Why Income Tax e-Filing Needs a DSC

The Income Tax Department allows returns and forms to be verified either through Aadhaar OTP / EVC or through a registered Digital Signature Certificate. For certain categories of taxpayers, using a DSC isn't a matter of convenience — it's a statutory requirement. Explore our full range of DSC services for GST, MCA, and DGFT filings too.

Legally equivalent to a wet signature

A Class 3 DSC gives your electronically filed return, audit report, or reply to a notice the same legal standing as a physically signed and stamped document, as recognised under the Information Technology Act, 2000.

One-time registration, ongoing use

Once your DSC is registered against your PAN on the income tax e-filing portal, you can reuse it every assessment year — for ITR filing, audit reports, and any notice responses — until the certificate expires.

Who Must Use DSC

Is DSC Mandatory for Your Filing?

DSC-based verification is compulsory for some categories of taxpayers, and optional (in place of Aadhaar OTP/EVC) for others.

Mandatory

Companies filing ITR-6

Every company is required to verify its Income Tax Return using a Class 3 Organisation DSC — Aadhaar OTP/EVC is not an available option.

Mandatory

Taxpayers liable to tax audit

Individuals, firms, and LLPs whose accounts require a tax audit under Section 44AB must verify their return and audit report with a DSC.

Mandatory

Political parties & certain trusts

Political parties and specified trusts/institutions filing returns under audit provisions are also required to use DSC-based verification.

Optional

Individual taxpayers (not under audit)

Salaried individuals and other taxpayers not liable to audit can e-verify via Aadhaar OTP or net banking, or choose an Individual DSC instead.

Use Cases

Where You'll Use Your DSC on the Income Tax Portal
