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.
