Are forming lumber, paper cups, rental equipment repairs, and fuel for rented equipment taxable or exempt under Texas sales and use tax?

Plain-English summary

This 1992 letter answers seven separate taxability questions submitted by a construction-industry taxpayer, most involving job-site materials and rented equipment.

On forming lumber -- the boards used to build concrete forms at a construction site -- the Comptroller agreed with the taxpayer's own analysis: if the lumber is discarded after use (not permanently incorporated into the building), it is a taxable consumable item. But if the lumber is reusable, it is instead classified as equipment rather than a one-time consumable. Paper cups purchased for employee drinking water were confirmed taxable as consumables not incorporated into realty, and repair of rental equipment was confirmed taxable.

The largest portion of the letter addresses when fuel charges for rented equipment are taxable. The rule turns on two things: whether the lessor supplies an operator, and how the charges are billed. Fuel for "bare" equipment rental (no operator, no taxable service provided by the lessor) is not taxable. When the lessor provides both equipment and an operator but bills the operator's charge separately, the fuel is taxable as part of the equipment rental tax base -- because it's a necessary expense of operating the equipment -- even if the fuel itself is separately stated. But if equipment and operator are billed together as a single, undifferentiated charge, that combined charge is presumed to be for a service, and any separately stated fuel charge within it is not taxable. Fuel is taxable outright when the lessor is providing an operator and also providing a taxable service.

Finally, the letter confirms that labor and profit on new construction are not taxable -- consistent with Texas's general rule that new construction labor is not a taxable service.

What this means for you

Contractors and construction companies

Track whether your forming lumber, plywood, and similar job-site materials are single-use (discarded after the pour) or reused across multiple jobs. Discarded forming materials are taxable consumables; reusable forming materials are treated as equipment instead. Also remember that labor and profit on new construction remain untaxed, distinct from the taxability of the materials and supplies consumed on the job.

Businesses that rent equipment with or without an operator

How you structure your rental invoice affects the tax result on fuel. A single combined charge for equipment plus operator (with no separate fuel line) is treated as a nontaxable service charge for fuel purposes. But if you separately state the operator's charge, any fuel charge becomes taxable as part of the equipment rental base, even if fuel is broken out on its own line.

Accountants and tax professionals

This letter is a useful short reference on the "bare equipment vs. equipment-with-operator" distinction and how billing structure (separately stated vs. lump-sum) changes the taxability of ancillary charges like fuel and repairs. Note it addresses seven separate, only loosely related fact patterns in a single letter -- each item should be read independently rather than as one integrated holding.

Common questions

Q: Is forming lumber used to build concrete formations always taxable?
A: Not always. It's taxable as a consumable if it's discarded after use. If the lumber is reusable, the Comptroller says it is classified as equipment instead, which is treated differently.

Q: If I rent equipment with an operator, is the fuel taxable?
A: It depends on billing. If the operator's charge is separately stated from the equipment charge, fuel is taxable as part of the equipment rental tax base. If equipment and operator are billed as one combined charge, that charge is presumed to be a nontaxable service, and a separately stated fuel charge within it is not taxable.

Q: Is fuel taxable for bare equipment rental with no operator?
A: No. If the lessor does not provide a taxable service and does not provide an operator, fuel for that bare equipment rental is not taxable.

Q: Are paper cups bought for employee drinking water taxable?
A: Yes. The letter confirms they are consumable items not incorporated into realty, and are taxable.

Original ruling text

May 19, 1992

Dear ***:

Thank you for your recent letter asking about the taxability of the following
items.

1. Forming lumber used on the job site to construct concrete formations and
   then discarded is considered a consumable item, not permanently incorporated
   into the realty, and is taxable.

Response: Correct, if as you indicate, the lumber is discarded. If the lumber
is reusable, the lumber would be classified as equipment.

2. Paper cups purchased for drinking water for employees are consumable items,
   not incorporated into the realty, and are taxable.

Response: Correct.

3. Repair of rental equipment is considered taxable.

Response: Correct.

4. The fuel for bare equipment rental wherein the Lessor does not provide a
   taxable service and does not provide an operator is not taxable.

Response: Correct.

5. Fuel for equipment rental wherein the Lessor does not provide a taxable
   service but does provide an operator is taxable.

Response: Correct, if the charge for equipment is separately stated from the
charge for the operator. When a person is not providing a taxable service, but
provides equipment and an operator, with the charge for the operator separately
stated, the fuel is a necessary expense the operator incurred while operating
the equipment and is part of the tax base for the equipment rental even though
the charge for fuel is also separately stated.

A separately stated charge for fuel is not taxable when a person, who is not
providing a taxable service, provides equipment and operator for a single
charge. Equipment and operator for a single charge is presumed to be for a
service.

6. Fuel for equipment rental wherein the Lessor is providing a taxable service
   and an operator is taxable.

Response: Correct.

7. Labor on new construction and profit on labor for new construction is not
   taxable.

Response: Correct.

This opinion is based on the facts presented. If there are additional or
different facts, the opinion may change.
