Get Started Today
A Digital Signature Certificate (DSC) is the electronic equivalent of a handwritten signature, used to sign online filings and documents. It is issued by a Certifying Authority licensed by the Controller of Certifying Authorities under the Information Technology Act, 2000. Directors, designated partners, professionals filing returns and businesses taking part in e-tenders use it for MCA forms, income tax and GST portal filings, DGFT applications and other government systems. Our team coordinates the application with a licensed Certifying Authority, helps with token setup and assists with registering the DSC on the relevant portals.
Who provides this service: our team of Company Secretaries and compliance specialists.

How It Works
Requirement check
We confirm who will sign, on which portals, and whether an individual signing certificate or an organisation certificate is needed, and choose the validity period offered by the Certifying Authority.
Document and name matching
We check that the name and details on the identity documents match the PAN and the portal profile, because mismatches are a common reason for rejection or failed portal registration later.
Identity verification
The Certifying Authority verifies the applicant through the method it supports, which may be Aadhaar-based e-KYC with OTP, a recorded video verification or attested paper documents, and we guide you through it.
Issue on token
After verification the certificate is issued on a secure USB cryptographic token. You set your own token password, which must be kept confidential and never shared with the person preparing your filings.
Driver setup and test signing
We assist with installing the token software on your computer and browser, and test the certificate so that issues with drivers or Java settings are found before a filing deadline, not during one.
Portal registration and renewal planning
We help register the DSC on the government portals where you file and record the expiry date, so a fresh certificate can be obtained well before the old one stops working.
Documents Required
- PAN card of the applicant
- Aadhaar card of the applicant, where Aadhaar-based e-KYC is used
- Mobile number linked to Aadhaar for OTP verification
- Recent passport-size photograph
- Active email address and mobile number of the applicant for the certificate record
- Proof of address, if the Certifying Authority asks for it in addition to Aadhaar
- Authorisation letter or board resolution on company letterhead, for DSCs issued to company representatives
- Organisation PAN and incorporation or GST details, for an organisation certificate
Timeline and Fees
Indicative timeline: Often within a few working days once documents and verification are complete. The range depends on the Certifying Authority and how quickly verification is finished.
Professional fee: The cost depends on the certificate type, validity period, whether a new token is needed and the Certifying Authority chosen. Our service fee is separate from the certificate and token charges. Contact us for a quote.
What Can Go Wrong if This Is Missed or Done Incorrectly
- Forms that require a DSC cannot be filed without a valid certificate, which can cause delay beyond due dates and additional fees on late filings
- Using an expired or revoked certificate can cause a filing to fail or be treated as invalid
- Sharing the token or its password with others creates a risk of unauthorised signing in your name
- Name or PAN mismatches can block portal registration and push back urgent filings
Frequently Asked Questions
What is a DSC and who needs one?
A DSC is a digital credential that lets a person sign documents and filings electronically with legal validity under the Information Technology Act. Company directors, LLP designated partners, auditors, tax professionals and tender participants commonly need one, because several government portals require a DSC for specific forms and applications.
Is Class 2 or Class 3 DSC issued now?
Class 3 is the certificate currently issued for these filings, as the Class 2 category was discontinued by the regulator for new certificates. Class 3 is accepted on the MCA, income tax, GST, DGFT and e-tendering portals. If a portal asks for a specific class, follow its current instructions.
How long is a DSC valid and can it be renewed?
Validity depends on the plan offered by the Certifying Authority, commonly one or two years. After expiry the certificate cannot be used for signing, and a new one must be obtained, usually through a renewal-style application with verification. Plan this a few weeks before expiry so that filings are not delayed.
Do I need a physical USB token for a DSC?
In practice yes. The private key is stored on a secure cryptographic token that cannot be copied, and portals expect signing to happen through it. The token is protected by a password you choose. Losing the token or forgetting the password usually means applying for a fresh certificate.
Can I use one DSC on MCA, GST and income tax portals?
Generally one valid Class 3 certificate can be used across portals, but it must be registered on each portal separately, and the name and PAN details must match. Some filings need the signatory to be a specific person, such as a director or authorised signatory, so confirm who must sign.
What if my name or details differ across documents?
Spelling differences between Aadhaar, PAN and the portal profile are a common cause of failed registration. Fix the underlying record first, such as correcting PAN details, or use the document set the Certifying Authority accepts consistently. Our team checks for mismatches before the application is submitted.
