What is the tax basis of a gifted rental property

A donee's basis often carries over from the donor, with special rules for property received at a loss and for gift tax paid; fair market value alone is not the default.

If you received a rental as a gift and are considering a cost segregation study, Book a Call before ordering one. AE can compare the donor's records, your basis, and the actual tax benefit.

Can I do cost segregation on a gifted rental and claim bonus depreciation?

A study may still be useful, but the gift itself does not create a new fair-market-value depreciable basis or make the donor's carryover basis eligible for bonus depreciation. A cost segregation study classifies supported building costs into appropriate asset classes; it does not manufacture new tax basis. The IRS's used-property bonus test excludes property whose basis is determined in whole or in part by the transferor's adjusted basis. Separately purchased or constructed improvements require their own placed-in-service and eligibility analysis. Publication 551 explains the gifted-property basis rule, while the IRS bonus-depreciation FAQ explains the carryover-basis exclusion.

Which costs could a study actually classify?

Cost layer	Review before commissioning a study
Donor's existing building basis	Obtain the original closing statement, capital improvements, land allocation, and depreciation schedules. A study may identify misclassified assets within supportable remaining basis; it cannot reset that layer to gift-date market value.
Donor's prior cost segregation	Reconcile each asset and depreciation claimed or allowable. Duplicating the donor's five- or fifteen-year allocations would overstate the recipient's deductions.
Recipient's later improvements	Track invoices, dates, and asset descriptions separately. A genuinely new improvement may present a distinct classification and bonus question under the law applicable when placed in service.
Land and personal-use periods	Exclude land from depreciation. If the property was personal before rental use, test the conversion-date lower-of-adjusted-basis-or-fair-market-value rule before allocating depreciable costs.

Whether the recipient continues a donor schedule, starts a separately acquired asset, or needs a depreciation-method correction depends on the transfer and asset history. Do not infer a fresh 27.5-year period or a catch-up deduction from the deed date alone. Publication 946 addresses depreciation methods, placed-in-service facts, and correction procedures.

A decision example: valuable property, limited new basis

Suppose a parent gifts a rental worth $900,000. Its original purchase allocation was $450,000 to the building and $100,000 to land; after $90,000 of capital improvements and $140,000 of depreciation allowed or allowable, the building's adjusted basis before other adjustments is $400,000. The recipient cannot commission a study using $900,000 as depreciable cost. The advisor must first reconcile the donor's original asset basis, prior deductions, and any earlier study. A later $60,000 renovation paid for by the recipient is a separate cost layer to classify on its own evidence. These figures illustrate basis reconciliation, not a calculated deductible amount; gift-tax basis adjustments, transfer terms, and the actual schedules may change the result.

When is a study worth paying for?

Confirm the transfer. A deeded gift, a sale for less than full value, an inherited interest, and a gift of an LLC interest are not interchangeable. Debt assumed or cash paid can change the analysis.
Rebuild basis by asset. Separate land, building, prior improvements, and new recipient-funded improvements; reconcile depreciation allowed or allowable.
Estimate incremental deductions. Ask what a study would change compared with the correct existing schedules, not what percentage of current appraised value could be reclassified.
Test usability and exit cost. Passive-activity limitations may suspend the deduction, while later disposition can trigger depreciation recapture. Review whether the loss is currently usable before paying for a report.

If the donor's records are missing, the first paid task may be basis reconstruction rather than an engineering study. If there is no defensible incremental deduction after fees and tax limitations, the study may not be worthwhile. A donor who is planning the transfer with a Form 8582 carryforward should separately review what happens to suspended passive losses on a rental gift before the deed is signed.

Documents to gather and mistakes to avoid

Gather the deed and gift agreement; donor closing statement and land allocation; donor and recipient Forms 4562, Schedule E, and fixed-asset schedules; invoices for improvements; any prior cost-segregation report; gift-date appraisal and Form 709 if relevant; records of debt assumed or consideration paid; and the recipient's rental placed-in-service date. A common failure is to treat a gift-date appraisal as a new purchase price. Another is to take a new bonus deduction on carryover-basis assets simply because the study now labels some of them five-year property. A third is to ignore passive-loss limits and recapture in the benefit estimate. See the IRS Cost Segregation Audit Techniques Guide for the documentation standard behind a defensible allocation.

Book a Call if you want AE to reconcile the donor's schedules, test whether a study would add a usable deduction, and identify any correction needed before the next return. For a different transfer rule, see our inherited-rental cost segregation guide.

The tax treatment

A donee's basis often carries over from the donor, with special rules for property received at a loss and for gift tax paid; fair market value alone is not the default. This is a federal income tax starting point; the contract, ownership, accounting method, and actual use can change the result. State and local treatment should be checked separately.

The decision to make before filing

Obtain the donor's original cost, improvements, depreciation, and gift-date valuation before claiming deductions. The useful planning step is to resolve the classification while the underlying documents are still available, then reconcile it to the books and the prior-year return. If the transaction spans more than one year, track the opening balance and what happened to it afterward.

Illustrative example

A parent gives an adult child a rental bought years ago and later improved. The child cannot simply depreciate the property's current market value. The donor's cost, improvements, prior depreciation, and gift-date value must be assembled before creating a new schedule.

Records that support the position

Keep gift documents, donor depreciation schedule, appraisals, and Form 709 if filed. Tie amounts on the return to bank activity and the agreement. When several assets, people, or uses are involved, write down the allocation method and apply it consistently. A short dated workpaper is easier to defend than a reconstructed explanation years later.

A common reporting error

Resetting depreciation basis to market value at the gift date generally overstates deductions. Review both sides of the entry: a payment can affect income, basis, liability, or an expense at different times. A correct cash total alone does not establish the correct tax character.

Where to verify the rule

Start with IRS Publication 946: How To Depreciate Property. Its examples and cross-references explain the underlying federal rule; check the current version and any later IRS guidance for the year at issue. For a coordinated review of related deductions and limitations, see Real estate tax planning.

Identify how the property was acquired before calculating depreciation

A gift commonly carries over the donor's basis, with additional rules relevant to losses and certain adjustments. Inherited property generally follows date-of-death value or an applicable alternative valuation, subject to exceptions. Neither rule means that every transfer creates a new purchase basis. Debt, partial sales and entity ownership can add further issues.

Illustrative decision

Two siblings receive comparable rentals: one by lifetime gift and one through an estate. Identical market values do not establish identical tax basis. Obtain the donor's history for the gift and the estate valuation records for the inheritance before preparing depreciation.

Records and decisions to prepare

Identify gift, inheritance or part-sale treatment
Obtain donor basis or estate valuation records
Separate land and improvements
Review prior depreciation and suspended losses
Document the recipient’s rental service date
