Tax Filling India | Business Registration & Compliance Support
A Digital Signature Certificate (DSC) is the legal equivalent of your handwritten signature for electronic documents and filings. TaxFillingIndia issues your Class 3 DSC with a fully paperless process — no hard copies, no office visits, delivered the same day.
A Digital Signature Certificate is a secure digital key issued by a licensed Certifying Authority that verifies your identity electronically. Under the Information Technology Act, 2000, a DSC-signed document carries the same legal validity as one signed by hand.
DSCs are stored on a secure USB e-Token and are used to sign documents, forms, and applications submitted on government portals — from company incorporation to income tax filing.
Today, Class 3 DSC is the only class issued in India, valid for all levels of e-filing including MCA, GST, Income Tax, e-Tendering, and Trademark/Patent applications — regardless of what you may have read about older Class 1 or Class 2 certificates.
DSCs come in different certificate types depending on what you’ll use them for.
A DSC isn’t just a formality — it’s the gateway to fast, secure, legally valid digital transactions.
