In an e-mail communication dated June 5, the department of income tax asked taxpayers to re-register their DSC or digital signature certificate afresh from June 7th onwards. The mail by the department read, "Please ensure that you re-register your current valid DSC on the new e-filing portal https://www.incometax.gov.in from June 7th onwards.
The earlier DSC registration on the old portal cannot be migrated due to security and technical reasons."

The department of income tax on June 7 unveiled a new platform e-filing 2.0 i.e. a highly interactive and advanced version aiming at simplifying the e-filing procedure and other tax related matters.
Along with the DSC re-registration, the department has also asked taxpayers to update their profile including mobile number, email under 'primary contact', respond in respect of 'outstanding demand' and in a case if there is any 'pending action' to take necessary step on them.
What is a Digital Signature Certificate?
A DSC is an electronic edition of physical certificate that validates the identity of an individual. In tax matters, it is used for signing the documents electronically and for authenticating the electronic documents. Depending on the nature of transactions and its various uses, DSC is issued with a validity period of 1 year or 2 years. After the validity expires, DSC needs to be obtained through a fresh application. In a case if there are any changes in the personal information, while applying for a fresh DSC you need to make an application to get the same updated on the DSC.
