Starting from the April 2025 tax period, the GST Network (GSTN) has made a critical compliance update: Table 3.2 of Form GSTR-3B is now non-editable. This table, which reflects inter-state supplies to unregistered persons, composition taxpayers, and UIN holders, will be auto-populated directly from GSTR-1/IFF data and can no longer be modified manually.

This move aims to align reporting across GSTR-1 and GSTR-3B and eliminate discrepancies.

GSTR-3B Auto-Population Update: Key Changes from April 2025

🔍 What is Table 3.2 in GSTR-3B?

Table 3.2 captures:

  • Inter-state outward supplies to unregistered buyers
  • Supplies to composition dealers
  • Supplies to UIN holders (e.g., embassies)

These are derived from values entered in Table 3.1/3.1.1 of GSTR-3B, which in turn come from GSTR-1, GSTR-1A, and IFF.


🚨 What’s Changing Now?

Taxpayers could manually edit 3.2Editing disabled – auto-populated by GSTN only
Inconsistencies often overlookedAccuracy of GSTR-1/IFF becomes critical
Corrections allowed in 3B directlyOnly via GSTR-1A/IFF amendments in later months

🧾 Why This Matters

  • No manual corrections in GSTR-3B from now.
  • Mismatch risk: Wrong entries in GSTR-1/IFF can’t be fixed at 3B stage.
  • Time-sensitive rectification: Corrections allowed only via GSTR-1A in subsequent periods.
  • Higher scrutiny on inter-state B2C disclosures.

✅ What Should Taxpayers Do?

To comply effectively with GSTR-3B auto-population:

  • Double-check all inter-state B2C supplies in GSTR-1 before filing.
  • Cross-verify data between GSTR-1, IFF, and ERP systems.
  • Use GSTR-1A immediately if any amendment is required.
  • Train staff handling filings to adapt to this no-edit regime.

📌 Expert Insight

“This is not just a tech update – it’s a compliance culture shift. The system now assumes your GSTR-1 is gospel. A single error can carry forward and mess up your 3B and credit trail,” says a leading GST practitioner.


❓FAQs

Q1. What if wrong value appears in Table 3.2?
👉 You must amend it through GSTR-1A or next period’s GSTR-1. No edit allowed in GSTR-3B.

👉 No, this applies only to inter-state supplies to unregistered persons, composition dealers, and UIN holders.

Q3. Can I ignore Table 3.2 if I’ve disclosed everything in GSTR-1?
👉 No. Even though it’s auto-filled, incorrect values may affect credit distribution and return validation.


📣 Final Takeaway

The new GSTR-3B auto-population rule is a reminder: GSTR-1 is now your source of truth. Any mistake here will ripple across your compliance chain. Keep filings tight, timely, and tested.
