An expired DSC cannot sign anything. The fix is to get a new certificate issued and register it on your portals.
What to do
- Check the expiry date in your token utility.
- Apply for a new DSC of the same type with Aadhaar eKYC. See how to renew.
- Confirm whether your token can take the new certificate. See old token guide.
- Register the new DSC on every portal.
Pending filing deadlines
Act the same day if a due date is close. A fresh DSC can often be issued within the day after KYC and payment.
Avoid it next time
Set a reminder 30 days before expiry and choose a longer validity if you file regularly.
