From Roadside Raids to Data Trails: Can GST Catch Fake Credit Without Burdening the Small Trader?

Following the Invoice, Not the Truck

GST's central promise was a seamless chain of credit. Each business pays tax on what it sells and claims credit for tax already paid on what it bought. That design is also its weak point. A credit claimed on a fake or misdescribed invoice reduces the tax a business pays in cash.

In FY26, CGST officers detected Rs 74,782 crore of fake input tax credit across 30,162 cases. That is about 27% more by value than the Rs 58,773 crore unearthed in FY25. For years the answer was physical enforcement: arrests, raids and roadside interceptions of goods vehicles.

After the 57th GST Council meeting, the answer is shifting to the data itself.

The mechanism:

matching both sides of the invoice The key tool is the Invoice Management System, live since October 2024. When a supplier uploads an invoice, the buyer can accept, reject or keep it pending. Only accepted invoices flow into the buyer's return and pending ones are deemed accepted when GSTR-2B is generated.

A proposed extra layer would make any reduction by a seller visible to the buyer, keeping both sides aligned. Linking input and output ledgers to the summary return is meant to catch fake credit as it arises rather than months later.

Officers have been told to look for two patterns:

• Retail sales booked as business sales, so that someone downstream can claim credit.
• Registered taxpayers who pay no tax in cash, offsetting their entire liability with ITC. The model is the Income Tax Department's NUDGE campaign, short for Non-intrusive Usage of Data to Guide and Enable. It flags anomalies and invites voluntary correction before any notice is issued.

Who gains and who carries the cost The honest mid-sized trader gains most. The Council recommended removing arrest powers under Section 69 and raising the prosecution threshold from Rs 1 crore to Rs 5 crore. It also recommended no show-cause notices below Rs 10,000 and a reduced 5% penalty in non-fraud cases paid within 30 days. Fewer coercive tools mean less room for harassment over minor errors. The transporter gains too. Vehicles may now be stopped only by officers of the supplier's or recipient's state, on specific intelligence and with authorisation, not by every state a truck passes through. The small retailer is the risk. B2B e-invoicing is mandatory today only for businesses with turnover of Rs 5 crore or more. B2C e-invoicing is due from 1 April 2027. Trade bodies warn that extending invoicing to retail could raise IT and compliance costs for small shops, the very businesses the reforms aim to spare.

The federal angle None of this happens by central order.

Under Article 279A, the GST Council brings the Union and States together and its recommendations carry persuasive rather than binding force. The transit rule shows the bargain at work. It was first proposed for supplier states only and recipient states were added at the request of some states during the meeting.

For the examiner, this marks GST's turn from enforcement to evidence. The test is whether technology can widen a base of about 1.68 crore taxpayers without shifting compliance costs onto those least able to bear them.
