GST Update: IMS Offline Tool Now Available for Bulk Invoice Actions

The Goods and Services Tax Network (GSTN) has introduced a new Excel-based IMS Offline Tool to simplify invoice management and improve compliance efficiency for taxpayers.

Background: Invoice Management System (IMS)

The Invoice Management System (IMS), introduced from the October 2024 tax period, enables recipient taxpayers to review invoices uploaded by suppliers through GSTR-1, GSTR-1A, or the Invoice Furnishing Facility (IFF). Taxpayers can take actions such as:

• Accept invoices (to claim Input Tax Credit)
• Reject incorrect invoices
• Mark invoices as pending for further review

(As per GSTN framework and advisory dated 21-04-2026)

Introduction of IMS Offline Tool

As per GSTN Advisory dated 21 April 2026, an Excel-based IMS Offline Tool has been made available on the GST portal to enhance taxpayer convenience and ease of compliance.

This tool allows users to:

• Download invoice data from the IMS dashboard
• Work offline using an Excel utility
• Take bulk actions (accept, reject, or pending)
• Upload responses back to the GST portal via JSON files

Key Features of the IMS Offline Tool

1. Bulk Processing of Invoices

Taxpayers handling large volumes of invoices can process them in one go instead of manual, invoice-by-invoice action on the portal.

2. Offline Functionality

The tool reduces dependency on continuous internet access, allowing users to work offline and upload data later.

3. Excel-Based Utility

Built on MS Excel, the tool is user-friendly and familiar for most businesses and professionals.

4. JSON Upload Mechanism

After taking actions, users can generate a JSON file and upload it to the GST portal for seamless integration.

5. In-built Validation Checks

The tool follows the same validations as the online IMS dashboard and highlights errors before upload, enabling correction in advance.

6. Improved ITC Accuracy

By enabling better reconciliation and timely action on invoices, the tool helps improve the accuracy of Input Tax Credit (ITC) claims.

How to Access the Tool

Taxpayers can download the utility from:

• GST Portal → Downloads → Offline Tools → IMS Offline Tool

The tool is provided as a ZIP file and requires extraction and enabling macros before use.

Benefits for Taxpayers

• Reduced manual effort and time consumption
• Better control over invoice reconciliation
• Lower risk of errors in ITC claims
• Enhanced compliance efficiency
• Particularly useful for businesses with high invoice volumes

Conclusion

The introduction of the IMS Offline Tool marks a significant step towards digitized and efficient GST compliance. By enabling bulk processing and offline functionality, GSTN continues to simplify compliance for taxpayers and professionals alike.
