With an increase in the use of technology to accomplish various tasks, there has also been an increase in newer ways to help achieve them. One such development is the introduction of digital signatures by the Income Tax Department for filing e-returns. 

Digital Signature (DSC) is an electronic form of signature used to sign documents digitally to authenticate both the signatory of the document and the electronic document itself. This brings us to the point in the discussion- DSC Utility. DSC or Digital Signature Certificate can be used to:

  1. To file Income Tax Return
  2. To register for PAN
  3. And to file TDS returns online

DSC, is thus, a secure and hassle-free process to file returns online. Digital Signature certificate has a validity of one to two years and can be renewed upon expiry.
