Cost Segregation Basis Allocation for Acquired Property

When commercial real estate is acquired for a lump-sum purchase price, cost segregation involves more than identifying which assets are building components, land improvements, or personal property. The purchase price itself must also be allocated among the property acquired.

The IRS Cost Segregation Audit Technique Guide explains that acquired property may include land, buildings, land improvements, and personal property purchased together. Unlike new construction, the available historical construction records may be limited or nonexistent. That changes the analytical problem from simply tracing actual construction costs to determining supportable values for the property that existed on the acquisition date.

The direct answer is that the ATG generally frames acquired-property basis allocation around the fair market values of the assets at acquisition. Land must be separated from depreciable property, and the depreciable components must be valued based on their actual age, condition, physical depreciation, and functional or economic obsolescence rather than treated as if they were new.

Key Takeaways

• Acquired-property basis allocation generally starts with fair market value at the acquisition date.
• Land must be separated from depreciable property before the remaining basis is allocated.
• Existing assets should be valued as acquired, not simply at their replacement cost when new.
• Field inspection and available acquisition records help establish what property actually existed and its condition.
• Written purchase-price allocations can materially limit what a later cost segregation study can change.
• The ATG criticizes using a simple pro-rata step-up merely to force estimated costs to match the purchase price.
• For acquired property, engineering and valuation must connect the physical facts to the total acquisition basis.

How Does the ATG Approach Basis Allocation for Acquired Property?

The ATG explains that cost segregation can perform two related functions in an acquisition: determining the classification of property and allocating the cost basis among the acquired assets. When a group of assets is acquired for one lump-sum price, the allocation generally depends on determining the fair market values of the property acquired.

This is different from a newly constructed project. In new construction, contemporaneous contracts, payment applications, invoices, change orders, and other records may provide direct evidence of construction cost. An acquisition may provide much less historical information. The ATG therefore points toward appraisal practices and construction cost estimating techniques when determining the values of acquired assets.

For an acquisition containing both depreciable and nondepreciable property, Treasury Regulation § 1.167(a)-5 provides an important underlying rule. The depreciable basis is apportioned by reference to the relative value of the depreciable property compared with the value of the entire property at acquisition. The ATG uses that regulation as part of its examination framework for acquired real estate.

The distinction matters because the ATG itself is examination guidance, not controlling legal authority. The regulation supplies the underlying apportionment rule. The ATG explains how examiners should evaluate studies applying that rule in the context of acquired property.

Why Does Land Value Matter Before Depreciable Assets Are Allocated?

Land is nondepreciable, so separating its value from the total acquisition price is a fundamental step in determining the depreciable basis available for the other property.

The ATG tells examiners to consider whether land has been properly valued and discusses determining the fair market value of land based on its highest and best use as though vacant. It also explains that the value of the total real estate less the value of the land produces the contributory value of the improvements.

This is important because land cannot simply become whatever amount is left after a study assigns values to buildings, land improvements, and personal property. If the depreciable components are overstated first and land is treated as a residual, the resulting allocation can shift too much of the acquisition price into depreciable property.

For a property owner, the lesson is straightforward: the cost segregation analysis and the land valuation cannot be treated as unrelated calculations. The allocation needs to make sense as one economic picture of the property acquired.

Why Must Existing Property Be Valued as Acquired?

An acquired asset is not automatically worth what a comparable new asset would cost to construct or install.

The ATG explains that when actual construction cost information is unavailable, replacement cost new may be estimated using construction cost data and appraisal techniques. Those estimates are then adjusted for the asset's age and condition at the acquisition date, including physical depreciation, functional obsolescence, and economic obsolescence.

The ATG refers to this adjusted concept as replacement cost new less depreciation, or RCNLD. The combined RCNLD of the buildings, land improvements, and personal property, together with the fair market value of the land, should reasonably relate to the total purchase price.

The adjustment matters because different assets within the same acquisition may have very different histories. A building structure, parking lot, HVAC component, electrical system, specialized equipment item, and interior finish may have been installed at different times, experienced different levels of use, and have different remaining economic utility.

That is why a study cannot reasonably assume that every component has deteriorated at the same rate simply because all of the property was purchased on the same day.

What Evidence Matters When Original Construction Records Are Missing?

When historical construction records are incomplete, the physical property itself becomes an important source of evidence.

The ATG identifies field inspection as particularly important for used or acquired property when drawings and specifications are limited. A field inspection can document the building's construction, materials, systems, assets, land improvements, and their condition at the time relevant to the study.

Available records also remain important. The ATG discusses purchase agreements, appraisals, escrow documents, payment records, historical construction records, contract files, and record or as-built drawings as potential sources for understanding what was acquired and how it should be valued.

CostSegRx engineers approach this as an engineering reconstruction of the property as acquired. The questions include what existed, what condition it was in, whether systems had been replaced or modified, what documentation supports those observations, and whether the cost estimates reflect the actual property rather than a hypothetical new building.

This is an important distinction between cost development and asset classification. Establishing a supportable value for an asset does not by itself determine its depreciation classification, and identifying an asset does not by itself establish its correct value. Both questions require support.

What If the Buyer and Seller Already Allocated the Purchase Price?

A written purchase-price allocation can materially affect what a later cost segregation study is able to change.

The ATG tells examiners reviewing acquired property to examine the acquisition documents and determine whether the buyer and seller agreed to a written purchase-price allocation. It discusses Internal Revenue Code § 1060 in connection with applicable asset acquisitions and separately discusses the Peco Foods case.

In Peco Foods, Inc. v. Commissioner, the taxpayer purchased two poultry processing plants in transactions the ATG identifies as applicable asset acquisitions under § 1060. The buyer and seller had entered into written agreements allocating the purchase prices among the acquired assets. Peco Foods later obtained a cost segregation study that attempted to subdivide and recharacterize parts of those allocations.

The Tax Court held that Peco Foods was bound by the clear and unambiguous allocation schedules and could not use the later cost segregation study to depart from the agreed characterization of those assets. The ATG uses the case when discussing examination of contractual purchase-price allocations.

That does not mean Peco Foods automatically controls every commercial real estate purchase. The ATG expressly notes that it is unclear whether the holding would apply to acquisitions other than applicable asset acquisitions under § 1060.

For investors, the important point is that acquisition documents should not be viewed as irrelevant paperwork once a cost segregation study begins. A contractual allocation can become part of the tax framework within which the later engineering analysis must operate.

Why Does the ATG Criticize a Pro-Rata Step-Up?

The ATG does not treat a simple mathematical adjustment as a substitute for determining why estimated property values fail to reconcile with the acquisition price.

Its acquired-property discussion includes an example in which estimated RCNLD for the improvements and personal property was lower than the portion of the purchase price assigned to those assets. The study multiplied the estimated values by a common factor so the totals would equal the purchase price.

The ATG tells examiners to scrutinize that type of adjustment. It states that applying a pro-rata step-up factor to the estimated costs of the improvements and personal property merely to reconcile to the purchase price is not an acceptable method of establishing the depreciable basis of the acquired items.

Instead, the difference should be investigated. The ATG identifies potential causes including an incorrect land value, unidentified assets or components, inaccurate cost estimates, incorrect depreciation or obsolescence factors, and failure to account properly for indirect costs.

This distinction is important from an engineering perspective. Reconciliation is a diagnostic tool, not permission to force every component upward by the same percentage. When the numbers do not reconcile, the discrepancy may reveal a problem with the underlying facts or methodology.

What Should a Commercial Property Owner Take From This?

Value the property as acquired, not as if it were new.

That is the central engineering lesson in the ATG's acquired-property discussion. A defensible allocation begins with the actual acquisition and works back into the assets that existed on that date.

CostSegRx engineers examine the physical property, available drawings and records, acquisition documents, appraisals, system condition, asset age, modifications, deterioration, and other relevant evidence before developing supported component values. Replacement cost estimates can be useful, but they need to be adjusted to reflect the property that was actually purchased.

The resulting allocation should also make sense as a whole. Land, buildings, land improvements, and personal property are not independent estimates that can be developed without regard to the total transaction. The individual values need to connect back to a supportable acquisition basis.

For investors, this means an acquired-property cost segregation study should not be evaluated only by how much basis it places into shorter recovery periods. A more meaningful question is whether the study explains how the purchase price was allocated, how the assets were identified and valued, what evidence supports the analysis, and why the final numbers reconcile to the economics of the acquisition.

The IRS ATG does not prescribe a single cost segregation methodology for every acquired property. It does, however, give examiners a framework for evaluating whether the allocation is supported. That framework places significant weight on fair market value, land valuation, actual property condition, acquisition documents, engineering evidence, and reconciliation rather than on a desired depreciation result.
