GSTR-2B Manual Generation Earlier, GSTR-2B was created automatically. But now, you will have to do it manually by logging into the Invoice Management System (IMS), accepting or rejecting each invoice from your suppliers, and then generating your GSTR-2B. Accepted Invoices for ITC Claim Now, taxpayers can claim the Input Tax Credit (ITC) only for the invoices that they have accepted in IMS. Any rejected invoices will not be included, and the pending invoices will not be shown in your GSTR-3B until you accept them. Changes in Credit Note Taxability If the recipient rejects a credit note in IMS, the supplier's tax liability will not be reduced unless the recipient reverses the ITC that you claimed earlier on that credit note. So both the supplier and the recipient must update their records. The change is only for credit notes issued on or after 1st October 2025, and past credit notes will follow the old rules except for post-sale discounts, where the ITC reversal declaration is still mandatory. GSTR-3B Filing Now Depends on GSTR-2B Now, you cannot file GSTR-3B until your GSTR-2B is generated. For this, you must first accept or reject the invoices in IMS to avoid any delay. No Edit in GSTR-3B Tax Liability From now on, the tax liability shown in GSTR-3B will be autofilled and locked. So, if you want to make any changes, you must do it in GSTR-1 or GSTR-1A.
