Mumbai, Jan 31 (PTI) The Income Tax Department on Thursday conducted a survey operation at the premises of some broking companies as part of an alleged tax evasion probe against Jane Street, the US-based proprietary trading firm accused of market manipulation, official sources said.

Sources stated the department is undertaking a "verification" exercise in the backdrop of a recent Sebi action against Jane Street.

In an interim order issued on July 3, Sebi found Jane Street (JS) guilty of manipulating indices by simultaneously placing bets in cash along with futures and options markets to secure massive gains.

As a result, Sebi barred the hedge fund from accessing the market and impounded over Rs 4,843 crore in gains. The probe found that JS made a profit of Rs 36,671 crore on a net basis during the probe period from January 2023 to May 2025.

However, on July 21, Sebi permitted Jane Street to resume trading after the company deposited the mandated amount of Rs 4,843.57 crore into an escrow account. PTI NES MPL MPL

Market manipulation probe prompts tax verification and surveys at broker premises following securities regulator action. A tax verification survey was conducted at broking premises by the Income Tax Department in connection with an alleged tax-evasion inquiry tied to a US proprietary trading firm, prompted by a securities regulator's interim order finding coordinated market manipulation across cash, futures, and options. The regulator barred the firm from market access and impounded gains during the probe period; trading was later allowed after the firm deposited the mandated amount into an escrow account.
