New York Advisory Opinion TSB-A-96(21)S: If a company buys and registers vehicles as dump trucks, uses them as dump trucks, and only later modifies them (removing the dump body, adding a fifth-wheel hookup) and re-registers them as tractors, can it get a refund of the sales tax paid at purchase under the tractor/trailer exemption?

Plain-English summary

R.J. Valente Gravel, Inc. purchased a number of vehicles that it registered with the Department of Motor Vehicles as trucks, and paid sales tax on those purchases. It used the vehicles part of the year as dump trucks, but periodically converted them into tractors by removing the dump body and attaching a fifth-wheel hookup, so the vehicle could pull a semi-trailer. Because DMV rules require registering a vehicle whose use straddles two classes in the more expensive category -- and tractor registration is pricier than truck registration -- Petitioner actually changed the vehicles' registration from trucks to tractors. Petitioner asked whether the vehicles should now be treated as exempt tractors for sales tax purposes, and whether it could get a refund or credit of the sales tax it originally paid.

The Department ruled against Petitioner on both points. Sales tax is a "transaction tax" -- liability is fixed at the moment of the taxable transaction (the original purchase), not by how the vehicle is used or registered later. Tax Law § 1115(a)(26) exempts tractors, trailers, and semi-trailers as defined in the Vehicle and Traffic Law, and the regulations (20 NYCRR § 528.26(b)(1)) define a "tractor" as a motor vehicle designed and used as the power unit in combination with a trailer or semi-trailer, generally without carrying cargo itself. At the time Petitioner bought these vehicles, they were dump trucks -- registered and used to carry cargo -- so they didn't meet the tractor definition at the point of sale. The fact that Petitioner later modified the vehicles and re-registered them as tractors doesn't reach back and change their tax-exempt status at the original purchase. Accordingly, Petitioner wasn't entitled to any refund or credit of the sales tax it originally paid.

What this means for you

Contractors and haulers with convertible vehicles

If you buy a vehicle that's used and registered as a taxable-category vehicle (like a dump truck) and only later modify it into an exempt-category vehicle (like a tractor), don't expect a sales-tax refund on the original purchase -- exemption eligibility is locked in at the time of the taxable sale, based on how the vehicle was actually designed/used/registered at that moment, not any later conversion.

Anyone claiming a vehicle-type sales tax exemption

If you want a vehicle to qualify as an exempt tractor, trailer, or semi-trailer under § 1115(a)(26), make sure it meets that definition -- generally not carrying cargo itself -- from the outset, since a later change in registration or physical configuration won't retroactively unlock the exemption on the original purchase.

Common questions

Q: Does re-registering a vehicle with the DMV automatically change its sales tax treatment?
A: No -- DMV registration classification and sales tax exemption eligibility are separate questions. The DMV's more-expensive-category registration rule doesn't control how the Tax Department classifies the vehicle for sales tax purposes at the time of the original purchase.

Q: Would the outcome differ if the vehicle had been purchased and used exclusively as a tractor from day one?
A: Yes -- the ruling turns entirely on the fact that these vehicles were dump trucks (cargo-carrying) both at purchase and for part of their subsequent use. A vehicle designed and used as a tractor/power-unit from the start, without carrying cargo, would fit the § 1115(a)(26) definition.

Q: Is there any way to get a refund after a vehicle is converted?
A: Not based on this ruling -- the Department squarely held no refund or credit was available for sales tax already paid, because the exemption analysis is tied to the vehicle's status at the original taxable transaction, not later modifications.

ADVISORY OPINION

PETITION NO.S950711A

On July 18, 1995, a Petition for Advisory Opinion was received from R.J. Valente Gravel,
Inc., 8 Jennifer Drive, Wynantskill, New York 12198.
The issues raised by Petitioner, R.J. Valente Gravel, Inc., are:

1. Whether a vehicle which is used as both a truck and a tractor is considered to be a tractor for sales
   tax purposes if it is registered with the Department of Motor Vehicles as a tractor.
2. Whether the Petitioner is entitled to a refund or credit of sales taxes paid on the purchase of the
   vehicle which is registered with the Department of Motor' Vehicles as a tractor.
   Petitioner makes the following submission of facts.
   Petitioner has purchased a number of vehicles which it has registered with the Department
   of Motor Vehicles as trucks. Petitioner paid sales tax to the vendor at the time of purchase. Petitioner
   uses these vehicles part of the year as dump trucks. However, Petitioner periodically uses these
   vehicles as tractors by removing the dump body and attaching a fifth wheel hookup so that the
   vehicles pull a semi-trailer.
   According to Petitioner, the Department of Motor Vehicles requires that, when a vehicle's
   use changes between two classes during a registration period, it should be registered in the more
   expensive category. The one registration suffices for both uses. The tractor registration is more
   expensive than a truck registration. According to Petitioner, therefore, the vehicles described above
   should be registered with the Department of Motor Vehicles as tractors. Petitioner did, in fact,
   change the registration for these vehicles from a truck registration to a tractor registration.
   Section ll15(a) of the Tax Law provides, in pertinent part, as follows:
   Sec. 1115. Exemptions from sales and use taxes.--(3) Receipts from
   the following shall be exempt from the tax on retail sales imposed
   under subdivision (a) of section eleven hundred five and the
   compensating use tax imposed under section eleven hundred ten:
   *

(26) Tractors, trailers or semi-trailers, as such terms are defined in
article one of the vehicle and traffic law, and property installed on
such vehicles for their equipping, maintenance or repair, provided

such vehicle is used in combination where the gross vehicle weight
of such combination exceeds twenty-six thousand pounds.
Section 525.2(a)(2) of the Sales and Use Tax Regulations provides as follows:
(2) The sales tax is a "transaction tax," liability for the tax occurring
at the time of the transaction. Generally speaking, the taxed
transaction is an act resulting in the receipt of consideration for the
transfer of title, or possession or both to property or rendition of
services from one person to another. The time or method of payment
is immaterial, since the tax becomes due at the time of transfer of
property or rendition of service.
Section 528.26(a) (1) of the Sales and Use Tax Regulations provides as follows:
(1) The sale or lease of qualifying vehicles as defined in subdivision
(b) of this section and property installed on such vehicles for the
equipping, maintenance or repair thereof are exempt from the sales
and use tax.
Section 528.26(b) (1) of the Sales and Use Tax Regulations defines tractor as follows:
(1) A tractor is a motor vehicle designed and used as the power unit
in combination with a semi-trailer or trailer, or two such trailers in
tandem. Any such motor vehicle shall not carry cargo except that a
tractor and semi-trailer engaged in the transportation of automobiles
nay transport motor vehicles on part of the power unit. (emphasis
supplied)
Based on the facts presented, the Petitioner purchased the vehicles and registered them as
dump trucks with the Department of Motor Vehicles. Petitioner then operated the vehicles as dump
trucks. The trucks were modified after registration so that the dump body was removed and a fifth
wheel hookup installed. This enabled the modified truck to operate as a tractor to pull a trailer.
Section 1115(a)(26) of the Tax Law provides an exemption for tractors, trailers or semi-trailers, as
these terms are defined in article one of the vehicle and traffic law. Section 525.2(a)(2) of the Sales
and Use Tax Regulations defines the sales tax as a "transaction tax" where liability for the tax occurs
at the time of the transaction. Section 528.26(b)(1) of the Sales and Use Tax Regulations defines a
tractor as a motor vehicle designed and used as a power unit in combination with a semi-trailer or
trailer, or two such trailers in tandem. This definition states that "[a]ny such motor vehicle shall not
carry cargo except that a tractor and semi-trailer engaged in the transportation of automobiles may

transport motor vehicles on part of the power unit." The motor vehicles purchased by Petitioner were
dump trucks at the time of purchase and Petitioner used them as such. They do not qualify for
exemption from the sales and compensating use tax under Section 1115(a)(26) of the Tax Law since
Petitioner used them as dump trucks to transport cargo prior to being converted to a tractor.
Accordingly, Petitioner is not entitled to a refund or credit of sales taxes paid when the motor
vehicles were originally purchased.
