Inherited Rental Cost Segregation: Bonus?

Q: Does the depreciation schedule start over when I inherit?

Generally the heir uses a new schedule, not the decedent's remaining schedule. The heir's placed-in-service date is when the rental is ready and available for rental use, which may be later than the date of death.

Yes, a cost segregation study can work on an inherited rental, but the inherited Section 1014 basis generally does not qualify for bonus depreciation. The decision is whether asset-level regular MACRS acceleration on the heir's properly determined depreciable basis is worth the study cost and can be used under the loss rules. The inherited basis is generally date-of-death fair market value, subject to estate-value and other exceptions. Review the valuation and filing year before ordering a study.

An heir may receive a new basis even when the decedent had nearly fully depreciated the rental. Land remains nondepreciable, and an appraisal must support the land, building, and component amounts. A study may accelerate deductions, but it does not guarantee a large first-year deduction or an immediately usable loss.

Establish the Inherited Basis First

Under IRC Sec. 1014(a), the basis of property acquired from a decedent is its fair market value on the date of death, or on the alternate valuation date if elected.

Under the general Section 1014 rule, the heir does not carry over the decedent's accumulated depreciation schedule, and the death transfer itself does not trigger depreciation recapture. Exceptions and the amount actually included in the estate must still be checked. Later depreciation claimed by the heir reduces the heir's basis and affects a later sale.

For a simplified example with no Section 1014 exception, assume a property was purchased for $260,000 in 1994, had a $40,000 adjusted basis in the decedent's hands, and has a supported $920,000 date-of-death value. The heir's starting basis is $920,000, not the $40,000 remaining on the decedent's schedule. This does not make land depreciable or eliminate the need to verify estate-value consistency.

The heir then allocates the new basis between land and building and begins a new depreciation schedule.

The New Depreciation Schedule

The heir uses a new depreciation schedule based on the inherited property's own tax basis and placed-in-service date. An ongoing rental may be ready and available for rental use at inheritance; a vacant property held for personal use or under renovation may be placed in service later. The building portion of residential rental property generally uses 27.5 years and nonresidential real property generally uses 39 years; properly identified shorter-life assets have separate recovery periods. See IRS Publication 527 for the ready-and-available rule.

This is worth emphasizing. The heir does not inherit the decedent's remaining recovery period. A property with three years left on a 27.5-year schedule in the decedent's hands starts a fresh 27.5 years in the heir's hands.

On the simplified example above, $920,000 of inherited basis less $170,000 allocated to land leaves $750,000 of potentially depreciable basis. Dividing that amount by 27.5 yields a rough $27,273 annual straight-line comparison, not the first-year MACRS deduction; the placed-in-service month, convention, use, and any shorter-life assets change the actual schedule.

When a Study May Add Value

When a documented inherited basis exceeds the decedent's old adjusted basis, the dollar amount potentially allocated to shorter-life components may be larger. That does not establish the correct allocation percentage or the deduction's immediate tax value.

For illustration, a study that supports reclassifying 24% of a $750,000 depreciable basis identifies $180,000 of shorter-life assets. That amount is not automatically eligible for bonus depreciation: the IRS used-property test excludes property whose basis is determined under Section 1014(a). The possible benefit is regular MACRS acceleration, subject to the heir's usable-loss position and the cost of a defensible study.

Inherited components must be reconciled to the applicable estate valuation date, not simply priced from the original construction invoices. A quality study should document the valuation method, asset descriptions, classifications, and reconciliation to total depreciable basis; a flat percentage unsupported by property facts is not enough. The IRS Cost Segregation Audit Techniques Guide describes the evidence examiners evaluate.

Where a formal appraisal was obtained for estate purposes, it becomes a useful starting point and helps establish the total, but the component allocation still requires the study.

The Bonus Depreciation Question

Property acquired from a decedent generally has a basis determined under IRC Sec. 1014 rather than the decedent's old adjusted basis. That does not by itself satisfy the separate bonus-depreciation acquisition test.

Even if the heir never used the property before inheritance, the inherited Section 1014(a) basis fails a separate requirement for bonus depreciation on acquired used property. A cost segregation study can still identify properly valued shorter-life assets for regular MACRS depreciation. Separately purchased or constructed improvements after inheritance must be tested on their own facts and acquisition dates; they do not make the inherited basis bonus-eligible.

Where the heir already owned an interest, first separate the previously owned share from the share acquired from the decedent. Each portion can have a different basis history, and the amount included in the decedent's estate controls any Section 1014 adjustment. Do not apply a full-property step-up or a single depreciation schedule to both portions without reviewing title, estate reporting, and prior deductions.

Community property adds a separate basis question. Under IRC Sec. 1014(b)(6), both spouses' halves can receive a date-of-death basis adjustment when the statutory conditions are met, including inclusion of at least one-half of the community property's value in the decedent's gross estate. Confirm title, state community-property law, and estate reporting before assuming a full-property adjustment.

Separate the assets before estimating a deduction

Basis or asset group	Cost segregation question	Bonus-depreciation question
Inherited Section 1014 basis	Can the appraised building basis be allocated to supportable shorter-life assets?	Generally no bonus for that inherited basis; test regular MACRS instead.
Land	How much of the inherited value is nondepreciable land?	Neither regular nor bonus depreciation applies to land.
Previously owned co-owner share	What is its separate adjusted basis and existing depreciation schedule?	Do not treat it as newly acquired solely because the other owner died.
Later purchased or constructed improvements	Classify and date each new item separately from inherited property.	Apply the acquisition, original-use or used-property, and placed-in-service tests to that item.

Timing and the Estate Return

Review the estate records for the applicable valuation date and any Form 8971 Schedule A furnished to the beneficiary. Section 1014(f) can require consistency with the final federal estate-tax value for covered property; do not assume every asset on every estate return is subject to the same reporting condition. IRS Publication 551 describes the inherited-basis exceptions and consistency rule.

Where no estate return or beneficiary value statement is required, a qualified date-of-death appraisal is important support for the claimed basis and land allocation. Reconstructing that value years later may be possible but can be harder to substantiate.

The heir should preserve the estate documents and valuation work before commissioning a component study. Appraisal cost varies by property and scope; the relevant question is whether the records support the basis used for depreciation and later gain or loss.

Passive Loss Considerations

Depreciation from an inherited rental is subject to the same basis, at-risk, and passive-activity limits as other rental deductions. An heir with W-2 income does not automatically lose or suspend every rental loss: passive income, the active-participation special allowance (subject to income phaseout), real-estate-professional status plus material participation, or a nonrental short-stay activity can change the result. See IRS Publication 925. Model actual year-one usable deductions before buying a study.

There is a separate rule worth knowing. Under IRC Sec. 469(g)(2), suspended passive losses of the decedent are allowed on the final return only to the extent they exceed the increase in basis of the activity's property at death. Compute the actual basis increase and suspended loss for each activity; neither a full deduction nor complete elimination should be assumed.

That is a planning point for the decedent, not the heir. An owner with large suspended passive losses and advanced age should consider whether triggering those losses through a disposition during life produces a better result than losing them at death.

Worked Example: Inherited Rental Portfolio

An heir inherits three rentals from a parent who bought them between 1996 and 2004. The parent's combined adjusted basis was $186,000 after decades of depreciation. Date-of-death appraised value is $2,340,000.

The heir obtains qualified appraisals establishing the $2,340,000 value and the land allocation of $445,000, leaving $1,895,000 of depreciable basis across the three properties.

Straight-line depreciation alone on the new basis is $68,909 annually, against roughly $4,000 the parent had been claiming.

Assume properly documented studies allocate $492,700 of the $1,895,000 depreciable basis to five-year and 15-year components, or 26%. The remaining $1,402,300 stays in its appropriate building class. These inherited components do not qualify for bonus depreciation merely because the heir has a new Section 1014 basis; the IRS used-property test specifically excludes that basis. The studies must reconcile to the estate valuation and support each asset classification.

The $492,700 of shorter-life basis is recovered under applicable regular MACRS schedules rather than expensed all at once as bonus depreciation. The exact first-year amount depends on the five-year versus 15-year split, placed-in-service months, conventions, and business use. If the heir's spouse qualifies as a real estate professional, that alone does not make the loss nonpassive: material participation in the rental activity must also be established, and any election to treat multiple rental interests as one activity must be valid and documented.

Do not multiply the full $492,700 reclassification by a marginal rate to estimate first-year savings. Compare the inherited property's regular MACRS schedule with the supported cost-segregated schedule year by year, apply basis and loss limitations, subtract study and filing costs, and model a later sale. That comparison shows whether acceleration is valuable for this heir.

What to gather before commissioning a study

Deed, title history, percentage inherited, and any prior co-ownership or community-property records.
Estate Form 706 and Form 8971 Schedule A if supplied; otherwise the date-of-death or applicable alternate-date appraisal and valuation workpapers.
The decedent's and heir's depreciation schedules, capital-improvement records, and land allocation.
Rental agreements, listing and renovation dates, occupancy records, and evidence showing when the heir's property was ready and available for rent.
Separate invoices and placed-in-service dates for improvements the heir bought or constructed after inheritance.
Current return, passive-income and Form 8582 schedules, basis and at-risk records, and expected hold or sale period.

Failure points to resolve in the return review

Calling inherited components bonus-eligible. A Section 1014(a) basis is excluded from the used-property acquisition test even when the heir never used the assets.
Depreciating land or the wrong ownership share. Reconcile component totals to the heir's actual inherited interest and supported land value.
Confusing a deed with an inherited entity interest. An inherited partnership or LLC interest does not automatically reset every underlying asset's common inside basis; review the entity's basis-adjustment rules separately.
Using the death date for a home not yet available for rent. The placed-in-service date follows when the property becomes ready and available for the income-producing use.
Quoting tax savings before testing losses. Passive, at-risk, basis, and disposition rules can delay or change the value of accelerated deductions.

AE can reconcile the estate basis with a proposed study, model regular MACRS acceleration, and determine what reaches the return.

Frequently Asked Questions

Can I do a cost segregation study on property I inherited?

Yes. A defensible study may identify shorter-life assets within the heir's inherited depreciable basis. Land, estate-value consistency, study cost, and the heir's ability to use losses must be reviewed; the inherited Section 1014 basis generally does not qualify for bonus depreciation.

Does the depreciation schedule start over when I inherit?

Generally, the heir uses a new depreciation schedule rather than the decedent's remaining schedule. The heir's placed-in-service date is when the property is ready and available for rental use; it is not automatically the date of death if the property is not yet available for rent.

Is inherited property eligible for bonus depreciation?

Generally no for the inherited Section 1014(a) basis. The IRS used-property acquisition test expressly excludes property whose basis is determined under Section 1014(a), even when the heir never used it before. A study can still support regular MACRS acceleration; separately acquired improvements require their own eligibility analysis.

What if no estate tax return was filed?

Document the applicable inherited basis, generally with a date-of-death appraisal when no estate-value statement is available. A later reconstruction may be possible but can be harder to substantiate. Review whether an estate return, alternate valuation, or other basis exception applies.

What happens to the decedent's suspended passive losses?

Section 469(g)(2) generally allows the decedent's suspended passive losses on the final return only to the extent they exceed the increase in basis of the activity's property at death. The outcome requires a property-by-property basis and loss calculation, not an assumption that every suspended loss disappears.
