With a view to sensitise stakeholders about the new GST scheme that is to replace a multitude of indirect taxes currently being levied, the Service Tax zone of Kolkata has flagged off a mobile help centre. A network of trained officers will tour the city of Kolkata, conducting seminars, to help stakeholders transition from the Service Tax and Central Excise schemes to the GSTN (GST Network), a front-end system developed by the Government of India as a single interface for the GST roll-out. New registrants will be able to register on-the-spot.
