Request a refund if you find that the road tax in the previous state was greater than it is now following the transfer. Before requesting a refund from the new province, you must complete the re-registration process for your vehicle there. To be eligible for a refund, you must present the following documentation. "The chassis number impression," "The NOC for automotive transfer" and "Copies of vehicle insurance policies," all certify that the RC has been successfully transferred from one state to another. Copy of current state road tax invoice; copy of previous state road tax receipt; copies of any other required documentation. Details of the bank statement to which the cheque will be issued should be provided as proof of the new state.
