4. (1) Notwithstanding anything contained in any other law for the time being in force, where the liability to pay tax in respect of a motor vehicle arises under this Act and such motor vehicle is required to be registered or a new registration mark is required to be assigned to it in the State under the Motor Vehicles Act, 1988, no Registering Authority shall either register any such motor vehicle or assign any new registration mark to such motor vehicle unless payment of such tax has been made by the person concerned in respect of such vehicle.
(2) Where any person causes entry of a motor vehicle into a local area within a period of fifteen months from the date of registration of such vehicle in any Union Territory or any other State under the Motor Vehicles Act, 1988, and that such entry is occasioned as a result of shifting of the place of his residence from such Union Territory or State into this State, the Commissioner may exempt such person from payment of entry tax on entry of such motor vehicle subject to production of proof in this regard."
