TaxTMI 
Three GST notices. Same issue. Same assessment period. Two different cities chasing one taxpayer for the same transaction. If this sounds familiar, you are not alone.
This is exactly what happened to a business dealing with Input Service Distributor (ISD) credit from Karnataka to Chennai. Chennai authorities initiated proceedings. Bangalore authorities did the same. The taxpayer was stuck fighting parallel battles for one transaction.
Understanding the Problem of Duplicate GST Notices
Parallel proceedings are not just inconvenient. They are illegal under Indian GST law. When two tax offices investigate the same matter simultaneously, it wastes everyone's time. More importantly, it violates the law designed to prevent such duplication.
The CGST Act has a clear provision for this. Section 6(2)(b) states that once one proper officer has initiated any proceedings on a subject matter, no other officer can start proceedings on the same subject. The law exists precisely to protect taxpayers from being harassed by multiple authorities.
The Legal Solution That Worked
In the case mentioned above, the approach was straightforward. The taxpayer informed the Bangalore authorities that Chennai had already passed two orders on the same subject and time period. The matter was backed by a recent Supreme Court judgment in M/s ARMOUR SECURITY (INDIA) LTD. Versus COMMISSIONER, CGST, DELHI EAST COMMISSIONERATE & ANR. - 2025 (8) TMI 991 - Supreme Court.
The Supreme Court's guideline was clear. Tax authorities must coordinate with each other to avoid duplication. They cannot independently pursue the same taxpayer for identical issues.
Bangalore reviewed the submission. They applied the law correctly. The proceedings were dropped without drama or endless hearings.
Key Takeaways for Taxpayers Facing Duplicate Notices
When you receive multiple GST notices for the same issue, do not panic or try fighting on multiple fronts. First, check if the notices cover the same subject matter and assessment period. Second, identify which authority initiated proceedings first. Third, invoke Section 6(2)(b) before the second authority and provide proof of existing proceedings.
Keep documentation ready. This includes copies of earlier notices, orders, and acknowledgements showing the timeline of proceedings. The authority that started later must step back under the law.
Conclusion
GST compliance should not mean bleeding time and resources across multiple cities. The law protects you from duplicate proceedings. Use Section 6(2)(b) of the CGST Act when needed. Make one office step back so you can focus on resolving the actual issue.
