The Goods and Services Tax Network (GSTN) has introduced an Excel-based IMS Offline Tool on the GST portal to simplify invoice management and improve efficiency for taxpayers dealing with large volumes of invoices.

📌 Background: Invoice Management System (IMS)

The Invoice Management System (IMS) was introduced on the GST portal to enable recipients to take actions on inward supply invoices reflected in their records.

Through IMS, taxpayers can:

• Accept invoices for Input Tax Credit (ITC)

• Reject incorrect invoices

• Mark invoices as pending for further review

These actions directly impact ITC availability in GSTR-2B and subsequent GST returns.
