Do a manufacturer's transformer, rectifier, and bus bars qualify for the sales tax manufacturing equipment exemption, or are they taxable real-property electrical fixtures?

Plain-English summary

A manufacturer used three pieces of electrical equipment as part of a chemical-reaction manufacturing process: a transformer (outside the building, stepping utility power down to the voltage the process needs), a rectifier (inside the facility, converting AC to DC), and bus bars (holding conductors that deliver the finished power to the process). The manufacturer argued these components were "dedicated solely to the manufacturing process" and should qualify for the manufacturing equipment exemption.

The Commission confirmed the general 3-part exemption test under Utah Code Ann. § 59-12-104(14) -- the component must (1) have an economic life of 3+ years, (2) be used in a Utah manufacturing facility to make an item sold as tangible personal property, and (3) be used in the manufacturing process -- but focused on a separate, threshold question: do these electrical components even count as "machinery and equipment" in the first place, or are they part of the building's real property?

Under Utah Admin. Code R865-19S-85(A)(3)(b), "machinery and equipment" specifically excludes gas, water, or electricity systems that count as real property improvements. But Subsection (B) carves out an important exception: if a separate gas, water, or electrical supply line is installed solely for the operation of the manufacturing equipment, that supply line is treated as an accessory to the equipment, not real property.

The key distinction the Commission drew is between "dedicated to the manufacturing process" (the manufacturer's phrase) and "installed solely for the operation of the equipment" (the rule's actual standard) -- these are not the same thing:

• If the electrical components also provide lighting for the manufacturing facility, they might still be broadly "dedicated to the manufacturing process," but they are not installed solely for the equipment's operation -- disqualifying them.
• If any of the electricity the transformer converts is used for a purpose outside operating the manufacturing equipment, the transformer itself fails to qualify as "machinery and equipment."
• But if the electrical components sit on a separate line used only to run qualifying manufacturing equipment, the components themselves are exempt.

The Commission couldn't resolve, on the letter alone, whether this particular manufacturer's supply line was truly separate and solely dedicated -- that's a fact question subject to audit review and verification -- but it laid out the exact framework the manufacturer needs to apply.

What this means for you

Manufacturers with dedicated electrical infrastructure (transformers, rectifiers, switchgear, etc.)

"Dedicated to the manufacturing process" isn't the legal test -- "installed solely for the operation of the manufacturing equipment" is, and it's stricter. If any part of that electrical infrastructure also powers lighting, HVAC, or anything else not part of running the qualifying equipment, the whole component risks being reclassified as taxable real property rather than exempt equipment.

Businesses documenting manufacturing exemption claims for electrical equipment

Keep clear documentation (wiring diagrams, load studies) showing that a supply line serves qualifying manufacturing equipment exclusively. Because this is a fact question subject to audit verification, the burden will fall on you to demonstrate the separateness and exclusivity of the line if challenged.

Accountants and tax professionals

This ruling is a useful, precise statement of the accessory-vs-real-property-system distinction for electrical (and by analogy, gas/water) supply infrastructure under R865-19S-85(B) -- a narrower and more mechanical test than a general "is this used for manufacturing" inquiry.

Common questions

Q: Does an electrical component qualify for the manufacturing exemption just because it's used in the manufacturing process?
A: Not necessarily. It must be installed on a supply line used solely to operate qualifying manufacturing equipment -- any other use, like facility lighting, disqualifies it.

Q: What if only part of the electricity from a transformer goes to something other than the manufacturing equipment?
A: Even a partial other use is enough to disqualify the transformer from being treated as exempt "machinery and equipment."

Q: Who decides whether a supply line is truly "separate and installed solely" for the equipment?
A: That's a fact-specific determination subject to review and verification by the Commission's auditors -- it can't be resolved in the abstract by an advisory opinion alone.

Q: Does this ruling apply to my manufacturing facility's electrical equipment?
A: No. It binds the Commission only for the requesting manufacturer and the facts described. Another taxpayer can't rely on it as binding, though it may carry some persuasive weight in a dispute with closely similar facts.

REQUEST LETTER

September 8, 1998

Dear Commissioners:

Regarding: Sales or use tax exemption for new or
expanding operations and normal operating replacements.

One of our clients, who is a manufacturer, has among
its machinery and equipment the following items:

1. A transformer,
   located outside the manufacturing facility, connected to equipment within the
   building by power lines which run through the walls of the building. The
   transformer transforms the voltage in the power received from the utility
   company to the voltage level that is required by the manufacturing process.

2. A
   rectifier, located inside the manufacturing facility, which is connected to the
   transformer and other equipment by power lines. The rectifier changes the
   electrical current from AC to DC.

3. Bus bars
   which hold conductors in place. Once the transformer and the rectifier have
   done their work, the power is delivered to the manufacturing process by the
   conductors.

The application of electricity is an essential part of
the manufacturing process, and the pieces of equipment mentioned above are
dedicated solely to that manufacturing process. Electricity, in this instance,
is used to create a chemical reaction necessary to the production of the
product.

Under the circumstances, it seems reasonable that
these pieces of equipment would qualify for the exemption. We would appreciate
your opinion.

Sincerely,

NAME

RE: Application
of the Manufacturing Equipment Exemption to Electrical Components

Dear NAME,

We have received your request concerning the
application of the manufacturing equipment exemption to components installed to
provide electricity. To qualify for the
manufacturing equipment exemption, Utah Code. Ann. '59-12-104(14) requires that the components be
machinery and equipment that (1) have an economic life of three or more years,
(2) are used in a manufacturing facility in the state to manufacture an item
sold as tangible personal property, and (3) are used in the manufacturing
process. You have represented that the
electrical components meet all these criteria if such electrical components are
deemed Amachinery or equipment.@

Machinery and Equipment. Assuming
that all the other criteria are met, whether the electrical components are
deemed Amachinery and equipment@ will determine if the electrical components qualify for the
exemption. Utah Admin. Code
R865-19S-85(A)(3)(b) provides that Amachinery
and equipment@ does not Ainclude
gas, water, or electricity systems that constitute real property improvements
as provided in B.@ Subsection
(B) of the rule provides as follows:

The sales and use tax exemptions ... apply only to
purchases or leases of tangible personal property used in the actual
manufacturing process. The exemptions do not apply to purchases of real
property or items of tangible personal property that become part of the real
property in which the manufacturing operation is conducted. If a separate
gas, water, or electrical supply line is installed solely for the operation of
the manufacturing equipment, the gas, water, or electrical supply line is an
accessory to the manufacturing equipment rather than a part of the real
property. (Emphasis added).

Thus, the rule provides that electrical components are
deemed Amachinery and equipment@ for purposes of the exemption only if they are installed solely for the operation of the
manufacturing equipment.

You have stated that the electrical components are Adedicated solely to the manufacturing process.@ If the
electrical components provide lighting for the manufacturing facility, they may
be dedicated solely to the manufacturing process, but they are not installed
solely for the operation of the equipment.
Other use not relating directly to the equipment would also disqualify
the electrical components from being deemed Amachinery
and equipment.@ For example,
if any of the electricity that is transformed by the transformer is used for a
purpose outside the operation of the manufacturing equipment, the transformer
is not Amachinery and equipment.@ However, if the electrical
components are installed on a separate line that is used only to operate (i.e.,
run) qualifying manufacturing equipment, the components themselves will also be
exempt.

Whether an electrical supply line is separate and
installed solely for the operation of manufacturing equipment will be based on
all the facts and circumstances, all of which would be subject to review and verification
by our auditors, and, accordingly, cannot be decided here. However, the discussion above should help
you determine whether the electrical components at issue here qualify for the
manufacturing equipment exemption.

Please contact us if you have any other questions.

For the Commission,

R. Bruce Johnson

Commissioner
