How to register DSC on new Income Tax Portal

The e-filing users require a Digital Signature Certificate (DSC) to sign the income tax returns, forms and other places where authentication of the user on the electronic document is required. Hence, DSC serves as a proof of identity for an individual or an organisation for online purposes.

A Digital Signature Certificate is mandatory for certain taxpayers or to avail some services. The companies and political parties have to e-verify their income tax return through the digital signature certificate. Also, the persons whose books of accounts require a tax audit should e-verify their income tax returns. For others, it is optional.
