Where any service tax has not been levied or paid or has been short-levied or short-paid or erroneously refunded, the Central Excise Officer may, within one year from the relevant date, serve notice on the person chargeable with the service tax which has not been levied or paid or which has been short-levied or short-paid or the person to whom such tax refund has erroneously been made, requiring him to show cause why he should not pay the amount specified in the notice.
