Whiteco Industries v. Commissioner: the six-factor permanency test
Whiteco Industries v. Commissioner, 65 T.C. 664 (1975), gave tax law its standard test for whether an asset is an inherently permanent structure or tangible personal property — six practical questions about movability that still govern cost segregation classifications.
Whiteco Industries, Inc. v. Commissioner, 65 T.C. 664 (1975), is the case that gave tax law its working definition of "inherently permanent." The Tax Court held that outdoor advertising signs — heavy displays mounted on wooden poles sunk into the ground — were tangible personal property eligible for the investment tax credit, not permanent structures excluded from it. To get there, the court synthesized its prior decisions into six questions about movability that have outlived the credit itself and now anchor the permanency analysis in every cost segregation study.
The dispute
Whiteco built and leased outdoor advertising signs. The displays sat on poles embedded several feet into the ground, sometimes set in concrete or anchored below the frost line. Whiteco claimed the investment tax credit under old Section 38, which required "tangible personal property" — a category the regulations at Treas. Reg. §1.48-1(c) said excluded land improvements and other "inherently permanent structures." The Commissioner argued that anything anchored into the earth that firmly was a permanent structure. The taxpayer answered that the signs were routinely dismantled and relocated as advertising leases ended, highways moved, and markets shifted.
The holding and the six factors
The court sided with the taxpayer. Reviewing its precedents on floating docks, fences, and similar borderline assets, it identified six inquiries:
- Is the property capable of being moved, and has it in fact been moved?
- Is it designed or constructed to remain permanently in place?
- Do the circumstances tend to show the expected or intended length of affixation — is there a real prospect the property will have to be moved?
- How substantial and time-consuming is the job of removal?
- How much damage will the property sustain upon removal?
- What is the manner of affixation to the land?
On the facts, the signs answered nearly every question in the taxpayer's favor: Whiteco moved signs regularly in the ordinary course of business, designed them with relocation in mind, and could dismantle one without destroying it. Embedding poles in the ground was attachment, but not permanence.
The reasoning that matters
Two moves in the opinion do the lasting work. First, the court refused to let physical attachment settle the question — concrete footings and buried poles did not make the signs permanent, because permanence is a judgment about the asset's expected life in place, informed by business reality. Second, the court treated actual history as evidence of character: property that has been moved, in the ordinary course rather than in extremis, is hard to call inherently permanent. No single factor controls, and the test is openly a weighing exercise rather than a bright line.
What it means for claims today
When Hospital Corp of America v. Commissioner, 109 T.C. 21 (1997), held that ITC-era classification principles carry into MACRS, the Whiteco factors became the permanency test for modern depreciation — determining whether an asset is a 39-year structural component or Section 1245 property recoverable over 5, 7, or 15 years under the class lives in Pub 946. The IRS's own Cost Segregation Audit Techniques Guide instructs examiners to apply the six questions, so a study that documents Whiteco facts — how each asset is affixed, whether comparable assets are relocated in practice, what removal would cost and damage — speaks the examiner's own language.
The factors cut both ways. Demountable partitions, signage, and certain equipment foundations often pass; but drywall, permanently set fixtures, and assets that would be destroyed by removal fail, however the study labels them. AmeriSouth XXXII v. Commissioner, T.C. Memo 2012-67, shows the government using the same factors to push apartment components back into the building. The test rewards documented facts, not categories — which is why classification support belongs in the study file from day one.

Frequently asked questions
- What did Whiteco Industries v. Commissioner decide?
- In Whiteco Industries v. Commissioner, 65 T.C. 664 (1975), the Tax Court held that outdoor advertising signs mounted on poles embedded in the ground were tangible personal property, not inherently permanent structures, and so qualified for the investment tax credit. The court distilled six factors — centered on movability, design intent, and damage on removal — that remain the standard permanency test.
- Are the Whiteco factors still used today?
- Yes. Although the investment tax credit was repealed in 1986, the Tax Court held in Hospital Corp of America v. Commissioner, 109 T.C. 21 (1997), that ITC-era classification tests, including the Whiteco factors, still determine whether property is Section 1245 personal property under MACRS. The IRS Cost Segregation Audit Techniques Guide directs examiners to apply the same six questions.
