Circle K Corp. v. Commissioner

Where this comes from

Circle K Corporation operated a chain of convenience stores. Each store had purpose-built cold storage rooms and roof-mounted air conditioning units. Circle K argued that both items qualified as personal property because they were designed specifically for temperature control.

The IRS disagreed. The case went to the U.S. Tax Court in 1982.

What the court decided

The Tax Court ruled against Circle K on both items. The cold storage rooms and the roof-mounted A/C units were structural components under Section 1250.

The court's reasoning turned on the sole-justification test. That test asks whether a building system exists solely to serve another piece of equipment or a specific production process. Circle K was not processing food. It was selling it. Storing cold products for retail sale is a building function, not a production process. That distinction was enough to take the cold storage rooms out of the personal property category.

The same logic applied to the A/C units. Roof-mounted units serving the retail space conditioned the building for occupants, not for a manufacturing or distribution process.

How it shows up in a study

Circle K appears in cost segregation reports to mark a limit. When a building has cold storage in a retail context, the study explains why this case applies or why it does not.

The contrast with Munford is deliberate. Munford involved refrigerated warehousing for distribution. That context supported the personal property argument. Circle K involved retail selling. That context did not. Citing both cases shows that the study understands the spectrum and is not overclaiming.

The IRS has issued its own guidance disagreeing with the cold-storage part of this opinion, but the adverse result still stands as a real risk in retail settings.

What it does not mean

Circle K does not say that all cold storage is structural. Munford remains good law for refrigerated warehousing and distribution facilities. The result depends on the business activity, not just the equipment.

It also does not say that retail buildings can never have personal property. Many components in a convenience store qualify, from dedicated process equipment to site improvements. Circle K is about the specific items at issue, cold rooms and building HVAC, in a specific context, retail selling. It is a limit, not a blanket rule.
