It is mandatory for Government deductors, who are reporting TDS without payment through bank challans, to quote correct Book Identification Number (BIN), while filing TDS/TCS statement. In case correct BIN is not quoted in the respective TDS statement, a Short Payment demand shall be raised by CPC(TDS).
BIN is generated by the Tax Information Network (NSDL) once the respective Principal Accounts Officer files monthly statements in Form 24G. You may contact your respective PAO/ AO/ AAO/DTO/ TO/ CDO and collect the BIN details. You can also check BIN from TIN portal at https://onlineservices.tin.egov-nsdl.com/TIN/JSP/etbaf/ViewBIN.jsp
