Tax exemption for railway bonds granted subject to holder registration, securing tax-free status under specified income-tax provision. The Central Government designates '10 year-9% (tax free) Secured Redeemable Non-Convertible Railway Bonds (Second Issue)' issued by the Indian Railway Finance Corporation Limited as tax-exempt under the applicable income-tax provision, subject to the condition that the bondholder registers his or her name and holding with the Corporation; the notification both classifies the securities as eligible for tax-free treatment and makes registration a mandatory precondition to claim the exemption.
