<h1>Income Tax Survey Targets Brokerage Firm Under Section 133A for Market Manipulation Probe</h1> The Income Tax Department conducted a survey at the premises of a domestic brokerage firm partnered with a US-based proprietary trading firm as part of a tax evasion investigation linked to alleged market manipulation. The department is examining account books and electronic records under Section 133A of the Income Tax Act, following a regulatory action by the securities regulator, which found the US firm guilty of manipulating market indices and barred it from trading while impounding substantial gains. The domestic partner confirmed cooperation with the authorities and continued normal business operations. The US firm was allowed to resume trading after depositing the impounded amount into an escrow account. The investigation covers activities from January 2023 to May 2025 and involves scrutiny of financial transactions and compliance with market regulations.
