The income-tax (I-T) department has asked stockbrokers to remit excess securities transaction tax (STT) collected from clients for 2023-2024 (FY24) and earlier years, along with interest, if the amount has not yet been deposited with the government, according to a circular issued by the National Stock Exchange (NSE). In a letter dated March 5 to the NSE, the I-T department highlighted that certain brokers and sub-brokers had collected STT in excess from clients but had not remitted the amount to the government account for FY24 and preceding years.
