What is a Digital Signature for GST?
A Digital Signature Certificate (DSC) is mandatory for companies and LLPs to register and file returns on the GST portal (gst.gov.in). A Class 3 DSC lets you authenticate every GST submission online, with the same legal validity as a handwritten signature.
While proprietors and individuals can use the EVC (OTP) option, a DSC is the faster, more reliable way to file — especially during peak return-filing periods. SignSecure issues GST-ready Class 3 certificates through a 100% paperless Aadhaar eKYC process within a day.
