GST Annual Return (GSTR-9) requires a valid Digital Signature Certificate. In Kolkata, BestDSC has helped businesses obtain their DSCs along with High Trust Tokens. Our token-based DSCs reduce misuse risk and ensure only you can sign. We don't believe in selling cert-only options because misuse leaves you legally liable.

How the process works

GST Annual Return (GSTR-9) DSC application process: Online application + mobile/email OTP → video verification with vendor → certificate installed on High Trust Token → token couriered to your address. End-to-end in 1-3 business days for most Kolkata customers.

Why every certificate ships with a High Trust Token

At BestDSC we never sell a Digital Signature Certificate on its own. A certificate stored as a plain file can be silently copied, emailed or backed up without your knowledge — and once copied, it can be used to sign documents in your name. Every certificate we issue is installed on a High Trust Token, a tamper-resistant hardware cryptographic device (FIPS-certified), so your signing key physically never leaves the token.

This design prevents the most common form of DSC misuse. Because the private key is generated and locked inside the token, it cannot be exported or duplicated. Signing is only possible when the physical token is plugged in and unlocked with your PIN — giving you a clear, defensible audit trail for every signature.

The legal protection matters. Under the Information Technology Act, a digital signature carries the same legal standing as a handwritten one. Keeping the key on secure hardware means you can confidently attest that any signature made with your certificate was authorised by you — critical if a filing, tender bid or contract is ever disputed.

You get the token included, configured and delivered to your address. No separate purchase, no loose certificate files, and no compromise on security.

Frequently asked questions

Individual Class 3 Sign is ₹3,000 for 2 years, Organisation Class 3 Sign is ₹4,000 for 2 years — inclusive of the High Trust Token and courier. Since GSTR-9 is filed annually, one 2-year DSC covers 2 filings, making the per-filing cost low.

Companies, LLPs, and Foreign Companies MUST use a DSC — EVC is not permitted for these entities. If your GSTR-9 is stuck due to a missing DSC, we at BestDSC can issue a fresh Class 3 DSC and courier the token quickly.

Yes. GSTR-9 does not require the same DSC that filed monthly returns — any valid Class 3 DSC of an authorised signatory works. We at BestDSC issue a fresh 2-year DSC quickly so you can complete your annual filing without delay.

GSTR-9C requires two signatures — the taxpayer's DSC (which is yours) and the auditor's DSC. You use your own Class 3 DSC. The Chartered Accountant/CMA auditor uses their own DSC. We at BestDSC provide DSCs for both taxpayers and professionals.

Most courier services deliver Monday to Saturday. If your GSTR-9 deadline is close, plan the DSC application 5-7 days in advance to be safe. We at BestDSC send tracking updates so you always know when the token will arrive.

For the DSC itself, you only need PAN + Aadhaar of the authorised signatory at the time of applying. For GSTR-9 filing, additional records (books of accounts, invoices, HSN summary) are prepared separately. We collect DSC documents via WhatsApp/email after payment — no upload needed on our portal.

No. GSTR-9 must be signed by the authorised signatory registered on the GST portal — usually a director, partner, or authorised employee — using their OWN Class 3 DSC. You cannot use a personal DSC on the company's login.
