Why It Matters
Everything you need for GST compliance
Companies, LLPs and partnership firms must sign GST filings with a Class 3 Digital Signature Certificate, as the GST portal does not accept Aadhaar-based e-sign for entities. TNIT DSC issues Class 3 certificates for the authorised signatory named on your GST registration, covering new registration under REG-01, outward and inward returns, refund applications and amendment filings. Certificates are issued the same working day, fully paperless.
01
Accepted on the GST portal
Class 3 certificates issued through a licensed Certifying Authority and recognised for GST registration and return filing.
02
Registered for the authorised signatory
The certificate is issued in the name of the person registered as the authorised signatory on your GST record, so filings are accepted without rework.
03
One certificate for every GST task
Registration under REG-01, GSTR-1 and GSTR-3B returns, refund claims, amendments and cancellation requests all use the same DSC.
04
Organisation certificates for entities
Companies and LLPs get organisation certificates backed by company PAN and the incorporation certificate, not just an individual certificate.
05
Renewal reminders
We flag your expiry date in advance so a lapsed DSC never blocks a filing deadline. Renewal can be completed before expiry without a new application.
06
Works with your accounting workflow
If your CA or accountant files on your behalf, we can issue the certificate in the signatory's name and guide them through installation.
