What Is a Digital Signature Certificate (DSC) and Why Is Renewal Necessary?
A Digital Signature Certificate is a secure digital key issued by certifying authorities to authenticate your identity electronically. It’s required for:
-
Income tax filing
-
MCA ROC filings
-
EPFO transactions
-
E-tender submissions
-
Company registration
Since DSCs are valid for a limited period (1–3 years), renewal becomes necessary to maintain uninterrupted service. Failing to perform a DSC validity check may lead to denied access or application failures. That’s why understanding how to renew digital signature ahead of time is crucial.
When and How to Check Your DSC Validity
The first step in managing your DSC is to perform a DSC validity check. Here’s how:
-
Plug in your USB token with the DSC

Open the DSC management tool provided by your CA (e.g., eMudhra, Capricorn, VSign)

Go to Certificate Details
-
Check the “Valid Until” date under certificate status
Once you notice your DSC is close to expiring (within 30 days), it’s time for your online DSC update. You don’t need to reapply from scratch — the renewal is a faster, streamlined process.
