💡 How to Use Digital Signature on GST Portal (Made Easy!)

If you’re a business owner or CA dealing with GST returns, you’ve probably come across the Digital Signature Certificate (DSC). It’s like your online seal of approval, used to sign important GST documents securely.

Here’s a quick and simple guide to help you use your digital signature on the GST portal.


✅ Step-by-Step Guide to Use DSC on GST Portal

Step 1: Get a Valid DSC

Make sure you have a Class 3 DSC (usually USB token-based). It must be registered in the name of the authorized signatory as per your GST profile.

Step 2: Install DSC Software

Download and install the emSigner utility from the GST portal:

  • Visit www.gst.gov.in

  • Click ‘Register/Update DSC’

  • Choose your system type (Windows/Mac)

  • Install and run emSigner

Step 3: Register Your DSC on GST Portal

  • Log in to the GST Portal

  • Go to My Profile > Register/Update DSC

  • Select the PAN of the authorized signatory

  • Plug in your DSC USB token

  • Select the certificate and click ‘Register’

Step 4: Use DSC to File GST Returns

When filing GSTR forms (like GSTR-1, GSTR-3B):

  • Click ‘File with DSC’

  • emSigner will prompt you

  • Select the correct certificate and sign


🛠️ Common Issues?
