Background – Auto-Populated Liability in GSTR-3B

The GST portal currently offers pre-filled values in GSTR-3B based on the outward supplies reported in GSTR-1/IFF. However, taxpayers have had the flexibility to manually edit those values. This editable nature has led to discrepancies and mismatches between GSTR-1 and GSTR-3B filings.

What’s Changing?

As per the advisory issued by GSTN (Advisory dated Oct 17th, 2024), a phased implementation of “GSTR-3B hard-locking” has been proposed. Whereas it was proposed to be implemented from January 2025, but differed due to various requests that GSTN have been received from the trade seeking time. Now, with a new advisory dated 7th June 2025, this change will be effective from the July 2025 return period onwards. Whereas,

Key Highlights from the Advisory:

• Auto-populated liabilities in GSTR-3B based on GSTR-1/GSTR-1A/IFF will no longer be editable.
• GSTR-1A has been already available to allow taxpayers to correct GSTR-1 before GSTR-3B filing.
• Hard-locking ensures that the liability shown in GSTR-3B matches GSTR-1-based data.
• This change intends to improve return accuracy and reduce mismatches.

GSTR-1A: The Correction Window

To support this shift, the GSTN has already introduced Form GSTR-1A. This form allows taxpayers to amend outward supplies originally declared in GSTR-1 or IFF. If any discrepancies are noticed before filing GSTR-3B, the taxpayer can now correct them through GSTR-1A, effectively making liability adjustments before final submission.

What GSTN Believes vs Reality

According to GSTN, this update will simplify compliance and prevent mismatches. While the intention is good, tax professionals are concerned that hard-locking might increase the burden on filers. Without the ability to edit GSTR-3B, even minor mistakes in GSTR-1 could lead to unwanted complications if not rectified promptly via GSTR-1A. In essence, the pressure now shifts to accurate GSTR-1 filing and timely corrections.
