Digital Signature for GST

When is a DSC used on the GST portal?

The GST portal supports digital signature-based authentication for specified activities and user categories. Whether a DSC is mandatory or optional depends on the taxpayer type, authorised signatory and transaction being performed.

General registration steps

1. Confirm that the authorised signatory and DSC details are correct.
2. Install the required token driver and portal signing utility, if applicable.
3. Connect the USB token and ensure the certificate is visible to the system.
4. Sign in to the GST portal and follow its current DSC registration or signing instructions.
5. Choose the correct certificate and enter the token PIN when prompted.

Common troubleshooting checks

• Confirm the token is detected and its driver is correctly installed.
• Check certificate validity and whether it belongs to the authorised signatory.
• Use a supported browser and the current portal signing utility.
• Restart the browser or system after installing or updating components.
• Read the exact error message before changing security settings.
