India's tax system doesn't sleep anymore. Every GSTIN is a live data node. Every mismatch is flagged before you file. The infrastructure most enterprise finance teams inherited was built for a different era, and the gap is now measurable.

One Insight from the Research
The leading cause of enterprise GST notices is not your vendors.
It is not the complexity of rate structures. It is not an ambiguous law.
It is an internal data hygiene problem.
The GSTR-1 and the GSTR-3B are being filed from different data sets. Same invoices. Same transactions. Two different numbers. One automatic mismatch notice from the GSTN.
80%
of enterprises in the study received at least one notice in FY 2025 traced to this exact cause. The breakdown by industry, by notice type, and by the systems quietly causing it, is inside the report.

GSTN auto-flags the mismatch, demand notice generated

Voices From Inside the Report
The finance leader. And the regulator.
For the first time in an enterprise CFO report, both sides of the return, on the record.

The Voice of the Finance Leader
Sunil Kumar has spent almost a decade running finance inside one of India's most operationally complex retail enterprises. Multi-state. Multi-category. Thousands of transactions every day. His take on what broke, what got fixed, and what every CFO still gets wrong about GST compliance, in his own words.
"It is no longer 'are we filing on time?' It is 'is the data we are filing actually right?' That shift sounds small. It is not."
- Sunil Kumar, General Manager - Finance, Joyalukkas
Inside the report, Sunil unpacks:
Why the real cost of getting ITC right is a number most finance leaders haven't put on a slide yet
The audit tail: Why rate reinterpretations arriving three to five years after filing are the single biggest unmodelled risk on an enterprise balance sheet
The only real defence at the point of filing, and what it actually takes to build it
The one technology that has genuinely moved the needle (and what it hasn't solved)
For the first time in an enterprise CFO report, the view from the other side of the return. Dr. Kotraswamy M., IRS, Commissioner, CGST Bengaluru North, on what the regulator actually expects from India's largest enterprises in 2026, and why most finance teams haven't caught up.
"We used to manage approximately 15 lakh taxpayers with the same manpower we now use for approximately 65 lakh. The system does not sleep. The moment a mismatch appears, the algorithm has already flagged it."
- Dr. Kotraswamy M., Commissioner, CGST Bengaluru North
