India’s Income Tax Department has launched a survey operation at certain broking firms linked to alleged tax evasion by proprietary trading firm Jane Street, following regulatory findings of index manipulation.
On July 31, 2025, the Income Tax Department of India initiated a targeted survey operation across broking firms linked to Jane Street, a U.S.-based proprietary trading firm, following regulatory findings of significant market manipulation and alleged tax evasion.
According to senior officials, this operation is part of a broader “verification” exercise. It comes in the wake of recent actions by India’s capital markets regulator against the firm, where the company was found guilty of distorting key indices through synchronized trades in cash and derivatives segments, allegedly to harvest unfair gains.
The capital market regulator’s interim findings indicated that Jane Street netted profits of ₹36,671 crore over a span of nearly two and a half years, from January 2023 to May 2025. Following these revelations, the company was barred from participating in Indian markets and directed to deposit ₹4,843.57 crore—identified as unlawful gains—into an escrow account.

While the company has since complied with the order and been allowed to resume trading, the Income Tax Department’s survey suggests that the matter remains under intense scrutiny, particularly from a taxation and disclosure compliance standpoint.
Experts suggest that the survey may be a precursor to formal assessment proceedings, aimed at identifying discrepancies between declared income and actual trading gains. A senior financial analyst noted, “Such high-volume, high-frequency trades often attract attention not just for regulatory violations, but also for potential under-reporting or misclassification under income tax laws.”
This development also highlights India’s ongoing efforts to tighten surveillance over large foreign financial players operating within its capital markets, especially those using algorithmic or high-frequency trading (HFT) models.

The Income Tax Department of India has not issued an official statement on the operation yet, but sources close to the matter emphasized that the survey is evidence-driven and limited to data collection at this stage.
Jane Street, known for its complex trading strategies globally, has yet to make a public comment regarding the ongoing verification process by the Indian authorities.
The case underscores the growing alignment between regulatory and tax authorities in India, with a focus on transparency, fair play, and robust enforcement in capital markets.
