MCA e-forms must be signed with the DSC of the director, company secretary or other authorised signatory. When signing fails on the MCA21 V3 portal, the reason is usually the signer program, the browser or the certificate itself.
Check the basics first
- The DSC is Class 3 and not expired.
- The name and PAN in the DSC match the signatory in the form.
- The token is plugged in and detected.
Fix signing problems
- Install the signer utility the portal asks you to download and run it as administrator.
- Use Chrome or Edge, allow pop-ups and downloads for the MCA portal.
- When the certificate list appears, select your signing certificate and enter the token PIN.
- If the certificate list is empty, close the browser, restart the signer, reconnect the token and try again.
Director DSC not linked to DIN
Directors should keep the same name and PAN on their DSC as on their DIN record. A name mismatch can cause signing to be rejected.
After you renew
Update the DSC details in your profile and make sure the form uses the newer certificate. Details are in our renewal guide.
