Does a trackmobile railcar mover lose its Texas rolling-stock sales tax exemption because it has rubber tires and can move under its own power on a highway?

Plain-English summary

The Texas Comptroller ruled that a trackmobile railcar mover — a piece of equipment used to move railcars around a rail yard — qualifies for the rolling stock exemption from sales tax under Tex. Tax Code § 151.331, even though it is equipped with rubber tires and can travel over the highway.

The taxpayer had asked whether adding rubber tires, which let the trackmobile move under its own power from one set of railway tracks to another (including short trips over public roads), would disqualify it from the exemption that applied to a similar piece of equipment the Comptroller's office had already classified as rolling stock back in 1968. The Comptroller concluded it would not: the trackmobile is designed for and used only on railway tracks, and the rubber tires exist solely to let it relocate between track segments, not to serve as a general-purpose road vehicle. Because it can only do the job it was built for — moving railcars on tracks — the ability to travel briefly under its own power to another location does not strip away the exemption.

The ruling has two practical results: (1) a lessor of a trackmobile railcar mover is not required to collect sales tax on the lease, and (2) trackmobile railcar movers are also exempt from motor vehicle sales and use tax.

What this means for you

Railroad and rail-yard equipment lessors

If you lease trackmobile railcar movers (or similar rail-yard equipment that incidentally has rubber tires or limited road capability), this ruling supports treating the lease as exempt rolling stock and not collecting Texas sales tax on it. The key facts the Comptroller relied on were that the equipment is designed and used only on railway tracks, and any highway travel is incidental to relocating between track segments — not a road-transport function.

Businesses buying or leasing railcar movers

Because trackmobile railcar movers are also treated as exempt from motor vehicle sales and use tax, you should not expect to pay sales tax or motor vehicle tax on the purchase or lease of this type of equipment, provided its use matches the facts described here (rail-yard use only, tires used just to shift between tracks).

Accountants and tax professionals

The ruling turns on the "capable of only performing its designed function on railway tracks" test, and cites Hearing No. 21,658 (1988) and a 1968 Comptroller determination on similar equipment as supporting precedent. If your client's equipment has broader highway capability or is used for general road transport, the facts may not match closely enough to rely on this letter.

Common questions

Q: Does having rubber tires automatically disqualify rail equipment from the rolling stock exemption?
A: No. This ruling holds that rubber tires used only to move equipment between sets of railway tracks do not change its status as rolling stock, as long as the equipment is designed for and used only on railway tracks.

Q: Do I have to collect sales tax if I lease out a trackmobile railcar mover?
A: According to this ruling, no — a lessor is not required to collect sales tax on the lease of a trackmobile railcar mover because it qualifies as exempt rolling stock.

Q: Are trackmobile railcar movers subject to motor vehicle sales and use tax?
A: No. The ruling states that trackmobile railcar movers are also exempt from motor vehicle sales and use tax.

Q: Can I rely on this letter for my own equipment?
A: Only if you are the taxpayer to whom it was issued. Letters on Texas's STAR system can be the basis of a detrimental reliance claim only for the original recipient, and this letter may not reflect current Comptroller policy. Consult a Texas tax professional to confirm your specific equipment and facts qualify.

Original ruling text

August 31, 1992

Dear ***:

On August 25, 1992, you wrote concerning the taxability of a trackmobile
railcar mover. The question is whether the trackmobile railcar mover is
classified as rolling stock in accordance with sec. 151.331, Tex. Tax Code. I
have concluded that the trackmobile railcar mover is rolling stock for purposes
of the sales tax exemption. Therefore, a lessor is not required to collect
sales tax on the lease of a trackmobile railcar mover.

As you pointed out, in 1968 this office concluded a similar piece of equipment
was rolling stock and exempt. The fact that the trackmobile railcar mover is
capable of moving over the highway does not change its status. The trackmobile
is designed for and used only on railway tracks. It is equipped only with
rubber tires to allow it to move from one set of tracks to another. Because it
can only perform the function for which it was designed when operated on
railway tracks, I conclude it does not lose its exemption because it can move
under its own power to another location. See Hearing No. 21,658 (1988).

Also, trackmobile railcar movers are exempt from the motor vehicle sales and
use tax.

I hope this satisfactorily answers your inquiry. Should you need further
clarification, please feel free to contact me.

Sincerely,

Wade Anderson
Assistant Director of Tax Administration
