Were exterior fire-alarm systems installed on a federal project telephone or telegraph lines, or taxable real-property improvements?

Short answer They were real-property improvements. California rejected telephone-or-telegraph-line treatment and taxed the contractor's purchase of the system components.

Disclaimer: This April 14, 1966 letter addresses several unrelated federal-project classifications; this page focuses only on exterior fire-alarm systems, not lamps, power panels, transformers, or 400-cycle generators. The source applies historical statutory and Ruling 12 classifications. CDTFA says statutory law controls if it conflicts with an annotation. System design, line type, attachment, project function, contractor role, and current construction-contract law can change the result.

Plain-English summary

The Board reviewed whether exterior fire-alarm systems could be classified like telephone or telegraph lines under the historical statute.

It rejected that classification and treated the systems as improvements to real property under section 6384. The sale of the system components to the contractor was therefore taxable.

The same letter decided several other electrical classifications, but those issues are outside this annotation.

STATE OF CALIFORNIA

565.0280

STATE BOARD OF EQUALIZATION
April 14, 1966
Dear Mr. REDACTED TEXT,
The contentions raised in our meeting in Sacramento on April 6, 1966 have been thoroughly reviewed and discussed with tax counsel in charge of the taxing programs directly involved with classifications of the items in question. Our conclusions regarding these are as follows: It is our position that incandescent, florescent and mercury vapor lamps are part of the fixtures in which they are installed and become improvements to real property under Section 6384 of the law. This is based upon the "unit of use" theory. Accordingly, it is our position that the sale of these lamps to the contractor is a taxable event. As stated at the hearing, we believe transformers and power panels used exclusively to supply electrical energy to machinery and equipment are properly classified as machinery and equipment under Sales and Use Tax Ruling 12. However, we believe a minimus use of such power for lighting does not destroy the classification as machinery and equipment. A maximum of 5 percent non-machinery and equipment use is allowable. We have advised our audit staff that the ampere load may be used as a criterion to determine use. We have considered at some length the proper classification of exterior fire alarm systems. It was ultimately concluded that such systems are not properly classified as "telephone or telegraph lines" as those terms are used in Section 105 of the Revenue and Taxation Code. Accordingly, we believe they are improvements under Section 6384 and that the sale of the components thereof to the contractor is the taxable event. We believe the 400 cycle generators used to produce power for high torque tools are properly classified as machinery and equipment under Ruling 12. We have directed our audit staff to make a reaudit on this basis. If you have further questions in this area, you may contact our district office or feel free to write to me. Very truly yours Jack D. Paulson Associate Tax Counsel JDP:hm [lb]
