New Advisory for IMS Offline Tool on GST Portal: Complete Guide for Taxpayers

The GST ecosystem in India continues to evolve with regular updates aimed at improving compliance and efficiency. One such important update has been introduced by GSTN regarding the Invoice Management System (IMS), along with a newly launched IMS Offline Tool. This advisory directly impacts how businesses manage supplier invoices, debit notes, and credit notes.

If you are involved in GST Return Filing Ahmedabad or using a GST Registration Service, understanding this update is essential to ensure accurate Input Tax Credit (ITC) and avoid mismatches.

What is the Invoice Management System (IMS)?

The Invoice Management System (IMS) is a functionality on the GST portal that allows taxpayers to take action on invoices uploaded by their suppliers through GSTR-1, GSTR-1A, or IFF.

With IMS, you can:

• Accept invoices
• Reject invoices
• Keep invoices pending
• Take no action

This system has been applicable from the October 2024 tax period, making it a crucial part of GST compliance.

IMS plays a key role in ensuring that only valid invoices are considered for ITC claims, helping businesses maintain clean and accurate records.

Introduction to the IMS Offline Tool

To further simplify invoice management, GSTN has now introduced an Excel-based IMS Offline Tool. This tool is especially beneficial for businesses dealing with a large volume of invoices.

Instead of taking action on invoices one by one on the portal, the offline tool allows bulk processing in a structured and efficient way.

Key Features of IMS Offline Tool:

• Download supplier invoices in JSON format
• Import data into the Excel utility
• Take bulk actions (Accept / Reject / Pending)
• Validate invoice data
• Generate a JSON file for upload
• Upload updated data back to the GST portal

This tool makes the entire process faster, reduces manual effort, and minimizes the chances of errors.

Step-by-Step Process to Use the IMS Offline Tool

To help you get started, here is a simple step-by-step guide:

Step 1: Download the Tool

• Visit the GST portal: www.gst.gov.in 
• Go to Downloads → Offline Tools → IMS Offline Tool
• Download and extract the ZIP file
• Enable macros in the Excel file

Step 2: Download IMS Data from Portal

• Log in to the GST portal
• Navigate to Services → Returns → IMS Dashboard → Offline
• Click on “Generate JSON File to Download”
• Save the JSON file to your system

Step 3: Import JSON into Offline Tool

• Open the Excel utility
• Click on “Open Downloaded IMS JSON File”
• All invoice data will be auto-populated

Now, you can:

• Accept, Reject, or Keep Pending invoices
• Add remarks if required
• Click on “Validate Sheet” to check for errors

Step 4: Generate JSON and Upload

• Click on “Generate JSON File to Upload”
• Go back to GST portal → IMS Dashboard → Offline
• Upload the generated JSON file

If any issues arise, the portal will generate an error file, which can be corrected using the same tool.

Important Points to Remember

While using the IMS Offline Tool, keep these important points in mind:

• The tool follows the same validations as the online IMS dashboard
• If no changes are made, the generated JSON file will be empty
• Filters used in Excel may reset during validation
• Error reports will be generated for incorrect data
• Uploaded records are incremental and may overwrite earlier entries for the same GSTIN

Being aware of these points will help you avoid common mistakes and ensure smooth processing.

Why This Update Matters for Your Business?

The introduction of the IMS Offline Tool is a significant step toward simplifying GST compliance, especially for businesses handling bulk transactions.

Key Benefits:
