Tax exemption for specified SCICI bonds requires holder registration with issuer to claim the tax-free interest benefit. Central Government specifies 15-year 9 per cent. SCICI Bonds (Series 2) as entitled to tax exemption under clause (15)(iv)(h) of section 10, with the exemption admissible only if the bondholder registers his name and holding with the issuing company, making issuer registration a prerequisite to claim the tax-free treatment.
