Digital Signature Certificate (DSC) – including DGFT DSC
A Digital Signature Certificate is the legal equivalent of your wet ink signature for every government filing in India — MCA company filings, GST portal submissions, Income Tax returns for companies and audit cases, DGFT export applications, and e-tender submissions.

A Digital Signature Certificate is the legal equivalent of your wet ink signature for every government filing in India — MCA company filings, GST portal submissions, Income Tax returns for companies and audit cases, DGFT export applications, and e-tender submissions. Without a valid Class 3 DSC, a company cannot file its annual returns, a director cannot be appointed, a contract cannot be submitted on the government procurement portal, and a CA cannot certify an audit. At PNPC Global, we obtain and renew DSCs for directors, partners, authorised signatories, and practising CAs as part of every incorporation and compliance engagement — because the DSC is not a standalone requirement, it is the signature infrastructure that makes every other compliance filing legally valid.
What it costs
No hidden charges. The exact figure is set in your engagement letter.
A Digital Signature Certificate (DSC) is an electronic document issued by a government-licensed Certifying Authority (CA) under the Information Technology Act 2000 and the IT (Certifying Authorities) Rules 2000. It contains the holder's identity information, their public key, and the digital signature of the issuing Certifying Authority — creating a cryptographically verifiable proof that a specific, authenticated individual signed a specific document at a specific time. DSCs in India are classified by use class. Class 3 is the current active class for all legal, regulatory, and government portal submissions — it involves the highest level of identity verification and is the only class accepted by MCA21, the GST portal, the Income Tax e-filing portal, DGFT, and the Government e-Marketplace (GeM). The DSC is physically stored on a USB crypto token (dongle) issued by the Certifying Authority — the private key never leaves the device. When you sign a filing, the token generates the signature locally using your PIN-protected private key.
When a Class 3 DSC is required
Company incorporation — SPICe+ filing on MCA21 requires DSC of all proposed directors; a Class 3 DSC is mandatory
All MCA annual filings — AOC-4 (financial statements), MGT-7 (annual return), ADT-1 (auditor appointment) — signed by director DSC
LLP incorporation and annual filings — FiLLiP, Form 3, Form 8, Form 11 — signed by designated partner DSC
GST filings where DSC authentication is required — used by companies (non-individuals) who opt for DSC-based portal authentication
Income Tax returns and audit reports — ITR-6 (companies), audit reports under Sections 44AB, 92E — signed by director and tax auditor DSC
DGFT applications — Advance Authorisation, EPCG, IEC amendments for company entities
e-Tender submissions on CPPP, GeM, and state government procurement portals — DSC-signed bids
Practising Chartered Accountants — required for certifying audit reports, financial statements, and compliance certificates submitted to government portals
All MCA director-level forms — DIR-3 KYC, DIN allotment, DIR-12 for director changes, SH-7 for capital changes
When a Class 3 DSC may not be necessary
Udyam MSME registration — uses Aadhaar OTP authentication only; a DSC is neither required nor accepted in the Udyam process
Individual Income Tax return filing (ITR-1, ITR-2, ITR-4 for individuals) where e-verification via Aadhaar OTP, net banking, or bank account is sufficient — DSC is one option but not mandatory
GST registration for individuals and proprietors using Aadhaar OTP authentication — DSC is an alternative, not a requirement
Proprietorship or individual filings where OTP-based e-verification is available and sufficient for the specific portal
| Feature | Class 3 DSC (Individual) | Class 3 DSC (Organisation) | Document Signer (Bulk) | eSign (Aadhaar-Based) |
|---|---|---|---|---|
| Who holds it | Named individual | Named individual acting on behalf of organisation | Organisation-level system account | Any Aadhaar-linked individual |
| Identity verification | Aadhaar eKYC + video verification | Aadhaar eKYC + video + organisation proof | As prescribed by CA for bulk systems | Aadhaar OTP (real-time) |
| Physical token | USB crypto token issued by CA | USB crypto token issued by CA | HSM/server-side | No token — online signature |
| MCA filing acceptance | Yes | Yes | No — not for individual director filings | No — not accepted by MCA21 |
| DGFT filing | Yes | Yes | Not applicable | No |
| Validity | 1, 2, or 3 years | 1, 2, or 3 years | Per CA agreement | Per transaction only — no reuse |
| Cost range (approximate) | ₹1,200–₹2,500 depending on validity | ₹1,500–₹3,000 depending on validity | Higher — volume pricing | Per-use nominal fee via NSDL/CDSL |
| Use case | All regulatory filings — MCA, GST, IT, DGFT | Same as individual + organisation identity | Mass document signing workflows | One-time agreements, bank KYC |
All fees are approximate and vary by Certifying Authority (eMudhra, Capricorn, etc.) and validity period chosen. PNPC obtains DSCs through licensed CAs and passes the cost through without markup. eSign via Aadhaar is not a substitute for a Class 3 DSC on MCA, DGFT, or Income Tax portals.
| # | Stage & What PNPC Does | What First-Time Applicants Often Miss | Timeline |
|---|---|---|---|
| 1 | Identity and Aadhaar readiness check | The DSC Aadhaar eKYC process requires an Aadhaar linked to a mobile number that is active and accessible at the time of video verification. An Aadhaar linked to an old, inactive SIM — common among NRI applicants — will fail OTP delivery and halt the process. PNPC checks Aadhaar mobile linkage status before scheduling the video call. | Day 1 |
| 2 | Certifying Authority selection and application initiation | PNPC works with licensed Certifying Authorities — primarily eMudhra and Capricorn — who are authorised by the Controller of Certifying Authorities (CCA) under the IT Act. The applicant's name, Aadhaar number, PAN, and email are submitted to the CA's portal to initiate the application. The Certifying Authority's name is embedded in the DSC and visible on every signed document. | Day 1 |
| 3 | Aadhaar eKYC and video verification | The applicant completes a brief video verification with the Certifying Authority's representative — typically 5–10 minutes, done on a smartphone. The purpose: confirm that the physical person matches the Aadhaar identity and the application. The video is retained by the CA as per CCA guidelines. For NRI applicants or applicants outside India, this is done remotely by video call. PNPC schedules and coordinates this step. | Day 1–2 — verification completed same or next day |
| 4 | USB crypto token configuration and delivery | After verification, the Certifying Authority configures the DSC onto a crypto USB token (e-Pass token or similar). The token is physically delivered to the applicant — courier to the address on record. The token includes a PIN set by the applicant during first use. PNPC provides guidance on setting the PIN and testing the DSC on the relevant portal before the first filing. | Day 3–5 — token delivered by courier |
| 5 | Portal registration and first-use testing | Different portals require DSC registration: on MCA21, the DSC is mapped to the DIN; on TRACES, mapped to the TAN; on the GST portal, to the GSTIN. PNPC assists with portal-specific DSC mapping after token delivery, and tests a dummy signature before the actual first filing to confirm the token and PIN are working correctly. | Day 5–7 — prior to first filing |
| 6 | Renewal tracking (before expiry) | A DSC expires at the end of its validity period — 1, 2, or 3 years. An expired DSC cannot sign any filing. The renewal process mirrors the original application and takes 3–5 days. PNPC tracks DSC expiry dates for all clients on the compliance calendar and initiates renewal 30 days before expiry — not the day after an MCA filing is rejected due to expired DSC. | Ongoing — renewal initiated 30 days before expiry |
A new DSC takes 3–7 working days from initiation to delivered crypto token in most Indian cities. For time-sensitive filings, initiate at least two weeks before the deadline. Renewal should be initiated 30 days before expiry.

| Phase | Trigger | PNPC CA Action | Risk If Ignored |
|---|---|---|---|
| First issuance | Company incorporation, LLP filing, first MCA/GST/IT submission | Aadhaar readiness check, CA selection, application initiation, video verification coordination, token delivery, portal mapping. | Filing cannot proceed. Incorporation delayed. Compliance deadline missed. |
| First portal mapping | Token delivered | DSC mapped to DIN on MCA21, GSTIN on GST portal, TAN on TRACES as applicable. Test signature performed before first live filing. | Portal rejects DSC at filing time — typically discovered at deadline pressure. |
| Expiry renewal | 30 days before expiry | PNPC initiates renewal — same process as initial issuance. Token reconfigured or replaced. | Expired DSC discovered at filing time. MCA/GST/DGFT form submission fails. Emergency renewal under time pressure. |
| Director/Partner change | New director or partner appointed | New DSC obtained for incoming director/partner. New DSC mapped to their DIN/DPIN on relevant portals. | Company/LLP forms requiring new director signature cannot be filed. |
| Token loss or damage | Crypto token lost, broken, or PIN locked | Report to Certifying Authority. Revoke compromised DSC. Reissue process initiated with fresh application. | Locked or compromised DSC creates filing suspension until reissued. PIN lock after too many attempts is common — PNPC advises on PIN management. |
| Revocation (security compromise) | Suspected unauthorised use or token theft | Immediate revocation request to issuing Certifying Authority. Replacement DSC initiated. | An unrevoked compromised DSC could be used to sign documents or filings fraudulently — potential legal liability. |
| Practitioner retirement / resignation | CA or director ceases to act | DSC revoked. Company filing signatory updated via MCA. New authorised signatory DSC obtained. | Outstanding filings signed by a no-longer-authorised individual may attract MCA query or rejection. |
What is a Class 3 DSC — and is there any other class I should know about?
Class 3 is the current active and mandatory class for all government portal submissions in India — MCA, GST, Income Tax, DGFT, and e-procurement. Earlier classes (Class 1 and Class 2) were used for lower-assurance purposes but have been discontinued for most regulatory filings. The Controller of Certifying Authorities (CCA) mandated Class 3 DSCs for all company and LLP MCA filings from 1 January 2021. If you have an older Class 2 DSC that has expired, it will need to be replaced with a Class 3 — not renewed in the old class.
Does every director of a company need a separate DSC?
For company filings, every director who needs to sign a form must have their own individual DSC. MCA21 forms are signed by specific directors — not by a generic company DSC. Typically, for annual filing purposes (AOC-4, MGT-7, ITR-6), the signing director plus the statutory auditor must each have a valid, unexpired Class 3 DSC. During incorporation, all proposed directors must complete DSC video verification. One director cannot use another director's DSC.
Can an NRI director get a DSC without coming to India?
Yes. The Aadhaar eKYC and video verification process is done remotely by video call with the Certifying Authority. For NRI directors who do not have an Aadhaar or whose Aadhaar is not linked to an accessible Indian mobile number, Certifying Authorities have an alternative process using Indian passport and notarised documents — the specific requirements vary by CA. The crypto token is then couriered to the applicant's address, including internationally. PNPC coordinates this process for all NRI directors.
What happens if a DSC expires mid-filing or just before an MCA deadline?
An expired DSC is immediately non-functional — the MCA21 system will reject it with an error. If discovered at an MCA deadline, you are looking at a late filing penalty (₹100/day, no cap) while the renewal is processed. Renewal takes 3–5 working days from initiation to token delivery. PNPC tracks DSC expiry dates for all clients and initiates renewal 30 days before expiry — ensuring there is always a valid DSC available for every deadline.
Can the same DSC be used for both MCA filings and GST portal submissions?
Yes. A single Class 3 DSC can be registered on multiple government portals — MCA21, GST portal, Income Tax e-filing, DGFT, and e-procurement portals — and used for signing on each. The DSC is not portal-specific. However, each portal has its own DSC registration process — the DSC must be mapped to your DIN on MCA21, your GSTIN on the GST portal, and so on. PNPC handles this cross-portal mapping after token delivery.
Is a DSC the same as an Aadhaar eSign or OTP verification?
No — these are distinct mechanisms. A DSC is a hardware-backed, privately held cryptographic certificate stored on a USB token. It creates a legally valid digital signature that binds your verified identity to a specific document. Aadhaar eSign is an online signing service that uses Aadhaar OTP for one-time transaction authentication. OTP-based portal verification confirms your identity for a session. Only the DSC creates a legally valid signature under the IT Act for company filings on MCA21 — Aadhaar OTP is not accepted by MCA21 for most director-signed forms.
What is the difference between a DSC for a director and a DSC for a CA?
A director's DSC is an individual Class 3 DSC that identifies the director by name and optionally by organisation. It is used to sign company forms, returns, and declarations on MCA21 and other portals. A practising CA's DSC is also a Class 3 DSC but may include the CA's ICAI membership number and 'practicing CA' designation — required for certifying audit reports and financial statements under Income Tax and MCA rules. The technical mechanism is the same; the embedded identity information and the regulatory contexts in which they are used differ.
What does the USB crypto token do — and what happens if I lose it?
The USB crypto token (e-Pass or equivalent) stores your private key in a tamper-resistant hardware chip. When you sign a document, the token generates the signature locally — your private key never leaves the device, even when connected to a computer. It is PIN-protected against unauthorised use. If the token is lost or stolen, the DSC must be immediately revoked by contacting the issuing Certifying Authority. A new DSC application and token are required. Revocation is permanent — it cannot be undone — but it prevents the lost token from being misused to sign documents fraudulently.
Which Certifying Authorities can issue a valid Class 3 DSC in India?
Only organisations licensed by the Controller of Certifying Authorities (CCA) under the IT Act can issue DSCs in India. The currently active licensed CAs include eMudhra, Capricorn CA, CDAC, NSDL e-Gov, and a few others. PNPC works primarily with eMudhra and Capricorn, both of which have established video verification infrastructure and nationwide courier delivery. The choice of CA does not affect the DSC's legal validity — all are equally accepted by all government portals.
How much does a Class 3 DSC cost?
Approximate market rates: ₹1,200–₹1,500 for 1-year validity; ₹1,800–₹2,500 for 2-year validity; ₹2,200–₹3,000 for 3-year validity. Prices vary slightly by Certifying Authority. These are the direct CA charges, passed through to the client. Longer validity is more cost-efficient per year and involves fewer renewal processes. PNPC recommends 2-year or 3-year validity for directors and professionals with ongoing filing obligations.
My company is being incorporated and we have two directors — when should DSCs be arranged?
DSCs should be arranged before the SPICe+ incorporation form is filed — both directors must sign the SPICe+ form with their individual Class 3 DSCs. The DSC process should start at least 7–10 working days before the planned SPICe+ submission to allow for video verification and token delivery. PNPC initiates DSC applications for all directors on Day 1 of the incorporation engagement, in parallel with name clearance and MoA drafting — ensuring no delay in the SPICe+ filing.
Can I use the same DSC token for multiple years, or does the token also expire?
The USB crypto token itself has a lifespan longer than the DSC validity period — the physical device is typically functional for 5–10 years or more. When a DSC expires, the same token can often be reconfigured with a renewed DSC by the Certifying Authority. However, if the token is lost, damaged, or incompatible with a new CA's system, a new token is issued with the renewed certificate. PNPC clarifies this with the issuing CA at renewal time — retaining the same token where possible saves cost.
