How did Texas tax hole-digging equipment mounted on a conventional truck versus a specialized half-cab chassis?

Plain-English summary

The Texas Comptroller classified hole-digging units by their design, even though they performed the same work. Conventional truck cabs and chassis designed to carry people or property on highways were motor vehicles. A hole digger mounted on a one-person half-cab chassis was movable specialized equipment instead.

When a conventional truck was sold with the hole digger attached, motor vehicle tax applied to the full selling price. If the digger was detached and sold separately, limited sales tax applied to the digger and motor vehicle tax applied to the cab and chassis.

Repair treatment also split. Repairs to the hole digger were taxable, but services to the conventional truck cab and chassis were not. The digger was equipment or cargo, not a functional component serving the truck's transportation purpose. Repairs to the specialized half-cab unit were fully taxable.

What this means for you

Equipment dealers and manufacturers

The physical design and the way the unit was sold controlled which tax applied. Similar function did not produce identical classification.

Repair shops

An attached accessory could remain separately taxable for repair purposes. The letter distinguished work on the digger from service to the conventional truck itself.

Accountants and tax professionals

Analyze the vehicle chassis, attachment status at sale, and the component being repaired. The ruling cites separate rules for specialized equipment, accessories, and repair services.

Q: Was every truck-mounted hole digger taxed as a motor vehicle?
A: No. Conventional highway trucks were motor vehicles, but the one-person half-cab unit was movable specialized equipment.

Q: What tax applied when a conventional truck and digger were sold together?
A: Motor vehicle tax applied to the full selling price when the digger was attached at the time of sale.

Q: What if the digger was sold separately?
A: Limited sales tax applied to the detached digger, while motor vehicle tax applied to the truck cab and chassis.

Q: Were repairs taxable?
A: Repairs to the digger were taxable. Services to the conventional truck cab and chassis were not, while repairs to the specialized half-cab unit were fully taxable.

Original ruling text

January 25, 1985

Dear ***:

Thank you for sending the pictures and brochures of the holediggers.

The two brochures and three of the four pictures depict conventional
truck, cabs and chassis with the hold digging equipment mounted on
them. The fourth picture is of a holedigger mounted on a chassis with
a one man cab.

Even though they perform the same functions, their design causes them
to be taxed differently.

The conventional trucks were designed by the motor vehicle manufacturer
to transport persons or property on the highway and they are taxed as motor
vehicles. The other unit with the half cab, we consider moveable specialized
equipment. The enclosed Rule 3.349 explains the taxability of each type of unit.

The holedigger mounted on the motor vehicle is considered an accessory as
described in the enclosed Rule 3.348. When the truck is sold with the holedigger
attached at the time of sale, the full selling price is taxed under the motor
vehicle tax. If the holedigger is unattached and sold separately from the truck,
limited sales tax is due on the holedigger and motor vehicle sales tax is due
on the truck cab and chassis.

When the units need to be repaired, tax will be due on repairs to the holedigger,
but not on services to the truck cab and chassis. The holedigger, although an
attached accessory, is considered equipment or cargo rather than a functional
part of the motor vehicle which assists in the vehicle's primary purpose of
transportation. The holedigger in fact is used only when the vehicle has become
stationary. Even if the holedigger were somehow used to unload other cargo carried
on a trailer, it would not qualify as a component since its use is to unload cargo
carried on some other unit. Enclosed is also Rule 3.290 under which accessories are
categorized as taxable or non-taxable when repaired.

The unit which is considered moveable specialized equipment, and not a motor vehicle,
is totally subject to tax when repaired.

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