Overview
A Digital Signature Certificate (DSC) is a secure electronic authentication tool used to digitally sign online documents, applications, returns, and government filings. It acts as the digital equivalent of a handwritten signature and helps verify the identity of the person signing an electronic document. In India, DSC is widely used for online compliance, tax filings, e-tendering, MCA filings, GST authentication, trademark applications, and various government portal services.
An Individual DSC is specifically issued in the name of an individual person rather than a company or organization. It is commonly used by professionals, directors, proprietors, consultants, freelancers, and individuals involved in digital compliance activities.
At VardhanTax, we assist individuals, professionals, business owners, and consultants with DSC registration, renewal, token setup, and portal configuration support to help ensure smooth and secure digital compliance.
