Hospital Corporation of America: Why ITC Rules Still Matter

Why does modern cost segregation still rely on rules originally developed for the Investment Tax Credit? Hospital Corporation of America v. Commissioner, 109 T.C. 21 (1997), provides an important part of the answer. The 2025 IRS Cost Segregation Audit Technique Guide describes HCA as a landmark decision and explains that the court concluded prior precedent used to distinguish tangible personal property from structural components remained applicable under ACRS and MACRS. The case therefore reaches beyond the individual hospital assets that were disputed. For CostSegRx, its lasting importance is that modern engineering-based cost segregation continues to operate within a property-classification framework with roots that predate MACRS.

Key Takeaways

• HCA addressed whether older Investment Tax Credit property-classification principles remained relevant under ACRS and MACRS.
• The Tax Court rejected the argument that using different recovery periods for qualifying components amounted to prohibited component depreciation.
• HCA preserved the relevance of earlier tangible personal property and structural component authorities when distinguishing § 1245 property from § 1250 property.
• The ATG applies the HCA framework to systems such as electrical distribution that may contain both § 1245 property and § 1250 property.
• The IRS acquiescence accepted an important HCA legal principle without accepting every individual asset determination made by the court.
• A single construction system can contain costs requiring separate classification when identifiable portions serve qualifying property.
• HCA helps explain why modern cost segregation still relies on classification authorities developed before MACRS.

What Was Hospital Corporation of America v. Commissioner About?

Hospital Corporation of America v. Commissioner involved the classification of property associated with hospital facilities.

According to the ATG, HCA and its subsidiaries constructed, owned, and operated hospitals and medical office buildings. The taxpayer classified certain property as tangible personal property and claimed depreciation deductions using a 5-year recovery period.

The IRS challenged classifications involving a number of items.

The Service's position included the argument that certain disputed property constituted structural components that should be depreciated over the same recovery period as the related buildings.

But the dispute involved a larger legal question.

Could the taxpayer continue using classification principles developed under the former Investment Tax Credit when determining property classifications under ACRS and MACRS?

That question made HCA much more important than a case about hospital construction.

The ATG describes the decision as a landmark case.

The reason is that HCA helped confirm which body of classification authority continues to matter when determining whether property falls within § 1245 or § 1250.

This article focuses specifically on that legal bridge. CostSegRx also maintains a broader discussion of how the HCA decision changed cost segregation for investors.

What Did the IRS Argue in HCA?

The ATG explains that the Service made several arguments concerning the taxpayer's classifications.

One was that many of the disputed items constituted structural components and therefore should be depreciated over the same recovery period as the related buildings.

Another involved component depreciation.

Before ACRS, component depreciation could allow different components of a building to be depreciated separately over different useful lives.

Congress eliminated component depreciation under ACRS.

The Service argued that allowing the taxpayer to separate certain building-related costs and depreciate them over different recovery periods effectively amounted to prohibited component depreciation.

The Service also argued that the tests developed under the Investment Tax Credit should not control classification under ACRS and MACRS.

The Tax Court rejected that broader position.

That distinction is important.

Cost segregation does not mean taking pieces that are properly classified as building components and simply assigning them shorter recovery periods.

The underlying question is whether particular property is actually § 1245 property rather than § 1250 property.

If property is properly § 1245 property, recognizing it separately is not the same thing as using component depreciation to shorten the life of property that remains part of the building.

That difference is foundational to cost segregation.

Why Do Old Investment Tax Credit Rules Still Matter?

The answer comes from the relationship between the statutory definitions.

The ATG explains that § 1245 property includes tangible personal property and certain other tangible property.

Treasury Regulation § 1.1245-3 refers back to definitions contained in Treasury Regulation § 1.48-1, including tangible personal property, other tangible property, buildings, and structural components.

Those regulations were associated with the former Investment Tax Credit.

The Tax Court in HCA concluded that Congress did not intend the adoption of ACRS to redefine § 1250(c) in a way that would transform property historically treated as § 1245 property into § 1250 property.

As summarized by the ATG, precedent developed to determine whether property constituted eligible § 38 property for Investment Tax Credit purposes therefore remained applicable in determining whether property constitutes § 1245 property under ACRS and MACRS.

This is a critical piece of the legal architecture behind cost segregation.

Modern MACRS recovery periods did not erase the earlier classification framework.

That is why older cases, regulations, revenue rulings, and legislative history continue appearing throughout the Cost Segregation Audit Technique Guide.

For investors, it can initially seem strange to encounter decades-old Investment Tax Credit authorities in a modern depreciation study.

HCA helps explain why they are there.

How Does HCA Apply to Electrical Distribution Systems?

The ATG gives a particularly useful application involving electrical distribution systems.

Electrical systems illustrate why engineering-based classification cannot always stop at a contractor category such as “electrical.”

A building may have general electrical infrastructure serving ordinary building functions.

The same project may also contain electrical infrastructure associated with particular qualifying machinery or equipment.

The ATG explains that, pursuant to HCA, methodologies previously used to allocate building costs between Investment Tax Credit property and structural components can be used to segregate § 1245 property from § 1250 property.

The ATG's electrical distribution discussion recognizes that a system can have characteristics of both § 1245 and § 1250 property.

This connects directly to CostSegRx's article on MEP systems and cost segregation.

Calling the entire system “electrical” does not answer the classification question.

CostSegRx engineers may need to understand what particular circuits or distribution components serve, where they originate and terminate, and how they relate to the qualifying equipment and the building.

The engineering work supports the allocation because the legal framework allows qualifying property to be identified rather than forcing every cost within a building trade into one recovery class.

Did the IRS Agree With Everything the Tax Court Decided in HCA?

No.

This is one of the most important nuances in the ATG's discussion of HCA.

The ATG explains that the Service acquiesced to the Tax Court decision concerning the continued applicability of the Investment Tax Credit definition of tangible personal property for purposes of determining depreciation under ACRS and MACRS.

But the ATG also states that the Service did not agree with the court's determinations regarding whether the individual assets at issue were tangible personal property.

Those are two different propositions.

The first concerns the legal framework.

The second concerns the classification of specific assets under that framework.

For CostSegRx, that distinction is essential.

HCA should not be converted into an asset list where an item that received a particular treatment in the case automatically receives that treatment in every other property.

The same caution applies throughout this ATG series.

Court cases provide authority and principles.

The actual property still needs to be investigated.

An asset may have a similar name but a different function, installation, attachment, structural relationship, or use.

This is why CostSegRx engineers document the physical facts rather than relying on a case name as a substitute for analysis.

How Can HCA Affect the Analysis of a Building System?

Illustrative example only. Actual asset classifications, recovery periods, costs, depreciation deductions, and tax results depend on the specific property, engineering analysis, documentation, applicable authority, and taxpayer circumstances.

Assume a commercial facility undergoes a major construction project that includes $600,000 of electrical distribution work.

The contractor's schedule contains one broad line item:

“Electrical distribution: $600,000.”

An accounting-only approach might be tempted to treat that amount as one homogeneous system.

An engineering review may reveal something different.

A portion of the system provides ordinary building power for lighting, convenience receptacles, HVAC, and other general building functions.

Another identifiable portion may provide dedicated electrical distribution associated with qualifying machinery or equipment.

The existence of that second portion does not mean every electrical cost becomes § 1245 property.

Likewise, the fact that the electrical infrastructure was installed during construction does not necessarily mean every dollar must remain § 1250 property.

The appropriate analysis requires identifying what the system serves and applying the relevant authority.

That is where HCA becomes practically important.

The ATG explains that methodologies historically used to allocate costs between ITC property and structural components can continue to inform the segregation of § 1245 property from § 1250 property.

CostSegRx engineers can support that process by tracing systems, reviewing electrical drawings, identifying dedicated service, examining equipment connections, and documenting the relationship between infrastructure and the property it serves.

The classification follows the evidence.

What Is the Most Important Lesson From HCA?

The most important lesson from Hospital Corporation of America is not that every asset involved in the case should receive the same classification in every cost segregation study.

Its larger significance is the legal framework.

HCA confirmed that the transition to ACRS and MACRS did not simply erase the earlier body of authority used to distinguish tangible personal property from structural components.

That is why modern cost segregation still encounters regulations and cases originally developed around the Investment Tax Credit.

It also explains why classification requires more than looking up a current MACRS recovery period.

First, the property itself must be properly classified.

Then the applicable recovery period follows from that classification.

For CostSegRx engineers, this reinforces the importance of identifying individual assets and systems, understanding what they serve, documenting their physical characteristics, and applying the appropriate classification authority.

It also reinforces an important limit.

The IRS's acquiescence to HCA's broader legal principle should not be confused with agreement on every individual asset determination made by the court.

Modern cost segregation did not invent a new asset-classification system. HCA confirmed that the older tangible personal property framework remains relevant to determining § 1245 property under ACRS and MACRS.
