A. No Clubbing Allowed in Table 5O

4. Practical Impact for Businesses

✔ More Detailed ITC Tracking

Businesses must maintain year-wise ITC ledgers, reversal records, reclaim records, and supporting documentation.

✔ Monthly Reconciliations Now Essential

Avoid waiting until the annual return — mismatches will be difficult to justify later.

✔ Higher Documentation During Audit

GSTR-9C adjustments must be supported with:

• Ledger extract
• Proof of vendor payments
• Cross-year invoices
• E-commerce transaction reports

✔ Vendors Must Be Monitored Closely

Any pending invoices, mismatched GSTR-2B ITC, or missing credit notes will affect annual reporting.

5. What Taxpayers Should Do Before December 2025

• Complete internal reconciliation of GSTR-1, GSTR-3B and books.
• Track all ITC claimed from earlier years separately.
• Confirm whether e-commerce supplies fall under Section 9(5).
• Prepare working papers for GSTR-9C early.
• Clear mismatches visible in GSTR-2B and IMS.
• Avoid last-minute filing — late fee table is now mandatory.

Conclusion

The December 2025 changes to GSTR-9 and GSTR-9C mark a major shift toward more transparent, data-driven and audit-ready GST compliance. With new tables for ITC classification, stricter reconciliation, e-commerce disclosures, and compulsory late fee reporting — taxpayers must prepare in advance.

To avoid penalties, mismatches, or demands, businesses must:

• Maintain accurate records
• Reconcile early
• Track ITC meticulously
• Coordinate with auditors well before the deadline

These updates make GST compliance stronger, but also more work-intensive — so timely preparation is the key.
