डीएससी क्या है?

अन्य नाम: Digital Signature Certificate

डीएससी यूएसबी टोकन पर मौजूद वह डिजिटल प्रमाणपत्र है जो एमसीए, आयकर और जीएसटी पोर्टल पर वैध इलेक्ट्रॉनिक हस्ताक्षर के रूप में काम करता है।

Class 3 is the grade required for company and tax filings. Certificates are issued by licensed certifying authorities for one or two years and must be renewed before expiry.

The token is physical and the private key never leaves it, which is what makes the signature legally equivalent to a handwritten one under the Information Technology Act.

क्यों मायने रखता है

A DSC expiring unnoticed stops every statutory filing that needs a signature — usually discovered on the day of a deadline.

इसे इनसे न मिलाएँ

ये शब्द अक्सर एक-दूसरे के लिए इस्तेमाल कर लिए जाते हैं। ये अलग हैं।

E-signature on the income tax portal

Aadhaar OTP verification on the income tax portal is a different mechanism and is not accepted for MCA filings, which need a Class 3 DSC on a hardware token.

A scanned signature

An image of a signature has no legal standing under the IT Act. A DSC is a cryptographic certificate tied to a token you physically hold.

आम सवाल

What happens when it expires?

Every filing that needs it stops until it is renewed, and renewal is a fresh issuance with verification rather than a click. Expiry dates cluster because certificates are usually bought together at incorporation — worth diarising before a filing deadline finds it.

Can two people share one DSC?

No. A DSC is tied to one individual and signing with someone else's is a misrepresentation. Each director and each authorised signatory needs their own.

जो अक्सर ग़लत होता है

Discovering the expiry on the day of an annual filing deadline
Registering the DSC on the MCA portal against the wrong DIN, so filings are rejected
Buying a Class 2 certificate, which is no longer accepted for MCA filings
Losing the hardware token, which means a fresh issuance rather than a recovery
