Verify Form 16 & Form 16A Digital Signature Online

When you download your Form 16 / 16A from the official TRACES CPC / Income Tax Department and view it in Adobe Acrobat Reader or default operating system previewers, you will see a prominent yellow question mark over the signature panel.

This warning occurs because consumer PDF viewers rely exclusively on the Adobe Approved Trust List (AATL), which consists predominantly of commercial Western certificate authorities. In contrast, the Government of India regulates sovereign digital signatures under the Information Technology Act, 2000 via the Controller of Certifying Authorities (CCA) and the Root Certifying Authority of India (RCAI).

Because Western software manufacturers do not bundle India's RCAI root keys by default, unconfigured readers cannot build the certificate validation chain. Kagazo bridges this gap by directly executing the CCA cryptographic validation and embedding a standards-compliant Document Security Store (/DSS) dictionary, rendering the signature permanently valid and green across all devices.

Form 16 is the annual Certificate of Tax Deducted at Source (TDS) on salary issued by employers under Section 203 of the Income Tax Act, 1961. Downloaded directly from the TRACES portal (TDS Reconciliation Analysis and Correction Enabling System), it contains Part A (tax deducted and deposited with the central government) and Part B (salary breakup and deductions).

Authentic Form 16 files are digitally signed by the employer's authorized representative using Class 3 DSCs issued under licensed Indian CAs (eMudhra, Capricorn, Pantasign, IDsign).

Kagazo supports password-protected Form 16 files (usually your PAN in capital letters) and validates the employer's signing certificate instantly.
