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.

DSC OR EVC

DSC vs EVC in GST — which one must you file with?

An EVC is a one-time code sent to the authorised signatory's registered mobile and email. A DSC is a physical Class 3 USB token issued against their PAN. Which one the GST portal will accept depends on your entity type, not your preference.

If you pick the wrong oneThe portal blocks submission — the EVC option is simply not offered, so the filing cannot be completed until a valid DSC is registeredNo harm in holding a DSC anyway; EVC stays available where the portal offers itA return left unfiled while you sort out signing still attracts late fees and interest

Fast answersExpert support
  • In GST, an EVC (Electronic Verification Code) is a one-time code sent to the authorised signatory's registered mobile number and email, while a DSC (Digital Signature Certificate) is a physical Class 3 USB token issued against that person's PAN. Both authenticate a filing on the GST portal, but only a DSC is a legally recognised digital signature under the Information Technology Act. Which one you may use is decided by your entity type, not by preference.
  • File with a DSC if you are a company, an LLP or a Foreign LLP, because the GST portal does not offer the EVC option to those entities at all. Proprietors, most partnerships and other taxpayers can usually submit with EVC, which is faster because it needs no token, no driver and no browser utility. If you hold a valid DSC you may use it in either case.
  • Nothing is rejected or penalised — the GST portal simply will not present the EVC option, so the submission cannot be completed. The practical risk is the delay: a GSTR-1 or GSTR-3B left unfiled while a token is arranged still attracts late fees and interest from the original due date, so a company should arrange its signatory DSC before the deadline rather than on it.
  • DSC is mandatory for GST registration by companies, LLPs and Foreign Limited Liability Partnerships. Other taxpayers may have EVC options depending on constitution.
  • A proprietor can often use EVC or Aadhaar-based verification instead of DSC, subject to GST portal options available for the taxpayer.
  • A valid Class 3 Signing DSC issued to the authorised signatory is generally used on the GST portal.
  • GST filing usually needs Signing DSC, not Sign+Encrypt combo, unless another linked portal requires encryption.
  • Yes, if issued to the same authorised person and accepted by both portals, one Class 3 Signing DSC can often be used on GST and MCA.
  • Common reasons include expired certificate, wrong signatory, missing token driver, browser issue or portal utility error.
  • LLPs generally need DSC authentication for GST portal filings and returns.
  • Yes, the GST authorised signatory can be updated and a DSC issued to the new authorised person can be used.
  • Most GST DSC applications are issued the same day or within 1 working day after verification is complete.
  • DSC uses a USB token-based certificate, while e-Sign or EVC uses OTP-style authentication where permitted by GST rules.
