What is a DSC for GST?
A Digital Signature Certificate for GST is a Class 3 DSC used to digitally sign GST registration applications and periodic returns on the GST portal — mandatory for Companies, LLPs, and Foreign Limited Liability Partnerships under CGST Rule 26.
Proprietors and many individuals may be able to use EVC, but companies and LLPs generally need DSC for GST authentication.
GST portal signing can fail because of token drivers, browser settings or mismatched signatory details, so setup support matters after issuance.
