How to Use IMS Offline Tool in GST – Step-by-Step Guide
The Goods and Services Tax Network (GSTN) has issued an advisory on the IMS Offline Tool available on the GST portal to enhance taxpayer convenience and streamline compliance.
The Invoice Management System (IMS) has been introduced on the GST portal with effect from the October 2024 tax period. This system allows recipient taxpayers to take actions on invoices uploaded by their suppliers through GSTR-1, GSTR-1A, or Invoice Furnishing Facility (IFF).
Taxpayers can now accept, reject, or keep invoices pending, thereby improving accuracy in input tax credit (ITC) claims and overall compliance.
To further enhance convenience and ease of compliance, an Excel-based IMS Offline Tool has now been made available on the GST portal. This utility allows taxpayers to manage both individual and bulk invoice actions efficiently in an offline environment.
