Notices
Changes and requirements worth knowing about before they affect a filing, a certificate or a token. Each one links to the page that explains it in full.
Everything we are currently flagging
Every notice we have out, across GST, income tax, Digital Signature Certificates and tokens.
- GST · DSC
emSigner 3.3 is mandatory for all FIPS 140-3 hardware tokens — if you are using a FIPS 140-3 compliant hardware token, you must download and install emSigner 3.3.
- Income Tax
The Income Tax Act, 2025 has been in force since 1 April 2026 — "Assessment Year" is gone, replaced by "Tax Year", and sections and form numbers have changed.
- DSC
Class 3 is the only class of Digital Signature Certificate still issued — a Class 2 certificate cannot be renewed as one.
- eSign
Aadhaar eSign does not replace a Class 3 certificate on statutory portals — income tax, GST, MCA21 and e-tendering all require Class 3.
- Tokens
Every certificate we issue is installed on a FIPS 140-3 compliant USB crypto token — a certificate cannot be copied off one.
- Drivers
The HYP2003 Windows installer is now a direct download — the supplied build is the initialisation utility, which erases the certificate on a token, so read the caution beside it. macOS and Linux builds are still sent on request.
