The Tax Code (Section 152.003) authorizes the Comptroller to supervise the collection of motor vehicle sales taxes (MVSTs) and to make rules for determining the taxable value of motor vehicles. Purchasers pay taxes on motor vehicle sales to their local county tax assessor-collectors, generally through automobile dealers.
The Tax Code (Chapter 152 Subchapter F) also sets forth MVST violations; two of the offenses are felonies punishable by fines and/or imprisonment:
Convictions may result in the suspension or revocation of a motor vehicle retail seller's permit (Tax Code Section 152.068). Once a permit has been revoked, the Comptroller's office may not issue a new permit unless satisfied that the former permit holder will comply with motor vehicle sales tax laws and applicable Comptroller rules.
Motor vehicle sales tax crimes are prosecuted in the counties in which they occur.
