After the e-return file has been uploaded successfully onto the Income tax Department server, a receipt is displayed with an acknowledgment number. The acknowledgment number is confirmation of the successful submission of your e-returns.
The receipt containing the acknowledgement number is the only valid proof of electronic submission of the return.
The assessee would be able to printout acknowledgement with an acknowledgement / ITR-V form in case of a successful upload. In case of any breakdown during the transmission of the XML file the assessee can re-submit the return. Further, assessee can verify the status in ‘My Return’ sub menu under the “My Account” menu. If the return had been uploaded successfully, copy of the acknowledgement will be available for taking printout. The acknowledgement sheet can also be reprinted under “My Return” sub menu after logging in.
