GST Return Mistake? A New Correction Process Is Open for Feedback

Updated: 2 November 2026 · Tax Filing Guru Editorial Team

You file GSTR-1, check the ITC in GSTR-2B and complete GSTR-3B. Then a difference appears between the figures. Correcting the number in GSTR-3B alone may leave the underlying record unchanged, and the mismatch can lead to an intimation or notice. The government is asking whether a different correction process would work better.

CBIC has opened a public consultation on an alternate mechanism for amending liability and input tax credit (ITC) in GST returns. The feedback window runs from 1 to 30 November 2026. This is a proposal; it is not a new portal option you can use today.

Why is CBIC proposing a change?

The government's consultation note says two common differences cause trouble: tax liability reported in GSTR-1 versus tax paid in GSTR-3B, and ITC available in GSTR-2B versus ITC claimed in GSTR-3B. Taxpayers can currently edit certain auto-populated figures before filing GSTR-3B, but direct edits may leave the source statements out of step.

The proposal aims to make corrections closer to those source records, so the return figures reconcile more reliably and fewer avoidable notices or system intimations arise. Whether the eventual mechanism achieves that will depend on its final rules and portal design.

Three changes worth watching

1. More detail in GSTR-1 and GSTR-1A: The note proposes clearer identification of the underlying supply type for credit notes, advances and similar records, helping amounts flow to the right GSTR-3B table.
2. Wider use of GSTR-1A for corrections: It proposes allowing certain earlier-period details and a recipient GSTIN to be corrected through GSTR-1A where currently restricted.
3. Corrections at the source: For certain earlier-period outward-supply liabilities, the proposal points to amendment tables in GSTR-1 or GSTR-1A instead of directly altering an auto-populated GSTR-3B figure. It discusses reverse-charge liability separately.

The 93-page note also covers other situations, including tax already paid through DRC-03, reverse-charge reporting, ITC statements and draft changes to forms. A business should review the part relevant to its own transactions rather than assuming one proposed workflow applies to every error.

What should you do now?

Keep using the GST rules and portal facilities currently in force. Reconcile invoice-level GSTR-1 records with GSTR-3B liability and compare GSTR-2B with the ITC claimed. Where you find a difference, preserve the invoice, return, ledger and correspondence that explain it, and use the currently permitted correction route for your facts.

If your business has repeatedly faced mismatches, this is a chance to describe a specific problem to policymakers. The MyGov consultation page accepts suggestions until 30 November 2026. Read the note first, explain which form or step causes the issue, give a practical example without unnecessary private data, and suggest how the process could be clearer. The page says participation is voluntary and submission does not guarantee a policy change.

Takeaway: The proposal addresses a real filing pain point, but it has no immediate effect on how you correct a return today. If you need help reviewing an existing GSTR-1, GSTR-2B and GSTR-3B mismatch, contact Tax Filing Guru with the relevant return periods and records.
