GST Network will launch the Invoice Management System (IMS) from October 1 which will facilitate taxpayers in matching their records/invoices vis-a-vis issued by their suppliers for availing the correct Input Tax Credit (ITC). In an advisory to Goods and Services Tax (GST) payers, GSTN said to enable taxpayers to efficiently address invoice corrections/amendments with their suppliers through the portal, a new communication process called the IMS is being launched. "This will also facilitate taxpayer in matching of their records/ invoices vis-a-vis issued by their suppliers for availing the correct ITC," GSTN said.
