(a) The department shall withhold the registration or the transfer of registration of any vehicle sold at retail to any applicant by any person other than a vehicle manufacturer or dealer holding a license and certificate issued pursuant to Chapter 4 (commencing with Section 11700) of Division 5, or an automobile dismantler holding a license and certificate issued pursuant to Chapter 3 (commencing with Section 11500) of Division 5, or a lessor-retailer holding a license issued pursuant to Chapter 3.5 (commencing with Section 11600) of Division 5, and subject to the provisions of Section 11615.5, until the applicant pays to the department the use tax measured by the sales price of the vehicle as required by the Sales and Use Tax Law (Part 1 (commencing with Section 6001) of Division 2 of the Revenue and Taxation Code), together with penalty, if any, unless the State Board of Equalization finds that no use tax is due. If the applicant so desires, he may pay the use tax and penalty, if any, to the department so as to secure immediate action upon his application for registration or transfer of registration, and thereafter he may apply through the Department of Motor Vehicles to the State Board of Equalization under the provisions of the Sales and Use Tax Law for a refund of the amount so paid. (b) The department shall transmit to the State Board of Equalization all collections of use tax and penalty made under this section. This transmittal shall be made at least monthly, accompanied by a schedule in such form as the department and board may prescribe. (c) The State Board of Equalization shall reimburse the department for its costs incurred in carrying out the provisions of this section. Such reimbursement shall be effected under agreement between the agencies, approved by the Department of Finance. (d) In computing any use tax or penalty thereon under the provisions of this section, dollar fractions shall be disregarded in the manner specified in Section 9559 of this code. Payment of tax and penalty on this basis shall be deemed full compliance with the requirements of the Sales and Use Tax Law insofar as they are applicable to the use of vehicles to which this section relates.
