Specified bond exemption requires transferee to notify issuer within the prescribed period after transfer to retain tax benefit. Central Government specifies certain Secured Redeemable Non-Convertible Bonds (B-Series) issued by Indian Telephone Industries Limited, Bangalore, as qualifying for the tax concession under the relevant deduction provision; however, where such bonds are transferred by endorsement or delivery the tax benefit is admissible only if the transferee notifies the issuing corporation by registered post within the prescribed period after transfer.
