When Your DSC Expires

On the day after it expires, everything you sign with it stops. There is no grace period and no way to extend it.

What actually stops

Not gradually. A certificate is valid until a date and then it is not, and every portal that checks it refuses the signature from that moment.

If you file GST monthly, that stops. If you are mid-way through a tender, the submission stops. If you run an MP Online kiosk, the kiosk stops. The certificate is usually invisible until the day it is the only thing standing between you and a deadline.

Renewal is really a fresh certificate

  • An expired certificate cannot be extended. A new one is issued, with fresh video KYC.
  • The new certificate has to be registered again on every portal you use. Portals map to a certificate, not to you.
  • Same-day issue is normal, but it needs you available for the verification.
  • Nothing signed earlier is affected. Documents signed while the certificate was valid stay valid.

Written 5 September 2026. Government requirements and portal behaviour change — message us to confirm before you rely on any date or figure here.

The only real fix is a calendar entry

Check the expiry today and put it in the same place as your filing deadlines, with a reminder a month before. See our page on checking validity.

And buy longer validity next time. Two or three years costs less per year and removes an expiry event from your life entirely.

Common questions

Message us now rather than later in the day. Same-day is normal but it needs your two minutes for the verification, and portal re-registration after that.

No. Extension does not exist for these certificates. A fresh one is issued.

No. A signature made while the certificate was valid remains valid.
