A large first-year deduction is only the first entry in a much longer tax record.
Quick answer: Cost segregation can accelerate depreciation on eligible parts of a U.S. short-term rental, but it does not make the later exit tax-free. A sale may produce Section 1245 ordinary-income recapture, unrecaptured Section 1250 gain or both. A Section 1031 exchange and a later primary-home exclusion have separate limits. Property inherited at death may receive a new basis, but the result depends on ownership and estate facts. Model the acquisition and exit together before treating a first-year deduction as an investment return.
Editorial note: This article uses an anonymized scenario drawn from user-provided material. The owner's income, property results, participation records, tax returns and cost-segregation studies were not independently verified. This article provides general educational information, not individualized tax, legal, accounting, estate-planning or investment advice.
The Exit Question a First-Year Projection Can Hide
Consider a furnished vacation rental whose owner orders a cost-segregation study after purchase. Instead of depreciating all eligible building basis over the same 27.5-year schedule, the study identifies assets that may belong in shorter recovery periods. If those assets qualify for bonus depreciation, the owner may claim a much larger deduction near the beginning of the investment.
The projection looks compelling. The owner then describes one of four possible plans:
- sell the property when the market is favorable;
- exchange it for another investment property;
- move into it and later claim the home-sale exclusion; or
- hold it for life and leave it to heirs.
Those are not interchangeable ways to make depreciation disappear. They are four different tax paths. Each depends on the property's adjusted basis, the character of individual assets, the owner's use of the property, transaction timing and how the property is held.
If the first question is whether an STR loss can offset W-2 income, start with our separate guide to the seven-day classification rule, material participation and loss limitations. This article begins one step later: after depreciation has been claimed.
Cost Segregation Creates an Asset Map, Not Free Basis
A purchased rental is not one tax asset. At a minimum, the acquisition can involve:
- land, which is not depreciable;
- a residential rental building, generally depreciated over 27.5 years under the general depreciation system;
- land improvements that may have a shorter recovery period;
- furniture, appliances and equipment; and
- other components whose classification depends on their facts and function.
A defensible cost-segregation study allocates supported depreciable basis among those categories. It does not create additional basis, turn land into depreciable property or prove that a loss is currently deductible.
Current federal law generally restored 100% additional first-year depreciation for eligible qualified property acquired after January 19, 2025, subject to acquisition, binding-contract, prior-use, related-party, placed-in-service and other rules. That does not mean an entire STR receives a 100% write-off. Ordinary residential-building basis is generally outside the “20 years or less” qualified-property route, while eligible furniture and properly classified shorter-life components may qualify. See IRS Notice 2026-11 and Publication 946.
The adjusted-basis effect
Depreciation generally reduces the adjusted basis of the asset. The simplified relationship is:
Original allocated basis
+ later capital additions
− depreciation allowed or allowable
= adjusted basis before the sale
“Allowed or allowable” matters. An owner generally cannot preserve basis merely by failing to claim depreciation that should have been claimed. The historical fixed-asset ledger and depreciation schedules therefore remain important long after the first return is filed.
Exit 1: Sell the Property
A later sale is analyzed across the assets that were sold. The building, land, furniture, equipment and certain improvements may not all produce the same character of income.
| Asset category | Common federal issue at sale | Why the record matters |
|---|---|---|
| Furniture, equipment and many shorter-life cost-seg assets | Section 1245 recapture may treat gain as ordinary income up to the applicable depreciation amount | The owner needs original basis, depreciation and sale-price allocation for each asset |
| Residential building | Straight-line building depreciation can contribute to unrecaptured Section 1250 gain, generally subject to a maximum 25% federal rate | This is not the same as saying every dollar is automatically taxed at 25% |
| Land | Land is not depreciated, but its allocated sale proceeds and basis affect real-estate gain | A weak land/building allocation can distort both acquisition and exit calculations |
Section 1245 is not the same as unrecaptured Section 1250 gain
For Section 1245 property, gain is generally treated as ordinary income to the extent of prior depreciation, subject to the statutory calculation. A large bonus-depreciation deduction can therefore increase the amount of historical depreciation relevant to a later sale.
Residential rental buildings are commonly depreciated using straight-line MACRS. That often means the building does not generate traditional Section 1250 ordinary-income recapture based on “additional depreciation.” But the depreciation-related portion of long-term real-property gain may still be unrecaptured Section 1250 gain, which has a maximum federal rate of 25%.
The two most common shortcuts are both misleading:
- “You pay every dollar of depreciation back when you sell.”
- “There is no recapture on residential rental property.”
The actual result depends on gain, asset character, depreciation history, selling-price allocation, suspended losses, holding period and the rest of the return. IRS Publication 544, the Form 4797 instructions and the Schedule D instructions provide the federal starting points.
A simple illustration
Suppose a property sale includes furniture with:
Original furniture basis: $40,000
Accumulated depreciation: $40,000
Adjusted furniture basis: $0
Allocated furniture sale price: $15,000
Ignoring transaction costs and other complications, the $15,000 gain may fall within the Section 1245 recapture calculation and be treated as ordinary income. That example does not determine what happens to the building or land. It shows why “the property sold for one price” is not a sufficient fixed-asset analysis.
Exit 2: Exchange the Property Under Section 1031
A properly structured Section 1031 exchange can defer recognition of gain on qualifying business or investment real property. It is a deferral system, not a basis reset.
Since 2018, Section 1031 has generally applied only to real property. Furniture and other personal property transferred with a furnished STR may not qualify merely because they were sold in the same contract. Regulations also make clear that the real-property definition used for Section 1031 does not decide whether property is treated as Section 1245 or Section 1250 property for the recapture rules.
That creates several questions before the sale closes:
- Which transferred assets are qualifying real property?
- Which are furniture, equipment or other personal property?
- How will consideration be allocated among the assets?
- Will cash, debt relief or other non-like-kind property cause current gain recognition?
- How will carryover basis and any additional basis be tracked in the replacement property?
- Which depreciation methods and recovery periods apply after the exchange?
The fact that incidental personal property does not invalidate identification of replacement real property under a regulatory safe harbor does not automatically make that personal property eligible for nonrecognition. Review the IRS overview of like-kind exchanges and the federal definitions in Treasury Regulation §1.1031(a)-3.
An owner who plans to exchange should involve qualified tax and exchange professionals before signing or closing. The statutory timelines, taxpayer identity, qualified-intermediary structure and disposition of personal property are difficult to repair after receiving the sale proceeds.
Exit 3: Move Into the Rental and Sell It as a Home
Converting an STR into a principal residence does not erase the property's depreciation history.
Section 121 may exclude some gain on a qualifying principal-home sale when the ownership and use tests are satisfied—generally, ownership and use as a principal residence for at least two years during the five-year period ending on the sale date. But a former rental introduces additional limits:
- gain attributable to depreciation allowed or allowable after May 6, 1997, is not excludable under Section 121;
- post-2008 periods of nonqualified use may require allocation of gain;
- personal use must be real principal-residence use, not simply a change in the mailing address; and
- if the property was acquired in a Section 1031 exchange, Section 121 generally cannot apply to a sale during the five-year period beginning with that acquisition.
The conversion itself is not a sale that magically settles the old depreciation. The relevant calculations commonly appear when the property is eventually sold.
Use IRS Publication 523 to frame the home-sale questions, then give the complete rental, exchange, depreciation and occupancy history to the adviser preparing the calculation.
Exit 4: Hold the Property Until Death
Property acquired from a decedent generally receives a basis tied to fair market value at death, or to an alternate valuation date when a valid election applies. That can materially change the built-in income-tax gain. It can also produce a step-down when value has fallen.
Transfers at death also receive specific treatment under the Section 1245 and Section 1250 recapture provisions. But “my heirs get a step-up” is still not a complete estate plan.
The result can depend on:
- whether the property is actually acquired from the decedent under Section 1014;
- direct, partnership, LLC or trust ownership;
- whether the asset is included in the decedent's gross estate;
- community-property and state-law facts;
- partnership inside and outside basis and any available election;
- debt and estate liquidity; and
- income-in-respect-of-a-decedent and other statutory exceptions.
For example, Revenue Ruling 2023-2 explains that property held in an irrevocable grantor trust does not receive Section 1014 treatment merely because it is a grantor trust when the asset is not included in the grantor's gross estate. Start with IRS Publication 559, then have estate and tax advisers analyze the actual ownership documents.
Holding until death may be an intentional plan. It should not be a slogan used to ignore operating risk, concentration, financing, family objectives or future law changes.
Compare the Four Paths Before Ordering the Study
The best time to ask about exit tax is before the first depreciation schedule is created.
| Potential path | Model before purchase or cost segregation | Evidence to preserve |
|---|---|---|
| Direct sale | Three-, five- and ten-year sale prices; selling costs; asset allocation; federal and state character of gain | Fixed-asset ledger, depreciation schedules, invoices, cost-seg report and sale documents |
| Section 1031 exchange | Real versus personal property; debt replacement; boot; exchange expenses; replacement-property basis | Exchange agreement, qualified-intermediary records, closing statements and asset schedules |
| Convert to principal residence | Rental period, planned move-in, two-of-five tests, nonqualified use and prior 1031 acquisition date | Rental calendar, actual occupancy evidence, returns and complete depreciation history |
| Hold until death | Ownership structure, estate inclusion, valuation, debt, succession and liquidity | Deed, entity and trust documents, estate plan, basis records and appraisals |
Cost segregation can still be economically useful when an owner expects a future sale. The question is not whether recapture exists in the abstract. The question is whether the present value of accelerated deductions, the operating economics and the modeled exit consequences make sense together.

Questions to Ask the CPA Before You Decide
- “Please show the projected adjusted basis by asset after one, three, five and ten years.”
- “Which assets do you expect to be Section 1245 property, Section 1250 property or land?”
- “How would a direct sale allocate consideration, and which amounts could be ordinary income, unrecaptured Section 1250 gain or other capital gain?”
- “If we pursue a 1031 exchange, which furnishings or other assets may fall outside nonrecognition?”
- “How will carryover basis and additional basis be depreciated in the replacement property?”
- “If we later move in, how would depreciation and nonqualified use limit Section 121?”
- “Does our LLC, partnership or trust structure receive the basis result we expect at death?”
- “Which state returns or decoupled depreciation rules change the model?”
- “What facts would make your conclusion change?”
A useful analysis identifies assumptions and contrary outcomes. A guaranteed deduction or a promise that recapture “will never matter” is not a substitute for that work.
Frequently Asked Questions
Is short-term-rental depreciation recapture always taxed at 25%?
No. The 25% figure is commonly associated with the maximum federal rate on unrecaptured Section 1250 gain. Many furniture, equipment and shorter-life assets can instead fall under Section 1245 ordinary-income recapture. The result also depends on actual gain, depreciation, asset allocation and the owner's broader return.
Does bonus depreciation get recaptured when an STR is sold?
Bonus depreciation becomes part of the asset's depreciation history and reduces adjusted basis. If Section 1245 property is later sold at a gain, the prior bonus depreciation can increase the amount relevant to ordinary-income recapture, subject to the statutory calculation.
Does a 1031 exchange eliminate depreciation recapture?
Not automatically. A qualifying exchange can defer recognition on eligible real property, but it does not erase basis or depreciation history. Furnishings and other personal property may not qualify, and cash or other non-like-kind property can cause current recognition.
Can I avoid recapture by turning the rental into my primary home?
Moving in does not erase prior depreciation. Even when the ownership and residence-use requirements for Section 121 are met, gain attributable to post-May 6, 1997 depreciation is not excludable. Nonqualified use and a prior Section 1031 acquisition can impose additional limits.
Do heirs always receive a stepped-up basis on an STR?
Property acquired from a decedent generally receives a basis tied to fair market value at death, subject to the governing rules and any valid alternate-valuation election. Trust, partnership, LLC, estate-inclusion and state-law facts can change how that general rule applies. A falling property can also receive a step-down.
What happens to suspended passive losses when the property is sold?
A fully taxable disposition of the entire interest to an unrelated party can release certain suspended passive losses under Section 469, but basis, at-risk and other limitations still matter. A 1031 exchange or conversion to personal use is not the same transaction. Review the complete history under Publication 925.
Should I skip cost segregation if I expect to sell?
Not necessarily. The decision depends on the timing and amount of the deduction, marginal rates, the quality and cost of the study, operating results, expected hold period, sale price, asset character and state treatment. Compare the present value of the benefit with the modeled exit instead of treating either the deduction or recapture in isolation.
