Answer
Taxpayers who sign an ITR or an audit report register a Class 3 signing DSC on the Income Tax e-Filing portal, in their own name or in the name of the firm. Chartered accountants use the same kind of certificate to sign Form 3CA and 3CB with 15CA and 15CB. We fill and submit the application for you; you do the Aadhaar OTP and video KYC with the Certifying Authority, which issues the certificate. Application support is included in the price.

Is a DSC mandatory for ITR filing?
Not for every ITR. A return filed without a DSC needs an OTP on the Aadhaar-linked mobile, so a DSC is what you use when the return is large, when you are signing an audit report, or when you do not want to depend on the OTP.
Can I use the same DSC for Income Tax and GST?
Yes, if the PAN on the certificate matches. Each portal has its own registration, done once with the certificate from the token.
What is the DSC Management Utility?
It is the small program the Income Tax portal uses to read your certificate from the token and sign the XML file behind a return, a Form 3CB or a Form 15CB. The portal prompts for it when it asks for a signature.
How do I register my DSC on the Income Tax portal?
Log in to the e-Filing portal, open Profile and Manage DSC, then Register DSC. Choose the certificate from the plugged-in token and enter the PIN.
Can a CA file Form 15CA and 15CB without a DSC?
Form 15CA and 15CB are signed digitally, so the CA signs them with a DSC on the token. That is the same Class 3 signing certificate, not a separate one.
What happens if my DSC expires in filing season?
The return or the report will not sign. Get the reissue before the expiry date; a certificate already on your token keeps working until it expires.
Is a new token needed every time?
Only if it is FIPS 140-3. Since 21 September 2026 new certificates cannot go on older FIPS 140-2 tokens, so any token bought before then will not work. A new token is an add-on at checkout.
