What is a Digital Signature for Income Tax?
A Digital Signature Certificate is mandatory for companies, LLPs, and taxpayers whose accounts are audited under Section 44AB to file their Income Tax Returns. Chartered Accountants also use a Class 3 DSC to upload tax audit reports and certificates on the Income Tax e-filing portal.
A DSC removes the need to send a physical ITR-V to CPC Bengaluru — your return is verified instantly upon signing. SignSecure issues Income-Tax-ready Class 3 certificates via paperless Aadhaar eKYC and helps you register them on incometax.gov.in.
