DSC Registration on GST Portal

This article will assist you in understanding the step by step process of registering a digital signature certificate on the GST portal

In India, the digital era is prevailing and the country’s new tax regime i.e. Goods and Service Tax (GST) is also not left untouched. Digital signatures were already being used with income tax returns and ministry of Corporate Affairs and thereafter the government introduced the digital signatures and online filing for GST returns (GSTR) as well. This has proved to be helpful for those dealers who are having a business in different states and union territories of India as manual signing and filing will make the compliance process very complicated and time-consuming.

Digital signature certificate

Digital Signature Certificates are the digital equivalents of physical or paper certificates. For example drivers’ licences, passport, etc. are physical certificates which act as proof of identity for the specified purpose. Similarly, to establish the identity of a person, digital certificates can be presented electronically. Its main function is to digitally sign the documents. For example e-forms on various government sites for tax compliances etc.

Digital signatures are issued by licensed Certifying Authority. Certifying Authority means a person who has been granted a license to issue digital signature certificate u/s 24 of the Information Technology Act, 2000. The list and the contact information of the licensed Certifying Authorities are available on the MCA portal. To name a few:- National Informatics Centre, Sify Communication Ltd., E-MUDHRA, NSDL, etc.


DSC has replaced physical signatures and it is compulsory for companies, limited liability partnerships, PSUs and optional for other taxpayers to sign and file returns on GST portal. For this, the concerned person has to get a digital certificate from the Certifying Authority, which can be either Class 2 or a Class 3 signature (which comes with a validity of 1 year, 2 years and 3 years). Apart from GST, Class 2 Digital Signature may be used for ROC, EPFO, MCA21, Income Tax filings and many more. DSC comes in a USB token with password protection to ensure security.
