From Missing Biryani Bills To ₹70,000 Crore Shock: Inside India’s Massive Digital Tax Crackdown

New Delhi: A routine inspection at a handful of biryani restaurants in Hyderabad has snowballed into one of the country’s largest digital tax investigations, revealing an estimated Rs 70,000 crore in undisclosed sales nationwide.

The probe began late last year when Income Tax Department officials conducted standard checks at several eateries. While business appeared normal, officers noticed discrepancies between the number of customers dining in and the sales figures recorded in the billing systems.

Common Software, Nationwide Trail

What initially seemed like isolated irregularities soon took a bigger turn when investigators discovered that multiple restaurants were using the same billing software. Tracing the system’s backend to Ahmedabad, officials accessed nearly 60 terabytes of billing data from over one lakh restaurants across India.

Digital forensics teams began reconstructing deleted invoices at a specialised lab in Hyderabad. Although some transactions had been removed from front-end records, backend data logs retained traces of those entries.

AI Rebuilds Deleted Transactions

Using Artificial Intelligence tools, authorities analysed six years of billing data. The findings showed that restaurants had generated approximately Rs 2.43 lakh crore in bills during the period under review. Of this, more than Rs 13,000 crore worth of transactions had allegedly been deleted after being recorded.

Investigators found varied methods of suppression. Some establishments erased select cash bills daily, while others deleted records spanning several weeks. In other instances, businesses maintained full digital records internally but declared significantly lower turnover in tax filings.

State-Wise Impact

Preliminary analysis indicated that Karnataka had the highest value of deleted transactions at around Rs 2,000 crore, followed by Telangana at about Rs 1,500 crore. Tamil Nadu, Maharashtra and Gujarat also recorded substantial discrepancies.

In Andhra Pradesh and Telangana alone, scrutiny of 3,734 PAN-linked entities suggested suppressed sales exceeding Rs 5,000 crore. A focused review of 40 restaurants in these states revealed nearly Rs 400 crore in unreported turnover, with some outlets allegedly concealing up to 25% of their sales.

Investigation Expands

The Central Board of Direct Taxes (CBDT) has expanded the investigation beyond the initial states, noting that the findings so far relate to one billing platform and that other software systems may also come under review.

Officials are now cross-verifying reconstructed billing data with income tax returns and bank records. Notices and penalty assessments are expected to follow.

Experts say the case highlights how digital footprints remain traceable even when invoices are deleted. Investigators emphasise that modern data analytics and AI-driven scrutiny have made it increasingly difficult to conceal transactions in cloud-based accounting systems.

What started as a mismatch in biryani bills has ultimately exposed a vast network of alleged tax suppression—demonstrating the growing role of technology in detecting financial irregularities.
