Approved institution status requires exemption funds be used exclusively for social science research and reported annually to the authority. Approval under section 35(1)(iii) grants the institute tax-exempt status for funds collected under the exemption, conditional on exclusive use for promotion of social science research, maintenance of separate accounts for exempt funds, and submission of an annual report to the prescribed authority detailing collections and utilisation. The notification names the institute and fixes the date from which these obligations apply.
