Section 35AC exemption extends eligibility for specified leprosy, tuberculosis and integrated healthcare projects under the statute. The Central Government, under Section 35AC, specifies detection, treatment and cure of leprosy patients in urban Leprosy Control Projects, treatment of T.B. patients in a T.B. Control Project, and operation of an Integrated Healthcare Project at Airoli as eligible projects for income-tax exemption; this specification follows prior notifications, an enhanced estimated cost, and a National Committee recommendation under the Income-tax Rules to extend approval for a further period beginning with the stated assessment year.
