What is a DSC for income tax filing?
A Digital Signature Certificate for income tax filing is a Class 3 DSC used to digitally sign and verify Income Tax Returns and other forms on the Income Tax e-Filing portal — mandatory for taxpayers whose accounts require statutory audit under Section 44AB and for all companies.
Many taxpayers can verify ITR through Aadhaar OTP or EVC, but audit cases and companies often need DSC-based verification.
A DSC can also support tax forms, professional filings and authorised representative workflows where digital signing is required.
