GST Advisory on emSigner Version 3.3 and DSC Token Compatibility: 19 September 2026
The GST Portal issued an advisory dated 19 September 2026 providing advance information regarding the introduction of emSigner version 3.3 for taxpayers and tax officers using Digital Signature Certificates (DSCs) on the portal. The new version is intended to ensure compatibility with USB dongles issued on or after 21 September 2026. Users with existing valid DSCs whose tokens continue to function normally may continue using their current emSigner version.

Users receiving new or renewed DSC tokens on or after 21 September 2026 are required to upgrade to emSigner
