About Our DSC Service

Your Certificate, Issued Without the Hassle

A Digital Signature Certificate is what makes your electronic filings legally binding — it's the digital equivalent of a handwritten signature, encrypted and tied to your identity, recognised by the MCA, Income Tax Department, GSTN, and e-tendering portals.

Our team handles the entire process: document verification, video KYC coordination with the certifying authority, application submission, and delivery of your USB crypto token. If your DSC needs renewal before it expires, we track that too and remind you in advance.

Who Needs a DSC

Is a Digital Signature Mandatory for You?

A DSC is legally required for certain filings, and simply more convenient and secure for many others.

Company & LLP Directors

Every director or designated partner needs a DSC to sign incorporation forms, annual returns, and other filings submitted to the MCA.

GST Registered Businesses

Companies and LLPs must use a DSC to sign GST registration applications and periodic GST returns on the GSTN portal.

E-Tender Applicants

Bidding on government and PSU tenders through e-procurement portals requires a valid Class 3 DSC for submission and signing.

Trademark & IP Filers

Filing trademark, patent, or copyright applications online through the IP India portal requires the applicant's DSC.

Income Tax Audit Cases

Taxpayers whose accounts are subject to audit must verify their income tax return using a DSC instead of other e-verification methods.

Anyone Signing Documents Securely

Professionals who want to sign contracts, invoices, or PDFs with a tamper-evident, legally recognised signature use a DSC even where it isn't mandatory.

Class 3 is the standard requirement today for MCA, GST, income tax, e-tendering, and trademark filings. We confirm whether you need a Signing-only or Sign + Encrypt combo certificate based on the portal you're using.
