Why is Class 3 Mandatory?

Class 3 signatures replaced all legacy Class 2 categories following CCA circular updates. They operate with high cryptographic integrity (RSA 2048-bit keys & SHA-256 digests) and are mandatory for all core official Indian portals.

Includes: GST, MCA ROC, Income Tax (ITR), EPFO, and Central/State Tenders.

COMPLIANCE MAPPING

Regulatory Use Cases & Categories

Class 3 DSC is divided into "Signing Only" and "Combo" categories based on the security models of the target platforms.

Class 3 Signing Only

This certificate enables electronic attestation of digital PDFs, documents, or data payloads. It confirms the identity of the signatory and prevents tampering once signed. Highly recommended for tax filers and corporate directors.

Income Tax Return (ITR) E-Filing
GST Invoicing & Ledger Submissions
MCA ROC (Company Filings & Director KYC)
EPFO Provident Fund Approvals

Class 3 Combo (Signing + Encryption)

Contains separate certificates for both signing and encryption inside the same physical USB token. The encryption key protects pricing models and competitive numbers before open bid releases, ensuring high security.

Central Public Procurement (CPPP) Bidding
Government e-Marketplace (GeM) Auctions
Railway e-Procurement (IREPS) Tenders
State e-Procurement (Tenders/Auctions)

CLASS 3 DSC GUIDE

Who Should Apply for Class 3 Digital Signature?

Class 3 Digital Signature Certificate is required for high-assurance filing workflows across tax, corporate, and tender ecosystems in India.

At DSCDelhi.in, we support CA firms, CS professionals, company directors, MSMEs, startups, and procurement teams that need legally valid digital signing for GST returns, MCA ROC forms, ITR verification, PF filings, trademark submissions, and e-office approvals.

For government tender participation, many portals require Class 3 Combo DSC (Signing + Encryption) to protect commercial bid values before opening. If you need help choosing between Signing Only and Combo, our team maps your portal list and recommends the right certificate profile, validity, and token setup.

Class 3 DSC is also critical for internal governance where authorized signatories must approve contracts, declarations, and statutory records with auditable trust. Teams handling monthly or quarterly compliance should prioritize continuity planning so certificate expiry never collides with return due dates, audit closings, or bid openings.

DSCDelhi.in supports this lifecycle through onboarding checks, issuance monitoring, signer utility readiness, and renewal reminders. The goal is not only to issue the certificate, but to ensure your team can successfully sign and submit on real portals without last-minute technical blockers.
