What began as a routine inspection of biryani outlets in Hyderabad in November 2025 has since grown into one of the largest tax enforcement actions ever directed at India’s food and beverage industry. On March 8, 2026, India’s Income Tax Department conducted a coordinated nationwide survey across restaurants in dozens of cities, deploying artificial intelligence and big data analytics to expose a systematic pattern of revenue concealment now being referred to as the “vanishing bill trick.”
The scheme works by deleting or editing records of cash transactions within restaurant billing software, effectively removing a day’s or month’s revenue from the books entirely. The result: lower declared turnover, reduced income tax liability, and suppressed GST obligations. Several establishments were found deleting bulk bills and making software modifications to suppress actual sales, leading to under-reporting of turnover in income tax filings, according to a press release issued by India’s Central Board of Direct Taxes (CBDT) on March 9, 2026.
The investigation’s reach is significant. Using advanced analytical tools, the department examined transactional data from approximately 1.77 lakh restaurants and compared it against income declared in tax returns. The follow-up survey on March 8 covered 62 restaurants across 46 cities in 22 states, revealing a preliminary suppression of sales amounting to nearly Rs 408 crore, with investigations continuing.
The true scale of the problem, however, is believed to be far larger. Preliminary data suggests that the suppression of turnover based on hard data examined by authorities stands at around Rs 13,000 crore, which could extrapolate into a potential Rs 70,000 crore in tax evasion across the industry since the 2019-20 fiscal year. Investigators processed approximately 60 terabytes of data linked to a billing platform reportedly used by over one lakh restaurants, and officials have noted this covers only one software provider. Other billing platforms widely used across the hospitality sector may face similar scrutiny.
State-wise data showed Karnataka recording the highest deletion figures at around Rs 2,000 crore, followed by Telangana at Rs 1,500 crore and Tamil Nadu at Rs 1,200 crore, with Maharashtra and Gujarat rounding out the top five states where evasion was detected. Survey teams visited establishments across a sprawling geography spanning Mumbai, Pune, Gurugram, Lucknow, Chennai, Coimbatore, Madurai, Bengaluru, Indore, Shimla, Amritsar, Jaipur, Kolkata, Guwahati, and Patna, among others.
The enforcement action has been paired with an amnesty-style compliance push. The government’s SAKSHAM NUDGE campaign encourages flagged businesses to file updated returns voluntarily by March 31, 2026, under Section 139(8A) of the Income Tax Act, with authorities signalling that stricter enforcement action will follow for those who do not comply after the deadline passes.
The probe marks a turning point for the foodservice sector globally, not just in India. As governments across markets invest in AI-powered transaction surveillance, the ability for high-volume, cash-adjacent businesses to obscure revenue is narrowing rapidly.
