Digital Signature Certificate (DSC): Why Every Director Needs One
Without a valid Class 3 DSC you cannot file SPICe+, GST, or income tax—budget ₹1,000–₹1,500 per director and renew before expiry.
January 05, 2024
What you'll take away
- Class 3 DSC on USB token is standard for MCA and GST filings.
- Two-year validity typical; renew 30 days before expiry to avoid filing lockouts.
- Video KYC providers issue DSC in 1–3 days with correct documents.
- Pelago provisions DSCs during incorporation so SPICe+ is not delayed.
What a DSC is
Digital Signature Certificate is your legally recognised electronic signature for government portals. Physical signatures are rejected for ROC, GST, income tax, and most tender submissions.
Stored on USB e-token (ProxKey, etc.) with PIN—treat like a debit card.
Class 3 and who needs it
Class 3 offers highest assurance—required for company incorporation, DIN-related filings, and GST for authorised signatories.
Every proposed director and subscriber typically needs DSC before SPICe+ or FiLLiP filing.
Founder tip: Keep one backup token if you have two directors—expired DSC on filing day is a common startup delay.
Uses across your stack
- MCA: SPICe+, DIR-3, MGT-14, annual forms.
- GST: Registration, GSTR filings, e-way bill (where applicable).
- Income tax: ITR verification, TDS returns.
- Tenders: e-procurement portals.
Application documents
PAN, Aadhaar, photo, email/mobile verification. Organisational DSCs need additional board resolutions.
Foreign directors follow certifying authority rules for passport-based KYC.
Security practices
Do not share PINs on Slack. Revoke tokens when directors exit. Pelago tracks expiry dates for retainer clients so compliance filings never stall on hardware.
