How does the taxpayer verify the genuineness of the notice received?
Very soon a facility will be provided for verification of the genuineness of the notice from the DIN mentioned in the notice. The taxpayer will be enabled to verify the DIN from the e-portal and see if the notice is genuine by clicking on the Authenticate Notice/Order Issued by ITD link in the Quick Linkssection found in the e-portal and following the process as mentioned in the e-portal.

The taxpayer has to furnish the response to the notice only through the Compliance Portal of the Income Tax Department https://eportal.incometax.gov.in and not through email. The instructions for furnishing the information are mentioned in the Annexure-2 of the notice issued to the taxpayer.
