How to get DIN under section 139(9)

This discussion addresses how to respond to a defective income tax return notice received under Section 139(9) of the Income Tax Act. The main challenge highlighted is the requirement for a Document Identification Number (DIN) to file the response, especially when the registered contact details are no longer accessible. It clarifies that DIN refers to a Document Identification Number, not a Director Identification Number, and explains that the response to a defective return notice must be filed through the e-filing portal. The CPC reference number, which is the ITR acknowledgement number, is also mentioned as important for this process.
