What is the difference between a Signing DSC and a Combo DSC?

A Class 3 Individual Signing DSC is used for tax portals like GST, ITR, MCA, and EPFO. It only supports digital signing. A Class 3 Combo DSC supports both signing and encryption — it is mandatory for e-tendering, GeM portal, e-auctions, and PSU procurement portals like ONGC, BHEL, and GAIL. If your portal requires bidding or participation in reverse auctions, you need a Combo DSC.

Which DSC do I need for GeM portal?

For GeM (Government e-Marketplace) seller registration and participation in reverse auctions and bidding, you need a Class 3 Individual Combo DSC. The price starts from ₹1,770 for 1-year validity. This is different from the Class 3 Signing DSC used for tax portals.

Can I use the same DSC for GST, MCA, and ITR?

Yes. A single Class 3 Individual Signing DSC can be used across multiple compliance portals including GST (gst.gov.in), MCA21 (mca.gov.in), Income Tax (incometaxindia.gov.in), EPFO, TDS, and ESI. You do not need a separate DSC for each portal.

What DSC is needed for e-tendering in India?

All government e-tendering portals (etenders.gov.in, state tender portals, PSU portals like BHEL, ONGC, NTPC, GAIL, Coal India) require a Class 3 Combo DSC with both signing and encryption capabilities. The price starts from ₹1,770 for 1-year validity.

Which DSC is required for DGFT and ICEGATE?

DGFT (dgft.gov.in) and ICEGATE (Customs eFiling) require a DGFT Class 3 Combo DSC, priced from ₹1,770 for 1-year validity. IEC Registration also requires this DSC type. This is different from the standard Class 3 Signing DSC used for tax compliance.

Can I use one DSC for multiple portals?

Yes. A single DSC can be used across multiple portals of the same type. A Class 3 Combo DSC works for GeM, all PSU tender portals (BHEL, ONGC, GAIL, NTPC, Coal India), state e-tender portals, and e-auction portals. You only need separate DSCs if you need different types (e.g., one Signing DSC for tax and one Combo DSC for tenders).

What is the validity of a DSC and can it be renewed?

DSCs are issued with 1-year, 2-year, or 3-year validity. A 2-year DSC offers the best value. After expiry, the DSC can be renewed online and downloaded to the same USB token. eFiling Infotech provides DSC renewal services at /dsc-renewal.

What is CERSAI DSC and why is it different?

CERSAI (Central Registry of Securitisation Asset Reconstruction and Security Interest) requires a Class 3 Combo DSC for both registration and document signing on cersai.org.in. CERSAI DSC is priced differently (from ₹1,652) from standard signing DSCs (₹826) due to the combo certificate requirement.
