How to Cancel a GST Invoice (Credit Note + GSTR-1 Steps)
A GST invoice cannot simply be deleted after it has been issued to a buyer. To cancel or reverse a GST invoice, you must issue a Credit Note — the legally mandated document under Section 34 of the CGST Act. The credit note reverses the original invoice in your GSTR-1 and triggers an ITC reversal for the buyer.

Steps to Cancel a GST Invoice
Step 1 — Issue a Credit Note: Create a Credit Note referencing the original invoice number and date. The credit note must show the original invoice details, the reason for cancellation (goods returned, order cancelled, invoice error), and the full amount being reversed including GST. Step 2 — Report in GSTR-1: Report the credit note in Table 9B of your monthly or quarterly GSTR-1. This reduces your output tax liability for that period. Step 3 — Communicate to Buyer: Inform the buyer that a credit note has been issued. The buyer must reduce their ITC by the GST amount in the credit note. Step 4 — Adjust in GSTR-3B: The net GST effect (output tax reduced by credit note) automatically flows from GSTR-1 to GSTR-3B via the system.
Important
For e-invoices (mandatory above ₹5 crore turnover): An e-invoice can be cancelled on the IRP within 24 hours of generation. After 24 hours, cancellation on IRP is not possible — you must issue a credit note instead.
Time Limit for Credit Note
A credit note must be issued within the earlier of: (a) 30th November following the end of the financial year in which the original supply was made, or (b) the date of filing the annual return (GSTR-9). After this deadline, you cannot reduce your output tax liability via credit note — a huge financial impact. Keep track of cancellation requests and process them quickly, especially as the financial year-end approaches.
Example
A Chennai company issued an invoice for ₹2,00,000 + GST ₹36,000 in June 2026 (FY 2026-27). The buyer returns goods in September 2026. A credit note is issued: CN-2026-001, referencing Invoice No. INV-2026-145, reversing ₹2,00,000 taxable + ₹36,000 GST. The supplier's GSTR-1 for September shows this credit note. The buyer must reverse ₹36,000 ITC in their GSTR-3B for September.
