Quick Answer
The GSTR-9C Offline Utility is an official tool provided on the GST portal that helps taxpayers prepare and upload their annual reconciliation statement in an offline environment. Users can download the utility, enter reconciliation details, validate the information, generate a JSON file, and upload it to the GST portal. The offline utility reduces data entry errors, simplifies large reconciliations, and makes GSTR-9C filing more efficient.
Every registered taxpayer required to file an annual reconciliation statement must ensure that the information reported in GST returns matches the books of accounts. This reconciliation process is performed using Form GSTR-9C, which helps identify differences between financial records and GST returns filed during the financial year.
To make this process easier, the GST portal provides the GSTR-9C Offline Utility. Instead of entering large amounts of data directly on the portal, taxpayers can prepare their reconciliation statement offline, validate the information, generate a JSON file, and upload it securely.
This guide explains everything you need to know about the GSTR-9C offline utility, including how to download it, install it, prepare the reconciliation statement, generate JSON files, and file your annual reconciliation return correctly in 2026.
