When you need a DSC, what class to get, and how to manage certificates across your team — explained simply.
Digital Signature Certificates (DSCs) have become essential for Indian businesses. From MCA filings to GST returns, most government e-filing portals now require a valid DSC for authenticated submissions.
What is a DSC?
A Digital Signature Certificate is the electronic equivalent of a handwritten signature. It provides authentication, integrity, and non-repudiation for electronic documents. DSCs are issued by licensed Certifying Authorities under the Information Technology Act, 2000.
Classes of DSC
Class 3 DSCs are required for most business filings — MCA, Income Tax, GST, EPFO, and tender submissions. Class 2 DSCs were phased out in 2021 and all new issuances are Class 3.
Who needs one?
Company directors (for MCA filings), authorised signatories (for GST returns), EPFO authorised signatories, and anyone filing e-tenders or e-procurement documents.
A common mistake is getting a DSC for just one director. All directors who sign annual returns and authorised signatories for GST, EPFO, and other portals need their own individual DSCs.
Managing multiple DSCs
For organisations with multiple directors and signatories, DSC management can become complex. Track expiry dates centrally, ensure tokens are stored securely, and initiate renewals at least 30 days before expiry.
