Kerala's state GST department Special Investigation Team has quantified ₹25.78 crore in tax dues against Reporter Broadcasting Company Pvt Ltd, after detecting a mismatch between the turnover declared in GST returns and actual taxable turnover. The SIT found discrepancies in the company's filed returns versus its actual revenue, triggering a demand for unpaid GST along with applicable interest and penalty under the GST law's enforcement provisions.

A GST turnover mismatch occurs when the revenue a business declares in its GST returns (GSTR-1, GSTR-3B) differs from the turnover established through investigation — cross-referencing bank statements, income tax filings, TDS data, or third-party sources. This is precisely what Kerala's SIT uncovered at Reporter Broadcasting Company.

For NABARD aspirants, this case illustrates how state GST enforcement works in practice. Under the GST architecture, both Centre and States share enforcement jurisdiction. States administer GST for taxpayers with turnover below ₹1.5 crore primarily, and state GST departments maintain their own audit and investigation wings — including SITs for complex cases.

The transmission mechanism matters here: when GST dues go underpaid by businesses, state revenues are compressed, reducing funds available for rural welfare schemes, agricultural infrastructure, and state-sponsored credit-linked programmes that NABARD refinances. States with stronger GST compliance report higher Own Tax Revenue, which improves their fiscal capacity to co-fund centrally sponsored schemes.

The GST mismatch detection process typically involves comparing GSTR-2A/2B (auto-populated purchase data) with GSTR-3B (self-declared liability), and cross-checking GSTR-1 (outward supply details) with actual collections. Unexplained gaps attract scrutiny under Section 61 (scrutiny of returns), Section 65 (audit), or Section 67 (inspection/search) of the CGST Act. Demand and recovery follow under Sections 73–74, with interest at 18% per annum and penalty up to 100% of tax in fraud cases.
