Mandatory Change: Table 3.2 of GSTR-3B is Now Non-Editable
Advisory on Filing GSTR-3B with Auto-Populated Inter-State Supply Values (Dec 5th, 2025).
This advisory from the GST Network announces a critical change to the filing procedure of Form GSTR-3B. To enhance data consistency and compliance, the values declared in Table 3.2—which captures inter-state supplies—will now be mandatory and non-editable, starting from the November 2025 tax period onwards.
What is Captured in Table 3.2 of GSTR-3B?
Table 3.2 of Form GSTR-3B captures the inter-state supplies made to three specific categories of recipients, taken out of the total supplies declared in Table 3.1 & 3.1.1 of GSTR-3B:
- Unregistered persons.
- Composition taxpayers.
- UIN (Unique Identification Number) holders.
This data is auto-populated from corresponding supplies declared in GSTR-1, GSTR-1A, and IFF (Invoice Furnishing Facility) in the requisite tables.
The New Filing Procedure: Non-Editable Values
Starting from the November 2025 tax period onwards, the core change is as follows:
Mandatory Filing Requirement:
The value of supplies auto-populated in Table 3.2 of GSTR-3B from the returns/forms mentioned above, shall be made non-editable. The GSTR-3B shall be filed henceforth with the system generated auto-populated values only in table 3.2.
How to Modify/Amend Auto-Populated Values
If you identify an error and need to correct the auto-populated value in Table 3.2, the modification must be made in the source forms:
- For Instant Amendment: Any modification/amendment required in the auto-populated values of Table 3.2 of GSTR-3B can be done through GSTR-1A for the same tax period. The values thus reported in GSTR-1A shall change the auto-populated values of table 3.2 in GSTR-3B instantly, allowing you to file GSTR-3B with the updated values.
- For Future Amendment: The amendment of such supplies can always be reported in Form GSTR-1/IFF filed for subsequent tax periods.
Key Takeaway 💡
This change mandates accuracy in the initial filing of GSTR-1/IFF for all inter-state supplies, as manual correction in GSTR-3B's Table 3.2 is no longer possible. To ensure GSTR-3B is filed accurately with no hassle, it is advised to report the correct values in GSTR-1, GSTR-1A, or IFF. This enforces a direct link between the outward supply reporting forms and the liability summary, ensuring compliance with GST regulations.
