TX 8405L0576A01 Motor Vehicle Tax 1984-05-23

Did Texas apply motor vehicle tax or limited sales tax to concrete pumping trucks, trailers, pumps, and booms?

Short answer: A truck with a concrete pump attached was subject to motor vehicle tax. A trailer built specifically to pump concrete and not mounted on a motor vehicle was movable specialized equipment subject to limited sales tax. If the truck, pump, and boom were bought separately, each followed its own tax at purchase; once sold together with the equipment attached, motor vehicle tax applied to the entire unit.

About this page: The plain-English summary, reader guidance, and Q&A below were written by Ezel based on the official state tax ruling. The original ruling (linked on this page) is the authoritative source for any reliance.

Plain-English summary

A concrete pump mounted on a truck followed motor vehicle tax, while a purpose-built pump trailer not mounted on a motor vehicle followed limited sales tax as movable specialized equipment.

When a taxpayer bought the truck from one vendor and the pump and boom from another, motor vehicle tax applied to the truck and limited sales tax applied to the pump and boom.

When the taxpayer later sold the truck with the pump attached, the attached equipment became accessories in the sale and motor vehicle tax applied to the entire unit.

What this means for you

Tax classification changed with the platform and transaction stage. Separately acquired specialized equipment could initially follow sales tax but later enter the motor vehicle tax base when attached and sold with the truck.

Common questions

Q: Was a pump truck movable specialized equipment?
A: No; the letter applied motor vehicle tax.

Q: What about a purpose-built pump trailer?
A: Limited sales tax applied.

Q: What happened when truck and pump were sold together?
A: Motor vehicle tax applied to the entire attached unit.

From: Tom Gay, Tax Policy Section

Subject: Concrete Pumping Trucks and Trailers

I've attached Motor Vehicle Sales and Use Tax Rules 3.87 and 3.88,
excerpts from our County Tax Assessor-Collector Guidebook, and Brochure
96-106. Brochure 96-169 is also helpful, however we are currently out.

As you can see trucks (motor vehicles) with concrete pumps attached are
subject to Motor Vehicle Tax.

It appears the concrete pump trailers are designed and built
specifically to pump concrete and are not mounted on a motor vehicle.
Therefore, they would be moveable specialized equipment and taxed by
Limited Sales Tax.

If your taxpayer purchases a truck from one vendor and the concrete pump
and boom is purchased from another vendor, Motor Vehicle Tax is due on
the truck and Limited Sales Tax is due on the pump and boom.

When the Taxpayer sells the truck and pump. Vehicle Tax is due on
the entire unit since the "accessories" are attached at the time of sale.

If you need more information, please write or call.

Thanks,

Tom Gay
