Exemption notification under Section 10(23C)(iv) recognises charitable trust status and tax relief for specified assessment years. The Central Government, invoking Section 10(23C)(iv) of the Income tax Act, notifies The Annie Besant Trust, Madras as included within the exemption provision and specifies coverage for the assessment years 1985-86 to 1987-88, thereby registering the trust within the statutory exemption framework for that period.
