At a gas processing plant, is repairing equipment incorporated into realty taxable, are H2S monitors exempt as pollution-control equipment, and is new underground gas-line construction taxable?

Plain-English summary

An oil and gas company asked three separate questions about a gas processing plant.

1. Repairs to processing equipment. Under § 151.3111, a service on tangible personal property is exempt if the property itself would be exempt if sold — but that exemption does NOT reach repairs to improvements to realty, which are taxable under Rule 3.357. Since most equipment at gas plants and refineries has been incorporated into realty, repairs to it are taxable. The letter's specific example — an amine system pump that's repaired and reinstalled, with labor charged for both — is taxable in full if the pump has been incorporated into realty (as presumed here). A separately stated charge for repair parts, however, is exempt if the underlying equipment itself qualifies for the manufacturing exemption under § 151.318(a).

2. H2S monitors. The company has both personal (hand-held) H2S monitors and fixed monitors located throughout the plant, and asked whether an "environmental exemption" covers their calibration/repair. The Comptroller couldn't fully answer without more facts, but distinguished: personal, hand-held monitors are presumably NOT incorporated into realty, so they're evaluated separately; fixed monitors that DO become part of the realty are treated like any other realty repair (taxable, per point 1). Two potentially relevant exemptions exist: § 151.318(a)(5) exempts TPP necessary/essential to a pollution-control process used in manufacturing, and § 151.318(a)(10) exempts TPP necessary/essential to comply with public-health laws/rules. If the non-realty monitors qualify under either, their repair/calibration labor is also exempt under § 151.3111.

3. New gas-gathering line and compressor-station construction. Applying the century-old Hutchins v. Masterson & Street three-part test (annexation, fitness/adaptation, and — most heavily weighted — intent to permanently annex), underground gas gathering lines are improvements to realty. But NEW construction of a line, or adding footage to an existing line, is new construction (not a repair) — and a lump-sum charge for new construction is not taxable. If the contract is instead separated (materials billed apart from labor), the contractor must collect tax on the separately stated materials charge.

What this means for you

Gas processing plant operators and oil-field contractors

Distinguish repair of existing incorporated-into-realty equipment (taxable, including labor) from new construction (lump-sum nontaxable, separated-contract materials taxable) — these get very different tax treatment even though both involve pipe, fittings, and similar materials. Separately stated repair parts can be exempt if the equipment itself qualifies under the manufacturing exemption, even when the labor to install those parts is taxed as realty repair.

Companies with plant-wide environmental/safety monitoring equipment

Track which monitors are personal/portable versus fixed and incorporated into the plant's structure — that distinction alone can determine whether their repair/calibration is taxable realty-repair labor or potentially exempt pollution-control/public-health equipment under § 151.318(a)(5)/(a)(10).

Accountants and tax professionals

This letter is a good illustration of how the manufacturing exemption (§ 151.318), the realty-services exemption boundary (§ 151.3111/Rule 3.357), and the century-old Hutchins realty test interact across a single facility — three genuinely different legal tests applied to different physical items at the same gas plant.

Common questions

Q: Is repairing gas plant processing equipment taxable in Texas?
A: Usually yes, if the equipment has been incorporated into realty — that repair labor is taxed under Rule 3.357, though separately stated repair parts can be exempt if the equipment itself qualifies under the manufacturing exemption.

Q: Are H2S monitors exempt as pollution-control or safety equipment?
A: It depends: personal/hand-held monitors not incorporated into realty may qualify under the pollution-control (§ 151.318(a)(5)) or public-health-compliance (§ 151.318(a)(10)) exemptions; fixed monitors incorporated into the plant are treated as ordinary realty repairs.

Q: Is building a new gas-gathering line taxable?
A: New construction (not repair) of an underground line is nontaxable if billed lump-sum; a separated contract's materials charge is taxed.

Q: Can another gas company rely on this letter?
A: Only the taxpayer who requested it can use it for detrimental reliance, and the Comptroller specifically noted it lacked enough facts to fully answer the H2S monitor question — a company with different facts should seek its own confirmation.

Original ruling text

October 27, 1999

"**"

Subject: Texas Sales & Usage Tax

Thank you for your recent e-mail. You asked the following questions pertaining
to a gas processing plant.

1. Repairs (labor and/or parts) on any of the processing equipment, Would this
   be taxable or exempt?

Response. Texas Tax Code 151.3111 exempts a service performed on "tangible
personal property" that would be exempt if sold at the time of the performance
of the service. The exemption does not apply to repairs to improvements to
realty. These are taxable services per Rule 3.357. Most equipment at gas
plants and refineries have been incorporated into realty, and the repair is
taxable. A separately stated charge for repair parts are exempt if the
equipment qualifies for exemption per Texas Tax Code 151.318 (a).

You give an example of an amine system pump that is repaired. The company who
repaired the pump reinstalls the pump and charges for labor for the repair and
reinstallation. Presuming that the items are incorporated into realty, the
charge for the repair and reinstallation is taxable and does not qualify for
exemption.

2. H2S Monitors - You have personal H2S monitors and then H2S monitors that
   are located in different areas of the plant. You ask if under the
   environmental exemption would the calibration and repairs of these monitors be
   exempt?

Response. You have not provided enough information to determine the taxability
of these items. I presume that the personal H2S monitors are hand held and are
not incorporated into realty. The other monitors may become a part of the
realty and their repair or calibration is subject to the discussion in response
1.

Texas Tax Code 151.318 (a)(5) provides an exemption for tangible personal
property used or consumed in the actual manufacturing, processing, or
fabrication of tangible personal property for ultimate sale if the use or
consumption of the property is necessary and essential to a pollution control
process.

Texas Tax Code 151.318 (a)(10) provides an exemption for tangible personal
property used or consumed in the actual manufacturing, processing, or
fabrication of tangible personal property for ultimate sale if the use or
consumption of the property is necessary and essential to comply with federal,
state, or local laws or rules that establish requirements related to public
health.

If the monitors that do not become a part of the realty qualify for exemption,
labor to repair or calibrate the monitors will qualify for the exemption in
Texas Tax Code 151.3111 discussed in response 1.

3. New construction on gas gathering lines & compressor stations that are in
   the field and do not fall under the manufacturing exemption, but is new
   construction would any of this be exempt?

Response. The three tests to be used in determining whether a particular
article or structure is an improvement to realty was set out in the case of
Hutchins v. Masterson & Street, 46 Tex. 551(1877) as follows:

(1) Has there been a real or constructive annexation of the article in question
to realty?

(2) Was there a fitness or adaptation of such article to the uses or purposes
of the realty with which it is connected?

(3) Whether or not it was the intention of the party making the annexation that
the chattel in question should become a permanent accession to the freehold?
--this intention being inferable from the nature of the article, the relation
and situation of the parties interested, the policy of the law in respect
thereto, the mode of annexation, and purpose or use for which the annexation is
made.

Underground gathering lines are considered improvements to realty. The new
construction of the line or adding additional feet to the line are considered
new construction. A lump-sum charge for new construction is not taxable. A
separated contractor will collect tax on the separately stated charge for
materials.

and forms) are also available on our web page .
