Advisory on Hard-Locking of Auto-Populated Values in GSTR-3B

Date: October 17, 2024


Subject: Upcoming Restriction on Modifying Auto-Populated Values in GSTR-3B from January 2025 Tax Period

Dear Taxpayers,

In its ongoing efforts to streamline the return filing process and minimize errors, the Goods and Services Tax Network (GSTN) has introduced several improvements. One of the key enhancements is the provision of a pre-filled GSTR-3B form, which auto-populates tax liabilities and Input Tax Credit (ITC) based on data from GSTR-1/GSTR-1A/IFF and GSTR-2B.





Key Features of the Pre-Filled GSTR-3B:

  1. Auto-Population of Tax Liability:
    • Tax liability is auto-populated from the supplies declared in GSTR-1, GSTR-1A, or the Invoice Furnishing Facility (IFF).
  2. Auto-Population of ITC:
    • The Input Tax Credit (ITC) values are auto-populated based on the details available in GSTR-2B, giving taxpayers an accurate summary of the ITC they are entitled to claim.
  3. System-Generated PDF:
    • Taxpayers can access a detailed PDF of the auto-populated GSTR-3B, providing them with a clear view of the return data before submission.

Amendment and Correction Mechanisms:

To ensure accuracy in filing, taxpayers have access to tools that allow them to correct any discrepancies in their returns:

  1. Amendment via GSTR-1A:
    • Taxpayers can amend incorrectly declared outward supplies in GSTR-1/IFF through GSTR-1A. This enables corrections before filing GSTR-3B, ensuring that the tax liability in GSTR-3B matches the correct figures.
  2. Invoice Management System (IMS) for ITC Claims:
    • To manage inward supplies and ensure correct ITC claims, taxpayers can use the Invoice Management System (IMS) to take actions such as accepting, rejecting, or marking invoices as pending. This feature helps ensure accurate reporting of inward supplies and corresponding ITC in GSTR-3B.

Upcoming Changes: Hard-Locking of Auto-Populated Values in GSTR-3B

To further improve accuracy and reduce manual errors, starting from the January 2025 tax period, the GST Portal will implement hard-locking of auto-populated values in the pre-filled GSTR-3B form. This means that taxpayers will no longer be able to manually modify the auto-populated values derived from GSTR-1/GSTR-1A/IFF and GSTR-2B.

Important Notes:

  • Amendments to outward supplies must be done via GSTR-1A before the GSTR-3B filing.
  • For inward supplies, corrections should be managed through the Invoice Management System (IMS).

Taxpayers are strongly encouraged to review their returns and correct any discrepancies before the GSTR-3B filing using these amendment and correction tools.


Action Items for Taxpayers:

  1. Verify Auto-Populated Data:
    • Ensure that the data auto-populated in GSTR-3B from GSTR-1/IFF and GSTR-2B is accurate.
  2. Use GSTR-1A for Corrections:
    • Any changes required in the declared outward supplies must be made through GSTR-1A.
  3. Leverage IMS for ITC Management:
    • Use the Invoice Management System (IMS) to manage inward supplies and ensure accurate ITC claims.

Effective Date:
This restriction on editing auto-populated values in GSTR-3B will begin with the January 2025 tax period.

Taxpayers are advised to familiarize themselves with the process of correcting data through GSTR-1A and IMS to ensure smooth and accurate filing going forward.

For any questions or further assistance, please contact the GST Helpdesk.


Thanking You,
Team GSTN


This advisory informs taxpayers about the upcoming hard-locking of auto-populated values in GSTR-3B, effective January 2025, and provides guidance on how to handle discrepancies through the available amendment tools.
