Partial Asset Disposition: US Owners’ Tax-Preparer Checklist

Give your tax preparer evidence of what was removed and when, historical basis and depreciation records, and separate replacement records to evaluate a partial asset disposition.[2][3] Disposing of part of a depreciable MACRS building can allow a loss for the retired component’s remaining adjusted basis—even if it was never listed separately. Treasury’s 2014 disposition regulations provide that framework, which IRS examination guidance also explains.[1][2] Depreciation stops on the disposed portion, while the replacement is tracked separately.[2][3]

A renovation alone does not guarantee a deduction. Your preparer must review the disposal, eligibility, supported basis and election requirements.[2] The checklist below is a practical organizing tool, not an IRS-mandated packet.

Check eligibility and election timing first

Provide the existing depreciation schedule so your preparer can verify your depreciable interest and the component’s depreciation method. Eligible interests can include owners, lessors and lessees with depreciable leasehold improvements. These rules apply only to MACRS property; a component depreciated under a pre-MACRS method cannot generate a partial-disposition loss under these rules.[2] Replacing a component of a nondepreciable personal residence does not establish eligibility.[2]

For an ordinary replacement, treatment is generally elective. The election is made by reporting the gain or loss on a timely filed original return, including extensions, for the tax year of disposition—not necessarily the replacement’s placed-in-service year. No separate election form or attached statement is required.[2]

Partial-disposition treatment is required rather than elective for these events:[2]

• Casualties under Section 165.[2]
• Partial dispositions involving nonrecognition under Sections 1031 or 1033.[2]
• “Step-in-the-shoes” transfers under Section 168(i)(7)(B).[2]
• Sales of part of an asset.[2]

Tell your preparer whether the disposition-year original return has already been filed. If an election may have been missed, request qualified review rather than assuming the benefit is lost or an amended return will fix it. CSSI describes possible automatic relief under Section 9100 and potential nonautomatic relief requiring a private letter ruling.[3] The IRS Process Unit’s reference to late elections concerns a transitional Form 3115 (DCN 196) route for tax years beginning 2012–2014, not a current remedy.[2]

Identify the removed component and disposition event

Document the retirement, not simply the renovation. A disposition includes transferring ownership or permanently withdrawing an asset—or part of a building’s structural component—from business or income-producing use.[2]

• What: Identify the building and component, including whether all or only part of the component was removed.[2]
• When: Record the permanent-withdrawal date separately from the replacement’s placed-in-service date.[2]
• How: Explain whether the component was retired, abandoned, scrapped, sold, destroyed or transferred through another transaction.[2]

Attach project descriptions and applicable abandonment, scrap, sale, casualty, insurance, exchange or involuntary-conversion records.[2] Contractor invoices, permits and before-and-after photographs can corroborate the work; SmartAsset recommends these for general improvement recordkeeping, not as an IRS partial-disposition checklist.[5]

Adding rooms or installing walls in previously open space does not, by itself, establish a partial disposition: an existing component or portion must be disposed of.[2]

Gather historical cost and basis evidence

Give your preparer the building’s historical tax records, not only the removal paperwork:[2]

• Original acquisition cost, acquisition date and placed-in-service date.[2]
• Detailed tax depreciation schedules showing accumulated depreciation and separately listed components.[2]
• Records of prior basis adjustments and capitalized improvements.[2]
• Existing cost-segregation reports or other allocation studies. CSSI says these may identify the component’s basis and the recovery period used to depreciate it.[3]

Ask for workpapers distinguishing original or allocated basis, depreciation allowed or allowable through retirement and remaining adjusted basis.[2][3]

If the component was never separately listed

A missing line on the depreciation schedule does not disqualify the component: the Treasury regulations permit partial-disposition treatment even when the disposed portion was not previously identified separately.[1] Provide the building-level records and flag the missing component cost rather than supplying an unsupported estimate.[2][3]

The preparer needs a supported allocation of historical basis—not a direct substitution of the replacement invoice total.[1][2][3] Ask for workpapers identifying the source records, assumptions and reasoning behind the selected method. CSSI recommends documenting the method’s reasoning and applying it consistently.[3]

Keep replacement records separate

Create a separate replacement file containing contracts, invoices, payment evidence and support for the new component’s placed-in-service date.[1][2] The replacement invoice documents new expenditure; it does not automatically establish the old component’s historical basis. Later improvements or additions are treated as separate assets.[1][2]

For a mixed project, separate repair and improvement expenditures for your preparer’s review, as SmartAsset recommends.[5] Replacing a major component or substantial structural part requires capitalization. Replacement costs also must be capitalized when a loss was properly deducted for the old component, regardless of its size or importance.[2]

Have your preparer determine the replacement’s treatment and record its own placed-in-service date and depreciation details; do not assume it is immediately deductible.[2][3]

Request a final depreciation reconciliation

Ask your preparer to reconcile the disposition workpapers, return reporting and ongoing depreciation schedule. The reconciliation should show:[2]

• The disposed component or allocated portion, its basis and accumulated depreciation.[2]
• The resulting gain or loss and the building’s remaining basis.[2]
• The replacement recorded separately, with its own placed-in-service date and depreciation treatment.[2][3]

If partial-disposition treatment is used, confirm depreciation on the retired portion stops.[2][3] Have the preparer connect the workpapers to the appropriate return reporting: IRS guidance discusses Form 4797 for business-use components, with other forms applicable to certain investment-property dispositions or exchanges.[2]

Keep the reconciled schedule with the removal evidence, basis workpapers and separate replacement records so the disposition and subsequent depreciation can be traced.[2][3]
