The Goods and Services Tax Network (GSTN) has introduced a new Excel-based Invoice Management System (IMS) Offline Tool to simplify compliance for taxpayers. This tool allows businesses to download invoice data, take bulk actions such as accept, reject, or mark pending, and upload responses back to the GST portal using JSON files.
Key Features of the IMS Offline Tool
1. Download the tool from GST Portal → Downloads → Offline Tools → IMS Offline Tool.
2. Extract and enable macros in the Excel file.
3. Download IMS data from the portal in JSON format.
4. Import JSON into Excel utility to auto-populate invoice data.
5. Take actions (accept/reject/pending) and validate the sheet.
6. Generate JSON file and upload it back to the GST portal.
The IMS Offline Tool is a welcome step by GSTN to enhance taxpayer convenience and streamline compliance. Businesses dealing with multiple invoices can now save time, reduce errors, and ensure smoother ITC reconciliation.
