low
- The taxpayer expects a materially higher future tax rate
- Future deductions are expected to provide greater economic value
- Other deductions already eliminate most current taxable income
- State tax treatment materially differs from federal treatment
The depreciation election should therefore be coordinated with the taxpayer's overall return rather than made solely because the deduction is available.
What Happens When Cost Segregated Property Is Sold?
Accelerating depreciation can affect the eventual disposition of the property.
Some assets identified through cost segregation can be Section 1245 property.
When Section 1245 property is later disposed of at a gain, prior depreciation allowed or allowable can generally be recaptured as ordinary income to the extent required by Section 1245.
The building and other Section 1250 property are subject to different rules.
Land is not depreciable and does not create depreciation recapture.
Example: Accelerated Deduction Today and Recapture Later
Assume a cost segregation study assigns $100,000 to qualifying Section 1245 property and the taxpayer receives a full $100,000 depreciation deduction.
If the taxpayer later sells that particular property at a sufficient gain, Section 1245 can cause gain to be treated as ordinary income up to the amount required by the depreciation recapture rules.
The possibility of future recapture does not automatically eliminate the value of the earlier deduction.
The analysis should compare the timing value of the accelerated tax deduction with the expected future tax cost.
For a detailed explanation of these rules, see Depreciation Recapture on Rental Property: Sections 1245, 1250, and the 25 Percent Rate .
How Does Cost Segregation Affect Section 1231 Gain or Loss?
The property classifications created by a cost segregation study can affect how a future sale is reported.
Depreciation recapture is generally determined first for the applicable assets. Remaining qualifying gains and losses can then enter the Section 1231 calculation.
This means the investor should not assume that a building purchased as one property will produce only one type of gain when it is later sold.
For more information, see Section 1231 Tax Rules for Rental Property and Business Real Estate .
How Does Cost Segregation Affect a Section 1031 Exchange?
Cost segregation and Section 1031 use different classification rules for different tax purposes.
Current Section 1031 treatment is limited to qualifying real property.
A cost segregation study can identify assets that are Section 1245 property for depreciation purposes, while the Section 1031 regulations separately determine whether a particular asset is real property for exchange purposes.
Therefore, the depreciation classification should not be used as the sole test for determining whether each component qualifies in a Section 1031 exchange.
When a property with a cost segregation study is exchanged, the transaction should coordinate:
- The tax classification of the relinquished property components
- The classification of replacement property
- Depreciation recapture rules
- Recognized gain or boot
- Carryover and excess basis
- Future depreciation schedules
Can Cost Segregation Help With Later Building Component Dispositions?
Detailed asset level records can provide another practical benefit.
If a taxpayer later replaces a major building component, the tangible property regulations can permit a partial disposition analysis in appropriate circumstances.
A detailed cost segregation report can help identify and support the historical basis of specific components that are later removed or replaced.
A cost segregation study does not automatically create a partial disposition deduction. The separate disposition requirements, elections, timing rules, and facts must still be satisfied.
California Does Not Allow the Current Federal 100 Percent Bonus Depreciation
California investors need a separate state analysis.
California does not conform to the federal additional first year depreciation rules under Section 168(k), including the current federal provision providing 100 percent bonus depreciation for certain qualified property acquired and placed in service after January 19, 2025.
As a result, a cost segregation study can create a significant difference between federal and California depreciation.
Federal and California Depreciation Can Diverge Immediately
Assume a cost segregation study identifies $300,000 of property that qualifies for 100 percent federal bonus depreciation.
The taxpayer may receive a $300,000 federal first year bonus depreciation deduction if all federal requirements are satisfied.
California does not simply follow that federal bonus deduction.
California depreciation for the affected assets must instead be determined under the applicable California conformity rules.
The result can be different federal and California depreciation deductions, different adjusted bases, and eventually different gain calculations when the property is sold.
Maintain Separate Federal and California Depreciation Schedules
The federal and California difference does not disappear after the year of acquisition.
Separate depreciation records can be needed throughout the property's holding period and through the eventual sale or exchange.
What Records Should Be Kept After a Cost Segregation Study?
Cost segregation creates a long term recordkeeping requirement.
Important records can include:
- Purchase closing statement
- Purchase agreement
- Land and building allocation support
- Original fixed asset and depreciation schedules
- The complete cost segregation study
- Supporting engineering and cost schedules
- Construction invoices and plans when available
- Federal depreciation schedules after the study
- California depreciation schedules
- Form 3115 when applicable
- Section 481(a) adjustment computation when applicable
- Records of later improvements
- Records of replaced or disposed building components
- Section 1031 exchange records when applicable
These records can become important years later when the investor sells the property and must determine adjusted basis and depreciation recapture.
When Can Cost Segregation Be Especially Valuable?
Cost segregation can be particularly worth evaluating when:
- A recently acquired property has substantial depreciable basis
- The property includes meaningful personal property or land improvements
- The investor has current taxable income against which the deductions can be used
- The investor has sufficient passive income
- The investor qualifies as a real estate professional and materially participates
- A qualifying short term rental activity is nonpassive because the taxpayer materially participates
- The property was substantially renovated or newly constructed
- The investor expects to hold the property for a meaningful period
- An older property may produce a significant Section 481(a) catch up adjustment
- The time value of the accelerated tax savings materially exceeds the cost of the study
When Might Cost Segregation Not Be Worth It?
Cost segregation is not automatically beneficial for every real estate investor.
The strategy deserves closer scrutiny when:
- The accelerated deduction will simply create large suspended passive losses
- The property has relatively little depreciable basis
- The expected shorter recovery period allocation is small
- The property may be sold in the near future
- Potential recapture significantly reduces the economic benefit
- The taxpayer is currently in a relatively low income tax bracket
- The study cost is large relative to the expected tax savings
- California nonconformity materially reduces the combined federal and state benefit
- The taxpayer already has deductions sufficient to reduce taxable income
- The investor prefers deductions in future years rather than maximum acceleration today
The Correct Question Is Not How Large the Deduction Is
The more useful question is how much current and future tax value the accelerated deduction creates after considering passive activity limitations, federal and state differences, recapture, study cost, and the investor's expected holding period.
What Should Be Reviewed Before Ordering a Cost Segregation Study?
A preliminary tax review should generally consider:
- Property purchase price
- Land allocation
- Depreciable building basis
- Property type
- Acquisition date
- Placed in service date
- Expected shorter recovery period allocation
- Prior depreciation claimed
- Whether Form 3115 may be required
- Federal bonus depreciation eligibility
- Whether electing out of bonus depreciation should be considered
- Passive or nonpassive activity status
- Real estate professional status when relevant
- Material participation
- Short term rental customer use periods when relevant
- Existing suspended passive losses
- Basis and at risk limitations
- Potential Section 461 excess business loss limitation
- Federal marginal tax rate
- California depreciation differences
- Expected property holding period
- Expected disposition or Section 1031 exchange
- Potential depreciation recapture
- Estimated study cost
Frequently Asked Questions About Cost Segregation
What is a cost segregation study?
A cost segregation study analyzes a real estate acquisition or construction project and identifies assets that should be assigned to different federal depreciation classifications. The objective is to separate qualifying shorter recovery period property from the longer recovery period building and from nondepreciable land.
How does cost segregation work for rental property?
Instead of placing all depreciable cost into a 27.5 year residential rental building or 39 year nonresidential building, a properly supported study can identify assets that qualify for shorter recovery periods such as 5, 7, or 15 years. Eligible shorter recovery period property can also qualify for bonus depreciation when the federal requirements are satisfied.
What property qualifies for cost segregation?
Cost segregation can be relevant to residential rental property, apartment buildings, commercial buildings, warehouses, offices, retail property, hospitality property, and many other real estate investments. The amount that can be separately classified depends on the property's actual components and use.
Is cost segregation worth it?
It depends on the amount of depreciation that can be accelerated, whether the taxpayer can currently use the resulting deduction, the taxpayer's tax rates, study cost, holding period, future recapture, and state tax treatment.
Does cost segregation create additional depreciation?
Cost segregation generally reallocates existing depreciable basis into the proper asset classifications. Its principal benefit is accelerating when depreciation is deducted rather than creating additional acquisition basis.
Can I use 100 percent bonus depreciation with cost segregation?
Under current federal law, certain qualified property acquired and placed in service after January 19, 2025 can qualify for 100 percent bonus depreciation. Eligible tangible MACRS property with a recovery period of 20 years or less can generally qualify when the other statutory requirements are satisfied.
Does used rental property qualify for bonus depreciation?
Certain used property can qualify when the federal acquisition requirements are satisfied. Related party acquisitions, prior use by the taxpayer, carryover basis transactions, and other statutory restrictions can prevent qualification.
Can I do a cost segregation study on a property I bought several years ago?
Often, yes. Depending on how depreciation was previously reported, the taxpayer can potentially correct the depreciation method through Form 3115 and a Section 481(a) adjustment. The proper filing procedure depends on the taxpayer's prior method and depreciation history.
Do I have to amend prior returns after a cost segregation study?
Not necessarily. When the correction qualifies as an accounting method change, Form 3115 and a Section 481(a) adjustment can generally be used rather than amending every prior year. Different procedures can apply when an accounting method has not yet been adopted or another specific rule applies.
What is a Section 481(a) catch up adjustment?
A Section 481(a) adjustment generally measures the cumulative difference between depreciation actually deducted before the year of change and depreciation that should have been deducted under the corrected method. A negative adjustment generally reduces taxable income in the year of change.
Does a cost segregation study today give an older property the current 100 percent bonus depreciation rate?
Not automatically. The correction generally must reflect the depreciation rules that applied based on the property's original acquisition and placed in service facts. A later study does not simply convert an older asset into newly acquired property.
Does cost segregation work for residential rental property?
Yes. The IRS Cost Segregation Audit Technique Guide includes specific guidance addressing residential rental property and the classification of common assets. The actual classifications depend on the property and facts.
Does cost segregation work for commercial real estate?
Yes. Commercial real estate can contain qualifying personal property, land improvements, and other components with shorter recovery periods than the 39 year building.
Does cost segregation work for short term rentals?
Yes. Short term rental property can qualify for cost segregation. The potential current tax benefit can be particularly significant when the activity falls outside the Section 469 rental activity definition and the taxpayer materially participates, but the actual passive activity classification must be determined from the facts.
Can cost segregation create suspended passive losses?
Yes. Accelerated depreciation can increase a passive rental loss. If the taxpayer cannot use the loss under Section 469, the loss can be suspended and carried forward rather than producing an immediate current tax benefit.
Does real estate professional status affect cost segregation?
It can. A taxpayer who qualifies as a real estate professional and materially participates in the applicable rental real estate activity can potentially treat the activity as nonpassive, making accelerated depreciation more immediately useful. Other loss limitations can still apply.
What happens to cost segregation deductions when I sell the property?
The sale must account for the separate tax assets and the depreciation allowed or allowable. Section 1245 property can generate ordinary income depreciation recapture, while Section 1250 property follows different rules. The resulting tax should be modeled before the sale.
Does cost segregation cause depreciation recapture?
Cost segregation can increase the amount of property classified under Section 1245, which can increase ordinary income recapture when those assets are later disposed of at a gain. The earlier tax benefit should therefore be evaluated together with the future disposition.
How does cost segregation affect a Section 1031 exchange?
A cost segregation study creates separate depreciation classifications that must be coordinated with the Section 1031 rules when property is exchanged. The depreciation classification does not by itself determine whether an asset is real property for Section 1031 purposes.
Does California allow 100 percent bonus depreciation from a cost segregation study?
No. California does not conform to the current federal bonus depreciation provision under Section 168(k). A California investor can therefore have significantly different federal and California depreciation deductions and adjusted basis.
What records should I keep after a cost segregation study?
Keep the complete study, acquisition records, land allocation support, federal and state depreciation schedules, Form 3115 and Section 481(a) calculations when applicable, and records of subsequent improvements and property dispositions.
When is cost segregation not worth doing?
Cost segregation may provide limited current value when the taxpayer cannot use the accelerated deductions, the depreciable basis is small, the study cost is high, the property will be sold soon, or state tax and recapture consequences substantially reduce the expected benefit.
Final Takeaway
Cost segregation can be one of the more powerful depreciation planning strategies available to a real estate investor, particularly under the current federal 100 percent bonus depreciation rules.
The size of the first year deduction should not be the only factor driving the decision.
A meaningful cost segregation analysis should consider whether the taxpayer can actually use the accelerated deductions, whether losses will be passive, whether a prior year study requires Form 3115, the expected holding period, depreciation recapture, California differences, and the quality of the study supporting the classifications.
For an existing property, the analysis should also determine whether a catch up adjustment can be claimed and which historical depreciation rules apply.
For a new acquisition, the analysis should occur early enough to coordinate the property purchase allocation, depreciation elections, passive activity treatment, and federal and state reporting before the tax return is filed.
Determine Whether a Cost Segregation Study Makes Sense Before Ordering One
I assist real estate investors with cost segregation tax benefit reviews before and after a study is performed.
The analysis can include depreciable basis, federal bonus depreciation, passive activity limitations, real estate professional status, short term rental treatment, partnership and S corporation loss limitations, California depreciation differences, prior depreciation, Form 3115 opportunities, expected holding period, and future recapture.
The objective is to determine whether accelerating depreciation is likely to create an actual tax benefit on your return rather than simply generating a large depreciation deduction on paper.
Schedule a ConsultationThis article provides general federal and California income tax information.
