Q1. Is DSC mandatory for all businesses?

No, but highly recommended. DSC is mandatory for companies, LLPs, and businesses involved in e-tendering. For proprietorships and partnerships, it's required for specific filings like GST registration and income tax returns above certain thresholds.

Q2. What is the validity period of DSC?

Typically, DSCs are issued for 1 or 2 years. You need to renew your DSC before expiry to continue using it for digital signatures.

Q3. Can I use the same DSC for multiple purposes?

Yes, a single Class 3 DSC can be used for MCA filings, GST registration, income tax e-filing, and e-tendering, provided it meets the security requirements of all platforms.

Q4. What happens if my DSC expires?

Once expired, you cannot sign documents using that DSC. You need to apply for renewal before expiry to ensure uninterrupted usage.

Q5. Can I get DSC without Aadhaar?

Yes, but the process is more complex. Aadhaar-based e-KYC makes the process faster and completely online. Without Aadhaar, physical verification is required.

Q6. What should I do if I forget my DSC password?

You need to contact the Certifying Authority and follow their password reset process, which may involve re-verification of identity.

Q7. Is there any difference between DSC and digital signature?

Yes. Digital signature is the act of signing electronically, while DSC is the certificate that validates the identity of the signer and enables digital signatures.

Q8. Can I use mobile for DSC signing?

Yes, with specific apps and configurations. However, desktop usage is more common and widely supported across platforms.
