When was jobsite work on turbine components taxable assembly rather than installation?

Short answer Attaching components directly to realty was installation, but assembling or processing personal-property components before affixation was taxable. A 1987 note made Regulation 1521 control any conflicting cost measure.

Currency note: this ruling is from 1987
Subsequent statutory amendments, regulation changes, court decisions, or later rulings may have changed the analysis. Treat this page as historical context, not current tax advice. Verify current law before relying on any specific rule, rate, or position mentioned here.
Disclaimer: The underlying memorandum is dated April 7, 1966, but the official PDF incorporates a signed July 2, 1987 correction stating that Regulation 1521(b)(2)(B)2 supersedes the memorandum's cost paragraph to the extent of conflict. The February 18 request, March 31 follow-up, Chicago early-response request, and returned project-data attachment are not reproduced in the official PDF. The source twice prints “date” where it describes the amount and volume of submitted project information; that wording is preserved as a source defect. The correction controls the published measure analysis, so its date is used here. The same corrected memorandum is separately published under Annotation 190.2300.

Plain-English summary

Turbines, pump-turbines, Kaplan turbines, and governors were fixtures that became part of real property. The installer was their retailer.

Jobsite work that only attached a component to realty before any further assembly was installation labor. Jobsite assembly or processing of personal-property components before their affixation was taxable.

The 1966 memorandum described a fabricated-cost measure including materials, fabrication labor, overhead, indirect costs, and taxable pre-attachment jobsite assembly. A signed July 2, 1987 correction states that Regulation 1521(b)(2)(B)2 supersedes that paragraph wherever the two conflict.

Common questions

Were turbines and governors fixtures?

What jobsite work was taxable?

Assembly or processing of personal-property components before affixation.

Not where it conflicts with Regulation 1521(b)(2)(B)2, according to the incorporated 1987 correction.

Your memo of 2-18-66, and follow-up of 3-31-66

Turbines, Pump-turbines and Kaplan turbines and Governors, herinafter collectively called “turbines,” are “fixtures” under ruling 11. They become a part of the real property. As the installer is the retailer, his gross receipts must be ascertained. The fixtures are partially manufactured at the factory, and shipped unassembled or as subassemblies to the jobsite. If the final assembly at the jobsite involves only the attaching of components to real property prior to any further assembly of personal property components, tax does not apply to such installation labor. If, however, there is any jobsite assembly or processing of tangible personal property prior to its being affixed to real property, charges for such assembling or processing would be subject to tax. The measure of tax is the selling price of these components and subassemblies, which, if not stated in the contract (unit prices quoted include installation), is the “fabricated cost” thereof. This is the sum of the following: Cost of materials, cost of fabrication labor, overhead and indirect costs prorated to the fabrication of the fixtures sold, i.e. the components or subassemblies in the state of completion at the time they become affixed to real property. In addition, tax would be measured by the value of any jobsite labor of assembly or processing of personal property prior to its being affixed to real property. * The foregoing may be considered rather brief in view of the size of the project and the amount of date submitted. The request of Chicago for an early response, and your follow-up of March 31, prevents us, however, in view of other work that cannot be put off, from spending the time reasonable required to make a detailed analysis and study of the large volume of date submitted, which is returned herewith.. We shall, of course, be glad to confer with Mr. --- --- or any other interested party regarding the matter.
