Central Citrus Co. v. Commissioner

Where this comes from

Central Citrus operated a citrus processing plant in Arizona. About one-sixth of the facility consisted of insulated sweet rooms. These controlled-atmosphere rooms maintained precise temperature and humidity to process citrus fruit. Inside and serving those rooms were blowers, coolers, transformers, and dedicated electrical distribution.

The company claimed the items serving the sweet rooms as tangible personal property, eligible for faster depreciation and investment tax credit. The IRS disagreed. The Tax Court had to sort process-specific equipment from general building infrastructure.

What the court decided

The Tax Court split the plant's components along a functional line.

The items dedicated to the sweet rooms qualified as Section 38 personal property. The blowers and coolers in the rooms, the sweet-room transformers, and the electrical distribution and outlets serving only the production process all qualified. These items existed for one reason: to support the controlled-atmosphere citrus processing. That sole purpose separated them from the building.

The general electrical infrastructure did not qualify. The main power panel, the main step-down transformer, and general lighting and outlets served the plant as a whole. Because they were not tied to the production process, they were structural components on the slow schedule.

How it shows up in a study

Central Citrus is cited in cost segregation reports for food processing plants, agricultural facilities, and any building with process-dedicated climate or electrical systems. It supports the argument that equipment serving a specific production activity is personal property, even when it is installed in or adjacent to a building.

The sole-justification test this case applies is the same framework used in later cases and in the IRS Audit Technique Guide. A strong study documents what each system does, who it serves, and why it is connected to the production process rather than to general building functions.

What it does not mean

Central Citrus does not say that all climate equipment is personal property. The general electrical, the main transformer, and the general lighting all stayed structural. The win was narrow: only the items with a sole connection to the production process qualified.

The case also does not help retail settings. A later case, Circle K, applied the same test to cold storage in a convenience store and reached the opposite result because the store was selling, not processing. Function and context both matter, and this case is strong support only when you can document a clear sole-process connection.
