The Tamil Nadu Government delivers online verification for Income Certificates through the e-Sevai portal at [Link Provided Below]. The Income Certificate is a government-issued document issued as proof of the applicant's annual family income, used for fee waivers, scholarships, EWS reservation, fee concessions and welfare schemes. Citizens, employers, educational institutions, scholarship boards and government recruiters verify the authenticity of any Income Certificate issued in Tamil Nadu by entering the application reference number, holder's name and date of issue. The verifier page returns issuance status, holder demographic data and the certificate's validity period. The service is integrated with the State CSC network so applications, downloads and physical print outs are available at every Common Service Centre across the State. Authentication is also possible via the QR code printed on each digitally-signed certificate.
