The Goods and Services Tax Network (GSTN) has issued a new advisory detailing changes to the Input Management System (IMS), set to take effect on October 1, 2025. These changes will allow taxpayers to keep specific documents, such as credit notes and amendments, pending for one tax period, either monthly or quarterly. This flexibility includes both upward and downward amendments and ECO-documents, provided certain conditions are met. Importantly, if Input Tax Credit (ITC) was not availed for any invoice or document, there will be no need for reversal. However, if ITC was partially availed, reversal is only required for the availed portion.

The updated IMS will also introduce a new facility for taxpayers to declare the actual ITC availed and decide whether to reverse it fully or partially. Another significant update is the option to save remarks when rejecting or keeping a record pending. These remarks will be visible in GSTR-2B and on the supplier dashboard, providing clarity and transparency in communications. These changes are applicable from the October tax period onwards, and the due date for addressing pending records will depend on the supplier's communication date or the relevant tax period. The advisory notes that these updates will apply prospectively to records filed after the changes are implemented.
