Locking of GSTR-3B

The government has come up with hard locking of GSTR-3B. The auto-filled liability in GSTR-3B cannot be edited by the taxpayer from July 2025. This initiative aims to bring transparency to the GST return filing process and prevent taxpayers from evading taxes. Earlier, taxpayers could manually edit the tax liability auto-filled in GSTR-3B. However, starting from July 2025, the taxpayers cannot edit the auto-filled liability in GSTR-3B.

If a taxpayer wants to make any corrections, then the same can only be done through GSTR-1A before filing GSTR-3B. Only the reverse charge can be entered manually by the taxpayers.

3-Year Time Limit

Starting from July 1, the GST portal will not accept any filing that is more than 3 years overdue. It will block such a filing return. GST returns (including GSTR-1, GSTR-3B, GSTR-4, GSTR-5, GSTR-5A, GSTR-6, GSTR-7, GSTR-8, GSTR-9) are not allowed after 3 years from the due date. The due date for filing all returns older than 3 years was June 30, 2025. Now from July 2025, taxpayers cannot file such return filing.

Input Tax Credit

The values of GSTR-2B and GSTR-3B are required to match for a correct ITC claim. Any discrepancies between the two can result in an incorrect ITC claim, resulting in penalties and interest. Taxpayers must know that now starting from July 2025, any errors in GSTR-1 will affect GSTR-2B and GSTR-3B ITC detail. Therefore, make sure there are no mistakes in GSTR-1.

The due date to claim the ITC remains 30 November of the relevant financial year.
