(1) If a certificate of registration for a motor vehicle is, on issue, liable to duty, the applicant for registration of the motor vehicle must, before the issue of the certificate, pay to the Registrar an amount equal to the duty payable on the certificate.
Maximum penalty: 50 penalty units.
(2) If a motor vehicle:
(a) has been kept in the Territory for a period of less than 12 months; and
(b) has, during that period, been available for hire or lease to the public from a person carrying on the business of hiring or leasing motor vehicles (without provision of a driver) to the public;
the Commissioner may, on application, assess the duty payable on the certificate as a proportion of the duty actually paid that the number of months the vehicle was kept in the Territory during the registration period (counting a part of a month as a whole month) bears to the number of months in the registration period.
